Answer:
Hi there!
We've given with the base area and height. We know the formula for base area
Base area = πr²
154 = 22/7 × r²
154 × 7/22 = r²
49 = r²
√49 = r
7 = r
Now
TSA = 2πr(h + r)
TSA = 2 × 22/7 × 7(7 + 20)
TSA = 44(27)
TSA = 1188 cm²
Find angle A and angle E
Answer:
m∠A = 50°
m∠E = 50°
Step-by-step explanation:
7x - 17 and 2x + 8 are same side exterior angles. They have a sum of 180°.
7x - 17 + 2x + 8 = 180
9x - 9 = 180
9x = 189
x = 21
∠A and 7x - 17 are supplementary. ∠E and 2x + 8 are vertical angles.
m∠A + 7x - 17 = 180
m∠A + 7(21) - 17 = 180
m∠A + 147 - 17 = 180
m∠A + 130 = 180
m∠A = 50
m∠E = 2x + 8
m∠E = 2(21) + 8
m∠E = 42 + 8
m∠E = 50

Natasha's rectangle measures 4 1/2 units by 2 1/4 units. What is its area?
Answer:
Answer: 49/6units^{2}49/6units
2
Step-by-step explanation:
You can convert from mixed number to fractions as following:
2 1/3=((2*3)+1)/3=7/3 units
3 1/2=((3*2)+1)/2=7/2 units
Then you can calculate the area of the rectangle as you can see below:
\begin{gathered}Area=lenght*width\\Area=7/2units*7/3units\\Area=49/6units^{2}\end{gathered}
Area=lenght∗width
Area=7/2units∗7/3units
Area=49/6units

3(s-5)/4 -3 = 4s- (s-3)/2
answer fast meenu sister
Answer:
18
Step-by-step explanation:
3(s-5)/4 -3 = 4s- (s-3)/2
open the bracket
3s-15/4-3 =45-s-3/2
3s-15/1=42-s/2
cross multiply
2(3s-15)=42-s
3s-30=42-s
3s+s=42+30
4s=72
s=18
Answer:
s = -45/13
Step-by-step explanation:
3(s - 5)/4 - 3 = 4s - (s - 3)/2
(3s - 15)/4 - 3 = (8s - s + 3)/2
(3s - 15)/4 - 3 = (8s + 3)/2
3(s - 5)/4 - 3 = 3((8/3)s + 1)/2
3[(s - 5)/4 - 1 ] = 3((8/3)s + 1)/2
(s - 5)/4 - 1 = ((8/3)s + 1)/2
(s - 5)/4 - 4/4 = ((8/3)s + 1)/2
(s - 5 - 4)/4 = ((8/3)s + 1)/2
(s - 9)/4 =((8/3)s + 1)/2
(s - 9) = ((8/3)s + 1)(2)
s - 9 = (16/3)s + 2
s - (16/3)s = 6 + 9
(-13/3)s = 15
s = -45/13

Write a function to describe the following scenario.
Raw cake batter starts at a thickness of
2 centimeters in a pan but grows at
0.15 centimeters every minute in the oven.
How tall will the cake be after
a certain number of minutes?
Answer:
y = 0.15x + 2
Step-by-step explanation:
Let's say x represents the number of minutes and y represents the thickness of the cake.
No matter what, the cake will start at a thickness of 2 centimeters. Whatever thickness is added on/subtracted starts at 2 centimeters, so y = 2 + or - something.
Next, the batter grows by 0.15 centimeters every minute. This means that every minute, 0.15 centimeters are added to the thickness of the cake. This can be represented by
0.15 * x
Adding these two together, we get
y = 2 + 0.15 * x
y = 0.15 * x + 2
