Answer:
8.54 units (3s.f.)
Step-by-step explanation:
Distance between 2 points
[tex] = \sqrt{(y1 - y2)^{2} + {(x1 - x2)}^{2} } [/tex]
Identify the coordinates of the 2 endpoints of the line:
(-5, 5) and (-2, -3)
Using the distance formula above,
length of line segment
[tex] = \sqrt{[5 - ( - 3)]^{2} + [ - 5 - ( - 2)]^{2} } \\ = \sqrt{ {(5 + 3)}^{2} + ( -5 + 2)^{2} } \\ = \sqrt{ {8}^{2} + {( - 3)}^{2} } \\ = \sqrt{73} \\ = 8.54 \: units \: (3 \: s.f.)[/tex]

22 – 25x + 5 = -63 + 5x
Answer: x = 3
Step-by-step explanation:
first, we calculate.
27 - 25x = -63 + 5x
then, we move the terms around.
-25x - 5x = -63 - 27
next, we collect the like terms.
-30x = -90
finally, we divide both sides.
x = 3

5. Jada is making circular birthday invitations for her friends.
The diameter of the circle is 12 cm. She bought 180
cm of ribbon to glue around the edge of each invitation.
How
many invitations can she make?
Answer:
Step-by-step explanation:
Jada is making circular invitations
we have d=12 cm, the radius r=6
she needs to find out the circumference
C=2x3.14x r
C=2x 3.14x6=37.68
180/37.68=4.77
she can make just 4 invitations
In Δ,∠=70°,∠=50° ∠ .
ℎ ∠.
Answer:
100°
Step-by-step explanation:
A triangle is a polygon shape with three sides. Triangles are of different types such as obtuse, scalene, equilateral, isosceles etc.
In triangle ABC:
70° + 50° + ∠C = 180° (sum of angles in a triangle)
120 + ∠C = 180
∠C = 180 - 120
∠C = 60°
Since ∠C is bisected into ∠ACD and ∠BCD, hence:
∠ACD = ∠BCD = ∠C / 2
∠ACD = ∠BCD = 60 / 2
∠ACD = ∠BCD = 30°
In triangle ACD:
∠A + ∠ACD + ∠ADC = 180° (sum of angles in a triangle)
50 + 30 + ∠ADC = 180
∠ADC + 80 = 180
∠ADC = 100°

4. A car travels 120 miles in the same amount of time that it takes a truck to travel 100 miles. The car travels 10 miles per hour faster than the truck. Find the speed of the truck
Answer:
The speed of the truck is 1,200 miles.
Step-by-step explanation:
Car = 10 MILES PER HOUT FASTER THAN THE TRUCK.
Truck = X times 10
X = 120 MILES times 10
120 times 10= 1,200, BECAUSE IF YOU TAKE THE "1" FROM "10" IT'LL BE "1" FROM THE 10, TIMES 120 MILES WHICH = 120. NOW TAKE THE "0" FROM THE 10 AND ADD *0* AT THE END OF THE ANSWER YOU GOT WHICH WAS "120." THEN YOUR ANSWER WILL BE 1,200 IF YOU ADD THE "0" AT THE END.
*and also useable on a calculator depending on your grade level*
Solve for f: ax+3b=2f
Final Answer: [tex]f = \frac{ax}{2} + \frac{3b}{2}[/tex]
Steps/Reasons/Explanation:
We will be trying to rewrite the equation. To do this we will move [tex]2f[/tex] to the left. Then, we will move [tex]ax + 3b[/tex] to the right.
Question: Solve for [tex]f[/tex]: [tex]ax + 3b = 2f[/tex].
Step 1: Rewrite the equation.
[tex]2f = ax + 3b[/tex]
Step 2: Divide each term by [tex]2[/tex] and simplify.
[tex]\frac{2f}{2} = \frac{ax}{2} + \frac{3b}{2}[/tex]
Step 3: Cancel out the common factor of [tex]2[/tex].
[tex]\frac{Cancel 2 f}{Cancel 2} = \frac{ax}{2} + \frac{3b}{2}[/tex]
Step 4: Divide [tex]f[/tex] by [tex]1[/tex].
[tex]f = \frac{ax}{2} + \frac{3b}{2}[/tex]

Find the area of the shaded regions. GIve your answer as a completely simplified exact value in terms of pi. (No approximations)
Answer:
A = 27π cm²
Step-by-step explanation:
Area of the shaded region = area of full circle of O - Area of the unshaded sector
= (πr²) - (θ/360*πr²)
Where,
r = 6 cm
θ = 360
Area of shaded region = (π*6²) - (90/360*π*6²)
= (36π) - (¼*π*36)
= 36π - 9π
Area of shaded region = 27π cm²

Given the equation: y= 2x +
graph the y-intercept. Use full sentences.
Answer:
In this equation, y = 2x - 5, it is already in that form and so the cumber in front of the x is the slope (2) and the constant number is the y-intercept (-5) - it's negative because of the minus sign in front of the number. So, the slope is 2 and the y-intercept is -5.

