Step-by-step explanation:

A team of biologists tagged 48 seals off the coast of an island.

later they captured a sample of seals from the same area and 15% of them had tags.

Estimate the total number of seals.

15 : 100 : : 48 : x

x

=4,800/15

=320

The total number of seals is about 320.

Monday Bellwork Which solution would make this equation have infinitely many solutions? 6(x – 3) + x = 7x +

-18, -9, 18, or 9​

Answers

Answer:-18

Step-by-step explanation:

6(x−3)+x=7x−18

Step 1: Simplify both sides of the equation.

6(x−3)+x=7x−18

(6)(x)+(6)(−3)+x=7x+−18(Distribute)

6x+−18+x=7x+−18

(6x+x)+(−18)=7x−18(Combine Like Terms)

7x+−18=7x−18

7x−18=7x−18

Step 2: Subtract 7x from both sides.

7x−18−7x=7x−18−7x

−18=−18

Step 3: Add 18 to both sides.

−18+18=−18+18

-20t>-80 what is t and how do you graph it on a nuberline

Answers

Answer:

Step-by-step explanation:

Divide both sides by -20. If you divide by a negative, you have to switch the inequality sign. So now you have this for t:

t < 4

Draw a circle around 4 on a number line, but do not shade it in. Then everything below 4 is the right answer for the value of t.

what do you call a crushed angle ?

Answers

Answer:

A Rectangle

Step-by-step explanation:

a wrecked angle

A crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".

When an angle is crushed or collapsed, its sides are no longer straight or evenly spaced, and its vertex may be shifted or deformed.

This deformation can occur in various contexts, such as in physical objects or in mathematical diagrams. The angle's original shape has been significantly changed due to external influences.

Thus, a crushed angle is commonly referred to as a "rectangle" or a "wrecked angle".

This is a play on words, as a rectangle is a shape with four right angles, and when an angle is crushed or wrecked, it can resemble a rectangle.

If f(x)= -2x+3 , find f(-1)?

Answers

Before we solve the equation let's take a look at it.

f(x) = -2x + 3

See how x appears in both f(x) and as the variable in the second half of the equation?

f(x) means "The function of x." You might also see g(x), h(x), and while those are the most common it can really be any letter, and any variable inside the parentheses.

So when we see f(-1), that means "The function of -1" or "The function of x when it is equal to -1."

Catching on? We need to replace x with -1 to solve for f(-1).

So here we go:

f(x) = -2x + 3

f(-1) = -2(-1) + 3

f(-1) = 2 + 3

f(-1) = 5

Voilà! We have solved for f(-1). Hope this helped.
