convert 62 feet per second to (5280 = 1 mile)
Answer:
Step-by-step explanation:
if you want to convert to miles per hour, then
in 1 second distance covered=62 ft
In 60 seconds (1 minute) distance covered=62×60=3720 ft.
In 60 minutes (1 hour) distance covered=3720×60 ft=223200 ft
=223200/3=74400 yards
=74400/1760=7440/176=930/22=465/11 miles=42 3/11 miles
62 ft per second=42 3/11 miles per hour.

Answer:
3.4
Step-by-step explanation:
both angles are equal, i.e 16x - 9 = 45.
the value of x is 3.375
Answer:
The value of x is 9.
Step-by-step explanation:
i used the equation (16x-9) + 45 = 180
1. i added -9 +45 i got 36
2. 16x + 36 = 180
3. i subtract 36 from 36 and 180
4. 16x=144
5. i divide 16 from 16x and 144
6. x=9

The number of dogs Corey can wash varies directly with the amount of time he spends washing dogs. Corey can wash 12 dogs in 2 hours.
How many dogs can Corey wash in 8 hours?
Enter your answer in the box.
dogs
Answer:
corey can wash 48 dogs in 8 hours
Step-by-step explanation:
we know that he can wash 12 dogs in 2 hours. we need to know how many dogs he can wash in 1 hour, to do that we take the 12 dogs divided by 2 hours
12/2 = 6 dogs
he can wash 6 dogs in 1 hour
to find out how many dogs he can was in 8 hours you take number of dogs per hour times amount of time given.
6dogs * 8 hours= 48 dogs

A fish market bought two swordfish at a rate of $12 per pound. The cost of the larger fish was three times as great as the cost of the smaller fish. The total cost of the two fish was threes A fish market bought two swordfish at a rate of $12 per pound. The cost of the larger fish was three times as great as the cost of the smaller fish. The total cost of the two fish was $3696. What's the answer
Answer:
The larger fish weigh 231 pounds and the smaller fish weigh 77 pounds
Step-by-step explanation:
Here is the complete and correct question:
A fish market bought two swordfish at a rate of $12 per pound. The cost of the larger fish was three times as great as the cost of the smaller fish. The total cost of the two fish was $3,696. How much did each fish weigh?
Step-by-step explanation:
Let the cost of the larger fish be x, and the cost of the smaller fish be y.
From the question,
The cost of the larger fish was three times as great as the cost of the smaller fish, that is
x = 3y
Also, from the question,
The total cost of the two fish was $3,696, that is
x + y = $3,696
Since x = 3y, we can write that
3y + y = $3696
Now, we can determine y
3y + y = $3696
4y = $3696
y = $3696/4
y = $924
Hence, the cost of the smaller fish is $924
From x = 3y; we can determine x
y = $924
∴ x = 3y becomes
x = 3 × $924
x = $2772
Hence, the cost of the larger fish is $2772
Now, to determine how much each fish weigh,
From the question, A fish market bought two swordfish at a rate of $12 per pound
To determine the weight of each fish, we will divide the cost by the rate ($12 per pound)
For the larger fish
Cost = $2772
∴ Weight = $2772 ÷ $12 per pound = 231 pounds
Hence, the larger fish weigh 231 pounds.
For the smaller fish
Cost = $924
∴ Weight = $924÷ $12 per pound = 77 pounds
Hence, the smaller fish weigh 77 pounds.

Answer: see proof below
Step-by-step explanation:
Use the Cofunction Identity: sin (90 - A) = cos (A)
Use the Double Angle Identity: sin(2A) = 2 sinA cosA
Use the Triple Angle Identity: cos (3A) = 4cos³A - 3cosA
Use the Zero Product Property: If a · b = 0, then a = 0 or b = 0
Use Pythagorean Identity: cos²A + sin²A = 1 → cos²A = 1 - sin²A
Use Quadratic Formula: [tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Proof LHS → RHS:
Assumption: Let A = 18°
Multiplication: then 5A = 5(18°)
→ 5A = 90°
Expand: 2A + 3A = 90°
→ 2A = 90° - 3A
Apply sin: sin (2A) = sin (90° - 3A)
Cofunction: sin (2A) = cos (3A)
Double Angle: 2 sinA cos A = cos (3A)
Triple Angle: 2 sin A cos A = 4cos³A - 3cos A
→ -4cos³A + 3cos A + 2sinA cos A = 0
Factor: cos A(-4cos² A + 3 + 2sin A) = 0
Zero Product Property: cos A = 0 or -4cos² A + 3 + 2sin A = 0
↓
Disregard (since cos A ≠ 0)
Pythagorean: -4cos² A + 3 + 2sin A = 0
→ -4(1 - sin² A) + 3 + 2sin A = 0
→ -4 + 4sin² A + 3 + 2sin A = 0
Simplify: 4sin² A + 2sin A - 1 = 0
a=4 b=2 c= -1
[tex]\text{Quadratic Formula:}\qquad \sin A=\dfrac{-(2)\pm \sqrt{2^2-4(4)(-1)}}{2(4)}[/tex]
[tex]=\dfrac{-2\pm \sqrt{4+16}}{8}[/tex]
[tex]=\dfrac{-2\pm \sqrt{20}}{8}[/tex]
[tex]=\dfrac{-2\pm 2\sqrt{5}}{2(4)}[/tex]
[tex]=\dfrac{-1\pm \sqrt{5}}{4}[/tex]

Anna has $2.53. How much money will Anna have left if she buys a bright yellow highlighter and a thin blue marker?
thin green highlighter $0.35
package of crayons $0.61
thin blue marker $0.80
bright yellow highlighter $0.74
Answer:
$0.99
Step-by-step explanation:
A thin blue marker = $0.80
A bright yellow highlighter = $0.74
First, find the total cost of these two products. Add the costs together:
0.80 + 0.74 = 1.54
Anna has $2.53 in all. Subtract 1.54 from 2.53:
2.53 - 1.54 = $0.99
Anna will have $0.99 left.
