Krissa exercises daily by walking. She aims to walk at a steady rate of 3.4 miles per hour.
a. If t represents time in hours and d represents distance in miles, write an equation that models the relationship between these variables.
b. Use your equation to calculate the distance Krissa will jog in 5/8 of an hour (round to the hundredths).
c. Use your equation to calculate how long it will take for Krissa to walk 5.44 miles.
Answer:
a. 3.4t (miles)
b. 2.125 miles
c. t = 1.6 hours
Step-by-step explanation:
A) We use this relation: Distance = time * speed ( speed or vitesse or rate)
So d= 3.4*t= 3.4t (miles)
B) If t= 5/8
then the distance d= 3.4* 5/8= 2.125 miles.
C) If the distance d= 5.44, we can find the time like:
d= 3.4*t, and we know d=5.44
so 5.44= 3.4*t or t = 5.44/3.4, t= 1.6 hours
Hope you understand it.

Angle T and angle V are complementary angles. If cos T = 0.75, which statment is always true?
Complementary angles T and V would add up to 90 degrees
The true statement is sin V = 0.75
How to determine the correct statement?The given parameters are:
cos T = 0.75
Angles T and V are complementary angles
The second highlight above means that:
T + V = 90cos T = sin Vsin T = cos VSubstitute 0.75 for cos T in cos T = sin V
0.75 = sin V
Rewrite as:
sin V = 0.75
Hence, the true statement is sin V = 0.75

Answer:
(- 21, - 13 )
Step-by-step explanation:
- 3y + x = 18 → (1)
x = 2y + 5 → (2)
substitute x = 2y + 5 into (1)
- 3y + 2y + 5 = 18
- y + 5 = 18 ( subtract 5 from both sides )
- y = 13 ( multiply both sides by - 1 )
y = 13
substitute y = - 13 into (2)
x = 2(- 13) + 5 = - 26 + 5 = - 21
solution is (- 21, - 13 )
Divide (6x3y2 + 12x2y - 8xy) by (2xy)
Answer:
Step-by-step explanation:
6x³y² = 2 * 3 * x³ * y²
12x²y = 2 *3 * 2 * x² * y
8xy = 2 * 2 * 2 *x * y
GCF = 2xy
6x³y² + 12x²y - 8xy = (2xy * 3x²y) + (2xy * 6x) - (2xy * 4)
= 2xy *(3x²y + 6x - 4)
[tex]\dfrac{6x^{3}y^{2}+12x^{2}y-8xy}{2xy}=\dfrac{2xy*(3x^{2}y+6x-4)}{2xy}\\\\\\= 3x^{2}y + 6x - 4[/tex]

Heather is planning to buy a home. She would need to borrow $200,000 from a bank over a 30-year period. The monthly payment is $1800. What will be her total interest for the 30 years?
Answer:
Below.
Step-by-step explanation:
Total payment = 1800 * 30 * 12 = 648,000.
Interest = 448,000.
Heather should have to pay total of $648,000 to the bank and Interest Heather will pay to the bank is $448,000.
What is interest?Interest is the price you pay to borrow money or cost you charge to lend money. Interest can be calculated by total amount you paid after a specific time period minus the total amount you borrowed.
Heather borrowed $200,000 from a bank over a period of time 30 year.
30 year = 12×30monts
=360 months
Now, The monthly payment to the bank is = $1800
Therefore total payments in 360 months is = 360×$1800
=$648,000
Bank Interest = $648,000 - $200,000
=$448,000
Hence , Heather total interest after 30 years will be =$448,000

Is the vertex maximum or a minimum
Step-by-step explanation:
In this case the vertex is a maximum since it's in the shape of a hill not a valley. Vertex is (0,4)
Answer:
Maximum
Step-by-step explanation:
It is the maximum of the graph because it is the highest (MAXIMUM) point on the graph that the line reaches. If it were upside down, and the vertex was at the bottom and was the lowest point of the line, then it would be the minimum.

Amelia wants to paint 3 walls in her family room. Two walls are 26 feet long by 9 feet wide. The other wall is 18 feet long by 9 feet wide.
A. What is the total area of the walls that Amelia wants to paint?
B. Each gallon of paint covers about 250 square feet. How many gallons of paint should Amelia buy to paint the walls?
Answer:
x = 2.52 gallons. It is best that she buy 3 gallons of paint.
Step-by-step explanation:
Wall 1 & 2 : 26 ft by 9 ft
Wall 3 : 18 ft by 9 ft
Area 1 : 26 ft x 9 ft = 234 ft²
Area 2 : 26 ft x 9 ft = 234 ft²
Area 3 : 18 ft x 9 ft = 162 ft²
Total Area : 234 ft² + 234 ft² + 162 ft² = 630 ft²
1 Gallon = 250 ft²
630 ft² ÷ 250 ft² per gallon = 2.52 gallons
Amelia will need 2.52 gallons of paint to cover the wall space of 630 ft^2

Step-by-step explanation:
36x=32x-1
We move all terms to the left:
36x-(32x-1)=0
We get rid of parentheses
36x-32x+1=0
We add all the numbers together, and all the variables
4x+1=0
We move all terms containing x to the left, all other terms to the right
4x=-1
x=-1/4
x=-1/4
