Answer:

Step-by-step explanation:

The sum of the smaller sides is not bigger than the largest side, 122. ( 31 + 89 = 120 < 122)

(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework? WILL MARK

Bess [88]

Assuming that $x$ is the amount of hours spent doing homework:

Plug in $3$ for $x$

$y = 8(3)+40$ , $y=64$

That means that since a $y$ value is the test score (because that's what the y-axis is labeled), your predicted test score is a 64.

6.81 is what percent of 45.5

frosja888 [35]

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 45.5 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 45.5 is 100%, so we can write it down as 45.5=100%.

4. We know, that x is 6.81% of the output value, so we can write it down as x=6.81%.

5. Now we have two simple equations:

1) 45.5=100%

2) x=6.81%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

45.5/x=100%/6.81%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 6.81% of 45.5

45.5/x=100/6.81

(45.5/x)*x=(100/6.81)*x - we multiply both sides of the equation by x

45.5=14.684287812041*x - we divide both sides of the equation by (14.684287812041) to get x

45.5/14.684287812041=x

3.09855=x

x=3.09855

now we have:

6.81% of 45.5=3.09855

Hope this helps!

Komodo dragons are the heaviest lizards on earth. A baby Komodo dragon is 1 3/4 feet long when it hatches. It’s mother is 8 3/4

sukhopar [10]

Answer:

An adult male Komodo dragon is $10\frac12$ feet.

Therefore the male is $1\frac34$ feet longer than the mother.

Step-by-step explanation:

Given that,

A baby dragon is $1\frac34$ feet long.

It's mother is $8\frac34$ feet.

An adult male Komodo dragon is 6 times as long as the baby Komodo dragon.

So, an adult male Komodo dragon is =(6× $1\frac34$ ) feet

$=6\times \frac74$ feet

$=\frac61\times \frac74$ feet

= $\frac {21}2$ feet.

$=10\frac12$ feet.

$\therefore 10\frac 12- 8\frac34$

$=\frac{21}{2}-\frac{35}4$

$=\frac{21\times 2-35\times 1}{4}$

$=\frac{42-35}{4}$

$=\frac74$

$=1\frac34$

Therefore the male is $1\frac34$ feet longer than the mother.
