Answer:
Volume of a cone = 50 in³
Step-by-step explanation:
diameter = 5 in
radius = 2.5 in
height = 8 in
Volume of cone = [tex]\frac{\pi r^2h}{3}[/tex]
V = (3 × 2.5 × 2.5 × 8)/3
V = 150/3
V = 50 in³
a straight line passing through A(3,2) and B(5,y) has gradient -2. find the value of y
Step-by-step explanation:
[tex]gradient \: = \: \frac{y2 - y1}{x2 - x1} [/tex]
y2 = y , x2 = 5
y1 = 2 , x1 = 3
[tex] - 2 \: = \: \frac{y - 2}{5 - 3} [/tex]
-4 = y-2 ==> y = -2
Answer:
y=-2
Step-by-step explanation:
For a line containing the points (X1,Y1) and (X2,Y2), the gradient/slope is equal to (Y2-Y1)/(X2-X1).
Therefore for a line with gradient -2 and points (3,2) and (5,y), we can say:
-2=(y-2)/(5-3)
-2(2)=y-2
y=-4+2
y=-2

The Great Park Balloon in Orange County, California, is a big orange sphere with a radius of 36 feet. Find its surface area (in square feet). (Use 3.14 for . Round your answer to one decimal place.)
Answer:
16286
Step-by-step explanation:
the formula for surface area for a sphere is 4 pi r^2
So substitute for r and you get 4pi*1296 then do 3.14 * 4 * 1296 and you get 16286.02 then round it to one decimal (it cancels out) and you get 16286.

The length of a rectangle is 3 yd more than twice the width, and the area of the rectangle is 54 yd?. Find the dimensions of the rectangle.
Answer:
The length of the rectangle is 37 yards, and the width of the rectangle is 17 yards.
Step-by-step explanation:
Given that the length of a rectangle is 3 yards more than twice the width, and the area of the rectangle is 54 yards, the following calculation must be performed to find the dimensions of the rectangle, knowing that the area of a rectangle arises from multiplying its base by its height:
2X + 3 + X = 54
3X + 3 = 54
3X = 54 - 3
X = 51/3
X = 17
(17 x 2) + 3 = 37
Therefore, the length of the rectangle is 37 yards, and the width of the rectangle is 17 yards.

At a snack bar, each medium drink costs $1.85 and each large drink cost c more dollars than a medium drink. If 5 medium drinks and 5 large drinks cost a total of $20.50, what is the value of c?
A) 0.45
B) 0.40
C) 0.30
D) 0.25
Answer:
B) 0.40
Step-by-step explanation:
m = 1.85
l = 1.85 + c
With 5 medium drinks and 5 large drinks:
C = 5m + 5l
20.5 = 5(1.85) + 5(1.85 + c)
20.5 = 9.25 + 9.25 + 5c
20.5 = 18.5 + 5c
5c = 20.5 - 18.5
5c = 2
c = 2/5 = 0.4

Dmitri will need
18 cm
glass tiles.
9514 1404 393
Answer:
968
Step-by-step explanation:
The area of the top and sides is given by the formula ...
A = LW +2H(L +W)
A = (20 cm)(18 cm) +2(8 cm)(20 cm +18 cm)
A = (360 +16(38)) cm² = 968 cm²
Since the tiles are 1 cm², 968 tiles are needed.

Answer:
150 kg
Step-by-step explanation:
here is the complete question
A rectangular gate is made using 6 straight pieces of steel.
5 m
12 m
The weight of the steel is 2.5 kg per metre.
Work out the total weight of the steel gate.
To solve this question determine the square root of 12 and 5
√169 = 13
5 + 12+ 5 + 12+ 13 + 13 = 60 m
total weight = 60 x 2.5 = 150kg

Answer:
PQ=36
Step-by-step explanation:
If the triangles are similar, then they must have a common ratio between them.
RQ corresponds with CB, so [tex]\frac{84}{18}=\frac{14}{3}[/tex]
If the ratio is [tex]\frac{14}{3}[/tex], then [tex]\frac{168}{\frac{14}{3}}=36[/tex], so PQ=36.
Here are summary statistics for randomly selected weights of newborn girls: n=250, x_=32.9 hg, s= 6.9 hg. Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 31.9 hg < μ < 34.5 hg with only 19 sample values, x_=33.2 hg, and s=2.6hg? What is the confidence interval for the population mean μ?
Answer:
a) ( 31.92 < μ < 33.88 )
The confidence interval is not very different from the confidence interval given in the question
b) ( 31.74 , 34.66 )
Step-by-step explanation:
n = 250
x ( mean ) = 32.9
std = 6.9
95% confidence interval
df = n - 1 = 250 - 1 = 249
a) construct confidence interval estimate
calculate for the margin of error
= [tex]t_{0.05/2} ,_{250-1} ( \frac{s}{\sqrt{n} } )[/tex] ( using excel function: T.INV.2T(0.025,249) )
= 2.255 ( 6.9 / 15.81 )
= 0.98
Hence the confidence interval for the population
= ( x - 0.98 < μ < x + 0.98 )
= ( 31.92 < μ < 33.88 )
The confidence interval is not very different from the confidence interval given in the question
b) when n = 19
x = 33.2 and std = 2.6
margin of error = [tex]t_{0.05/2} ,_{19-1} ( \frac{s}{\sqrt{n} } )[/tex] = 2.45 * ( 2.6 / 4.36 ) = 1.46
confidence interval
= ( 33.2 - 1.46 , 33.2 + 1.46 )
= ( 31.74 , 34.66 )

Of the following fractions: 9/19, 5/11, 7/15, and 11/23, which is the largest?
Answer: 11/23
Step-by-step explanation:
I used my calculator to convert those fractions into decimal form and found the biggest number. It was about 0.4789.
The largest fraction will be 11/23.
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
Given that;
All the fractions are,
⇒ 9/19, 5/11, 7/15, and 11/23
Now,
Since, All the fractions are,
⇒ 9/19, 5/11, 7/15, and 11/23
Here, The values are,
⇒ 9 /19 = 0.47
⇒ 5/11 = 0.45
⇒ 7/15 = 0.46
⇒ 11/23 = 0.48
Thus, The largest value of the fraction = 11/23
