enot [183]

Given :

Number of hours studied daily , $T=5\dfrac{2}{3}$ .

Time given for science and mathematics is , $t=2\dfrac{4}{2}$ .

To Find :

How much time does she devote for other subjects .

Solution :

Let , time devote for other student is x .

So , Time left for other subject = Total time - Time taken by science and mathematics .

$x=T-t\\\\x=5\dfrac{2}{3}-2\dfrac{4}{2}\\\\x=\dfrac{(5\times 3)+2}{3}- \dfrac{(2\times 2 )+4}{2}\\\\x=\dfrac{17}{3}-4\\\\x=\dfrac{17-(4\times 3)}{3}\\\\x=\dfrac{5}{3}=1\dfrac{2}{3}$

Therefore , time devote for other subject is $1\dfrac{2}{3}$ hours .

Hence , this is the required solution .

What’s the missing side round to the nearest tenth?

Step2247 [10]

Sine of angle = opposite ÷ hypotenuse

sin 20 = $\frac{14}{x}$

x = $\frac{14}{sin 20}$

x = 40.9 (rounded up to nearest tenth)

At the fair 4 employees were paid $8.75 an hour to work at a funnel cake stand. They worked 8 hours at regular pay then for 5 ho

nordsb [41]

Answer:

$125.25

Step-by-step explanation:

8.75*h+11.25*e

h is hours regular pay and e is extra pay for overtime. Since its an extra $2.50 for overtime, add that to the regular pay. Put in the hours:

$8.75*8+11.25*5$

Simplify by multiplying 8.75 by 8

$70+11.25*5$

Simplify by multiplying 11.25 by 5

$70+56.25$

Add

$70+56.25=126.25$

Since it says how much did each earn, as in individually, leave it as it is (unless regular pay was $2.18 an hour, which would be a rip-off). I'm pretty sure including the number of employees was meant to throw you off.

Which computation should be done last 2x9 -3x5+4?

SVETLANKA909090 [29]

2 x 9 - 3 x 5 + 4

In math/s we have the rule called BEDMAS
(a.k.a. BODMAS, BIDMAS, PEDMAS, etc)

Brackets
Exponent
Division
Multiplication
Addition
Subtraction

We go from top to bottom of the list of rules for every math equation. There’s just one exception, addition and subtraction are treated equally, and so when we have an equation with just addition and subtraction, we work left to right

2 x 9 - 3 x 5 + 4

We have no brackets and no exponents, and there’s nothing to divide.
So, we do multiplication
18 - 15 + 4

If you remember, addition and subtraction are treated the same. Therefore, we work left to right.
18 - 15 + 4 = 7

You can type your question into goorgle or a calculator, and you’ll get 7!
