Answer:
150 feet
Step-by-step explanation:
A rectangle has 2 pairs of equal sides.
One of the sides is 100 feet, meaning another side is 100 feet.
If we subtract 200 feet we are left with 300, which are the last two sides.
Divide 300 by 2 to get each side length.
150 feet
What number is halfway between 0 and negative 20
Ryan must read 150 pages for school tomorrow.
It took him 30 minutes to read the first 20 of
the assigned pages. At this rate, how much
additional time will it take him to finish
the reading?
Ryan has 130 pages left to read (150 − 20).
He read 20 pages in 30 minutes, which means he read at a rate of 40 pages per 1 hour.
To find out how much longer it will take him to finish the assignment, divide the total number of pages remaining (130) by the number of pages he is able to read per hour (40):
[tex]\frac{130}{40}= 3\frac{1}{4}[/tex]_________Ryan spent 30 minutes reading, so he will need 225 - 30 = 195 minutes to finish reading.
Here's the solution:
If it took Ryan 30 minutes to read 20 pages, then it will take him 30/20 = 1.5 minutes to read 1 page.
To read 150 pages, it will take him 1.5 × 150 = 225 minutes.
He already spent 30 minutes reading, so he will need 225 - 30 = 195 minutes to finish reading.
So the answer is 195

Answer:
✔ inverses
✔ (y, x)
Step-by-step explanation:
The tables show that the two functions are inverses because the ordered pair (x, y) for one function is the ordered pair (y, x) for the other function.
How do you know if functions are inverses?Permit f be a characteristic. If any horizontal line intersects the graph of f more than as soon as, then f does now not have an inverse. If no horizontal line intersects the graph of f extra than once, then f does have an inverse.
Does every function have an inverse?No longer do all capabilities have inverses. people who do are known as "inverse." learn the way we can tell whether or not a function is inverse or now not. Inverse functions, inside the maximum preferred sense, are features that "reverse" every difference.

QUESTION 1
Employees in 2018 paid 5.2% of their gross wages toward social security while employers paid another
7.3% How much will a person's employer pay towards social security if an employee makes $50,000 in
the year.
Answer:
$2600
Step-by-step explanation:
Given that:
the employee earns $50,000 in a year
The amount of money on wages paid by the employee towards social security = 5.2% of their gross wage
= [tex]\dfrac{ 5.2 \times 50000}{100}[/tex]
= $2600
if an employee makes $50,000 in the year, he will pay $2600 towards social security.
The other employees that paid 7.3% of their gross wages will not be regarded since they're paying it from their own fund.

A store had received a supply of 8
dozen calculators and sold them for
$9.99 each. if the store sold all but 2
dozen of the calculators, approximately how
much money did it make?
Answer:
1 dozen = 12 calculators
8 dozen = 12 * 8 = 96 calculators
2 dozen = 12 * 2 = 24 calculators
96 - 24 = 72 calculators
*each was sold for $9.99 so:
72 * $9.99 = $719.28 which rounds to $719

Solve the following triangle completely.
(a). in triangle ABC, B = 25.6° C = 124.4° C= 39.2m
(b) B = 101.15°, b= 17.23cm and C= 10.86cm.
Answer:
The answers is below in bold.
Step-by-step explanation:
(a) A = 180 - 25.6 - 124.4 = 30 degrees.
Next use the Sine Rule:
b / sin B = c / sin C
b / sin 25.6 = 39.2/sin 124.4
b = (39.2 * sin 25.6) / sin 124.4
b = 20.53 m.
Also
a / sin A = c / sin C
a / sin 30 = 39.2 / sin 124.4
a = (39.2 * sin 30 / sin 124.4
a = 23.75 m.
b). This is solved in a similar way to (a).
First find angle C using the sine rule.
Then you will know angle A from the 180 degree Rule.
Then you can find the length of a using the Sine Rule.

