Answer:
19.72 cm²
Step-by-step explanation:
A solid circular cylinder has a base radius 5 cm and a height 12.5 cm.
The volume of cylinder is given by :
[tex]V=\pi r^2 h\\\\=3.14\times (5)^2\times 12.5\\\\=981.25\ cm^2[/tex]
When r = 5.05, new volum becomes,
[tex]V=\pi r^2 h\\\\=3.14\times (5.05)^2\times 12.5\\\\=1000.97\ cm^2[/tex]
Increase in area = 1000.97 - 981.25 = 19.72 cm²
So, the increase in surface area of the cylinder is equal to 19.72 cm².

help me please i cant get it
Answer:
Let's define the cost of the cheaper game as X, and the cost of the pricer game as Y.
The total cost of both games is:
X + Y
We know that both games cost just above AED 80
Then:
X + Y > AED 80
From this, we want to prove that at least one of the games costed more than AED 40.
Now let's play with the possible prices of X, there are two possible cases:
X is larger than AED 40
X is equal to or smaller than AED 40.
If X is more than AED 40, then we have a game that costed more than AED 40.
If X is less than or equal to AED 40, then:
X ≥ AED 40
Now let's take the maximum value of X in this scenario, this is:
X = AED 40
Replacing this in the first inequality, we get:
X + Y > AED 80
Replacing the value of X we get:
AED 40 + Y > AED 80
Y > AED 80 - AED 40
Y > AED 40
So when X is equal or smaller than AED 40, the value of Y is larger than AED 40.
So we proven that in all the possible cases, at least one of the two games costs more than AED 40.
the average length of a doves egg is 7 1/2 inches. the average length of a ravens egg is 6/10 inches. about how many more inches is the doves egg to the ravens
Answer:
7 1/10 inch
Step-by-step explanation:
Using the graph below, calculate the average rate of change for f(x) from
x = 0 to x =2
1) -4
2) -2
3) 2
4) 4
Answer:
4
Step-by-step explanation:
Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]
Where,
a = 0,
f(a) = f(0) = -2 (from the graph given)
b = 2,
f(b) = f(2) = 5 (from the graph)
Plug in the values
Average rate of change = [tex] \frac{5 - (-2)}{2 - 0} [/tex]
[tex] = \frac{7}{2} [/tex]

The answer to the equation is 2.5
Which equation has the same solution as x2 + 16x – 11 = 4?
Answer:
x^2 + 16x - 15 = 0.
Step-by-step explanation:
x^2 + 16x – 11 = 4 Subtract 4 from both sides:
x^2 + 16x - 15 = 0 is one equation with the same roots.
Also any equation which is a multiple of the above will have the same roots. For example if we multiply by 3:
3x^2 + 48x - 45 = 0.

Find the exact values of csc and sec
Answer:
cosec theta = 5/4
sec theta = 5/3
Step-by-step explanation:
Given that;
cot θ = 3/4
1/tanθ = 3/4
tanθ = 4/3
since tanθ = opp/adj
opp = 4
adj = 3
hyp^2 = 4^2 + 3^2
hyp^2 = 16+9
hyp^2 = 25
hyp = √25
hyp = 5
sin theta= opp/hyp
sin theta = 4/5
cosec theta = 1/sin theta
cosec theta = 1/(4/5)
cosec theta = 5/4
Get sec theta;
sec theta = 1/costheta
sec theta = 1/(3/5)
sec theta = 5/3
Write x^3- 7x + 7x^5 - 19 + x^2
in standard form.
A. -19 + 7x5 - 7x + x3 + x2
B. x3 – 7x + 7x5 – 19 + x2
0
C. 7x5 + x3 + x2 - 7x - 19
O D. -19 - 7x + x2 + x + 7x5
Answer:
C
Step-by-step explanation:
A polynomial in standard form is first term, variable with largest exponent followed by decreasing exponents to the last term, the constant
Given
x³ - 7x + 7[tex]x^{5}[/tex] - 19 + x² ← rearrange terms
= 7[tex]x^{5}[/tex] + x³ + x² - 7x - 19 ← in standard form → C
Write two numbers that multiply to the value on top and add to the value on bottom. -60−60 -4−4 \times× ++
Answer:
The two numbers are 6 and -10
Step-by-step explanation:
Given
[tex]Product = -60[/tex]
[tex]Sum =-4[/tex]
Required
Two numbers that satisfy the above
Let the two numbers be x and y.
So:
[tex]x * y = -60[/tex]
[tex]x + y = -4[/tex]
Make x the subject
[tex]x = -4 - y[/tex]
Substitute [tex]x = -4 - y[/tex] in [tex]x * y = -60[/tex]
[tex](-4 -y) * y = -60[/tex]
Open bracket
[tex]-4y -y^2 = -60[/tex]
Rewrite as:
[tex]y^2 + 4y - 60 = 0[/tex]
Split
[tex]y^2 + 10y - 6y - 60 = 0[/tex]
Factorize
[tex]y(y + 10) - 6(y + 10) = 0[/tex]
Factor out y + 10
[tex](y - 6) (y + 10) = 0[/tex]
Solve for y
[tex]y -6=0\ or\ y+10=0[/tex]
[tex]y =6\ or\ y=-10[/tex]
Recall that:
[tex]x = -4 - y[/tex]
So:
[tex]x = -4-6= -10[/tex]
or
[tex]x = -4--10= 6[/tex]
So:
[tex]y =6\ or\ y=-10[/tex]
[tex]x = -10\ or\ x =6[/tex]
The two numbers are 6 and -10
Henri buys 126 inches of a fabric that costs $12 for each yard. How much dos Henri pay for the fabric
Answer: $47.28
Step-by-step explanation:
There are 126 inches of fabric.
You need to convert this to yard as that is the pricing unit.
1 yard = 36 inches
126 inches is:
= 126/32
= 3.94 yards
Cost is $12 per yard so Henry pays:
= 12 * 3.94
= $47.28
Bob went on 8 hikes.
The hikes were: 2 miles, 5 miles, 1 miles, 5 miles, 1 miles, 2 miles, 3 miles, 4 miles
What was the range of the lengths of Bob's hikes?
2 miles
3 miles
4 miles
5 miles
The range is the difference between the longest hike and the shortest hike.
Longest = 5
Shortest = 1
Range = 5-1 = 4 miles

