Answer:

The smaller angle is 12 and the larger angle is 168

Step-by-step explanation:

Let call the measure of the random angle a. There is a angle that is 14 times of that and supplementary to that the random angle. So that is represented by

[tex]14a[/tex]

Supplementary Angles add up to 180 degrees so let set up an equation

[tex]a + 14a = 180[/tex]

which equal after you combine like with like

[tex]15a = 180[/tex]

Divide 15 by both sides and a=12 and the so smaller angle is 12 and the larger angle is 168

Answer: 5 + 5w

Step-by-step explanation:

We can use the variable x to describe each additional hour, although the vairable can be substituted for any other vairable.

We know that the main cost for one hour is $5, and that each additional hour will cost $5.

Therefore, the equation to reflect this situation would be 5 + 5w, because the first 5 represents the first hour, and the 5w represents how much each hour costs. If you rent two extra hours, then the cost would end up being 15, because the equation would become: 5 + (5x2) = 15.

The equation is 5 + 5w. Hope this helps, and good luck!

See Explanation

Step-by-step explanation:

Your question do not have enough details for it to be answered. I will solve your question on a general terms using the attached image of a trapezoid

Given

[tex]Area = 8580ft^2[/tex]

From the attachment, we have:

[tex]BC = 100ft[/tex]

[tex]AD = 80ft[/tex]

[tex]h = 60ft[/tex] --- height

The perimeter (P) of a trapezoid is:

[tex]P = AB + BC + CD + AD[/tex]

Substitute values for AD, BC

[tex]P = AB + 100 + CD + 80[/tex]

Collect Like Terms

[tex]P = AB + CD + 80+ 100[/tex]

[tex]P = AB + CD + 180[/tex]

Next, is to calculate the lengths of AB and CD or the sum: AB + CD

The area of a trapezoid is:

[tex]Area = \frac{1}{2}(AB + CD) * h[/tex]

Substitute values for Area and h

[tex]8580= \frac{1}{2}(AB + CD) * 60[/tex]

Multiply both sides by 2

[tex]2*8580= \frac{1}{2}(AB + CD) * 60*2[/tex]

[tex]17160= (AB + CD) * 60[/tex]

Divide both sides by 60

[tex]\frac{17160}{60}= \frac{(AB + CD) * 60}{60}[/tex]

[tex]286 = AB + CD[/tex]

[tex]AB + CD=286[/tex]

Substitute 286 for AB + CD in: [tex]P = AB + CD + 180[/tex]

[tex]P = 286 + 180[/tex]

[tex]P = 466[/tex]

The perimeter of the backyard is 466ft.

The above steps should give you a hint on how to solve your actual question.

Answer:

y = 110

Step-by-step explanation:

ABCD is a cyclic quadrilateral ( its vertices are on the circle )

The opposite angles are supplementary, sum to 180° , then

∠ C = 180° - 70° = 110° , thus

y = 110

Because the formula of quadratic equations is y = ax² + bx + c where you can see the only equation with the power of two is equation B

Equation B into quadratic equation

5x² + x = y - 4

y = 5x² + x +4

Function 5x² + x = y - 4 is quadratic .

Hence option B is correct .

Given , Linear and Quadratic function.

Standard form of quadratic function : y = ax² + bx +c

a = coefficient of x² .

b = coefficient of x .

c = constant .

Rearranging the function,

5x² + x = y - 4

y = 5x² + x - 4

Comparing the equation with standard form,

a = 5

b = 1

c = -4

Hence option B is correct .

Answer: Step 3 was Gabi's mistake

The solution of the Gabi's equation is m = 28. the Gabi's mistake was division in step 3.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Step 1:  Distribute

0.1(0.5m + 6) = 2

(0.1 * 0.5m) + (0.1 * 6) = 2

0.05m + 0.6 = 2

Step 2:  Subtract 0.6 from both sides

0.05m + 0.6 - 0.6 = 2 - 0.6

0.05m = 1.4

Step 3:  Divide both sides by 0.05

0.05m / 0.05

= 1.4 / 0.05

m = 28

Hence, the solution of the Gabi's equation is m = 28. the Gabi's mistake was division in step 3.

Answer:

Step-by-step explanation:

Answer:

When we have a point (x, y) and we have a dilation of scale factor K about the origin, the new coordinates of the point will be:

(k*x, k*y)

In this case we have a dilation about point P, but let's assume that point P is the origin of coordinates.

Then the coordinates of point B will be (8, 12)

Then after the dilation of scale factor of 1/4, the new coordinates will be:

( (1/4)*8,  (1/4)*12) = (8/4, 12/4) = (2, 3)

This means that the dilated point will be 2 units at the right of P, and 3 units above P.

https://i.pinimg.com/originals/50/3f/9a/503f9a49a2faa03f7db90f090eea6bff.gif

Step-by-step explanation:

Answer:

Given:

A car travels 2 1/3 miles in 3 1/2 minutes.

We need to find the distance travelled in ​25 minutes, in 1 hour.

So, 2 1/3= 7/3 and 3 1/2 = 7/2

Let's convert them into decimals by dividing them completely.

So, we will get 2.33 miles and 3.5 minutes.

So now we have that 2.33 miles are covered in 3.5 minutes.

Now we need to know the distance covered in 1 minute.

So, 2.33/3.5=0.67

So now we have in one minute 0.67 miles are covered.

Now distance covered in 25 minutes will be:

0.67*25 = 16.75 miles

Now distance covered in one hour:

1 hour = 60 minutes.

So, 0.67*60 = 40.2 miles

So we have distance covered in 25 minutes-16.5 miles and in 1 hour- 40.2 miles.

Answer:

A = 192 in²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

Here h = 12, b₁ = AB = 14 and b₂ = DC = 2 + 14 + 2 = 18, then

A = [tex]\frac{1}{2}[/tex] × 12 × (14 + 18) = 6 × 32 = 192 in²
