Answer: X=1.5

Step-by-step explanation:

Solution

Perimeter= 2(l+w)

25= 2( 3x+4 +2x+1)

25= 2(3x+2x+4+1)

25= 2(5x+5)

25= 10x+10

Now subtract 10 on both sides..

25-10= 10x+10-10

15=10x

Now divide 10 on both sides to get x

15/10= 10x/10

1.5=X

If 433 = 100% then what percent does 383 equal

Goryan [66]

Answer:

88.46%

Step-by-step explanation:

433 - 383 = 50

50 ÷ 433 = 0.1154

0.1154 x 100 = 11.54%

100% - 11.54% = 88.46%

<u>Check work:</u>

433 x 88.46% = 383

HELP PLEASE <br> solve the right triangle

aleksandrvk [35]

Answer:

Part 1) $FG=4.4\ units$

Part 2) $EF=3.9\ units$

Part 3) $m\angle G=63^o$

Step-by-step explanation:

step 1

Find the measure of length side FG

In the right triangle EFG

we know that

$sin(27^o)=\frac{GE}{FG}$ ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

$sin(27^o)=\frac{2}{FG}$

$FG=\frac{2}{sin(27^o)}=4.4\ units$

step 2

Find the measure of length side EF

In the right triangle EFG

we know that

$cos(27^o)=\frac{EF}{FG}$ ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

$cos(27^o)=\frac{EF}{4.4}$

$EF=cos(27^o)(4.4)=3.9\ units$

step 3

Find the measure of angle G

we know that

$m\angle G+27^o=90^o$ ---> by complementary angles in a right triangle

$m\angle G=90^o-27^o=63^o$

What is 67/7 as mixed number

monitta

Answer:

9 4/7

Step-by-step explanation:

First, we need to make as many 7s as possible. If we do 67/7, we will get 9...... so our whole number is 9. If we do 7 x 9, we get 63 and if we subtract 63 from 67, we are left with 4. All in all, we will get 9 4/7!
