Answer:
42
Step-by-step explanation:
The quadrilateral is a parallelogram
The area of a parallelogram can simply be calculated by multiplying the base length by the height
The parallelogram has a height of 3m and a base length of 4 + 10 = 14m
Hence area = 14 * 3 = 42

4
Step-by-step explanation:
x + x² = 20
x² + x - 20 = 0
Factor
(x + 5)(x - 4) = 0
x = {-5, 4}
-5 + 25 = 20

Draw and label the circle given by the equation (x - 5 + y + 10 = 6
Answer:
See attachment for drawing
Step-by-step explanation:
Given
[tex](x -5)^2 + (y + 10)^2 = 6^2[/tex]
Required
Draw and label the circle
The equation of a circle is:
[tex](x -a)^2 + (y - b)^2 = r^2[/tex]
Where:
[tex]Center = (a,b)[/tex]
[tex]Radius = r[/tex]
So, we have:
[tex]Center = (5,-10)[/tex]
[tex]Radius = 6[/tex]

______
Please help I can't figure it out
Answer:
61.2%
Step-by-step explanation:
Let's start by finding the total area of the circle
it says that the radius is 4 so the total area is 16π
Then let's find the area of the traingle
The hieght is 6.5 and the base is 6
.5*6.5*6=19.5
Let's then find the white area
16π-19.5=30.765
Finally we just have to do (30.765/16π)= 61.2%

Some lemon, lime, and cherry lollipops are placed in a bowl. Some have a
chocolate center, and some do not. Suppose one of the lollipops is chosen
randomly from all the lollipops in the bowl. According to the table below, if it
is known to be lime, what is the probability that it does not have a chocolate center?
Answer:
ok first we have to add the number of lollipops up
9+13+5+11+7+15=60
so there is 60 lollipops in total
now we have to add up the ones with out a chocolates center
11+7+15=33
so 33/60
we can simplify this
11/20
now we multiply both by 5
55/100
so 55%
Hope This Helps!!!
The correct answer is option A which is the probability of not having a chocolate center is 55%.
What is probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
The given data is:-
9+13+5+11+7+15=60
So there are 60 lollipops in total, now we have to add up the ones without a chocolate center.
The probability will be calculated as:-
11+7+15=33
P =33/60
P = 11 / 20
Now we multiply both by 5
P = 55/100
Therefore the correct answer is option A which is the probability of not having a chocolate center is 55%.

Solve the equation by factoring. 2x^2=8x
Answer:
x= 0 x=4
Step-by-step explanation:
2x^2=8x
Subtract 8x from each side
2x^2 -8x=8x-8x
2x^2 - 8x =0
Factor 2x
2x( x-4) =0
Using the zero product property
2x =0 x-4 =0
x= 0 x=4
Answer:
(0,4)
Step-by-step explanation:
Divide both sides of the equation by 2
x^2=4x
Move the variable to the left-hand side and change it's sign
x^2-4x=0
Factor out x from the expression
xx(x-4)=0
Separate into possible cases. )When the product of factors equals 0, at least one factor is 0)
x=0
x-4=0
solve the equation for x
x=0
x=4

how far does the train travel if it is doing 65km/h during a time of 95 minutes ? give your answer in kilometers and then in meters
9514 1404 393
Answer:
102 11/12 km ≈ 102.917 km
102,916 2/3 m ≈ 102,917 m
Step-by-step explanation:
1 minute is 1/60 of an hour, so 95 minutes is 95/60 hours = 19/12 hours.
Distance is the product of speed and time, so ...
distance = (65 km/h)(19/12 h) = 1235/12 km = 102 11/12 km ≈ 102.917 km
__
Each kilometer is 1000 meters, so this distance is ...
(102.917 km) × (1000 m/km) = 102,917 m

Hello,
h(x)=x²+1
k(x)=x-2
First of all, you must understand that:
(h+k)(x)=h(x)+k(x)
So, (h+k)(3)=h(3)+k(3)=(3²+1)+(3-2)=(9+1)+1=11
3h(2)+2k(3)=3*(2²+1)+2*(3-2)
=3*(4+1)+2*1

Noah invests $3,600 for two years.
The account pays 0.43% monthly compound interest. To the nearest cent, what's the total that will be in Noah's account after two years?
Answer:
Future value, A = $8444.16
Step-by-step explanation:
Given the following data;
Principal = $3,600
Time = 2 years
Number of times = 24
Interest rate = 0.43 %
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value. P is the principal or starting amount. r is annual interest rate. n is the number of times the interest is compounded in a year. t is the number of years for the compound interest.Substituting into the equation, we have;
[tex] A = 3600(1 + \frac{0.43}{24})^{24*2}[/tex]
[tex] A = 3600(1 + 0.01792)^{48}[/tex]
[tex] A = 3600(1.01792)^{48}[/tex]
[tex] A = 3600(2.3456)[/tex]
Future value, A = $8444.16
Why can the value of the variable a in the expression a + 2 be any number?
Why does the variable b in the equation 6 + 2 = 5 have only one value?
Please help
Answer:
(a) Because the expression is not an equation
(b) Because the expression is an equation
Step-by-step explanation:
Solving (a): a + 2
The above expression can assume any value for a because it is not an equation.
Take for instance:
a = 2;
[tex]a + 2 \to 2 + 2 = 4[/tex]
[tex]a =-4[/tex]
[tex]a + 2 \to -4 + 2 = -2[/tex]
The reason for this is because the expression is not an equation
Solving (b): [tex]b + 2 = 5[/tex]
The above expression can assume only value for b, and the value is:
[tex]b + 2 = 5[/tex]
[tex]b = 5-2[/tex]
[tex]b =3[/tex]
This means that only [tex]b =3[/tex] will make the equation true.
The reason for this is because the expression is an equation

Mariam and Sana are excited that a new store just opened in town! They go together the first day it opens! Each time Mariam goes to the store she plans to spend Rs. 30, and each time Sana goes to the store she plans to spend Rs. 50. A few weeks from now, Mariam and Sana are surprised to find out that they have spent the exact same total amount of money at the store. What is the least possible number of times that Mariam has been to the store? Just write the number.
Answer:
Mariam went to the store 5 times, while Sana went 3 times.
Step-by-step explanation:
Since Mariam and Sana are excited that a new store just opened in town, and they go together the first day it opens, and each time Mariam goes to the store she plans to spend Rs. 30, and each time Sana goes to the store she plans to spend Rs. 50, and a few weeks from now, Mariam and Sana are surprised to find out that they have spent the exact same total amount of money at the store, to determine what is the least possible number of times that Mariam has been to the store the following mathematical reasoning has to be done:
To know how many times Mariam went and how many times Sana went to the store, since she spends Rs. 30 and the other Rs. 50, and they have spent the same after a few weeks, it is through the search for the lower common multiple of both numbers.
Thus, the common multiple less than 30 and 50 is 150 (30 x 5 or 50 x 3). Therefore, Mariam went to the store 5 times, while Sana went 3 times.

A card is drawn from a well-shuffled deck of 52 cards. Find the probability of drawing a diamond or a spade.
Answer:
2/13
Step-by-step explanation:
For a deck of card
Total cards = 52
Total spade = 4
Total diamond = 4
pr(drawing a spade) = number of spade/total cards
pr(drawing a spade) = 4/52 = 1/13
pr(drawing a diamond) = 4/52 = 1/13
Pr(diamond or a spade) = 1/13 + 1/13 = 2/13
