Answer:

Step-by-step explanation:

3/4 inch to 1 mile = 1 3/4(or 7/4 in) to x miles

make a proportion

(3/4) (7/4)

-------- = ------- cross multiply

1 x

(3/4)(x) = (7/4)(1)

3/4x = 7/4

x = (7/4) / (3/4)

x = 7/4 * 4/3

x = 7/3 or 2 1/3 miles <===

Dmitry [639]

Answer:

Option D. 3:1, $120

Step-by-step explanation:

The complete question in the attached figure

Part 1) What is the ratio between the amount of money contributed by Anna and the amount contributed by her mother?

Let

x -----> the amount of money contributed by Anna

y ----> the amount of money contributed by her mother

we know that

Looking at the table

The value of x is equal to $x=\$30+\$60+\$90+\$120=\$300$

The value of y is equal to $y=\$10+\$20+\$30+\$40=\$100$

Find the ratio x/y

substitute the values

$\frac{x}{y}=\frac{300}{100}=\frac{3}{1}$

Part 2) What was the total amount saved in April?

we know that

To find out the total amount saved in April, adds Mon's contribution in April plus Anna's contribution in April

$(\$30+\$90)=\$120$

A 20 ft ladder leans against a building and reaches a point 13 ft above the ground. Find, to the nearest degree, the angle that

Snezhnost [94]

Since it forms a "right triangle" we can apply trigonometry.
sin x = oppo/hyp
sin x = 13/20
x = sin^-1(13/20)
x = sin^-1(0.65)
x = 40.5
rounded to nearest degree
x = 41 degrees

Hope this helps! :)

t = $\frac{I}{Pr}$

isolate t by dividing both sides by Pr

$\frac{I}{Pr}$ = t ⇒ t = $\frac{I}{Pr}$
