An investment of 4,000 earns 2% interest compounded annually. What will be value of the investment in 7 years
Start with your exponetial growth formula: y = a(1 + r)^t.
Now, a is going to be your initial amount, r is the rate, and t is the time.
So we have y = $4,000(1 + .02)^7.
Now simplify inside the parenthses first.
So we have y = $4,000(1.02)^7.
Simplifying further gives us y = $4,000(1.14868).
Now use a calculator to get y = $4,594.72
a sum of money was divided between two friends, karen and Natasha in the ratio 2:5. If Natasha received $120 more than karen, find the sum of money shared
Answer:
$600
Step-by-step explanation:
Let x be the total amount divided
Karen gets (2/7) x
Natasha gets (5/7) x
(5/7) x = (2/7) x + 210
Multiply both sides by 7
5x = 2x + 1470
3x = 1470
x = 490
Natasha gets (5/7) (490) = 350
Karen gets (2/7)(490) = 140
The difference in ration is 5 - 3 = 2. So divide 150 by 2 to get the amount for each part of the ratio which is 75. the total ration is 3 + 5 = 8. So to get the total original sum of money, multiply 75 and 8 which is $600. for each person just multiply 75 with their respective ratios. For A: 75 X 3 = $225. For B: 75 x 5= $375. To check that it is correct add 225 and 375, and you should get 600.
according to my calculations, the starting amount will be 600
Answer:
$280
Step-by-step explanation:
Ratio = 2 : 5
Karen's Share = 2x
Natasha's share = 5x
Natasha received $120 more than karen.
5x = 2x + 120
5x - 2x = 120
3x = 120
x = 120/3
x = 40
Karen's share = 2*40 = $ 80
Natasha's share = 5*40 = $ 200
Sum of money = 80 +200 = $ 280

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.48 before the discount, and they leave a 20% tip. If the tip applies to the cost of the meal before the discount, what is the total cost of the meal? Round your intermediate calculations and answer to the nearest cent.
how much does the meal cost?
Answer:
Step-by-step explanation:
c=t+p
c=0.2(78.84)+(1-0.15)(78.84)
c=0.2(78.84)+0.85(78.84)
c=15.768+67.015
c=15.77+67.02
c=$82.79

The volume of the square pyramid is ___ cubic centimeters.
Answer:
The volume of the square pyramid is 1,125 cubic centimeters
Step-by-step explanation:
From the diagram in the question, we have;
The height of the pyramid, h = 8 cm
The side length of the square base of the pyramid = 15 cm
The area of the square base of the pyramid, A = 15 cm × 15 cm = 225 cm²
The volume of a pyramid = 1/3 × A × h
Where;
A = The base area of the pyramid
h = The height of the pyramid
Therefore, the volume of the square pyramid, V = 1/3 × A × h
∴ V = 1/3 × 225 cm² × 15 cm = 1,125 cm³
The volume of the square pyramid, V = 1,125 cm³
Claire's backyard is in the shape of a rectangle and has a length of 19.5 feet. It cost her $945 to fence in the yard. If fencing costs $15 per foot, what is the width of Claire's backyard?
Answer:
Step-by-step explanation:
You need to know the formula for the perimeter of a rectangle. We won't use it right away, but it is pertinent information.
P = 2 ( l + w )
Now, we know that the fencing costs $15.00 per foot, and that the length is 19.50 feet.
We first need to find the price of one "length" side of the fence.
To do this, multiply 19.50 by 15.00
19.50 x 15.00 = 292.5
Next, we look at the perimeter equation to see what we can plug in where.
P = 2 ( l + w )
We can put in the total price of the fencing for the yard as P, and the amount of one length side of the fence as l.
945.00 = 2 ( 292.5 + w )
And now, we simply solve for w.
945.00 ÷ 2 = ( 2 ( 292.5 + w ) ) ÷ 2
472.5 = 292.5 + w
472.5 - 292.5 = 292.5 + w - 292.5
w = 180
It costs $180 for one "width" side of the fence.
To find out how many feet that is, we do the opposite of what we did with the length. Instead of multiplying by $15.00, we divide by $15.00
$180.00 ÷ $15.00 = 12
The width of Claire's backyard is 12 feet.

