NEED HELP ASAP

Answer:

Y=0.35x+18.99

Step-by-step explanation:

Y = total cost

X = number of letters

Answer:

y= 0.35x+18.99

m= 0.35

18.99= 0.35(0)+b

18.99= 0+b

18.99=b

Answer:

1. $33.00

2. $48.00

3. $3.00

4. $36.40

Step-by-step explanation:

44.00 - 25% = 33 —> $33.00

80.00 - 40% = 48 —> $48.00

9.99 - 70% = 2.997 —> (round the 7 up because it's above 5) $3.00

52.00 - 30% = 36.4 —> $36.40

Answer:

Step-by-step explanation:

Answer:

42°

Step-by-step explanation:

[tex] \triangle ABC\cong\triangle TUV.. (given) [/tex]

[tex] \therefore \angle B\cong\angle U[/tex]

[tex] \therefore m\angle B=m\angle U[/tex]

Therefore,

(2y + 2)° = (3y - 18)°

2y + 2 = 3y - 18

2y - 3y = - 2 - 18

-y = - 20

y = 20

[tex] m\angle U=(3y-18)\degree [/tex]

[tex] m\angle U=(3\times 20-18)\degree [/tex]

[tex] m\angle U=(60-18)\degree [/tex]

[tex] m\angle U=42\degree [/tex]

Step-by-step explanation:

2,136 divided by 6

Answer:

105 for all of them

Step-by-step explanation:

1) take 180-75, because of opposite angles.

105

2)again, 105 because we know the opposite angle is 75

3)105

again, opposite angles.

Answer:

True statements are:

(i) The lane 2 turtle is faster than the lane 1 turtle.

(iv) The lane 1 turtle has a head start.

Step-by-step explanation:

Now we proceed to check the value of truth for each choice:

(i) The lane 2 turtle is faster than the lane 1 turtle.

Speed of the turtle is the slope of the linear function, the greater the slope, the faster the turtle. Hence, the lane 2 turtle is faster than the lane 1 turtle. (Answer: TRUE)

(ii) At 3 seconds, the turtle in Lane 2 is 12 feet from start.

Let the position of the turtle in Lane 2 be represented by [tex]d = 3\cdot t[/tex]. For [tex]t = 3\,s[/tex], then [tex]d = 3\cdot (3) = 9[/tex]. Hence, the turtle in Lane 2 is just 9 feet from the start. (Answer: FALSE)

(iii) At 12 seconds, the turtle in Lane 1 is 6 feet from the start.

Let the position of the turtle in Lane 1 be represented by [tex]d = 6 + t[/tex]. For [tex]t = 12\,s[/tex], then [tex]d = 6+12 = 18[/tex]. Hence, the turtle is 12 feet from the start. (Answer: FALSE)

(iv) The lane 1 turtle has a head start.

According to graph, Lane 1 turtle starts at a position of 6 feet, whereas Lane 2 turtle start at a position of 0 feet. Hence, Lane 1 turtle has a head start. (Answer: TRUE)

Answer:

£15000

Step-by-step explanation:

Lucy, Mary and Nora's father leaves them an inheritance in the

ratio 5: 3:2. Mary gets £4500, How much was there in total?

Giving the ratio of inheritance 5:3:2

5+3+2 = 10

Mary's ratio = 3

Marys share = £4500

Total share x can be gotten as thus

3/10 × x = 4500

3x/10 = 4500

3x = 45000

x = 45000/3

x = 15000

Hence £15000 was there in total

Answer:

D. (2, -1)

Step-by-step explanation:

I took the test and got it right.

Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1). So, the coordinates of point S will be (2, -1).

Let the point be having coordinates (x,y).

If the point is in first quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

If the point is in the second quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Triangle QRS is rotated 180° about the origin.

On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1).

So, the coordinates of point S will be (2, -1).

Hi there!

cost=64.0125

1.Multiply percent with 0.01:

[tex]25[/tex]·[tex]0.01=0.25[/tex]

2.Multiply the cost and term:

[tex]85.35[/tex]·[tex]0.25= 21.3375[/tex]

3.Subtract first term with the decrease of cost:

[tex]85.35-21.3375= 64.0125[/tex]

Therefore, the sale price of the girl is now 64.0125$
