Answer:
The correct option is D
D) 340 inch²
Step-by-step explanation:
The base of the pyramid is a square with side 10 inch
Area of square base = Length · Width = 10 · 10
Area of square base = 100 inch²
Height of triangle = 12 inches
Base of triangle = 10 inches
Area of triangle = (1/2)(Height)(Base) = (1/2)(12)(10)
Area of triangle = 60 inch²
Total number of triangles in a pyramid = 4
Total Area of 4 triangles = 4 · 60 inch²
Total Area of 4 triangles = 240 inch²
Surface Area = Area of 4 triangle + Area of the square base
Surface Area = 240 inch² + 100 inch²
Surface Area = 340 inch²

Which of the following functions best describes this graph?
Answer:
Answer D is correct. The two factors (x - 6) and (x - 3) become zero at x = 6 and x = 3, respectively, showing the x-intercepts of this graph. Additionally, we can see that the sign of the leading coefficient of f(x) = (x - 6)(x - 3) is +, which indicates that the curve opens up. This agrees with the given graph.

find the values of x and y
Answer:
x = 85 Degrees
y = 85 Degrees
Step-by-step explanation:
20 Degrees + 90 Degrees -->
90 and 20 are given => 110 Degrees
e triangle angles sum = 180 Degrees
180 - 110 = 70 Degrees
=> Vertical angles so 25 + x + 70 = 180
x = 85
x + (z) = 180 e sum of half 360
85 + z = 180
z = 95 Degrees
--> z + (y) = 180 e same as above (sum of interior angles)
95 + y = 180
y = 85

10m6
Answer:
C ) 10/m⁵
Step-by-step explanation:
In this question, we have to find the product of two terms
First term = 5 m⁻²
Second term = 2 m⁻³
Product of both terms = (5 m⁻²) · (2 m⁻³)
The simple way of calculating product of these two term which involves constants as well as variable is that we multiply the constants together:
5·2 = 10
And we multiply the variables. According to the rules of multiplication, when 2 same constants or variables are multiplied, we can just add their powers to get the result.
(m⁻²) · (m⁻³) = m⁻²⁻³ = m⁻⁵
The product of both terms can be written as:
(product of constants)(product of variables) = (10)(m⁻⁵) = 10/m⁵
So the correct option is C

What is the area of a rectangle with vertices (-8, -2), (-3,-2).(-3,-8), and (-8, -B)?
Answer:
The area of the rectangle would be 20 square units.
Step-by-step explanation:
The distance between the points (-8, -2) and (-3,-2) is 5. This is the length of the rectangle. The distance between (-3,-6) and (-3,-2) is 4. This is the width of the rectangle. To find the area, multiply the length and the width to get the 20 square units as the area.
Answer:
Area = 20
As B = -4
Where -3-1 = -4
We look at x for first measure = -8 -3 = 5
We look at y first sequence change for second measure = -B
x/y = -3-8 /-8 + B
= -3-8 = -8(-8)+B
B = -3+B = -3+1
B= -3+1 = -4
Second measure = -8-4 = 4
Therefore, using both measures in bold : the Area = 4 x 5 = 20

Carmela wants to take out a loan for a car. Which benefit will Carmela receive if she makes a down payment when she obtains the loan?
A. a decrease in the total cost of the loan
B. no penalties for late payments
C. an increase in the loan term
D. an increase in the principal amount
Answer:
A) a decrease in the total cost of the loan
Step-by-step explanation:
plato/edmentum
Besides, there's very, very rarely no penalties for late payments and making a down payment wont prevent that. It wont increase the loan amount because you are paying more in advance. It also wont increase the principal amount, in fact, it decreases it.

Solve x+ y = 5 and 2 x - y = 3
Answer:
[tex] x=\frac{8}{3}\: \: y=\frac{7}{3}[/tex]
Step-by-step explanation:
Add the two equations:
$ x+y +(2x-y)=5+3$
$\implies 3x=8$
$\implies x=\frac{8}{3}$
Use this value in the first equation:
$\frac{8}{3}+y=5$
$\implies y=\frac{15-8}{3}=\frac{7}{3}$
Answer:
x + y = 5 Equation 1
2x-y = 3 Equation 2
Add both Equations
y will be eliminated so it will be
3x = 8
x = 8/3
Substitute x into equation 1
8/3 + y = 5
y = 5 - 8/3

handled in 1995 than in 2010?
Answer:
[tex]1 \times 10^{10}[/tex] more pieces of mail were handled in 1995 than in 2010.
Step-by-step explanation:
We are given that in 1995, the USPS approximated that they handled [tex]1.8 \times 10^{11}[/tex] pieces of mail and in 2010, the USPS reported that they handled [tex]1.7 \times 10^{11}[/tex] pieces.
To find how many more pieces of mail were handled in 1995 than in 2010, we do subtraction of the pieces of mail that were handled in both the years.
Pieces of mail handled in 1995 = [tex]1.8 \times 10^{11}[/tex]
Pieces of mail handled in 2010 = [tex]1.7 \times 10^{11}[/tex]
As it is clear that more pieces of mail were handled in 1995.
So, Pieces of mail handled in 1995 - Pieces of mail handled in 2010 = [tex](1.8 \times 10^{11}) -(1.7 \times 10^{11})[/tex]
= [tex]10^{11} \times (1.8 -1.7)[/tex]

