A rectangular prism has a volume of 175 in'. The height of the prism is 7 in. The base is a square. What is the length of a side of the base? please help
Answer:
a=5cm
Step-by-step explanation:
V=B*H
You will get base if you do this:
B=V:H
B=175:7
B=25
I'm not so good with English, side is probably a,so:
Formula for base: B=a²
Then a=√B
a=√25
a=5cm

Kara has 10 books on a shelf and decides to move 3 of them to an empty shelf. In how many different ways can the empty shelf be filled?
The empty shelf can be filled in 120 ways
The total number of books is
[tex]n = 10[/tex]
The number of books to move is:
[tex]r = 3[/tex]
To fill the empty shelf with three books, we make use of the following combination formula
[tex]^{n}C_r = \frac{n!}{(n - r)!r!}[/tex]
So, we have:
[tex]^{10}C_3 = \frac{10!}{(10 - 3)!3!}[/tex]
Evaluate the expression
[tex]^{10}C_3 = \frac{10!}{7!3!}[/tex]
Expand
[tex]^{10}C_3 = \frac{10 \times 9 \times 8 \times 7!}{7! \times 3\times 2 \times 1}[/tex]
Cancel out the common factors
[tex]^{10}C_3 = \frac{10 \times 9 \times 8}{3\times 2 \times 1}[/tex]
Evaluate the products
[tex]^{10}C_3 = \frac{720}{6}[/tex]
Divide
[tex]^{10}C_3 = 120[/tex]
Hence, the empty shelf can be filled in 120 ways

11. Which could be the table of values that was used to graph the function of x shown below?
Answer:
D
Step-by-step explanation:
Here, we want to select the possible table of the given line
Let us look at the intercepts
On the x-axis, we have an intercept at x = 2
On the y-axis, we have an intercept at y = -4
This means that when y = 0, x = 2 and when x = 0, y = -4
Looking at the options, the table that supports this answer is the table of option D

The Thompson Family has a garden in their backyard. They take the produce each week to a local farmers market. Use the graph to answer question. What percent of the garden is tomatoes? Show work for full credit.
Answer: 20%
Step-by-step explanation:
The total # of plants is 30, so what you do is take the # of tomatoes over 30. (6/30) and then x/100 so the formula would be 6/30=x/100. Then you would cross multiply and solve! so your answer is 20%

Answer:
x = 50, y = 61
Step-by-step explanation:
y + 8 + 2x + 11 = 180°
y + 2x = 161°
the total of the interior angles of the 5 sided polygon is:
(180 x 5) - 360 = 540°
540 = 98 + 98 + 125 + 108 + 2x + 11
2x = 100
x = 50°
y + 2(50) = 161
y = 61°

What are trigonometric relations?Trigonometry can be stated as the study of the relationships between the angles and the lengths of the sides of triangles.
here, we have,
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
here, we have,
Given the graph:
The length of the shadow = y - x.
• To find x:
tan 21 = x/25
so, we get,
x = 25 * tan 21
=9.6m
• To find y:
tan 40 = y/25
so, we get,
y = 25* tan40
= 21m
Length of the shadow:
length = 21 - 9.6 m
= 11.4m
so, we get,
Length of the shadow = 11.4 m

Step-by-step explanation:
Lin and Noah are solving the equation `7(x+2)=91`. Lin starts by using the distributive property. Noah starts by dividing each side by 7. Show what Lin's and Noah's full solution methods might look like.
HELPPP
Answer:
Step-by-step explanation:
Lin’s method
- multiply both x and 2 by 7
7x+14 = 91
- add -14 at both members
7x+14-14 = 91-14
7x = 77
- divide the two members by 7
x = 11
Noah’s method
- divide the two members by 7
x+2 = 13
- add -2 at both members
x+2-2 = 13-2
x = 11
Answer:
The solution is x=11
Step-by-step explanation:
The original equation is
7(x+2)=91
Lin uses the distributive property, which states that
a (x+y) = ax + ay
By applying the property to this case,
7(x+2)=91
7x+14=91
Then we subtract 14 on both sides:
7x+14 - 14 = 91-14
7x=77
Finally, we divide by 7 on both sides:
7x÷7 = 77÷7
x=11
Noah starts by dividing each side by 7, so he gets:
7(x+2)÷7 = 91÷7
x+2= 13
Then he can subtract +2 from both sides:
x+2-2 =13 - 2
x=11
So, they get the same result. The similarity between the two methods is that they both divide by 7, while the difference is that Lin has to subtract 14, while Noah has to subtract 2.
