Answers

Answer 1

Answer:

144m

Step-by-step explanation:

we would used tan 30 to determine the height of the building

tan 30 = opposite / adjacent

Point R is located at (1, 2) on a coordinate grid. Point S is located at (4, 5) on the same

A. 3.2 units

B. 4.6 units

C. 7.6 units

D.

10.0 units

Answers

Answer:

4.2 units

most likely answer choice B

Step-by-step explanation:

(1, 2) and (4, 5)

To find the distance between two points, we use the distance formula:

[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]

Let's plug in what we know.

[tex]d = \sqrt{(4 - 1)^2 + (5 - 2)^2 }[/tex]

Evaluate the parentheses.

[tex]d = \sqrt{(3)^2 + (3)^2 }[/tex]

Evaluate the exponents.

[tex]d = \sqrt{(9) + (9) }[/tex]

Add.

[tex]d=\sqrt{18}[/tex]

Evaluate the radical.

d = 4.24

Round to the nearest tenth.

d = 4.2 units

*note: The answer choice is 4.6. I'm not sure if that is a typo on someone's end, but the distance between these two points is exactly 4.24264068712 units.

Answers

Answer:

Step-by-step explanation:

We first need to figure out how much money Jackie has since Pilar has the same amount of money, but in different coins. Jackie has 24 dimes and 13 quarters, so the amount of money is $2.40 + $3.25 = $5.65; therefore, Pilar has $5.65 also. In order to determine how many nickels and quarters Pilar has, we have to have a system of equations. It's up to us to write the equations we need to solve this. The first equation has to do with the NUMBER of coins Pilar has, the second has to do with the VALUE of each coin. We know that Pilar has only nickels and quarters and that she has a total of 53 coins. So the NUMBER equation is

n + q = 53

The VALUE equation relates how much each coin is worth to the total amount of money it equals:

.05n + .25q = 5.65.

Go back to the first equation and solve it for either n or q. I solved it for n:

n = 53 - q

Plug this into the second equation in place of n now to get:

.05(53 - q) + .25q = 5.65 and

2.65- .05q + .25q = 5.65 and

.20q = 3 so

q = 15. This means that there are 15 quarters. If there are 15 quarters, then there are

n + 15 = 53 nickels and

n = 38 nickels.

A total of 42 gallons of a glycol solution needs to be added to a heating water loop to ensure the water does not freeze if there is a heating equipment failure. The glycol solution comes in​ 1.75-gallon cans. How many cans will be​ needed? Your answer should be a whole number.

Answers

Answer:

Number of cans of glycol solution needed = 24 cans

Step-by-step explanation:

Total glycol solution needed = 42 gallons

Volume of each can of glycol solution = 1.75 gallon

How many cans will be​ needed

Number of cans of glycol solution needed = Total glycol solution needed / Volume of each can of glycol solution

= 42 / 1.75

= 24

Number of cans of glycol solution needed = 24 cans

Answers

Answer:

2.) 145°

4.) 50°

Step-by-step explanation:

2.) First find the measure of Angle Y, since they are supplementary;

∠Z + ∠Y = 180

35 + ∠Y = 180

∠Y = 180 - 35

∠Y = 145°

So ∠X would be 145° as well

4.) First find the measure of Angle F, since they are supplementary;

∠C + ∠F = 180

130 + ∠F  = 180

∠F = 180 -130

∠F = 50°

So ∠E would be 50°

What is the measure of angleR to the nearest degree? TR-35 ST-30 S-69° •31° •53° •58° •80°​

Answers

In the diagram, the measure of angle R is 53°

Law of sines

From the question, we are to determine the measure of angle R

Using the law of sines, we can write that

[tex]\frac{sin R}{r} =\frac{sin S}{s}[/tex]

In the given diagram,

r = 30

S = 69°

s = 35

Thus,

[tex]\frac{sin R}{30} =\frac{sin 69^\circ}{35}[/tex]

[tex]sin R =\frac{30 \times sin 69^\circ}{35}[/tex]

sin R = 0.8002

R = sin⁻¹(0.8002)

R = 53.149°

R ≈ 53°

Hence, the measure of angle R is 53°

what is the sum of the exterior angle of a pentagon?​

Answers

Answer:

360°

Step-by-step explanation:

The exteriors angles of a pentagon are (m + 5)°, (2m + 3)°, (3m + 2)°, (4m + 1)° and (5m + 4)° respectively. Find the measure of each angle. Hints: The sum of all exterior angles of a polygon is 360°.

Step-by-step explanation:

The pentagon is not a regular one. If it were, all the angles would be 72, In addition you have to assume that when m has been solved that the m is constant for all angles.

m + 5 + 2m + 3 +3m+2 + 4m + 1 + 5m+ 4 =360

15m + 15 = 360 Subtract 15 from both sides

15m = 360 - 15 Combine

15m = 345 Divide by 15

m = 23

Answer

m + 5 = 28

2m + 3 =49

3m + 2 = 71

4m + 1 = 93

5m + 4 = 119
