Answer:
two
Step-by-step explanation:
In the case when there is a congruent rectangle so that represent the equal sides i.e. the width and the length would be the same.
Since it is mentioned that one rectangle JKLM has 4 inch and 7 inches dimension so there would be the possibility that the length of J M might be 4 or 7

please help!! i need help with numbers 3 and 4.
Answer:
3. Markup $3.50 Retail Price $13.50
4.)Markup $10 Retail Price $50
Answer:
3. $ Markup = $3.50
Retail Price = $13.50
4. $ Markup = $10
Retail Price = $50
Step-by-step explanation:
Turn the % markups into decimals. For 3, you would turn the % markup into 0.35 and for 4 you would turn the % markup into 0.25.
Multiply the decimals by the price. Your result for the $ markup for 3 should be $3.50 and the result for 4 should be 10.
Now add the $ markup to the original price for 3 and 4.
10 + 3.50 = $13.50
40 + 10 = $50

Farmer Bob needs to build a fencing for his poultry farm 40 metre long and 20 metre wide. What is the total length of fencing needed? Write the formula to find the answer.Required to answer.
Answer:
120 meters
Step-by-step explanation:
Bob's land is a rectangle, so it has 2 long and 2 short sides. The Long side is 40 meters long, and the short side is 20 meters long.
Let's add them: 40 + 20 = 60 meters
Since we have 2 of those sides, we will multiply it by 2 which we can demonstrate as
60 meters * 2 = 120 meters
please explain,
2(2w-9)=-38
Answer:
You first multiply the 2 with the numbers inside the parinthesis. So it'll be 2 x 2w and 2 x -9 which will get you to 4w-18. After that you add 18 to each side of the equation so the -18 can dissapear. After getting your answer you get left with 4w on the left side and -20 on the right. You then divide both sides with 4
Step-by-step explanation:
2(2w-9)=-38
4w-18= -38
+18 +18
4w = -20
4w/4= w
-20/4= -5
So in the end W= -5

Balena has a garden in the shape of a circle of radius 10 m.
He is going to cover the garden with grass seed to make a lawn.
Grass seed is sold in boxes.
Each box of grass seed will cover 46 m' of garden.
Balena wants to cover all the garden with grass seed.
Work out an estimate for the number of boxes of grass seed Balena needs.
Show your working out.
Answer:
7
Step-by-step explanation:
→ Work out area of circle
π × 10² = 100π = 314.159 (3 decimal places)
→ Divide area of circle by box area
314.159 ÷ 46 = 6.8295
→ Round answer as you can't get a decimal of a box
7
The area of a circle is given as πr².
The number of boxes of grass seeds required to cover the garden is 9 boxes.
What is a circle?A circle is a round-shaped figure that has no corners or edges.
The area of a circle is given as:
Area = πr²
We have,
The radius of the circle = 10 m
Area of the garden:
= πr²
We can take,
π = 22/7 = 3.14
= 3.14 x 10 x 10
= 314 m²
The area of a box of grass seeds:
= 46 m²
The number of boxes of grass seeds to cover the garden area:
= 314 / 46
= 6.8 boxes
Thus,
The number of boxes of grass seeds required to cover the garden is 9 boxes.

the blueprint of an aircraft carrier uses a scale of 1 inches= 120 feet if the aircraft carrier is 9 1/10 inches long on the blueprint, find its actual length.
Answer:
1,092 feet
Step-by-step explanation:
set up a proportion, then cross multiply:
let 'x' = actual length, in feet
[tex]\frac{1}{120}[/tex] = [tex]\frac{9.1}{x}[/tex]
The length of the given aircraft with the given scale factor will be 108 feet.
What is the scale factor?You must specify the extent of the shape's enlargement when describing one.
For example, 50 meters is very big so we cannot measure it but if we can convert it into 50 mm such that the scale ratio is maintained then it will be easy to draw.
Suppose the aircraft's actual length is L.
The ratio of actual length to blueprint
L/(9 1/10) = L/0.9
As per the given scale factor,
1 inches = 120 feet
120 feet = 1440 inches
i inches = 1440 inches
Thus, 1440/1 = L(0.9)
L = 1296 inches = 108 feet
Hence "The length of the given aircraft with the given scale factor will be 108 feet".

A train travels 430 miles in 5 hours at a constant speed. If its speed remains the same, how long will it take to travel the remaining 215 miles of its route?
Answer:
2.5 hours
Step-by-step explanation:
To get the hourly speed, we need to divide 430 by 5.
This means that the train is going at a speed of 86 miles/hour.
Since we need to find the hour, we need to divide 215 miles by 86 miles/hour.
[tex]215 miles / \frac{86 miles}{hour}[/tex]
We can use the keep change flip to do [tex]215 miles * \frac{1 hour}{86 miles}[/tex]

Answer: Should be quadrant 3
Step-by-step explanation:
1 is everything in -360
2 is everything in -270
3 is everything in -180
4 is everything in -90
So basically it is less than -90 so it couldn’t be in quadrant 4 it would be before it so quadrant 3. Sorry if this is incorrect but it is to the best of my knowledge

Can anyone help me get X
Answer:
X=38
Step-by-step explanation:
this is an isosceles triangle as we can see by the lines on the sides of the triangle. that means both of those sides are equal to 52.
52x2=104
A triangle adds up to 180. If two of the sides already equal 104 then the last side will be how much will go up to 180.
180-104=76
It is cut by a bisector DB meaning both sides will be equal. So divide 76 by 2 and we get 38
I can't really tell if x is for one side of angle b or both sides. If it is only for one side then it is 38 but if it is for the whole angle B then it is 76.

