A pound of ground beef costs $5. what is the cost of 1/2 pound?

Answers

Answer:

$2.50

Step-by-step explanation:

x/5 = 1/2

x is equal to 1 because it is half of the total and 1 is half of 2.

5 is equal to 2 because it is the whole amount and 2 is also the whole amount.

If you then solve for x by doing

5(1) = 5

5/2 = 2.5

You get 2.5 or $2.50.

Answer:

simple $2.50

Step-by-step explanation:

Table 4 is showing proportional relationship between weight and price.

What is proportionality?

The number or amount of a group or part of something when compared to the whole, is considered as proportionality.

Given that, a table of proportional relationship between weight and price;

If we consider table number 4,

We see, weight : price = 2 : 4 = 1 : 2

And, 4 : 8 = 1 : 2

Therefore, this is showing proportionality,

Hence, Table 4 is showing proportional relationship between weight and price.

A family plans to water ski at a local lake. If the temperature outside is 30 degrees C, what is the temperature in degrees F? Use the formula F = 9/5 C + 32 ?

Help


Answers

30 degrees C = 86 degrees F

Answer:

30°C = 86°F

Step-by-step Explanation:

Temperature outside in degree celsius = 30°C

Formula to convert degree celsius to degree fahrenheit:

[tex] \boxed{ \bf{\degree F = \dfrac{9}{5}\degree C + 32}}[/tex]

By substituting value in the formula, we get:

[tex] \rm \implies \degree F = \dfrac{9}{5} \times 30 + 32 \\ \\ \rm \implies \degree F = 9 \times 6 + 32 \\ \\ \rm \implies \degree F = 54 + 32 \\ \\ \rm \implies \degree F = 86[/tex]

[tex] \therefore [/tex] Temperature outside in degree fahrenheit = 86°F

ΔABC is dilated using a scale factor of 12 to produce ΔA'B'C'. Select all of the statements that apply to the transformation.

Answers

Answer:

Options (3) and (6)

Step-by-step explanation:

ΔABC is a dilated using a scale factor of [tex]\frac{1}{2}[/tex] to produce image triangle ΔA'B'C'.

Since, dilation is a rigid transformation,

Angles of both the triangles will be unchanged or congruent.

m∠A = m∠A' and m∠B = m∠B'

Since, sides of ΔA'B'C' = [tex]\frac{1}{2}[/tex] of the sides of ΔABC

Area of ΔA'B'C' = [tex]\frac{1}{2}(\text{Area of triangle ABC})[/tex]

Area of ΔABC > Area of ΔA'B'C'

Since, angles of ΔABC and ΔA'B'C' are congruent, both the triangles will be similar.

ΔABC ~ ΔA'B'C'

Therefore, Option (3) and Option (6) are the correct options.

Answer: The Third option and the sixth option.

(QUICKKKKKK ILL GIVE BRAINLIEST) How many pages can Jorge print in 3/5 of an hour if he can print 24 pages every 15 minutes? NOT 3/4, ITS 3/5.

Answers

Answer:

58 pages

Step-by-step explanation:

If Jorge can print 24 pages in 15 minutes, that means he can print 4 times as much in an hour (or 24*4=96 pages in 1 hour).

Since we need 3/5 of an hour, we just multiply 3/5 with 96 to get 57.6 pages.

So the approximate answer is 58 pages
