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.

According to the table below, what is the probability that the grade of a student chosen at random will be a B or higher? Grade A B с D F 4 Probability 2 35 3 35 17 35 9 35 35 3 OA. B. 7 Oc. VIN O D. / SUBMIT
Answer:
1 / 7
Step-by-step explanation:
Given the distribution above :
P(grade B or higher) can be defined explicitly as :
P(Grade A) + P(Grade B)
P(grade A) = 2/35
P(Grade B) = 3 / 35
Hence,
P(Grade B or higher) = 2/35 + 3/35 = 5/35 = 1/7

Prove that: log b (p2 - q2) – log b (p + q) = log b (p – q)
Answer:
Step-by-step explanation:
The formulas used to solve :
[tex][ log_b(\frac{x}{y}) = log_bx - log_by][/tex]
[tex](p^2 - q^2) = (p+q)(p-q)[/tex]
[tex]log_b(p^2 - q^2) - log _b(p + q) = log_b(p-q)\\\\log_b(\frac{(p^2 -q^2)}{(p+q)}) = log_b(p-q)\\\\log_b(\frac{(p+q)(p-q)}{(p+q)}) = log_b(p-q)\\\\log_b(p-q) = log_b(p-q)\\\\[/tex]
Hence proved.

Answer:
D
Step-by-step explanation:
Let w represent the width
Length=18+W
And width=w
So area of a Triangle equals (length times width)divided by two
Area=(18+w)(w)/2
And the area is given to us as 189
180=(18w+w^2)/2
Multiplying both sides by two yields
360=18w+w^2
The subtract 360 from both sides to get
w^2 +18w-360=0
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]

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

Emma signed up for a streaming music service that costs $6 per month . The service allows Emma to listen to unlimited music, but if she wants to download songs for offline listening, the service charges $0.75 per song. How much total money would Emma have to pay in a month in which she downloaded 40 songs? How much would she have to pay if she downloaded s songs ?
a Cost for 40 songs :
Cost for s songs :
Answer:
She would have to payed 36 dollars;
for the second part, i dont get it
Step-by-step explanation:
.75x40= 30
30+6 = 36
Answer:
Cost for 40 songs: $36
Cost for s songs: 0.75s + 6
Step-by-step explanation:
Set up an equation:
Variable s = number of songs
Variable x = number of months
0.75s + 6x
Solve for 40 songs in 1 month:
0.75(40) + 6(1)
30 + 6
$36
Solve for s songs:
0.75s + 6(1)
0.75s + 6
Maria is planting a row of flowers in a bed 28 feet long. The instructions say to space the plants 1 foot apart, allowing room for 28 flowers. The flowers come in flats containing 6 plants per flat.
How many flats will she need?
How many plants will she have left over?
Answer:
She will need 5 flats.
She will have 2 plants left over.
Step-by-step explanation:
Since she needs 28 flowers and there are 6 flowers in each plant.
To find the number of flats she needs simply divide 28 by 6
=28/6
=4.67
=Rounding off we get 5
Now we know that she need 5 flats so 5 flats will contain 5*6= 30 flowers total.
Since she has space for 28 flowers only the remainder will be;
30-28=2
Therefore she will have 2 plants leftover.

6
y-intercept= (0, -4)
slope = 3
Answer:
Step-by-step explanation:
Y-intercept of line is 14
slope of line = (0 - 14)/(10 - 0) = -14/10 = -7/5
Required equation is y = -7/5 x + 14
Answer:
y=3x-4
Step-by-step explanation:
The slope-intercept form of the equation of a line is written in y=mx+b
where m is the slope and b is the y-intercept
So in that form
y=mx+b becomes
y=3x-4 using your slope of 3 and y-intercept of -4

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 17 Pennies 10 Dimes 19 Nickels 23 Quarters What is the probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny
Answer:
0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability of grabbing a nickel:
19 nickels out of 17+10+19+23 = 69 coins, so:
[tex]P(A) = \frac{19}{69}[/tex]
Probability of grabbing a penny, considering the first coin grabbed was a nickel:
17 pennies out of 68 coins. So
[tex]P(B|A) = \frac{17}{68} = \frac{1}{4}[/tex]
What is the probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny?
[tex]P(A \cap B) = P(A)P(B|A) = \frac{19}{69} \times \frac{1}{4} = \frac{19}{69*4} = 0.0688[/tex]
0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.
