Answer:
618.4 unit^2.
Step-by-step explanation:
We have 6 surfaces ( 3 pairs of equal area) so it is:
2 * 8.6*10 + 2 * 8.6*12 + 2 * 10*12
= 2 * 86 + 24*8.6 + 2 * 120
= 618.4.

To the nearest cent, how much interest will she earn in 3 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
1180.12
Step-by-step explanation:
p= 4000
r = 9% =0.09
t =3
plug in into B = p(1 + r)^t
B = 4000(1 + 0.09)^3
B = 4000(1.09)^3
B =5180.116 round to the 2 decimals
B = 5180.12
make the difference between B, the balance (final amount) and p, the principal (starting amount) = 5180.12-4000 =1180.12

C. x = 6Step-by-step explanation
since we have a right triangle then we can apply the Pythagorean theorem:
x² + 8² =10²
⇒ x² = 10² - 8²
⇒ x² = 36
⇒ x² = 6²
⇒ x = 6 (because x is positive)

Solve for xxx. Write the smaller solution first, and the larger solution second. Round to two decimal places. (x + 3)^2 - 3 = 0
Answer:
x=-4.73 and -1.26
Step-by-step explanation:
We need to solve the given equation for x.
[tex](x + 3)^2 - 3 =0[/tex]
Solving the above equation using formula (a+b)² =a²+2ab+b²
[tex](x + 3)^2 - 3 =0\\\\x^2+9+6x-3=0\\\\x^2+6x+6=0[/tex]
It is a quadratic equation.
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
We have, a = 1, b = 6 and c = 6
[tex]x=\dfrac{-6\pm \sqrt{(6)^2-4\times 1\times 6} }{2\times 1}\\\\x=\dfrac{-6+\sqrt{(6)^{2}-4\times1\times6}}{2\times1},\dfrac{-6-\sqrt{(6)^{2}-4\times1\times6}}{2\times1}\\\\x=-1.267, -4.73[/tex]
So, the values of x are -4.73 and -1.26

The bar graph in the following graphic represents fictional net exports in billions of dollars for five countries. Net exports are obtained by subtracting total imports from total exports; a negative net export means the country imported more goods than it exported.
What is the sum of net exports for Germany and China ?
a.
-80 billion dollars
c.
90 billion dollars
b.
180 billion dollars
d.
150 billion dollars
Answer:
d.) 150 billion dollars
Step-by-step explanation:
As per the given bar graph, we can draw the following conclusions:
Net exports for United States = ~ -110 Billion Dollars (It means import of 110 Billion Dollars)
Net exports for Denmark = ~ -30 Billion Dollars (It means import of 30 Billion Dollars)
Net exports for China = ~ 115 Billion Dollars
Net exports for Germany = ~ 35 Billion Dollars
We have to find the sum of net exports of Germany and China:
[tex]\Rightarrow[/tex] 35 + 115 = 150 Billion Dollars.
Hence, correct answer is d. 150 Billion Dollars.
Answer: d
Step-by-step explanation:

Find AB
picture is attached
Answer: AB = 15 units long.
Step-by-step explanation:
The triangles are identical.
You can infer this from both triangles sharing the side of BD and AD and CD marked as equal in length.
When triangles are identical, all three sides and angles are identical in length and measure, respectively.
Knowing this, we can set the sides of "5x" and "4x + 3" equal to each other in an equation to solve for x:
5x = 4x + 3
x = 3
When x equals 3, multiply x by 5 to find the side length of AB.
AB = 15 units long.

