A right triangle means that

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

[tex] {6}^{2} + {8}^{2} = {10}^{2} [/tex]

, which means that it follows the rules of the formula, making it a right triangle.

To create a line plot with a cluster around 6-8, you basically just group a lot of dots around the area (such as putting 4 dots over the dashes labelled 6-8). And for a gap between 4-5, just put one dot over 0-3.

The total dimension of the aquarium that will be cleaned by Steve will be 94 meters.

Your information isn't given. Therefore, an overview will be given. In this case, let's assume that the aquarium is rectangular. Let's assume the dimensions are 20m by 27m.

In this case, since she needs to clean the four walls of the aquarium, the total distance that will be cleaned will be:

= 2(Length + Width)

= 2(27 + 20)

= 2 × 47

= 94m

In conclusion, 94m will be cleaned.

Step-by-step explanation:

x² = 16

take the square root of both sides

x = ±4

there are 2 solutions to the equations, those 2 solutions being 4 and -4

just to double check

4² = 4 × 4 = 16

-4² = -4 × -4 = 16

Answer:

Similar

Step-by-step explanation:

We can say that the triangles are similar by looking at the angle measurements

Angle B = 35

Angle F = 55

Both angles A and D = 90 because these are right triangles

We can say the measure of angle E = 35 because the sum of angles in a triangle equal to 180

Same rule applies to angle C

Answer: x=12

√x+4 - 3 = 1

(√x+4 - 3) + 3 = 1 + 3

√x + 4 = 4

(√x+4)^2 = 4^2

√(x+4)^2 = 16

x+ 4 = 16 (cancels out the square root)

(x + 4) + (-4) = 16 + (-4)

x + 4 - 4 = 16 - 4

And then just solve it out

x = 12

5/100 because it's PERCENT, and well we need to put the 11600 out of 1.

Wich gives us

$580. THen, we multiply that by 6, (6 years). Which gives us

Answer:

45

Step-by-step explanation:

Since it given that her parent and grandmother attend a soccer game. Thus, we can see that there is no students.

Also given that:

Student tickets: $6

Non-Student tickets : $12

Parking : $9

Thus,

Non- Student tickets:$ 12 (Parents and grandmother are not students)

Parking: $9 ( Since they attend a soccer game they need somewhere to park)

Parents = 2 person (Mom and Dad)

Grandmother = 1 person

1 + 2 = 3

Now,

Since Non-student tickets = $12

3 * 12 +9

36 + 9

45

Hence, the family spend $45 to attend the game.

WEEK 8-140.710042266

By using an exponential equation, we will see that in the first 8 weeks she makes $954.90.

We know that the first week she makes $100, and for each week after that, she makes an extra 5%.

Then, the second week she makes:

W(2) = $100*(1 + 5%/100%) = $100*(1.05)

The third week she makes:

W(3) = $100*(1.05)*(1 + 5%/100%) = $100*(1.05)^2

We already can see the exponential pattern, for the N-th week, the salary will be:

W(N) = $100*(1.05)^(N - 1)

Then what she wins in the first 8 weeks is:

Now we just need to add these 8 values, we will see that the total money that she makes in these 8 weeks is:

M = $954.90

Answer:

750

Step-by-step explanation:

I multiplied the hours she worked by the amount of payment per hour.

Answer:

$750

Step-by-step explanation:

Since Lacey worked 40 hours with the condition that each hours, Lacey will be paid for $18.75, because they worked 40 hours, therefore:

[tex]\displaystyle \large{P = 18.75+18.75+18.75+...+18.75}[/tex]

From above, you add from first hour pay to 40th hour pay. However, that’d take quite a long time to evaluate:

[tex]\displaystyle \large{\sum_{H=1}^{40} 18.75 = 18.75 \cdot 40}[/tex]

Then evaluate 18.75 * 40 and therefore the solution is $750

For usage of formula:

P = RH for P = pay, H = hour and R = rate (pay per hour)

So if you use the formula, you’d still end up with P = 18.75*40 which is $750
