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’s the value of x
Answer:
C. x=42
Step-by-step explanation:
16 + 3x + y = 180
126 + 16 + y = 180
y = 38
16 + 3x + 38 = 180
54 + 3x = 180
3x = 126
x=42

Answer:
"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, wher all you have to do is simplify; that is more of an order-of-operations kind of question. In this lesson, I'll concentrate on the "plug and chug" aspect of evaluation: plugging in values for variables, and "chugging" my way to the simplified answer.

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
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:
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.
-hx + 4 = 2x- 1 solve this equation for x.
Answer:
x=-5/(-h-2)
Step-by-step explanation:
-hx+4=2x-1

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)

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:

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.
