HERE YOU GOOOO

Answer:

1) B is the answer

2) C is the answer

Step-by-step explanation:

1) 21:40=0.525

2) 21:40=0.525=52.5%

Because with percents it has to be out of 100 so 0.525 is not out of a hundred so multiply 0.525 times 100 to get 53.5%.

The coordinates of a point on a coordinate grid are (−1, 5). The point is reflected across the x-axis to obtain a new point. The coordinates of the reflected point are (1, −5) (−1, 5) (1, 5) (−1, −5)

Answers

Answer:

I think it should be (-1,-5)

Step-by-step explanation:

On a coordinate grid, when you flip this coordinate across the x-axis, the x-axis number won't change, meaning that -1 will stay. The intial number was in the second quadrant, this means that the new number will be in the third quadrant which is made up of all negative numbers. This means that 5 will now be graphed as negative 5, making (-1,-5) the correct answer in this situation.

Which of the following equations is equivalent to ab − 8 = 3b, when solving for b .
a = 11
b = 8/2a
b = -8/3 - a
b = -8/a - 3

Answers

It would be B=-8/a-3

The equivalent equation for the given equation is b=8/(a-3).

What is an equivalent equation?

Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.

The given equation is ab-8=3b.

Now, transpose 3b to other sides of an equation, we get

ab-3b=8

b(a-3)=8

b=8/(a-3)

Therefore, the equivalent equation for the given equation is b=8/(a-3).

First, we must determine slope using the given points and pluging them in the slope formula*.

[tex]m = \frac{6 - (-6)}{2 - (-4)} = \frac{12}{6} = 2[/tex]

The slope is 2. You can prove this by using the graph.

Second, we plug in the slope we found, and one of the given points to solve for b using slope-intercept form**.

[tex]6 = 2(2) + b\\\\6 = 4 + b\\\\2 = b[/tex]

The y-intercept (or b) is 2. You can prove this by using the graph.

Finally, we can now create the equation of the line in slope-intercept form.

[tex]y = 2x + 3[/tex]

*Slope formula: y₂ - y₁/x₂ - x₁

**Slope-intercept form: y = mx + b

6. When Landon saves $15 more, he will have enough money to buy a basic MP3 player. The player he wants to buy costs $199, which is 4 times the cost of the basic player. Which equation could be used to determine n, the number of dollars Landon has already saved?

A. 4n +15 = 199 B. 4(n+15) = 199 C. n + 4(15) = 199

Answers

Answer:

A) 4n+15=199

Because n is the cost of the basic player, so 4*n would be the cost of the player he wants. Also +15 since he needs 15 more dollars.

The ratio of a drawing to an object is 6 cm: 40 cm. If the length of the drawing is 36 cm, what is the actual length of the object?

Brainleast? I mean if u give me an answer and an explanation pls.

Answers

Answer:

240

Step-by-step explanation:

If the length of the drawing is 36cm, then we divide 36 by 6, which then equals 6...

Since we changed the 6,  we have to change the 40...

40 x 6 = 240

so the ratio is 36:240 and the object's length equals 240cm

The actual length of the object is 240.