b. 4b + 7w < 31
c. b + w <31
O d. b/4 + w/7 < 31
Answer:
The answer is a
Step-by-step explanation:
Becuase its right
Answer:
This is not an answer, just my though process:
Step-by-step explanation:
The fastest method would use all white squares:
96 white squares would take 13.7 days to complete and cost $115.20.
The cheapest method would use all blue squares:
96 blue squares would take 24 days to complete and cost $76.80.
As we can see, time is not the limiting step, the maximum of 96 squares is limiting.
An inequality equation should use the limiting step for it to be useful. Therefore, a, is most likely the answer.
A more concise answer would be: [tex]4b\leq 96[/tex]
A $20,000 business computer depreciates at a rate of 15% per year. What equation would model the value of the computer?
Answer:
[tex]A = 20,000(0.85)^t[/tex]
Step-by-step explanation:
We will use the formula for compound interest here
where [tex]A = p( 1 + r)^t[/tex]
A=future value for any sum
P=present value of the sum
r= yearly interest rate, it should be expressed in decimal
t=time period , it should be in years
______________________________
given in the problem
p = $20,000
r = 15% (in decimal 15/100 = 0.15)
t is the time for which equation is to be model to find future value p
since, rate is for depreciation we need to take negative value of rate as value for computer will decrease
thus
r = -0.15
using the above values in formula [tex]A = p( 1 + r)^t[/tex]
[tex]A = p( 1 + r)^t\\A = 20,000(1 - 0.15)^t\\A = 20,000(0.85)^t[/tex]
Thus, model equation for the value of the computer is [tex]A = 20,000(0.85)^t[/tex]
A car of mass 1200 kg, travelling at a steady speed of 15 m/s performs an emergency stop which takes 4.5 seconds. What braking force was applied by the driver and car to achieve this?
Answer:
4000 N
Step-by-step explanation:
this question should be in physics actually
m = 1200 kg
initial velocity = vo = 15 m/s
final velocity = vt = 0 because it stops
time needed = t = 4.5
so we can find the Force F by these step
first find deacceleration
vt = vo + at
0 = 15 + a(4.5)
15 = -4.5a
a = - 15/4.5 = - 10/3 = - 3.33 m/s²
F = m.a = 1200 . 10/3 = 4000 N

Answer:
P(AnB') = 1/7
P(A'UB') =5/7
P(B|A)=2/3
Step-by-step explanation:
from the venn diagram A and B shares 1,5
A = {1,4,5} this means sets found in A see the all values in first circle
B = {1,5,8,10,11} this means sets found in B see the all values in second circle
A'={8,10,11,12} this means sets NOT found in A see the all values NOT in first circle
B'={4,12} this means sets NOT found in B see the all values NOT in second circle
AnB={1,5} this means common sets shared by A and B
AuB = {1,4,5,8,10,11} this means sets in A or in B but do not write a number twice, example 1 is in A and B but you write it once.
AnB'={4} this means sets shared by A and B'
A'UB'={4,8,10,11,12} this means sets not in A' or not in B'
n=7 (count all the numbers you see)
I have written all the sets so we now solve for probabilities
P(A) = (numbers in A/All numbers (n) =3/7
P(B) = 5/7
P(AnB) = 2/7
P(AnB') = 1/7
P(A'UB') =5/7
P(B|A)=P(AnB) / P(A) = (2/7) ÷ (3/7) = (2/7)*(7/3) Reciprocal to change divide symbol to times symbol. Seven cancels out and you get 2/3.

The Schwartz family spent a total of $111.75 for Internet service for 3 months. Each
month they received $5.50 as a credit on the bill. Which equation and solution shows
the cost of their monthly Internet service before the credit?
3 (x + 5.50) = 111.75; the monthly Internet service is $31.75
3 (x - 5.50) = 111.75; the monthly Internet service is $42.75
1/3 (x - 5.50) = 111.75; the monthly Internet service is $42.75
1/3 (x + 5.50) = 111.75; the monthly Internet service is $31.75
Answer:
3 (x - 5.50) = 111.75
Step-by-step explanation:
They paid $111.75 for three months, that means they minus $5.50 every month which means a total of $16.5 for three months.
So you need use $111.75 plus the credit $16.5 for three months
111.75 + 16.5 = 128.25
Then use divide them by 3, (three months)
128.25 / 3 = 42.75
So they pay $42.75 per month before the credit.