The temperature increased by 10°F.
Step-by-step explanation:
To solve this question, solve this equation:
[tex]-6+X=4[/tex]
Flip the equation so it is easier to solve:
[tex]4-(-6)=X[/tex]
Two negatives = A positive so:
[tex]4+6=X[/tex]
Then, add to solve the equation:
[tex]10=X[/tex]
The temperature increased by 10.
Find the volume of a right rectangular prism if the dimensions of the base are 4 centimeters by 9 centimeters and the height is 11 centimeters.
Answer:
396 cubic centimeters
Step-by-step explanation:
Given that
The dimension of the base is 4 centimeter by 9 centimeter and the height is 11 centimeter
We need to find out the volume of the right rectangular prism
We need to apply the following formula
As we know that
Volume = lwh
here
l denotes the length
w denotes the width
And, h denotes the height
= (4) (9) (11)
= 396 cubic centimeters
Answer:
A 396 cm^3 is correct

Here is a diagram and its corresponding equation. Find the solution to the equation and explain your reasoning 38 x+7 x+7 x+7 x+7 4(x + 7) = 38
Answer:
x = (-158)/87
Step-by-step explanation:
Solve for x:
38 x + 7 x + 7 x + 7 x + 7×4 (x + 7) = 38
Hint: | Multiply 7 and 4 together.
7×4 = 28:
38 x + 7 x + 7 x + 7 x + 28 (x + 7) = 38
Hint: | Group like terms in 38 x + 7 x + 7 x + 7 x + 28 (x + 7).
Grouping like terms, 38 x + 7 x + 7 x + 7 x + 28 (x + 7) = 28 (x + 7) + (38 x + 7 x + 7 x + 7 x):
28 (x + 7) + (38 x + 7 x + 7 x + 7 x) = 38
Hint: | Add like terms in 38 x + 7 x + 7 x + 7 x.
38 x + 7 x + 7 x + 7 x = 59 x:
28 (x + 7) + 59 x = 38
Hint: | Distribute 28 over x + 7.
28 (x + 7) = 28 x + 196:
28 x + 196 + 59 x = 38
Hint: | Add like terms in 59 x + 28 x + 196.
28 x + 59 x = 87 x:
87 x + 196 = 38
Hint: | Isolate terms with x to the left hand side.
Subtract 196 from both sides:
87 x + (196 - 196) = 38 - 196
Hint: | Look for the difference of two identical terms.
196 - 196 = 0:
87 x = 38 - 196
Hint: | Evaluate 38 - 196.
38 - 196 = -158:
87 x = -158
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 87 x = -158 by 87:
(87 x)/87 = (-158)/87
Hint: | Any nonzero number divided by itself is one.
87/87 = 1:
Answer: x = (-158)/87

Complete Question
What is the area of the parallelogram?
Slant Height = 21 cm
Height = 15 cm
Base = 20 cm
Answer:
300cm²
Step-by-step explanation:
The formula for the area of the parallelogram = Base × Height
Base = 20cm
Height = 15cm
Area = Base × Height
= 20cm × 15cm
= 300 cm²
Therefore, the area of the parallelogram is 300 cm²
Answer:B!300 cm!

An airplane altitude in feet during its descend can be found using the function f(x)=-200x+20,000. After new government regulations become law the descent is now modeled by the function g(x)=-200x+20,500. Which statement describes the change?
Answer:
The airplane starts its descent from an altitude 500 feet higher.
Step-by-step explanation:
Given that:
F(x) = - 200x+20,000
g(x) = -200x+20,500
The functions are written in slope intercept format :
With a negative slope, the intercept gives the point which the rate of change begins in the vertical axis :
The slope is -200 ; which means that the descent rate of the airplane is 200
The intercept value however changes from 20,000 in f(x) to 20500 in g(x). This means that the height at which descent starts is now at a height of 20500 which is (20500 - 20000) = 500 miles higher than before.
