Answer:

45/12

Step-by-step explanation:

first open the brackets +(-5½)= -5½

-7⅔-5½+8¾ put liketerms together

8¾-5½-7⅔

(find the LCM of the denominator 4,2,3 that is 12)

change the improper fraction to proper fraction 35/4-11/2-23/3.

(multiply by the 12 to make the denominator same)

(35/4x12)-(11/2x12)-(23/3x12)

105-66-92 = -53/12

=-45/12

PLEASE I need help on these 4 problems you don’t have to do them all but if you can at least do one of them TYSM

Answer:

For right angle triangle,

we use Pythagoras theorem that is:

$c^{2} =a^{2} +b^{2}$

c = $\sqrt{a^{2} +b^{2} }$

For question 1:

c = ?

a = 40

b = 9

putting them in formula,

c = $\sqrt{40^{2} + 9^{2} }$

c = 41

For question 2:

c = ?

a = 12

b = 13

putting them in formula,

c = $\sqrt{12^{2} + 13^{2} }$

c = approximately 17.69181

For question 3:

c = 35

a = 20

b = ?

putting them in formula,

$c^{2} =a^{2} +b^{2}$

$35^{2} = 20^{2} + b^{2}$

1225 = 400 + $b^{2}$

$b^{2}$ = 1225 - 400

$b^{2}$ = 825

$\sqrt{b^{2} } = \sqrt{825}$

b = 5 $\sqrt{33}$

For question 4:

c = 37

a = 20

b = ?

putting them in formula,

$c^{2} =a^{2} +b^{2}$

$37^{2} = 20^{2} + b^{2}$

1369 = 400 + $b^{2}$

$b^{2}$ = 1369 - 400

$b^{2}$ = 969

Taking square root on both sides

b = 31.12

Hope it helps.

ANSWER QUICK!!! IM TAKING A TEST AND I WILL MARK BRAINLIEST!!!

gtnhenbr [62]

Answer:

C = 5Q

Step-by-step explanation:

C = Length of Cloth in Meters (C)

Q = Number of Quilts Made (Q)

C = 5Q

Change C for the numbers under (Length of Cloth in Meters (C))
Nad change Q for the numbers under (Number of Quilts Made (Q))

So the new equations would be:

0 = 5(0) ---------> 0 = 0

5 = 5(1) ---------> 5 = 5

10 = 5(2) ---------> 10 = 10

15 = 5(3) ---------> 15 = 15

20 = 5(4) ---------> 20 = 20

25 = 5(5) ---------> 25 = 25

So the only option that amkes sense is (C = 5Q)

What is the probability of rolling a number less than 4 on a number cube?

monitta

Answer:

1/2, 50%

Step-by-step explanation:

A cube has six sides. The probability of landing on a number less than four is 3/6 because there are 3 positive numbers less than 4. 3/6=1/2=50%

Hope this helps!
