Z corresponds to D

W corresponds to A and

X correspondents to B

rotate it in your mind

from D to C gives you a good clue where to place Y.

4,-5 is correct

In a triangle , the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 80 mo

Flauer [41]

Answer:

25, 50, and 105.

Step-by-step explanation:

Let the first angle be A, the second angle be B, and the third angle be C.

First, the sum of the three angles in a triangle is 180. Thus:

$A+B+C=180$

We know that the measure of A is twice the measure of B. Thus:

$A=2B$

And the measure of C is 80 more than the measure of B. So:

$C=80+B$

Let's substitute A and C into the original equation:

$2B+B+80+B=180$

Now, let's solve for the second angle (B). Combine like terms:

$4B+80=180$

Subtract 80 from both sides:

$4B=100$

Divide both sides by 4:

$B=25$

So, the second angle is 25 degrees.

This means that the first angle is 2(25) or 50 degrees.

And the third angle is 80+25 or 105 degrees.

And we're done!

The angles are 25, 50, and 105.

HELP ME PLEASEEEE! Thank you

Sergio039 [100]

Answer:

A. Yes

B. Yes

C. No

Step-by-step explanation:

We can substitute each value in to the equation and see if the sides match up. Let's start with a.

$4\cdot(2)-3 = -2\cdot(2)+9\\8-3 = -4+9\\5 = 5$

So, n = 2 works for equation a. Let's try B.

$9\cdot(\frac{10}{3}) - 19 = 3\cdot(\frac{10}{3}) + 1\\\\\\\frac{90}{3} -19 = \frac{30}{3} + 1 \\ 30 - 19 = 10 + 1\\11 = 11$

So, m = $\frac{10}{3}$ works for B. Now let's try C.

$3(30+8) = 2\cdot(30)-6\\3(38) = 60-6\\114 \neq 54$

So y = 30 doesn't work for C.

Hope this helped!

Students are planning a hotdog sale. They expect to sell about 250 hotdogs. The local grocery store sells wieners in packages of

Arlecino [84]

Answer:

The wieners come in packages of 12 and the buns in packages of 8. Then we must find the common multiple of 8 and 12 that is closest to 100 (because the want to make about 100 hotdogs)

then the multiples of 12 are next to 100 are:

12*10 = 120

12*9 = 111

12*8 = 99

and the ones for 8 are:

we already know that 8*12 = 99, so we try with 13:

8*13 = 104

then they need to buy 9 packages of wieners and 13 packages of buns, the number of hotdogs that they can make is equal to 104, and with a:

111 - 104 = 7 wieners leftovers

Determine whether or not it is a function

Brrunno [24]

This is indeed a function because every domain is only used once, a domain can indeed share a range but can’t be the same for which it’s a function due to the fact that no domain is repeated with a different outcome
