Answer:

y= -1.5x+15

Step-by-step explanation:

y=mx+b

This is the formula to find the equation. M is the slope (rise over run), and b is the y-intercept. Hope this helps.

Kendall has 37 inches of yarn to create an outline of the Big Dipper for her science project. Which equation could be used to fi

ss7ja [257]

Answer:

The equation could be used to find out how many inches of yarn will be left when Kendall has finished the project is option D. Not enough information is given

Solution:

Given, Kendall has 37 inches of yarn to create an outline of the Big Dipper for her science project.

We have to find which equation could be used to find out how many inches of yarn will be left when she has finished the project?

In order to find how many inches of yarn left we just need to subtract the used amount of yarn from available piece of yarn, but we are not given any information about the amount of used piece of yarn.

So, not enough information is given,

Hence, option d is correct

Wouldnt it be 15??? I would guess so. Katie keeps deleting this but Im not sure why. Sorry katie but I really need help

Anna007 [38]

Answer:

25 in; C

Step-by-step explanation:

Hey!

There probably is a reason she is deleting. You could contact her or ask some help elsewhere.

Anyway! I'm trying to get this in fast. (Remember the Pythagorean Theorem?) That will be very useful here since it is a right triangle.

L² + L² = H² (or H² - L² = L²):

In that case, we'll use the second one because our Hypotenuse is given.

We can substitute each value of the numbers:

65² - 60² = L²

Evaluating:

4225 - 3600 = 625

√625 = 25 inches

Thusly, the third side would be $\boxed{25{\text{\:inches\:or\:C.}}}$

Also note we could have simplified into a Pythagorean Triple. This method is a simpler more basic method for learning the concept.

Hope this helps!

It takes flora 3 hours to knit a pair of socks and 7 hours to knit a pair of gloves. If she spent 65 hours knitting a total of 1

IRINA_888 [86]

Answer:

Flora can make 10 pairs of socks and 5 pairs of gloves.

Step-by-step explanation:

Here we have to form two equations from the given information.

Let "x" be the number of pair of socks and "y" be the number of pair of gloves.

Given:

It takes flora 3 hours to knit a pair of socks and 7 hours to knit a pair of gloves. If she spent 65 hours knitting a total of 15 pairs of socks and gloves,

x + y = 15

3x + 7y = 65

Now we have to solve these two equations to find the solution.

Let's use the substitution method.

From the first equation can be written as

x = 15 - y

Now plug in x = 15 - y in the second equation and find the value of y.

3(15 - y) + 7y = 65 (This is called substitution method)

45 - 3y + 7y = 65

Simplify the like terms

45 + 4y = 65

Subtract 45 from both sides, we get

4y = 65 - 45

4y = 20

Dividing both sides by 4, we get

y = 20/4

y = 5

Now plug in y = 5 in the x = 15 - y

x = 15 - 5

x = 10

Therefore, Flora can make 10 pairs of socks and 5 pairs of gloves.
