Δ FCD is a right triangle ( 3² + 4² + 5² ).
10 : EB = 5 : 3
5 EB = 30
EB = 6
With Pythagorean theorem:
CE² = 10² - 6² = 10 - 36 = 64
CE = 8
ED = 5
AB = 2 · 5 = 10
Answer: The length of the side AB is 10.

Tamiku [17]

Answer:

The best and most correct answer among the choices provided by your question is the third choice or letter C. The total number of hours is 17.

For h>7

C=210+20(h-7)

C=210+20h-140

C=20h+70, h>7

410=20h+70

20h=340

h=17 hours

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC b

irakobra [83]

Answer:

Step 2; it should be m∠w + m∠z = 180 degrees (supplementary angles)

Step-by-step explanation:

Step 1: m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle)

Step 2: m∠w − m∠z = 90 degrees (corresponding angles)

We are adding the angles to form a straight line which is 180 degrees

Step 3: Therefore, m∠x + m∠y + m∠z = m∠w + m∠z

Step 4: So, m∠x + m∠y = m∠w

Mike wants to make meatloaf. His recipe

Eduardwww [97]

Answer:

1 1/4 pounds.

Step-by-step explanation:

The ratio of beef to pork is 3:1. What this means is that out of the 5 pounds of meat Mike will use for his meatloaf, 3 parts of it will be beef and 1 part will be pork, which gives us four parts total.

So the ratio of pork to total meat would be 1:4, or 1/4. Now we need to multiply 5 by 1/4 in order to get the amount of pork. Since multiplying by 1/4 is the same as dividing by 4, we can just divide to make things simpler.

$p = 5 \times \frac{1}{4} \\ p = \frac{5}{4}$

The answer, expressed as an improper fraction, is 5/4. However, the question is asking for a mixed number, so we'll need to convert our answer. We just need to subtract from the numerator so that the fraction is equal to 4/4.

$\frac{5}{4} - \frac{4}{4} = \frac{1}{4}$

Since 4/4 is equivalent to 1, we'll just simplify this further.

$p = \frac{4}{4} + \frac{1}{4} \\ p = 1 \frac{1}{4}$
