Answer:

791.

prime numbers less than 80 are:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79

sum of these numbers are

2+3+5+7+11+13+17+19+23+29+31+37+41+43+47+53+59+61+67+71+73+79

= 791

Answer/Step-by-step explanation:

✔️Slope (m) using the two points (2, 4.58) and (5, 4.28):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4.28 - 4.58}{5 - 2} = \frac{-0.3}{3} = -0.1 [/tex]

Slope (m) = -0.1

✔️Initial Value = y-intercept = b

To find b, substitute x = 2, y = 4.58, and m = -0.1 into y = mx + b.

(Note: y is P(t) and x is t).

Thus:

4.58 = (-0.1)(2) + b

4.58 = -0.2 + b

Add 0.2 to both sides

4.58 + 0.2 = b

4.78 = b

b = 4.78

Initial value = 4.78

✔️Equation for the linear function:

Substitute b = 4.78, and m = -0.1 into P(t) = mt + b

Thus the equation would be:

P(t) = -0.1t + 4.78

✔️The y-intercept = initial value = 4.78

✔️The x-intercept = the value of t when P(t) = 0.

To get this, substitute P(t) = 0 into P(t) = -0.1t + 4.78.

Thus:

0 = -0.1t + 4.78

Add 0.1t to each side

0.1t = 4.78

Divide both sides by 0.1

t = 47.8

x-intercept = 47.8

Answer:

$78.01

Step-by-step explanation:

solve the equation 56(1+.037÷4)^4×9

ends up being 56(1.00925)^36

56(1.3930133899)

=78.0087

The total value of the annuity in 9 years is: $78.00

We have the following information available from the question is:

He buys an annuity with a quarterly payment of $56 that pays 3.7 interest, compounded quarterly.

Payments will be made at the end of each quarter.

We have to find the total value of the annuity in 9 years.

Now, According to the question:

The total value of the annuity in 9 years :

The equation will be :

[tex]= > 56(1+ \frac{3.7}{4} )^4^(^9^)[/tex]

=>56(1.3930)

=$78.00

Given that,

A group of workers can plant 2/5 acres in 7/8 days.

To find,

The unit rate in acres/day.

Solution,

To find unit rate, divide acres and days as follows:

[tex]R=\dfrac{\dfrac{2}{5}}{\dfrac{7}{8}}\ \text{acres/days}\\\\=\dfrac{2}{5}\times \dfrac{8}{7}\\\\=0.45\ \text{acres/days}[/tex]

So, the unit rate is 0.45 acres/days.

The coordinates of X¹ will be (6,-2), if the rectangle was rotated 90° clockwise about the origin.

Given that, rectangle WXYZ has coordinates at W(2, 2), X(2, 6), Y(4, 6), and Z(4, 2) respectively. We have to calculate the coordinates of X¹ when the rectangle was rotated 90° clockwise about the origin.

Rotation generally helps us to align the figures in the direction along with a fixed point. To rotate the figure 90 degrees clockwise about a point, every point(x,y) will rotate to (y, -x). So, (y,-x) will be the rotation of the coordinates about 90° clockwise about the point.

So, we have to calculate the coordinate after rotation of X(2, 6). Let's suppose after rotation X changes to X¹ then, we have

X(2, 6)→X¹(6,-2) when the rectangle was rotated 90° clockwise about the origin.

Therefore, (6,-2) is the required answer.

The model for the relationship between the number of $0.20 price decrease, x, to the amount of money earned, E, is presented by the following equation;

Please find attached the values of the model in the attached table and graph of the model.

Let x represent the number of $0.20 price decrease and let E represent the total amount earned (the revenue), we have the following revenue equation;

However;

When the number of cars washed = (450 + 50•x)

The price to wash one car = (5 - 0.2•x)

Therefore;

Which gives the following equation;

Please find the attached table and graph created using the above equation for the amount earned per year.

From the graph, the maximum amount is earned when the price is reduced by $0.20, eight times to give;

Answer:

<4 = 81

Step-by-step explanation:

we know that all the interior angles of a triangle will equal 180

so <1 + <2 + <3 = 180

we know that <4 is the exterior angle to <3

the exterior angle is equal to the angles opposite to its interior

<3 is the interior angle to <4

<1 and <2 are the angles opposite to <3

so <4 = <1 + <2

<4 = 42 + 39

<4 = 81

Answer:

40%

Step-by-step explanation:

A percent is;

[tex]\frac{part}{whole} = \frac{x}{100}[/tex]

It is given that Jolie the 75 dodgeballs in total, hence the whole is 75. It is also given that 30 of the dodgeballs hit the target, so the part is 30. Now all one has to do is solve for "x".

[tex]\frac{30}{75} = \frac{x}{100}[/tex]

Simplify [tex]\frac{30}{75}[/tex] by dividing the numerator and denominator by 15.

[tex]\frac{2}{5}[/tex]

Now the equation is;

[tex]\frac{2}{5}=\frac{x}{100}[/tex]

Typically, one would solve a proportion by doing cross products, but in this case, it is easier to think about it intuitively. Since 5 is a factor of 100 (5 * 20 = 100), then all one has to do is multiply [tex]\frac{2}{5}[/tex] by 20 to get the answer (on the numerator).

x = 40

Answer:
