Answer:
In two similar geometric figures, the scale factor is the ratio of their corresponding sides, dividing the two corresponding lengths of the sides will gives the ratio, for example
What is the scale factor between 4 cm and 10 cm ?
4 and 10 are divisible by 2
Length A : 4 ÷ 2 = 2
Length B : 10 ÷ 2 = 5
so the scale factor from A to B is 2:5
Write the equation of the line that passes through the points (-6, 4) and (-3,-2).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y=-2x-8
Step-by-step explanation:
-2-4/-3-(-6)=-6/3=-2
y-4=-2(x-(-6))
y-4=-2(x+6)
y-4=-2x-12
y=-2x-12=4
y=-2x-8
Amy has the cards below:
3, 4, 5, 6, 7, 8
Select the letter that matches the probability of the dice landing on 3:
(diagram in the image attached).
Answer:
B (1/6)
Step-by-step explanation:
The cards she draws doesn't affect what number the dice lands on. 1 every 6 times on average the dice lands on 6 so there is a 1/6 probability represented by B.

CAN SOMEONE PLEASE HELP ME ON THIS
Answer:
a) $525 CAD
b) $168.30 per day
c) $38.05
Step-by-step explanation:
a) 1 USD = 500
1.05CAD x
cross-multiply: x = $525 CAD
b) 504.90 / 3 = 168.30 per day
c) 1 USD = x
1.05CAD 39.95
cross-multiply: 1.05x = 39.95
x = 39.95 / 1.05
x = $38.05 USD

Answer:
5
Step-by-step explanation:
-8x + 25 = -15
-25 = -40 then
-40 divide -8 to get 5
Answer: x = 5
The first step of the inverse operation is to subtract 25 on both sides of the equation to cancel out the 25 from the left side:
-8x+25 (-25) = -15 (-25)
-8x = -40
Next, you need to divide -8 on both sides to isolate the variable, which would give you the answer to x. The negatives would cancel out, leaving you with: x = 5
hope that helps :)

Use the Distributive Property to evaluate the expression.
(16 - 6)2
Answer:
20
Step-by-step explanation:
Bob and Sue are meeting on a stairway. Bob is at the top and Sue is at the bottom. There are 9 steps
from bottom to top. Bob can skip a step each time since he is going down, Sue will not skip any steps. On
which step will they meet.
Answer:
Bob is at the top, so he starts at step 9.
Sue is at the bottom, so she is at the step 0 (this is the floor, before stepping on step 1)
Sue climbs from one step on one step.
Then she if she climbs n times, she will be at the step number:
S(n) = 0 + 1*n
And Bob goes down by 2 steps each time, then after he goes down n times, his position will be:
B(n) = 9 - 2*n
We want to see when they meet, then we need to solve:
S(n) = B(n)
1*n = 9 - 2*n
1*n + 2*n = 9
3*n = 9
n = 9/3 = 3
n = 3.
This means that they meet a the step:
S(3) = 3*1 = 3
B(3) = 9 - 2*3 = 9 - 6 = 3
They meet at the third steep.

An angle measures 148° more than the measure of its supplementary angle. What is the measure of each angle? AND DONT PLAGERISE!!!
Answer:
Step-by-step explanation:
Supplementary angles add up to 180°.
“θ is 148° more than its supplement”
Supplement of θ = 180°-θ
θ = (180°-θ) + 148°
2θ = 328°
θ = 164°
Supplement of θ = 180°-164° = 16°

Hi guys!
(Please help me if you have time)
Answer:
528 m
Step-by-step explanation:
circumference = 2(Pi)(radius) = (2)(22/7)(28) = 176 m
176 x 3 = 528 m
Answer:
528m
Step-by-step explanation:
given the radius 28m, we can find the circumference of the circle using the formula C=2pi×r
substitute the given into the formula we get C=2(22÷7)×28, since pi is equals to 22/7.
C=176m
Now we multiply the result by 3 since it says that it took three rounds, we have 176m×3= 528m
Hope this helps you...
The circumference of a circle is 25π cm. What is the area, in square centimeters? Express your answer in terms of \piπ.

[tex]156.25 pi square centimetersGiven the figure as marked. What is x?
Answer:
6
Step-by-step explanation:
Using the similarity theorem f the triangle
(4+6)/x+9 = 4/x
10/x+9 = 4/x
Cross multiply
10x =4(x+9)
10x = 4x+36
10x-4x = 36
6x = 36
x = 6
Hence the value of x is 6
