Each student walks to school or cycles to school or gets the bus to school.
There are 23 girls in the class.
10 of the girls walk to school.
6 of the boys cycle to school.
7 of the 11 students who get the bus to school are boys.
Find the number of these students who walk to school.
Your final line must say, Number who walk to school = ...

If Carl mowed 4 yards for $35, how much will he get for mowing 7 yards?
Answer:
61.25 dollars
Step-by-step explanation:
We can use a ratio to solve
4 yards 7 yards
-------------- = -----------------
35 dollars x dollars
Using cross products
4x = 35*7
4x =245
Divide each side by 4
4x/4 = 245/4
x =61.25
How is the length of the image of a line segment under a dilation related to
the length of its pre-image?
Answer:
It is dilated by the scale factor
Step-by-step explanation:
For example is one line is 2 units long and the image of that line was 4 units long the scale factor would be 2. (2 x 2 = 4.) If it was the other way around with the 4 as the original line and the 2 as the image line the scale factor would be 1/2. (1/2 x 4 = 2)
Answer:
260 units
explanation:
A dilation with a scale factor is noting but an increase in size of geometrical figure by a certain value.in the circumstances the line AB is 5 units. being a line AB has no width, so it only increases in length. if you want new length, it's simple.all that's nessary multiply the orgin length by the scale factor.
5.52=260
the solution is 260 units.
A group of friends is going on a trip. They must pay a total of $681 to rent a bus for their trip. Along with the bus rental fee, the friends will also need to spend a total of $2,150 on hotels for the week. To pay for the cost of the bus and hotel, the friends held a bake sale and raised $691. They then decided to sell candy for $4 a bag of candy to cover the remaining costs. How many bags of candy must the friends sell?
Answer:
$535
Step-by-step explanation: $681 + 2,150 = 2831 $2831- 691 = 2,140 $2,140/4 = 535 which means they need to sell 535 candy more.

A tennis supply store pays a wholesaler $90 for a tennis racquet and sells it for $150. What is the markup rate?
(Quantity = Percent x Whole)
Answer:
Markup 66.6666666......% = 66 2/3 % (66 and 2/3 percent)
Step-by-step explanation:
The difference in prices is $150-$90=$60. So, we need to find what percentage of 90 is 60. We do this by dividing: 60/90=0.6666...., which is 66.666...%. So, the markup is 66.666...%. = 66 2/3 %
Rewrite in factored form. g(x)=2x^2+10x+12
Answer:
. g(x)=2x^2+10x+12=2x²+6x+4x+12=2x(x+3)+4(x+3)
=(x+3)(2x+4)=2(x+2)(x+3)
Answer:
2(x + 3)(x + 2)
Step-by-step explanation:
All three terms of g(x)=2x^2+10x+12 have the factor 2, so
g(x)=2x^2+10x+12 = 2(x^2 + 5x + 6).
This can be factored further, into:
2(x + 3)(x + 2)

Step-by-step explanation:
This is an airthmatic sequence
we can use the following equation to find the nth term
a₁+(n-1)d
where the common difference (d) is 5
and the first term (a₁) is 10
and n is 75
we have
10+(75-1)*5

Answer: Fred's Slope
Step-by-step explanation:
Comparing the slope were are looking at the numerator or y of the slope to find which one takes you the highest compared to the others.
Start with Sam who has a slope of 2/11 or rise 2 run 11 which is pretty flat so sam is out
Fred and Anne both have a slope that is a whole number so we're lloking for the bigger number which would be Fred
Anne's slope is 4.75
sams slope is 2/11
and fred’s is 5

please help i dont understand
Given:
Number of spheres = 2
Number of prisms = 3
Number of pyramids = 5
To find:
The probability that a pyramid will be selected.
Solution:
We have,
Favorable outcomes = Number of pyramids
= 5
Total outcomes = Total number of figures
= [tex]2+3+5[/tex]
= [tex]10[/tex]
Now, the required probability is:
[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Probability}=\dfrac{5}{10}[/tex]
[tex]\text{Probability}=0.5[/tex]
Therefore, the probability that a pyramid will be selected is 0.5.

Answer:
16.5 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the other leg, then
x² + 13² = 21²
x² + 169 = 441 ( subtract 169 from both sides )
x² = 272 ( take the square root of both sides )
x = [tex]\sqrt{272}[/tex] ≈ 16.5 cm ( to the nearest tenth )
What is the distance between points (-7, 8) and (2, 8)?
Answer:
Exact Form:
2 √ 34
Decimal Form:
11.66190378
The distance between points (-7, 8) and (2, 8) is 9 units.
Formula to calculate distance between two points:The distance d between two points [tex](x_{1},y_{1}),(x_{2},y_{2})[/tex] is,[tex]d=\sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-y_{1})^{2} }[/tex]
For given question,
Let [tex](x_{1},y_{1}) = (-7,8),(x_{2},y_{2})=(2,8)[/tex]
Let d be the distance between two points.
Using distance formula,
[tex]d=\sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-y_{1})^{2}[/tex]
[tex]d=\sqrt{(2-(-7))^{2}+ (8-8)^{2} }[/tex]
[tex]d=\sqrt{(2+7)^{2}+0^{2}[/tex]
[tex]d=\sqrt{9^{2}+0 }[/tex]
[tex]d=9[/tex] units
Hence, the distance between points (-7, 8) and (2, 8) is 9 units.
