HELP ASAP.!!!!!!! Jahlil is saving money at a constant rate to buy a new TV. After saving for $3$ months, Jahlil has $\$330$ . After saving for $5$ months, Jahlil has $\$510$ . Construct a function that models the relationship between the amount of money Jahlil has saved and the number of months he has saved for. Show or explain how you constructed the function. Respond in the space provided.
Answers
Answer:
y=90x+60
Step-by-step explanation:
x=months
y=dollars
Find dollars/month by finding the slope.
(3, 330), (5, 510)
-> (510-330)/(5-3) -> 90
Since its a constant rate, the function will be in the form, y=mx+b, and since we found the slope we can plug m=90.
y=90x+b
To find be, we simply substitute one of the points.
330=90(3)+b
b=60
Thus, plugging it in,
y=90x+60
Consider circle O below. The length of arc BA is 8.4 cm and the length of the radius is 8 cm. The measure of angle AOC is 45°. Circle O is shown. Line segments B O, A O and C O are radii with length 8 centimeters. The length of arc B A is 8.4 centimeters. Angle A O C is 45 degrees. Rounded to the nearest whole degree, what is the measure of angle BOA? ° Rounded to the nearest tenth of a centimeter, what is the length of arc BAC? cm
Answers
Answer:
i) 60°
ii) 14.7 cm
Step-by-step explanation:
length of Arc BA = 8.4 cm
length of radius = 8 cm
angle AOC = 45°
BO = AO = CO = 8 cm
i) What is the measure of Angle BOA
= length of Arc BA / Radius
= 8.4 / 8 = 1.05 radians = 60.16° ≈ 60°
ii) what is the length of arc BAC
= radius * angle BAC * [tex]\pi /180[/tex]
angle BAC = angle AOC + angle BOA
= 45° + 60° = 105°
hence length of arc BAC
= 8 * 105 * [tex]\pi /180[/tex]
≈ 14.7 cm
Answer:
Rounded to the nearest whole degree, what is the measure of angle BOA?

Writing You want to buy a pet iguana that costs $50. You already have $16 and you plan to save $7
per week. If w represents the number of weeks until you have enough money to buy the iguana, what
equation could you use to find the value of w? Use pencil and paper. Explain how you could set up an
equation to find the amount of money you should save each week if you want to buy the iguana in
three weeks.
Answers
Answer:
50 = 16 + 7w
amount to save each week for 3 weeks = $11.33
Step-by-step explanation:
Cost of pet iguana = $50
Amount you have = $16
Savings per week = $7
Number of weeks = w
Equation:
50 = 16 + 7w
To find w
50 - 16 = 7w
34 = 7w
w = 34/7
w = 4.86
Approximately w = 5 weeks to the nearest whole week
if you want to buy the iguana in
three weeks
Let x = amount to save each week for 3 weeks
50 = 16 + 3x
50 - 16 = 3x
34 = 3x
x = 34/3
x = 11.33
amount to save each week for 3 weeks = $11.33
If f(x)=2x−3 and g(x)=4x+5, what is (f⋅g)(x)?

B)(f⋅g)(x)=6x+2
C)(f⋅g)(x)=8x2+22x−15
D)(f⋅g)(x)=8x2−2x−15
Answers
9514 1404 393
Answer:
D) (f⋅g)(x)=8x2−2x−15
Step-by-step explanation:
(f·g)(x) = f(x)·g(x) = (2x -3)(4x +5) = 2x(4x +5) -3(4x +5)
= 8x² +10x -12x -15
(f·g)(x) = 8x² -2x -15

the angle of a quadrilateral are in the ratio 1 : 2 :3 :4 if the sum of the angles of a quadrilateral is 360 degree find the measure of each angle
Answers
Answer:
Step-by-step explanation:
Let the angles of quadrilateral be
x, 2x, 3x , 4x
sum of all angles of quadrilateral = 360°
x + 2x + 3x + 4x = 360°
10x = 360°
x = 360/10 = 36°
Ans. the four angles are :-
x = 36°
2x = 2 × 36 = 72°
3x = 3 × 36 = 108°
4x = 4 × 36 = 144°
Answer:
Step-by-step explanation:
Let the angles of quadrilateral be
x, 2x, 3x , 4x

10x = 360°
x = 360/10 = 36°
Ans. the four angles are :-
x = 36°
2x = 2 × 36 = 72°
3x = 3 × 36 = 108°

Item 9 Write an equation that you can use to find the value of x. Perimeter of triangle: 16 in.
Answers
Answer:
16 = 3x
Step-by-step explanation
Find the diagram attached.
Perimeter = sum of all its sides
Sum of all its sides= x+x+x
Sum of all its sides = 3x
Given perimeter = 16in
Equating both;
3x = 16
x = 16/3
x = 5.33in
Hence the value of x is 5.33 and the required equation is 16 =3x

y ≤ 2x + 1
To determine if (4, 10) is a solution to the inequality, we want to plug in the given values.
10 ≤ 2(4) + 1
[multiply] 10 ≤ 8 + 1
[add] 10 ≤ 9
Determine if this statement is true.
10 is greater than 9; therefore (4, 10) is not a solution to this inequality.
Hope this helps!

No

If you plug in 10 for y and 4 for x, you will get 10 ≤ 9 which is false.

$400 interest is earned on a principal of $2,000 at a simple interest rate of 5% interest per year. For how many years was the principal invested?
Answers
Answer:
4 years
Step-by-step explanation:
Given data
Simple interest= $400
Principal= $2000
Rate= 5%
The simple interest formula is given as
SI=PRT/100
substitute and solve for T
400=2000*5*T/100
cross multiply
400*100= 10000*T
40000=10000T
T= 40000/10000
T= 4 years
Hence the time taken is 4 years

Maggie uses 6.9 pints of white paint and blue paint to paint her bedroom walls. 3 5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answers
Answer:
2.76 pints
Step-by-step explanation:
Given that:
Tottal amount of paint used = 6.9 pints
The faction of white paint used = 3/5
Hence, Amount of white Paint used :
3/5 * 6.9 = (3 * 6.9) / 5 = 4.14 pints of white paint.
Pints of blue paints used :
Total pints - pints of white used
6.9 - 4.14 = 2.76 pints of blue paint
