Find the area of this figure
Step-by-step explanation:
well, I see one large rectangle (20×6), and 2 small triangles with their horizontal sides being (20-8-6)/2 = 3 m. and their vertical joined side being 10-6 = 4 m.
the total area is simply the sum of the rectangle and the 2 triangles.
the rectangle is
20×6 = 120 m²
each triangle is
4×3/2 = 2×3 = 6 m²
we have 2 of them, so their combined area is 2×6 = 12 m².
the total area is
120 + 12 = 132 m²
molly is 4 years younger than Heidi. In 3 years, Heidi will be twice as old as Molly. How old are they now
Answer:
Molly would be 1 years old.
Step-by-step explanation:
"In three years..."
(m+3) will be Molly's age then.
(h+3) will be Heidi's age then.
(h+3) = 2(m+3) :: given.
.
Subsitute what we know about m, which is it equal h-4.
.
(h+3) = 2(m+3)
(h+3) = 2m + 6
substitute m=h-4
(h+3) = 2(h-4) +6
h +3 = 2(h -4) +6
h +3 = 2h -8 +6
h +3 = 2h -2
h = 2h -8 +3
-h = -5
h = 5
Heidi is 5 years old now.
.
m = h-4
m = 5-4
m = 1
Molly is 1 years old now.

The $23 rd term in a certain geometric sequence is 16 and the $28th term in the sequence is 24. What is the $43 rd term?
Answer:
81
Step-by-step explanation:
Geometric sequence formula: [tex]a_n=ar^{n-1}[/tex]
Given:
[tex]a_{23}=ar^{22}=16[/tex][tex]a_{28}=ar^{27}=24[/tex]Find common ratio (r):
[tex]\begin{aligned}\implies \dfrac{a_{28}}{a_{23}} =\dfrac{ar^{27}}{ar^{22}} & =\dfrac{24}{16}\\ \implies r^5 & =\dfrac32\\ \implies r & = \sqrt[5]{\frac32} \end{aligned}[/tex]
Find initial term (a):
[tex]\implies ar^{22}=16[/tex]
[tex]\implies a(\sqrt[5]{\frac32} )^{22}=16[/tex]
[tex]\implies a(\frac32} )^{\frac{22}{5}}=16[/tex]
[tex]\implies a=\dfrac{16}{(\frac32)^{\frac{22}{5}}}[/tex]
Find the 43rd term:
[tex]\implies a_{43}=ar^{42}[/tex]
[tex]\implies a_{43}= \left(\dfrac{16}{(\frac32)^{\frac{22}{5}}}\right)(\sqrt[5]{\frac32} )^{42}[/tex]
[tex]\implies a_{43}=16 \cdot (\frac32)^{-\frac{22}{5}} \cdot (\frac32)^{\frac{42}{5}}[/tex]
[tex]\implies a_{43}=16 \cdot (\frac32)^4[/tex]
[tex]\implies a_{43}=16 \cdot \left(\dfrac{3^4}{2^4}\right)[/tex]
[tex]\implies a_{43}=16 \cdot \left(\dfrac{81}{16}\right)[/tex]
[tex]\implies a_{43}=81[/tex]
Daniel owns a synall business selling used books. He knows that in the last week 60
customers paid cash, 4 customers used a debit card, and 23 customers used a credit
card.
Based on these results, express the probability that the next customer will pay with a
credit card as a fraction in simplest form.
The probability that the next customer that comes into Daniel's business will pay with a credit card is 23 / 87.
What is the probability?Probability determines how likely it is that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that the next customer will pay with a credit card = number of people who paid with a credit card / total number of customers
23 / (23 + 60 + 4)

A theater group made appearances in two cities. The hotel charge before tax in the second city was $1000 lower than in the first. The tax in the first city was 3. 5% and the tax in the second city was 7%. The total hotel tax paid for the two cities was $455. How much was the hotel charger in each city before tax?
By solving a system of equations we will see that the charge on the first city was $5,000, and on the second city, $4,000.
How much was the hotel charge in each city?
Let's define the variables:
C₁ = charge in the first city.C₂ = charge on the second city.We know that:
C₂ = C₁ - $1000
And we also know that the total tax is $455, then we can write:
0.035*C₁ + 0.07*C₂ = $455
(this says that the total tax is $455)
So we have a system of equations:
C₂ = C₁ - $1000
0.035*C₁ + 0.07*C₂ = $455
We can replace the first one into the second to get:
0.035*C₁ + 0.07*(C₁ - $1000) = $455
0.105*C₁ - $70 = $455
C₁ = ($455 + $70)/0.105 = $5,000
And:
C₂ = C₁ - $1000 = $5,000 - $1,000 = $4,000
The charge in the first city is $5,000 and in the second city was $4,000.

