1. 10 division comes first :)
2. 3 division comes first :)

3. 29 division, then multiplication comes first :)
4. 32 8 x 4 :)

5. $5.00 $10.00 - $5.00 :)

6. 870 48 x 8, then 54 x 9 :)
Glad I could help, and good luck :)

2- 38/9 = 4.2 ~ 4 - 3= 1
3- 56/7 = 8 + 7*3= 21 + 8= 29
4- 8*4= 32
5- 3+2= 5 then 10 - 5 = 5 bucks for his change
6- 48*8 = 384 and 54 *9 = 486. 486 + 384 = 870 seats in the arena.

An art museum has a pentagon-shaped room. When drawn to scale on a coordinate grid, the corners of the room are points (18,20):

AURORKA [14]

Answer:

$2\ gal$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$A(18,20),B(4,20),C(4,4),D(16.2),E(22.10)$

step 1

Find the distance AB

we have

$A(18,20),B(4,20)$

substitute in the formula

$d=\sqrt{(20-20)^{2}+(4-18)^{2}}$

$d=\sqrt{(0)^{2}+(-14)^{2}}$

$AB=14\ ft$

step 2

Find the distance BC

we have

$B(4,20),C(4,4)$

substitute in the formula

$d=\sqrt{(4-20)^{2}+(4-4)^{2}}$

$d=\sqrt{(-16)^{2}+(0)^{2}}$

$BC=16\ ft$

step 3

Find the distance DE

we have

$D(16.2),E(22.10)$

substitute in the formula

$d=\sqrt{(10-2)^{2}+(22-16)^{2}}$

$d=\sqrt{(8)^{2}+(6)^{2}}$

$d=\sqrt{100}$

$DE=10\ ft$

step 4

Find the distance AE

we have

$A(18,20),E(22.10)$

substitute in the formula

$d=\sqrt{(10-20)^{2}+(22-18)^{2}}$

$d=\sqrt{(-10)^{2}+(4)^{2}}$

$d=\sqrt{116}$

$AE=10.77\ ft$

step 5

Find out the area of the four walls

To determine the area sum the length sides and multiply by the height of the walls

$A=(AB+BC+DE+AE)h$

substitute the given values

The height of the walls is 10 ft

$A=(14+16+10+10.77)10$

$A=(50.77)10$

$A=507.7\ ft^2$

step 6

Determine the number of gallons needed to paint the four walls

we know that

one gallon of paint is enough to cover 400 square feet

using proportion

$\frac{1}{400}\ \frac{gal}{ft^2}=\frac{x}{507.7}\ \frac{gal}{ft^2}\\\\x=507.7/400\\\\x= 1.27\ gal$

Round up

$x=2\ gal$

Ava, Kate, and Jin bring all the food to a picnic. Ava brings 34, Kate brings 16, and Jin brings 112. Enter a numerical expressi

juin [17]

Answer:

Step-by-step explanation:

Given that:

Ava bring 34 food to the picnic

Kate bring 16 food to the picnic

JIn brings 112 food to the picnic

To enter these digits by applying equivalent fractions with a denominator of 12;

Their respective numerical expression is:

Ava = $\dfrac{34}{12}$

Ava brought $2 \dfrac{5}{6}$ food to the picnic

Kate = $\dfrac{16}{12}$

Kate brought $1 \dfrac{1}{3}$ food to the picnic

Jin = $\dfrac{112}{12}$

Jin brought $9 \dfrac{1}{3}$ food to the picnic

Which method and additional information would prove triangle ONP and triangle MNL similar by the AA similarity postulate?

MA_775_DIABLO [31]

<h3>Answer: Choice B</h3>

Use a rigid transformation to prove that angle NPO is congruent to angle NLM

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

Explanation:

The AA stands for "angle angle". So we need two pairs of angles to prove the triangles to be similar. The first pair of angles is the vertical angles ONP and MNL, which are congruent. Any pair of vertical angles are always congruent.

The second pair of angles could either be

angle NOP = angle NML
angle NPO = angle NLM

so we have a choice on which to pick. The pairing angle NOP = angle NML is not listed in the answer choices, but angle NPO = angle NLM is listed as choice B.

Saying angle NLM = angle LMN is not useful because those two angles are part of the same triangle. The two angles must be in separate triangles to be able to tie the triangles together.

We would use a rigid transformation to have angle NPO move to angle NLM, or vice versa through the use of a rotation and a translation.
