A pizza buffet has prepared 18 pizzas to place on the line at the beginning of lunch at 11:00 a.M. The equation y 14x + 18 can be used to describe the total number of pizzas that have been placed out on the buffet line, where x represents every 9 minutes after 11:00 a.M. Which statement best describes the rate of change in the number of pizzas set out on the buffet?
Answer: b. Every 18 minutes, 28 more pizzas were set out on the buffet.
Step-by-step explanation:
The equation is in the form: y = mx + c
m is the gradient which represents the rate of change per a given value of x.
x here is every 9 minutes after 11:00. Every 18 minutes therefore will give x a value of 2 because 18/9 = 2.
The rate of change every 18 minutes is therefore;
= 14 * 2
= 28 pizzas

There are 3 green and 5 red jelly beans in a stocking. You randomly choose one of the jelly beans. What is the probability of selecting a red jelly bean?
Answer: 5/8
Step-by-step explanation:
Number of green jelly beans = 3
Number of red jelly beans = 5
Total number of jelly beans = 3 + 5 = 8
The probability of selecting a red jelly bean would be:
= Number of red jelly beans /:Total number of jelly beans
= 5/8

How many years, to the nearest tenth, will be needed for $5000 to increase to $18000 at 3.0% annual interest compounded
Complete question :
How many years, to the nearest tenth, will be needed for $5000 to increase to $18000 at 3.0% annual interest compounded monthly
Answer:
Step-by-step explanation:
Initial amount (P) = 5000
Final amount (A) = 18000
Interest rate (r) = 3% = 0.03 compounded monthly
A = P(1 + r/n)^nt
n = number of compounding timea per period
18000 = 5000(1 + 0.03 / 12)^12t
18000 / 5000 = (1 + 0.0025)^12t
3.6 = (1 + 0.0025)^12t
3.6 = 1.0025^12t
Take the In of both sides
1.2809338 = 1.03t
t = 1.2809338 / 1.03
solve. show all work please.
Answer:
8 hours
Step-by-step explanation:
In the problem, it gives you the formula: d=rt, and in the rest of the problem it gives you the distance and the rate, so all you have to do is plug the numbers in and solve.
360m = 45mph(t)
Isolate the variable by dividing 360 by 45
360/45 = t
8 = t
This means that it will take 8 hours to travel 360 miles at a rate of 45 miles per hour.

An electric heater uses 7 1/2 units of electricity in 3 hours. How many units does it use in 5 hours?
Answer:
12.5 units or 12 1/2 units
Step-by-step explanation:
From the question, it uses 7.5 units in 3 hours.
In one hour it will use; 7.5/3 = 2.5 units
If 2.5 units is used in 1 hour
In 5 hours; 5 × 2.5 units will be used. This gives us 12.5 units or 12 1/2 units.
Find the unit rate.
Round to the nearest hundredth, if necessary.

Which equation has a solution of X=
13?
O
X+ 3 = 10
O x-10=3
* = 26
Ox+12= 1
Answer:
x-10=3
x+10-10=3+10
x=13
Answer:
x - 10 = 3
Step-by-step explanation:
x - 10 = 3
Add 10 to both sides
x - 10 + 10 = 3 + 10
x = 13

HOPE IT HELPS YOUFind the value of each variable 16-21
Answer:
16. [tex]x = 80^\circ[/tex]
17. [tex]x = 55, y =70, z = 55[/tex]
18. [tex]x =8, y =3[/tex]
19. [tex]r = 66^\circ[/tex], [tex]t = 73^\circ[/tex]
20. [tex]y = 70^\circ, x = 55^\circ[/tex]
21. [tex]x =56^\circ, y = 62^\circ[/tex]
Step-by-step explanation:
16. Side [tex]AB = AC[/tex]
So, the opposite angles of the triangle will also be equal.
[tex]\angle B =\angle C = 50^\circ[/tex]
Using triangle sum property, angle of all the internal angles of a triangle is equal to [tex]180^\circ[/tex].
[tex]50+50+x = 180\\\Rightarrow x = \bold{80^\circ}[/tex]
17. Two sides are given as equal, [tex]x = z[/tex]
Angles on a straight line are always equal to [tex]180^\circ[/tex].
So,
[tex]x + 125 = 180\\\Rightarrow x = 55[/tex]
[tex]z = 55[/tex]
Using triangle sum property, angle of all the internal angles of a triangle is equal to [tex]180^\circ[/tex].
[tex]55+55+y = 180\\\Rightarrow y = \bold{70^\circ}[/tex]
18. All the angles are given equal to each other, therefore all the sides of the triangle will also be equal to each other.
[tex]4x+7 = 13y =39[/tex]
[tex]13y = 39\\\Rightarrow y = 3[/tex]
[tex]4x +7 = 39\\\Rightarrow 4x = 32\\\Rightarrow x = 8[/tex]
19. Two sides are given equal to each other, therefore angles opposite to them will be equal.
Using the triangle sum property in the left triangle:
[tex]r + 57 + 57 = 180\\\Rightarrow r = 66^\circ[/tex]
Using the property that vertically opposite angles are equal and the triangle sum property in the right triangle.
[tex]t+50+57 = 180 \\\Rightarrow t = 73^\circ[/tex]
20. All the sides are given equal to each other.
So, all the angles will be equal to [tex]60^\circ[/tex].
[tex]y - 10 = 60\\\Rightarrow y = 70^\circ[/tex]
[tex]x+5=60\\\Rightarrow x = 55^\circ[/tex]
21. Angles on a straight line are always equal to [tex]180^\circ[/tex].
Angles opposite to equal sides in a triangle are also equal.
[tex]118 + y = 180\\\Rightarrow y = 62^\circ[/tex]
Using triangle sum property:
[tex]x+2y = 180\\\Rightarrow x = 180 - 124 = \bold{56^\circ}[/tex]
Write 2 cents using the dollar symbol (without spaces)
Answer:
$0.02
Step-by-step explanation:
This is the correct way to do 2 cents. Since two is not in the tenths place, and is not yet a dollar, the correct answer is $0.02.
Hope this helps! :D
The representation of 2 cents in dollar sign will be $0.02.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
It is known that,
$1 = 100 cents
Divide both sides by 100
$1/100 = 1 cents
Multiply by 2 on both sides,
$(1/100)2 = 2 cents
$0.02 = 2 cents
Hence "The representation of 2 cents in dollar sign will be $0.02".

Which expression can be modeled using the number line?
Answer:
Expression that can be modeled using the number line is 7 over 10 divided by 1 over 10
Step-by-step explanation:
Arrow starts from 0 then it goes to 1/10 then to 2/10 then to 3/10 then to 4/10 then to 5/10 then to 6/10 then to 7/10.
Which implies 7/10 is divided into 7 equal parts of the equal length of 1/10 units.
