Answer:

A. t=-2h+32

Step-by-step explanation:

I'm pretty sure it's A. If the temperature starts at 32 degrees at midnight, that is going to be it's own number, not joined with a variable. In contrast, the temperature drops 2 degrees every hour, so the variable h will have a 2 with it (2h). But because it drops, the 2h will actually be negative. The equation would be written like this...

t=-2h+32, which is answer A.

I hope you understood! Good luck on your assignment and have an awesome day C:

The coordinates of the vertices of a polygon are (−5, 1) , (−1, 3) , (2, 3) , (2, −2) , and (−3, −1) .

Using the distance formula $d=\sqrt{(x_2-x_1) +(y_2-y_1) }$ Then we assign the points letter for simplicity

$A= (-5.1),B=(-1,3),C=(2,3),D=(2,-2),E=(-3,-1)$ . The distance formula gives us the magnitude between two points hence,

$AB=\sqrt{(-5-(-1))^2+ (-1-3)^2}=\sqrt{16+16}= 5.65$

$BC=\sqrt{(-1-2)^2+(3-3)^2}= \sqrt{9}=3$

$CD=\sqrt{(2-2)^2+((3-(-2))^2} =\sqrt{25}=5$

$DE=\sqrt{(2-(-3))^2+(-2-(-1))^2} =\sqrt{26+1} =5.099$

$AE=\sqrt{(-3-(-5))^2+(-1-1)^2}= \sqrt{4+4} =\sqrt{8}=2.82$

$Perimeter= AB+BC+CD+DE+AE\\Perimeter=5.65+3+5+5.099+2.82=21.57 units$

A combo meal and a salad cost $12

lubasha [3.4K]

Answer:

The cost of a combo meal is $8 and a salad is $4.

Step-by-step explanation:

You have to form simultaneous equations with the given informations. Let combo meal be m and salad is s :

$m + s = 12 - - - (1)$

$2m + s = 20 - - - (2)$

Next, you have to solve these equations :

$(2) - (1)$

$2m + s - m - s = 20 - 12$

$m = 8$

$sub \: \: m = 8 \: \: into \: \: (1)$

$(1)⇒$

$8 + s = 12$

$s = 4$

Use the list method to write "The perfect square integers between 1 and 80 inclusive".

oksian1 [2.3K]

ANSWER

{1, 4, 9, 16, 25, 36, 49, 64}

EXPLANATION

The perfect square integers between 1 and 80 inclusive are obtained by squaring the natural numbers from 1 to 8

${1}^{2} = 1$

${2}^{2} = 4$

${3}^{2} = 9$

${4}^{2} = 16$

${5}^{2} = 25$

${6}^{2} = 36$

${7}^{2} = 49$

${8}^{2} = 64$

The square of the next number does not fall within the given range.

Therefore "The perfect square integers between 1 and 80 inclusive" are

{1, 4, 9, 16, 25, 36, 49, 64}