Answer:
h = 2.5 cm
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular end, h is the length of prism )
Here V = 35 and h = 7, thus
7A = 35 ( divide both sides by 7 )
A = 5 cm²
Thus
A = [tex]\frac{1}{2}[/tex] × 4 × h = 5
2h = 5 ( divide both sides by 2 )
h = 2.5 cm

Which factorization is equivalent to this expression?
30x + 70
Answer 10(3x+7)
Hopes this helps.
Answer:
[tex]10(3x+7)[/tex]
Step-by-step explanation:
we have the expression:
[tex]30x + 70[/tex]
To factor this expression we need to indentify the components that are common in both terms.
At first glance there is nothing in common, but we can notice that 30 and 70 are multiples of 10, that is:
[tex]10*3=30\\10*7=70[/tex]
so we can substitute this into the expression:
[tex]10*3x+10*7[/tex]
and now that we have the common term (the number 10) we can factorize it, that is, take out the common term and include a parentheses:
[tex]10(3x+7)[/tex]
Answer:
The Answer is 10(3x+7)

In a class of 40 students, 8 are in the drama club and 12 are in the art club. If a student is selected at random, what is the probability that the selected student is...
1
...in the drama club?
1
...in the art club?
Answer:
20 percent for drama club
30 percent for art club
Answer:
p(drama club) = 1/5
p(art club) = 3/10
Step-by-step explanation:
Total number of students = 40
Number of students in drama club = 8
p(drama club) = 8/40 = 1/5
Number of students in art club = 12
p(art club) = 12/40 = 3/10
Find the solution to the system of equations.
Answer:
3x - 2 = -5x + 6
8x = 8
x = 1
y = 3 (1) -2
y = 3 - 2
y = 1
Step-by-step explanation:
Answer:
x = 1 and y = 1
Step-by-step explanation:
We want to find the solution. Our equations are:
y = -5x + 6
y = 3x - 2
Let's set these two equations equal to each other:
-5x + 6 = 3x - 2
8x = 8
x = 1
Substitute this back into any of the two equations to solve for y:
y = 3x - 2
y = 3 * 1 - 2 = 3 - 2 = 1
Thus, the answer is (1, 1), or x = 1 and y = 1.

At a concession stand, a pickle and two bags of chips costs a total of $3.25. Three pickles and four bags of chips costs a total of $7.25. To determine the cost of one pickle, Kevin is writing a system of equations. His first equation is shown below. Which of the following could be the second equation in his system of equations?
Answer:
A bag of chips costs $1
A pickle costs $1.25
Step-by-step explanation:
P + 2c = 3.25 Start with these two equations
3p + 4c = 7.25
p = -2c + 3.25 Solve for one variable
3(-2c +3.25) + 4c = 7.25 Substitute
-6c + 9.75 + 4c = 7.25
-2c = -2
c = 1
p + 2(1) = 3.25 Substitute
p + 2 = 3.25
p = 1.25
You randomly draw a marble out of a bag that contains 202020 total marbles. 121212 of the marbles in the bag are blue. What is \text{P(draw a blue marble})P(draw a blue marble)start text, P, left parenthesis, d, r, a, w, space, a, space, b, l, u, e, space, m, a, r, b, l, e, end text, right parenthesis? If necessary, round your answer to 222 decimal places.
Answer:
0.60Step-by-step explanation:
Probability is defined as the likelihood or chance that an event will occur. IT is expreesed as shown;
Probability = Expected outcome of event/total outcome of event
If a bag contains 20 total marbles, then the total outcome of event is 20.
If 12 blue marbles are selected from the bag, the expected outcome of event will be 12.
Probability of drawing a blue marble P(draw a blue marble)= 12/20

PLEASE....HELP !!! WRITE PROPERLY PLEASE... CORRECT ANSWER PLSS...
Answer:
see below
Step-by-step explanation:
V = l*w*h
1. V = l*w*h
96 = 6*3.2 h
96 = 19.2h
Divide each side by 19.2
96/19.2 =h
h = 5
2. V = l*w*h
22 = l*2 *1.1
22 = 2.2l
Divide each side by 2.2
22/2.2 =l
10 = l
3. V = l*w*h
120 = 12*w *4
120 = 48w
Divide each side by 48
120/48 = w
w =2.5
