what is the slope or the line going through (0,0) (6,8) A: -6/8 B: -3/4 C: 3/4 D: 8/6
Answer:
D: 8/6
Step-by-step explanation:
Slope = y 2 - y 1
x2 - x1
= 8 - 0
6 - 0
=8
6
Answer: D. 8/6
Step-by-step explanation:
To solve this, we can use the slope formula, which is
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] ← this is [tex]\frac{rise}{run}[/tex]
Plugging in the values of the two points, we get:
[tex]\frac{8 - 0}{6 - 0} = \frac{8}{6} = \frac{4}{3}[/tex]
In your case though, it is D. 8/6
3/10 divided by -1/3
Answer:
3/10 divided by 1/3= 0.9
Step-by-step explanation:
∠1 and ∠2 are complementary angles. Given m∠1=83°, find m∠2.
Reasoning: Complementary angles always add to 90 degrees.
If angle 2 was x, then x+83 = 90 solves to x = 7
The measure of m∠2 is 7° due to the pair of angles being complementary.
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.
Adjacent angles: Adjacent angles are the type of supplementary angles. Adjacent angles have a common side and vertex, for example, a corner point. Their points do not overlap in any way. In other terms, adjacent angles are pairs of two angles next to each other.
We have been given that the pair of angles as
m∠1 = 83° and m∠2 = x
Here, the pairing of angles sums up to 90° then they are called complementary angles.
So x + 83 = 90°
⇒ x = 90° - 83°
⇒ x = 7°
Therefore, the value of m∠2 is 7°.

If the pattern indicated below continued, what would be the total number of cubes in the 8th stage of the pattern?
1, 1+4=5, 1+4+9=14
Answer:
The number of cubes in the 8th stage of the pattern is 204
Step-by-step explanation:
Here, we want to calculate simply the 8th term of the pattern
T1 = 1
T2 = 1 + 4 = 1 + 2^2 = 5
T3 = T2 + 3^3 = 5 + 9 = 14
T4 = T3 + 4^2 = 14 + 16 = 30
T5 = T4 + 5^2 = 30 + 25 = 55
T6 = T5 + 6^2 = 55 + 36 = 91
T7 = T6 + 7^2 = 91 + 49 = 140
T8 = T7 + 8^2 = 140 + 64 = 204

What is the answer for this expression
Answer:
x=-7
Step-by-step explanation:
1. Distribute the 7 into the parenthesis: -7-2x=7x+56
2. Combine like terms by doing the opposite operation to the numbers: -7=9x+56 (added 2x to 7x)
3. Subtract 56 to each side of the equation: -63=9x
4. To isolate the variable "x," divide each side by 9: x=-7

Step-by-step explanation:
630 ÷ 7 ÷ 2 ⋅ 9 ⋅ 25 = 125
(630 ÷ 7) ÷ (2 ⋅ 9) ⋅ 25 = 125
90 ÷ 18 ⋅ 25 = 125
5 ⋅ 25 = 125

A motorboat heads upstream a distance of 24 miles on the Guadalupe River, whose current is flowing at 3 miles/hour. Which expression can represent the total time it takes to complete a round-trip up and back, where b is the speed of the boat in miles/hour?
Answer:
24/b-3 + 24/b+3
Step-by-step explanation:
For PLATO users!!!!
This expression represents the total time, Time = [tex]\frac{24}{b-3} + \frac{24}{b+3}[/tex]
What is distance?Distance is defined as the product of the speed and time.
Given,
b = the speed of the boat in miles/hour
let, effective speed upstream = (b+3)
effective speed downstream = (b-3)
∵Time = distance/ speed
Given that, upstream a distance of 24 miles
Time = [tex]\frac{24}{b-3} + \frac{24}{b+3}[/tex]
This expression represents the total time it takes to complete a round-trip up and back.

15(t+2)+9t=6 Please help!
Answer:
t = -1
Step-by-step explanation:
15(t+2)+9t=6
15t + 30 + 9t = 6
combine like terms
24t +30 = 6
subtract 30 both sides
24t = -24
t = -1
22-5(6v-1) = -63
22- 30v + 5 = -63
27 -30v = -63
subtract both sides by 27
-30v = -90

francis made a rectangular path from her driveway to the porch . the width of the path is 2 ft and the length is 28 ft longer than the width . what is the perimeter of the path
The perimeter of the rectangular path is 64 ft
What is a Rectangle?Rectangle is a type of quadrilateral that has its parallel sides equal to each other, opposite sides are equal to each other, and all the angle are equal to 90 degrees.
How to determine this
The perimeter of a Rectangle = 2 ( Length + Width)
Where the Width = 2 ft
Length = 28 ft longer than Width
i.e W + 28
Length = 2 + 28 = 30 ft
To calculate the perimeter if the path
Perimeter = 2( 30 + 2)
Perimeter = 2(32)
Perimeter = 64 ft
Therefore, the perimeter of the rectangular path is 64 ft

Denise earns $30 an hour. She works 40 hours per week. Denise would like to purchase a computer that costs $2000. Create and solve an inequality in order to determine the least amount of hours she must work in order to be able to purchase the computer?
Answer:
67hours hoursStep-by-step explanation:
Given
she works $30 for 1 hour
in 40 hours she will earn 40*30= $1200
this means that a week she earns $1200
let the number of weeks she needs to work be x
40x*(30)<=2000
1200x<=2000
x<=2000/1200
x<=1.66
the number of hours in a week is 40
40*1.66=66.66
67hours
hence she must work for at least 67hours

B. 39/111
C. 111/189
D. 189/150
E. 39/150
Answer:
A. 111/150
Step-by-step explanation:
Because we know that 39 people out of the 150 in the group wear glasses, we need to subtract that from the total. This gives us 111 people that don't wear glasses.
Therefore, the probability of choosing someone not wearing glasses is 111/150.
