Charlotte and Riley walked 6/10 of a mile to school one day, and then after school they walked 3/8 of a mile to the store. From the store back home was another 2/5 of a mile. How far did the girls walk in all?
Answer: The girls walked [tex]1\dfrac38[/tex] miles.
Step-by-step explanation:
Given: Distance from home to school = [tex]\dfrac{6}{10}[/tex] mile
Distance from school to store = [tex]\dfrac38[/tex] mile
Distance from store to home = [tex]\dfrac25[/tex] miles
Total distance = [tex]\dfrac6{10}+\dfrac38+\dfrac25[/tex]
= [tex]\dfrac{6\times4+3\times5+2\times8}{40}[/tex] [L.C.M.(10,8,5)=40]
= [tex]\dfrac{24+15+16}{40}[/tex]
= [tex]\dfrac{55}{40}[/tex]
= [tex]\dfrac{11}{8}=1\dfrac38[/tex] miles
Hence, The girls walked [tex]1\dfrac38[/tex] miles.

For the two right triangles above, explain why a/8=x/12 . What trigonometric ratio is also equal to the two given ratios?
Answer:
sin trigonometry ratio
Step-by-step explanation:
Given
See attachment for triangles
Required
Explain why [tex]\frac{a}{8} = \frac{x}{12}[/tex]
From the attached diagram, both triangles are similar triangles because
(1) the second triangle is a dilation of the first triangle by a ratio of 1.5
i.e
[tex]k = \frac{12}{8}[/tex]
[tex]k = 1.5[/tex]
(2) They have angle 30 degrees, and have their right angles located at the same point
In the first triangle, the sine of 30 degrees is represented as:
[tex]sin(30) = \frac{Opp}{Hyp}[/tex]
This gives:
[tex]sin(30) = \frac{a}{8}[/tex]
In the second triangle:
[tex]sin(30) = \frac{Opp}{Hyp}[/tex]
So:
[tex]sin(30) = \frac{x}{12}[/tex]
By comparison:
[tex]sin(30) = sin(3)[/tex]
Hence:
[tex]\frac{a}{8} = \frac{x}{12}[/tex]

Find the slope of the line that passes through (2, 4) and (9, 9).
(a) Whats the area of a rectangular field is 3888 m. If the length of the field is 72 m, what is its width?
(b)The perimeter of a rectangular painting is 374 cm. If the width of the painting is 88cm, what is its length?
Answer:
part a is 54 part b is 99
Step-by-step explanation:
72 x ? =3888
x=54
374 is the perimeter. You have a side that is 88cm so the opposite side will be 88 cm as well. 374-176=198
so between the last 2 sides we have 198. The sides will be equal so you just divide it by 2
so the top and bottom of the rectangle are 99 and both sides are 88

A rectangular window is 4x inches wide and 8x inches long. What is an expression for the distance from one corner of the window to the opposite
corner? Give your answer as a simplified radical.
Answer:
Step-by-step explanation:
Pythagorean theorem
a² + b² = c² a = 4x b=8x
c = √(a² + b²)
c =√((4x)² + (8x)²)
= √(16x² + 64x²)
= √80x²
= √(16×5)x²
= 4x√5

A salesman earns 20% commission on all the merchandise that he sells. Last month he sold $900 worth of merchandise. How much commission (in dollars) did he earn last month?
Answer: $180
Step-by-step explanation:
Given
Salesman earns 20% commission on merchandise he sells
Last month sales by him are $900
So, his commission out of $900
[tex]\Rightarrow 20\%\ \text{of}\ 900=0.2\times 900\\\Rightarrow \$180[/tex]
So, he grabbed $180 dollar as commissions
When the door was left open, 36 pigeons flew the coop. If this was 40 percent of all the pigeons, how many pigeons were there originally?

Explanation:
This tent is a triangular prism. We have two congruent triangles in front and back. Let's stand the triangular prism up so that the triangle forms the base, or floor, of this figure.
The area of the base triangle is 5*4/2 = 20/2 = 10 square feet. I used the formula base*height/2 to get the area of a triangle.
Once we know the area of the base of the prism, we multiply that by the height of the prism, which is the 8 ft. So we get 10*8 = 80 cubic feet of volume.
