Marco walked 27/100 kilometers to the park.Then he walked 1/10 kilometer to the library. What fraction of a kilometer did he walk in all?
Answer: 37/100
Step-by-step explanation:
The fraction of a kilometer that he walked in all would be the sum of 27/100 and 1/10.
To add them, first find the lowest common multiple of both denominators. This number is 100 so will be the denominator.
Divide 100 by each denominator and multiply it by the numerator:
= (27 + 10) / 100
= 37/100
Note: 100/10 = 10
= 10 * 1 = 10 which is the second numerator.

100 students are interviewed to see which of biology, chemistry or physics they prefer.
72 of the students are girls. 34 of the girls like biology best.
11 of the boys prefer physics.
24 out of the 27 who prefer chemistry are girls.
What percentage of the students prefer biology?
Answer:
62%
Step-by-step explanation:
34 girls like biology
? boys like biology
It is 34%≤
27% Prefer chemistry
11% prefer physics
27 + 11 = 38
100 - 38 = 62

Andre has a summer job selling magazine subscriptions. He earns $25 per week plus $3 for every subscription he sells. Andre hopes to make at least enough money this week to buy a new pair of soccer cleats. Let `n` represent the number of magazine subscriptions Andre sells this week. Write an algebraic expression for the amount of money he makes this week.
Answer:
C = 25 + 3n
Step-by-step explanation:
Andre has a summer job selling magazine subscriptions.
We are told that:
Andy earns $25 per week plus $3 for every subscription he sells.
Let us represent
C = Total amount of money he makes this week
n = the number of magazine subscriptions Andre sells this week.
Hence, Our Algebraic expression =
C = $25 + $3 × n
C = 25 + 3n

What is her average from Macy scores
Answer: 85.2
Step-by-step explanation:
The answer is correct because, to find your grades your bassicaly just looking for the mean. To find the mean you have to take all the numbers and add them after you do that you have to divide how ever much numbers you added. So in this case we do 90 plus 76 plus 88 plus 80 plus 92. That equals 426, and since we added five numbers we divide the answer by 5 and that equals 85.2.
Hope This Helps!

solve for x. round your answer to the nearest tenth if necassary.
Answer:
32.9 degrees
Step-by-step explanation:
cos (x) = 21/25
cos^1 (21/25)
= 32.856 --> round to 32.9
Answer:
32.9°
Step-by-step explanation:
You can see that relative to the angle that is x, we are given the side lengths that are adjacent and the hypotenuse. The trig function associated with this is cosine, and we get:
cos(x) = adj / hyp --> 21 / 25
To find x as the angle, we use the function arccosine,
x = arccosine(21/25)
x = 32.85988038°
And this rounds up to 32.9°

The area of the parallelogram below is___square meters
Answer:
48 m^2
Step-by-step explanation:
Since this is a parallelogram, you can think of it as taking the triangle off of the left side and reattaching it on the right side to make a rectangle. After you visualize it as a rectangle, you just have to multiply 8 by 6 to get 48 meters squared.

Answer:
they look like their curved at about 70? 65? and they would be the same
Step-by-step explanation:
Answer: Both C and D are 76
Step-by-step explanation:
Because this is a isosceles triangle both C and D are the same. Subtract 28 from 180 and you get 152. So D and C combined equals to 152 so divide that by 2 an you get 76.
What is the surface area?
Find the surface Area?
Answer:
[tex]150 km^{2}[/tex]
Step-by-step explanation:
Use the surface area equation of cylinder: [tex]A = 2\pi rh + 2\pi r^{2}[/tex]
The diameter is 6 km but you need the radius for the formula, so you divide the diameter by 2.
6÷2 = 3 --> r = 3
You already know h, aka the height.
Plug everything into the equation.
Answer:
150.72
Step-by-step explanation:
im usin 3.14 as pi btw
the term net means like imagine you unfold the shape like the walls of the shape are paper. its now a 2d net, which includes a rectangle and two circles.
so, surface area of a circle is pi r^2 so 3.14 * 3 * 3 = 28.26
times two cause theres two circles; top and bottom :3
56.52 = 28.26 * 2
rentangle surface area = h*l
the height of the rectangle is 5 and the length is the circumference of the circle
circumference is 2*3.14*r, which in this problem, is 3
2*3.14*3 = 18.84
now, h*l is 18.84*5 = 94.2
94.2 + 56.52 = 150.72
Is this inequality true or false?
5v > 25, v = 3
Answer:
False
Step-by-step explanation: 5x3 is 15 and 25 is greater than 15 so the inequality is false.

Answer:
1) C: 113 m
2) C: 572.3 m²
3) B: 61.2 cm²
4) A: $2.2
6) C: 756 yd³
8) D: 3402 mm²
9) A: 25x + 125 < 500
Step-by-step explanation:
1) Formula for circumference of circle is;
C = 2πr
radius; r = 18 m
C = 2π × 18
C ≈ 113 m
2) Formula for area of a circle is;
A = πr²
Here we have diameter; d = 27
Thus, radius; r = 27/2 = 13.5 m
A = π × 13.5²
A = 3.14 × 13.5²
A ≈ 572.3 m²
3) The diameter of the semicircle is parallel to the base of the rhombus. Thus, diameter; d = 7 cm
Thus, r = 7/2 = 3.5 cm
Area of semi circle = ½πr² = ½ × π × 3.5² = 19.2 cm²
Area of rhombus = base x height = 7 × 6 = 42 cm²
Total area of object = 42 + 19.2 = 61.2 cm²
4) Cost of banana per pound = $0.4 per pound
Amount of banana bought = 5.5 pound
Amount spent = 0.4 × 5.5 = $2.2
6) Volume of triangular prism is;
V = ½bhl
b = 12 yd
h = 7 yd
L = 18 yd
Thus;
V = ½ × 12 × 7 × 18
V = 756 yd³
8) Volume of cuboid at the base;
V1 = lbh = 25 × 9 × 9 = 2025 mm²
Volume of cuboid at top;
V2 = 9 × 9 × 9 = 729 mm²
Volume of triangular prism;
V3 = ½bhl = ½ × 9 × 9 × (25 - 9) = ½ × 81 × 16 = 648 mm²
Total volume = 2025 + 729 + 648 = 3402 mm²
9) Cost per class; $25 per class
Charge for the supplies = $125
He doesn't want to spend more than $500.
Thus;
25x + 125 < 500

1/3 x 1/4 = ?????????
Answer:
1/12
Step-by-step explanation:
1/4 X 1/3 = 1/12
Answer:
1/12
Step-by-step explanation:
When multiplying fractions, you multiply it like normal numbers, so 1 is multiplied by 1, and 3 is multiplied by 4.
For example:
3/4 x 9/10 would be equal to 27/40 because the 3 is multiplied by 9 and 4 is multiplied by 10.
3 x 9 = 27
4 x 10 40
27/40
Therefore on your question it would be 1/12.
