Answer:

D.) 38 cm²

Step-by-step explanation:

apologies if this isn't correct but I hope it is, anyway have a good day/night!

the area of the figure is 38.28cm².

The area of the shape is the sum of the area of the semicircle, a rectangle, and a right triangle.

Area of a semicircle = [tex]\frac{1}{2}[/tex]πr²

[tex]\frac{1}{2}[/tex]x 3.14 x (4/2)² = 6.28 cm²

Area of the rectangle = length x width

6 x 4 = 24 cm²

Area of the right triangle = [tex]\frac{1}{2}[/tex]x base x height

[tex]\frac{1}{2}[/tex]x (10 - 6) x 4 = 8cm²

Sum of the areas = 8 + 24 + 6.28 = 38.28cm²

225 thousandths × 72 hundredths

Answers

answer to 1. 9.45

Step-by-step explanation:first you have to multiple 2 x 5.3 = 10.6

then add 1.25 + 10.6 = 11.85

then subtract 11.85 - 2.4 = 9.45

answer to 2. 15.645

Step-by-step explanation:

becuase you put 15 for fifteen

and 645 thousandths

answer to 3. seven and fourteen hundredths

Step-by-step explanation:

just the same as 2 you just need to know decimal place value

answer to 4. (225x72)/1000000, 225 thousandths × 72 hundredths

Step-by-step explanation:

first you have to find out that 0.225 x 0.72 = 0.162

then check to see if the other options equal the same

2.25 x 7.2 = 16.2 so it dosen't match

(225x72)/1000000 = 0.162 so it dose match

225 × 72 × 0.001=16.2 so it dosen't match

225 thousandths × 72 hundredths= 0.162 so it dose match

The following linear equation represents the line of best fit for the following scatter plot

y=0.15x-1.5

Use the equation to answer the following questions. Predict the amount of hits a player would have to do to have 35 home runs.

A) About 4 hits
B) 223 hits
C) About 243 hits
D) 175 hits

Answers

Answer:

C) About 243 hits

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

We can use this to predict the average of the scatter plot.

home runs = y = 35

Step 2: Solve for x hits

Substitute [BLF]: 35 = 0.15x - 1.5Add 1.5 on both sides: 36.5 = 0.15xDivide 0.15 on both sides: 243.333 = xRewrite: x = 243.333

Remember that this is a prediction. According to the best line of fit, we would need approximately ~243 to get 35 home runs.

the answer would be 84 because 10*10=100 and .5 times 4*4 equals 16 and they are both right triangles so 100-16= 84

Triangle ABC is shown. A is at negative 2, 1. B is at negative 1, 4. C is at negative 4, 5. If triangle ABC is reflected over the y‐axis, reflected over the x‐axis, and rotated 180 degrees, where will point A' lie? (−1, 2) (−2, 1) (1, −2) (2, −1)

Answers

Answer:

B (-2,1)

Step-by-step explanation:

When you reflect over x axis the coordinates go from -2,1 to 2,1. When we rotate it 180, they go from 2,1 to -2,1. Point A will be at the same spot

plz mark brainliest

Point A' will lie at (b) (-2,1) after the transformation.

The coordinates of the triangle are given as:

[tex]A = (-2,1)[/tex]

[tex]B = (-1,4)[/tex]

[tex]C = (-4,5)[/tex]

The rule of reflection over the y-axis is:

[tex](x,y) \to (-x,y)[/tex]

So, the new coordinate of A is:

[tex]A =(2,1)[/tex]

The rule of reflection over the x-axis is:

[tex](x,y) \to (x,-y)[/tex]

So, the new coordinate of A is:

[tex]A =(2,-1)[/tex]

The rule of 180 degrees rotation is:

[tex](x,y) \to (-x,-y)[/tex]

So, the new coordinate of A is:

[tex]A = (-2,1)[/tex]

Hence, point A' will lie at (b) (-2,1)
