In △ACD, if AC ≅ AD, m∠A = (3x – 4)°, m∠C = (5x + 1)°, and m∠D = (7x – 27)°, find x and the measure of each angle. *

Answers

Answer 1

Answer:

x = 14

A = 38

B = 71

C = 71

Step-by-step explanation:

Since we have a triangle, the addition of the measure of all the measure of the angles give 180

Thus;

3x-4 + 5x + 1 + 7x-27 = 180

15x-30 = 180

15x = 180 + 30

15x = 210

x = 210/15

x = 14

To get the measure of each of the angles, we substitute for x

A = 3x-4 = 3(14) - 4 = 38

B = 5x + 1 = 5(14) + 1 = 70 + 1 = 71

C = 7x - 27 = 7(14) - 27 = 98-27 = 71

The radius of a cylindrical water tank is 6.5 ft, and its height is 19 ft. What is the volume of the tank? Use the value 3.14 for pi, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer. (ft, ft^2, or ft^3)​

Answers

Answer: 2521.91 ft^3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Using the cylinder volume formula, V = (pi)r^2h

Since the radius and the height have already been given, no further calculations are necessary.

V= (pi)(6.5)^2(19)

V=(3.14)(42.25)(19)

We conclude that the estimated volume of a cylinder is 288 in.³

Step-by-step explanation:

Given

r = 3.75 inchesh = 6.21 inches

The formula to determine the volume of a cyliner is:

[tex]V=\pi r^2h[/tex]

substituting the values r = 3.75 inches, h = 6.21 inches, and π = 3.14 in the formula to calculate the volume of a cylinder.

[tex]V=\pi r^2h[/tex]

[tex]V=\left(3.14\right)\left(3.75\right)^2\times 6.21[/tex]

The sum of the areas of Square N and Square L is equal to the area of Square K and this can be determined by using the Pythagorean theorem.

Given :

The diagram shows three squares that are joined at vertices to form a right triangle.

The following steps can be used in order to determine which statement is true:

Step 1 - The Pythagorean theorem can be used in order to determine which statement is true.

Step 2 - According to the Pythagorean theorem, the sum of the square of the shorter sides is equal to the square of the longer side.

Step 3 - So, from the above steps, it can be concluded that the sum of the areas of Square N and Square L is equal to the area of Square K.

Therefore, the correct statement is given by option A).

Last week, Lindsay earned $10 per hour plus a $60 bonus for good job performance. She spends StartFraction 1 Over 15 EndFractionof her paycheck on dinner with friends. If she had not earned the bonus, the amount she spent on dinner would have been StartFraction 1 Over 10 EndFraction of her paycheck. Which equation can be used to find h, the number of hours Lindsay worked last week?

Answers

Answer:

Let

y--------> cost of the dinner with friends

h--------> the number of hours Lindsay worked last week

we know that

y =\frac{1}{15} *( 10h+60)y=

15

1

∗(10h+60) ------> equation 11

y =\frac{1}{10} *( 10h)y=

10

1

∗(10h) ------> equation 22

equate equation 11 and equation 22

\begin{gathered} \frac{1}{15} *( 10h+60)=\frac{1}{10} *( 10h)\\\\ Multiply\ by\ 150\ both\ sides\\\\ 10*(10h+60)=15*10h\\\\ 100h+600=150h\\\\150h-100h=600\\\\ h=\frac{600}{50} \end{gathered}

15

1

∗(10h+60)=

10

1

∗(10h)

Multiply by 150 both sides

10∗(10h+60)=15∗10h

100h+600=150h

150h−100h=600

h=

50

600

h= 12\ hoursh=12 hours

therefore

the answer is

Lindsay worked 12\ hours12 hours last week

The equation that can be used to find the number of hours is

\frac{1}{15} *( 10h+60)=\frac{1}{10} *( 10h)

15

∗(10h+60)=

10

∗(10h)

Lindsay worked for about 120 hours last week.

What is an equation?

An equation is used to show the relationship between two or more variables and numbers.

Let h represent the number of hours Lindsay worked last week, hence:

(1/15)(10h + 600) = (1/10)(10h)

40h + 2400 = 60h

h = 120 hours

Lindsay worked for about 120 hours last week.

Write an equation in point-slope form of the line that passes through the two given points. Use the first point to write the equation (-1, -5) and (3, 2)

Answers

Answer:

The equation in point-slope form of the line is:

[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]

Step-by-step explanation:

Given the points

(-1, -5) (3, 2)

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:-5\right),\:\left(x_2,\:y_2\right)=\left(3,\:2\right)[/tex]

[tex]m=\frac{2-\left(-5\right)}{3-\left(-1\right)}[/tex]

[tex]m=\frac{7}{4}[/tex]

As the point-slope form is defined as

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

where m is the slope.

substituting the values m=7/4 and the first point (-1, -5)

[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]

Therefore, the equation in point-slope form of the line is:

[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]
