Answer.
Step-by-step explanation:
Given = sum of two exterior angle of a triangle is 272 .
rule of triangle is that each and every angle which are outside a triangle is 360.
so, 272 + x = 360
x = 360 - 272
x = 88

AUB = {1, 2, 6, 8, 9, 11, 15, 20}the amount of gasoline used by a car varies jointly as the distance travelled and the square root of the speed.Suppose a car used 25 liters on a 100 km trip at 100kph,about how many liters will it use on 1000 km trip at 64 kph?
Answer:
200 litres
Step-by-step explanation:
let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is
g = kd[tex]\sqrt{s}[/tex] ← k is the constant of variation
To find k use g = 25, d = 100 and s = 100, then
25 = k × 100 × [tex]\sqrt{100}[/tex] = k × 100 × 10 = 1000k ( divide both sides by 1000 )
0.025 = k
g = 0.025d[tex]\sqrt{s}[/tex] ← equation of variation
When d = 1000 and s = 64, then
g = 0.025 × 1000 × [tex]\sqrt{64}[/tex] = 0.025 × 1000 × 8 = 200
Tiffany makes a round pizza. She wants to put a cheese layer on the pizza. If the pizza has a diameter of 18 cm, how many square cm of cheese layer does she need to put on the pizza?
Answer:
[tex]A=254.46\ cm^2[/tex]
Step-by-step explanation:
Given that,
The diameter of the pizza, d = 18 cm
We need to find the square cm of cheese layer does she need to put on the pizza.
We know that the area of the circle is given by :
[tex]A=\pi r^2[/tex]
Where
r is the radius of the circle
Here, r = 9 cm
So,
[tex]A=\pi (9)^2\\\\A=254.46\ cm^2[/tex]
So, the area of the pizza is [tex]254.46\ cm^2[/tex].

What percent of 59 is 44.1? Round the answer to the nearest
hundredth of a percent if necessary.
Answer:
133.78684807256
Step-by-step explanation:
step 1: We need the assumption that 44.1 is 100% since it is our output value
step 2: We need to represent the value we seek in x
step 3: From step 1, it follows that 100% = 44.1
step 4: In the same vein x% = 59
step 5: This give us a pair of simple equations:
100% = 44.1 (1)
x% = 59 (2)
step 6: by simplify dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have
[tex] \frac{100}{x} = \frac{44.1}{59} [/tex]
step 7: Taking the inverse (or reciprocal) of both sides yields
[tex] \frac{x}{100 } = \frac{59}{44.1} [/tex]
= x = 133.78684807256
Therefore, 59 is 133.78684807256% of 44.1

Which sentence uses correlative conjunctions?
A. On her way to the park, Letty found both a purse and a cell phone.
B. Fred wanted to play his video game, but he had to finish his homework first.
C. Angie added up her allowance and found that she had enough to buy the sports shoes.
D. In art class, we all had to draw the still life, or we would not be ready to paint it the next day.
Answer: It's A if not put B
Step-by-step explanation:
Since correlative conjunctions are used to connect parts of a sentence with equal value, we only need to use a comma when two independent clauses are being connected with correlative conjunctions.Correlative conjunctions include pairs such as “both/and,” “either/or,” “neither/nor,” “not/but” and “not only/but also.

The two triangles above are similar. If r = 19, v = 18, and u = 21, what is the value of s? Round answer to the nearest hundredth (2 decimal places).
Answer:
s=22.17
Step-by-step explanation:
v/r=u/s
18/19=21/s
18s=21(19)
18s=399
18s/18=399/18
s=22.17

Answer:
es 8 ksnfjskausksufbab 726+47272774
Answer:
(x. y) =(4, 7)
Step-by-step explanation:
-7 x - 2 y = 14
6 x + 6 y = 18
Solve the equation
x = - 2/7 y
6 x + 6 y = 18
Substitute the value of x
6 ( - 2 - 2/7y) + 6 y = 18
Solve the equation
y = 7
Substitute the value of y
x = - 2 - 2/7 x 7
Solve the equation
x = - 4
A possible solution is
(x, y) = (- 4, 7)
Check the solution
- 7 x ( - 4) - 2 x 7 = 14
6 x ( - 4) + 6 x 7 = 18
Simplify
14 = 14
18 = 18
The ordered pair is the solution
(x, y) = ( - 4, 7)

Find the volume of a pyramid with a square base, where the perimeter of the base is 18.5 ft and the height of the pyramid is 7.6 ft. Round your answer to the nearest tenth of a cubic foot.
Answer:
28.4in³
Step-by-step explanation:
Volume of the square based pyramid = L²H/3 where;
L is the length of a side of the square base
H is the height of the prism
Given
Perimeter of the base = 13.4 in
Height of the pyramid = 7.6in
First we need to get the length of the square base
Perimeter of a square = 4L
13.4 = 4L
L = 13.4/4
L = 3.35 in
Next is to find the required volume of the pyramid
V = L²H/3
V = 3.35²(7.6)/3
V = 85.291/3
V = 28.4 in³
Hence the volume of the pyramid to nearest tenth is 28.4in³
Answer: Answer:

What are the coordinates of the point in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6?
Answer:
The coordinates of the point P in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6 will be:
(x, y) = (-1, -7)Step-by-step explanation:
Let P be the point.
As the point P is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6
i.e.
(x₁, y₁) = (-2,-8)
(x₂, y₂) = (5,-1)
Rise = y₂ - y₁ = -1 - (-8) = -1 + 8 = 7
Run = x₂ - x₁ = 5 - (-2) = 5 + 2 = 7
1 : 6 ratio means the point P lies at
[tex]\frac{1}{6+1}=\frac{1}{7}=14\%[/tex]
Thus,
rise for P = 7 × 14% = 1
run for P = 7 × 14% = 1
Thus, coordinates of P will be:
x = -2 + 1 = -1
y = -8 + 1 = -7
Thus,
The coordinates of the point P in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the ratio of 1 to 6 will be:
(x, y) = (-1, -7)I need the answer please?
Answer:
84
Step-by-step explanation:
[tex]7 + (15 - 5) \times (10 - 6) \times \frac{1}{2} + 5 \times 10 = 84[/tex]
Answer:
The answer is 84 inches Squared!
Step-by-step explanation:
Here is the explanation to the answer:-
All you have to do is divide the whole figure into some parts!
Here is what I have divided the figure into.
The triangle area is 1/2 * L*H
The measurements are 1/2 * 4*3 = 6in Squared.
( The Next Shape To The Triangle)
Rectangle area is L*B
The Measurements are 4*7 = 28inches Squared.
(The next shape to the rectangle)
Rectangle area is L*B
Measurements are 5*4 = 20inches squared.
(Above Shape of the rectangle)
Area of rectangle is L*B
Measurements are 6*5 = 30 Inches Squared.
Now, add all the areas of the figure:-
6 + 28 + 20 + 30 = 84 Inches Squared.
Thanks, and hope this helps.
