The school cafeteria sells two types of wraps vegetarian and chicken the vegetarian wrap costs $1.00 and the chicken wrap costs $3.40 today they made $266.20 from the 103 wraps sold how many wraps sold were vegetarian
Answer:
35
Step-by-step explanation:
Let's make a system of equations for the vegetarian and chicken wraps; one for the total cost of them and one for the total amount sold.
Vegetarian wraps will be represented by variable v and chicken wraps will be represented by the variable c.
v + 3.40c = 266.20 v + c = 103Subtract these equations.
2.40c = 163.20Divide both sides by 2.40.
c = 68Substitute this value for c into the second equation.
v + (68) = 103Subtract 68 from both sides.
v = 35The number of vegetarian wraps sold amounted to 35 in total.
Answer :
The school cafeteria sold 35 vegetable wraps.Step-by-step explanation:
Let the count of vegetarian wraps be xLet the count of chicken wraps be y.Then for the count we have :
→ count of vegetarian wraps + count of chicken wraps = 103
→ x + y = 103......[Equation (i)]
Then for the cost we have :
→ ❲$1.00 * x❳ + ❲$3.40 * y❳ = $266.20
Dropping the dollar signs we get :
→ ❲1.00 * x❳ + ❲3.40 * y❳ = 266.20
→ x + 3.40y = 266.20.....[Equation (ii)]
Substracting equation (i) from equation (ii) we get :
→ 0 + 2.4y = 163.2
→ 2.4y = 163.2
→ y = 163.2 ÷ 2.4
→ y = 68
Now, subsitute the value of y = 68 in equation (i) we get :
→ x + y = 103
→ x + 68 = 103
→ x = 103 - 68
→ x = 35
Hence, the school cafeteria sold 35 vegetable wraps.Wyatt is saving up to buy a new bicycle. He already has $60 and can save an
additional $6 per week using money from his after school job. How much total money
would Wyatt have after 6 weeks of saving? Also, write an expression that represents
the amount of money Wyatt would have saved in w weeks.
Answer:
Expression: 6w+$60 Money: $99
Step-by-step explanation:
So, let's find the ammount for 6 weeks
We know he can make $6 per week, so we ned to multiply 6*$6 to get your answer
So, 6 ( weeks ) * 6 ( dollars) = $36 for 6 weeks
Then, we ned to add the $60 he already has saved up, so $60+$39=$99
For the equation, We know that we need to multioply the number of weeks by 6, as shown by how we solved the last problem
So, 6*w=6w
Then we need to add $60
So, we get 6w+$60 for the expression

Answer:
rv=1/2
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
Given
rv=1/c+rSolving for c
Its not clear what the denominator is: c or c+r so doing bothDenominator is c:
rv = 1/c + r1/c = rv - rc = 1/(rv - r)Denominator is c + r:
rv = 1/(c + r)rv(c + r) = 1rvc + r²v = 1rvc = 1 - r²vc = (1 - r²v)/rvor more simplified
c = 1/rv - rNote. If you know the answer it should help how to get it

11. Kelsey's garden on her farm was originally 20 feet long and 4 feet wide. She added
an addition onto her garden that was 12 feet long and 6 feet wide. If she wants to
use 100 square feet of the gardens total area to plant vegetables and the rest of the
area to plant fruits, how much space of the garden will the fruit plants take up?
Answer:
So, the original space of her garden was 20ftl + 4ftw. This makes her garden have a starting area of 80ft.
She then adds another 72ft (12ftl x 6ftw) which brings the total area to 152ft.
We have 152ft to work with here, if she wants to use 100 of those ft for vegetables, and the rest to plant fruits, we have to subtract 100 from 152 which gives us 52.
Answer:
The Fruits will take up 52ft of land.

The perimeter of a yard is 60 meters. The length is six less than twice the width. What are the dimensions of the yard?
Length = 18 meters,
Width = 12 meters
B
Length = 36 meters,
Width = 24 meters
C
Length = 24 meters,
Width = 36 meters
D
Length = 12 meters,
Width = 18 meters
Answer:
Length = 18 meters,
Width = 12 meters
Step-by-step explanation:=
Step one:
given data
perimeter= 60 meter
let the width be x
W=x
L=(2x-6)
Step two:
we know that perimeter of a rectangle is given as
P=2W+2L
60=2x+2(2x-6)
60=2x+4x-12
60=6x-12
collect like terms
6x= 60+12
6x=72
divide both sides by 6
x=72/6
x=12
Width is 12m
from L=(2x-6)
L=2*12-6
L=24-6
L=18m

A quality control inspector has drawn a sample of 19 light bulbs from a recent production lot. If the number of defective bulbs is 1 or less, the lot passes inspection. Suppose 30% of the bulbs in the lot are defective. What is the probability that the lot will pass inspection
Answer:
0.0016283
Step-by-step explanation:
Given that:
Proportion of defective bulbs, p = 30% = 0.3
Sample size, n = 19 bulbs
Probability that the lot will pass inspection :
P(none of the 19 is defective) Or P(only one of the 19 is defective)
P(none of the 19 is defective) = (1 - p) ^n = (1 - 0.3)^19 ; 0.7^19
0.7^19 = 0.0011398
P(only one of the 19 is defective) :
P(1 defective) * P(18 not defective )
(0.3) * (1 - 0.3)^18
0.3 * 0.7^18
0.3 * 0.001628413597910449 = 0.0004885
Hence,
P(none of the 19 is defective) + P(only one of the 19 is defective)
0.0011398 + 0.0004885) = 0.0016283

8. Have you ever heard the word tithe? It means a tenth or 10%. Leviticus 27:30 reads, "A tithe of

it is holy to the Lord." Therefore, we see in the previous question that Nick's youth group was

7 pipes fill a tank in 50 minutes. How many minutes does it take if there are 11 pipes?
Give your answer to the nearest minute.
Answer: With 11 pipes, you need 31.82 minutes to fill the tank.
Step-by-step explanation:
Let's define R as the rate at which one single pipe can fill a tank.
We know that 7 of them can fill a tank in 50 minutes, then we have the equation:
7*R*50min = 1 tank
Whit this equation, we can find the value of R:
R = 1 tank/(7*50min) = (1/350) tank/min.
Now that we know the value of R, we can do the same calculation but now with 11 pipes.
Then the time needed to fill the tank, T, is such that:
11*(1/350 tank/min)*T = 1 tank
We need to isolate T.
T = 1 tank/(11*(1/350 tank/min)) = 31.82 min
With 11 pipes, you need 31.82 minutes to fill the tank.