. Which is a true statement about the transformation?
Answer: The orientation of the vertices was changed.
(x, y) ---> (x + 8, y - 3)
Step-by-step explanation: The triangle translation isn't on quadrant II, it's on quadrant I, so that answer choice isn't correct. The triangle ABC translated 8 units right and 3 units down, not 8 units left and 3 units up. Whenever you dilate, translate, rotate, or reflect triangles like ABC, the next triangle becomes A'B'C because it shows you that it's a transformation of the original triangle. The orientation of the figure didn't change, because it didn't change shape, rotation, or size, so the orientation wasn't affected at all, just the vertices.
The transformation is (x, y) ---> (x + 8, y - 3), because think of it like this. I already said that the triangle translated 8 units to the right, which means that the triangle is translating 8 units in the positive direction to the right. The triangle going 3 units down is in the negative direction, and that's why it's (x, y) ---> (x + 8, y -3).
Let me know if this is right! :)

Step-by-step explanation:
Surface area of a rectangular prism:
SA = 2(lw + lh + hw)
Given:
width (w) = 6 mlength (l) = 7 mheight (h) = 15 m⇒ SA = 2(7 · 6 + 7 · 15 + 15 · 6)
= 2(42 + 105 + 90)
= 2(237)
= 474 m²
Answer:
474 Sq m
Step-by-step explanation:
You have two sides that are 7m x 6m
(7*6)*2 = 84
You have two sides that are 15m x 6m
(15*6)*2 = 180
You have two sides that are 15m x 7m
(15*7)*2 = 210
84+180+210=474

Answer: (0, 9) or x = 0, y = 9
Step-by-step explanation:
The solution is the point of intersection.
Here, the lines intersect at the point (0, 9) in the format of (x, y) so we can pull out the answers x = 0 and y = 9.
Answer:
(0, 9)
Step-by-step explanation:
First we need to find the equations of each line!What I'd do is use the equation:gradient (m) = change in y ÷ change in xStarting with the left line, let's pick two coordinates that are on the lineI've picked: (-2, 5), (-3, 3)gradient (m) = (3 - 5) ÷ (-3 - -2) = -2 ÷ -1 = 2We can then use the equation y = mx + c (m is gradient)y = 2x + cWe know we have the point (-3, 3) on this line(-3, 3) = (x, y) so x = -3 and y = 3y = 2x + c3 = 2 × -3 + c3 = -6 + cc = 9Finally, we can say y = 2x + 9Doing the exact same steps for the other line...
y = -3x + 9Since we now have two y = ... equationsWe can say y = yWhich is the same as2x + 9 = -3x + 9We rearrange to find x...5x = 0x = 0That gives us the x-coordinate of where the lines meet (the solution of the system of equations)We can then pick either equation to find the y-coordinate:y = -3x + 9y = -3 × 0 + 9 = 9So the solution we have is at the point (0, 9)!A firm is considering projects s and l, whose cash flows are shown below. These projects are mutually exclusive, equally risky, and not repeatable. The ceo wants to use the irr criterion, while the cfo favors the npv method. You were hired to advise the firm on the best procedure. If the wrong decision criterion is used, how much potential value would the firm lose?.
If the wrong discion criterion is used, the potential lose in value for the firm is $209.07.
What is the correct decision criterion?
The correct decision criterion is the net present value. Net present value is the present value of after-tax cash flows from an investment less the amount invested. The internal rate of return is the discount rate that equates the after-tax cash flows from an investment to the amount invested
What is the loss in value if the wrong decision criteria is used?The net present vaue and the internal rate of return can be calculated using the financial calcuator.
Project S:
Cash flow in year 0 = $-1025Cash flow each year from year 1 to 4 = $380I = 6%
NPV = 291.74
IRR = 17.86%
Project I:
Cash flow in year 0 = $-2150
Cash flow each year from year 1 to 4 = 765
I = 6%
NPV = 500.81
IRR = 15.78%
If the wrong criteria is used, Project S would be chosen.
