10[tex]x^{2}[/tex] -20x -12.5 inches
Step-by-step explanation:
Triangle Area Equation:
Area of triangle = [tex]\frac{1}{2} * base * height[/tex]
base = 10x + 5
height = 2x - 5
1/2 (10x + 5) (2x - 5)
= 1/2 (20[tex]x^{2}[/tex] - 50x + 10x - 25)
= 1/2 ( (20[tex]x^{2}[/tex] - 40x - 25)
= 10[tex]x^{2}[/tex] -20x -12.5 inches

Answers
Answer:
12 square units
Step-by-step explanation:
The area of a given figure is the measure of space occupied by the figure on a 2 dimensional plane.
Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height
From the given grid, the following can be observed for triangle STU.
base SU = 6 units
height = 4 units
Thus,
area of triangle STU = [tex]\frac{1}{2}[/tex] x base x height
= [tex]\frac{1}{2}[/tex] x 6 x 4
= 3 x 4
area of triangle STU = 12 square units
The required area of triangle STU is 12 square units.

Answer:
a. yes there is enough evidence

Step-by-step explanation:
H0: B2 >= 0
H1: B2 < 0
Alpha = 0.05
T critical is calculated to be -1.79
If t is less than -1.79 we reject the null hypothesis
Test statistic
S = √1107.01/15-3-1
= 10.032
T stat = -0.92 - 0/10.032√0.00081
= -3.222
-3.222 is less than -1.79
So we Reject the null hypothesis and conclude that enough evidence exists that B2<0
B. At 95% confidence
38.83 - 0.0092x1 - 0.92x2 + 11.56x3
= 38.83 - 0.0092x914 - 0.92x65 + 11.56x6
= 38.83 - 8.4088 - 59.8 + 69.36
= 39.98
39.98-2.2*28.55,39.85+2.2*28.55
= 39.98 - 62.81, 39.98 + 62.81
= -22.83, 102.79
A prism has a length of 8 meters, height of 14 meters, and width of 6 meters. What is the volume of the prism? m3
Answers
Answer:
672 m^3
Step-by-step explanation:
The formula to find the volume of a prism is V = l x w x h, where l is length, w is width, and h is height. You are given the length, width, and height in the problem so you just plug it into the formula.
V = 8 x 6 x 14
After multiplying all three numbers together, you should get the answer 672 m^3.

Answer:
160°
Step-by-step explanation:
Quadrilateral's angles add up to 360 degrees.
So:
x = fourth angle measure (unknown currently)
50° + 72° + 78° + x = 360°
200° + x = 360°

The graph of f(x) = 2^x + 4 shifts five units to the right when it is replaced with the graph of f(x) = 2^x - k. what is the value of k?
A. 5
B. -1
C. 1
D. 4
Answers
==============================================================
Work Shown:
I'm assuming you meant to write [tex]f(x) = 2^{x+4}[/tex] where all of the "x+4" is the exponent.
If we shift f(x) 5 units to the right to end up with g(x), then,
[tex]g(x) = f(x-5)\\\\g(x) = 2^{x-5+4}\\\\g(x) = 2^{x-1}\\\\[/tex]
In the second step, I replaced every copy of x with x-5 so that I could apply the translation of 5 units to the right.
The exponent for g(x) is x-1, which matches up with x-k. We see that k = 1.
a square has a perimeter of 48cm.the square is cut in half . the two halves are put together to make this shape . what is the perimeter of the new shape ?
Answers
Answer:
The length of each side is 12cm.
Explanation:
The perimeter of a square is calculated by the formula:
P=4a, where P=perimeter, and a=length of any side, all sides being equal in a square.
From the given data we write:
48=4a
Divide both sides by 4.
12=a
The length of each side is 12cm.

a.
Lewis has $879 more than Mary.
b.
Lewis has $179 more than Mary.
c.
Mary has $776 more than Lewis.
d.
Mary has $345 more than Lewis.
Answers
Answer:
lewis has $179 more than mary
Lewis has the greater total amount of money than Mary by $879
Given the following data:
Mary's principal = $3,700Mary's interest = 3.2% = 0.032Lewis's principal = $3,000Lewis's interest = 5.9% = 0.059Time = 15 years.To determine who has the greater total amount of money and by how much greater is it:
The formula for simple interest.Mathematically, simple interest is given by the formula:
[tex]S.I = PRT[/tex]
Where:
S.I is the simple interest.P is the principal or starting amount.R is the interest rate.T is the time measured in years.For Mary:[tex]S.I = 3700 \times 0.032 \times 15[/tex]
S.I = $1,776
For Lewis:[tex]S.I = 3000 \times 0.059 \times 15[/tex]
S.I = $2,655
Therefore, Lewis has the greater total amount of money.
Next, we would find the difference in their simple interest:
[tex]Difference = 2655-1776[/tex]
Difference = $879

Keiko, Dale, and Tony sent a total of 95 text messages during the weekend. Dale sent 7 fewer messages than Kelko. Tony sent 4 times as many messages as
Keiko. How many messages did they each send?
Answers
Answer:
Keiko sent 17 messages, Dale sent 10 messages, and Tony sent 68 messages
Step-by-step explanation:
Let x represent the number of messages that Keiko sent.
Since Dale sent 7 less than Keiko, his number can be represented by x - 7
Since Tony sent 4 times as many as Keiko, his number can be represented by 4x
Using these variables, create an equation:
(x) + (x - 7) + (4x) = 95
Add like terms and solve for x:
6x - 7 = 95
6x = 102
x = 17
So, Keiko sent 17 messages.
Subtract 7 from this to find how many Dale sent:
17 - 7
= 10
Multiply it by 4 to find how many Tony sent:
17(4)
= 68
So, Keiko sent 17 messages, Dale sent 10 messages, and Tony sent 68 messages

D. 18
Step-by-step explanation:
The polygon given is a 5-sided polygon (pentagon). Sum of all interior angles of a 5-sided polygon = (n - 2) * 180°
= (5 - 2) * 180 = 540°
Therefore:
95° + (7x - 4)° + (3x + 23)° + (9x - 6)° + 90° = 540°
Solve for x
95 + 7x - 4 + 3x + 23 + 9x - 6 + 90 = 540
Add like terms
198 + 19x = 540
19x = 540 - 198
19x = 342
x = 342/19
x = 18
