Answer: (B) SinA = 4/5

Step-by-step explanation: Sine= O/H or opposite of hypotenuse so in regards to the triangle opposite is 28 and hypotenuse 35 or 28/35 which also equals 4/5

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. A common symbol for a percentage is this symbol "%." Some abbreviations for it can be, "pct," or "pc."

Remember though that a percentage had no unit of measurement as it is a dimensions number.

Answer:

y = 4x + 13

Step-by-step explanation:

m = 4 at point (-3,1)

y = 4x + b

1 = 4(-3) + b

1 = - 12 + b

b= 13

y = 4x + 13

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

Slope is equal to the change in  y  over the change in  x , or rise over run.

m = change in y /change in x

The change in  x  is equal to the difference in x-coordinates (also called run), and the change in  y  is equal to the difference in y-coordinates (also called rise).

m = y 2 − y 1/ x 2 − x 1

Substitute in the values of  x  and  y  into the equation to find the slope.

m = 8 − ( 0 ) /3 − ( 1 )

Simplify.

Simplify the numerator.

m = 8 /3 − ( 1 )

Simplify the denominator.

Multiply  − 1  by  1

m = 8 /3 − 1

Subtract  1  from  3

m = 8/2

= 4

Answer:

x    10    4    6     1

y     5    2     3    0.5

Step-by-step explanation:

You have to start with a guess and see if it works. If it works, you're done. If it doesn't work, you need to make a difference guess.

I'll start by guessing that above the 0.5 is a 1.

If that is correct, then every x value is double the y value below it.

5 goes below the 10. 3 goes below the 6. Then you have 4 and 2 left.

That is every whole number from 1 to 5. It works.

x    10    4    6     1

y     5    2     3    0.5

Step-by-step explanation:

To find an equal number of numbers the sum has to be equal to 6*x.

Answer:

If he gave it all to his friends then its D. If it is counting him too then C.

Step-by-step explanation:

Answer:

its altitude is 8 cm

Step-by-step explanation:

1/2× base ×altitude =48

1/2×12× al =48

6×al =48

al = 8

[tex]x = - 3[/tex]

[tex]x + 3 = - x - 3[/tex]

[tex]x + 3 + x = - x - 3 + x[/tex]

Answer:

x > 5.4

One-half less-than x

x > 0

Step-by-step explanation:

use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to"

Answer:

if they have < or > then the inequality has and open circle

if they have [tex]\leq or \geq[/tex] then the inequality has a closed circle

Answer:

Decimal 0.333 to a fraction in simplest form is:   [tex]\frac{333}{1000}[/tex]

Step-by-step explanation:

Given the decimal

[tex]0.333[/tex]

Multiply and divide by 10 for every number after the decimal point.

There are three digits to the right of the decimal point, therefore multiply and divide by 1000.

Thus,

[tex]0.333=\frac{0.333\cdot \:\:1000}{1000}[/tex]

         [tex]=\frac{333}{1000}[/tex]         ∵ 0.333×1000 = 333

Let us check if we can reduce the fraction [tex]\frac{333}{1000}[/tex]

For this, we need to find a common factor of 333 and 1000 in order to cancel it out.

But, first, we need to find the Greatest Common Divisor (GCD) of 333, 1000

Greatest Common Divisor (GCD) :

The GCD of a, b is the largest positive number that divides both a and b without a remainder.

Prime Factorization of 333:      3 · 3 · 37

Prime Factorization of 1000:      2 · 2 · 2 · 5 · 5 · 5

As there is no common factor for 333 and 1000, therefore, the GCD is 1.

Important Tip:

Therefore, decimal 0.333 to a fraction in simplest form is:   [tex]\frac{333}{1000}[/tex]

Answer:

Cost of 1 sweet potato is $6.28 divided by 4 which will give $1.75

Answer:

$1.57

Step-by-step explanation:

What we know:

- There are 4 pounds of sweet potatoes

- 4 pounds of sweet potatoes cost $6.28

To find the cost per pound of sweet potatoes, divide $6.28 by 4.

6.28 ÷ 4

= $1.57

Therefore, the cost per pound of sweet potatoes is $1.57.
