Write down the 3rd term in the sequence given by: T(n) = 2n² + n
Answer:
T(3) = 21
Step-by-step explanation:
To find the third term, substitute n = 3 into T(n) , that is
T(3) = 2(3)² + 3 = 2(9) + 3 = 18 + 3 = 21

Which ratio expresses the scale used to create this drawing? The post office has dimensions of 36 meters by 90 meters. A. B. C. D.
Answer:
2 : 5
Step-by-step explanation:
In order to obtain the ratio between numbers, we divide by the largest common factor between both.
In this question, the numbers are;
36 : 90
The largest common faction is 18. Dividing both numbers by 18, we have;
36 / 18 : 90 / 18
2 : 5
The ratio is; 2 : 5
whats the equation to (4,5) , Slope = 5/2
Answer:
y= 5/2x - 5
Step-by-step explanation:
First, use the equation y=mx+b
m = the slope (5/2)
x = the x coordinate: 4
y = the y coordinate: 5
Then plug in for the values and solve for the only unknown, b.
Therefore we have:
5 = (5/2)4 + b
5 = 10 + b
5 - 10 = b
b = -5
Revert to original equation:
y = 5/2x - 5

On a Map, 1 inch equals 48 miles. If the if the distance between two cities on a map is 2.5 inches how many miles apart are they
PLEASE HELP IM GONNA FAIL WILL GIVE BRAINLESS
Answer:
120
Step-by-step explanation:
first, divide 48 by 2 since its 2.5. since theres a half. then you do 48+48+24. you double 48 and then add the half(which is 24) and that equals 120
hope this helpsss
How would you show a rate of change of
60 miles per hour on a graph? Name
some of the points.
Answer:
You would show it by creating a XY graph and labelling the Y axis as the hours and the X axis as the distance. Some points are (1,60), (2,120), and (3,180).

Select all the ordered pairs that satisfy the function y = 3x + 5. A. (2, –1) A. , (2, –1) B. ( –3, –4) B. , ( –3, –4) C. ( 4, 17 ) C. , ( 4, 17 ) D. ( 3, 8 ) D. , ( 3, 8 )
Answer:
B. ( –3, –4)
C. ( 4, 17 )
Step-by-step explanation:
Function: y = 3x + 5
Using method of elimination
A. (2, –1)
x = 2, y = -1
-1 = 3 (2) + 5
-1 ≠ 11
This option is incorrect!
B. ( –3, –4)
x = -3, y = -4
-4 = 3 (-3) + 5
-4 = - 9 + 5
-4 = -4
This option is correct!
C. ( 4, 17 )
x = 4, y = 17
17 = 3 (4) + 5
17 = 12 + 5
17 = 17
This option is correct!
D. ( 3, 8 )
x = 3, y = 8
8 = 3 (3) + 5
8 = 9 + 5
8 = 14
This option is incorrect!
Underline the prepositions in the sentences. 1. The bus shuttles between Delhi and Gurgaon. 2. The children ran across the bridge. 3. Towards evening, you can hear the frogs croak. 4. I dug the flowerbeds with a spade. 5. The mountaineer reached the peak with great difficulty.
Answer:
1. The bus shuttles between Delhi and Gurgaon.
2. The children ran across the bridge.
3. Towards evening, you can hear the frogs croak.
4. I dug the flowerbeds with a spade.
5. The mountaineer reached the peak with great difficulty.
Explanation:
Prepositions are the words that tell us or gives information about the location, place, time, or the relation of the noun or pronoun with the other words in the sentence. In short, they tell us where, when, or how something happens.
The prepositions in the given sentences are underlined as follows-
1. The bus shuttles between Delhi and Gurgaon.
2. The children ran across the bridge.
3. Towards evening, you can hear the frogs croak.
4. I dug the flowerbeds with a spade.
5. The mountaineer reached the peak with great difficulty.
Solve these simultaneous equations:
3. 5x – 3y = 15 4x 3y = 6
2x + 5y = 26 4x + 3y = 24
3x + 3y = 39 2x - 3y = - 2
Answer:
1) We have the system:
5*x - 3*y = 15
4*x + 3*y = 6
To solve this, we first need to isolate one of the variables in one of the equations, let's isolate x in the first equation:
x = 15/5 + (3/5)*y = 3 + (3/5)*y
Now we can replace this in the other equation to get:
4*( 3 + (3/5)*y) + 3*y = 6
and solve this for y.
12 + (12/5)*y + 3*y = 6
(12/5 + 3)*y = 6 - 12 = -6
(12/5 + 15/5)*y = -6
(27/5)*y = -6
y = -6*(5/27) = 1.11
Now we can replace this in the equation:
x = 3 + (3/5)*y
To get the value of x.
x = 3 + (3/5)*1.11 = 3.67
Then the solution of this system is the point (3.67, 1.11)
2) Now we have the system:
2*x + 5*y = 26
4*x + 3*y = 24
The solution method is the same as before:
x = 26/2 - (5/2)*y = 13 - (5/2)*y
Now we replace this in the other equation:
4*( 13 - (5/2)*y) + 3*y = 24
52 - 10*y + 3*y = 24
52 - 7*y = 24
52 - 24 = 7*y
28 = 7*y
28/7 = y
4 = y
now we replace this in the equatio:
x = 13 - (5/2)*y
x = 13 - (5/2)*4 = 13 - 10 = 3
The solution of this sytem is (3, 4)
3) Now we have the system:
3*x + 3*y = 39
2*x - 3*y = -2
first we isolate x in the first equation:
x = 39/3 - 3*y/3 = 13 - y
Now we can replace this in the other equation:
2*(13 - y) - 3*y = -2
26 - 2*y - 3*y = -2
26 - 5*y = -2
26 + 2 = 5*y
28 = 5*y
28/5 = y = 5.6
Now we can replace this in the equation:
x = 13 - y
To get the x-value
x = 13 - 5.6 = 7.4
Then the solution for this system is (7.4, 5.6)

