A newspaper carrier has $4.40 in change. He has six more quarters than dimes but three times as many nickels as quarters. How many coins of each type does he have?
Answer:
10 quarters, 4 dimes and 30 nickelsStep-by-step explanation:
Given:
Quarter = 25c, their number is qDime = 10c, their number is dNickel = 5c, their number is nTotal amount = $4.40 = 440 cEquations:

Answer:
x ≈ 33.0
Step-by-step explanation:
The third angle in the triangle is
180° - 70° - 76° = 180° - 146° = 34°
Using the Sine rule in the triangle
[tex]\frac{x}{sin76}[/tex] = [tex]\frac{19}{sin34}[/tex] ( cross- multiply )
x × sin34° = 19 × sin76° ( divide both sides by sin34° )
x = [tex]\frac{19sin76}{sin34}[/tex] ≈ 33.0 ( to the nearest tenth )
Answer:
x=33 (since it says to round it)
Step-by-step explanation:
This is an ASA triangle.
First, we need to find the value of the unlabeled angle, which is simple:
180°-70°-76°=34° Lets call that angle A
Now we use the law of sines:
x/sinX = a/sinA
x/sin76° = 19/sin34°
Then:
x = (19/sin34°) × sin76°
x = 32.968

Answer:
[tex]\large\boxed{\boxed{\underline{\underline{\maltese{\pink{\pmb{\sf{\: Solution :- \: 11:30 \: p.m }}}}}}}}[/tex]
Step-by-step explanation:
The given question is to find 2 hours before 1:30 a.m.
The a.m or 'ante meridiem' & p.m or 'post meridiem'. is used in the 12 hour clock system which is a system where the 24-hours in a day is divided into 2 equal parts → a.m & p.m.
The time after 12 midnight till 12 noon is included in a.m. while the time from 12 noon to 12 midnight is included in p.m.
So, 2 hours before 1:30 a.m,
1:30 a.m - 2:00 = 11:30 p.m.This happened because, it's under the 12-hour system so, the numbers range from 1 - 12 . Since, 1:30 a.m comes somewhat towards the beginning, we have to go back 2 hours & that's 11:30 p.m.

Which solution correctly solves the problem 5x - 16 = 79?
Answer and Step-by-step explanation:
Alright, so we have the problem 5x-16=79. First, we need to add 16 to both sides of the equation to cancel out the 16 like this:
5x - 16 = 79
+ 16 + 16
5x = 95
Now we need to divide the 5 into the 5x to cancel out the 5. This will leave us with the variable left over like this:
x = 95
5
Five can be divided into 95, so 95 divided by 5 = 19. So the answer is:
x = 19
I hope this helps.
The solution to the given equation is 19.
The given equation is 5x-16=79.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

A landscaper wants to increase the size of one of his square gardens. The garden measures 8 feet on each side. The landscaper
plans to increase each side of the garden to be 175% of its current measure.
How many square feet larger is the area of the new garden than the area of the current garden?
A. 260ft
B.160ft
C.132ft
D.48
Answer:
its c
Step-by-step explanation:
The area of the new garden will be 132ft longer than that of the current garden
Area of the squareThe formula for calculating the area of a square is expressed as:
A = L²
If the garden measures 8 feet on each side, then;
A = 8²
A = 64ft²
If the side length is increased by 175%, hence new length will be;
l = 8 + (1.75*8)
A = 14 * 14ft
A = 196 ft²
Difference = 196 - 64
Difference = 132ft
Hence the area of the new garden will be 132ft longer than that of the current garden

What percent of 56 is 21?
A: 3/8%
B: 3 3/4%
C: 37 1/2%
D:375%
Answer:
[tex]37\frac{1}{2}[/tex]
Step-by-step explanation:
let x be the percent
Now we have
x% of 56=21
x/100=21/56
x=100x21/56
x=[tex]31\frac{1}{2}[/tex]%
The percent of 56 that is equal to 21 is 37 1/2% by setting up a proportion and solving the equation. This means that 37 1/2% of 56 is equal to 21.
To find the percentage, we can set up a proportion. Let x represent the unknown percentage:
x/100 = 21/56
To solve for x, cross-multiply:
56x = 100 * 21
56x = 2100
Divide both sides of the equation by 56 to isolate x:
x = 2100/56
Simplifying the fraction, we get:
x = 37 1/2%
Therefore, the answer is option C: 37 1/2%.
To find the percentage of 56 that is equal to 21, we can set up a proportion between the unknown percentage and the given values. The proportion is x/100 = 21/56. Cross-multiplying and solving the equation yields x = 37 1/2%. This means that 37 1/2% of 56 is equal to 21.

Let n be the middle number of three consecutive Integers. Write an expression for the sum of these Integers.
Consecutive integers are those that occur one after the other. Let's use 2, 3, 4 as an example.
The middle number is 3 (n). To get to 2 from 3, we need to subtract 1 (n - 1). To get to 4 from 3, we need to add 1 (n + 1).
Now that we understand how to get to each number from the middle number, we can create our expression.
(n - 1) + n + (n + 1)
(n + n + n) + (1 - 1)

Slope = 2; (14, 33)
Answer:
y = 2x + 5
Step-by-step explanation:
Consider the format of a line equation, y = mx + b
The slope is represented as the variable 'm.'
Since we already know that the slope is 2, we can input it into the format.
y = 2x + b
Assuming that the point (14, 33) is a point of intersection, we can input these numbers into the equation in order to find the value of b, or the y-intersect.
33 = 2(14) + b
33 = 28 + b
5 = b
