Answer:
1.) 15-3-2=x
2.) He can buy 3 sodas
Step-by-step explanation:
1.) 15 is how much he has, -3 is the price of the popcorn, -2is the price of the soda. =x is what needs to be solved in the equation (its 10 if you need the answer)
2.) He can buy 3 sodas because 3 boxes of popcorn is $9 since one box is $3, he has $15 you take away $9 and you are left with $6 and 6 divided by 2 is 3.
Jaden places potatoes with a mass of 0.55 kilograms on a grocer's scale. The spring is displaced by 1.2 centimeters. He then places some onions on the scale that displace the spring by 0.67 cm. What is the mass of the onions (1 kg=9.8 N)? 5.39 kg 3.01 kg 0.67 kg 0.31 kg
Answer:
.31 kg
Step-by-step explanation:
F=kx
F = the force of the spring
k = the spring constant
x = the spring displacement (stretch or compression)
we also know that 1 kg = 9.8 N which also means that 9.8(kg)=F
let's first find the force of the first problem, which is .55 kg. Using the formula 9.8(kg)=F we can do 9.8(.55)=F which would mean the force is 5.39 N
so 5.39=k(1.2 centimeters)
Now we need to convert centimeters to meters. This would make 1.2 into .012m. Now our problem is 5.39=k(.012)
divide 5.39 by .012 to get 449.17
our k is 449.17
Now for our problem, we are going to find the mass.
Do this by putting what we already know into the problem.
F=449.17(.67 centimeters)
Now we already know we need to convert centimeters to meters which will make our formula F=449.17(.0067m)
This will result in F=3.01 but the problem is asking for mass, not force.
Use the formula 9.8(kg)=F
9.8(kg)=3.01
kg=.31
solution: .31 kg

$23.75 for a box of cereal and 4 identical loaves of bread.
If the cereal costs
$5.75, which equation can be used to find the cost of a single loaf of bread?
Answer:
The way you can find the cost of just one loaf of bread is by taking the amount charged and then dividing it by 4 and then you would get your answer of $5.93

Trucks must haul between 150,000 yd' and 180,000 yd of earth each day to create a new
water park near Universal Studios in Orlando, Florida. The trucks can haul 10.000 yd per day
and 120,500 yds have already been brought to the site. How many days are needed to
complete this job?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Range which must be hauled by trucks :
150,000 - 180,000 yds of earth
Haul per day = 10000 yds
Already removed = 120,500
We can express the problem as an inequality:
Using y = number of days
150,000 ≤ (10000y + 120,500) ≤ 180000
150,000 ≤ (10000y + 120,500)
150000 - 120500 ≤ 10000y
29500/10000
y = 2.95 days
10000y + 120,500 ≤ 160000
10000y ≤ 160000 - 120500
y = 39500/10000
y = 3.95
2.95 ≤ y ≤ 3.95

D) Endpoints
Answer: D
Step-by-step explanation:
A line segment is defined as a part of a straight line connecting two points called the endpoints, option D.
---------------------------------
A line segment is a straight line that connects two points.These two points are the extremes of the line segment, that is, the start and the finish, and thus, are called endpoints.This means that the correct option is given by D.For more on line segments and endpoints, you can check a similar problem at https://brainly.com/question/24778489
On a number line, the coordinates of X, Y, Z. and Ware-7. -5.2, and 4, respectively. Find the lengths of the two segments below. Then tell whether they are congruent.
XY and ZW
The length of XY is (Type an integer or a decimal.)
The length of ZW is (Type an integer or a decimal)
Answer:
[tex]XY = 2[/tex]
[tex]ZW = 2[/tex]
XY and ZW are congruent
Step-by-step explanation:
Given
[tex]X = -7[/tex]
[tex]Y = -5[/tex]
[tex]Z = 2[/tex]
[tex]W = 4[/tex]
Distance XY is calculated as thus:
[tex]XY = |X - Y|[/tex]
[tex]XY = |-7 - (-5)|[/tex]
[tex]XY = |-7 + 5|[/tex]
[tex]XY = |-2|[/tex]
[tex]XY = 2[/tex]
Distance ZW is calculated as thus:
[tex]ZW = |Z - W|[/tex]
[tex]ZW = |2 - 4|[/tex]
[tex]ZW = |-2|[/tex]
[tex]ZW = 2[/tex]
[tex]XY = ZW = 2[/tex]
Hence:
XY and ZW are congruent

Which equation does the graph below represent
Answer: The answer is y=-3x
Step-by-step explanation: You can see in the picture that the line is going down which represents a negative slope so you can eliminate C and D. Now you are left with A and B. 1 unit up is equal to 3 so the rise over run is -3/1 and that translates to Y=-3x answer B

Joshua's cousin pledged $12 for a charity walk. If Joshua walked 3 miles, how much did his cousin pay per mile?
Answer:
$4
Step-by-step explanation:
URGENT: Figure C and figure E shown on the coordinate plane blow a transformation was performed on figure C to create figure D. Then, a transformation was performed on figure D to create figure E
As a result of the series of transformation performed, figure C is similar figure E, however these figures are not congruent
1• justify why figures C And E are similar and not congruent
2• describe a transformation applied to figure C that will create figure D and then a transformation performed on figure D that will create Figure E
Answer:
1. Whereby one square = One unit, we have;
Lengths of the sides of figure C are;
4, √(4² + 2²), √(4² + 2²) which simplifies to 4, 2·√5, 2·√5
Lengths of the sides of figure E are;
2, √(1² + 2²), √(1² + 2²) which simplifies to 2, √5, √5
Figure E is equivalent to figure C scaled down by a factor of 1/2
The trigonometric ratios of the two figures are therefore equal and figure C is similar to figure E but figure C is larger than figure E
2. A transformation that will create figure D from figure C is a rotation, 90° counter clockwise about the point (2, -2)
A transformation that will create figure E from figure D is a dilation of figure D by 1/2 with the midpoint of figure D being the center of dilation
