Answer:
x = 14 and y = 10
Step-by-step explanation:
TRANSLATING WORDS INTO EQUATIONS:
Let the two numbers be x and y
"The sum of two numbers is 24" translate as x + y = 24
"Their difference is 4" translates as x-y=4
Those two equations make up the system of linear equations
SOLVING BY ELIMINATION:
Adding the two equations, we get
x + y + x - y = 24 + 4
2x = 28
x = 28 / 2
x = 14
substituting that into x + y = 24 we get
14 + y = 24
y = 24 - 14
y = 10

What is the equation of the line that passes through the point (6,6) and has a slope of 5/3??
Answer:
y = 5/3x - 4
Step-by-step explanation:
(6, 6)
m = 5/3
Slope-intercept:
y - y1 = m(x - x1)
y - 6 = 5/3(x - 6)
y - 6 = 5/3x - 10
y = 5/3x - 10 + 6
y = 5/3x - 4
The solids are similar. Find the volume V of the red solid.
Answer:
13,564.8
Step-by-step explanation:
The ratio of the volumes of similar solids is the cube of the scale factor.
Scale factor:
red solid : blue solid = 12/10 = 6/5
Ratio of volumes:
volume red solid : volume blue solid = (6/5)^3
volume of red solid = 7850 ft^3 * (6/5)^3 = 13,564.8 ft^3
Answer: V = 13,564.8 ft^3
Given the sequence 9,6,3,0,..., at what nth term will the number become -24?
Answer:
12
Step-by-step explanation:
A sequence is given and we need to find the term when it will become -24 . The given sequence is,
9 , 6 , 3 ,0 , . . . . .
Here Common Difference can be calculated by subtracting consecutive terms . So the Common Difference is 6-9 = -3 . Here the nth term is (-24) .Now using the formula to find nth term .
⇒ T_n = a + (n-1)d
⇒ (-24) = 9 + (n-1)(-3)
⇒ -24-9 = (n-1)(-3)
⇒ (n-1) = -33/-3
⇒ n-1 = 11
⇒ n = 11 + 1
⇒ n = 12
Hence the required number of term is 12.PWEASE HELP I DON'T UNDERSTAND THIS

Jennifer's grandma bought her a $50 savings bond when she was born. When Jennifer is 30 years old, the bond will have earned 110% in interest. How much will the bond be worth when Jennifer is 30 years old?
Answer:
105$
Step-by-step explanation:
We are told that she starts with 50$
We are also that after 30 years she earns 110% on interest
Given this information we need to find the value of the bond after the 30 years
To do so we take 110% of the initial value (50$) and add that to the initial value
So the answer = 110%(50) + 50
110%*50=55
55+50=105
So in 30 years the bond will be worth 105$

Lisa rolls a number cube that has sides labeled 1 to 6 and then flips a coin. What is the probability that she rolls an odd number and flips tails?
A.1/8
B.1/4
C.1/2
D.3/4
Answer: B. 1/4
Step-by-step explanation: The probability of rolling an odd number is 3/6 since there are 3 odd numbers between 1 and 6 (1, 3, 5). The probability of flipping a coin and getting tails is 1/2 since you can either get heads or tails. With this knowledge, you must multiply these two probabilities to get the probability of getting an odd number AND tails; so, 3/6 x 1/2 = 3/12 = 1/4.

Ava's watering can holds 2 liters of
water. She uses 200 milliliters to
water each of her plants. How many
plants can she water if she use the
entire watering can? (uh i’m about to get 0 )
Answer:
2,000 m (2 Liters) = 100 plants
Step-by-step explanation:
2,000 milliliters make up 2 liters.
200 liters are being poured.
2,000/200 = 10
10 plants are being watered each time.
200 m = 10 plants
400 m = 20 plants
600 m = 30 plants
800 m = 40 plants
1,000 m = 50 plants
1,200 m = 60 plants
1,400 m = 70 plants
1,600 m = 80 plants
1,800 m = 90 plants
2,000 m = 100 plants

