Answer:
Let Musa's mark be = m
Emmanuel's mark be = e
Faith's mark be = f
m = e + 7
e = 25
m = 25 + 7 = 32
f = 1/4 m + e
f = (1/4 × 32) + 25
f = 8 + 25
f = 33

A wooden roller is 1 m long and 8 cm in diameter. Find it's mass in grams if 1cm³ of the wood has a mass of 0.7 g
Answer:
1120π grams
==> 3518.58 grams using value of π = 3.14159 or
==> 3520 grams using value of π = 22/7
Step-by-step explanation:
Volume of a cylinder = πr²l where r is the radius of the base and h is the length of cylinder
The diameter of the cylinder, d = 8cm and radius = d/2 = 4cm
Length = 1 meter = 100 cm
Here, volume V = π.4².100 = π x 16 x 100 = 1600π cm³
Since 1 cm³ has a mass of 0.7gm total mass
M = 0.7V = (0.7)1600π =1120π gm
Using the ratio 22/7 for pi we get
M = 1120 x 22/7 = 3520 g
If we use the more accurate value of π as 3.14159 then we get
M = 1120 x 3.14.159 = 3518.58 g which is more accurate

Silas is researching the cost of a specific souvenir he wants to buy on his international trip. Use the table to answer the question.
Answer:
Egypt.
Step-by-step explanation:
We need to set up our conversion factors for each currency.
British Pounds and Egyptian Pounds:
0.83 £ (Europe) = 1 U.S. Dollar
18 E£ (Egypt) = 1 U.S. Dollar
Cost of a Souvenir in Europe:
The cost of souvenir in Europe is 13£. Using our conversion rate, we get
[tex]13\pounds \cdot \frac{\$1}{0.83 \pounds}=\$15.66[/tex]
Cost of a Souvenir in Egypt:
The cost of a souvenir in Egypt is 342 E£. So we have
[tex]342 \text{ E}\pounds\cdot \frac{\$1}{18 \text{ E}\pounds}=\$19[/tex]
Based on our calculations, it is cheaper to buy a souvenir in Europe than in Egypt.
What is the surface area of this 3d character based off the illustration. Can you provide explanation. Thank you.
The surface area of this 3d character based off the illustration will be 289.
How to explain the surface area?It should be noted that the surface area simply means the amount of space that covers the outside of a shape.
Here the length of the shape is 17 and the width is also 17 as well. It should be noted that the width and length are determined by looking at the axis of the shapes drawn.
In this case, the area will be:
Length × Width
= 17 × 17
= 289
In conclusion, the surface area is 289.

The ratio of black bags to blue bags is 5to 3 if there are a total of 10 black bags ,then how many blue bags are there
Answer:
6
Step-by-step explanation:
We can think of the 10 black bags as 2 sets of 5-black bags (10 divided into groups of 5; 10 / 5 ; is 2 groups/sets). So, we would also have two sets of 3 (3 x 2 = 6), or 6 bags.

For the arithmetic sequence beginning with the terms (11, 17, 23, 29, 35), what is the sum of
the first 17 terms?
a.) 1116
b.) 1003
c.) 1235
d.) 896
Option B is the correct answer.
The sum of 17 terms of the given arithmetic sequence is 1003.
What is Arithmetic Sequence?An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k.
Here, given sequence :
11, 17, 23, 29, 35, ......
first term a = 11
common difference d = 17 - 11 = 6
n = 17
Sₙ = n/2 {2a + (n-1)d}
S₁₇ = 17/2 { 2 X 11 + (17-1)X6}
S₁₇ = 17/2 { 22 + 16 X 6}
S₁₇ = 17/2 X 118
S₁₇ = 17 X 59
S₁₇ = 1003
Thus, the sum of 17 terms of the given arithmetic sequence is 1003.
