Answer:
62
Step-by-step explanation:
surface area of a rectangular prism = 2lw + 2lh + 2wh
Where l = length, w = width and h = height
The box has the following dimensions
length = 5 in
width = 3 in
height 2 in
Using these dimensions, we plug in the values into the formula
[tex]SA=2(5*3)+2(5*2)+2(3*2)\\5*3=15\\15*2=30\\5*2=10\\10*2=20\\3*2=6\\6*2=12\\SA=30+20+12\\30+20+12=62[/tex]
Hence, the surface area = 62

solve the inequality 1 - 2x + - 7
Answers
Answer: x = -3 or if not solving for x then -2x -6
Step-by-step explanation:
1 - 2x - 7 = 0
-6 - 2x = 0
add 2x on both sides
-6 = 2x
divide 2 on both sides
-6/2 = x
x = -3
If y varies inversely as x and y= 24 when x = 4. find y when x = 3.
A. 32
B. 18
C. 2
D. 288
Answers
Answer:
A. 32
Step-by-step explanation:
y varies inversely as x
y = k/x
-------------------------
y = 24 when x = 4
find k, the constant of variation
24 = k/4
multiply both sides by 4
96 = k
----------------------------
find y when x = 3
using k = 96
y = 96/3
y = 32

Answers
Answer:
d
Step-by-step explanation:
The correct option is C. The amount of time in the sun is the response
variable.
Given, An experiment is conducted to measure the effectiveness of a brand of sunscreen.
A response variable measures an outcome of a study. An explanatory variable attempts to explain the observed outcomes. The explanatory variable is usually called independent and the response variable is called dependent.
From the above definition it is clear that A response variable is dependent quantity so here in question, option c states that the amount of time in the sun is the response variable which is right because it is totally depend on the brand of sunscreen.
Hence the correct option is C. The amount of time in the sun is the response
variable.

Sally and Suzie both agree that m∠A + m∠B = 180⁰.
Sally claims ∠A and ∠B are supplementary.
Suzie claims ∠A and ∠B are not supplementary because they are not adjacent.
Who is correct?
Answers
Explanation:
The angles do not need to be touching, or adjacent, for them to be supplementary. They simply need to add to 180 degrees.
We have 70+110 = 180, so that proves the angles are supplementary. They can be rearranged to glue together to form a straight angle.
If the angles were supplementary and adjacent, then we can consider them as a linear pair. This is possibly what Suzie might be thinking about.

Answer:
a) Lateral area of the solid = 2011.43 [tex]cm^{2}[/tex]
b) Surface area of the solid = 2544 [tex]cm^{2}[/tex]
Step-by-step explanation:
a) Lateral area of the figure = 2[tex]\pi[/tex]rh
where; r is the radius of the cylinder, and h is its height.
Lateral area of the figure = 2 x [tex]\frac{22}{7}[/tex] x 10 x 32
= 2011.43 [tex]cm^{2}[/tex]
b) The surface area = 2[tex]\pi[/tex]r(r + h) - 2([tex]\frac{1}{2}[/tex] x b x h)
= 2[tex]\pi[/tex]r(r + h) - (b x h)
The height of the isosceles triangle can be determined by applying the Pythagoras theorem to have,
[tex]10^{2}[/tex] = [tex]6^{2}[/tex] + [tex]h^{2}[/tex]
100 = 36 + [tex]h^{2}[/tex]
[tex]h^{2}[/tex] = 100 - 36
= 64
h = [tex]\sqrt{64}[/tex]
= 8
h = 8 cm
The surface area of the solid = 2 x [tex]\frac{22}{7}[/tex] x 10 (10 + 32) - 12 x 8
= 2640 - 96
= 2544
The surface area of the solid is 2544 [tex]cm^{2}[/tex].

Step-by-step explanation:
Hi there!
The formula to find the volume of a cylinder is r²πh, where r is the radius, π is pi, and h is the height
first, let's find the area of the circle (r²π)
we are given that the radius is 9 cm
so we can square the 9, which is the same as multiplying it by itself
(9*9)=81π
Your answers leave everything in pi, so we can leave the area of the circle as is :)
now, multiply 81π by the height, which is given as 8 cm
81π*8=648π
therefore the answer is 648π cm³

The average number of Saturday night shootings is 5 a night. What’s the chance that there will be a need for exactly 3 shootings this Saturday?
Answers
Answer:
0.14
Step-by-step explanation:
Using the poisson probability relation :
P(x = x) = (λ^x * e^-λ) ÷ x!
From the question ; mean, λ = 5 ; x = 3
Hence,
P(x = 3) = (5^3 * e^-5) ÷ 3!
P(x = 3) = (125 * 0.0067379) / 6
P(x = 3) = 0.8422375 / 6
P(x = 3) = 0.140
The number 42 has the prime factorization 2 · 3 · 7. Thus, 42 can be written in four ways as a product of two positive integer factors (without regard to the order of the factors): 1 · 42, 2 · 21, 3 · 14, and 6 · 7. Answer a–d below without regard to the order of the factors. (a) List the distinct ways the number "858" can be written as a product of two positive integer factors. (Enter your answer as a comma-separated list of products.)
Answers
Answer:
[tex]1 * 858,\ 2 * 429,\ 3 * 286,\ 11 * 78,\ 13 * 66,\ 6 * 143,\ 22 * 39,\ 26 * 33[/tex]
Step-by-step explanation:
Given:
[tex]Number = 858[/tex]
Required
List all its distinct product of two numbers
First, we list out the prime factors of the given number.
We have:
[tex]Number = 2 * 3 * 11 * 13[/tex]
So, the possible products are:
(1) 1 and the integer itself.
[tex]1 * 858 = 858[/tex]
(2) 1 prime factor and the product of other primer factors
[tex]2 * 429 = 858[/tex]
[tex]3 * 286 = 858[/tex]
[tex]11 * 78 = 858[/tex]
[tex]13 * 66 = 858[/tex]
(3) A pair of prime factors and the product of remaining primer factors
[tex]6 * 143 = 858[/tex]
[tex]22 * 39 = 858[/tex]
[tex]26*33 = 858[/tex]
Hence, the list are:
[tex]1 * 858,\ 2 * 429,\ 3 * 286,\ 11 * 78,\ 13 * 66,\ 6 * 143,\ 22 * 39,\ 26 * 33[/tex]
Zach scored 67 on his calculus class final and was devastated by his failing grade. His class distribution had a mean of 54 and a standard deviation of 7. Adam was quite proud of his score of 88 for his Spanish language class. His class distribution had a mean of 97 with a standard deviation of 6. Who did better relative to their class
Answers
Answer:
Due to the higher z-score, Zach did better relative to his class.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In this question:
Whoever had the higher z-score did better:
Zach:
Scored 67, mean of 54 and standard deviation of 7, so [tex]X = 67, \mu = 54, \sigma = 7[/tex].
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{67 - 54}{7}[/tex]
[tex]Z = 1.86[/tex]
Adam:
Scored 88, mean 97, standard deviation of 6, so [tex]X = 88, \mu = 97, \sigma = 6[/tex]
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{88 - 97}{6}[/tex]
[tex]Z = -1.5[/tex]
Who did better relative to their class?
Due to the higher z-score, Zach did better relative to his class.
