Answer 1

Answer:

273x

Step-by-step explanation:

-7x(-8²+25)

8²=64

-7x(-64+25)

-64+25=-39

-7x(-39)

-7×-39=273

273x

Answer 2

Answer: -623

-8 squared is 64 so that would give you the equation -7x (64+25)
then you would add 64 and 25 to get 89, giving you the equation -7 x 89.

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.

C) About 243 hits

Hey!! Please solve all CORRECTLY, I'm counting on you guys (i will also give brainliest and 20 points)

Answers

Step-by-step explanation:

The first one is B

x < 6 means that x cannot be 6, so only B or D works. But D is x > 6, so it's B

The second one is B

here, a filled circle means that x can be -6, so it's B or D again.

note that for these types of problems, choose a random number and see if it works. Let x = 0. Obviously, it's on the number line blue part, and it is greater than -6, so it's B

The third one is C

she has less than or equal to 45, but 45 is possible, so at most.

The last one is A. h > 4.5 means that h cannot be 4.5

So it's more, not at least.

So it's A

A I think probably a though

3. A ladder is 50 feet and cast a 25 foot shadow. Mark is 6 feet how long would his shadow be?

Answers

It’s 3 feet.
Since half of 50 is 25, half of 6 will be 3.

The shadow of 6 feet Mark will be 3 feet.

What is proportion ?

A proportion is an equation based on the equality of two ratios.

Here it is given that :

A ladder is 50 feet and cast a 25 foot shadow :

that is,

for each feet of ladder 0.5 feet shadow is casted.

now,

for 6 feet long Mark shadow will be :

0.5 x 6 feet = 3 feet

Therefore, the shadow of 6 feet Mark will be 3 feet.

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

The shoofly would then be clipped onto the favorite spot selected by each rider. So when the horses had their tails cleaned, the hair was saved for Sti'Tumma who then went to work to make herself some beautiful and colorful shooflies.
