Higher Order Thinking A railroad car container can hold 42,000 pounds. Mr. Evans wants to ship 90 ovens and some freezers in the same container. If each freezer weighs 600 pounds, how many freezers could be shipped in the container? Explain.
The number of freezers that can be shipped depends on the weight of an oven.
Total Weight: 42000 pounds
Weight of 90 ovens: 90w, where w is the weight of each oven.
Remaining weight to fill with freezers: 42000-90w
Weight of each freezer: 600 pounds
# of freezers that could be shipped: Remaining weight / freezer weight = (42000-90w)/600 = 70-3/20w
ANSWER: [tex]70-\frac{3}{20}w[/tex], where [tex]w[/tex] is the weight of each oven

10 ) Which Property of Multiplication is shown? (5 + 3) x 2 = 5 x 2 + 3 x 2
A. Identity Property
C. Associative Property
B. Distributive Property
D. Commutative Property
Answer:
B. Distributive Property of Multiplication
Step-by-step explanation:
The given equation shows that two similar expressions are equal to each other.
How? Well, they both equal 16 to start. These are the same expressions - one is just distributed out!
[tex]2 \cdot (5 + 3) \\2 \cdot 5 + 2 \cdot3 \\10 + 6 = 16[/tex]
and...
[tex]5 \cdot 2 + 3 \cdot 2\\10 + 6\\16[/tex]
In the equations, the only difference is that we distributive 2 and multiplied in by 5 and 3!

The cost of 1 pound of peanuts will be $2.5.
What is mean by Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The cost of 3 pounds peanuts will be $7.50.
That's mean;
Cost of 3 pounds peanuts = $7.50.
Now,
To find cost of 1 pound of peanuts we can divide $7.50 by 3 as;
Since, The cost of 3 pounds peanuts = $7.50
Hence, The cost of 1 pounds peanuts = $7.50 ÷ 3
The cost of 1 pounds peanuts = $2.5
Thus, Cost of 1 pounds of peanuts is for $2.5.
Therefore, The cost of 1 pound of peanuts will be $2.5

Suppose you are standing 19 feet from the base of a flagpole. You are able to determine that the angle of elevation to the top of the pole is 64.60 . Determine the height of the flagpole.
Answer:
40 ft
Step-by-step explanation:
Given that the angle of elevation is 64.6°, this means that the angle of depression from the top of the flagpole is 180 - 90 - 64.6, which is 25.4°
We can solve by using the sine rule, or the cosine rule.
Using the sine, we have
Sinθ = OPP/HYP, we're going to use the angle of depression, and thus
Sin 25.4° = 19/x, on rearranging, we have
x = 19/ sin 25.4°
x = 19/0.4289
x = 44.30 ft.
Now, we use Pythagoras theorem to get the height of the flagpole.
44.3² = 19² + y²
y² = 44.3² - 19²
y² = 1962.49 - 361
y² = 1601.49
y = √1601.49
y = 40 ft
A survey of 50 retail stores revealed that the average price of a microwave was $375 with a sample standard deviation of $20. Assuming the population is normally distributed, what is the 99% confidence interval to estimate the true cost of the microwave
Answer:
The 99% C.I is ( 367.703, 382.297 )
Step-by-step explanation:
Given that:
sample mean [tex]\overline x[/tex] = 375
Population standard deviation [tex]\sigma[/tex] = 20
Sample size n = 50
The level of significance [tex]\alpha[/tex] = 1 - C.I = 1 - 0.99 = 0.01
From z tables:
The critical value = [tex]Z_{\alpha /2}[/tex] = [tex]Z_{0.005}[/tex] = 2.58
The margin of error E = [tex]Z_{\alpha /2}[/tex] [tex]\times \dfrac{\sigma }{\sqrt{n}}[/tex]
The margin of error E = [tex]2.58 \times \dfrac{20}{\sqrt{50}}[/tex]
The margin of error E = 7.297
The limits of 99% C.I are expressed as:
Lower limit = [tex]\overline x - E[/tex] = 375 - 7.297
Lower limit = 367.703
Upper limit = [tex]\overline x + E[/tex] = 375 + 7.297
Upper limit = 382.297
The 99% C.I is [tex]\overline x \pm E[/tex] = [tex]375 \pm 7.297[/tex]
= ( 367.703, 382.297 )

What is the y-intercept on this table?
Answer:
the y intercept is 1 at the point (0,1)
Step-by-step explanation:
the y-intercept is when x = 0 because the x-axis is how many you go over, so if you go over none and up or down some, the point lies on the y-axis, and when a point lies on the y-axis, it's the y-intercept.

Answer:
A. 5/8
Step-by-step explanation:
If you want to find the equivalent of 1/2 in 8ths, what times 2 will give you 8? The answer is 4, so multiply the numerator and denominator by 4 to get 4/8. So, 4/8 is equal to 1/2, meaning that 5/8 is greater than 4/8. Hope this helped!

Michael can ride his bike 3 miles in 24 minutes. At this rate, what is the distance, in miles, Michael can ride his in one hour?
Answer:
7.5 miles
Step-by-step explanation:
3x=24
x=8
60/8
7.5
Answer: 480 miles
Explanation: To find the distance Michael rode in miles, we have to find how many minutes he can ride in one mile. So we will divide 24(minutes) into 3(miles).
24 ÷ 3 = 8
Michael can ride 1 mile in eight minutes.
Since there are sixty minutes in one hour, multiply eight by sixty to find how many miles Michael can ride his bike.
8 × 60 = 480
Micheal can ride 480 miles in one hour.

The formula for the area of a triangle is A= 1/2 bh, where b is the base of the triangle and h is the height of the triangle. What is the length of the base if the area is 22cm? and the height is 8 cm?
Answer:
The length of the base = 5.5cm.
Step-by-step explanation:
A = 1/2 bh
A = 22cm^2 h = 8cm.
22 = 1/2 b(8)
22 = 4b
hence b = 5.5cm.

Plzzz help
Answer:
y=5x+24
Step-by-step explanation:
Use formula y=mx+b and insert the given values
x = -4
y = -6
m = 5
-6 = 5(-6) + b
-6 = -30 + b
+30 +30
24 = b
Now you have value of b, rewrite the equation.
y=5x+24