How many groups of 5/6 are in 1
9514 1404 393
Answer:
1 1/5
Step-by-step explanation:
We want to find the number of times (5/6) goes into 1, so we divide ...
1/(5/6) = 1 × 6/5 = 6/5 = 1 1/5
There are 1 1/5 groups of 5/6 in 1.
_____
Another way to look at it
You can consider 1 to be divided into 6 equal part:
o o o o o o
We can group these in groups of 5, so each group is 5/6 of the whole:
(o o o o o) o
What we see is that we have 1 group, and 1/5 of another group.
That is, 1 has 1 1/5 groups of 5/6 in it.

How many unique triangles can be formed with two side lengths of 10 centimeters and one 40° angle
Answer:
There are two unique triangles that can be formed two side lengths of 10 centimeters and one 40º angle.
Step-by-step explanation:
There are theoretically three unique triangles that can be formed with two side lengths of 10 centimeters and one 40º angle. We include a representation of possible triangles:
Case A - Law of Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]C = 40^{\circ}[/tex])
[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex] (1)
[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 40^{\circ}}[/tex]
[tex]c\approx 6.840\,cm[/tex]
Case B - Laws of Sine and Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]B = 40^{\circ}[/tex])
[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex] (2)
[tex]\sin A = \frac{a\cdot \sin B}{b}[/tex]
[tex]A = \sin^{-1}\left(\frac{a\cdot \sin B}{b} \right)[/tex]
[tex]A = \sin^{-1}\left[\frac{(10\,cm)\cdot (\sin 40^{\circ})}{10\,cm} \right][/tex]
[tex]A = 40^{\circ}[/tex]
[tex]C = 180^{\circ}-A-B[/tex]
[tex]C = 100^{\circ}[/tex]
[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex]
[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 100^{\circ}}[/tex]
[tex]c \approx 15.321\,cm[/tex]
Case C - Laws of Sine and Cosine ([tex]a = 10\,cm[/tex], [tex]b = 10\,cm[/tex], [tex]A = 40^{\circ}[/tex])
[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex]
[tex]\sin B = \frac{b\cdot \sin A}{a}[/tex]
[tex]B = \sin^{-1}\left(\frac{b\cdot \sin A}{a} \right)[/tex]
[tex]B = 40^{\circ}[/tex]
[tex]C = 180^{\circ}-A-B[/tex]
[tex]C = 100^{\circ}[/tex]
[tex]c= \sqrt{a^{2}+b^{2}-2\cdot a\cdot b\cdot \cos C}[/tex]
[tex]c = \sqrt{(10\,cm)^{2}+(10\,cm)^{2}-2\cdot (10\,cm)\cdot (10\,cm)\cdot \cos 100^{\circ}}[/tex]
[tex]c \approx 15.321\,cm[/tex]

What is the equation of the line that passes through the point (5,2) and has a
slope of -6
Answer: If the given slope is –6/5, the equation is
y –2 = –6/5(x -5)
The attachment shows the graph of this equation.
The point-slope form is y = –6x/5 + 8
Step-by-step explanation: The basic form for a point-slope equation is
y - b = m(x - a)
a is the x-value from the given coordinate, b is the y-value form the given coordinate, m is the slope. x and y are the variables in the function.
The slope, m, is given: -6/5 Substitute for m
Given coordinate points (5,2) substitute the x-value in place of a and the y-value in place of b
Rewrite the equation:
y - b = m(x - a) becomes
y - 2 = –6/5(x - 5)

Solve for x
9x - 7 = 4x + 13
i need help with this i’m so confused in this topic
Answer: x=4
Step-by-step explanation:
First, you need to take both of the x to one side of the equation. To do that, subtract 4x from both sides of the equation. you will get 9x-7-4x=4x+13-4x. The 4xs on the right hand side of the equation will cancel out. So you will be left with an equation that looks like this: 9x-7-4x=13. Now, on the left hand side of the equation you can rearrange the numbers to look like this. 9x-4x-7=13. Do 9x-4x to get 5x and then add back your -7 and the =13. Now, your equation will look like this. 5x-7=13. Now, you need to get rid of the 7 on the left hand side of the equation in order to isolate the variable (which is x here). The easiest way to do this would be to add 7 to both sides (in order to keep the equation balanced, whatever you do on one side of the equation has to also be done on the other side.) of the equation so the +7 and -7 could cancel each other out. You would have 5x-7+7=13+7. Now, cancel out the 7s on the left hand side of the equation. You would be left with 5x=13+7. Add the 13 and the 7 on the right hand side of the equation to get 20. You would now have the equation 5x=20. Finally, you need to isolate the x, right? To do that, just divide both sides of the equation by 5. you would get 5x/5=20/5. And your final answer after simplifying should be x=4. Hope this helps!
