Nina used 3 1/2 pounds of apples to make apple sauce. She used 3/4 times as many apples to make apple pies. How does the number

of pounds of apples Nina used for apple pies compare to the amount she used for applesauce? Explain your reasoning.

Answer:

x=6

Step-by-step explanation:

We can use ratios to determine the value of x

x 9

------ = ----------

10 15

Using cross products

15x = 9*10

15x = 90

Divide each side by 15

15x/15 =90/15

x = 6

A surveyor sights the far bank of a river at an angle of 110° to the near bank. She then moves 75 feet upriver and sights the sa

Leya [2.2K]

Answer:

Correct answer is 54.82 ft.

Step-by-step explanation:

First of all, let us label the diagram and do the construction as per the attached answer image.

Let us consider $\triangle ABC$ :

$\angle B = 90^\circ\\\angle ACB = 180-110 = 70^\circ$

Let side AB = d ft and let side BC = x ft

We need to find AB to find the shortest distance across the river.

Using trigonometric identity of tangent:

$tan\theta = \dfrac{Perpendicular}{Base}$

$tan 70 = \dfrac{d}{x}\\\Rightarrow x = \dfrac{d}{tan70} = 0.36d ..... (1)$

Now, let us have a look at another right angled triangle ABD:

Let us consider $\triangle ABC$ :

$\angle B = 90^\circ\\\angle ADB = 180-150 = 30^\circ$

side AB = d ft and side BD = x+75 ft

Using trigonometric identity of tangent:

$tan\theta = \dfrac{Perpendicular}{Base}$

$tan 30 = \dfrac{d}{x+75}\\\text{Using equation (1)}:\\0.577 = \dfrac{d}{0.36d+75}\\\Rightarrow 0.207d + 43.27 = d\\\Rightarrow 0.793d = 43.27\\\Rightarrow d \approx 54.82\ ft$

Correct answer is 54.82 ft.

Answer:

D) (2, 14)

Step-by-step explanation:

substitute each coordinates into the inequality:

(0, 0)

y > 5x

0 > 5*0

0 > 0

this is false, 0 = 0.

(3, 12)

y > 5x

12 > 5 * 3

12 > 15

this is false, 12 < 15

(-2, -10)

y > 5x

-10 > 5 * -2

-10 > -10

this is false, -10 = -10

(2, 14)

y > 5x

14 > 5 * 2

14 > 10

this is true, 14 > 10
