When a number, half of the number, and a third of the number are added together, the
Finger [1]

Step-by-step explanation:

Let the number be x.

Half of a number is x/2 and a third of the number is x/3

ATQ,

x+\dfrac{x}{2}+\dfrac{x}{3}=275\\\\\dfrac{6x+3x+2x}{6}=275\\\\\dfrac{11x}{6}=275\\\\x=\dfrac{275\times 6}{11}\\\\x=150

Frist no is 150

Second no is 150/2 = 75

Third no is 50

Need to find the number for a
Shalnov [3]
Answer to the first triangle: 15

To solve this we will use the Pythagorean theorem

Pythagorean theorem formula: a^{2} +  b^{2} =c^{2}

Lets do the first triangle. 

17 is the hypotenuse, so its going to replace c in the formula.

8 is the height and it is going to replace a in the formula.

a is what we are trying to find, so our b in the equation is going to be the unknown.

8^2 + b^2 = 17^2

64 + b^2 = 289



b^2 = 289 - 64

b^2 = 225

\sqrt{b^2}  =  \sqrt{225}

b = 15

now we know that the missing length in the first triangle (a) is 15

Can you solve the Other one?

Just comment if you need help on the other one.

A cube has a surface area of 150 <br> cm squared. Find the side length of the cube in cm.
puteri [66]

Answer:

Step-by-step explanation:

6 faces have an area of 150 cm^2

1 face has an area of 150/6 = 25 cm^2

The formula for the area of one face of a cube = s^2 which is the length of  a side squared.

s^2 = 25

sqrt(s^2) = sqrt(25)

s = 5

I have 5 questions. Please help.
Lady bird [3.3K]

Answer:

1. 1

2. 5/8

3. 3/4

4. 7/8

5. 5/8

Step-by-step explanation:

1. The denominators are the same, so just add the top numbers (the numerator), 1/7 + 6/7 = 7/7, which is 1.

2. The denominators are the same, so just add the top numbers (the numerator), 7/16+3/16=10/16. 10/16 can be divided by 2 to get 5/8.

3. 1/6=2/12. So, the new problem is 2/12+7/12. Add the numbers, and you get 9/12. Divide the top and bottom by 3, and your answer is 3/4.

4. 3/4=6/8. The new problem is 6/8+1/8. This is 7/8.

5. 1/4=2/8. The new problem is 2/8+3/8. 2+3 is 5, so your answer is 5/8.
