Suppose Julie has already earned 36 points right and solve an addition equation to find the number of points he still needs to earn a pizza party
Answer:
[tex]50 = 36 + p[/tex]
Step-by-step explanation:
Given
[tex]Total = 50[/tex]
[tex]Points = 36[/tex]
See attachment
Required
Determine the additional points (p) needed
The total point equals the sum of the already earned point and the points needed.
i.e.
[tex]Total = Points + p[/tex]
Substitute values for Total and Points
[tex]50 = 36 + p[/tex]
Janelle makes a profit of 10% when she sells a bag for $900
i. What is the cost price? ii. find out how much she should have sold it for to make a profit of 15%
Answer:
i. 818.18
ii. 940.9
Step-by-step explanation:
SP = 900
or, CP + 10% of CP = 900
or, CP + 10/100 × CP = 900
or, 110CP = 90000
or, CP = 90000/110
CP = 818.18
for profit= 15%
SP = 9000/11 + 15% of 9000/11
= 940.9
The graph models the value of a vehicle over x years following its purchase for $25,000.
Which interpretation is correct?
(A) The asymptote indicates that the original value of the vehicle approached $25,000
(B) The point (40, 0) contains the x-intercept
(C) The line x=25,000 is an asymptote of the graph
(D)The line y=0 is an asymptote of the graph
Answer: it’s D. I took the test
The correct interpretation are,
The asymptote indicates that the original value of the vehicle approached $25,000
The line y=0 is an asymptote of the graph
Graph of function:From the given graph,
It is observed that graph is never intersect the x- axis. Therefore, x-axis will be the asymptote.
The equation of x- axis is y= 0.
Since at x= 0, the value of y = 25,000 , It means that the original value of the vehicle approached $25,000.
The x- intercept is the point where graph crosses the x-axis.

Rafael is cutting pieces of wood to make a triangular pyramid like the one shown below. The base of the pyramid is an equilateral triangle, and the faces are isosceles triangles.
Answer:
[tex]Total = 32.4in^2[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
The surface area of the pyramid
To do this, we calculate the surface area of each of the pyramid faces.
For the equilateral triangle.
[tex]Base = 4.5in[/tex]
[tex]Height = 3.9in[/tex]
The area is:
[tex]A_1 = 0.5 * Base * Height[/tex]
[tex]A_1 = 0.5 * 4.5in * 3.9in[/tex]
[tex]A_1 = 8.775in^2[/tex]
There are 3 isosceles triangles of equal dimension.
[tex]Base = 4.5in[/tex]
[tex]Height = 3.5in[/tex]
The area of one of them is:
[tex]A_2 = 0.5 * 4.5in * 3.5in[/tex]
[tex]A_2 = 7.875in^2[/tex]
For the 3, the surface area is:
[tex]3A_2 = 7.875in^2 * 3[/tex]
[tex]3A_2 = 23.625in^2\\[/tex]

A. 3 and 4
B. 5 and 5
C. 7 and 24
D. 10 and 15 ( No links)
The measure of lengths of the legs are 7 and 24. Therefore, option C is the correct answer.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given that, the hypotenuse of a right triangle measures 25.
A) 3²+4²= Square of the hypotenuse
25=Square of the hypotenuse
Hypotenuse=5 units
B) 5²+5²= Square of the hypotenuse
50=Square of the hypotenuse
Hypotenuse=5√2 units
C) 7²+24²= Square of the hypotenuse
625=Square of the hypotenuse
Hypotenuse=25 units
D) 10²+15²= Square of the hypotenuse
325=Square of the hypotenuse
Hypotenuse=√325 units

What is the volume?The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.
The volume of the cuboid is,
Volume = (2¹/₆ x 1¹/₆ x 1 )
Volume = ( 13 / 6 ) x ( 7 / 6)
Volume = 91 / 36
The volume of a small cube is:-
Volume = (1/6) x (1/6)
Volume = 1/216
The number of cubes is,
Number = (91/36) ÷ (1/216)
Number = (91 x 216) / 36
Number = 546

A contractor digs a rectangular hole for the basements of a new house that is 10 1/2 feet deep. What is the width of the hole if 6,510 cubic feet of dirt are removed?
Answer:
w = 2√155 ft ✅
Step-by-step explanation:
Given that:
depth (d) = 10½ ft
Volume (v) = 6,510 ft³
Find the width (w) of the hole!
If the base is a square, then
the width and the length of the base is 'equal', so the
Volume of a cuboid =
V = w²d
width = square root of the division of volume by depth
w = √(V/d)
w = √(6,510/10½)
w = √620
w = √(4×155)
w = 2√155 ft ✅

What is expression?Expression is a combination of numbers, fraction, symbols, indeterminants, determinants,etc. It shows a relationship between two or more variables. It is mostly not found in equal to form.
How to find perimeter?We have been given that width be w, so the length will be 2w+5/2.
We know that perimeter of rectangle is 2(l+b)
Perimeter=2(2w+5/2+w)

A bag contains 5 white marbles and 30 blue marbles. If a representative sample contains 2 white marbles, then how many blue marbles would you expect it to contain? Explain. Because the ratio of white marbles to blue marbles is ▼ 6:5 6:1 5:6 1:6 in the population, the expected number of blue marbles is nothing times the number of white marbles in the representative sample. There should be nothing blue marbles.
Answer:
6:1
Step-by-step explanation:
Answer: 10
Step-by-step explanation:
The expected number of blue marbles in the representative sample is 10. This is because the ratio of white marbles to blue marbles in the population is 5:6, so for every 5 white marbles there are 6 blue marbles. Since the representative sample contains 2 white marbles, the expected number of blue marbles should be 6 times the number of white marbles, or 6 x 2 = 10.
Joe runs an M&M's factory and is reviewing the bagging machines. They drop M&M's into bags on a conveyor belt, with 39 M&M's going into each bag. Write an equation for the number of bags 'B' that can be filled from a supply of M&M's 'T'. Write your equation in the form of B=_____________.
The equation for the number of bags 'B' that can be filled from a supply of M&M's 'T' will be T / 39.
How to explain the equationThe formula to determine how many bags 'B' can be filled with M&M's from a stockpile of 'T', where each bag contains 39 candies, is:
B = T/39
This computation takes the sum of all M&M's in 'T' and divides it by the quantity of candies present in each sack (39), producing the amount of bags 'B' that can be filled.
