Step-by-step explanation:

AB BC AC

(I’m not sure, If Im wrong let me knoww ❤️❤️)

Answer:

AC BA BC shortest to longest.

Step-by-step explanation:

All triangles have 180o in their interior angles. So A + B + C = 180

5x - 4 + 2x + 3 + 3x - 9 = 180      Combine the like terms on the left.

10x - 10 = 180                               Add 10 to both sides

10x - 10 + 10 = 180 + 10

10x = 190

x = 190/10

x = 19

So <A = 5x - 4 = 91

<B = 2x + 3 = 41

<C = 3x - 9 = 48

Total             180

So the largest Line is opposite 91 and it is BC

The Middle sides line is opposite 48 and it is BA

The smallest line is  opposite 41 and it is AC

AC BA BC shortest to longest.

I'm not sure what AAS,SAS,SSS,ASA mean .how do I solve this?​

Answers

Answer:

AAS is an acronym for Angle-Angle-Side. It basically means that if two angles and a nonincluded side of one triangle are congruent to two  angles and the corresponding nonincluded side of a second triangle, then  the two triangles are congruent. SAS is an acronym for Side-Angle-Side. It means that if two sides and the included angle of one triangle are congruent to two  sides and the included angle of a second triangle, then the two triangles  are congruent. SSS is an acronym for Side-Side-Side. It means that if three sides of one triangle are congruent to three sides of a second  triangle, then the two triangles are congruent. ASA is an acronym for Angle-Side-Angle. It means that if two angles and the included side of one triangle are congruent to two  angles and the included side of a second triangle, then the two triangles  are congruent.

In the problem, we know that the corresponding sides of both triangles are congruent to each other, so those would be given. The third side of each triangle would also be congruent because of reflexive property. Reflexive property means that the two triangles share a line segment. So, the answer would be SSS.

Convert -4x+y=5 to slop intercept form​

Answers

Answer: -4x + y = 5 in slope intercept form is 4x + 5

Answer: y= 4x + 5

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y = mx + b

Rewrite in slope-intercept form.

Add 4x to both sides of the equation.

y = 5 + 4x

Reorder 5 and 4x.

y= 4x + 5

Emily Elizabeth has $1.50 in dimes and nickels. She has 22 coins in all. How many nickels does she have?

Answers

Answer:

[tex]14[/tex]

Step-by-step explanation:

We can set up the following system of equations:

[tex]\begin{cases}10d+5n=150\\d+n=22\\\end{cases}[/tex], where [tex]d[/tex] is the number of dimes she has and [tex]n[/tex] is the number of nickels she has.

Multiplying the second equation by -5 and adding both equations lets us isolate and solve for [tex]d[/tex]:

[tex]10d+5n+(-5(d+n))=150+(-5(22)),\\5d=40,\\d=8[/tex]

Plugging [tex]d=8[/tex] into any of the two equations will let us solve for [tex]n[/tex]:

[tex]8+n=22,\\n=\fbox{$14$}[/tex].

Therefore, she has 14 nickels.

Noah already has $10.50, and he earns $3 each time he runs an errand for his neighbor. Noah wants to know how many errands he needs to run to have at least $30

Answers

Answer: 7 errands

Step-by-step explanation:

Noah wants to have at least $30. He however already has $10.50.

The amount that he needs is:

= 30 - 10.50

= $19.30

For every errand he runs, he makes $3. The number of errands needed to get to $30 is:

= 19.50/3

= 6.5

= 7 errands

A baseball team batted 250 times during the season. During the season they got 120 hits, 60 strikeouts, 50 flyouts and 20 groundouts. What percent of the time that they batted did they make an out?

Answers

Answer: 52%

Step-by-step explanation:

The team batted 250 times. In that time, they got 60 strikeouts, 50 flyouts and 20 groundouts.

The total number of out they got was therefore:

= 60 + 50 + 20

= 130 outs

The percent of the time they got outs out of the total is:

= 130/250

= 52%

6338 divided by 43 with remainder

Answers

Answer:

147.395348837

Step-by-step explanation:

6338 divided by 43 gives a quotient of 147 with a remainder of 17.

When dividing 6338 by 43 with remainder, we can perform long division to find the quotient and remainder.

Start by dividing the first digit of the dividend (6) by the divisor (43). The quotient is 0 since 6 is less than 43.

Bring down the next digit of the dividend, which is 3, to the right of the 0. We now have 63.

Divide 63 by 43. The quotient is 1, as 43 goes into 63 once.

Multiply the divisor (43) by the quotient (1) and subtract the result from 63:

63 - (43 x 1) = 63 - 43 = 20

Bring down the next digit of the dividend, which is 3, to the right of the 20. We now have 203.

Divide 203 by 43. The quotient is 4, as 43 goes into 203 four times.

The final remainder is 17.

Therefore, 6338 divided by 43 gives a quotient of 147 with a remainder of 17.

Eli is deciding between two landscaping companies for his place of business. Company A charges $25 per hour and a $300 equipment fee. Company B charges $50 per hour and a $125 equipment fee. Let AA represent the amount Company A would charge for tt hours of landscaping, and let BB represent the amount Company B would charge for tt hours of landscaping. Write an equation for each situation, in terms of t,t, and determine which company would be cheaper if Eli needs 5 hours of landscaping.

Answers

Answer:

Company B will charge cheaper in 5 hours

Step-by-step explanation:

Step one:

Given data

Company A

charges $25 per hour and a $300 equipment fee

let the total be

A= 300+25t---------------1

Company B

charges $50 per hour and a $125 equipment fee.

let the total be

A= 125+50t---------------2

put t = 5 in the two expressions above

A= 300+25t---------------1

A= 300+25*5

A=300+125

A=$425

B= 125+50t---------------2

B= 125+50*5

B=125+250

B=$375

Answer:

A = 25t + 300 B = 50t + 125

company B is $50 cheaper than company A for 5 hours of landscaping

Answer:

1) Actual cost was $5,762.50

2) Joe's birthday is on January 1st.

Step-by-step explanation:

1) To find this, since we know they were wrong by an identical amount and one was over and the other was under, we can average the cost to find the difference between the amounts. Then we can add that difference to the lower (or subtract it from the higher) amount:

6950 - 4575 = 2375

2375 / 2 = 1187.50

4575 + 1187.50 = $5,762.50

2) Joe could turn 21 on January 1st, but was 20 on December 31st. Next year Joe would turn 22 on January 1st.

The perimeter of a rectangle is 28 inches. The length is 6 less than 3 times the width. What is the length of the rectangle?

Answers

Answer: The length is 9 inches.

Step-by-step explanation:

L = 3w - 6 (the length is 6 less than 3 times the width).28 = 2(3w - 6) + 2w (plug in width and length --> multiplied by 2 because of perimeter).28 = 6w - 12 + 2w (distribute)28 = 8w - 12 (combine like terms)40 = 8w (add 12 to both sides)5 = w <-- width

Find the length:

L = 3w - 6L = 3(5) - 6L = 15 -6L = 9 in

The length is 9.