The cost in dollars of making x items is given by the function C(x)=10x+800. a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item. Fixed cost =$ Number b. What is the cost of making 25 items? C(25)=$ Number c. Suppose the maximum cost allowed is $2300. What are the domain and range of the cost function, C(x)? When you enter a number in your answer, do not enter any commas in that number. In other words if you want to enter one thousand, then type in 1000 and not 1,000. It's not possible to understand what the interval (1,000,2,000) means, so you should write that as (1000,2000). Domain: Preview Range: Preview
Answer:
a). Fixed cost = $800
b). The cost for 25 items is $1050
c).Range = 150
Domain g(x) = 150
Step-by-step explanation:
The cost in dollars of making x item is given by the function C(x)=10x+800.
The fixed cost is when x= 0
Fixed cost
C(0)= 10(0) +800
C(0) = 0+800
C(0)= 800
Fixed cost = $800
The cost for 25 items
C(25) = 10(25)+800
C(25) = 250+800
C(25) = 1050
The cost for 25 items is $1050
If Maximum cost=$2300
C(x)=10(x) +800= 2300
Range of x
10(x) = 2300-800
10(x) = 1500
X= 1500/10
X= 150
Range = 150
Domain g(x) = 150

A diver descended at a rate of 18 feet per second. What was her depth after one minute?
Answer:
1,080 ft
Step-by-step explanation:
Rate of descending or travel (r) = 18 ft per second.
The depth or distance traveled/descended (d) after 1 minute can be calculated as follows:
[tex] d = r*t [/tex]
r = 18ft/sec
t = 1 min = 60 secs
[tex] d = \frac{18 ft}{1 sec}*60secs [/tex]
[tex] d = 18ft*60 [/tex]
[tex] d = 1,080 ft [/tex]

Answer:
Total distance covered each week is [tex]11\frac{1}{4}\ miles[/tex]
Step-by-step explanation:
Given
Days = 5 days
Distance = [tex]2\frac{1}{4}[/tex] miles
Required
Determine the total distance covered in a week
To do this, we simply multiply distance by number of days.
[tex]Total\ distance = distance * days[/tex]
[tex]Total\ distance = 2\frac{1}{4} * 5[/tex]
Convert to improper fraction
[tex]Total\ distance = \frac{9}{4} * 5[/tex]
[tex]Total\ distance = \frac{9 * 5}{4}[/tex]
[tex]Total\ distance = \frac{45}{4}[/tex]
[tex]Total\ distance = 11\frac{1}{4}[/tex]
Hence, the total distance covered each week is [tex]11\frac{1}{4}\ miles[/tex]

If DF =9x-39, find EF
Answer:
EF = 58
Step-by-step explanation:
From the question given, we obtained the following information:
DF = 9x – 39
DE = 47
EF = 3x + 10
EF =?
We'll begin by calculating the value of x.
This can be obtained as follow:
DF = DE + EF
DF = 9x – 39
DE = 47
EF = 3x + 10
DF = DE + EF
9x – 39 = 47 + 3x + 10
9x – 39 = 47 + 10 + 3x
9x – 39 = 57 + 3x
Collect like terms
9x – 3x = 57 + 39
6x = 96
Divide both side by 6
x = 96/6
x = 16
Finally, we shall determine the value of EF as follow:
EF =?
x = 16
EF = 3x + 10
EF = 3(16) + 10
EF = 48 + 10
EF = 58

Answer:
x = -7
Step-by-step explanation:
4 ( 2x+14) =0
Divide by 4
2x+14 = 0
Subtract 14 from each side
2x = -14
Divide by 2
2x/2 = -14/2
x = -7
Answer:
x = -7
Step-by-step explanation:
Apply the distributed property by multiplying 2x by 4 and 14 by 4, and then adding them together, so it now looks like this: 8x + 56 = 0Subtract 56 from each side of the equation, so it now looks like this: 8x = -56Divide each side by 8 to cancel out the 8 next to x. It should now look like this: x = -7Therefore, x is equals -7.

Si yo tengo una canasta llena de mangos y piñas, de las cuales hay 30
mangos y 20 piñas ¿Qué fruta es más probable que saque al azar de la
canasta?
Respuesta: Es más probable sacar un mango.
Explicación:
La probabilidad se refiere a la posibilidad de que un evento occura y no otro. En el caso que se describe, la probabilidad de sacar cada fruta puede ser calculada dividiendo el total de cada fruta en el número de frutas totales:
Probabilidad de sacar un mango:
[tex]\frac{cantidad de mangos}{cantidad de frutas en la canasta}[/tex] = [tex]\frac{30}{50}[/tex] =[tex]0.6[/tex]
Probabilidad de sacar una piña:
[tex]\frac{cantidad de pinas}{cantidad de frutas en la canasta} = \frac{20}{50}[/tex] [tex]= 0.4[/tex]
De acuerdo a lo anterior la probabilidad de sacar un mango es de 0.6 o de 60% (multiplica la probabilidad por 100 para saber su equivalente en porcentaje), mientras que la probabilidad de sacar un mango es de 0.4 o 40% lo cual es mucho más bajo. Es decir que es más probable sacar un mango.
