5.Monty made a scale drawing of his room on grid paper, as shown below.
If each square on the grid paper represents a side length of 2 feet, what is the length, in feet,
of the longest wall in the room
Answer: 16 feet
Step-by-step explanation:
Looking at the drawing, the longest wall in the room is the horizontal length of the scale drawing.
Looking at the longest wall, the number of squares with a side length on the line of the wall are 8 in number.
If each square represents a side length of 2 feet, the length of the wall will be;
= 2 * 8
= 16 feet
Two numbers A and B are such that the sum of 5% of A and 4% of B is two-third of the sum of 6% of A and 8% of B. Find the ratio of A : B.
Answer:
a : b = 4 : 3
Step-by-step explanation:
(mark as brainlist answer)
According to the given condition is the question :
Two numbers a and b are such that the sum of 5% of a and 4% of b is two-third of the sum of 6% of a and 8% of b
⇒ (5% of a) + (4% of b) = (2/3) × [(6% of a) + (8% of b)
⇒ 0.05a + 0.04b = 2/3 × (0.06a + 0.08b)
⇒ 0.15a + 0.12b = 0.12a + 0.16b
⇒ 0.03a = 0.04b
⇒ a/b = 4/3
⇒ a : b = 4 : 3

Atlantic boat rental charges a $35.50 deposit fee plus $12.25 per hour to rent the boat. Pacific boat rental charges $25.99 plus $14.99 per hour to rent the boat. How many hours would you have to rent the boat for the cost of both rentals be the same? Select the equation that represents this situation. 35.50 - 12.25x = 25.99 - 14.99x 35.50 - 12.25x = 25.99 - 14.99x 35.50 + 12.25x = 25.99 + 14.99x 35.50 + 12.25x = 25.99 + 14.99x 35.50x + 12.25 = 25.99x + 14.99 35.50x + 12.25 = 25.99x + 14.99 12.25x - 35.50 = 14.99x - 25.99
Answer:
35.50 + 12.25x = 25.99 + 14.99x
Step-by-step explanation:
Given
Atlantic Boat
Deposit = $35.50
Hourly Rate = $12.25
Pacific Boat
Deposit = $25.99
Hourly Rate = $14.99
Required
Determine the equation that represents when both charges would be equal
Represent the number of hours with x
For both rental agencies, the hourly rate would be calculated using:
Deposit + Hourly Rate * x
So, for Atlantic Boat, the expression is:
35.50 + 12.25 * x
35.50 + 12.25x
For Pacific Boat, the expression is:
25.99 + 14.99 * x
25.99 + 14.99x
Next, is to equate both expressions.
This, when solved would get the number of hours when there charges would be the same.
35.50 + 12.25x = 25.99 + 14.99x
Solving further:
Collect like terms
35.50 - 25.99 = 14.99x - 12.25x
9.51 = 2.74x
Divide through by x
x = 9.51/2.74
x = 3.47 hours

The Point (0,0) is a solution to which of these inequalities?
Answer:
(0, 0) s the solution of y-4 < 3x-1 as it satisfies the inequality.
Hence, option C is true.
Step-by-step explanation:
Given the point (0, 0)
a)
Putting the point (0, 0) the inequality
y+4 < 3x-1
0+4 < 3(0)-1
4 < -1
This is false as -1 can not be greater than 4
b)
y-1 < 3x-4
Putting the point (0, 0) the inequality
0-1 < 3(0)-4
-1 < -4
This is false as -1 can not be lesser than -4
c)
y-4 < 3x-1
Putting the point (0, 0) the inequality
0-4 < 3(0)-1
-4 < -1
This is true as -4 is lesser than -1
d)
y+4 < 3x+1
Putting the point (0, 0) the inequality
0+4 < 3(0)+1
4 < 1
This is false as 4 can not be lesser than 1
Therefore, (0, 0) s the solution of y-4 < 3x-1 as it satisfies the inequality.
Hence, option C is true.
3) How many counting numbers less than 50 are multiples of both 3 and 5?
Answer: 3 numbers
Step-by-step explanation:
For this questions to be solved, we need to write the multiples of both 3 abd 5 that are less than 50. This will be:
Multiples of 3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48
Multiples of 5 = 5, 10, 15, 20, 25, 30, 35, 40, 45.
Common multiples = 15, 30 and 45
Therefore, the numbers that is less than 50 that are multiples of both 3 and 5 are 3 numbers

