Answer:

16 boxes

Step-by-step explanation:

160+50x=1000

Solve for the x and you'll get 16.8. Now, because you can't have a fraction of a box, and you can't go over the limit, the answer is 16 boxes.

(How to solve for x:

Get x by itself by subtracting 160 to both sides.

50x=1000-160

50x=840

Divide both sides by 50.

x=16.8)

COLLEGE PREP In the diagram, mLAGC = 38°, m/CGD=71°, and m/FGC = 147 °. Which of the following
Cerrena [4.2K]

The statements that are true are:

A. m<AGB = 19°

D. <BGD is a right angle

<h3>What is a Right Angle?</h3>

A right angle is an angle that measures 90 degrees.

Given the diagram, where:

m<AGC = 38°,

m<CGD = 71°,

m<FGC = 147°

We have the following measures:

1/2(m<AGC) = m<AGB

1/2(38) = 19°

m<CGD + m<AGC = m<BGD

Substitute

71 + 19 = m<BGD

90 = m<BGD

m<BGD = 90° [this is a right angle].

Therefore, the statements that are true are:

A. m<AGB = 19°

D. <BGD is a right angle

Find the length of JL<br> 15<br> None of the other answers are correct<br> 12<br> 3
r-ruslan [8.4K]

Answer:

D: 12

Step-by-step explanation:

The entire segment KI is composed of the segments KJ and JI. So:

KI=KJ+JI

We know that KI is 15.

KJ is (2x-15) and JI is (2x-6). Substitute:

15=(2x-15)+(2x-6)

Solve for x. Combine like terms:

15=4x-21

Add 21 to both sides:

4x=36

Hence, the value of x is:

x=9

We know that JI is 2x-6.

We will substitute 9 for x to find JI. So:

JI=2(9)-6=18-6=12

Hence, our answer is D.

G evaluate lim h → 0 (1 + h)9 − 1 h . hint: this limit represents the derivative of a function f at a given point
Bond [772]
\displaystyle\lim_{h\to0}\frac{(1+h)^9-1}h

Write 1=1^9, and recall that for a differentiable function f(x), the derivative at a point x=a is given by

f'(a)=\displaystyle\lim_{h\to0}\frac{f(a+h)-f(a)}h

which would suggest that for this limit, f(x)=x^9 and a=1. We have f'(x)=9x^8, and so the value of the limit would be 9(1)^8=9.

What is the answer to 35-4xless than 2
Taya2010 [7]
You first need to get x on one side, so you first subtract 35 from both sides, and you get
-4x < 2
then you divide by -4 on both sides, so you get
x < -0.5
(i hope this is correct)
