SA = 2tr2 + 2trh (Use 3.14 for .) How much metal is needed to create a cylindrical can with a height of 5 inches and a base diameter of 3 inches? square inches Do NOT round your answer.
Answer:
[tex]SA=61.26\ \text{inches}^2[/tex]
Step-by-step explanation:
The surface area of a cylinder is given by :
[tex]SA=2\pi r^2+2\pi rh[/tex]
Where
r is radius and h is height of the cylinder
We have, h = 5 inches and r = 3/2 = 1.5 inches
Put all the respected values.
[tex]SA=2\pi \times (1.5)^2+2\pi \times 1.5\times 5\\\\SA=61.26\ \text{inches}^2[/tex]
So, the surface area of the cylinder is equal to [tex]61.26\ \text{inches}^2[/tex].

Question 10
The graph of a function includes the points (4, 5) and (21, 39).
What is the rate of change of the function?
A
2
B
34
с
17
D
0.5
Answer:
Step-by-step explanation:
The rate of change, slope, m is
m=(y2-y1)/(x2-x1), we have points (4,5) and (21,39) so
m=(39-5)/(21-4)
m=34/17
m=2
So the rate of change is 2
What is 9/10 as hundredths in fraction form and decimal form?

Internet company Gurgle is carrying out testing on the efficiency of its search engine. A sample of 31 searches have been carried out and the time taken to display the results has been recorded for each search. The mean search time for the sample was calculated as 0.2258 seconds. The standard deviation of the search times for the sample was calculated as 0.0188 seconds. The population standard deviation of search times is unknown.
1. Select all the techniques that are commonly used to construct a confidence interval for the mean when the population standard deviation (σ) is unknown:
a. Approximate the population standard deviation (σ) with the sample standard deviation (s)
b. Replace the sample size (n) with n-1
c. Decrease the confidence level to compensate for the increased margin of error
d. Approximate the standard normal distribution with the Student's t distribution
2. Calculate the upper and lower bounds of the 95% confidence interval for the mean search time for the Gurgle search engine.
Answer:
d. Approximate the standard normal distribution with the Student's t distribution
(0.2199 ; 0.2327)
Step-by-step explanation:
Given that :
Sample size, n = 31
Sample mean, xbar = 0.2258
Sample standard deviation, s = 0.0188
Confidence interval (C. I) :
xbar ± margin of error
Margin of Error : Tcritical * s/sqrt(n)
Degree of freedom, df = n - 1 = 31 - 1 = 30
Tcritical value :
T0.05/2, 30 = 2.042
Margin of Error = 2.042 * 0.0188/sqrt(31)
Margin of Error = 0.0068949
C. I = 0.2258 ± 0.0068949
Lower boundary : (0.2258 - 0.006895) = 0.2189
Upper boundary : (0.2258 - 0.006895) = 0.2327
(0.2199 ; 0.2327)

Answer:
The 20-count batteries have a lower unit price of $0.76 per battery
Step-by-step explanation:
Unit price means how much does it cost if you buy one of the item. To calculate this take the amount of money it cost and divide by the amount of object you have.
In the case of this question we know that you can buy 8 batteries for $6.16 and 20 batteries for $15.20. Let's find the unit cost (how much for one battery) for each of these packs. To calculate that we can take $6.16/8 batteries = $0.77 per battery for the 8 pack and $15.20/20 = $0.76 per battery for the 20 pack. Therefore, the 20-count batteries have a lower unit price of $0.76 per battery.

What does X and Y equal?
Answer:
X= 67
Y= 6
Step-by-step explanation:
Triangle TRU is an equilateral triangle which means all sides are equal.
Triangles sum up to 180°.
180/3= 60
60+7= 67
x=67
Triangle TRS is an isosceles triangle which means it has two equal sides.
Triangles sum up to 180°.
180-60= 120
TRS= 120°
60/2= 30°
RTS= 30°
RST= 30°
30/5= 6
y= 6

A total of P60,000 was invested, a portion at 5% and the remainder at 4.5%. The total amount of interest earned was P2,900. How much was invested at each rate?
Answer:
P40000 at 5%
P20000 at 4.5%
I am curious as to what the P stands for. Can you tell me?
Step-by-step explanation:
Let x = amt. invested at 5%
y = amt. invested at 4.5%
(1) x + y = 60000 (2) .05x + .045y = 2900
50x + 45y = 2900000
-45 times (1) -45x - 45y = -2700000
5x = 200000
x = 40000
40000 + y = 60000
y = 20000
P40000 at 5%
P20000 at 4.5%

Answer:
384 cm²
Step-by-step explanation:
The shape of the figure given in the question above is simply a combined shape of parallelogram and rectangle.
To obtain the area of the figure, we shall determine the area of the parallelogram and rectangle. This can be obtained as follow:
For parallelogram:
Height (H) = 7.5 cm
Base (B) = 24 cm
Area of parallelogram (A₁) =?
A₁ = B × H
A₁ = 24 × 7.5
A₁ = 180 cm²
For rectangle:
Length (L) = 24 cm
Width (W) = 8.5 cm
Area of rectangle (A₂) =?
A₂ = L × W
A₂ = 24 × 8.5
A₂ = 204 cm²
Finally, we shall determine the area of the shape.
Area of parallelogram (A₁) = 180 cm²
Area of rectangle (A₂) = 204 cm²
Area of figure (A)
A = A₁ + A₂
A = 180 + 204
A = 384 cm²
Therefore, the area of the figure is 384 cm²

What do all rhombuses have in common
Every rhombus has two diagonals connecting pairs of opposite vertices, and two pairs of parallel sides.
All rhombuses have equal sides and diagonals that bisect each other at right angles.
We have,
All rhombuses have the following characteristics in common:
- Equal Sides:
A rhombus is a quadrilateral with all four sides of equal length.
Each side of a rhombus has the same measurement.
- Opposite Angles are Equal:
The opposite angles of a rhombus are congruent (equal in measure). This means that if we label the angles A, B, C, and D in a clockwise or counterclockwise direction, then angle A is congruent to angle C, and angle B is congruent to angle D.
- Diagonals Bisect Each Other:
The diagonals of a rhombus are perpendicular bisectors of each other. This means that the diagonals intersect at a right angle, and they divide each other into two equal halves.
- Diagonals are Equal in Length:
The two diagonals of a rhombus are of equal length. If we label the endpoints of the diagonals as E, F, G, and H, then EF = GH.
Thus,
All rhombuses have equal sides and diagonals that bisect each other at right angles.
