James has a bag 77 of nickels and dimes. The total value of coins is $6.60. How many dimes does James have?

Answer:

11 yards

Step-by-step explanation:

The volume of a cone formula is:

[tex]V=\frac{1}{3}\pi r^2 h[/tex]

Where V is the volume,

r is the radius (half of diameter)

h is the height

Given,

h = 15

V = 475.17

We find the radius (r) first by substituting given values:

[tex]V=\frac{1}{3}\pi r^2 h\\475.17=\frac{1}{3}\pi r^2 (15)\\475.17=5\pi r^2\\r^2=30.25\\r=5.5[/tex]

The radius (r) is 5.5 yards

We need the diameter, which is DOUBLE THE RADIUS, so diameter would be:

Diameter = 5.5 * 2 = 11 yards

Answer:

Katherine invested $12,000

Step-by-step explanation:

Use formula

[tex]I=P\cdot r\cdot t,[/tex]

where

I = interest,

P = principal,

r = rate (as decimal),

t = time (in years).

In your case,

t = 1 year,

r = 0.06 (or 6%)

P + I =$12,720, thus

[tex]12,720-P=P\cdot 0.06\cdot 1\\ \\12,720-P=0.06P\\ \\12,720=P+0.06P\\ \\1.06P=12,720\\ \\P=\dfrac{12,720}{1.06}\\ \\P=\$12,000\\ \\I=\$12,720-\$12,000=\$720[/tex]

Answer:

m(the slope) = -2

Step-by-step explanation:

First, you want to use the slope formula. This can be written as (Y[subscript2]-Y[subscript1])/(X[subscript2]-X[subscript1]). This may seem a bit confusing but I hope it will make sense to you. The subscripts basically mean which Y value or X value you are taking. In this case, you could rewrite the equation as this: (18-8)/(1-6). The 18 is the Y value of the second point, so it is Y[subscript2]. Now all you need to do is simplify the equation.

(18-8)/(1-6)

Answer:

-12 feet per second

Step-by-step explanation:

average rate of change over [0.75, 1.25] = [tex]\frac{f(1.25) - f(0.75)}{1.25 - 0.75}[/tex]

f(1.25) - f(0.75) = 4 - 10 = -6

1.25 - 0.75 = 0.5

[tex]\frac{f(1.25) - f(0.75)}{1.25 - 0.75}[/tex] = [tex]\frac{-6}{0.5}[/tex] = -12

The average rate of change of the function f(t) over the interval [0.75, 1.25] is -12 feet per second.

We have,

To find the average rate of change of the function f(t) over the interval [0.75, 1.25], you can use the following formula:

Average Rate of Change = [f(1.25) - f(0.75)] / (1.25 - 0.75)

Calculate f(1.25):

f(1.25) = -16(1.25)^2 + 20(1.25) + 4

Calculate f(0.75):

f(0.75) = -16(0.75)^2 + 20(0.75) + 4

Plug these values into the formula:

Average Rate of Change = [f(1.25) - f(0.75)] / (1.25 - 0.75)

Calculate the numerator:

Average Rate of Change = [(-16(1.25)^2 + 20(1.25) + 4) - (-16(0.75)^2 + 20(0.75) + 4)] / (1.25 - 0.75)

Simplify the numerator:

Average Rate of Change = [-25 + 25 + 4 - (-9 + 15 + 4)] / (1.25 - 0.75)

Further, simplify:

Average Rate of Change = (4 - (-9 + 15 + 4)) / (1.25 - 0.75)

Continue simplifying:

Average Rate of Change = (4 - 10) / (1.25 - 0.75)

Calculate the final result:

Average Rate of Change = (-6) / (0.5)

Average Rate of Change = -12 feet per second

Thus,

The average rate of change of the function f(t) over the interval [0.75, 1.25] is -12 feet per second.

Answer:

C) y+6=3/2(x-2)

Step-by-step explanation:

y-y1=m(x-x1)

m=slope & (x1, y1) is a point on the line

m=(y2-y1)/(x2-x1)

m=(-3-(-6))/(4-2)

m=(-3+6)/2

m=3/2

y-(-6)=3/2(x-2)

y+6=3/2(x-2)

Option 3

The point slope form of the given points (2, -6) and (4, -3) is [tex]y+6=\frac{3}{2}(x-2)[/tex]

Given that two points are (2, -6) and (4, -3)

We have to find the point slope form

The point-slope of the line is given as:

[tex]y - y_1 = m(x - x_1)[/tex]

Where m is the slope of the given line.

So now to write the given points in point intercept form we need to find the slope, m

The slope of line is given as:

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]\text { Here } x_{1}=2 ; y_{1}=-6 ; x_{2}=4 ; y_{2}=-3[/tex]

Plugging in the values, we get

[tex]m=\frac{-3-(-6)}{4-2}=\frac{3}{2}[/tex]

So, the slope of the given line is [tex]\frac{3}{2}[/tex]

Now, we need to find the point slope form. For that purpose we can use either of the points, but since in the answer options they have used the 1st point we will do so too.

Therefore, the point slope form is:

[tex]\begin{array}{l}{y-(-6)=\frac{3}{2}(x-2)} \\\\ {y+6=\frac{3}{2}(x-2)}\end{array}[/tex]

From the given options we can see that the correct answer is option 3.

