Workers load 5 identical large crates and 3 identical small crates onto a freight elevator. The crates have a combined weight of 1375 pounds. Later
that day, the workers load 3 more identical large crates and 6 more identical small crates onto the freight elevator. These crates have a combined
weight of 1350 pounds.
What is the weight of each crate?
A. Each large crate weighs 185 pounds, and each small crate weighs 150 pounds.
B. Each large crate weighs 200 pounds, and each small crate weighs 125 pounds.
C. Each large crate weighs 225 pounds, and each small crate weighs 112.5 pounds.
D. Each large crate weighs 250 pounds, and each small crate weighs 100 pounds.
Answer:
B. Each large crate weighs 200 pounds, and each small crate weighs 125 pounds.
Step-by-step explanation:
Let L be the weight of the large crate and S the weight of the small crate.
Given that 5 identical large crates and 3 identical small crates have a combined weight of 1375 pounds,
5L + 3S = 1375 (1)
Also, in the second loading 3 identical large crates and 6 identical small crates have a combined weight of 1350 pounds,
3L + 6S = 1350 (2)
multiplying equation (1) by 2 and (2) by 1, we have
5L + 3S = 1375 (1) × 2
3L + 6S = 1350 (2) × 1
10L + 6S = 2750 (3)
3L + 6S = 1350 (4)
Subtracting (4) from (3), we have
7L = 1400
dividing through by 7, we have
L = 1400/7
L = 200
Substituting L = 200 into (1), we have
5L + 3S = 1375 (1)
5(200) + 3S = 1375 (1)
1000 + 3S = 1375
3S = 1375 - 1000
3S = 375
dividing through by 3, we have
S = 375/3
S = 125
So, each large crate weighs 200 pounds, and each small crate weighs 125 pounds.

Find the measure of the arc or angle indicated.
9514 1404 393
Answer:
arc AC = 63°
Step-by-step explanation:
Arc BC is twice the measure of inscribed angle BAC, so is ...
arc AC = 2×89° = 178°
The remaining arc of the circle is the difference between 360° and the sum of the other two.
arc AC = 360° -119° -178°
arc AC = 63°

Answer:
I think C is correct answers im not sure though
The only given function that is an exponential decay function is;
C: f(x) = ³/₂(⁸/₇)⁻ˣ
Exponential decay function
Now, the general formula for exponential decay function is;
f(x) = abˣ
where b is the decay factor.
Now, the decay factor which we will call the base of the exponent must be greater than 1 .
Also, the exponent x must be negative to be called an exponential decay function.
Looking at the given options, only Option C meets the criteria for an exponential decay function.
The given options are;
A) f(x) = ³/₄(⁷/₄)ˣ
B) f(x) = ²/₃(⁴/₅)⁻ˣ
C) f(x) = ³/₂(⁸/₇)⁻ˣ
D) f(x) = ¹/₃(-⁹/₂)ˣ

The difference of the measures of the angles is 35º.
What is the slope of the line?
Pls help! I’ll mark the brainliest
Answer:
m = -3
Step-by-step explanation:
Two poin on this line are (-2, 3) and (0, -3). Both points are formed where grid lines meet precisely.
The change in x as we go from (-2, 3) to (0, -3) is +2 and the change in y is -6. Thus, the slope of the line shown is m = rise/run = -6/2, or m = -3.

Find the equation for the line that passes through the points ( 7 , 2 ) and ( 10 , − 6 ) . Give your answer in slope intercept form
Answer:
y = [tex]\frac{-8}{3}[/tex]x + [tex]\frac{62}{3}[/tex]
Step-by-step explanation:
Use slope formula.
then substitute slope for m in y = mx + b
pick a set of coordinates and substitute them in for x and y.
Solve for b
Answer:
[tex]y=-\frac{8}{3}x+\frac{62}{3}[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0)
1) Determine the slope (m)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (7,2) and (10,-6)
[tex]m=\frac{2-(-6)}{7-10}\\m=\frac{2+6}{7-10}\\m=\frac{8}{-3}[/tex]
Therefore, the slope of the line is [tex]-\frac{8}{3}[/tex]. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-\frac{8}{3}x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=-\frac{8}{3}x+b[/tex]
Plug in one of the given points and solve for b
[tex]2=-\frac{8}{3}(7)+b\\2=-\frac{56}{3}+b[/tex]
Add [tex]\frac{56}{3}[/tex] to both sides to isolate b
[tex]2+\frac{56}{3}=-\frac{56}{3}+b+\frac{56}{3}\\\frac{62}{3}=b[/tex]
Therefore, the y-intercept is [tex]\frac{62}{3}[/tex]. Plug this back into [tex]y=-\frac{8}{3}x+b[/tex]:
[tex]y=-\frac{8}{3}x+\frac{62}{3}[/tex]

In the graph above, what's the distance between (–1, –4) and (–1, 5)?
9514 1404 393
Answer:
9 units
Step-by-step explanation:
The graph shows a vertical line at x = -1, with points at y=-4 and y=5. The distance between the points is the difference of their y-coordinates:
5 -(-4) = 5+4 = 9
You can count the grid squares between the points, if you like.
The distance between the points is 9 units.

Answer:
The measure of angle D and A must be equal.
Step-by-step explanation:
ASA means angle-side-angle. So you must have two angles and the side between them be congruent to the other triangle. We already know Angle C and F are congruent and Side lengths AC and FD are congruent. So we just need the angles on the other side of the side lengths.
The function f (t) = 310(0.2)24t represents the change in a quantity over 7 days,
What does the constant 0.2 reveal about the rate of change of the quantity?
the rate percentage
Answer:
80% decrease in the quantity over 7 days
Step-by-step explanation:
Given data
We have the function
f (t) = 310(0.2)24
the above function is similar to the exponential function
f (t) = P(1±r)^t
Now the value 0.2
This means that there is 80% decrease in the quantity over 7 days
