days. The total cost, c, of the boat rental is
proportional to the number of days, d, the
family rents the boat.

A. How much does it cost, in dollars, to
rent the boat for 3 days? SHOW
WORK!
B. Create an equation using "c" and "d" to
represent the proportional relationship
Answer:
A: $45 for 3 days
B: c=d(15)
Step-by-step explanation:
A: If 105 is the cost for 7 days and we want to find the cost for only 3 we have to find the cost for one day to start with so, 105 divided by 7 which is $15 so its 15 dollars a day then you multiply 15 by the number of days we want (3) and you get $45.

In Δ ABC and ΔXYZ ,∠B=∠X=90 and BC=XZ .What additional information is required to make Δ ABC congruent to ΔXYZ by R.H.S condition.
Answer:
AC = XY
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.
Two triangles are said to be congruent if all the three sides and three angles of one triangle is equal to the three sides and three angles of the other triangle.
In Δ ABC and ΔXYZ ,∠B=∠X=90. This means that triangle ABC and triangle XYZ are right angled triangle since one of their angles is 90 degrees.
The hypotenuse is the side opposite to right angle (90 degrees).
Therefore AC is the hypotenuse of triangle ABC and YZ is the hypotenuse of triangle XYZ.
If the hypotenuse and one leg of a right angled triangle is equal to the hypotenuse and leg of another right angled triangle, then the two triangles are congruent by RHS rule.
Since BC = XY, for Δ ABC congruent to ΔXYZ by R.H.S condition, the hypotenuse have to be equal, i.e. AC = XY

Answer:
x = 4
Step-by-step explanation:
If a line is parallel to a side of the triangle and intersects the other 2 sides then it divides those sides proportionally, that is
[tex]\frac{2}{4}[/tex] = [tex]\frac{x-1}{6}[/tex] ( cross- multiply )
4(x - 1) = 12 ( divide both sides by 4 )
x - 1 = 3 ( add 1 to both sides )
x = 4

Write the equation of a line through (-1,-5) parallel to 3x-y=5, and in slope intercept form
Answer:
y =3 x
Step-by-step explanation:
The standard equation of a line in point slope form is expressed as;
y -y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
Given the line 3x - y = 5
Get the slope
- y = -3x + 5
y = 3x - 5
Slope m = 3
Substitute m = 3 and (-1, -5) into the given formula
y - (-5) = 3(x-(-1))
y+5 = 3(x+1)
y + 3 = 3x+3
y = 3x + 3 - 3
y = 3x
Hence the equation in slope intercept form is y =3 x

Answer:
1. b
2. c
3. d
4. a
5. e
Step-by-step explanation:
When the equation is written in slope-intercept form of ;
y = mx + b, then m is the slope and b is the y-intercept
In this case;
1. y= -7/6x + 1 --------- m= -7/6 ; b = 1 --------b
2. y=7/6x -1 ------------m = 7/6 ; b = -1 ---------c
3. y= x-7/6 -------------m = 1 ; b = -7/6 ---------d
4. y= -x -7/6 ----------m =-1 ; b = -7/6 ----------a
5. -x + 6/7 ------------m = -1 ; b = 6/7---------e
Find the volume of this prism.
9 cm
12 cm
6 cm
PLEASE HELP
Answer:
324cm³
Step-by-step explanation:
Volume of a triangular prism = (height x width x base length) / 2
We are given:
Height = 9cm Base length = 6cmWidth = 12cmIf we plug this into the formula we get (9 x 6 x 12) / 2
==> multiply numbers in parenthesis
volume = 648/2
==> simplify division
volume = 324cm³

A beekeeper pays $30 to rent a booth at a farmers' market.
She charges $5 for each jar of honey. The graph shows this
situation, which is modeled by the equation y = 5x - 30.
Which of the following is true?
A. The value of x can be negative.
B. The value of y can be negative.
C. The value of x can be fractional.
D. The value of y cannot be zero.
X
Answer: The answer is A
Step-by-step explanation: because 5x-30= -150 because I looked it up
Answer:
B. The value of y can be negative.
Step-by-step explanation:
The value of y can be negative, which means the beekeeper wasn't able to sell a lot of jars that could compensate the amount he paid for the booth. It also means he didn't have any profit, rather, he incurred a loss.
For example, if the beekeeper sold only 5 jars of honey, the solution will look like this:
Let x be the number of jars of honey the beekeeper sold.
y = 5x - 30y = 5(5) - 30y = 25 - 30y = -5This means that the beekeeper has a loss of $5.
Does an equation in slope-intercept form represents a straight line?

Depends. Usually it goes across the graph but other times you'll have a vertical or horizontal one. Depending on what the points were.
Nina's grandmother deposits 3000 into a saving account for her account pays 5.5% simple interest on an annual basis if she does not add or withdraw money from the account how much interest will she earn after 21 months round to the nearest tenth
Nina's grandmother earn $288.75 interest after 21 months.
What is Simple interest?
The cost of borrowing money without accounting for the effects of compounding is called Simple interest.
Given that;
Principal amount (P) = 3,000
Rate (R) = 5.5%
Time (T) = 21 month = 1 9/12 years
Now, The formula for the interest is;
Interest = P × R × T / 100
Where, P is the principal amount of money, R is the interest rate, T is the time.
Substitute all the values we get;
Interest = 3,000 × 5.5 × 1 9/12 / 100
= 55 × 21 / 4
= 288.75
Thus, Nina's grandmother earn $288.75 interest after 21 months.

One evening, the temperature drops 12 °F to become 37 °F. What was the temperature at the beginning of the evening? Write and solve an equation to represent this situation.
Answer: 49°F
Step-by-step explanation: x - 12 = 37, So all we have to do is reverse it. That means we add 37 and 12 to get the beginning temperature. 37 + 12 = 49. So at the beginning of the evening, it was 49°F.
