Answer:

Step-by-step explanation:

Because EF and BC are parallel, ΔEFD, and ΔBCD are similar. Because we know what CF and DF are, we can add their lengths together to get CD, which in this case is 44 units long. Then, we can divide the length of CD and DF to get the scale of ΔEFD, which is 6/11. Because ΔEFD and ΔBCD are similar, we can multiply the length of BD by 6/11 to get the length of ED, which turns out to be 30.

Please help I am horrible at math! Ye is riding home from a friend's house. After 5 minutes he is 4 miles from home, after 15 mi

vesna_86 [32]

Answer:

y=-0.2x+5. Correct choice: A)

Step-by-step explanation:

Modeling With Equations

Let's call x the number of minutes and y the distance from home. The correct model should meet both conditions:

After 5 minutes, Ye is 4 miles from home. This is the ordered pair (5,4)

After 15 minutes, Ye is 2 miles from home. This is the ordered pair (15,2)

A) y=-0.2x+5. Testing the first point (5,4): y=-0.2*5+5=4. Correct

Testing the second point (15,2): y=-0.2*15+5=2. Correct

This is the correct choice.

B) y=11/7x-27/7. Testing the first point: (5,4) y=11/7*5-27/7=4. Correct

Testing the second point (15,2). y=11/7*15-27/7=138/7. Incorrect

Incorrect choice.

C) This equation is equal to the choice B), thus this one is incorrect.

D) y=5x-0.2. The first point (5,4) yields to:

4=5*5-0.2=24.8 Incorrect.

Arrange from least to greatest, 4.3, 5.5, 6 1/6, 15/4, 4 3/8?

Sophie [7]

Here are the numbers
4.3 , 5.5 , 6 $\frac{1}{6}$ , $\frac{15}{4}$ , 4 $\frac{3}{8}$
I'm going to change them into fractions
In the fractions, divide the numerator by the denominator
$6\frac{1}{6}$ ⇔6.1666---
$\frac{15}{4}$ ⇔3.75
$4 \frac{3}{8}$ ⇔4.375
Now to arrange them from least to the greatest
$\frac{15}{4}$ , 4.3 , $4 \frac{3}{8}$ , 5.5 , $6\frac{1}{6}$
