Answer:
0.20 dollar per oz and Joshua brought 16 oz of strawberry
Step-by-step explanation:
1 lbs = 16 oz
3.20÷ 16
= 20 cent
20 cent per one ounce of strawberry
1 cent = 0.01 dollar
20 cent = 20 × 0.01
20 cents = 0.2 dollar
On a map of Arizona 2 inches represents 54 miles. The map distance from Yuma to Sentinel is 3 inches. What is the actual distance in miles between the cities?
Answer: 81 miles
Step-by-step explanation:
if 2 inches = 54miles then 1 inch is 27 miles because 54/2=27
so 3 inches means 3(27)=81 miles from yuma to sentinel

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.

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]
The CB radio of a trucker covers the circular area of (7,4). Find the equation of that circle. Give your answer in both standard and general form.
Answer:
Standard form is - (x - 7)² + (y - 4)² = 5²
General form is - x² + y² - 14x - 8y + 40 = 0
Step-by-step explanation:
Given - The CB radio of a trucker covers the circular area of (7,4).
Find the equation of that circle.
To find - Find the equation of that circle. Give your answer in both
standard and general form.
Proof -
Given that,
Center of CB radio = (7, 4)
Point on the Boundary = (10, 0)
Now,
We know that radius, r is
r = [tex]\sqrt{(7-10)^{2} + (4-0)^{2} }[/tex]
= [tex]\sqrt{(-3)^{2} + 4^{2} }[/tex]
= [tex]\sqrt{9 + 16}[/tex]
= [tex]\sqrt{25} = 5[/tex]
⇒r = 5
∴ we get
Standard form is - (x - 7)² + (y - 4)² = 5²
General form is -
x² + 7² - 2·7·x + y² + 4² - 2·4·y = 25
⇒x² + 49 - 14x + y² + 16 - 8y = 25
⇒x² + 65 - 14x + y² - 8y = 25
⇒x² + 65 - 14x + y² - 8y - 25 = 0
⇒x² - 14x + y² - 8y + 40 = 0
So, the general form is -
x² + y² - 14x - 8y + 40 = 0
A fruit seller brought 120 oranges for rs 500 and spent rs 60 for parking them into 10 boxes each containing a dozen oranges. If he sold a dozen of oranges for rs 58.8, find the profit percentage I know the answer it is 5% but I need the explanation for it in picture format it is also ok but in neat handwriting pls help
Answer:
First, we know that he spent rs500 plus rs60 in the whole process, then the total cost is:
C = rs500 + rs60 = rs560
Now he sells the oranges in packs of 12, then if he has 120 oranges, the total number of packs that he can sell is:
120/12 = 10
So he has 10 packs of 12 oranges.
And he sells each one for rs58.8
Then if he sells the 10 packs, the total revenue is:
R = 10*(rs58.8) = rs588
The profit is the difference between the revenue and the cost, here the profit is:
P = R - C = rs588 - rs560 = rs28
And the profit percentage is calculated as follows:
(P/C)*100%
Where P = profit and C = cost, then we have:
(rs28/rs560)*100% = 5%

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.

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.

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