find the perimeter and area of rectangle JKLM. K(1,5) L(4,2) M(2,0) J(-1,3)
Answer:
perimeter: 10 units
area: 6 square units
Step-by-step explanation:
within the picture point J and point M seem to be 3 units are.
with this assumption, with can infer that both parallel sides are 3 units giving us 6 units for both sides
we can as well as tell that point J and point K seem to be 2 units apart.
with this info we can infer that both parallel sides will be the congruent lenght. which will add up to 4
thus giving us the equation for the area
6 + 4 = (10 units) for the perimeters
for that area we will then do 3 units by 2 units
(3 units for the assumed length and 2 units for the assumed width)
giving us the equation 3×2 = (6 square units)

Work out the size of angle x.
126°
43°
Answer:
the answer is 83°
Step-by-step explanation:
by the sum of iner and outer angle=180°
180-126= 54°
x=180-43+54
x=180-97
x=83°
The measure of angle x is 43°.
What is Triangle?
A triangle is a three sided polygon , which has three vertices.
Given that;
In triangle, The value of interior angles are 43° and x°.
And, An exterior angle is 126°.
Since, The sum of two interior angles is equal to the exterior angle of same triangle.
Hence, We can formulate;
43° + x = 126°
Subtract 43° both side;
43° + x - 43° = 126° - 43°
x = 83°
Thus, The measure of angle x is 43°.

4) 8² + ?² = 10²
Step-by-step explanation:
Because these are all right triangles, we can use the Pythagorean Theorem:
a² + b² = c²
Where c is the hypotenuse, the longest side of the triangle. It can be identified as being across from the right angle of the right triangle.
The legs are the two other sides of the triangle and they are interchangeable when placed in the Pythagorean Theorem.

Answer:
First option: 336
Step-by-step explanation:
To find the answer, separately solve for each of the shapes.
1. The base is the square so length times width is the formula:
12 x 12 = 144
144 is the area of the square
Next, find the 4 triangles which are congruent(the same).
Triangle area formula: Base x Height divided by 2.
So, the area of 1 triangle is 12 x 8 =96
96/2 = 48
Area =48
Because there are 4 triangles, do 48 x 4=192.
Finally, add the area together and you should get 192+144 =336 ft^2
Surface area = 336 ft^2

By solving the inequality 4.5a < 18, the answer will be
A. a<10
B. a<8
C. a<11
D. a<4
Answer: D plz mark me brainliest (tap the crown on the bottom right of an answer)
Step-by-step explanation: it has to be D because it can't be larger then 4
The inequality by solving the given equation of 4.5a < 18 will be a<4 . Then the correct option will be (D).
What is inequality?A difference between two values indicates whether one is smaller, larger, or otherwise not identical to the other.
Equations are not always balanced on both sides by using equal symbols in mathematics. Sometimes it can be about something like a not equal relationship, meaning that something is preferable to or lower than the next.
In another word, inequality is mean that if a number is not equal to the other number then it will be unequal and the constraint of this will make an inequality.
Given that
⇒ 4.5a < 18
⇒ a < 18/4.5
⇒ a<4 hence, the correct option is a <4.

A person's height is 5-ft 3-in. Their shadow has a length of 3-ft 6-in. If a nearby tree has a shadow of length 10-ft 4-in, what is the approximate height of the tree?
Answer: The height of tree = 15 ft. 6 inches
Step-by-step explanation:
Given: A person's height is 5-ft 3-in = [5 x (12 )+3 ] inches [ 1 ft= 12 inches]
= 63 inches
Their shadow has a length of 3-ft 6-in = [3 x 12+6] inches
= 42 inches
If a nearby tree has a shadow of length 10-ft 4-in = [10 x 12+4] inches
= 124 inches.
At the same time,
[tex]\dfrac{\text{Height of tree}}{\text{Height of person}}=\dfrac{\text{Length person's shadow}}{\text{Length of tree's shadow}}\\\\\dfrac{\text{Height of tree}}{63}=\dfrac{124}{42}\\\\\Rightarrow\ \text{Height of tree}=\dfrac{124}{42}\times63=186\ inches\\\\=\dfrac{186}{12}= 15.5 ft\ or\ 15 ft.\ 6\ inches.[/tex]
Hence, the height of tree = 15 ft. 6 inches
