Step-by-step explanation:

Answer:

there are 62 quarters and 48 dimes

Step-by-step explanation:

d + q = 110......d = 110 - q

0.10d + 0.25q = 20.30

0.10(110 - q) + 0.25q = 20.30

11 - 0.10q + 0.25q = 20.30

-0.10q + 0.25q = 20.30 - 11

0.15q = 9.30

q = 9.30/0.15

q = 62 <==== there are 62 quarters

d = 110 - q

d = 110 - 62

d = 48 <==== there are 48 dimes

Answer:

[tex]r=-3[/tex]

Step-by-step explanation:

The line that passes through the two points (6, -23) and (11, r) has a slope of 4.

We want to determine the missing value of r.

We can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (6, -23) be (x₁, y₁) and let (11, r) be (x₂, y₂). The final answer should be 4. Therefore:

[tex]\displaystyle \frac{r-(-23)}{11-6}=4[/tex]

Simplify and evaluate:

[tex]\displaystyle \frac{r+23}{5}=4[/tex]

Multiply both sides by 5:

[tex]r+23=20[/tex]

Therefore:

[tex]r=-3[/tex]

Answer:

A and D

Step-by-step explanation:

Answer:

A and D.

Step-by-step explanation:

The main property of rhombi is that they have all four congruent sides.

So the only two quadrilaterals with four congruent sides are A and D.

The angle sum of a triangle is 180 degrees. The measure of the angle GR is 160° then the correct option is B.

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

A ΔGRV is inscribed in a circle as shown in the figure below.

In ΔGRV, GR is congruent to GV.

Then the angle ∠V and ∠R are also equal.

The sum of the angle of the triangle is 180 degrees. Then angles ∠V and ∠R will be

∠V = ∠R = 80°

We know theorem

An arc of a circle subtends twice the angle it subtends anywhere on the circle's circumference at its center.

Then the measure of the angle GR will be

→ 2 × 80°

→ 160°

Step-by-step explanation:

The required value of h(1) for the function  h(x) = 5x -1 is 4.

Given that,
A polynomial function is given  h(x) = 5x -1, it value at x = 1 ios to be determined.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.

Here, according to the question
function  h(x) = 5x -1
at x = 1
h(1) = 5(1) - 1
      = 5 - 1
      = 4

Thus, the required value of h(1) for the function  h(x) = 5x -1 is 4.

Answer:

The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.

Step-by-step explanation:

Volume of a sphere:

The volume of a sphere is given by the following equation:

[tex]V = \frac{4\pi r^3}{3}[/tex]

In which r is the radius.

Implicit derivatives:

This question is solving by implicit derivatives. We derivate V and r, implicitly as function of t. So

[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]

The radius of a sphere is increasing at a rate of 4 mm/s.

This means that [tex]\frac{dr}{dt} = 4[/tex]

How fast is the volume increasing (in mm^3/s) when the diameter is 60 mm?

This is [tex]\frac{dV}{dt}[/tex] when [tex]r = \frac{d}{2} = \frac{60}{2} = 30[/tex]. So

[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]

[tex]\frac{dV}{dt} = 4\pi*(30)^2*4[/tex]

[tex]\frac{dV}{dt} = 1508[/tex]

The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.

Step-by-step explanation:

Answer:

[tex]s^2 = 0.9938[/tex] --- sample variance

[tex]s = 0.9969[/tex] --- sample standard deviation

Step-by-step explanation:

Given

[tex]\begin{array}{cc}{Heights} & {Frequency} & {116.1-120.0} & {38} & {120.1-124.0} & {24} &{124.1-128.0} & {28} & {128.1-132.0} & {43} & {132.1-136.0} & {29} \ \end{array}[/tex]

Required

Calculate the sample variance and sample standard deviation

First, we calculate the midpoint of each class:

[tex]\begin{array}{ccc}{Heights} & {Frequency} & {m} &{116.1-120.0} & {38} & {118.05}& {120.1-124.0} & {24}& {122.05} &{124.1-128.0} & {28} &{126.05}& {128.1-132.0} & {43} & {130.05} &{132.1-136.0} & {29} &{134.05}\ \end{array}[/tex]

The midpoints are calculated by taking the average of the class intervals.

For instance:

Class 116.1 to 120.0 has a midpoint of

[tex]m = \frac{1}{2}(116.1+120.0)[/tex]

[tex]m = \frac{1}{2}(236.1)[/tex]

[tex]m = 118.05[/tex]

The same approach is applied to other classes.

Next, is to calculate the mean:

[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]

In this case, it is:

[tex]\bar x = \frac{\sum fm}{\sum f}[/tex]

Where

[tex]m = midpoint[/tex]

So, we have:

[tex]\bar x = \frac{118.05*38+122.05*24+126.05*28+130.05*43+134.05*29}{38+24+28+43+29}[/tex]

[tex]\bar x = \frac{20424.10}{162}[/tex]

[tex]\bar x = 126.07[/tex]

The sample variance (s^2) is:

[tex]s^2 = \frac{\sum(m - \bar x)^2}{\sum f -1}[/tex]

This gives:

[tex]s^2 = \frac{(118.05-126.07)^2+(122.05-126.07)^2+(126.05-126.07)^2+(130.05-126.07)^2+(134.05-126.07)^2}{38+24+28+43+29-1}[/tex]

[tex]s^2 = \frac{160.002}{161}[/tex]

[tex]s^2 = 0.9938[/tex]

The sample standard deviation (s) is:

[tex]s = \sqrt{s^2[/tex]

[tex]s = \sqrt{0.9938[/tex]

[tex]s = 0.9969[/tex]
