Given:
This table shows the ratio of apples to oranges.
Apples Oranges
6 10
9 15
12 ?
To find:
The missing value in the table of equivalent ratios.
Solution:
Let the missing value be x.
The ratios of apple and oranges are equivalent. So,
[tex]\dfrac{6}{10}=\dfrac{9}{15}=\dfrac{12}{x}[/tex]
[tex]\dfrac{3}{5}=\dfrac{3}{5}=\dfrac{12}{x}[/tex]
[tex]\dfrac{3}{5}=\dfrac{12}{x}[/tex]
On cross multiplication, we get
[tex]3\times x=12\times 5[/tex]
[tex]3x=60[/tex]
Divide both sides by 3.
[tex]x=20[/tex]
Therefore, the missing value is 20.
Answer:
20

36/52
45/65
An equivalent fraction for a/b is found by multiplying the numerator and denominator by a common integer (n)
In the figure, m∠2=(20x+52)° and m∠7=(40x-48)°
For what value of x is m || n ?
Enter your answer in the box.
x = ___
Answer: x=5 m is parallel to n
Step-by-step explanation:
∠2 and ∠7 are alternate exterior angles so they are equal.
So you can create the equation
40x-48 = 20x+52 Subtract 20x from both sides. Add 48 to both sides.
20x = 100
x = 5
if you need m∠2 Substtute 5 for x in 20x+52
20(5) + 52 = 100 +52 m∠2= 152°
m∠7 40(5) - 48 = 200-48 m∠7= 152°
Answer:
x=5 and m is parallel to n

A piece of wire is 25 cm and has a weight of 10 grams. Another piece of the same wire is 30 cm long. Calculate the weight of the 30 cm piece of wire. working out please
Answer:
75 grams
Step-by-step explanation:
If 25 cm = 10 grams
Then 1 cm = 25/10
1 cm = 2.5 grams
To find 30 cm = 2.5 times 30 grams
30 cm = 75 grams

Find the intercept form (-4,2), (4,7)
Answer:
y=5/8x+4.5
Step-by-step explanation:
You have to do y-y divided by x-x so 7-2 which equals 5 and 4-(-4) which equals 8 so your slope is 5/8. For y-intercept, you have to do plug in one of your points into y and x in y=mx+b, so I used the point (4, 7) and I put 7 in the y spot and 4 in the x spot and I put the slope in the slope spot so now you have 7=5/8(4)+b. Next, you multiply 5/8 and 4 which gives you 5/2 or 2.5, so now you have 7=2.5+b. Then you subtract 7-2.5 which gives you 4.5 and there is your y-intercept and your whole equation is y=5/8x+4.5.

A truck is carrying 9 cars weighing an average of 4,000 pounds each. What is the total weight in tons of the cars on the truck
Answer:
18 tons
Step-by-step explanation
First you need to know that 1 ton is 2,000 pounds. Ok so if you do the 4,000 pounds times the 9 cars you get 36,000 pounds in total and then you can divide by 2,000 and you get 18 so it is 18 tons.

what is the value of k?
Answer:
(4k+5)+ (6k+10) = 115
Exterior angle of a triangle is equal to the sum of two opposite interior angles
10k=15=115
10k= 100
k = 100/10
k = 10
Step-by-step explanation:
Answer:
k = 10
Step-by-step explanation:
The 3rd angle that's not defined in the equation is supplementary to 115, so the angle is 180-115 = 65.
We can solve for the equation 65+(4k+5)+(6k+10)=180 -> 65+4k+5+6k+10=180 -> 10k+80 = 180 -> 10k = 100 -> k = 10.
To double-check(optional), we can plug k back into the equation, so 65 + 4*10 + 5 + 6*10 + 10 = 180 -> 100 + 65 + 5 + 10 = 180 -> 180 = 180, so we can confirm that k = 10.

You have to use the KEEP CHANGE CHANGE method. When you do this you end up with 4/7*5/1 which equals 20/7 and you then change that into a mixed number and you have your answer!
HOPE THIS HELPS!
Answer:
The answer is 2 6/7
Step-by-step explanation:
First, you set up the problem.
[tex]\frac{4}{7} / \frac{1}{5}[/tex]
Next, you change the division sign into multiplication
[tex]\frac{4}{7} x \frac{1}{5}[/tex]
Then you flip the 1/5
[tex]\frac{4}{7} x \frac{5}{1} \\[/tex]
Afterward, you multiply fractions straight across.
[tex]\frac{4}{7} x \frac{5}{1} =\frac{20}{7}[/tex]
Finally, you will simplify your answer into a mixed number.
[tex]\frac{20}{7} = 2 6/7[/tex]

Suppose you need to build a box with a surface area of 90 square feet. If the length is 5 feet and the height is
2 feet, what is the width of the box?
Answer:
Hi there!
Your answer is:
W=17.5feet
Step-by-step explanation:
We use the surface area form for a cuboid:
2h(l+w)=SA
Fill in the known values!
2(2)* (5+ W) = 90
Solve for W!
4*(5+W)=90
20+4w=90
-20
4w=70
/4
W=17.5feet
