Answer:

35 bricks for $25.90

230 bricks for $170.2

Step-by-step explanation:

Cost per brick = number of bricks / price of bricks

1500/$1110 = $1.35

1300 / $845 = $1.54

230 / $170.20 = $1.35

100 / $75 = $1.33

35 / $25.90 = $1.35

Based on these calculations, the bricks that have the same cost per brick are :

35 bricks for $25.90

230 bricks for $170.20

Suppose your dog posit $250 in a new savings account paying a Yield of 3% interest if the count is left alone how much money wil

Fed [463]

Answer:

The amount after a time period of 5 years is $287.5.

Step-by-step explanation:

Principal Amount deposited = $250

Time = 5 Years

Rate of interest = 3%

Now, SIMPLE INTEREST = $\frac{P \times R \times T}{100}$

⇒ $SI = \frac{250 \times 3 \times 5}{100} = 37.5$

or, the interest amount after 5 years = $37.5

Now, AMOUNT = PRINCIPAL + INTEREST

= $250 + $37.5 = $287.5

Hence the amount after a time period of 5 years is $287.5.

Find the common ratio for the following sequence .1, .01, .001

morpeh [17]

Answer:

0.1

Step-by-step explanation:

The common ratio of a sequence is the number you multiply one term to get the next one. Here, we multiply 0.1 by 0.1 to get 0.01, and 0.01 by 0.1 to get 0.001, so our common ratio is 0.1.

Help pls :( Solve for x. -4 + 3x = 20

prohojiy [21]

$\huge\text{Hey there!}$

$\large\textsf{-4 + 3x = 20}\\\rightarrow\large\textsf{3x - 4 = 20}\\\\\large\text{ADD 4 to BOTH SIDES}\\\large\textsf{3x - 4 + 4 = 20 + 4}\\\large\text{CANCEL out: \textsf{-4 + 4} because that gives you \textsf 0}\\\large\text{KEEP: \textsf{20 + 4}} \text{ because it gives you the \textsf{x-value}}}\\\\\large\textsf{20 + 4 = \bf 24}\\\\\large\text{DIVIDE 3 to BOTH SIDES}\\\\\mathsf{\dfrac{3x}{3}= \dfrac{24}{3}}\\\large\text{CANCEL out: }\mathsf{\dfrac{3}{3}}\large\text{ because that gives you \textsf 1}$

$\large\text{KEEP: }\mathsf{\dfrac{24}{3}}\large\text{ because it helps gives you the result of the \textsf{x-value}}\\\\\mathsf{x = \dfrac{24}{3}}\\\\\large\textsf{x= 24}\div \large\textsf{3}}\\\large\textsf{x = \bf 8}\\\\\boxed{\boxed{\huge\text{Therefore, your answer is: \textsf{x = 8}}}}\huge\checkmark$
