Answer:
.25q+.10d=25.10
q+d=128
Step-by-step explanation:
Since a quarter is 25 cents and a dime is 10 cents that is how you figure out your first equation. You set it equal to 25.10 because that is the amount of money it totals to. The second equation (q+d=128) is used because the amount of quarters plus dimes needs to make 128.
Find the constant of proportionality for the table of values and write in the form y = kx
A) y = 1/4x
B) y = 4x
C) y = 6x
D) y = 24x
Answer:
Option 'B' is correct.
Step-by-step explanation:
Since we have given that
Number of lemons used is denoted by 'y'.
Number of glasses of lemonade is denoted by 'x'.
As we can observe that ,
[tex]\frac{6}{24} = \frac{8}{32} = \frac{7}{28} = \frac{2}{8} = \frac{4}{16} = \frac{1}{4} \\[/tex]
so we can write i as
[tex]\frac{x}{y} = \frac{1}{4}[/tex]
By cross multiplication
y=4x
So, if write it in the form y=kx,
It will be y=4x.

In the inequality -9 ≤ 9, which number appears farther left on a number line and why?
A~ 9 appears farther left because 9 is smaller than -9
B~ -9 appears farther left because -9 is smaller than 9
C~ -9 appears farther left because -9 is larger than 9
D~ 9 appears farther left because 9 is larger than -9
Answer: B
because of the reason given. (smaller numbers are father left and larger numbers are father right on the number line).
Answer: A is the answer
Step-by-step explanation: since -9 is a negative is and 9 is positive, -9 will appear furthest to the left on a number line.
49. Calculate the value of c in the triangle below.
Answer:
26 cm
Step-by-step explanation:
c = a^2 + b^2 = 10^2 + 24^2 = 26
Answer:
26m.
Step-by-step explanation:
since the triangle has a 90° angle, it means that the triangle is a Right - angled triangle. So, we are going to use the pathagorean theorem to find the missing side.
a² + b² = c²
a and b are the two shorter and adjacent sides to the 90° angle
c is the hypotenuse
10² + 24² = c²
100 + 576 = c²
676 = c²
find the square root of 676 to get c = 26.

A sign says that the price on all music equipment is 30% off the original price. you buy an electric guitar for the sale price of $315.
A-what is the original price?
B-How much money did you save off of the original price?
C-What percent of the original price is the sale price?
Answer:
Step-by-step explanation:
sale price = original price minus discount.
discount = original price * discount percent / 100.
let s represent the sale price.
let p represent the original price.
let d represent the discount.
let k represent the discount percent.
the above formulas become:
s = p - d
d = p * k/100
we know that s = 315.
we know that k = 30.
formulas become:
315 = p - d
d = p * 30/100
simplify these formulas to get:
315 = p - d
d = .3p

There is approximately 0.62 km in 1 mile. If you walk 12.5 miles, how many kilometers did you walk?
Answer:
Approximately 8.125 km
Step-by-step explanation:
The ratio 0.62 : 1 is equal to the ratio 8.125 : 12.5
To get this answer
Multiply both sides of the ratio by 12.5. 0.62(×12.5) : 1(×12.5)Your answer will be 8.125 : 12.5The final answer would be 8.125 km : 12.5 miles.1.What are the 3 central beliefs of Christianity

How is unit rate related to the linear equation?
Answer:
https://www.khanacademy.org/math/cc-eighth-grade-math/cc-8th-linear-equations-functions/cc-8th-graphing-prop-rel/v/graphing-proportional-relationships-example
Step-by-step explanation:
Answer:
A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled. Because of this, it is also called a direct variation. The equations of such relationships are always in the form y = mx , and when graphed produce a line that passes through the origin. In this equation, m is the slope of the line, and it is also called the unit rate, the rate of change, or the constant of proportionality of the function.
I WILL GIVE BRAINLIEST!
(Picture provided)
What is m
A. 56°
B. 68°
C. 112°
D. 124°
Answer:
I couldn't tell which angle you meant, so the two missing angles are Q = 56 and S = 68
Step-by-step explanation:
Q = 180 - 124
Q = 56
56 (angle Q) + 56 (angle R) = 112
S = 180 - 112
S = 68

Find the missing angle.
Answer:
45°
Step-by-step explanation:
All angles in a triangle add up to 180°
180 - (90 + 45)
= 180 - 135
= 45
Therefore the missing angle is 45°
Answer: answer is 45
Step-by-step explanation:
I added 90 with 45, got 135, then subtracted 180 with 135...

How can the addition porperty of equality be used to solve substraction equations? (Please answer correctly)(no links)
Answer:
just as you can add the same value to each side of an equation without changing the meaning of the equation, you can subtract the same value from each side of an equation.
by-step explanation:
x+7=42
Since 7 is being added to the variable, subtract 7 to isolate the variable.
To keep the equation balanced, subtract 7 from both sides of the equation.
x+7=42
-7 over x+0
-7 over 35
so answer is 35
8. Find the surface area of a triangular pyramid if the area of each phase is 16 cm² and each of its lateral faces has an area of 9 cm².
Answer:
The base of a right pyramid is an equilateral triangle with area 16√3 cm². area of one of its lateral faces is 30 cm²
To find : height (in cm) i
Solution:
The base of a right pyramid is an equilateral triangle with area 16√3 cm²
Area of an equilateral triangle = (√3 / 4) Side ²
(√3 / 4) Side ² = 16√3
=> Side ² = 64
=> Side = 8 cm
Distance of center of triangle to mid point of Side for Equilateral triangle = side/ 2√3 = 8/ 2√3 = 4/√3
Let say Height = H
Slant Height = √((4/√3)² + H²)
Area of lateral surface = (1/2) * base * Slat Height
= (1/2) * 8 * Slant height = 30
=> Slant height = 15/2
15/2 = √((4/√3)² + H²)
=> 225/4 = 16/3 + H²
=> 611/12 = H²
=> H = 7.135 cm