Translate the phrase into algebraic expression seven more than twice Jose’s height using the variable J to represent Jose height what would be the algebraic expression
Answer:
2j+7
Step-by-step explanation:
Phrase Into Algebraic Expression
If a problem is correctly phrased, it should be easily translated into algebraic language by following simple and concrete rules.
We have the phrase:
7 more than twice Jose's height.
Usually, we first deal with products and divisions before sums and subtractions because of the natural order of mathematic operations.
In the given phrase, the '7 more' part is left to the end and we start with the 'twice' part because it's a product.
Since we are using the variable j for Jose's height, then twice Jose's height is 2j.
Now we finish the expression by adding 7: 2j+7
Thus, the translation to algebraic expression is: 2j+7

Cheese pizza cost 6$ each and four topping pizza that cost $10 each. If you order c cheese pizzas and f four toppings how much would you pay
Answer:
[tex]Total = \$6c + \$10f[/tex]
Step-by-step explanation:
Given
[tex]Cheese\ Pizza = \$6[/tex]
[tex]Topping\ Pizza = \$10[/tex]
Required
Cost of c cheese and f topping pizza
Solving for c cheese pizza
If 1 cheese pizza costs $6,
c cheese pizza would cost $6 * c
Solving for f topping pizza
If 1 topping pizza costs $10,
f topping pizza would cost $10 * f
Hence:
[tex]Total = \$6 * c + \$10 * f[/tex]
[tex]Total = \$6c + \$10f[/tex]
Hence, the total amount paid is: [tex]\$6c + \$10f[/tex]

6. Given WY with W(3, 7) and Y(13, -8), if X
partitions WY such that the ratio of WX to XY
is 3:2, find the coordinates of X.
Answer:
(5, 1)
Step-by-step explanation:
Given the coordinates W(3, 7) and Y(13, -8) divided into the ratio 3:2
The midpoint formula is expressed as;
M(X, Y) = (ax1+bx2/a+b, ay1+by2/a+b)
a = 3,
b = 2
x1 = 3
y1 = 7
x2 = 13
y2 = -2
To get the coordinate of X
x = ax1+bx2/a+b
x = 3(3)+2(123/3+2
x = 9+26/5
x = 35/5
x= 7
y= ay1+by2/a+b
y = 3(7)+2(-8)/2+3
y = 21-16/5
y = 5/5
y = 1
Hence the coordinate of X is (x, y) = (5, 1)

Jason purchased a pack of game cards that was on sale for 13% off. The sales tax in his county is 8%. Let y represent the original price of the cards. Write an expression that can be used to determine the final cost of the cards.
Answer:
c = (y-0.13y)(1.08)
Step-by-step explanation:
c = cost and y = the original price
The amount of money off is 13% of y, or 0.13 of y. You would subtract that from y to get the price of the cards with the discount. For final cost, you need the cost of the cards (1) plus the cost of tax (8%, or 0.08). 1+0.08 is 1.08, so that's what you would multiply y by to get the final cost of the cards.

A kite is flying 99 ft off the ground, and it's string is pulled taut. The angle of elevation of the kite is 41°. Find the length of the string. Round your answer to the nearest tenth
Answer:
150.90 feet
Step-by-step explanation:
It is given that,
A kite is flying 99 ft off the ground
The angle of elevation is 41°.
We need to find the length of the string. Let it is H.
Here, 99 ft is the perpendicular of a right angled triangle. We need to find hypotenuse of the triangle. Using trigonometry we can find it as follows :
[tex]\sin\theta=\dfrac{P}{H}\\\\H=\dfrac{P}{\sin\theta}\\\\H=\dfrac{99}{\sin(41)}\\\\H=150.90\ \text{feet}[/tex]
So, the length of the string is 150.90 feet.
