Evaluate the expression

I am Lyosha [343]

Answer:

36

Step-by-step explanation:

Given expression:

$(10 - 3 + 5)^{2}} \times \dfrac{1}{4}$

Simplify the expression in the parenthesis

$\implies (12)^{2} \times \dfrac{1}{4}$

Simplify the exponents in the expression:

$\implies (12) \times (12) \times \dfrac{1}{4}$

$\implies 144 \times \dfrac{1}{4}$

∴ Recall that: (a × 1/b = a ÷ b)

$\implies 144 \div 4$

Simplify the expression:

$\implies 144 \div 4$

$\implies \boxed{36}$

I need answers for answers 77 thru 82 please it's due tommorow

coldgirl [10]

77. 0.205 < 0.21
It's less by 0.005
78. 0.1 = 0.1000
The extra zeroes do not change the solution.
79. -0.04 > -0.050
While this might look greater, remember to check the number line position
80. -1.03 < -0.03
Same as the last one.
81. $\frac{5}{10}$ < 0.6
$\frac{5}{10}$ = 0.5 < 0.6
82. - $\frac{3}{5}$ < -0.03
Same process as 80 mixed with 81.

I hope that these help.

The Social Security (FICA) wage base ,y, (in thousands of dollars) from 1983 to 1988 is given by the equation y=1.9x+34.1, where

Zinaida [17]

Answer:

Step-by-step explanation:

Given the equation of the Social Security (FICA) wage base y, (in thousands of dollars) from 1983 to 1988 expressed as y=1.9x+34.1

for us to calculate his wage base in 1995, we need to calculate the total number of years between 1983 to 1995 i.e 12 years

Substitute x = 12 into the expression above as shown;

y=1.9x+34.1

y = 1.9(12)+ 34.1

y = 22.8 + 34.1

y = 56.9

Since y is in thousand of dollars then

y = 56.9 * 1000

y = 56900

y = $56,900

Hence FICA wage base in 1995 is $56,900

Give brainiest if right!

Ne4ueva [31]

Answer:

Step-by-step explanation:

First we are going to set up our general equation (what is being asked of us). Marina bought pears, pineapples, and kiwis and spent $13.50 on them. The equation for that is

pi + pe + k = 13.5

Now we need to figure out how to eliminate most of those unknowns and put 2 of them in terms of the other 1. It looks like everything is based on the number of pineapples she bought. First it says she bought 9 more pears than pineapples, so obviously, there are more pears than pineapple, so

pe = pi + 9

And if she bought 2 fewer than kiwis thatn pears, and pears = pi + 9, then the number of kiwis she bought was

kiwis = (pi + 9) - 2 which simplifies down to pi + 7.

Now we'll put all of those into the equation:

pi + (pi + 9) + (pi + 7) = 13.5 What I have done is create an equation that is not parallel. In other words, I have the NUMBER of the kinds of fruit on one side of the equation, and the COST of the fruit on the other side, and that's not cool. We have to have EITHER a NUMBER of fruit equation OR a COST of fruit equation, but not both in the same equation. To amend that, we will figure in the cost of each of these kinds of fruit by the correcpsonding number of that kind of fruit. Pineapples cost $1.50 each, so the expression for pineapples is 1.5pi; pears cost $.50 each, so the expression for pears is.5(pi + 9); kiwis cost $.30 each, so the expression for kiwis is .3(pi + 7). NOW we can set up the equation:

1.5pi + .5(pi + 9) + .3(pi + 7) = 13.5 and simplify:

1.5pi + .5pi + 4.5 + .3pi + 2.1 = 13.5 and simplify some more by combining like terms:

2.3pi = 6.9 so

pi = 3. Ok we have 3 pineapples. Now we go back up to the expression for pears:

pe = pi + 9 so

pears = 12. Now we go back to the expression for kiwis:

k = pi + 7 so

kiwis = 10. And there you go!
