if i have an 84 in a class, and i get a 64 on a test, what is my grade?​

Answer:

The answer will be 30cm

Because 40 divided by 4 is 10 and times it by 3

Answer:

[tex]27.82 \degree[/tex]

Step-by-step explanation:

To find the unknown angle use tan rule

[tex] \tan( \theta) = \frac{opposite}{adjacent} [/tex]

Let the unknown angle be x

[tex] \tan(x) = \frac{o}{a} \\ \tan(x) = \frac{19}{36} \\ \tan(x) = 0.5277 \\ x = \tan ^{ - 1} 0.5277 \\ x = 27.82 \degree[/tex]

Hope this helps you.

Answer:

-4/19 is the answer.

Step-by-step explanation:

Answer: 5[tex]\sqrt{3\\}[/tex]

Step-by-step explanation:

This triangle is a 30-60-90 triangle. This means that: x = 2a where a is the shorter leg of the triangle and x is the hypotenuse, and b = a[tex]\sqrt{3\\}[/tex] where b is the longer leg of the triangle.

Hypotenuse = 2 * the length of the shorter leg

Longer leg = [tex]\sqrt{3\\}[/tex] * the length of the shorter leg.

Since just visually speaking, y is the longer leg and 5 is the shorter leg, let's substitute y and 5 into the equation solving for the length of the longer side:

y = [tex]\sqrt{3\\}[/tex] * 5

y = 5[tex]\sqrt{3\\}[/tex]

Explanation:

Start at the point (-1,-4). In order to move to (0,0), we must do the following two steps:

This indicates slope = rise/run = 4/1 = 4.

You could use the slope formula to get this same result.

Answer: -0.5

-3.5 / 7 = -.5

The value is -1/2.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

-3.5 ÷ 7

This can be written as a fraction.

= -3.5/7

Remove the decimal point.

= -35/70

Divide both the numerator and denominator with 7.

= -5/10

Divide both the numerator and denominator with 5.

= -1/2

Thus,

The value is -1/2.

Answer:

Yes, because each domain have only one range.

Step-by-step explanation:

Answer:

Slope=4 y-intercept=(0,-21) or -21

Step-by-step explanation:

To find slope

m=-13-(-17)/2-1

m=4/1

m=4

To find y-intercept

y-(-17)=4(x-1)

y+17=4(x-1)

y+17=4x-4

Subtract both sides by 17

y=4x-21

y-intercept=-21

Answer:

8

Step-by-step explanation:

f(x) = (x+2)(x-2)

Substituting x=1 into f(x):

f(1) = 3*-1

     = -3

Since -2 & 2 touch the x-axis, 1 has a negative y value, 2 has a y value of 0, and all values from 2, are positive.

Hence,

3, 4, 5, 6, 7, 8, 9, 10 are all positive. Therefore, the answer is 8

This can be confirmed with a graph, as attached below.

Step-by-step explanation:

The distance between 2 points is calculated with this formula:

[tex] \sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2} } [/tex]

• in the first exercise:

- the leftmost point has values (-5; 1), where -5 is the value of x1 and 1 is the value of y1

- the rightmost point has values (4; 0), where 4 is the value of x2 and 0 is the value of y2

then apply the formula:

[tex] \sqrt{(4 - ( - 5)) {}^{2} + (0 - 1) {}^{2} } [/tex]

[tex] \sqrt{(4 + 5) {}^{2} + (- 1) {}^{2} } [/tex]

[tex] \sqrt{81 + 1} [/tex]

[tex] \sqrt{82 } =9.05[/tex]

you can check if the result is correct by counting the distance of the points with the squares of the sheet (photo)

• in the second exercise:

- the highest point has values (-4; 2), where -4 is the value of x1 and 2 is the value of y1

- the lower point has values (-4; -4), where -4 is the value of x2 and -4 is the value of y2

then apply the formula:

[tex] \sqrt{( - 4 - ( - 4)) {}^{2} + ( - 4 - 2) {}^{2} } [/tex]

[tex] \sqrt{(0) {}^{2} + (36) } [/tex]

[tex] \sqrt{36} = 6[/tex]

Answer:

6/14

Step-by-step explanation:

divide the numerator and denominator by 3. 18 / 3 is 6 and 42 / 3 is 14. So your answer is 6/14.

Answer:

6/14

Step-by-step explanation:

Scaling the numerator and denominator means to multiply or divide both numbers by some number. "Scaling down" means to divide both the numerator and denominator by some value (in this case, 3). So you would have to divide the numerator by 3 and the denominator by 3.

18 / 3 = 6

42 / 3 = 14

So you would get the equivalent fraction 6/14 when you scale down the numerator and denominator by 3.
