Answer:
1. 32
4:4 is the same as 1:1 meaning each one gets the same
2. 40
put 1/7 equal to 5/x and cross multiply (1x=35)(35 male workers, so add 35 to 5 female workers)
3. 8
Multiply two by 4 since an hour is 15×4
4. 188
put the ratio 7/330 to 4/x (7x=1320)(x=188.57) since you can use part of a nail, round down to 188.
5. 5 1/2 pounds
multiply 1/4 by 22 which is 22/4. that is equal to 5.5
Answer:C
Step-by-step explanation:
Answer:
1/6
Step-by-step explanation:
To find the value of x that makes the equation true we isolate x on one side of the equation. Technically this is solving for x. The Division Property of Equality states that if we divide both sides of an equation by the same amount then we will have an equivalent equation. We can divide both sides of this equation by 36 to get x = 1/6
Answer:
9 and 8 are linear and 10 is non linear
Step-by-step explanation:
an = dn - c
The an stands for the nth term of the pattern. So a1 is the first term and a2 is the second term of the pattern. The d is the difference between each of the terms. The n stands for the term you're calculating. If you're calculating the third term, then n is 3. And c is a constant that you'll need to calculate.
For example, the linear number pattern of 1, 3, 5, 7, 9, … has an equation of:
an = 2n - 1.
Answer:
21 cm
Step-by-step explanation:
Call the triangle ABC, with the right angle at B, the hypotenuse AC=25, and the given leg AB=10. The altitude to the hypotenuse can be BD. Since the "other leg" is BC, we believe the question is asking for the length of DC.
The right triangles formed by the altitude are all similar to the original. That means ...
AD/AB = AB/AC . . . . . . ratio of short side to hypotenuse is a constant
Multiplying by AB and substituting the given numbers, we get ...
AD = AB²/AC = 10²/25
AD = 4
Then the segment DC is ...
DC = AC -AD = 25 -4
DC = 21 . . . . . centimeters
