Can someone help who is good at pre algebra or algebra one? Tysm MAKE SURE ITS CORRECT (: I wanna get my math grade up

Answer:

See explanation

Step-by-step explanation:

If all the ten balls weigh 1,417.4 grams

Then 1 ball weighs 1,417.4 grams/10 = 141.74

To the nearest tenth = 141.7

To the nearest gram= 142

If someone asks me the weight of one ball I will give the answer as 141.7 because it contains exactly the same number of decimal points as we have in the question.

Answer:

1. The first factor is 1.267

2. 9 Places

3. i) The decimal point was moved to the left

ii) This indicates the value of the power of 10 in the second factor

4. The second factor is 10⁹

5. The population of India in scientific notation is 1.267 × 10⁹

Answer:

2

Step-by-step explanation:

(-4) + 6

remove the unnecessary parentheses

-4 + 6

calculate the sum which is

2

Answer:

2

Step-by-step explanation:

[-4] + 6 = 2

When two numbers are of different sign, subtract and the result will have the sign of bigger number.

Here the bigger number is 6 and it's sign is positive (+). So , the answer is +2

Answer:

The ship is approximately 21.6 miles away from its starting point

Step-by-step explanation:

∵ The North and the East are perpendicular

→ That means the distance between the starting position and

   the ending position shows a hypotenuse of a right triangle which

   its legs are the distances due to North and East

∵ The ship travels north for 18 miles

∴ leg1 = 18 miles

∵ The ship travels east for 12 miles

∴ leg2 = 12 miles

→ By using Pythagoras Theorem

∵ (hypotenuse)² = (leg1)² + (leg2)²

∴ (hypotenuse)² = (18)² + (12)²

∴ (hypotenuse)² = 324 + 144

∴ (hypotenuse)² = 468

→ Take √  for both sides

∴ hypotenuse = 21.63330765

→ Approximate it to the nearest tenth

∴ hypotenuse = 21.6 miles

∵ The hypotenuse of the right triangle represents the distance from

   the starting position to the ending position

∴ The ship is approximately 21.6 miles away from its starting point

Answer:

The messenger should use addition and Subtraction instead of multiplication and division

Step-by-step explanation:

It is given that,

A biker can ride a bicycle 18 miles in 3 hours. the messenger estimates that it will take 7 hours to bike 22 miles.

He has done two steps :

step 1: 22-18=4

step 2: 3+4=7

The steps done by the biker are wrong. The correct step should be :

In 1 hour, he should cover (18/3) miles i.e. 6 miles

In 7 hours, he will cover (6×7) miles i.e. 42 miles

It means he should use addition and Subtraction instead of multiplication and division. Hence, the correct option is (c).

Answer:

Step-by-step explanation:f(h(x))= 2x -21

f(x)= x^3 - 6

h(x)=\sqrt[3]{2x-15}

WE need to find f(h(x)), use composition of functions

Plug in h(x)

f(h(x))=f(\sqrt[3]{2x-15})

Now we plug in f(x) in f(x)

f(h(x))=f(\sqrt[3]{2x-15})=(\sqrt[3]{2x-15})^3 - 6

cube and cube root will get cancelled

f(h(x))= 2x-15 -6= 2 x-21

Answer:

The constant of proportionality for the group of boxes is: 25

Step-by-step explanation:

Proportion means that change in one quantity causes change in other quantity. Direct variation means that increase in one quantity causes increase in the other quantity.

Let l be the length and v be the volume

Then according to given statement

V∝l

Removing the proportionality symbol introduces a constant in the equation

[tex]V = kl[/tex]

Putting V = 325 and l = 13

[tex]325 =k(13)\\k = \frac{325}{13}\\k = 25[/tex]

Hence,

The constant of proportionality for the group of boxes is: 25

Answer:

A. 8 units

Step-by-step explanation:

Coordinates of A = (-2, -2)

Coordinates of C = (5, 2)

Use distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex] to calculate the length of diagonal [tex] \overline{AC} [/tex].

Let,

[tex] A(-2, -2) = (x_1, y_1) [/tex]

[tex] C(5, 2) = (x_2, y_2) [/tex]

[tex] d = \sqrt{(5 -(-2))^2 + (2 -(-2))^2} [/tex]

[tex] d = \sqrt{(7)^2 + (4)^2} [/tex]

[tex] d = \sqrt{49 + 16} = \sqrt{65} [/tex]

[tex] d = 8.1 [/tex] (nearest tenth)

Therefore, the closest to the length of diagonal [tex] \overline{AC} = 8 units [/tex]

Answer:

m=0; y intercept=3

Step-by-step explanation:

The line is perfectly horizontal, which means that the slope is 0. Since it is horizontal, we can reason that the y intercept has to be 3.

HTH :)

Answer:

The answer is 15.9 centimeters. If you work backward with the formula 2pir = circumphrence, you get diameter *pi = 50. To find diameter, you divide 50 by pi and the answer is 15.9 centimeters.

Step-by-step explanation:

The diameter to the nearest tenth of a centimeter is mathematically given as

31.8cm, option D

Question Parameters:

Circle Q has a circumference of approximately 50 centimeters.

Generally, the equation for the circumference   is mathematically given as

C=2\pir

Therefore

r=C/ \pi

r=50/3.14

r=15.9cm

Therefore,

d=2r

d=2*15.9

d=31.847

In conclusion, the diameter to the nearest tenth of a centimeter. is

31.8cm

Answer:

≈39.27 units

Step-by-step explanation:

To find the area of a semi circle, you use the formula for finding the area of a circle, which is [tex]\pi[/tex][tex]r^{2}[/tex], and then you divide that by 2 since it is half of a circle.

In this case, [tex]\pi[/tex][tex](5)^{2}[/tex] ≈ 78.54
