Answer:
[tex]4.2\ \text{cm}[/tex]
Step-by-step explanation:
d = Diameter of wheel
The difference between the circumference and diameter of a wheel is 18 cm.
[tex]2\pi r-d=18\\\Rightarrow \pi d-d=18\\\Rightarrow d(\pi-1)=18\\\Rightarrow d=\dfrac{18}{\pi -1}\\\Rightarrow d=\dfrac{18}{3.14-1}\\\Rightarrow d=8.41\ \text{cm}[/tex]
The diameter of the wheel is 8.41 cm so the radius will be [tex]\dfrac{8.41}{2}=4.205\approx 4.2\ \text{cm}[/tex].

In one basketball game, Zaid made 7 two-point and three-point baskets to score 17 points. Let x represent the number of two-point baskets, and y represent the number of three-point baskets. This situation can be represented by the system x+y=7 and 2x+3y=17 . How many of each type of basket did Zaid make?
Answer:
y =three point score = 3
x = two point score = 4
Step-by-step explanation:
this question can be solved using simultaneous equation
x + y = 7 eqn 1
2x + 3y = 17 eqn 2
Multiply eqn 1 by 2 to derive eqn 3
2x + 2y = 14 eqn 3
Subtract eqn 3 from 2 :
y = 3
Substitute for y in eqn 1
x + 3 = 7
x = 4

If there are 180 students in the girls athletics program, then
how many students participated in soccer?
Answer:
27
Step-by-step explanation:
15: 100 = x : 180
x = (180 x 15) / 100 = 27
Answer:
27
Step-by-step explanation:
Seems like your question(shown/written) is incomplete. Based on the given data.
15% of the total students participated in soccer
15% of 180 students participated in soccer
=> 15/100 x 180
=> 2700/100
=> 27
27 students participated in soccer

The sum of all the probabilities must add up to 100%
Simplify the expression 6x + 9 + 3x -x by combining like terms?
Answer:
Group the like terms
6x + 3x - x + 9
Work out the x values together and then add the 9
9x - x + 9
8x + 9
your final answer should be about 8x + 9 as it cannot be simplified anymore
True or False: The relationship is a proportional relationship.
Answer:
false
Step-by-step explanation:
when graphing a proportional relation ship you should be able to draw a straight through all the points
example
A = 2^3 x 3 x 5
B = 22 x 3 x 52
(b) Write down the highest common factor (HCF) of A and B.
Answer:
Step-by-step explanation:
B = 22 × 3 × 52?—or is it supposed to be
B = 2² × 3 × 5² ?
A = 2² × 3 × 5
B = 2² × 3 × 5²
GCF = 2² × 3 × 5 = 60
A = 2² × 3 × 5
B = 22 × 3 × 52 = 2³ × 3 × 5 × 11 × 13
GCF = 2² × 3 × 5 = 60

Find the interior angle sum of this polygon.
Can someone help????
===================================================
Explanation:
See the diagram below. It shows there are 10 sides, so n = 10.
We'll plug this value of n into the formula below to find the sum of all ten interior angles
S = sum of interior angles
S = 180(n-2)
S = 180(10-2)
S = 180(8)
S = 1440 degrees
---------------
A different approach:
Let's assume this polygon is a regular polygon. This means each angle is congruent to one another.
We have n = 10 sides, so each exterior angle is E = 360/n = 360/10 = 36 degrees.
Each interior angle adjacent to this 36 degree exterior angle is
180-E = 180-36 = 144 degrees
Since we have 10 equal angles of 144 degrees each, so overall the interior angles add to 10*144 = 1440 degrees
Side note: if this polygon is not a regular polygon, then this section does not apply. You would use the first method instead.
The table below gives the dimensions of a bridge and a scale model of the bridge.
Find the scale factor of the model to the real bridge.
Write your answer as a fraction in simplest form.
Answer:
Scale factor = [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Formula for the scale factor is,
Scale factor = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the original}}[/tex]
= [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the bridge}}[/tex]
= [tex]\frac{\text{Width of the model}}{\text{Width of the bridge}}[/tex]
= [tex]\frac{7}{35}[/tex]
= [tex]\frac{1}{5}[/tex]
Therefore, scale factor of the model to the real bridge = [tex]\frac{1}{5}[/tex]

Mrs. Smith cuts 1 2 of a piece of construction paper. She uses 1 6 of the piece to make a flower. What fraction of the sheet of paper does she use to make the flower?
Answer:
1/12 fraction of the sheet of paper is used to to make the flower
Step-by-step explanation:
The size of the piece of paper cut from the construction paper = 1/2
Amount of paper used from this piece to make flower = 1/6
Total amount of construction paper used = 1/2 * 1/6
= 1/12

-3 = 3/4r + 2
find r
Answer:
r = -20/3
Step-by-step explanation:
can i get brainliest plz
Answer:
-20/3
Step-by-step explanation:
3/4r + 2 = -3
subtract 2 on both sides...
3/4r = -5
divide by 3/4 on both sides...
3/4r divided by 3/4 is r.
-5 divided by 3/4 is the same thing as...
-5 times 4/3 (flip the fraction)
-20/3
