A savings bond currently made Jamar $2,112.64 worth of interest in 7 years. If the investment gained 5.5% annual simple interest each year, approximately how much was the bond originally bought for?
Answer:
$5487.38
Step-by-step explanation:
Given that:
Interest currently made = $2112.64
Time = 7 years
Rate of interest = 5.5% annual
To find:
The price for which the bond was originally bought ?
Solution:
We need to find nothing but the principal amount.
First of all, let us have a look at the formula for Simple Interest.
[tex]Simple\ Interest = \dfrac{PRT}{100}[/tex]
Where [tex]P[/tex] is the principal amount
[tex]R[/tex] is the Rate of Interest
[tex]T[/tex] is the time for which the investment is made
Let us put the given values in the formula:
[tex]2112.64 = \dfrac{P\times 5.5\times 7}{100}\\\Rightarrow P =\dfrac{2112.64\times 100}{5.5\times 7}\\\Rightarrow P =\dfrac{211264}{38.5} \\\Rightarrow \bold{P =\$5487.38}[/tex]

Answer:
I think it’s 10:)
Step-by-step explanation:
Expression A: 3(x + 2) Expression B: 3x + 6....... Which statement does not show that these expressions are equivalent? O A. Substituting any value of x makes the expressions equivalent B. The expressions name the same number regardless of the value of x. O C. Both expressions involve addition. O D. 3(x+2) can be rewritten as 3x + 6 using the distributive property. SUBMIT E PREVIOUS
Answer:
D. 3(x+2) can be rewritten as 3x + 6 using the distributive property
Step-by-step explanation:
Given
[tex]3(x + 2) = 3x + 6[/tex]
Required
Explain
From the list of given options, option D answers the question.
This is because, the expression above involves distributive property and only option D correctly states that.
A distributive property is:
[tex]a*(b + c) = a*b + a * c[/tex]
In this case:
[tex]a = 3[/tex] [tex]b = x[/tex] and [tex]c = 2[/tex]
So:
[tex]a*(b + c) = a*b + a * c[/tex]
Substitute values for a, b and c
[tex]3*(x + 2) = 3 * x + 3 * 2[/tex]
[tex]3(x + 2) = 3x + 6[/tex]
Answer:
C. Both expressions involve addition.

The perimeter of a rectangle is 50 inches. The length of the rectangle is 10 inches. Which
method can be used to find w, the width of the rectangle?
Divide 50 by 2 and then add 10.
Solve for w in the equation 2 (W + 10) = 50.
Solve for w in the equation 2w + 10 = 50.
Divide 50 by the product of 10 and 2.
Answer:
B. Solve for w in the equation 2 (W + 10) = 50Step-by-step explanation:
P = 50 inl = 10 inw = ?Perimeter formula
P = 2(l + w)Solving for w
50 = 2(10 + w)10 + w = 50/210 + w = 25w = 25 - 10w = 15Option B is correct

The weight of the baby at birth is 8 pounds.
Given,
The weight, in pounds, of a newborn baby tt months after birth, can be modeled by W.
The table below has select values showing the linear relationship between
t and W.
We need to determine the weight of the baby at birth.
The table is given as:
t w1 10
4.5 17
9 26
How do we read the tables given?The table has two columns and it always has a relationship between them depending on the question.
Example:
Miles. Hours
2. 3
6. 9
8. 12
Here we see that every 1-5 hours there's a mile increase.
We have,
W = weight of the baby
t = number of months.
From the table:
The baby weight-
At 1 month = 10
At 4.5 months = 17
At 9 months = 26
We see that,
In,
(4.5 - 1) = 3.5 months there is an increase of (17 - 10) = 7 pounds.
So we can write it as:
3.5 months = 7 pounds
1 month = 7/3.5
1 month = 70/35 = 10/5 = 2 pounds
This means in after every month there is an increase of 2 pounds.
We have,
1In the first month, the weight of the baby is 10 pounds.
And every month there is an increase of 2 pounds.
So,
The weight of the baby at birth is:
= 10 - 2
= 8 pounds
Thus the weight of the baby at birth is 8 pounds.

12. F(x) = 4x squared
Answer:
y-intercept: [tex]y=0[/tex]
axis of symmetry: [tex]x=0[/tex]
vertex: [tex](0,0)[/tex]
Step-by-step explanation:
To find the y-intercept, set x = 0 and solve for y.
I am assuming f(x) = y
[tex]y=4x^2[/tex]
[tex]y=4(0)^2[/tex]
[tex]y=0[/tex]
The y-intercept of the equation is y = 0.
Now, for the axis of symmetry, you need the equation [tex]x=\frac{-b}{2a}[/tex]
In an equation.. [tex]y=ax^2+bx+c[/tex]
In this case, there is only an a, so plug in the values into the equation.
[tex]x=\frac{0}{2(4)}[/tex]
[tex]x=0[/tex]
The axis of symmetry is x = 0.
To find the vertex, change the format of the equation from standard form to vertex form.
Vertex form: [tex]y=a(x-h)^2+k[/tex]
The vertex is [tex](h,k)[/tex]
[tex]y=4x^2 = 4(x+0)^2+0[/tex]
[tex](h,k)=(0,0)[/tex]
The vertex in this case is (0,0).

A car dealership sold 84 cars in April. The dealership wants to increase the number of cars sold by 25% in May. How many cars will the dealership need to sell to reach their goal?
Answer:
The car dealer must sell 105 cars in May to reach his goal.
Step-by-step explanation:
Given that the car dealer sold 84 cars in April, and wants to increase his May sales by 25%, to determine the number of cars he must sell to reach his goal it is necessary to perform the following calculation:
84 + (84 x 0.25) = X
84 + 21 = X
105 = X
Therefore, the car dealer must sell 105 cars in May to reach his goal.

Lola scored 21 out of 27 points on a mid-unit quiz in math. Later she scored 66 points out of 80 on the unit test.
Did she increase or decrease the percent she scored from the quiz to the test?
Answer:
Increased on the test more than the quiz
Step-by-step explanation:
If we do 21/27, we get 0.77777777777, as a percent, 0.77.
Then we do 66/80, and get 0.825, as a percent, 0.82.

How do you do this question?
Answer:
S(50) = 0
Step-by-step explanation:
The initial condition is S(0) = 0, so start at the origin. The slope there is approximately 1. So as t increases by a small amount, S increases by the same amount. Continuing this logic, we end up tracing the vector field until we get to t=50, where S is approximately 0.
Each little tickmark is a slope value telling you which direction to go. If you place yourself at the origin (0,0) then the tick mark here tells us to go roughly in the northeast direction. As you step forward to the northeast just a tiny bit, the slope value changes to aim more toward the east (rather than north). For more information, check out Euler's method. Specifically it's Euler's method dealing with slope fields.
The diagram below shows what could be each step of this process. Each red dot is a stepping stone, so to speak, going from (0,0) to (50,0). This is an approximation. Without the actual function F(t, S), it's hard to say where exactly S(50) is located. But S(50) = 0 is a fairly good guess I think. MathPhys has a great diagram showing what could be the solution for S(t) given the initial condition S(0) = 0. Note how they drew a curve through all of the red points I've marked.

Answer:
first answer is 9.84
Step-by-step explanation:
9.84 is the square root of 97, rounded to the nearest hundredth.
the legs measure 9 x 9 and 4 x 4 = 81 and 16.
81 + 16 = 97, so your answer is the square root of 27, which rounded to the nearest hundredth, equals 9.84. Rounding towards the nearest whole, 10 would be your best bet.
