stellarik [79]

Answer:

$44

Step-by-step explanation:

First, find how much he was making originally:

Multiply the number of hours he worked by the amount he got per hour:

20(8)

= 160

Then, find how much he gets now:

24(8.50)

= 204

To find his total weekly pay increase, find the difference between them:

204 - 160

= 44

So, his total weekly pay increase is $44

Simplify sqrt 8y/sqrt y

Eddi Din [679]

$\frac{\sqrt{8y} }{\sqrt{y} }$

Answer:

$2\sqrt{2}$

I turned the numerator into an exponent: $2 \frac{3}{2}$

$\frac{2^{\frac{3}{2}}\sqrt{y}}{\sqrt{y}}$

The $\sqrt{y}$ will cancel out, leaving $2 \frac{3}{2}$ .

$2^{\frac{3}{2}}=2\sqrt{2}$

Gobe weighs 53.6 kg. he wears shoes which weigh 450 gm and carries a school bag weighing 4.5 kg. if he stands on the scales in h

-Dominant- [34]

Answer:

The key to this question is converting all the mass units to the same unit and adding them all up.

The only value that isn't consistent with the other units is 450 gm or grams.

Recall that 1 gram is equal to 0.001 kilo grams. So if you want to convert grams to kilograms you would multiply that amount by 0.001 or 1/1000

$450gm * \frac{1}{1000} = 0.45kg$

Now let's add up all the masses.

$53.6kg + 0.45kg + 4.5kg = 58.55 kg\\$

(Now a few footnotes here, that I considered but wasn't sure about. The answer asks for weight, but you're only given mass to work with. That would be fine, if the question asked you to convert it to SI weight units like Newtons, but there's no mention of that. And also I'm not sure if the question requires significant digits. But I'll continue the answer if you think so)

To convert this into weight in Newtons, multiply by 9.81 m/s^2

$58.55kg*9.81m/s^2 = 574.3755 N\\\\= 5.7 * 10^2 N$

PLEASEE HELPPP!!!

Harlamova29_29 [7]

Answer:

The amount is $649.46 and the interest is $49.46.

Step-by-step explanation:

STEP 1: To find amount we use formula:

A=P(1+rn)n⋅t

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

In this example we have

P=$600 , r=8% , n=4 and t=1 years

After plugging the given information we have

AAAA=600(1+0.084)4⋅1=600⋅1.024=600⋅1.082432=649.46

STEP 2: To find interest we use formula A=P+I, since A=649.46 and P = 600 we have:

A649.46II=P+I=600+I=649.46−600=49.46
