One of the legs of a right triangle measures 11 cm and its hypotenuse measures 12 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
4.8cm
Step-by-step explanation:
a²+b²=c² where c is the hypotenuse so
Let's plug in those values
11²+b²=12²
b²=12²-11²
b²=23
b=4.8

• How do you write the mixed number shown as a fraction greater than l? 3 4
Answer:
[tex] \frac{14}{4} [/tex]
simplified [tex] \frac{7}{2} [/tex]
Step-by-step explanation:
To turn a mixed number into a fraction :
[tex]3\frac{ + 2}{ \times 4} [/tex]
3 x 4 =12 +2 =14 that will be your numerator (top number on a fraction)
and 4 will be your demoninator (bottom number)
Suppose a video store charges non-members $10 to rent each video. However, a membership costs $21 and members pay $3 to rent each video. For what number of videos is the cost the same?
Answer:
3
Step-by-step explanation:
Non Members pay $10 dollars each video 3 x 10= $30
membership costs $21 + 3 videos $3 each $21 + $9 =$30
Price is the same after 3 videos rented
A house was sold for $60,000 ten years ago. It has increase in value 55%. What is the value of the house now?
Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $8 monthly fee and charges an additional $0.12 for each minute of calls. The second plan has a $18 monthly fee and charges an additional $0.7 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?
Answer:
200 minutes
Step-by-step explanation:
Let us assume the number of minutes be x
Now the two equations are
$8 + 0.12x = 0
And, $18 + 0.7x = 0
In the case when the cost of the two plans is equal
So
$8 + 0.12x = $18 + 0.7x
$8 - $18 = 0.7x - 0.12x
-$10 = -0.05x
x = 200 minutes
Question 4 (1 point) The half life of Cs-137 is 30.2 years. If the initial mass of the sample is 100kg, how much will remain after 151 years? Leave your answer as a decimal and do not round, Answer = kg Blank 1:
Answer:
3.12 kg.
Step-by-step explanation:
Mass after t years:
The mass of the elements after t years is given by the following equation:
[tex]M(t) = M(0)(1-r)^t[/tex]
In which M(0) is the initial mass and r is the decay rate, as a decimal.
The half life of Cs-137 is 30.2 years.
This means that:
[tex]M(30.2) = 0.5M(0)[/tex]
We use this to find r.
[tex]M(t) = M(0)(1-r)^t[/tex]
[tex]0.5 = M(0)(1-r)^{30.2}[/tex]
[tex](1-r)^{30.2} = 0.5[/tex]
[tex]\sqrt[30.2]{(1-r)^{30.2}} = \sqrt[30.2]{0.5}[/tex]
[tex]1 - r = 0.5^{\frac{1}{30.2}}[/tex]
[tex]1 - r = 0.9773[/tex]
So
[tex]M(t) = M(0)(0.9773)^{t}[/tex]
If the initial mass of the sample is 100kg, how much will remain after 151 years?
This is M(151), with M(0) = 100. So
[tex]M(t) = 100(0.9773)^{t}[/tex]
[tex]M(151) = 100(0.9773)^{151} = 3.12[/tex]
The answer is 3.12 kg.

Answer:
c
Step-by-step explanation:
Answer:
No solutions
Step-by-step explanation:
If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. ... When the lines are parallel, there are no solutions, and sometimes the two equations will graph as the same line, in which case we have an infinite number of solutions.

Step-by-step explanation:
18 girls and 12 boys on a swim team. what is the percentage of boys?
Answer:
40%
Step-by-step explanation:
The first step is to add 18 girls + 12 boys, which gives you the total number of people on the swim team, 30.
Next, you divide the 12 boys by the total swim team members, so:
[tex]\frac{12}{30}[/tex] = 0.4
Then, you multiply 0.4 by 100 to get the percentage:
0.4 × 100 = 40
Therefore, the swim team is made up of 40% boys, and 60% girls.
Answer:
40%
Step-by-step explanation:
30 total kids
12/30 as a decimal is 0.4
to make a decimal into a percent you move the decimal point 2 times to the right
that would be 40
then add the percent to make 40%

Answer/Step-by-step explanation:
✔️Diagonals of a rhombus bisect each other at 90°.
Therefore,
m<1 = 90°
✔️Since opposite sides of a parallelogram are parallel, therefore:
m<2 = 53° (alternate angles)
✔️Diagonals bisect each angle of a parallelogram, therefore,
m<3 = m<2
m<3 = 53°
✔️m<4 + m<3 + 90° = 180°(sum of triangle)
m<4 + 53° + 90° = 180° (substitute)
m<4 = 180 - 143
m<4 = 37°

Solve for x. Round answer to the nearest tenth.
X
759
17
Answer:
x ≈ 4.6
Step-by-step explanation:
Reference angle = 75°
Opposite side to reference angle = 17
Adjacent side = x
Applying TOA:
Tan 75 = opp/adj
Tan 75 = 17/x
Multiply both sides by x
x*Tan 75 = 17
Divide both sides by Tan 75
x = 17/Tan 75
x ≈ 4.6
A sample of students is taken from the school’s A honor roll. The school estimates that there are actually 360 students on the A honor roll. Using this sample, how many students on the A honor roll are 8th graders?
6thgraders=15
7thgraders=11
8thgraders=14
Answer:
Number of 8th Graders = 360 - X
As you can see this question is not complete and lacks the essential data. But we will try to create a mathematical expression to calculate the number of students on the A honor roll which are from 8th grade.
As we know:
Total number of students on the A honor roll = 360
We are asked to calculate, number of students from 8th grade on the A honor roll.
So, let's assume that "X" represents all the students who are on the A honor roll except 8th grade.
Mathematical Expression:
Number of 8th Graders = Total number of students on the A honor roll - X
Number of 8th Graders = 360 - X
So, if you know the value of X, you can easily calculate the number of students which are from 8th grade on the A honor roll.

Answer:
557.8
Step-by-step explanation:
Because the semi circle on the top and the semi circle on the bottom form a circle with an area of 314.16.
The semicirlces on either side form a circle with an area of 66.48.
Then the rectangle in the middle has an area of 9 times 20 which is 180.
If you add those areas together you get the total area which is about 557.8
I hope this is helpful :)
