Sra bought a pair of shoes that were on sale for 30 percent off. If the oringal prices was 29 what is the sale price on the shoes?
Answer:
$20.30
Step-by-step explanation:
Original price = 100% of the price
100% = $29
1% = 29 ÷ 100 = 0.29
Sale percentage = 30%
30% = 0.29 x 30 = 8.70
Since they are asking for the sale price of the shoes, it means the price of the shoes after the discount of the sale percentage.
29 - 8.70 = 20.3

82% of what number is 492?
answer
600
Step-by-step explanation:
Step 1: If 82% of a number is 492, then what is 100% of that number? Setup the equation.
492/82%=Y/100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
82Y = 492 x 100
82Y = 49200
Y=49200100=600

hope this helped!Find the distance d between 21 = (-7 - 6i) and Z2 = (-15 – 12i). Express your answer in exact terms and simplify, if needed.
Answer:
10
Step-by-step explanation:
The distance is equal to the modulus of Z1-Z2.
[tex]Z_1 - Z_2 = -7 - 6i - (-15 - 12i) = 8 + 6i\\|8 + 6i| = \sqrt{8^2 + 6^2} = \sqrt{64 + 36} = \sqrt{100} = 10[/tex]

Find the solution set of the inequality
8x−8≤−72.
Answer:
x≤-8
Step-by-step explanation:
When solving 8x-8≤-72, first add 8 to both sides of the inequality.
This leaves you with 8x≤-64.
Divide both sides by 8: 8x/8 and -64/8
This leaves you with x≤-8 as your solution.
If the determinant of this matrix is 24, what is the value of b? A. 4 B. 8 C. 16 D. 20
Answer: B=8
Step-by-step explanation: I got this right on Edmentum.
The value of the variable b will be 8. Then the correct option is B.
What is determinant?The determinant in math is a scalar quantity that is a result of the rows and columns of a matrix form.
If the determinant of this matrix is 24.
The matrix is given below.
[tex]\begin{bmatrix}-5 & 4 & 1 \\5 & -7 & -4 \\-6 & b & 6 \\\end{bmatrix}[/tex]
R₁ ⇒ R₁ + R₂
[tex]\begin{bmatrix}0 & -3 & -3 \\5 & -7 & -4 \\-6 & b & 6 \\\end{bmatrix}[/tex]
C₂ ⇒ C₂ – C₃
[tex]\begin{bmatrix}0 & 0 & -3 \\5 & -3 & -4 \\-6 & b-6 & 6 \\\end{bmatrix}[/tex]
Then the value of b will be
–3[5(b – 6) – (–3)(–6)] = 24
(5b – 30 – 18) = –8
5b = 40
b = 8
Then the correct option is B.

Step-by-step explanation:

have a great day!!!
If two ratios are similar we called the ratios to be in proportion.
The length of side x is 6 cm.
What is proportion?If two ratios are similar we called the ratios to be in proportion
We have,
Two shapes:
Consider the bigger shape width = 15 cm and length = 10 cm.
Consider the smaller shape width = 9 cm and length = x cm.
Let the ratio of bigger shape:
= Width / length
= 15/10
Let the ratio of smaller shape:
= Width / length
= 9/x
If the two figures are mathematically similar we can say that the two figures are in proportion.
We can write it as:
15/10 = 9/x
3/2 = 9/x
x = 6
Thus the length of side x is 6 cm.

4) A dozen cookies cost $18.75. Twenty cookies cost $25.50. Which has the lower unit price?
ROUND YOUR ANSWER TO THE NEAREST HUNDREDTHS. *
Answer:
Twenty cookies deal
Step-by-step explanation:
A dozen cookies cost 18.75. A dozen is exactly 12. If you divide 18.75 by 12 you should get the unit price which is about $1.56 for each cookie. For 25.50 you just divide it by 20 and you should get about 1.20 which makes it a better deal.
