Last year, students planted 8 tomato plants and 16 pepper plants in a school
garden. This year, the students planted 15 tomato plants. They want to have the
same ratio of tomato plants to pepper plants as last year. Pepper plants cost
$4.33 each. What is the cost, in dollars, of the pepper plants for this year's garden
From the ratio gotten, the total cost of the pepper will be $129.90.
How to solve a ratioSince the students planted 8 tomato plants and 16 pepper plants in a school garden. The ratio will be:
= 8/16 = 1:2
This year, the students planted 15 tomato plants, the number of pepper will be:
= 15 × 2 = 30
Since pepper plants cost $4.33 each, the total cost will be:
= 30 × $4.33
= $129.90

Answer:
This alot but ill help you with 2 of them to learn em
Step-by-step explanation:
1) 2x^2 +5 =167
Subtract the 5 from both sides to get the equation 2x² = 162
Then divide the 2 from both sides to get x² = 81, Then square root from both sides to get x= 9
6) 2(2y +4)²=72
Divide 2 from both sides to get (2y+4)²=36
Then square root that to get 2y+4 = 6
subtract 4 from both sides to get 2y =2
Then divide both sides from 2. Y=2

Draw a horizontal line at the end of the 8 meter horizontal line.
Find the area of the horizontal rectangle
L = 8 + 3
W = 2
Area = L*w
Area = 11*2
area = 22 m^2
Now do the vertical rectangle
L = 8
w = 3
Area = L*w
Area = 8 * 3
Area = 24 m^2
Total Area = 24 + 22 = 46 m^2

Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 10 gallons of fuel, the airplane weighs 2064 pounds. When carrying 45 gallons of fuel, it weighs 2288 pounds. How much does the airplane weigh if it is carrying 60 gallons of fuel?
Answer:
Now, to answer the question, we need to add the weight of (58-42) = 16 gallons of fuel to the weight of the plane
carrying 42 gallons of fuel, 2331 pounds.
So, the answer is 2331 + 16*5.5 = 2419 pounds.

joe has a handful of dimes and quarters that values to $5.30. He has one fewer than twice as many dimes than quarters. How many of each coin does he have?
Answer:
12 quarters 23 dimes
Step-by-step explanation:
x(0.25)+(2x-1)(0.10)=5.30
0.25x+0.2x-0.10=5.30
0.45x=5.40
x=12
12 quarters
12(2)=24-1=23 dimes
Joe has 12 quarters coins and 23 dimes coins .
What is equation ?Equation is a combination of mathematical variables, in which two mathematical expressions are equal.
Let the number of quarters be n,
Therefore the number of dimes will be 2n-1.
Given that,
The total value of dimes and quarters is $5.30.
Write above text in equation form.
(0.25)n+(0.10)(2n-1)=5.30
0.25n+0.20n-0.10=5.30
.45n=5.40
n=12
And 2n-1=23
Means Joe has 12 quarters coin and 23 dimes coins .

Find the probability that a student earns a
grade of A, B, or C.
p = [?]
Enter a decimal rounded to the nearest hundredth.
Answer:
0.714
Step-by-step explanation:
P(A or B or C) = P(A) + P(B) + P(C)
=(5/35)+(10/35)+(15/35)
=25/35
=0.714
Probability that a student earns a grade of A, B, or C is equals to 0.86.
What is probability?
" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Given,
Total number of students = 35
Number of students getting grade A = 5
Number of students getting grade B = 10
Number of students getting grade C = 15
Substitute the value in the formula of probability we get,
P(A or B or C) = P(A) + P(B) + P(C)
= [tex]\frac{5}{35} +\frac{10}{35} +\frac{15}{35}[/tex]
= [tex]\frac{30}{35}[/tex]
= 0.8571
= 0.86 (decimal rounded to the nearest hundredth)
Hence, probability that a student earns a grade of A, B, or C is equals to 0.86.

Jennifer's school is selling tickets to a chorus concert. On the first day of ticket
sales, the school sold 3 senior citizen tickets and 1 child ticket for a total of $38.
On the second day of ticket sales, the school sold another 3 senior citizen tickets
and 2 child tickets for $52.
Answer:
senior: $8child: $14Step-by-step explanation:
The given price relations allow us to write two equations involving the prices of the tickets. Those can be solved to find ticket prices.
Let s and c represent the prices of senior and child tickets respectively. Then the described sales can be written as ...
3s +c = 38 . . . . first day's sales
3s +2c = 52 . . . second day's sales
__
Subtracting the first equation from the second eliminates the s variable and gives the price of a child ticket:
(3s +2c) -(3s +c) = (52) -(38)
c = 14 . . . . . simplify
Then the price of a senior citizen ticket can be found using the first equation:
3s +14 = 38 . . . . . substitute for c
3s = 24 . . . . . . . subtract 14
s = 8 . . . . . . . divide by 3
The price of a senior citizen ticket is $8; the price of a child ticket is $14.
