Answer:
7.7u - 5.1v + 14.5w
Step-by-step explanation:
Given length:
Side A = (1.2u+1.8v) centimeters,
Side B = (6.5u+8.7w) centimeters
Side C = (5.8w-6.9v) centimeters
Perimeter of a triangle = side A + side B + side C
= (1.2u+1.8v) + (6.5u+8.7w) + (5.8w-6.9v)
= 1.2u + 1.8v + 6.5u + 8.7w + 5.8w - 6.9v
Collect like terms
= 1.2u + 6.5u + 1.8v - 6.9v + 8.7w + 5.8w
= 7.7u - 5.1v + 14.5w
Therefore, the perimeter of the triangle is 7.7u - 5.1v + 14.5w

What is 3/4 times 1/8=
Answer:
The answer should be 3/22.
Step-by-step explanation:
To multiply the fractions, multiply the numerators and denominators separately.
3 times 1 over 4 times 8,
Multiply straight across,
Answer should be 3/22
The 3/4 times 1/8 equals 3/32.
To calculate the product of fractions, you multiply the numerators together to get the numerator of the result, and multiply the denominators together to get the denominator of the result.
For 3/4 times 1/8:
Numerator: 3 × 1 = 3
Denominator: 4 × 8 = 32

Two years ago, Rita was three times older than Cheryl. In 3 years, Rita will be twice older than Cheryl. How old are the girls now?
Answer:
Cheryl's age = x = 7 years
Rita's age = y = 17 years
Step-by-step explanation:
Let
Cheryl's age = x
Rita's age = y
Two years ago, Rita was three times older than Cheryl
(y - 2) = 3(x - 2)
y - 2 = 3x - 6
y = 3x - 6 + 2
= 3x - 4
y = 3x - 4
In 3 years, Rita will be twice older than Cheryl
(y + 3) = 2(x + 3)
y + 3 = 2x + 6
y = 2x + 6 - 3
= 2x + 3
y = 2x + 3
Equate both equations
3x - 4 = 2x + 3
Collect like terms
3x - 2x = 3 + 4
x = 7 years
Substitute x = 7 into
y = 2x + 3
= 2(7) + 3
= 14 + 3
= 17
y = 17 years
Cheryl's age = x = 7 years
Rita's age = y = 17 years
Rose bought some spinach she used 3/5 of the spinach on a pan of spinach pie for a party and 3/4 of the remaining spinach for a pan for her family she used the rest to make a salad. If rose used 3 pounds of spinach to make the pan of spinach pie for the party how many pounds of spinach did rose use to make the saled
Answer:
Total pounds of spinach = 5 pounds
Pounds used for salad = 0.5 pounds
Step-by-step explanation:
Let
Total spinach = x
She used pan of spinach pie for a party = 3/5x
Remaining spinach = x - 3/5x
= 5x-3x/5
= 2/5x
She used 3/4 of the remaining spinach for a pan for her family
3/4 of 2/5x
= 3/4 × 2/5x
= 6/20x
= 3/10x
she used the rest to make a salad.
Salad = x - (3/5)x - (3/10)x
= (1 - 3/5 - 3/10)x
= (10-6-3/10)x
= 1/10x
If rose used 3 pounds of spinach to make the pan of spinach pie for the party how many pounds of spinach did rose use to make the saled
She used pan of spinach pie for a party = 3/5x
3/5x = 3 pounds
Divide both sides by 3/5
x = 3 ÷ 3/5
= 3 × 5/3
x = 5 pounds
Salad = 1/10x
= 1/10 * 5
= 5/10
= 0.5 pounds

On her last science test, Mariah missed four questions. For those questions, she received a total of -20 points. On the retake, Mariah missed a quarter of the number of questions that she missed the first time. If the tests were scored the same way, how many points did she receive for missing questions on the retake?
-5
-10
-80
-16
Answer:
5
Step-by-step explanation:
in the beginning, she missed 4 questions and received -20 points. it means that each question missed is equal to -5 points.
So, finally, when she missed 1/4 of the four questions, it means that she missed only one question. So, she only received -5 points
Elene went to a store where you can scoop your own popcorn and buy as much as you want. She bought 10 ounces of spicy popcorn for 2.50. How much does popcorn cost per ounce? How much popcorn can you buy per dollar? Write two different equations that represent this situation. Use for ounces of popcorn and for cost in dollars.
Answer: See explanation
Step-by-step explanation:
Fron the question, we are informed that she bought 10 ounces of spicy popcorn for $2.50.
a. How much does popcorn cost per ounce?
1 ounce of popcorn = $2.50/10 = $0.25
b. How much popcorn can you buy per dollar?
Since 1 ounce of popcorn cost $0.25, $1 can buy popcorn worth:
= $1/$0.25
= 4 ounce of popcorn.
The relationship between the ounce of popcorn and the amount spent is an illustration of a linear function.
The cost per ounce is $0.25The amount of popcorn for $1 is 4 ouncesFrom the question, we have:
[tex]\mathbf{10oz - \$2.50}[/tex]
(a) The cost per ounce
To do this, we simply divide both sides by 10
[tex]\mathbf{Cost = \frac{\$2.50}{10oz}}[/tex]
[tex]\mathbf{Cost = \$0.25/oz}[/tex]
Hence, the cost per ounce is $0.25
(b) Popcorn for $1
To do this, we simply divide both sides by 2.5
[tex]\mathbf{Popcorn- \frac{10oz}{\$2.50}}[/tex]
[tex]\mathbf{Popcorn- 4oz/\$}[/tex]
Hence, the amount of popcorn for $1 is 4 ounces
(c) Represent as equations
In (a), the cost per ounce is $0.25.
So, the equation is:
[tex]\mathbf{y = 0.25x}[/tex]
In (b), the amount of popcorn for $1 is 4 ounces
So, the equation is:
[tex]\mathbf{x = 4y}[/tex]
Where: x represents the size of popcorn, and y represents the cost.

X^2 +6x+30 in vertex form
Answer:
Step-by-step explanation:
Factoring x2-6x-30
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -30
Step-1 : Multiply the coefficient of the first term by the constant 1 • -30 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is -6 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7
-2 + 15 = 13

Area is Length x width.
Area = 4x * 5
Area = 20x
Replace A in the inequality:
Now you have 100 <= 20x <= 1,000
Now solve for x by dividing all 3 by 20:
5 <= x <=50
Check to see if they are viable:
4(5) x 5 = 20 x 5 = 100
4(50) x 5 = 200 x 5 = 1,000
Since the lowest number equals 100 and the largest number equals 1,000 all values of x would be viable. The answer is YES.

What is the length of TH, when T (6, 9) and H (-4, -1)?
Answer:
d = 10 sqrt(2)
Step-by-step explanation:
The distance formula is
d = sqrt( (y2-y1) ^2 + ( x2-x1)^2)
d = sqrt( (-1-9) ^2 + ( -4-6)^2)
d = sqrt( (-10) ^2 + ( -10)^2)
d = sqrt( 100+100)
d = sqrt(200)
d = sqrt( 200*2)
d = sqrt(100) sqrt(2)
d = 10 sqrt(2)