Kurt and Maria's high school is having a newspaper drive.The goal is to collect 3,585 pounds of newspapers. So far, 21% of the goal has been reached. Kurt estimated the number of pounds of newspapers collected by finding 10% of 3,600 and then multiplying the result by 2. Maria estimated the number of pounds of newspapers collected by finding One-fifth of 3,600.
Options:
Who is right, and why?
a. Neither Kurt nor Maria is right, because 3,500 should be used instead of 3,600.
b. Kurt is right, because finding 1/5 of 3,600 is not a good way to approximate 21% of 3,585.
c. Maria is right, because finding 10% of 3,600 and multiplying the result by 2 is not a good way to approximate 21% of 3,585.
d. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.
Answer:
d. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.
Step-by-step explanation:
Given
[tex]Goal = 3585[/tex]
[tex]Collected = 21\%[/tex]
[tex]Kurt= 10\% * 3600 * 2[/tex]
[tex]Maria = \frac{1}{5} * 3600[/tex]
Required [Missing from the question]
Who is correct and why?
First, we calculate the actual amount collected.
[tex]Actual = Collected * Goal[/tex]
[tex]Actual = 21\% * 3585[/tex]
[tex]Actual = 752.85[/tex]
[tex]Actual = 753[/tex] --- approximate
Next, determine the estimate (round 3585 to 3600 and 21% to 20%)
[tex]Estimate = 20\% * 3600[/tex]
[tex]Estimate = 720[/tex]
Next, calculate Kurt and Maria's estimates
[tex]Kurt= 10\% * 3600 * 2[/tex]
[tex]Kurt = 720[/tex]
[tex]Maria = \frac{1}{5} * 3600[/tex]
[tex]Maria = 720[/tex]
Hence, Kurt and Maria are correct because of option (d)

Set 1
first of all we have to look at the negative numbers:
-99% = -0,99
-√80 = is almost 9
so :
-9,(9) ; -√80 ; -99%
then the positive numbers:
19% = 0,19
√9 = 3
1/9 = 0,11...
so
1/9 ; 19% ; √9
final answer:
-9,(9) ; -√80 ; -99% ; 1/9 ; 19%, √9
Set 2
descending order = from greatest to least
In this case we have to look at first at positive numbers
2/3 = 0,6
√23 = 4,...
20/3 = 6,...
23% = 0,23
so
20/3 ; √23 ; 2/3 ; 23%
negative numbers
-√34 = -5,...
so :
-4,(3) ; -√34
final answer:
20/3 ; √23 ; 2/3 ; 23% ; -4,(3) ; -√34

6m - 8 = 1/2(-4m + 16)
Answer:
m=2
Step-by-step explanation:
6m - 8 = 1/2(-4m + 16)
Distribute
6m -8 = -2m +8
Add 2m to each side
6m-8+2m = -2m +8+2m
8m -8 = 8
Add 8 to each side
8m-8+8 = 8+8
8m = 16
Divide each side by 8
8m/8 = 16/8

44 is r% of 16 what is r
Answer:
r= 275
Step-by-step explanation:
Let's write an equation with the given information.
44= r% ×16
Rewrite the percentage as a fraction:
[tex]44 = \frac{r}{100} \times 16[/tex]
Divide both sides by 16:
[tex] \frac{r}{100} = 44 \div 16[/tex]
[tex] \frac{r}{100} = 2.75[/tex]
Multiply both sides by 100:
r= 2.75(100)
r= 275

Trent attaches his A+ test to the refrigerator with a circular magnet. Out of curiosity, he measures the magnet and calculates that it has a diameter of 4 centimeters. What is the magnet's area?
Answer:
12.6 cm²
Step-by-step explanation:
From the above question, the magnet is circular in shape
The area of a circle is given as:
= πr²
The area of the magnet = π × r²
Diameter = 4cm
r = Diameter/2 = 4cm/2 = 2cm
= π × (2cm)²
= 12.566370614cm²
Approximately = 12.6 cm²
The area of the magnet = 12.6cm²
