Bella has 7 more dimes than nickels, for a total value of $1.45. If n represents the number of nickels, what equation could be used to find the number of nickels Bella has?
Answers
Answer:
15 nickels
Step-by-step explanation:
so you know she has 7 dimes so youre starting off at .70
how much money would it take to get from .70 to 1.45?
.75 cents to get from .70 to 1.45 which is 15 nickels
Answer:
0.15n + 0.70 = 1.45
5 nickels
Step-by-step explanation:
Nickel = 5 cents = $0.05
Dime = 10 cents = $0.10
Let n = number of nickels
Let d = number of dimes
Given:
Bella has 7 more dimes than nickelsTotal value of $1.45Equation 1: 0.05n + 0.10d = 1.45
Equation 2: d = n + 7
Substitute Equation 2 into Equation 1 and solve for n:
⇒ 0.05n + 0.10(n + 7) = 1.45
⇒ 0.05n + 0.10n + 0.70 = 1.45
⇒ 0.15n + 0.70 = 1.45
⇒ 0.15n = 0.75
⇒ n = 5
Therefore, Bella had 5 nickels and 12 dimes.

Name Guided Practice DO Do You Understand? 1. If the orchard has 200 seedlings and 12 are planted in each row, how many rows will be filled? Draw place-value blocks to show your answer. In Problem 1. what does the remainder I don't get how 200 is 16
Answers
Answer:
16 rows, 8 seedlings left.
Step-by-step explanation:
Divide 200 by 12, since 200 seedlings are going to be split in 12 groups in order to fill the rows.
200 ÷ 12 = 16 with a remainder of 8.
The remainder is basically what is left.
Since 12 seedlings are planted in each row, 8 seedlings is not enough to completely fill the row. So, the answer is 16 rows with 8 seedlings left.

The graph of the function is of the form
f(x) = a * sin(kc – c) + h.
Answers
Explain
There 0,3 on the graph
You use this formula
f(x)=asin(kx-c)+h
and the maximum and minimum value of this function
a+ h and -a+ h
So a=3 and h=0
So we have
We have; f(x)= 3sin(kx - c)
and we have from the graph;
f(O)=3
So
Sin(-c) =-1
Therefore C=. Pi/ 2 +2pi n
We have period of the function is pi

factorise : 3x² + 10x + 8
Answers
Answer:
(x + 2)(3x + 4)
Step-by-step explanation:
3x² + 10x + 8
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × 8 = 24 and sum = + 10
the factors are + 6 and + 4
use these factors to split the x- term
3x² + 6x + 4x + 8 ( factor first/second and third/fourth terms )
= 3x(x + 2) + 4(x + 2) ← factor out (x + 2) from each term
= (x + 2)(3x + 4) ← in factored form

James buys 7 baseballs and 1 bat.
• Each baseball costs the same amount.
• The bat costs $42.00.
• The total cost is $66.50, before tax.
What is the cost of each baseball?
$3.50
$6.00
$9.50
$15.50
Answers
24.50 / 7 = 3.50
The cost of each baseball is $3.50, option A is correct.
Given that the Number of baseballs are 7.
Cost of the bat = $42.00
Total cost before tax = $66.50
The total cost of the baseballs can be calculated by multiplying the cost of each baseball by the number of baseballs:
Total cost of baseballs = 7 × x
The total cost of all items, including the baseballs and the bat, is the sum of the individual costs:
Total cost = Total cost of baseballs + Cost of the bat
$66.50 = 7x + $42.00
We need to solve this equation for x.
Subtracting $42.00 from both sides:
$66.50 - $42.00 = 7x
$24.50 = 7x
Dividing both sides by 7:
$24.50 / 7 = x
x = $3.50

The prism below has dimensions 2 inches by 3 inches by 4 inches. To the right of the prism, shade the number of prisms necessary, if stacked on top of each other as shown, to create a new prism with a surface area between 100 square inches and 130 square inches.
HELPPPPPPPPPPPP
Answers
The area of the stacked prism is the amount of space on it
To create a total area between 100 square inches and 130 square inches, 2 to 2.5 prisms
How to determine the number of prisms?
The dimension of the prism is given as:
2 inches by 3 inches by 4 inches
The surface area of the prism is calculated as:
A = 2 * (LW + WH + LH)
This gives
A = 2 * (2 * 3 + 3 * 4 + 2 * 4)
Evaluate the product
A = 52
When the prisims are stacked onto one another, the surface area is between 100 square inches and 130 square inches.
So, the number of prisms (n) needed is:
100/ 52 < n < 130/52
Evaluate the quotient
1.9 < n < 2.5
Approximate
2 < n < 2.5
Hence, 2 to 2.5 prisms are needed to create a total area between 100 square inches and 130 square inches.
