Answer:
x = 9°
Step-by-step explanation:
The full arc of the angles equals 360°. So, we can subtract all of the measures of angles we are given from the total 360 to find the value of x.
We can add the given angles together and subtract the sum from 360 as well.
73 + 63 + 89 = 225
This means the measure outside 15x is a combines 225°.
Now, subtract the known measures from our total, 360.
360 - 225 = 135
The unknown, or 15x, is equal to 135°.
15x = 135
Solve this like a normal equation. Divide both sides by 15 to isolate x and solve for the variable.
[tex]\frac{15x}{15}[/tex] = [tex]\frac{135}{15}[/tex]
x = 9
x is equal to 9°.
We can check by adding all our values together again to see if they amount to 360°.
73 + 63 + 89 + 15(9) = 360
360 = 360
The equation is correct, so we can be sure that we are right.
The answer is x = 9°.
Good luck ^^

a 400 g of a liquid of density 1.6g/cm3 is made from mixing liquids of density 1.2g/cm3 and 1.8g/cm3 find the mass of the liquid of density 1.2g/cm3
Answers
Answer:
133.33g
Step-by-step explanation:
Let the:
Mass of 1.2g/cm³ of liquid = x
Mass of 1.8g/cm³ of liquid = y
From our Question above, our system of equations is given as:
x + y = 400........ Equation 1
x = 400 - y
1.2 × x + 1.8 × y = 1.6 × 400
1.2x + 1.8y = 640..... Equation 2
We substitute, 400 - y for x in Equation 2
1.2(400 - y) + 1.8y = 640
480 - 1.2y + 1.8y = 640
- 1.2y + 1.8y = 640 - 480
0.6y = 160
y = 160/0.6y
y = 266.67 g
Solving for x
x = 400 - y
x = 400 - 266.67g
x = 133.33g
Therefore, the mass of the liquid of density 1.2g/cm³ is 133.33g
Miss Clara, the teacher at the school, has one
large classroom with 25 students. The
dimensions of the classroom are 30 units by
30 units. Each desk is two units wide by
three units long. How much space will be
leftover after all the desks are in the room?
Answers
Answer:
750 units.
Step-by-step explanation:
30 x 30 = 900 units (total space in the classroom)
2 x 3 = 6 units (how much space each desk takes up)
25 x 6 = 150 units (number of desks for each student)
900 - 150 = 750 units

A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 9cm, and the base has a radius of 4cm. How much water is needed to fill 150 cups? Use 3.14 for π, and do not round your answer.
Answers
Answer:
22608cm³
Step-by-step explanation:
Step 1
We find how many liters of water can be contained in 1 cup. We do this by finding the volume of the cup.
Cup is shaped as a cone
The volume of a cone = πr²h/3
Where
r = radius = 4cm
h = height = 9cm
π = 3.14
Hence,
Volume of the cone (cup) =
3.14 × 4² × 9/3
= 150.72 cm³
Step 1
How much water is needed to fill 150 cups?
1 cup = 150.72 cm³ of water
150 cups = x
Cross Multiply
x = 150 × 150.72 cm³
x = 22608 cm³ of water
Therefore, 22608cm³ of water is needed to fill 150 cups

Answer:
D. 2%
Step-by-step explanation:
The growth rate can be found by looking at the growth factor of the exponential function.
f(x) = (initial value) × (growth factor)^x
The growth rate is related by ...
growth factor = growth rate + 1
This means the growth rate of f(x) is 1.04 -1 = 0.04 = 4%.
__
We can write the function g(x) describing the table as ...
g(x) = (value at x=x1) × ((value at x=x2)/(value at x=x1))^((x-x1)/(x2-x1))
So, this could be ...
g(x) = 31.21 × (32.47/31.21)^((x-2)/2) = a·b^x
where b = (32.47/31.21)^(1/2) ≈ 1.02 . . . . growth factor
This means the growth rate for g(x) is 1.02 -1 = 0.02 = 2%.
__
Then the difference between the growth rates of the two functions is ...
4% - 2% = 2% . . . . . matches choice D

The longest straw that can fit inside a 5-inch cylindrical cup, if the straw is placed at an angle in the cup, is 6 inches.
Then the approximate length of the cylinder's radius will be given by the Pythagoras theorem.
Let x be the length of the radius. Then we have
x² = 6² - 5²
x² = 36 - 25
x² = 11
x = √11
