Answer:
144m
Step-by-step explanation:
we would used tan 30 to determine the height of the building
tan 30 = opposite / adjacent
0.5774 x 250 = 144m
A parallelogram has a base length of 9.3 inches and an area of 56.73 squared inches. Find the height of the parallelogram.
Answer:
the answer is 6.1
Step-by-step explanation:
h= A over B (means you divide) and you get 6.1
Answer:
answer: the height is 6.1
Step-by-step explanation:
Because 56.73 ÷ 9.3 = 6.1 and for parellolograms base x height = area So doing area divided by base length will get us our height! Hope this helps!

Point S is located at (4, 5) on the same
coordinate grid. What is the distance from point R to point S, rounded to the nearest tenth?
A. 3.2 units
B. 4.6 units
C. 7.6 units
D.
10.0 units
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.

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.

Nine times the difference of a number and 4 is the same as the product of 2 and the same number plus 10. What is the number?
Answer:
The product of 10 and a number is = 10x Twice that number means 2x 36 less than twice that number= 2x-36. It is given that....The product of 10 and a number is the same as 36 less twice that same number
Step-by-step explanation:
The required number that is Nine times the difference of a number and 4 is the same as the product of 2 and the same number plus 10, is 8.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Let the number x,
According to the question,
9 (x - 4) = 2(x + 10)
Simplifying,
9x - 36 = 2x + 20
9x - 2x = 36 + 20
7x = 56
x = 56 / 7
x = 8
Thus, the required number that is Nine times the difference of a number and 4 is the same as the product of 2 and the same number plus 10, is 8.

earth's radius is approximately 4000 mi. about two thirds of the Earth's surface is covered by water. estimate the land area on earth
9514 1404 393
Answer:
67 million square miles
Step-by-step explanation:
The area of a sphere is given by ...
A = 4πr²
So the area of the Earth is approximately ...
A = 4π(4000 mi)² ≈ 2.01×10^8 mi²
The area of the 1/3 that is not covered by water is approximately ...
(2.01×10^2 mi²)/3 = 6.7×10^7 mi²
The land area is estimated to be about 67 million square miles.

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.
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

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°
In the diagram, the measure of angle R is 53°
Law of sinesFrom 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?
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
The total does come to 360
