Manuel incorrectly claimed that the surface area of the cylinder
shown is about 621.7 in.. Use a formula to find the surface area of the cylinder.
Use 3.14 for it. What was his likely error?
11 in
The surface area of the cylinder is about
(Round to the nearest tenth as needed.)
Answer:
25.9%
Step-by-step explanation:
Since, the actual dimensions of the cylinder is not given we can assume the some dimension to explain the problem
Let us assume the dimension of the cylinder be
radius= 3in
height= 5 in
The expression for the total surface area of a cylinder is
T. S. A. =2πrh+2πr^2
Let us plug in the values to to find TSA
T. S. A. =2×3.14×3×5+2×3.14×3^2
Solving we get
T. S. A. =94.26+56.556
T. S. A. =150.816 in^2
Now let us find the error
we know that error % is calculated as
%error= [actual value-expected value/expected value]×100
%error= [190 -150.816/150.816]×100
%error= [39.184/150.816]×100
%error= 0.259×100
%error= 25.9%

Miguel bought a ¾ pound bag of chocolate chips. He used ⅘ of the bag in his chocolate chip cookies. How many pounds of chocolate chips did he use?
Convert to percentages to understand the question better:
3/4 = 75%
4/5 = 80%
What is 80% of 75%?
Convert the percentages to decimals:
75% = 0.75
80% = 0.8
Calculate:
0.8 × 0.75 = 0.6
Convert back to original problem's format (fraction):
0.6 = 60% = 6/10 = 3/5
Miguel used 3/5 pounds of chocolate chips.

10 in
Answer: 800
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
The surface area of the figure is 40 + 5π.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.

We have,
From the figure,
We have a semicircle and a rectangle.
Now,
Diamter = 10 in
Radius = 5 in
Circumference = 2πr
Semicircle circumference = πr
Now,
The surface area of the figure.
= 15 + 10 + 15 + πr
= 40 + 5π
Thus,
The surface area of the figure is 40 + 5π.

Explanation:
The line passing through (-3 , -6) and (d, -5d) has a gradient of -3.
Find the value of d.
Answer:
d = 7.5
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to - 3
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, - 6) and (x₂, y₂ ) = (d, - 5d)
m = [tex]\frac{-5d+6}{d+3}[/tex] = - 3 ( multiply both sides by (d + 3) )
- 5d + 6 = - 3(d + 3)
- 5d + 6 = - 3d - 9 ( add 3d to both sides )
- 2d + 6 = - 9 ( subtract 6 from both sides )
- 2d = - 15 ( divide both sides by - 2 )
d = 7.5
Find the midpoint of the line on the coordinate plane with the given endpoints below.
(-1, 1), (5, -5)
Answer:
Then the midpoint is (2, -2)
Step-by-step explanation:
We treat the x- and y-coordinates separately, first finding the average (mean) of the x-coordinates and then the average of the y-coordinates:
xm = (-1 + 5)/2 = 2
ym = (1 - 5)/2 = -2
Then the midpoint is (2, -2)
Answer:
(2,-2)
Step-by-step explanation:
Two points are given to us and we need to find the midpoint of those two points. The points are
(-1,1) and (5,-5) . Let us say we have two points ( x1,y1) and ( x2 , y2) . The midpoint will be ,
[tex]\implies Midpoint =\bigg( \dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2} \bigg) \\\\\implies Midpoint = \bigg( \dfrac{-1+5}{2},\dfrac{1-5}{2}\bigg)\\\\\implies Midpoint = \bigg( \dfrac{4}{2},\dfrac{-4}{2}\bigg)\\\\\implies \red{Midpoint = ( 2 , -2) }[/tex]

Clara has 9 pounds of apples. She needs 1 1/4 pounds to make one apple pie. If she saves 2 pounds for applesauce, how many pies, p, can she make? Write an algebraic equation to represent this situation.
Answer:
She can make :
5 3/5 pies
Algebraic equation =
1 1/4 p = (9 - 2)
Step-by-step explanation:
Clara has 9 pounds of apples. If she saves 2 pounds for applesauce, how many pies, p, can she make?
Total number of pounds of apples = 9 pounds
She saves 2 pounds for apple sauce
The number of pounds of apples left =
9 pounds - 2 pounds
= 7 pounds
She needs 1 1/4 pounds to make one apple pie.
Therefore
1 1/4 pounds = 1 apple pie
7 pounds = p
Cross Multiply
1 1/4 × p = 7 × 1
p = 7 ÷ 1 1/4
p = 7 ÷ 5/4
p = 7 × 4/5
p = 28/5
p = 5 3/5 pies
An Algebraic equation for this situation is:
1 1/4 p = (9 - 2)
Where p = Number of pies
A movie theater sells popcorn in bags of different sizes. The table shows the volume of popcorn and the price of the bag. If the theater wanted to offer a 60-ounce bag of popcorn, what would be a good price? Explain your reasoning
Answer:
For a volume of 60 ounces, the appropriate price is $16
Step-by-step explanation:
Firstly, we need to determine the relationship between volume of popcorn and the price of bag.
Let us try and see if there is a linear relationship
A linear model is of the form ;
y = mx + b
where m is the slope and b is the y intercept
While the price represents the y axis values, the volume represents the x axis values
For the slope;
m = (y2-y1)/(x2-x1)
m = (13.6-11)/(48-35) = 2.6/13 = 0.2
So we have the slope value as 0.2
the equation is;
y = 0.2x + b
to get b, substitute any value of (x,y)
6 = 0.2(10) + b
6 = 2 + b
b = 6-2 = 4
If we had substituted (20,8)
8 = 0.2(20) + b
8 = 4 + b
b = 4
if (48,13.6)
13.6 = 48(0.2) + b
13.6 = 9.6 + b
b = 13.6-9.6
b = 4
Hence we have established linear relationship between the volume in ounces and the price in $
So we have this as
Price = 0.2(volume) + 4
So for volume of 60 ounces;
Price = 0.2(60) + 4
price = 12 + 4
price = $16
The reason why this is appropriate is because it follows the rule of the established linear relationship
Answer:
$16

g(x)=3x+2 and h(x)=ax+B
where a and b are constants
h(4)=22
g^-1(14)=h(1)
find the value of a and the value of b
Answer:
a=6
b=-2
Step-by-step explanation:
You can use the hint provided on the mathswatch question page, I've attached it below
step 1
h(4) = ax+b = (ax4)+b = 4a+b
it is given in the question that h(4)=22, therefore 4a+b=22
step 2
work out the equation for inverse g
g^-1(x) = [tex]\frac{x-2}{3}[/tex]
step 3
input 14 into the equation in place of x to find g^-1(x)
[tex]\frac{x-2}{3} =\frac{14-2}{3} =\frac{12}{3} =4[/tex]
so, g(x)^-1=4
step 4
find h(1):
h(1) = (ax1)+b = a+b
so, h(1)=a+b
step 5
a+b=4 (as it is given in the question that g^-1(14) is equal to h(1))
step 6
Now you have two simultaneous equations:
4a+b=22
a+b=4
then, solve for a:
4a+b=22
- a+b=4
3a=18
a=6
then, input answer for a into either equation (I've gone with the a+b=4 equation):
6+b=4
-6 - 6
b=-2
