Answer: A

Step-by-step explanation:

(3,3) (6,5)

y2-y1/x2-x1 = 5-3/6-3 = 2/3

y-y1 = m(x-x1)

y-3 = 2/3(x-3)

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:

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:

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:

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:

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:

v = 60 yards

Step-by-step explanation:

In the similar triangles, their corresponding sides are proportional which means they have equal ratios

In triangles IHG and FHJ

∵ Δ IHG ≈ FHJ

∵ Side IH is corresponding to side FH

∵ Side HG is corresponding to side HJ

∵ Side IG is corresponding to side FJ

→ Their ratios are equal

∴ [tex]\frac{IH}{FH}[/tex] = [tex]\frac{HG}{HJ}[/tex] = [tex]\frac{IG}{FJ}[/tex]

∵ IH = 54 yards and FH = 72 yards

∵ IG = v and FJ = 80 yards

→ Substitute them in the first and last ratios above

∴ [tex]\frac{54}{72}[/tex] = [tex]\frac{v}{80}[/tex]

→ By using cross multiplication

∴ v × 72 = 80 × 54

∴ 72v = 4320

→ Divide both sides by 72

∴ v = 60 yards

Answer: The answer is 13,841,287,201

Step-by-step explanation:

You start with the equation that's in the parenthese which is  7^6, and the answer is 117,649. Then you're left with 117,649^2, so you solve for that which is 13,841,287,201. I'm not sure if this is what you're looking for but I hope this can help you.

Answer:

y=-1/2x+2

Explanation:

Answer:

75°

Step-by-step explanation:

In triangle FBG, one angle is 36.  That means the other two must total 180-36=144.  Assigning each one 72, their supplementary angle on the interior of the pentagon would be 108.

In triangle JDI, one angle is 39.  That means the other two must total 180-39=141.  Assigning each one 70.5, their supplementary angle on the interior of the pentagon would be 109.5

We now have 4 of the interior angles.  Pentagons have an interior total of 540.  540-108-108-109.5-109.5=105

x is the supplement of 105.  180-105=75

Answer: A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.

Answer:

Just thnk of it this way: Hetero- Different. Homo- Same

Step-by-step explanation:

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:

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).
