1. In some music, a whole note equals one measure, a quarter note
equals , of one measure, and an eighth note equals of one
measure. If one measure has two quarter notes and an eighth note,
what notes can make up the rest of the measure? Write and solve an
equation.
Answer:
3 eighths are needes to make up the rest of the measure.
Step-by-step explanation:
1/4 + 1/4 + 1/ 8 + x = 1
2/4 + 1/8+x=1
4/8 + 1/8+x=1
5/8 + x=1
x=1 - 5/8
x=3/8
We need three eights.(Because 3/8=1/8+1/8+1/8 and 1/8 represents an eights)

Answer:
1. -4/7
2. 4/3
3. x^2 + 16x + 63
4. x^2 + 19x + 90
Step-by-step explanation:
1. (1, 8) and (8, 4)
slope = m = (8 - 4)/(1 - 8) = -4/7
2. (2, 4) and (5, 8)
slope = m = (8 - 4)/(5 - 2) = 4/3
3. (x + 9)(x + 7) =
= x^2 + 7x + 9x + 63
= x^2 + 16x + 63
4. (x + 10)(x + 9) =
= x^2 + 9x + 10x + 90
= x^2 + 19x + 90
Three times the sum of d and r square.
Answer:
3*(d + r^2)
Step-by-step explanation:
Sometimes you read what is needed from front to back and other times it goes from back to front. This is one of those things that goes from back to front.
d and r^2 = d + r^2 In this case and means plus.
Now you deal with the three.
3(d + r^2) which creates the distributive property.
Answer:
3*(d + r^2) is correct answer
Step-by-step explanation:

It took Emma 3/4 hour to rake the leaves. It took her 1/5 hour more to
weed the garden than it took to rake the leaves. It took her 0.2 hour
more to mow the lawn than it took to weed the garden. Discuss a
strategy you can use to find the answer. Then determine how long it
took her to do all three chores.
9514 1404 393
Answer:
total: 2.85 hours = 2 17/20 hours
Step-by-step explanation:
Strategy: convert all fractions to decimals, determine weeding and mowing times, and add the three times to find the total.
3/4 = 0.75
1/5 = 0.2
Solution:
raking time: 0.75 hours
weeding time: 0.75 +0.2 = 0.95 hours
mowing time: 0.95 +0.2 = 1.15 hours
__
Total time: 0.75 +0.95 +1.15 = 2.85 hours = 2 17/20 hours
_____
Additional comment
You may recognize that 0.95 is the middle of three equally-spaced values. Then the total will be 3×0.95 = 2.85 hours.

For what values of k will the equation 4x² + 8x + k = 0 have two real solutions?
Answer:
k < 4
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant Δ = b² - 4ac informs us about the nature of the solutions.
• If b² - 4ac > 0 then 2 real and distinct solutions
• If b² - 4ac = 0 then 1 real and repeated solution
• If b² - 4ac < 0 then no real solutions
4x² + 8x + k = 0 ← is in standard form
with a = 4, b = 8 , c = k , then
b² - 4ac = 8² - (4 × 4 × k) = 64 - 16k
For two real solutions
64 - 16k > 0 ( subtract 64 from both sides )
- 16k > - 64
Divide both sides by - 16, reversing the symbol as a result of dividing by a negative quantity.
k < 4
Then any value less than 4 will ensure the equation has two real solutions

Hello I need help in my math
12: {x,y,z} ? {a,b,c} is it equal or not?
13: {0} ? { } equal or not?
Please help no spam no links I need help mark brainliest!!
12: Equal, because the cardinal number of {x,y,z} are same as {a,b,c}, that is, 3.
13: Not equal, because in set {0}, there is one element , while in set { } , there are no elements at all .
Hope it helps you. Have a nice day!

Nora has a flower arrangement with 7 pink flowers, 9 purple
flowers, and 5 white flowers. Which sentence is not true?
The ratio of total flowers to pink flowers is 21: 7
The ratio of white
flowers to purple flowers is 5:9.
The ratio of purple flowers to total flowers is 16 to 21.
Answer:
The ratio of purple flowers to total flowers is 16 to 21 is NOT TRUE because your total is already 21 so it would make no sense for 16 to be in the ratio

2. List all of the the subsets of {a,b,c}
3. How many subsets are there of {a,b,c,d,e,f}
Answer:
Step-by-step explanation:
1. If A is a subset of B and B is a subset of A then A and B must be equal.
2. The subsets of {a,b,c} are
{ } (emptyset}, {a}, {b}, {c}, {a,b}, {a,c}, {b,c}, {a,b,c}

Solve the equation.
Give your simplified answer as an improper fraction.
7(x + 1) = 1 – 2(5 – x)
? ]
W
Answer:
-16/5
Step-by-step explanation:
7(x+1)=1-2(5-x)
7x+7=1-10+2x
7x-2x=1-10-7
5x = -16
x = -16/5
Answer: [tex]\huge {x = -\frac{16}{5} }[/tex]
Step-by-step explanation:
Given equation
7 (x + 1) = 1 - 2 (5 - x)
Expand parentheses and apply the distributive property
7x + 7 = 1 - 10 + 2x
Combine like terms
7x + 7 = -9 + 2x
Subtract 2x on both sides
7x + 7 - 2x = -9 + 2x - 2x
5x + 7 = -9
Subtract 7 on both sides
5x + 7 - 7 = -9 - 7
5x = -16
Divide 5 on both sides
5x / 5 = -16 / 5
[tex]\boxed{x=-\frac{16}{5} }[/tex]
Hope this helps!! :)
