Answer:
Nickels; 5 cents
Dimes; 10 cents
Given that she has 30 nickels:
30(nickels) x 5(a single nickel) = $1.50
2.40 - 1.50 = $0.90, those 90 cents leftovers should then be divided by 10 cents because one dime contains 10 cents and you want to figure out how many dimes there are:
90/10 = there are 9 dimes
hello people ~
The length of a rectangular screen is 15 cm. Its area is 180 sq. cm. Find its width.
Answer:
W=12 cm.
Step-by-step explanation:
If the total area is 180 sq. cm., and you multiply length times width to find area, this time it is inversed. So you do 180/15=12
Answer:
12 cm
Step-by-step explanation:
The area of a rectangle = length × width
We know that the length is 15 cm and the area is 180 cm² so we can substitute this into the equation:
180 cm² = 15 cm × width
Finally, we can divide both sides by 15 to find the width:
width = 180 ÷ 15
width = 12 cm
Hope this helps!
Solve for s s/4 + 15 = 14
Answer: s = -4
Step-by-step explanation:
s/4 + 15 = 14
We can subtract 15 from both sides:
s/4 = -1
We can multiply both sides by 4:
s = -4

Step-by-step explanation:
1. Convert both mixed numbers into improper fractions:
2 2/3 → 8/3 (2 × 3 = 6 + 2 = 8/3)1 2/5 → 7/5 (1 × 5 = 5 + 2 = 7/5)2. Now we are doing 8/3 ÷ 7/5. We can use KCF to divide these fractions:
K = Keep the first fraction the sameF = Flip the second fractionC = Change the sign from × to ÷8/3 ÷ 7/5 → 8/3 × 5/7 = 40/21
3. Finally, convert 40/21 back into a mixed number: 1 19/21

What is the value of -4 (9 + 6)
Explain how you got it
Check the picture below.
so, the figure is really one big square, a 10x10, with four triangles in it, now, if we just get the area of the square, well 10x10 is just 100 in², and then get the areas of those three triangles, the yellow, purple and orange ones, and subtract their area from that of the larger square, what's leftover is the shaded triangle. By subtracting the areas from the larger area, we're in essence making a big hole in the larger area, and what's leftover is what was never subtracted.

Reflect triangle A in the line y=1
Answer:
To reflect the shape in the line y = 1:
The x-coordinates will stay the same.The y-coordinate = 1 - (y-value - 1)(-4, 4) → (-4, -2)
(-1, 4) → (-1, -2)
(-1, 2) → (-1, 0)
Henry is playing a game using a bag of tokens that contains exactly 28 black tokens and 12 white tokens. On each player’s turn a single token is drawn at random from the bag and then returned to the bag at the end of the turn. Each token is the same size and shape. Henry recorded the first 10 draws as either black (B) or white (W) as shown below.
B, W, W, W, B, B, B, W, B, B
Part B: Based on the information given, what is the experimental probability of the next player drawing a white token? Explain
Using it's concept, it is found that there is a 0.4 = 40% experimental probability of the next player drawing a white token.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In an experimental probability, these number of outcomes are taken from previous trials.
In this problem, in the first 10 draws, 4 resulted in the player drawing a white token, hence:
p = 4/10 = 0.4.
There is a 0.4 = 40% experimental probability of the next player drawing a white token.

what is the value of x in the diagram below?
Answer:
C
Step-by-step explanation:
using the Altitude- on- Hypotenuse theorem
(leg of big Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse )
x² = 20 × (20 + 36) = 20 × 56 = 1120 ( take square root of both sides )
x = [tex]\sqrt{1120}[/tex] = [tex]\sqrt{16(70)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{70}[/tex] = 4[tex]\sqrt{70}[/tex]

a rectangular prism is 18 inches long 6 1/2 inches wide and has a volume of 292 1/2 cubic inches. which equation can u use to find the height
The equation that represent the height of the rectangular prism is h = v / lw, where the value of height is 2.5 inches
Volume of a rectangular prismv = lwhwhere
l = length
w = width
h = height
Therefore,
l = 18 inches
w = 6 1 / 2 = 13 / 2 inches
h =?
v = 292 1 / 2 = 585 / 2
Therefore,
h = v / lw
h = 585 / 2 × 1 / 18 × 2 / 13
h = 585 / 234
h = 2.5 inches

$15+$2.70=$17.70
Answer:
Tip: $2.70
Total: $17.70

Solve the simultaneous equations
3x + y = 25
2x – y = 10
Answer:
x=7 and y=4
Step-by-step explanation:
I will use the elimination method:
Since the co-efficient of both y's are the same number but different signs we add the 2 equations to eliminate the y:
3x + y =25
+ + +
2x - y = 10
Simplify:
5x=35
Divide both sides by 5:
5x÷5=35÷5
Simplify:
x=7
Substitute this into either equation 1 or 2 ( I chose 1):
3(7) + y = 25
21 + y = 25
Subtract 21 from both sides and simplify to get y:
21+y-21=25-21
y=4
Therefore x=7 and y=4
