Answer:
48.8
Step-by-step explanation: The equation for the area of a circle is π*r², since the base of a cylinder is a circle we take the equation of a circle and multiply the height of the cynlinder by using the equation π*r²*h to get the volume of a cylinder. In this case our factors are
π= 3.14
r²= 6.76
h=2.3
3.14*6.76*2.3=48.82072
rounded to the nearest tenth=48.8

In 1990 an egg cost 2c less than in 1991. In 1992 an egg cost 4c more than in 1991. The cost of 11 eggs in 1990 was the same as the cost of 8 eggs in 1992. Find the cost of an egg in 1991.
Answer:
18
Step-by-step explanation:
given that the eggs cost 16ct in 1990 and 22ct in 1992 you can calculate
16ct+2ct=18ct and 22ct-4ct=18ct

Here are the first four terms of a sequence: 3, 12, 48 and 192.
(a) Work out the common ratio for this sequence.
(b) Work out the nth term of this sequence.
Answer:
look below
Step-by-step explanation:
The common ratio is 1:4 because we are multiplying the previous number by 4
The nth term for this sequence is quite simple. To find the nth term, take the base, 3, and multiply by the nth 4th. This can be written as 3*4^n+1
I hope this helped!
It would be greatly appreciated if you marked this answer as brainliest!
Answer:
see explanation
Step-by-step explanation:
the sequence is geometric and has common ratio r
(a)
r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{12}{3}[/tex] = 4
(b)
the nth term of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
here a₁ = 3 and r = 4 , then

Think carefully about the angle relationship the following represents.
What is the value of ∠ZXY?
Answer:
55°
Step-by-step explanation:
Since ∠WXY has a square on ∠X, ∠WXY is a 90° angle. This means that the angles in between ∠WXY also sum up to 90°.
⇒ 35 + 4x + 7 = 90
⇒ 4x = 90 - 35 - 7
⇒ 4x = 48
⇒ x = 48/4 = 12
Substitute the value of x into the expression "4x + 7"
⇒ ∠ZXY = 4x + 7 = 4(12) + 7 = 48 + 7 = 55°
Answer:
We know that this is a 90° Angle.
We already have 35° so we subtract that from 90
90-35=55
So the value of ∠ZXY = 55°
Also, the value of X is equal to 12

A bakery sells white loaves and brown loaves.
One week, the ratio of the number of white loaves sold to the number of brown loaves
sold was 4:5
The bakery sold a total of 1584 loaves that week.
Work out how many brown loaves they sold.
Answer:
880 brown loaves
Step-by-step explanation:
Create a ratio of brown loaves to total loaves by adding the the current ratio, 4:5 together.
4 + 5 = 9.
Now create the new ration of brown loaves to total loaves.
5:9
Next make a proportion using brown (numerator) to total (denominator).
Then cross multiply and divide.
[tex]\frac{5}{9} = \frac{b}{1584}[/tex]
[tex]9b = 7920\\\frac{9b}{9} =\frac{7920}{9} \\b=880[/tex]
Let’s say that in these congruent triangles, the length of side AB in the first triangle is 6 feet. What is the length of side DE in the second triangle?
Answer:
6 feet
Step-by-step explanation:
Corresponding vertices of the congruent triangles are listed in the same order in the congruence statement. Given that ΔABC ≅ ΔDEF, that means vertices A and B correspond to vertices D and E.
Segment DE will have the same length as segment AB, 6 feet.

What value of x is in the solution set of 4x - 12 S 16 + 8x?
You gave little context, so here is a few solutions.
POSSIBLE #1:
assuming s is a variable
---> Simplify [tex]12S[/tex] × [tex]16[/tex] to [tex]192S[/tex]
[tex]4x-192S+8x[/tex]
---> Collect like terms.
[tex](4x+8x)-192S[/tex]
---> Simplify.
[tex]12x-192S[/tex]
POSSIBLE #2: (assuming s is not relevant)
Simplifying
4x + -12 = 16 + 8x
Reorder the terms:
-12 + 4x = 16 + 8x
Solving
-12 + 4x = 16 + 8x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8x' to each side of the equation.
-12 + 4x + -8x = 16 + 8x + -8x
Combine like terms: 4x + -8x = -4x
-12 + -4x = 16 + 8x + -8x
Combine like terms: 8x + -8x = 0
-12 + -4x = 16 + 0
-12 + -4x = 16
Add '12' to each side of the equation.
-12 + 12 + -4x = 16 + 12
Combine like terms: -12 + 12 = 0
0 + -4x = 16 + 12
-4x = 16 + 12
Combine like terms: 16 + 12 = 28
-4x = 28
Divide each side by '-4'.
x = -7
Simplifying
x = -7

Sasha is making custom designs using these small trapezoidal prisms. She wants to cover each of the 8 prisms in her current design in striped cloth on all sides. She has 3500 square centimeters of striped cloth.
Does Sasha have enough cloth to cover all 8 prisms in her current design?
Choose from the drop-down menus to correctly complete the statement.
The combined surface area of the prisms is cm², therefore Sasha have enough cloth for her current design.
Combined surface area for the 8 prisms is: 3,040 square centimeters.
3,500 cm² > 3,040 cm², therefore, Sasha has enough cloth for the design.
What is the Surface Area of a Trapezoidal Prism?Surface area = (b1 + b2)h + PH
Given the following dimensions:
b1 = 5 cmb2 = 15 cmHeight of trapezium (h) = 7 cmPerimeter of trapezium (P) = 15 + 10 + 10 + 5 = 40 cmHeight of prism (H) = 6 cmPlug in the values into SA = (b1 + b2)h + PH:
Surface area = (5 + 15)7 + (40)(6)
Surface area = 380 sq. cm.
Combined surface area for the 8 prisms = 380 × 8 = 3,040 square centimeters.
3,500 cm² > 3,040 cm², therefore, Sasha has enough cloth.

Step-by-step explanation:
7 + 6 = 13 (Length + Height)
13 x 5 = 65 side a (h + l)
15 x 13 = 195 side b (h+l)
10 x 6 = 60 side c x length
