Answer: 10 minutes
Step-by-step explanation:
x·1/20 + x·1/25 + x·1/100 = 1
Multiply each term by 100 to clear the equation of all fractions
100x/20 + 100x/25 + 100x/100 = 100
5x + 4x + 1x = 100
10x = 100
x = 10
The answer is 10 minutes

Answer:
[tex] \bf \huge2[/tex]
Step-by-step explanation:
Given :11v + -15v = 8to find :solve for vexplanation :step 1 : Simplify both sides of the equation.
⟼ 11v + -15v = 8
⟼ 11v - 15v = 8
⟼ - 4v = 8
step 2 : Divide both sides by - 4.
⟼ - 4v / - 4 = 8 / - 4
⟼ v = - 1 × - 2
⟼ v = - 2.
∴ v = 2.

Answer:
X=8
z=80
Step-by-step explanation:
Okay to find X you gotta find the other angle.
The other angle is 100 which is also vertical To (6x+52)
Vertical angles are equal or congruent so you cna make an eqaution to equal it
6x+52=100
Solve it like a normal equation
x=8
To find Z you gotta realize that 4 angles equal 360 degrees.
We knwo the two vertical angles, 100 and 100. Z is vertical to no name angle so its equal so it can also be Z. Z+Z=2z
Now If you add em all up you should get 360
2z+100+100=360
2z+200=360
Solve from here
z=80
Given the diagram below, what is mD?
Answer:
A
Step-by-step explanation:
Answer:
A. 72
Step-by-step explanation:
There are two ways to solve this problem. First of all, this quadrilateral is a trapezoid because the top two angles are congruent and there is one pair of parallel lines. One way to solve the problem is to remember all trapezoids have a measure of 360. So, mD=360-(108+108+72); this equals 72. Additionally, in a trapezoid, the bottom two angles are always congruent; therefore, angle D must equal 72 degrees.

Whats the area of number 10 ? Help please, help me do it and explain if you can! BTW THIS IS COMPOSITE SHAPES
Answer:
10. Area = 72 units²
Step-by-step explanation:
10. The shape in number 10 is a trapezoid.
Area of trapezoid = ½(a + b)*h
Where,
a = 6
b = 12
h = 8
Area = ½(6 + 12) * 8
Area = ½(18)8
Area = 72 units²
What is the volume of a hemisphere with a radius of 3.1 in, rounded to the nearest tenth of a cubic inch?
The volume of a hemisphere with a radius of 3.1 in. is 62.39 cubic inch
What is a hemisphere?The Hemisphere is the half part of a sphere.
What is the volume of a hemisphere?The volume of a hemisphere = (2/3)πr³ cubic units where r is the radius
Given radius is 3.1 in.
volume = (2/3)π(3.1)³
=62.39 cubic inch
Thus the volume of a hemisphere with a radius of 3.1 in. is 62.39 cubic inch

Could x = - 5 be a solution to the inequality
-6 < 3x + 9 < 21?
Step-by-step explanation:
[tex]3x + 9 = 3( - 5) + 9 \\ = - 15 + 9 \\ = - 6[/tex]
3x+9 is equals to -6 , not more than based on the inequality, but it is lesser than 21.
However, the solution must fulfil both criteria to be a solution to the inequality. Therefore x = -5 is not a solution to the inequality.

2. 21
3. 63
Step-by-step explanation:
Hope this helps have a nice day!
Answer:
1) 42
2) 21
3) 63
Step-by-step explanation:
1)
50% = 0.5
84(0.5) = 42
2)
25% = 0.25
84(0.25) = 21
3)
75% = 0.75
84(0.75) = 63
A normal six sided die is thrown once the number of outcomes in the sample is
Answer:
1/6
Step-by-step explanation:
Since it's a six sided die there's 6 different sides the die could land on the probability of landing on certain number depends on how much you roll the die.
For example: you roll the die 10 times and you land on 3, 5 times. the probability landing on 3 was 5/10 or 50%
Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(2, - 6) * B * (5, - 6), C(5, - 2) and D(2, - 2) . What the perimeter of rectangle ABCD
Answer:
14 units.
Step-by-step explanation:
Graph all the points on a coordinate grid. Two sides are 4 units each and the other two sides are 3 unites each.
P = 2(l + w)
P = 2(3 + 4)
P = 6 + 8 ← (The distributive property) OR 2(7) ← (Normal way to solve)
P = 14 units and 14 units.
You could also do addition.
P = 3 + 3 + 4 + 4
P = 6 + 8
P = 14 units

C. 35.3 km
D. 21.9 km
9514 1404 393
Answer:
C. 35.3 km
Step-by-step explanation:
From your knowledge of right triangles, you know that the hypotenuse is longer than the longest leg and shorter than the sum of the legs.
For this geometry, the distance of interest is longer than 32 km and shorter than 15+32 = 47 km. The only answer choice in the correct range is ...
35.3 km

8≤n
Thats basically it
Answer:
n ≥ 8
Step-by-step explanation:
We want to isolate n to solve the inequality. To do that, you add 4 to both sides, so 4 + 4 = 8 on the left and n - 4 + 4 = n on the right. That leaves you with 8 ≤ n, or n ≥ 8.
