The net of the solid is a plane shape, and The net of the solid is made from 6 faces
How to determine the number of faces?From the question, we understand that:
Sides = 5 trianglesBase = 1 pentagonSo, the number of faces is:
Face = Triangle + Pentagon
This gives
Face = 5 + 1
Face = 6
Hence, the net of the solid is made from 6 faces

Which expression is equivalent to 8-(6r+2)?
-6r+6
2r+2
6r+10
-6r+10
Answer:
-6r+6
Step-by-step explanation:
Let us expand the expression:
8-(6r+2)=
8-6r-2=
6-6r
OR
-6r+6
I hope this helps! :)
Answer:
6r+6
Step-by-step explanation:
we dont know the variable's number value yet so you can't solve anything with the 6r. We use distribbutive property and solve 8-2 since the 8 is just subtracting everything in the parenthesis. 8-2=6 and you can't do anything with the 6r so the expression would end up as 6r+6.
Connie Harris, in charge of office supplies at First Capital Mortgage Corp., would like to predict the quantity of paper used in the office photocopying machines per month. She believes that the number of loans originated in a month influence the volume of photocopying performed. She has compiled the following recent monthly data:
Number of Loans Originated in Month Sheets of Photocopy Paper
used (1000s)
45 22
25 13
50 24
60 25
40 21
25 16
35 18
40 25
(a) Develop the least-squares estimated regression equation that relates sheets of photocopy paper used to loans originated.
(b) Use the regression equation developed in part (a) to forecast the amount of paper used in a month when 42 loan originations are expected.
(c) Compute the coefficient of determination r2. Comment on the goodness of fit.
(d) Compute the correlation coefficient.
(e) Is there a significant relationship between the two variables? Use a significance level of 0.05 and explain using numerical examples.
Answer:
y = 0.325X + 7.5 ;
21.5 ;
R^2 = 0.7655 ;
r = 0.8749
Step-by-step explanation:
No. of loans originated ____ sheets of p/paper
45 ______________22
25 ______________ 13
50 _____________ 24
60 _____________ 25
40 _____________ 21
25 _____________ 16
35 _____________ 18
40 _____________ 25
Using the linear regression calculator : the linear model obtained is:
y = 0.325X + 7.5
y = predicted variable = sheets of photocopy paper
X = number of loans originated
0.325 = slope
Intercept = 7.5
B.)
X = 42
y = 0.325(42) + 7.5
y = 21.15
C.)
The Coefficient of determination as determined using the correlation coefficient calculator is :
R^2 = 0.7655 ; this means that about 76.55% of change in number of photocopy performed is explained by the number of loans originated.
D.) The correlation Coefficient (r) :
r = sqrt(R²)
r = sqrt(0.7655)
r = 0.8749
This shows that a strong positive correlation exists between the number of loans originated and the volume of photocopying done.
or a given recipe, 6 cups of flour are mixed with 12 cups of sugar. How many cups of flour should be used if 32 cups of sugar are used?
Answer:
16 cups of flour.
Step-by-step explanation:
Twelve is six twice, so if we need half the amount of flour we use for sugar, we just do 32 / 2 and you get sixteen!

In a sequence of 10 terms, the first term is 1, the second term is x, and each term after the second is the sum of the previous two terms. Is 12 the fifth term in the sequence?
Answer:
NO, 12 is not the fifth term in the sequence
Step-by-step explanation:
Given the sequence of 10 terms:
First term a1 = 1
second term a2 = x
third term a3 = a2+a1
Since each term after the second is the sum of the previous two terms then;
a3 = x+ 1
a4 = a3 + a2
a4 = x+1+x
a4 = 2x+1
Also
a5 = a4+a3
a5 = 2x+1+x+ 1
a5 = 3x+2
Get x:
The common difference d = a2-a1 = a3-a2
d = x-1 = x+1-x
x-1 = x+1-x
x-x+x = 1+1
x = 2
Get the fifth term:
Recall that a5 = 3x+2
a5 = 3(2)+2
a5 = 6+2
a5 = 8
Hence the fifth term of the sequence is 8 not 12

Please Help !!!!!!!!!!!!!!!!!!!!!!!!!!!!! 20% of your family likes marshmallows melted on top of the sweet potato casserole. If you have 18 people in your family, which proportion could be used to find the number of people who like marshmallows melted on top of the sweet potato casserole?
A : 20/100 = 18/ x
B : 18/20 = x/100
C : x/18 = 20/100
D : 20/x = 18/100
Answer:
C
Step-by-step explanation:
let's say the 18 was the 100 and x was the 20% of that 100, if they equal the same just take 20% of 18 (you will get 3.6)
Therefore is C : x/18 = 20/100.
express 1400 as a product of its prime factors in index form write the prime factors in ascending order?
Answer:
[tex]1400=2^3*5^2*7[/tex]
Step-by-step explanation:
Prime Factors
The first prime numbers are:
{1,3,5,7,11,13,...}
To find the prime factors of any integer number, we successively divide the number by all the possible prime numbers, probably more than once.
Let's find the prime factors of 1400.
Dividing by 2 while possible:
1400/2 = 700
700/2 = 350
350/2 = 175
3 is not a divisor of 175, so we try 5:
175/5 = 35
35/5 = 7
Since the last result is a prime number, no more tries are necessary. The product of prime factors in index form is:
[tex]\boxed{1400=2^3*5^2*7}[/tex]
Factor 7w2−175.(1 point)
−7(w−25)
7(w−25)
7(w−5)(w+5)
7(w−5)(w−5)
Answer:
7(w + 5)(w -5)
Step-by-step explanation:
a² - b² = (a + b)(a - b)
7w² - 175 = 7w² - 7*25
= 7(w² - 25)
= 7(w² - 5²)
= 7(w + 5)(w -5)

What percent of 4 is 7?
7 is the number 175 percent of 4.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Let n be the required percentage.
So,
n percent of 4 is 7.
That means,
4 x n/100 = 7
n = 700/4
n = 175%
Therefore, 175% is the required percentage.

If f(x) = x2 -3, then what is f(-5)?
Answer:
22
Step-by-step explanation:
So if you have f(x) = x^2 - 3, then all you have to do is plug in x = -5 into the equation. This would be (-5)^2 - 3 = 25 - 3 = 22.

Simplify the following expression. log(x^4) -log(x^3) O A. log(x1 - x3) B. log(x) C. log(x4 + x3) O D. log(x)
The simplified form of the given logarithms expression log(x⁴) - log(x³) is logx, Option D is correct by properties of logarithms.
Using the property of logarithms that states "the difference of the logarithms of two numbers is the logarithm of the quotient of the two numbers,"
we can simplify the expression as:
log(x⁴) - log(x³) = log(x⁴/x³)
We know that x⁴/x³ = x⁴⁻³
= x,
log(x⁴) - log(x³) = log(x)
Therefore, the answer is (D) log(x).

Determine the length of AY if ARAY is a 30°-60°-90° triangle and RY has a length of 48 centimeters.
Answer:
48√3 cm
Step-by-step explanation:
I'm assuming that ∠A = 30°, ∠R = 60°, and ∠Y = 90°.
The sides of a 30-60-90 triangle are in the ratio 1:√3:2.
RY is opposite the 30° angle and has length 48 cm.
AY is opposite the 60° angle, so the length of AY = 48√3 cm.
