Mia rode 3 miles in a taxi. What was the total cost ,in dollars,of her ride the ride costs 2.50 a mile
Answer:
Total cost = $7.5
Step-by-step explanation:
Given the following data;
Total distance = 3 miles
Cost per distance = $2.50
To find the total cost ofof ride, we would use the following mathematical expression;
Total cost = total distance * cost per distance
Total cost = 3 * 2.5
Total cost = $7.5
Therefore, the total cost, in dollars, of Mia's ride is 7.5.

QUIZ 3: ORGANIZING SPEECHES
Pls answer this I will give 10 points and brainlest for 4 to 6 answers
Answer:
I suppose we are using the given measurements.
Step-by-step explanation:
So my best guess would be, PD = 18, BP= 30, FP = 19.5 (because that's half of 39 and it's basically the same length as BF). PA = 30, and CD = 39(?)

A store pays $147 for a skateboard. If the store marks it up 75%, then marks it down 22%. What is the new cost
Answer:
$200.65
Step-by-step explanation:
If they bought it for 147 then marked it up 75% you would do
$147+75% = 257.25
THEN they mark down
257.25 - 22% = $200.255 which would be
$200.25 orrr $200.26
I need so much help ☹️
Answer:
666mm
Step-by-step explanation:
A= 1/2 Base x Height . For triangle
A= 1/2 (10)(12)
A=1/2 (120)
A=60 . One triangle is 60, so 2 triangles are 120 mm
Rectangle
A= BxH
A=(14)(13)
A=182mm But since there are 3 triangles you multiply 182 times 3
(182x3)+120
=666
Area of the figure is 666mm
if x degree and 115 degree are co exterior angles find the vaule of x degree
Answer:
65 degrees
Step-by-step explanation:
An exterior angle form a linear pair with an interior angle.
A linear pair of angles must add up to 180 degrees
180-115 = 65
CAN SOMEONE HELP ME PLEASE IM SO FRUSTRATED BECAUSE NO ONE IS HELPING ME PLS JUST BE NICE AND HELP ME PLS :’) NO LINKS NO BOTS OR JUST ANSWERS TO GET POINTS I WILL REPORT !!!Which of the following equations describes the line shown below? Check all
that apply.
(12,6) (4,4)
Answer:
I'm sorry that no one is helping you, the correct answers are A and F.
Step-by-step explanation:
The line's equation is [tex]y=\frac{1}{4} +3[/tex]. You know this because the slope of the line is found by subtracting the y-value of the two points and dividing it by the difference of the x-values, which would be [tex]\frac{6-4}{12-4} = \frac{2}{8} = \frac{1}{4}[/tex]. Using the slope, you can calculate the y-intercept of the equation, which you just multiply the slope by the distance to the y-axis and subtract that from the y-value of (4, 4), which you will get [tex]4 + (-4*\frac{1}{4}) = 4+(-1) = 3[/tex]. So the equation of the line is [tex]y=\frac{1}{4} +3[/tex]. When you simplify all the choices below, you'll get that only A and F are equivalent to the equation, so those are the correct choices.

Step-by-step explanation:
Micheal home is 12 feet below and his mother's home is 12 above sea level
Micheal says their homes are elevations because they are in opposite directions Is he correct? Explain.
Answer:
Yes, Michael is correct. The elevation is measured in terms of sea level. Because Michael's home is 12 feet below sea level and his mother's home being 12 feet above sea level, their homes are at equally opposite directions.

You 5-year loan of $14,000 is at 4.3% compounded annually. How much will you have paid in total for your loan?
Answer:
$17,276
Step-by-step explanation:
Given data
Time= 5 years
Principal= $14,000
Rate= 4.3%
We want to find the final amount
A=P(1+r)^t
Substitute
A= 14000(1+0.043)^5
A= 14000(1.043)^5
A= 14000*1.234
A=$17276
Hence the total amount is $17,276

Enter the median, lower quartile, and upper quartile of the scores of 11 students on the geography quiz.
82, 75, 93, 73, 71, 95, 89, 84, 72, 79, 84
Answer:
Median - 15.5
Lower Quartile - 13
Upper Quartile - 22.5
Steps to calculate Median:
1. Orchestrate your numbers in mathematical request.
2. Check the number of numbers you have.
3. On the off chance that you have an odd number, partition by 2 and gather together to get the situation of the middle number.
4. On the off chance that you have a considerably number, partition by 2. Go to the number around there and normal it with the number in the following higher situation to get the middle.
Steps to calculate Upper and Lower Quartile:
1. Request your informational index from most minimal to most elevated qualities.
2. Track down the middle. This is the second quartile Q2.
3. At Q2 split the arranged informational collection into equal parts.
4. The lower quartile Q1 is the middle of the lower half of the information.
5. The upper quartile Q3 is the middle of the upper portion of the information.
The population of a town is 75 000 and decreases 15% each year. Complete the exponential function that models the population afterx years
f(x) = 75,000
Answer:
Step-by-step explanation:
This is an exponential function of the form:
[tex]y=a(1-r)^x[/tex] where a is the initial value and (1 - r) is the growth rate (which in our case is a decay, actually!). Our initial value is 75000 and our rate of change in the population is 15% or .15. Filling in our model:
[tex]y=75000(1-.15)^x[/tex] and simplifying:
[tex]y=75000(.85)^x[/tex] This turns out to be a decay problem because the value inside the parenthesis is less than 100%.
x is our time, so the model is as stated above.
The radius of a cylindrical construction pipe is 2 ft. If the pipe is 17 ft long, what is its volume?
Use the value 3.14 for it, and round your answer to the nearest whole number.
Answer:
[tex]volume \: = \: \pi \times r {}^{2} \times length(height) \\ = 3.14 \times 2f \times 17ft \\ = 106.76ft {}^{3} [/tex]
Answer:
V = 106.76ft
