60 I think because 180 / 3 = 60 so i think it’s correct

Answer:

60°

Step-by-step explanation:

A triangle is 180°, and if the angles are equal you divide 180 by 3 to get 60.

Solve photo question. Mathematics.

Aneli [31]

Take two points to find the slope
Let;s take (1, -3) and (-3, -1)

Point slope formula is

m = $\frac{y2-y1}{x2-x1}$
or
y₂-y₁ = m×(x₂-x₁) Which is the same thing

m = $\frac{-1-(-3)}{-3-1}$
= $\frac{2}{-4}$
It can be simplified:
= $-\frac{1}{2}$
Now we found the slope

Same formula:
y₂-y₁ = m × (x₂-x₁)
Substitute the point only (1, -3)
y₂-(-3) = $-\frac{1}{2}$ × (x₂-1)
y₂ + 3 = $-\frac{1}{2}$ × (x₂ - 1) (minus minus = plus)

The last option is the answer

Suppose a parabola has vertex (5,-3) and also passes through the point (6, 1). Write the equation of the parabola in vertex form

Alchen [17]

General form for vertex form is:

y = a(x - h)² + k

Where the vertex is the point (h, k). We know this to be (5, -3), so we can substitute the values for h and k to get:

y = a(x - 5)² - 3

We then also have another point (6, 1) that gives us an x and y. Substitute those in to leave one unknown which we can solve for:

1 = a(6 - 5)² - 3

1 = a(1)² - 3

1 = a(1) - 3

1 = a - 3

4 = a

So the equation of this parabola in vertex form is:

y = 4(x - 5)² - 3

Josie is trading for a race. The ratio of the number of minutes to the number of miles she runs is 24 to3 she plans to run ten m

belka [17]

Answer:

Step-by-step explanation:

The ratio can be simplified and rewritten:

minutes : miles = 24 : 3 = 8 : 1 = 80 : 10

It will take Josie 80 minutes to run 10 miles at her 8 minutes/mile pace.

Which of the following is the equation that says that the product of a number and ten is equal to 20 percent of that number ?

Savatey [412]

Answer:

It is D.

Step-by-step explanation:

The produce of the number and 10 is 10n.

20 percent of the number = 0.20n.
