Answer:
-23
Step-by-step explanation:
When you do positive-negative you subtract the 2 numbers then take the sign of the number that had the highest absolute value.
25-2=23
The absolute value of -25 is 25
(|-25| = 25)
And the absolute value of 2 is 2
(|2| = 2)
25 > 2
So it would be -23

Volume of a rectangular prism: 729m
3. Volume of a cylinder: 285 cm: Volume of a cone:
4. Volume of a sphere:
Volume of a cylinder: 600cm
5. Volume of a cone: 50 m: Volume of a cylinder:
Answer:
576 FT^3
243 m^3
95 cm^3
400 cm^3
150 m^3
Step-by-step explanation:
Volume of a pyramid = 1/3 x ( length base x height)
Volume of a prism= ( length base x height)
1. prism = 192 x 3 = 576 FT^3
2. prism = 729 / 3 = 243 ft^3
volume of a cylinder = nr^2h
Volume of a cone = 1/3(nr^2h)
3. cone = 285/3 = 95
5. cylinder = 50 x 3 = 150
4. sphere = 600 / 1.5 = 400
Dada a função fx=0,15.X+900 , determine a) f(80) b) f(120) c) f(200) d) f(56)
Answer:
See answers below
Step-by-step explanation:
Given the function:
f(x) = 0.15x + 900
a) f(80) = 0.15(80) + 900
f(80) = 12 + 900
f(80) = 912
b) f(120) = 0.15(120) + 900
f(120) = 18 + 900
f(120) = 918
c) f(200) = 0.15(200) + 900
f(200) = 30 + 900
f(200) = 930
d) f(56) = 0.15(56) + 900
f(56) = 8.4 + 900
f(56) = 908.4

in a group of 120 students,90 students study mathematics and 72 study science. if 10 of the student does not study any subject
1)find the no.of students who study atleast 1 subject
2)number of students studying both subjects
3)how many students will study mathematics only?
4)how many students will study science only?
Answer:
Step-by-step explanation:
Total students = 120
Number of students studying Mathematics P(A) = 90
Number of students studying Science P(B) = 72
Number of students who doesn't study both subjects P(AUB)'= 10
1) Number of students studying atleast on subject = 120 -10 = 110
2) Number of students studying both math and science = (90 +72) -110
= 162 -110 = 52
3) Number of students studying only mathematics = 90 -52 = 38
4) Number of students studying only science = 72 -52 = 20

Answers:
Perimeter = 22 cmPerimeter = 22 cmPerimeter = 30 cm==============================================
Explanation:
The perimeter is the total distance around the outer edge of the figure. It's the total amount of fence you need to enclose the region.
So we simply add up all the side lengths. Refer to the diagram to see any missing sides that aren't labeled (shown in blue).
For instance, the perimeter for problem 1 is 5+2+2.5+4+2.5+6 = 22 cm. Problems 2 and 3 are handled the same way.
It's not a typo that the perimeters of problems 1 and 2 are the same value. This is because both figures can be surrounded by a rectangle that is 6 cm across and 5 cm tall. The perimeter of the surrounding rectangle is exactly the same as the perimeter of the inner fenced region. We're effectively just moving fence around but not changing the perimeter.

What is the slope of the line passing through the points (-5, -4) and (-1, 6)?
Step-by-step explanation:
using the formula (y2-y1)/(x2-x1)we plug the numbers In the slop formula (6--4)/(-1--5)= 10/4
Answer:
Step-by-step explanation:
(x1,y1)= (-5,-4)
(x2,y2)=(-1,6)
Distance=√(x2-x1)²+(y2-y1)²
=(-1-5)²+(6-4)²
=(-6)²+(10)²
=36+100
=136 answer,,
therefore, the slope of the line is 136unit

The amounts that two plumbers charge for their services are described.
The first plumber charges a fixed fee of $40 for house calls and $15 per hour of work.
The second plumber charges a fixed fee of $30 for house calls and $19 per hour of work.
For what number of hours work do the first plumber and the second plumber charge the same total amount?
Answer:
See below.
Step-by-step explanation:
40 + 15x = 30 + 19x
15x - 19x = 30 - 40
-4x = -10
x = 2.5
Two and a half hours.
The first plumber and the second plumber charge the same total amount for 2.5 hours of work.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The number of hours worked by both plumbers is "h". Then the total amount charged by the first plumber is:
Total cost for the first plumber = 40 + 15h
And, the total amount charged by the second plumber is:
Total cost for the second plumber = 30 + 19h
To find the number of hours for which both plumbers charge the same total amount, we need to solve the equation:
40 + 15h = 30 + 19h
4h = 10
h = 2.5
Therefore, the first plumber and the second plumber charge the same total amount for 2.5 hours of work.

Jacqui likes to travel to the beach on weekends. She starts at her house, drives d miles, and then spends t hours walking the remaining w miles to get to the beach. Jacqui drives three times as long as she walks during the trip. The equation below represents Jacqui's average speed, a, in miles per hour, when traveling to the beach. a=d+w/3t+t What is the meaning of 3t + t3t+t in the equation above? -The total time that Jacqui spends traveling to the beach -The time that Jacqui spends driving to the beach -The total distance that Jacqui travels to the beach -Jacqui's maximum speed during her trip Jacqui's average speed during one trip to the beach was 3636 miles per hour. If Jacqui drove 70 miles and the entire trip to the beach took her 22 hours, how many miles did she walk to get to the beach?
Answer:
The answer is below
Step-by-step explanation:
1) Average speed is the ratio of the total distance travelled to the total time taken. Hence it is given by:
Average speed = total distance / total time
Total distance = d miles + w miles
Jacqui drives three times as long as she walks during the trip, hence:
time spent driving = 3t
Total time = 3t + t
Average speed = total distance / total time
a = (d + w) / (3t + t)
2) (3t + t) represents the total time that Jacqui spends traveling to the beach.
3) Given that a = 36 miles per hour, total time = 2 hours
a = total distance / total time
36 miles per hour = total distance / 2 hours
total distance = 72 miles
Total distance = distance walk + distance drove
72 = distance walk + 70
Distance walk = 2 miles

The a to the left of the parentheses multiplies both numbers inside the parentheses. The you add the products.
This is the distributive property of multiplication over addition.

Answer:
604.4 cm²
Step-by-step explanation:
Surface area of a cone = πr(r + √h² + r²)
π = 3.14
r = diameter/2 = 13.4 cm/2 = 6.7 cm
h = 21 cm
Surface area of a cone = πr(r + √h² + r²)
= 3.14 * 6.7(6.7 + √21² + 6.7²)
= 21.038(6.7 + √441 + 44.89)
= 21.038(6.7 + √485.89)
= 21.038(6.7 + 22.04)
= 21.028(28.74)
= 604.3 cm²
Surface area of a cone = 604.4 cm²

Please help me please I will really appreciate
Answer:
Step-by-step explanation:
If we draw this triangle with Q as the vertex angle (the one at the top of the triangle) then the 2 sides are congruent and this is an iosceles triangle. Because this is an isosceles triangle, then the 2 base angles, angle R and angle S are congruent. If Q measures 114 degrees, then angles R and S together have to add up to the difference between 180 and 114:
180 - 114 = 66
Divide that in half so R = S = 33 degrees each
