Find the slope: (-2, -5), (7, 8)
Answers
Answer:
Step-by-step explanation:
Slope = (8 - (-5)) / (7 - (-2))
Slope = (8 + 5) / (7 + 2)
Slope = 13/9
So, in conclusion, the slope of this line is: 13/9 which means that for every 13 units you go up, you go 9 units to the right.

Carmen rents roller skates for $5 plus $2 for every hour she uses them. Define the variable and write an expression for the total cost to rent roller skates. Then find the total cost if Carmen rest them for 4 hours.
Answers
Given:
Carmen rents roller skates for $5 plus $2 for every hour she uses them.
To find:
The expression for the total cost to rent roller skates. Then find the total cost if Carmen rest them for 4 hours.
Solution:
We have,
Fixed rent = $5
Additional rent = $2 per hour.
Let x be the number of hours.
So, additional rent is $2x.
Now,
Total rent = Fixed rend + Additional rent
= $(5+2x)
So, the expression for total cost is $(5+2x).
Carmen rent them for 4 hours. So, x=4 and the total cost is
[tex]\text{Total cost}=5+2(4)[/tex]
[tex]\text{Total cost}=5+8[/tex]
[tex]\text{Total cost}=13[/tex]
Therefore, the total cost of 4 hours is $13.

Answers
Answer:
Isabelle sold 60% of the corn on Saturday
Step-by-step explanation:
In order to calculate the percentage of the corn that Isabelle sold we first need to divide the number of corn that she sold by the total number of corn that she had initially.
150 / 250 = 0.6
Now we simply need to multiply this decimal value by 100. This will give us the percentage of corn sold as a percentage value.
0.60 * 100 = 60%
Therefore, we can see that Isabelle sold 60% of the corn on Saturday

Answer:
X = 62°
Step-by-step explanation:
Since opposite or vertical angles are equivalent, you can form the equation that 28 + x = 90 (In case you didn't know, right angles are always 90°). Subtract 28 from both sides to find the value of x and you'll get x = 90 - 28 or x = 62°.

If 8 engines consume 12000 kgs. of coal when each running 10
hours per day, how much coal is required for 7 engines out
which 5 are running 12 hours a day and the rest 6 hours a day?
Answers
Answer:
11200 for 7 engines for a total of 80 hours
Step-by-step explanation:
You have 8 engines burning 12000 .for 10 hours.
Divide 10 hours into 12000=1200 PER hour.
1200 ÷8 engines = 140 per hour per engine.
140 × # of hours (12)=1680 for 12 hours per engine.
# of engines × 1680 for 12 hour/per engine
5×1680 = 8400 of fuel for 12 hours/5 engine
Then you have 2 that runs 10 hours
2 × 140 per hour per engine =280 × 10 =2800 for 2 engines for 10 hours
8400. + 2800= 11200 of fuel for 6 engines

Step-by-step explanation:
In a triangle, all of the interior angles add up to 180 degrees. Knowing this, we can construct the following equation and solve for x:
[tex]x+2x+45=180\\3x+45=180[/tex]
Subtract both sides by 45
[tex]3x+45-45=180-45\\3x=135[/tex]
Divide both sides by 3
[tex]\frac{3x}{3} =\frac{135}{3} \\x=45[/tex]
