Answer:
(-1/3 )(1/4)=(-1/12)
Step-by-step explanation:
(-1/3 )(1/4)
For fraction multiplication, multiply the numerators and then multiply the denominators to get
(-1/3 )(1/4)=(-1/12)
This fraction cannot be reduced.
Therefore:
(-1/3 )(1/4)=(-1/12)
4. Order the sides of each triangle from shortest to longest.
X
85°
41°
54°
W
V
1. Longest
a.
VW
2. Middle
b. WX
3. Shortest
XV
c.
Answer:
XV < XW < WV
Step-by-step explanation:
The side lengths are proportional to angles they see
The side that sees the largest angle has longest measurement and the one that sees smallest angle would be shortest therefore we can order sides from shortest to longest like this :
XV < XW < WV

h(x)
=
3x2 – 2x + 13
h(3) = [?]
Be sure to simplify your answer.
Answer:
34
Step-by-step explanation:
h(x)=3x² – 2x + 13
By replacing x with 3, we get
h(3)=3×3² – 2×3 + 13
=3×9-6+13
=27+7
=34
Isolate the variable by adding a constant to each side of the equation 4(x-5)=25
Answer:
ummm I think u want the answer x= 11 1/4
Answer:
x = 45/4
Step-by-step explanation:
4(x - 5) = 25
4x - 20 = 25
4x - 20 + 20 = 25 + 20
4x = 45
4x/4 = 45/4
x = 45/4
Rachel took a total of 21 quizzes over the course of 3 weeks. After attending 10 weeks of
school this quarter, how many quizzes will Rachel have taken in total? Solve using unit rates.
Answer:
70
Step-by-step explanation:
If 3 weeks, 21 quizzes was done
If 10 week, how many quizzes was done
So technically this is what the question is about
So let's count in 1 week, how many quizzes were done, to do that, just divide
21/3
= 7
Therefore we can take it as, in one week, 7 quizzes will be done
Therefore in 10 weeks
= 7 x 10
= 70

how to calculate area of coloured part
plsss help
Answer:
Step-by-step explanation:
The need is to find the area of the elongated plus sign inside the rectangle. The area of the rectangle itself is not needed. That elongated plus sign is where we will run into trouble. The center of that plus sign is included in both the vertical strip and the horizontal strip. So when we go to find the area of the plus sign, we include the center in one or the other, NOT BOTH. I included the area in the vertical strip so I eliminated it in the horizontal strip, creating 2 shorter strips on either side of the center.
The area for the vertical strip, including the center:
A = 3 * 26 (3 is the width and 26 is the length)
A = 78 square meters
Now for the horizontal strip...
The horizontal strip minus the center is
14 - 3 = 11; divide that 11 in half and we get the length of each short horizontal strip on either side of the center to be 5.5 meters long. Therefore, each short strip measures 5.5 (we have 2 of them).
A = 3(5.5) + 3(5.5) and
A = 16.5 + 16.5
A = 33
The sum of the long vertical and the 2 shorter horizontal areas is
78 + 33 = 111
Therefore, the total area of the colored portion is 111 square meters.
Three painters worked 6 hours each at $35.50 per hour. They used
9 gallons of paint at $29.85 per gallon. Find the total charge.
Answer:
$907.65
Step-by-step explanation:
$35.50 for 6 hrs is $213 times 3 because of the 3 painters, which is $639. $29.85 times 9 is $268.65. Add together you get $907.65
Write the ratio as a fraction in the simplest form 26.1miles : 3.6hours
Answer:36 hours

Inverse equation
1. g(n)= 2+(n+2)^3
2. f(n)= 1/2n+3/2
Answer:
1
[tex]g(n) = 2 + {(n + 2)}^{3} [/tex]
let the inverse be m :
[tex]m = 2 + {(n + 2)}^{3} \\ {(n + 2)}^{3} = m - 2 \\ n + 2 = \sqrt[3]{(m - 2)} \\ n = \{ \sqrt[ 3]{(m - 2)} - 2 \}[/tex]
therefore:
[tex]{ \boxed{ \boxed{g {}^{ - 1}(n) = \{ \sqrt[3]{(n - 2)} - 2 \}}}}[/tex]
2.
[tex]f(n) = \frac{1}{2} n + \frac{3}{2} [/tex]
let inverse be x :
[tex]x = \frac{1}{2} n + \frac{3}{2} \\ \\ 2x = n + 3 \\ n = 2x - 3[/tex]
therefore:
[tex]{ \boxed{ \boxed{f {}^{ - 1}(n) = 2n - 3 }}}[/tex]

Community Gym charges a $40 membership fee and a $65 monthly fee. Workout Gym charges a $190 membership fee and a $55 monthly fee. After how many months will the total amount of money paid to both gyms be the same? What will the amount be?
Answer:
Step-by-step explanation:
65m + 40 = 55m + 190
65m - 55m = 190 - 40
10m = 150
m = 15 months

the distance between the base of the tree and the base of the building is:
please
my guess is "15m" is it correct ?
Explanation:
Apply the pythagorean theorem to find the missing side.
[tex]a^2 + b^2 = c^2\\\\x^2 + 20^2 = 25^2\\\\x^2 + 400 = 625\\\\x^2 = 625-400\\\\x^2 = 225\\\\x = \sqrt{225}\\\\x = 15[/tex]
The horizontal leg of the right triangle is 15 meters long. This is the distance from the base of the tree to the base of the building.
Side note: This right triangle is based off the 3-4-5 right triangle. It has been scaled up by a factor of 5.
