Answer:
$16
Step-by-step explanation:
Answer:
Estimate: $16
Exact amount: $15.98
Step-by-step explanation:
To find the estimate amount of money she has left, we will add everything up and subtract it from $45.12.
$7.89 + $21.25 = $29.14
$45.12 - $29.14 = 15.98
Now lets round your answer to $16. Therefore, the estimated amount that she has left is $16. And based on the calculations above, we can see that the exact amount of money she has left is $15.98.

They are similar because they both have like terms in parenthesis.
Step-by-step explanation:
As long as you have like terms, the equation is the same. You never have to worry about the number before the variable being the same. As long as the variable is the same, you have like terms and that is like terms in the equation. TO SUM IT UP: They both have like terms and that is why they are similar.

Scale factor = 1 : 7
a)Let the length of the house in the scale drawing = x
1:7 :: x : 21
Product of means = Product of extremes
7*x = 1* 21
x = [tex]\frac{1*21}{7}[/tex]
x = 3
Length of the house in the scale drawing = 3 in
b) Height of the real house =y
1 : 7 :: 4 : y
Product of extremes = product of means
1 * y = 7*4
y = 7*4
y = 28
Height of real house = 28 feet

Gabby figures that her troop increased by about 19.4%
Describe and then correct the error Gabby made in finding the percent of change.
Pick what Gabby did wrong.
The real percent of change is:
Answers
Answer: 24%
Step-by-step explanation:
Since we are informed that the Girl Scout Troop started with 25 girls and at the end of the year party there were 31 girls. The percentage change will be:
= (31 - 25) / 25 × 100
= 6/25 × 100
= 24%
The error that Gabby made was that she used 31 as the base. This is expressed below:
= 31 - 25) / 31 × 100
= 6/31 × 100
= 19.4%

When xb= 12, y = 8. Find x when y = 12
Answers
Answer:
If it is direct proportionality, then y = kx where k is a constant. Use the given information to find k:
8 = k(12) ⇒ k = 8/12 = 2/3
y = (2/3) x
For y = 12,
12 = (2/3) x ⇒ x = (3/2)*12 = 18
x = 18 when y = 12

please help me with this angle question :)
Answers
Answer:
its an acute angle
Step-by-step explanation:
its an acute angle be cause its small than a right angle
Answer:
angle AED = 70 degrees
angle x = 10 degrees
Step-by-step explanation:
since angle ABD = 110 degrees, major arc AED = 2(110) = 220 degrees
since angle ADB = 40 degrees, minor arc AB = 2(40) = 80 degrees
minor arc BD = 360 - 220 - 80 = 60 degrees
arc AB + arc BD = arc ABD
arc ABD = 80 + 60 = 140 degrees
angle AED = 1/2 (140) = 70 degrees
angle EAD = angle AED because isosceles
arc ED = 2(70) = 140 degrees
arc AE = arc AED - arc ED = 80 degrees
angle x = 1/2(arc AE - arc BD) = 1/2(80 -60) = 10 degrees

Answer:
m<E = [tex]77^{o}[/tex]
Step-by-step explanation:
From the diagram, ΔACE and ΔBDE are similar. So that comparing its angles, we have;
(8x + 4) = (9x - 5)
8x + 4 = 9x - 5
5 + 4 = 9x - 8x
x = 9
Thus,
(8x + 4) = 8(9) + 4 = 76
(9x - 5) = 9(9) - 5 = 76
3x = 3(9) = 27
From ΔACE,
3x + (8x + 4) + m<E = 180 (sum of angles in a triangle)
27 + 76 + m<E = 180
m<E = 180 - 103
m<E = [tex]77^{o}[/tex]

A butcher has 15 and 3/4 pounds of steaks and portions them into 7 sealed packs. How many pounds does each pack of steak weigh? *
Answers
Answer:
9/4 or 2 and 1/4 pounds
Step-by-step explanation:
Convert 15 and 3/4 into an improper fraction
15*4+3 = 63
63/4
63/4 ÷ 7
9/4
Thus, each pack weighs 9/4 pounds
Answer:
2 1/4 pounds each
Step-by-step explanation:
Convert 15 1/4 into a decimal (15.75) then divide by seven (15.75 ÷ 7 = 2.25)
and then convert 2.25 back into a fraction, 25 is 1/4 of 100 so the answer is 2 1/4
