Ava is a high school basketball player in a particular game she made some three point shots and some two point shots Ava made a total of 12 shots altogether and scored a total of 28 points how many of the points were three points and how many were 2 points

Answers

Answer:

Ava made 4 three point shots and 8 two point shots.

Step-by-step explanation:

Let X represent the number of 3-point shots and Y represent the number of 2-point shots.

Then using the provided data two equations can be formed:

X + Y = 12...(i)

3X + 2Y = 28...(ii)

Solve (i) and (ii) simultaneously:

Multiply (i) by 2 and subtract (ii) from (i) as follows:

2X + 2Y = 24

-3X - 2Y = -28

-X = -4

X = 4

Substitute X = 4 in (i) and solve for Y as follows:

X + Y = 12

4 + Y = 12

Y = 8

Thus, Ava made 4 3-point shots and 8 2-point shots.

C. x = 4√3, 7-72
D. x=753, y = 4√2

Answers

Answer:

[tex]x= 7, y=4\sqrt{2}[/tex]

Correct option B.

Step-by-step explanation:

The diagram shows a trapezoid with a base angle of 45° and the other base angle of 90°.

We have completed the diagram to draw a perpendicular line over the base of height h=4. A triangle is formed with an angle of 45°.

Recall a right triangle with angles of 45° is isosceles, thus the base and the height are h=4. Please check the diagram below.

For that triangle, we apply Pythagora's Theorem:

[tex]y^2=4^2+4^2=2*4^2[/tex]

Thus:

[tex]y=\sqrt{2*4^4}=4\sqrt{2}[/tex]

[tex]y=4\sqrt{2}[/tex]

The base of the trapezoid x is h + 3 = 7

Thus:

[tex]\mathbf{x= 7, y=4\sqrt{2}}[/tex]

Correct option B.

Convert 8/9 to its decimal form and round to the nearest thousandth

Answers

To figure out what a fraction is as a decimal u would do the top divided by the bottom

For this fraction it would look like this,

8 divided by 9 which would get you 0.88888888888

So your decimal is 0.889

Its not 0.888 because with decimals since a typical decimal is show as 2-3 numbers it would be rounded up to keep it as 3 numbers or less. so this would be 0.889 or if that doesnt work 0.888 with a line over the last 8.

Answer:

0.889

Step-by-step explanation:

0.88888888 repeating the 3rd 8 is the thousandth place so you look at your neighbor and it is 5 or higher so you round up to 0.889

In parallelogram ABCD, the measure of angle A=3x and the measure of angle B =x+10. What is the measure of angle D?

Answers

Answer: 52.5

Step-by-step explanation: 2(3x+10)+2(x+10)=360 because all the sides of a rhombus equal 360 and alternate sides are equal

8x+20=360

-20=-20

8x/8=340/8

x=42.5

x+10. 42.5+10=52.5

D=52.5

The measure of ∠D in parallelogram ABCD is 52.5°.

What is a parallelogram?

A parallelogram is a 2D figure in which opposite sides are equal.

We know in a parallelogram sum of the adjacent angles is 180° and opposite angles are equal.

∴ In a parallelogram, ABCD ∠A = ∠C and ∠B = ∠D and we also know that sum of all the interior angles of a parallelogram is 360°.

∴ ∠A + ∠B + ∠C + ∠D = 360°.

2∠A + 2∠B = 360°.

2(3x) + 2(x+10) = 360°.

6x + 2x + 20° = 360°.

8x = 340°.

x = 42.5°.

Given, ∠B = ∠D = x + 10° = 42.5° + 10° = 52.5°.
