Find the area of the circle from the given diameter.
d= 4 ft
a 11.4 ft2
b 12.56 ft2
C 10.81 ft2
d 14.98 ft2
Answer:
B is our answer 12.56
When finding area for circles we do
radius x radius x pi
Since we don't have the radius in the problem we have to figure it out but it wont be so hard knowing that the radius is half of the diameter so 4 ÷ 2 = 2 so 2 is our radius now we need tp square it in easier words multiply by itself so
2 x 2 = 4 then we just do 4 x pi!
So 4 x 3.14 = 12.56 So our answer is 12.56
Hope this helps!
Jayda was buying a new pair of sneakers from an
online store. The original price was $96. The store was
having 35% off all sneakers. A 9% processing fee will
be applied to the cost of the sneakers, plus a shipping
fee of $4.99. How much will she pay for the sneakers,
including discounts, fees and shipping?
A) $73.01
C) $68.02
B) $58.75
D) $63.03
Answer:
A/$73.01
Step-by-step explanation:
Step One (1) : 35% off of $96 is %63.03. (This removes option D)
Step Two (1) : $63.03+The Shipping Fee ($4.99)
Step Three (3) : Add the 9% Processing Fee
Step Four (4): The Answer is $73.01!
I hope this helps and I hope you have a great day!

Please helppppppppppppppppp
Answer:
Step-by-step explanation:
1)
a/c =b/d where a=27 c=30 b=x d=18
27/30 = x/18
27*18/30=x
16.2 = x
2)
a/c =b/d where a=2x-5 c=x+11 b=16 d=14
2x-5 / x + 11 = 16 / 14
14(2x-5) = 16(x+11)
28x - 70 = 16x + 176
12x = 246
x = 20.5
3)
6+15 / 7+x = 7 /6
6(6+15) = 7(7+x)
6*21 = 49 +7x
126 = 49 +7x
77 = 7x
11 = x
4)
3*[(x-6)+3]=[tex]6^{2}[/tex]
3(x-3) = 36
3x-9 = 36
3x = 45
x = 15

Mel is 7cm less then her grandma's height. Her brother is 11cm taller then his grandma. Together height total 502 cm. What are their heights?
Answer:
Mel's height is 159cm, her brother's height is 177cm and their grandma's height is 166cm.
Step-by-step explanation:
Let the grandma's height be g cm.
Mel's height= (g -7) cm
Brother's height= (g +11) cm
Total height
= Mel's height +brother's height +grandma's height
= g -7 +g +11 +g
= (3g +4) cm
Given that their total heights is 502 cm,
(3g +4) cm= 502 cm
3g +4= 502
3g= 502 -4 (-4 on both sides)
3g= 498
g= 166 (÷3 on both sides)
To find their heights, substitute g= 166 back into the expressions.
Grandma's height= 166cm
Mel's height
= 166 -7
= 159cm
Brother's height
= 166 +11
= 177cm

Answer:
The correct option is (b).
Step-by-step explanation:
Given that,
The radius of the circle, r = 8 cm
The area of the sector, [tex]A=56\pi \ cm^2[/tex]
We need to find the measure of the sentral angle. The formula for the area of a sector is given by :
[tex]A=\dfrac{1}{2} r^2\theta[/tex]
Where
[tex]\theta[/tex] is the central angle
Substitute all the values,
[tex]\theta=\dfrac{2A}{r^2}\\\\\theta=\dfrac{2\times 56\pi }{8^2}\\\\\theta=\dfrac{7\pi}{4}\ rad[/tex]
So, the correct option is (b).

Rose uses 8.3 pints of white paint and blue paint to paint her bedroom walls. 3 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer: Rose used 2.075 pints of blue paint for her bedroom walls
Step-by-step explanation:
Amount of white and blue paint used for bedroom walls=8.3 pints
Amount of white paint used =3/4 x8.3 pints =6.225 pints
Amount of blue paint used = Amount of white and blue paint used for bedroom walls-Amount of white paint used
8.3 pints - 6.225 pints=2.075 pints

SOMEONE HELP ASAP WHATS THE MISSING ANGLE
Answer:
130
Step-by-step explanation:
? is an exterior angle of a triangle
An exterior angle is equal to the sum of the two opposite interior angles ( 35 and 95 in this case )
That being said the missing angle = 95 + 35
95 + 35 = 130
Hence, the answer is 130
Answer:
130
Step-by-step explanation:
1. We have a triangle and all angles in a triangle sum up to 180, so do 35+95 and then subtract the difference from 180, and you get 50
2. Now we have a linear pair next to 50' on the outside, signifying a linear pair, meaning that both angles should sum up to 180, so 180-50= 130

According to the US Census, the percent of residents aged 65 or older in the 50 states and District of Columbia has mean 13.26% and standard deviation of 1.67% Find and interpret the standardized score for the state of Colorado, which had 9.7% of residents age 65 or older.
Answer:
z = -2.13
The standardized score for the state of Colorado is negative and this means the score is smaller than the mean.
Step-by-step explanation:
The above question can be solved using z score.
The formula for z score is given as:
z = (x-μ)/σ,
where
x is the raw score = 9.7%
μ is the population mean = 13.26%
σ is the population standard deviation = 1.67%
z = z score or standardize score
Hence,
z = 9.7 - 13.26/1.67
z = -2.13174
Approximately z = -2.13
Therefore, the standardized z score for the state of Colorado is negative and this indicates that the score is below or smaller than the mean.

Answer:

Step-by-step explanation:
When the rocket is on the ground, then h = 0 , that is
- 6t² + 30t = 0 ← factor out - 6t from each term
- 6t(t - 5) = 0
Equate each factor to zero and solve for t
- 6t = 0 ⇒ t = 0 ← when rocket is launched
t - 5 = 0 ⇒ t = 5 ← time when rocket returns to ground
