Answer:
18x ≥ 160
Step-by-step explanation:
Ashley has two jobs: mowing lawns and babysitting. She earns $10 per hour mowing lawns (x) and $8 per hour babysitting (y). And she wants to earn at least $160 per week.
Let the number of hours = x
At least = Greater than or equal to
Slope intercept form
= y = mx + c
y = $160
Hence
10x + 8x ≥ 160
18x ≥ 160

The diameters of ball bearings are distributed normally. The mean diameter is 107 millimeters and the population standard deviation is 5 millimeters.
Find the probability that the diameter of a selected bearing is between 104 and 115 millimeters. Round your answer to four decimal places.
What is the notation?
Answer:
0.6710
Step-by-step explanation:
The diameters of ball bearings are distributed normally. The mean diameter is 107 millimeters and the population standard deviation is 5 millimeters.
Find the probability that the diameter of a selected bearing is between 104 and 115 millimeters. Round your answer to four decimal places.
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 107 mm
σ is the population standard deviation = 5 mm
For x = 104 mm
z = 104 - 107/5
z = -0.6
Probability value from Z-Table:
P(x = 104) = 0.27425
For x = 115 mm
z = 115 - 107/5
z = 1.6
Probability value from Z-Table:
P(x = 115) = 0.9452
The probability that the diameter of a selected bearing is between 104 and 115 millimeters is calculated as:
P(x = 115) - P(x = 104)
0.9452 - 0.27425
= 0.67095
Approximately = 0.6710

5. Write the slope-intercept form of the equation that passes through the point (-1, 2) and is perpendicular to the line y = 3/2x + 6
O y = 3/2x + 5/2
O y = 3/2x + 4/3
O y = -2/3x + 5/2
O y = -2/3x + 4/3
Answer:
D. y = -2/3 x + 4/3
Step-by-step explanation:
When you have a perpendicular line, everything except the y-intercept becomes opposite. So 3/2x + 6 will become -2/3x.
To find the slope, you have to plug the coordinates into the equation so far which is y = -2/3x + b
y = -2/3x + b
2 = -2/3(-1) + b
2 = 2/3 + b
4/3 = b
So the equation is y = -2/3 x + 4/3.
A circle has a radius of 5p6q3 cm. The area of the circle can be found using the formula A = πr2. What is the area of this circle in square centimeters?
Answer:
25p^12q^6πcm²
Step-by-step explanation:
Given the area of the circle expressed as;
A = πr^2
Given
r = 5p^6q^3 cm
Substitute into the formula
A = π(5p^6q^3 )²
A = π(25p^12q^6)
A = 25p^12q^6πcm²
hence the area of this circle in square centimeters is 25p^12q^6πcm²
The area of the circle whose radius be 5p⁶q³ is 25πp¹²q⁶ square centimeters.
What is a circle?It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
A circle has a radius of [tex]\rm 5 \ p^6 \ q^3[/tex] cm.
The area of the circle can be found using the formula
[tex]\rm A = \pi \ r^2[/tex]
Then the area of the circle will be
[tex]\rm A = \pi (5 \ p^6 \ q^3)^2\\\\A = \pi * 5^2 \ (P^6)^2 (q^3)^2\\\\A = 25 \ \pi \ p^{12} \ q^6[/tex]
Thus, the area of the circle is 25πp¹²q⁶ square cm.

Step-by-step explanation:
Martin is making a model of a Native American canoe. He has 5 1/2 feet of wood he uses 2 3/4 feet for the whole and 1 1/4 feet for a paddle how much does he have left
This is calculated as:
5 1/2 feet - ( 2 3/4 feet + 1 1/4 feet)
Lowest Common Denominator 4
5 1/2 feet - (2 + 1 ( 3 + 1/4)

Find a and b.........
Answer:
a is 10
b is 37
Step-by-step explanation:
Now we must agree that the diagram above is a parallelogram.
this figure has its opposite sides parallel to each other, and also equal to each in length, this means a+5=15.
hence a is 10.
and the opposite angles of the parallelogram are equal thus, 111=3b,
hence b is 37°.
I must say I was shocked to see 111 is divisible by 3...
well you can follow me, for questions or further explanations.

Answer:
B.) y - 6 = -8/5(x + 2)
Step-by-step explanation:
Remember in order to find the slope intercept form on 2 points, you need these equations: [tex]\frac{x_2 -x_1}{y_2 -y_1}[/tex] and [tex]y-y_1=m(x-x_1)[/tex]
To find the slope, you will need to use the first equation. In this case the equation will look like this: [tex]\frac{(-2)-6}{3-(-2)}=-\frac{8}{5}[/tex]
Then use the second equation, plug in the numbers, and you will get B as your answer
a spherical snow globe has a diameter of 4 inches. what is the volume, in cubic inches, of the spherical part of the snow globe
Answer:
The volume of the snow globe is 78 cubic inches.
Step-by-step explanation:
Given:
A snow globe consists of a pedestal in the shape of a cube with a sphere mounted on top of the pedestal. The pedestal has an edge length of 4 inches and the sphere has a diameter of 3 inches.
Now, to get the volume of the snow globe.
So, we get the volume of pedestal which is in the shape of cube by putting formula:
Edge = 4 inches.
Volume of pedestal = 64 cubic inches.
Now, to get the volume of sphere by putting formula:
Diameter = 3 inches.
Radius () =
Volume of sphere = 14.131 cubic inches.
Now, to get the volume of snow globe by adding both the volumes, the volume of sphere and the volume of pedestal:
Rounding to the nearest cubic inch = 78 cubic inches.
Therefore, the volume of the snow globe is 78 cubic inches.
What is 35% of 78?