Manny is deciding between two packages of yogurt. YoFruit costs $4.48 for 16 ounces. Yummy Yogurt costs $2.64 for 8 ounces. How much more does Yummy Yogurt cost per ounce?
Answer:
16 is double 8, so just double the price: 2.64 x 2= $5.28
then, subtract to find the dufference: 5.28 - 4.48= $.80
then, divide that by the oz:
.80/16= 5 cents per ounce
Answer:
0.05

Taxis usually charge a fee on top of the per-mile charge. In this case, the taxi charges $3 as a set fee and $0.80 per mile traveled. The function y=0.8x+3 is used to represent the total cost of a ride.
Answer:
$12.3
Step-by-step explanation:
Given data
We are given that the function for the charge is expressed as
y=0.8x+3
Where y is the total cost for a ride
X is the distance of the ride
Say x= 12 miles
Hence the total cost of the ride is
Y= 0.8*12+3
Y= 9.6+3
Y= $12.3
Hence a 12 miles Distance will cost $12.3

There are 60 children in a club. In the club, the ratio of the number of girls to the number of boys is 3:1 3/5 of the girls play a musical instrument. 4/5 of the boys play a musical instrument. What fraction of the 60 children play a musical instrument?
Answer:
3/20
Step-by-step explanation:
There are 60 children in a club. In the club, the ratio of the number of girls to the number of boys is 3:1
Step 1
We find the number of girls and boys
The ratio is given as:
Girls : Boys
3:1
The sum of Proportion = 3 + 1 = 4
The number of girls
= 3/4 × 60 children
= 45 girls
The Number of boys
= 1/4 × 60 children
= 15 boys
Step 2
From the question, we are told:
3/5 of the girls play a musical instrument.
The number of girls that play Instruments is calculated as:
3/5 × Number of girls
= 3/5 × 45 girls
= 27 girls
4/5 of the boys play a musical
instrument.
The number of boys that play Instruments is calculated as:
4/5 × Number of boys
= 4/5 × 15 boys
= 12 boys
Step 3
The fraction of the 60 children that play a musical instrument is calculated as:
Sum of boys and girls that play a musical instrument/ 60 children
= 27 girls + 12 boys/60
= 39/60
= 3/20
The fraction of the 60 children that play a musical instrument is 3/20
sam and cliff are both saving money. sam starts with 20$ and save 10$ per week. cliff starts with 50 and saves 7$ per week. when will they have the same amount of money?
Answer:
i think that they will get the same amount after a week's pay
Answer:
10 weeks
Step-by-step explanation:
You start by looking for the number that would help make these equal. it would have to be a number that ended with a 5 or 0. that would be 10. 10x7=70. 70+50=120
120
then 10x10=100+20
120
they will be the same at

Plz help solve 7 and 8
Answer:
7) 16 sq units
8) L = 22 cm
Step-by-step explanation:
7) A = 1/2h·(sum of bases)
= 1/2(4)(5+3)
= 2(8) or 16 sq units
8) A (trapezoid) = 1/2(7)(10+12)
= 1/2(22)(7)
= 11(7) or 77 sq cm
To find 'l' in triangle:
A = 1/2·L·7
77 = 7L /2
7L = 154
L = 22 cm

Martha biked 55 miles per day and Enrico biked 145 miles every 3 days. After 6 days, which statement correctly compares the number of miles they each biked
Answer:
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.
Step-by-step explanation:
i. Martha bikes 55 miles per day.
So that after 6 days, Martha would have covered;
55 miles x 6 = 330 miles
After 6 days, Martha would have biked 330 miles.
ii. Enrico bikes 145 miles every 3 days.
Then after 6 days, Enrico would have covered;
[tex]\frac{6 days}{3 days}[/tex] x 145 miles
= 2 x 145 miles
= 290 miles
After 6 days, Enrico would have biked 290 miles.
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.
2.4x-6=0 domain and range
Answer:
if you help me, i help you
Answer:
x = 2.5
Step-by-step explanation:
2.4x - 6 = 0
2.4x - 6 + 6 = 0 + 6
2.4x = 0 + 6
2.4x = 6
2.4x ÷ 2.4 = 6 ÷ 2.4
x = 6 ÷ 2.4
x = 2.5