Dustin spends $13.6125 on going to work daily. It is 0.11 dollars per mile

Step-by-step explanation:

we have to caalculate the distance between Dustin's home and work

So

Given

Speed =s = 55 miles per hour

Time = t = 2 hours and 15 minutes

Converting time into fraction

Time = 2.25 hours

We know that

[tex]s = \frac{d}{t}\\d = s * t\\d = 55 * 2.25\\d = 123.75\ miles[/tex]

So the distance is 123.75 miles

The car travels 25 miles per gallon

We have to calculate the total number of gallon first

So,

[tex]No.\ of\ gallons = \frac{Miles}{Miles\ per\ gallon}\\=\frac{123.75}{25}\\=4.95\ gallons[/tex]

So the total amount is:

[tex]2.75*4.95\\= 13.6125\ dollars[/tex]

Total amount is $13.6125. Dividing it by total distance will give us the cost of each mile

So,[tex]Cost\ of\ mile = \frac{Total\ amount}{Distance}\\= \frac{13.6125}{123.75}\\=0.11\ dollars[/tex]

Step-by-step explanation:

f(x) = 4x⁴ − 21x³ − 46x² + 219x + 180

Plug in the zero of each binomial.  If it's also a zero of f(x), then that binomial is a factor of f(x).

f(-4) = 936

f(-3) = 0

f(5) = 0

f(-3/4) = 0

The binomial (x + 4) is not the factor of the polynomial. Then the correct option is A.

The algebraic factors with exactly two terms are known as binomial components. Although binomials are simple to solve and their roots are identical to those of polynomials, binomial factors are intriguing.

The polynomial is given below.

⇒ 4x⁴ – 21x³ – 46x² + 219x + 180

Let's check all the factors.

If the factor does not satisfy the polynomial, then the binomial is a factor of the polynomial.

For x + 4 = 0, then we have

The value of the polynomial at x = -4, will be

⇒ 4(-4)⁴ – 21(-4)³ – 46(-4)² + 219(-4) + 180

⇒ 4(256) – 21(-64) – 46(16) + 219(-4) + 180

⇒ 1024 + 1344 – 736 – 876 + 180

⇒ 2548 – 1612

⇒ 936

Thus, the binomial (x + 4) is not the factor of the polynomial.

Then the correct option is A.

4/9

Step-by-step explanation:

(4/9)/(7/9) is equal to (4/9)*(9/7) because "keep change flip." So we keep the first number, change division into multiplication, and flip 4/9 (basically find the reciprocal) and that is 9/4. Thus,  (4/9)*(9/7) is equal to 4/9 because the 7's cancel.

I hope this helped!

Answer: 4/7

Step-by-step explanation: In this problem, we have 4/9 ÷ 7/9. Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division to multiplication and flip the second fraction.

So here, 4/9 divided by 7/9 can be rewritten as 4/9 × 9/7.

Now we are simply multiplying fractions.

To multiply fractions, we multiply across the numerators and multiply across the denominators.

Notice however that 36/63 is not in lowest terms so we divide both the numerator and denominator by 9 and we get the equivalent fraction 4/7.

Because you multiply 5 times 2288

Leo has 2574 red marbles.

Let's say that the number of blue marbles Leo has is x. According to the given information, Leo has 9 times as many red marbles as blue marbles. So the number of red marbles Leo has is 9x.

It is also given that he has 2288 more red marbles than blue marbles, which means 9x = x + 2288.

Simplifying the equation, we can subtract x from both sides: 8x = 2288. Dividing both sides by 8, we find that x = 286.

Therefore, Leo has 9 times 286 red marbles, which equals 2574 red marbles.

By proving that triangles DEA and EFB are congruent due to the Side-Angle-Side postulate and demonstrating that AE is parallel to FB as well as AD parallel to BC, we can conclude that EABC is a parallelogram.

To prove that quadrilateral EABC is a parallelogram, we can use the properties of triangles and the definition of a parallelogram. According to the given information, E is the midpoint of DA and F is the midpoint of DB. Additionally, we know that E, F, and C are collinear and that FC is congruent to EF.

Leveraging these pieces of information, we observe that triangle DEA is congruent to triangle EFB because they have a side (EF or DE), an angle (at point E, since DE is an extension of EF), and another side (EA or FB, which are halves of DA and DB, respectively) in common (Side-Angle-Side postulate).

Since the two triangles are congruent, angle DEA is congruent to angle EFB, and angle DAE is congruent to angle FEB. These congruent angles imply that line AE is parallel to line BF. Since E and F are midpoints, AE is half of DA and BF is half of DB. If we continue the line AE to meet CD at point A and the line BF to meet CD at point B, EA will be parallel to FB, and AD will be parallel to BC, meeting the definition of a parallelogram.

EABC is a parallelogram because opposite sides are parallel and equal due to the Midpoint Theorem.

Given:

E - midpoint of DA

F - midpoint of DB

E, F, C collinear, FC ≅ EF

To Prove: EABC is a parallelogram.

Proof:

1. By the Midpoint Theorem, EF || AB and EF = 1/2 * AB. (Midpoint Theorem)

2. Since E, F, C are collinear and FC ≅ EF, EC bisects EF at C. Therefore, AB || EC. (Definition of a parallelogram)

3. Since E is the midpoint of DA and C is the midpoint of EF, EC = 1/2 * DA. Since DA = AB, EC = 1/2 * AB. Similarly, EF = 1/2 * AB. Hence, EC = EF. Therefore, EA || BC. (Midpoint Theorem)

4. Since E is the midpoint of DA and C is the midpoint of EF, EC = 1/2 * DA. Since DA = BC, EC = 1/2 * BC. Similarly, EF = 1/2 * BC. Hence, EC = EF. Therefore, EB ≅ AC. (Midpoint Theorem)

Therefore, EABC is a parallelogram.
