To make 3 litres of pale purple paint you mix:
1.5 litres red
1.25 litres of blue
0.25 litres of white paint.
a How much red paint is needed to make 8 litres of paint?
Answers
Answer:
We need 4 litres of red paint.
Step-by-step explanation:
We need to take their respective precentages to compare the 3 litres of paint to 8 litres of paint.
[tex] \frac{1.5}{3} \times 100\% = 50\% \\ \frac{1.25}{3} \times 100\% = 41.67\% \\ \frac{0.25}{3} \times 100\% = 8.33\% \\ [/tex]
Now, we know that the pale purple paint contains 50% red paint, 41.67% blue paint, and 8.33% white paint.
Now, we will transfer these percentages to the 8 litres of paint:
[tex]50\% \: of \: 8 \: litres = 0.5(8) = 4 \: litres \\ 41.67\% \: of \: 8 \: litres = 0.4167(8) = 3.3336 \: litres \\ 8.33\% \: of \: 8 \: litres = 0.0833(8) = 0.6664 \: litres[/tex]

Solve for x: 2/5=4/x
Answers
Explanation: First you cross-multiply to get 2x=20 and then divide by 2 to get x=10
9514 1404 393
Answer:
x = 10
Step-by-step explanation:
Using your number sense, you recognize that a fraction equivalent to 2/5 that has 4 in the numerator is 4/10. This tells you x = 10.
__
The usual instructions for solving this algebraically are to "cross multiply", then divide by the coefficient of x.
2/5 = 4/x . . . . given
2x = 20 . . . . . multiply by 5x on both sides
x = 10 . . . . . . . divide by 2
__
You can do the above two steps both at once: multiply by 5/2x.
(2/5)(5/2x) = (4/x)(5/2x)
x = 20/2 = 10
Arya deals in clothing and accessories. She bought 10 shirts at a wholesale price of 1120 each and sold them
all at a profit of 40 percent.
What was the price Arya charged for the 10 shirts?
Answers
Answer:
15680
Step-by-step explanation:
Cost of 1 shirt: 1120
Cost of 10 shirts: 11200
Add 40% to the cost of 10 shirts:
40% + 100% = 140% = 1.4
1.4 * $11200 = 15680
Answer: 15680

If the shortest side of a right triangle is 19, what are the lengths of the other TWO sides
that makes the side lengths a Pythagorean triple? HELP ASAP PLZ
Answers
Answer:
180 and 181
Step-by-step explanation:
A pythagorean triple basically refers to numbers that satisfies the pythagorean theorem. This theorem states that the square of the hypotenus (a) of a right angle triangle is equal to the sum of the squares of the other two sides (b and c).
That is;
a² = b² + c²
If the shortest side is 19, the other two sides are 180 and 181.
The hypotenus is the longest side of the right angle triangle.
Check:
181 = 180 + 19
181² = 180² + 19²
32761 = 32400 + 361
32761 = 32761

Trisha has $100 to spend on presents for 4 of her friends. She wants to spend the same amount on each friend. How much money can she spend on each friend (x)?
*Choose the inequality that best matches this scenario.
a. 4+x ≤ 100
b. 4x ≤ 100
c. x ÷ 100 ≥ 4
d. 100 - x ≥ 4
Answers
Answer:
B
Step-by-step explanation:
Trisha has $100. So she has to spend less than $100 or exactly 100 on her friends. The sign to represent this is ≤ ( the less than or equal to sign )
so if she has 4 friends and wants to spend x on each friend, she would spend a total of 4x on her 4 friends.
Remember that she has to spend less than or equal to $100. The equation to represent this is 4x ≤ 100
graph the equation y= -3x+4
