Answer:

So what we need to do first is single out t. So 7/3 times 4 (as 4 divides on the right it's gonna multiply on the left). Multiplying numerators together 7*4 gives 28 with 3 in the denominator. So it'll look like 28/3. Division must give you

t = 9.33

Have a nice day!!

This question has already been set up as a proportion. You start by cross multiplying. 7 times t is equal to 7t. 3 times 4 is equal to 12. You now have the equation 7t = 12. Now you use the division property of equality, meaning you divide both sides of the equation by 7. 7t divided by 7 equals t. 12 divided by 7 equals approximately 1.7. Then you are left with the equation t=1.7.

Answer:

D)22.5cm

CB/BA=HG/13.5

CB=15cm,BA=9cm,HG=x and GF=13.5

15/9=x/13.5(divided by 13.5both sides)

x=22.5cm

Please help, I don't understand part a or b.

Serggg [28]

Part A
25-9=16
16/2=8
The length of the rope holding the top right corner of the banner to the post is 8 feet long

Part B
13-9-2= 2 for width
25-8=16 16/2=8 for length
Use the Pythagorean Theorem
$a^{2}$ + $b^{2}$ = $c^{2}$
$8^{2}+ 2^{2}= c^{2}$
64+4= $c^{2}$
68= $c^{2}$
$\sqrt{68}= \sqrt{c}$
34=c
The length of the rope from the bottom right corner of the banner to the post is 34 feet

Complete the table, will choose brainliest.

Answer:

68% 32%

73.5% 26.5%

Step-by-step explanation:

Start:

total number = 561 + 264 = 825

glucose aversion = 561

percent = 561/825 × 100% = 68%

no glucose aversion: 264

percent = 264/825 × 100% = 32%

End:

total number = 441 + 159 = 600

glucose aversion = 441

percent = 441/600 × 100% = 73.5%

no glucose aversion: 159

percent = 159/600 × 100% = 26.5%

The amount of money a worker makes varies directly with the hourly rate of pay. Worker A earns $168 for an 8 hour period. Worker
