Write an expression for the perimeter of the triangle shown below:
A triangle is shown with side lengths labeled 2.3x plus 14, 2x, and negative 0.2x plus 15.
4.1x + 29
4.1x − 29
4.5x + 29
4.5x − 29
Answer:
4.1x + 29
Step-by-step explanation:
1. Combine like terms (2.3x + 2x= 4.3x - 0.2x = 4.1x)
2. add the 14 + 15 = 2
That gives you the equation 4.1x + 29

1. The school office is now selling neon mechanical pencils. If the office pays $10.80 for a dozen pencils, how much should be charged to make a profit of 75 cents each?
2. Several cases of 16-ounce bottles of water were purchased for $252.00. If one case costs $7.00, how many cases were purchased?
3. Okolona College ordered jerseys to sell at the homecoming game. The college paid $9.25 each for 225 jerseys. Each jersey was sold for $15.75. What was the percent of markup for each jersey? How much profit was made if all of the jerseys were sold?
4. A truck traveled 654 miles on a long distance run. If the truck averaged 55 mph, how many hours did it take to reach the truck's destination? (Round to the nearest hour)
5. Della Riley borrowed $2400 for 6 months to invest in a business venture. If she agreed to pay 8% interest annually, how much will she be repaying?
6. It takes Dan an average of 45 minutes each evening to do his chemistry homework. Dan calculates that he worked a total of 3 hours on chemistry last week. Assuming that Dan worked his average time per evening consistently, how many evenings did Dan work?
7. Jon's car averages 20 mpg in town and 28 mpg on the road. What is the percent of decrease between the two driving conditions?
Answer:
1. Each pencil cost .90 cents each. So if they want to make a profit of 75 cents each they will get $9 for a dozen pencils. They must charge 75 cents.
2. Several means 4 but in this case, it means 36. When you divide 252 by 7 you get 36. Because each case is $7 and the total is 252.
3. The percent markup for each jersey was around 65%. They almost doubled the price by 6.50. They would make $3543.75 if they sold all the jerseys at the homecoming game.
4. The truck took 12 hours to reach its destination.
5. She would be repaying $ 1,152.00 in one year.

Malik collects rare stamps and has a total of 96 stamps. He has 24 more domestic stamps than foreign stamps. Let d represent the number of domestic stamps and let f represent the number of foreign stamps.
This system of equations models the given information for both stamp types.
d – f = 24
d + f = 96
Solve the system of equations.
How many foreign stamps does Malik have?
number of foreign stamps
How many domestic stamps does Malik have?
number of domestic stamps
Answer:
Domestic Stamps: 60
Foreign Stamps: 36
Step-by-step explanation:
96 - 24 = 72
72 ÷ 2 = 36
36 + 24 = 60
d - f = 24
60 - 36 = 24
24 = 24
d + f = 96
60 + 36 = 96
96 = 96
The circumference of a circle is 11pi inches, What is the area in inches of the circle express in terms of pi. Round to the nearest thousandths. 3.14
can someone help me out? (serious answers only)
Answer:
A.
Step-by-step explanation:
the diameter is 1.8 in.
diameter to circumference is multiplying the diameter by pi
1.8*= about 5.66 (Rounded to the nearest hundredth)
the 5.66 in. is going around 15 times
multiply 5.66 and 15
5.66*15=84.9

Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in miles per hour did each person run? Who ran the fastest? !!SHOW WORK!!
Answer:
Step-by-step explanation:
To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest
The graph shows the relationship between the number of gallons of fuel remaining in the tank of a semitruck and the number of miles traveled by the semitruck.
Which function can be used to find y, the number of gallons of fuel remaining in the tank of the semitruck after it has traveled x miles?
Answer:
the first person is wrong
Step-by-step explanation:
the answer is -1/10x+240
The function can be used to find y, the number of gallons of fuel remaining in the tank of the semi-truck after it has traveled x miles is -1/10x + 240.
What is the equation of a straight line?The equation of a straight line can be represented by:
y = mx + c
Where m is the slope of the graph and c is the intercept on the y axis.
From the graph attached, the intercept on the y axis is 240,
therefore c = 240.
To find the slope, we use the equation:
m = change in y / change in x
m = (195 - 240) / (450 - 0)
m = -45/450
m = -1/10
by substituting the value of c and m in the equation gives:
y = mx + c
Therefore, the answer is -1/10x + 240.

The mean is
The median is
Answer:the mean is because all the numbers added up are 5228.17 and then you divide by 10 because there is 10 numbers meaning that your mean is $522.89 the median is 425
Step-by-step explanation:
Answer:
mean price - $522.88
median price - $427.50
Step-by-step explanation:
$271.83 + $279.90 + $310.52 + $364.17 + $410.51 + $445.53 + $604.25 + $696.18 + $872.75 + $973.14 = 5,228.78 / 10 = 522.88
$271.83, $279.90, $310.52, $364.17, $410.51, $445.53, $604.25, $696.18, $872.75, 973.14 - there are two in the middle so find the average of the two = 427.50.

Suppose you go out to eat with a friend and your bill was $25.67. The local sales tax rate is 7% and you want to leave a 20% tip for the waitress. Calculate the 20% tip of $25.67. [tip]
( I need the tip)
Answer:
Umm I'm not sure is it 25...
Step-by-step explanation:
Answer:
Tip= $5.13
Step-by-step explanation:
You can crossmultiply and use the "Is/Of x %/100" method
= X/$25.67 x 20%/100
Cross multiply:
25.67 x 20 = 513.4
Xx100= 100X
To solve for X from here, divide both answers by 100
513.4/100= 5.13
100X/ 100 = X
So...
$5.13 = X

Jordan is painting his kitchen. To get the color he wants, he mixes 2 parts red paint and 6 parts yellow paint.
If he needs 18 parts of yellow paint, how much red paint will he need?
The solution is 6 parts of red paints
The number of red paints for the color to paint the kitchen is given by the equation A = 6 parts of red paints
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of parts of red paint be represented as A
Now , the equation will be
The number of red paint parts for 6 parts of yellow = 2 parts of red paint
The number of parts of yellow paint = 3 x 6 parts
The number of parts of yellow paint = 18 parts of yellow paint
So ,
The number of parts of red paint for 18 parts of yellow paint A = 3 x number of red paint parts for 6 parts of yellow
Substituting the values in the equation , we get
The number of parts of red paint for 18 parts of yellow paint A = 3 x 2
The number of parts of red paint for 18 parts of yellow paint A = 6 parts
Therefore , the value of A is 6 parts
Hence , the number of parts of red paint is 6 parts
