The sum of two numbers is 72. The greater number is 8 more than the smaller
number. Which equation can be used to solve for the smaller number? (1 point)
1) x - (x + 8) = 72
2) x + (x + 8) = 72
3) x(x + 8) = 72
04) x(x – 8) = 72

Answers

Answer:

2

Step-by-step explanation:

So first you would set your two numbers as variables. Let y be the greater number and x be the smaller number. This means that our equation for y will be x + 8. Now all we need to do is add x and y. INSTEAD of using y, we will SUBSTITUDE with the equation for y, x + 8. Now our equation looks like

x + (x + 8) = 72

Solve for x

In 2000, the population of Snowy Egrets went from 5,000 individuals to 15,000 individuals. What is the growth rate over those 4 years?

Answers

Answer:

[tex]x=\sqrt[4]{3}-1[/tex] or [tex]x=0.316[/tex]

Step-by-step explanation:

To write this equation you would need to use this equation for growth.

Final amount=initial amount (1+growth rate)^time

We have the final amount, 15,000, the initial amount, 5,000, and the time, 4 years. Now we have to plug in the values. We can write the growth rate as x.

[tex]15,000=5000(1+x)^4[/tex]

Now start by dividing both sides by 5000.

[tex]\frac{15000}{5000} =(1+x)^4[/tex]

[tex]3=(1+x)^4[/tex]

Now you can find the fourth root of both sides to get rid of the exponent.

[tex]\sqrt[4]{3} =1+x[/tex]

Finally, subtract 1 from both sides.

[tex]x=\sqrt[4]{3}-1[/tex]

And, if allowed, you can use a calculator to find the value in decimal form which would be:

[tex]x=0.316[/tex]

Answer: So you need to do the slope-intercept form  for y = mx+b so that you can find the slope of m.

Step-by-step explanation:

-y  =  3  −  2 x

Multiply each term:

1 y = 3⋅ −1 + (−2x)⋅ −1

y = 3. −1 + (−2x)⋅ −1

y=−3+(−2x)⋅−1

Answer:  GM = 18

==========================================================

Explanation:

Focus on triangle HKL. This is a right triangle with the horizontal leg KL = 2. The vertical leg is the unknown side HK. The hypotenuse is HL shown by the single tickmark.

Triangle HKJ is also a right triangle. It shares the leg HK and the hypotenuse JH is congruent to HL as indicated by the single tickmark.

By the hypotenuse leg theorem, we can show that triangle HKL is congruent to triangle HKJ

From there, the corresponding pieces JK and KL must be the same length. So we can say JK = 2 because KL = 2.

-------------------------------

Now use the segment addition postulate

GK = GJ + JK

GK = 7 + 2

GK = 9

Focus now on triangle GKH and triangle MKH. We can prove these are congruent triangles using the hypotenuse leg theorem. Here HK = HK as mentioned before; also, GH = HM due to the double tickmarks.

As you can probably guess by now, the hypotenuse leg theorem only applies to right triangles.

Since  triangle GKH is congruent to triangle MKH, we know that

GK = KM

Since GK = 9, this makes KM = 9.

---------------------------------

Therefore,

GM = GK + KM

GM = 9 + 9

GM = 18

A T-shirt takes ten minutes to make and a sweatshirt takes 20 minutes
to make. You have at most 20 hours to make shirts. The supplies for a
T-shirt cost $4 and the supplies for a sweatshirt cost $20. You want to
spend no more then $600 on supplies. You want to have at least 50
items to sell. How many T-shirts and how many sweatshirts should you
make to maximize your profit? The profit per T-shirt is $6 and the profit
per sweatshirt is $20,

Answers

I would use T-Shirts as sweatshirts make you no profit. 20 hours = 1200 / 10 (cuz it takes 10 min) = 120.

So you can make 120 shirts. 120 x4(for the cost of supplies) =$ 480.

you would make profit of 120 x 6 = 720.

720 - 480 = 240.

You would make $240 profit of making 120 shirts

What specific measure of a geometric figure is shown in the image? A. A 55mm side length B. A 180 mm side length C. A 55° angle D. A 125° angle (It may be A or C but idk)

Answers

Answer:

A 55° angle is a specific measure of a geometric figure is shown in the image. Therefore, option 'C' is correct.

Step-by-step explanation:

As protectors normally have two sets of numbers going in opposite directions.

As it is clear from the figure that the protector as the '0 mark' is the bottom edge of the protractor, while the 'center point' of the protector is being placed on the vertex of the angle.

From the figure, it is also clearly visible if we are able to read the degrees where the other ray of the angle is crossing the protractor, the protector is showing the 55° angle.

Therefore, a 55° angle is a specific measure of a geometric figure is shown in the image. Therefore, option 'C' is correct.
