Answer:
110
Step-by-step explanation:
Hello There!
If you didn't know the rule about angles in a triangle is that they have a sum of 180
So we can find the measure of the missing angle by subtracting the given angles (in this case 30 and 40) from 180
so the missing angle = 180 - 30 - 40
180 - 30 = 150
150 - 40 = 110
so the missing angle = 110

What are Quadratic Equations?Quadratic equations are polynomial equations of second degree.
The general form of a quadratic equation is ax² + b x + c = 0.
The given quadratic equation is,
2x² - 5x - 7 = 0
The solutions of a quadratic equation can be found using the quadratic formula.
Quadratic formula for ax² + b x + c = 0 is,
x = [-b ± [tex]\sqrt{b^2-4ac}[/tex] ] / 2a, where [tex]\sqrt{b^2-4ac}[/tex] is called discriminant.
From the given equation,
a = 2, b = -5 and c = -7.
Solution can be found as,
x = -(-5) ± [tex]\sqrt{(-5)^2-(4*2*-7)}[/tex] ] / (2 × 2)
= [5 ± √(25 + 56) ] / 4
= [5 ± √81] / 4
Hence the solution can be found as [5 ± √81] / 4.

The mean of ten numbers is 13. What eleventh number, if included with the original numbers, would result in a mean of 12?
Answer:
2
Step-by-step explanation:
To find the mean, you divide the number you get from adding all the numbers by the number of numbers. In this case, we know the mean and the number of numbers but don't know the number you get from adding all the numbers. So, we have to do the reverse operation meaning we have to multiply 13 and 10 together which would equal 130.
Now, we do the same thing with 11 and 12, we multiply! 11 x 12 = 132.
130 + 2 = 132, meaning the answer is 2.
You're welcome!
The eleventh number, if included with the original numbers, would result in a mean of 12 is; x = 2
Formula for mean is;
Mean = Sum of numbers/sample size
We are given;
Mean = 13
Sample size = 10
Thus, sum of numbers = 13 × 10 = 130
Now, we want to add an eleventh number so that the mean will be 12.
Thus, n = 11
12 = (130 + x)/11
Cross multiply to get;
12 * 11 = 130 + x
x = 132 - 130
x = 2
Thus, the eleventh number, if included with the original numbers, would result in a mean of 12 is; x = 2

What is the length of the diagonal of the rectangle?
9514 1404 393
Answer:
21.25
Step-by-step explanation:
The Pythagorean theorem tells you the length of hypotenuse c of a right triangle with legs 'a' and 'b' is ...
c = √(a² +b²)
Here, that means the diagonal length d is ...
d = √(17² +12.75²) = √(289 +162.5625) = √451.5625
d = 21.25 . . . . length of the diagonal

One shape is approaching a poor from the east traveling west at 15 mph and its presently 3 miles east east of the port I second ship is already left the poor traveling to the north at 10 mph and is presently 4 miles north of the port at this instant what is the rate of change of distance between the two ships are they going to close your more for their apart
Answer:
DL/dt = 17 mph
Step-by-step explanation:
The ships and the port shape a right triangle
Ship going west ( x-direction) is traveling at 15 mph
Ship going north (y-direction) is traveling at 10 mph
The distance L between ships is:
L² = x² + y²
Tacking derivatives on both sides of the equation with respect to time
we get
2*L*DL/dt = 2*x*Dx/dt + 2*y*Dy/dt (1)
In that equation we know:
Dx/dt = 15 mph
Dy/dt = 10 mph
At the moment ship traveling from the east is at 3 miles from the port
then x = 3 m and the other ship is at 4 miles north
then by Pythagoras theorem
L = √ 3² + 4² L = 5
By substitution in equation 1
2*5*DL/dt = 2*3*15 + 2*4*10
10* DL/dt = 90 + 80
DL/dt = 170 / 10
DL/dt = 17 mph

Two gyms open their memberships to the public. Compare the gyms by calculating and interpreting the average rates of change from Week 1 to Week 3.
From Week 1 to Week 3, Gym A membership increases at an average rate of _ people per week, and Gym B membership increases at an average rate of _ people per week. So, Gym _ membership is growing faster.
Answer:
Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.
Step-by-step explanation:
To find the average membership in Gym A is simple. To get 72 to 124, we need to subtract them getting 52, this is the same for the other weeks. So, Gym A gets 52 members per week. Gym B is a bit more complex, each week has to be constant so subtract 204 by 80 and you get 124. Divide 124 by 2 because the difference between Week 1 to 3 is 2. Then we get 62 some Gym B gets 62 average members per week. Hope this helps. Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.
Gym A gets 52 people per week and Gym B gets 62 people per week hence, Gym B is growing faster.
What are average?The average can be calculated by dividing the sum of observations by the number of observations.
To determine the average membership in Gym A is simple.
Therefore, to get 72 to 124, we need to subtract them getting 52, this is the same for the other weeks.
Gym A gets 52 members per week. Gym B is a bit more complex, each week has to be constant so,
204 -80 = 124.
Now Divide 124 by 2 because the difference between Week 1 to 3 is 2.
Then we get;
62 some Gym B gets 62 average members per week.
Hence, we can conclude that Gym A gets 52 people per week and Gym B gets 62 people per week.

Marina is drawing a plan for a new garden. The rectangle plotted in the coordinate plane represents the garden, measured in feet. How much soil will she need to cover the garden? 10 ft2 12 ft2 20 ft2 24 ft2
Answer:
Step-by-step explanation:
You need to upload a picture and i can answer underneath.
Usually if measured in feet then we have a scale = 1cm -1ft maybe.
so if you measure 3cm x 4cm then we have 12cm area = 12ft area if. Or if you have 2cm x 5cm = 10cm area = 10ft area if you have 4cm x 5cm = 20cm = 20ft area
etc. etc. Just make sure you say cm then ft in scale conversion.