In the following circle paragraph what percent of the students have a C in Miss Rogers science class 81% 16% 19% or 21%
Given:
In Miss Rogers science class, 32%, 33%, 11%, 5% of students have A, B, D, F respectively.
To find:
The percent of the students have a C in Miss Rogers science class.
Solution:
We know that, sum of the percentages of all parts of pie chart is 100%. So,
[tex]A+B+C+D+F=100\%[/tex]
Substituting the given values, we get
[tex]32\%+33\%+C+11\%+5\%=100\%[/tex]
[tex]C+81\%=100\%[/tex]
[tex]C=100\%-81\%[/tex]
[tex]C=19\%[/tex]
So, 19% of the students have a C in Miss Rogers science class.
Therefore, the correct option is C.
Answer:
I think it's 81%

The following histogram shows the number of items sold at a grocery store at various prices:
Histogram titled Items Sold with Price Range on the x axis and Number of Items Sold on the y axis. Bar 1 is 0 to 2 dollars and 50 cents and has a height of 1. Bar 2 is 2 dollars and 51 cents to 5 dollars and has a height of 0. Bar 3 is 5 dollars and 1 cent to 7 dollars and 50 cents and has a height of 5. Bar 4 is 7 dollars and 51 cents to 10 dollars and has a height of 1.

{1, 0, 5, 1}
{0.99, 5.01, 5.25, 6.79, 6.99, 7.50, 7.51}
{0.75, 2.50, 7.50, 7.50, 7.50, 7.50, 10.00}
{2.50, 2.51, 5.00, 5.01, 7.50, 7.51, 10.00}
Answer:
{0.99, 5.01, 5.25, 6.79, 6.99, 7.50, 7.51} second option
Step-by-step explanation:
You can see from the histogram that there is
- one value = 0.99 that is from 0 to 2 dollars and 50 cents
- no values between 2 dollars and 51 cents and 5 dollars
- 5 values between 5 dollars and 1 cent to 7 dollars and 50 cents
-1 value between 7 dollars and 51 cents to 10 dollars
All the four bars the value of dollar fall between the range of 0 dollar to the 10 dollar. This condition satisfy only by the option C.
Hence, The option C is the correct option which is,
{0.75, 2.50, 7.50,7.50,7.50,7.50,10.00}
Given-
Histogram titled number of Items Sold with Price Range on the x axis.
Histogram titled number of Items Sold on the y axis.
The range of bar 1 is 0 to 2 dollars and 50 cents and has a height of 1. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 1 is 1 to 2.5 dollar.
The range of Bar 2 is 2 dollars and 51 cents to 5 dollars and has a height of 0. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 2 is 2.51 to 5 dollar.
The range of bar 3 is 5 dollars and 1 cent to 7 dollars and 50 cents and has a height of 5. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 3 is 0.01 to 7.5 dollar.
The range of bar 4 is 7 dollars and 51 cents to 10 dollars and has a height of 1. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 4 is 7.51 to 10 dollar.
In all the four bars the value of dollar fall between the range of 0 dollar to the 10 dollar. This condition satisfy only by the option C.
Hence, The option C is the correct option which is,
{0.75, 2.50, 7.50,7.50,7.50,7.50,10.00}

Answer:
4/3 or
Step-by-step explanation:
Let's get this equation into y=mx+b form.
m=slope b=y-int
Subtract 5 from both sides to isolate y on a side.
4x-6=3y
Divide both sides by 3 to isolate y on one side.
(4/3)x-2=y
y=(4/3)x-2
m=4/3
b=-2
So our slope is 4/3
Hannah has a chicken coop with 6 hens. Let X be the total number of eggs the hens lay on a randomly chosen day. The distribution for X is given in the table.
A 2-column table with 7 rows. Column 1 is labeled number of eggs with entries 0, 1, 2, 3, 4, 5, 6. Column 2 is labeled probability with entries 0.02, 0.03, 0.07, 0.12, 0.30, 0.28, 0.18.
What is the standard deviation of the distribution?
1.39

Answer:
1.39
Step-by-step explanation:
Creating a table:
X :___0 __ 1 __ 2 ___ 3 ____ 4 ___ 5 ___ 6
P(x):0.02_0.03_0.07, 0.12, 0.30_ 0.28_0.18.
The standard deviation = sqrt(Var(x))
Var(x) = Σx²*p(x) - E(x)²
E(x) = ΣX*p(x)
E(x) = (0*0.02) + (1*0.03) + (2*0.07) + (3*0.12) + (4*0.30) + (5*0.28) + (6*0.18) = 4.21
Var(X) :
((0^2*0.02) + (1^2*0.03) + (2^2*0.07) + (3^2*0.12) + (4^2*0.30) + (5^2*0.28) + (6^2*0.18)) - 4.21^2
19.67 - 17.7241

Standard deviation = sqrt(Var(X))
Standard deviation = sqrt(1.9459)
