Answer:

a= -40

Step-by-step explanation:

Answer:

a = - 40

Step-by-step explanation:

a+40=0

First way:

Transpose 40 to the other side (to isolate a) - when transposing signs change ( from positive to negative)

Second way:

Subtract both side what 40 (to cancel 40 and isolate a)

* you have to always isolate variables

Answer: The coordinates of point S is (14,-10).

Step-by-step explanation:

Midpoint of line joining [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by :-

[tex](x,y)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

Given, The coordinates of point T are (0,2). The midpoint of ST is (7, -4).

Let (a,b) be the coordinates of point S.

Then,

[tex](7,-4)=(\dfrac{0+a}{2},\dfrac{2+b}{2})\\\\\Rightarrow\ 7=\dfrac{a}{2},\ \ \ -4=\dfrac{2+b}{2}\\\\\Rightarrow\ a=7\times 2= 14, \ \ 2+b= 2\times-4 =-8\\\\\Rightarrow\ a=14,\ \ \ 2+b=-8\\\\\Rightarrow\ a=14, \ b= -8-2=6--10\\\\\Rightarrow\ a=14,\ b=-10[/tex]

Hence, the coordinates of point S is (14,-10).

Answer:

MN = 4

Step-by-step explanation:

Given that L, M, N are collinear,

LN = 9,

MN = 4x

LM = 5x

Required:

Length of MN

SOLUTION:

To calculate the numerical length of MN, we need to find the value of x.

To find the value of x, generate an equation to solve for x as follows:

[tex] LM + MN = LN [/tex] (segment addition postulate)

[tex] 5x + 4x = 9 [/tex] (substitution)

Solve for x

[tex] 9x = 9 [/tex]

Divide both sides by 9

[tex] \frac{9x}{9} = \frac{9}{9} [/tex]

[tex] x = 1 [/tex]

MN = 4x

plug in the value of x

MN = 4(1) = 4

Answer:

14 hours and 26 minutes

Step-by-step explanation:

The correct statements will be a line has only one dimension and two endpoints.

A line is simply an object in geometry that is characterized under zero width object that extends on both sides.

So, from here we can see that a line has two endpoints.

We also know that the line has only one dimension.

Answer:

LEON (2.1), JASON (2.4), ASHLEY (2.5), MIKA (2.6)

Step-by-step explanation:

To order their perimeter from the least to the greatest, express all perimeters in decimals:

LEON = √17 - 2 = 4.1 - 2 = 2.1

MIKA = 1 + π/2 = 1 + 22/7*½ = 1 + 22/14 = 1 + 1.6 = 2.6

JASON = 12/5 = 2⅖ = 2.4

ASHLEY = 2.5

From least to greatest, we have: LEON (2.1), JASON (2.4), ASHLEY (2.5), MIKA (2.6)

Answer:

twenty teeth

Step-by-step explanation:

32:8=4

4•5=20

Answer:

Pat has lost 12 teeth.

I got a calculator and divided 32 by 8, then timed that answer (4) by 3.

32 ÷ 8 = 4

4 x 3 = 12

If the question had asked how many teeth Pat has, the answer would be 20, but that isn't correct for this question. It asks how many teeth she has lost, and that would be 12.

Answer:

11. 9hrs

12. 5hrs 35min

13. 3hrs 48 min

Step-by-step explanation:

Makes it a bit easier if you convert to 24 hr time.

11. 10 - 19 is 9hrs

12. 545-1120 is 11-5 20-45 -> 6hrs -25min -> 5hrs 35min

13. 1800 - 2148 is 21-18 48-00 -> 3hrs 48 min

Answer:

11. 9h

12. 5h 35 min

13. 3h 48min

Step-by-step explanation:

11.

here,

time elapsed = ∆t = final time - initial time

= 7 pm - 10 am

= (12+7) h - 10 h {turn pm into am by adding 12 and converting both into hour and min}

= 9 h

12.

similarly,

time elapsed = ∆t = final time - initial time

= 11 h 20 min - 5 h 45 min

= 5 h 35 min

13.

similarly,

time elapsed = ∆t = final time - initial time

= 9 h 48min - 6 h

= 3h 58min

Answer:

the next terms would be 72 and 60

The next two term are :72 and 60

To get the next two term we are going to substract 1/2, 1/3, 1/4, 1/5, 1/6 from each sequence.

Sequence:360, 180,120,90

360-1/2×360

=360-180

=180

180-1/3×180

=180-60

=120

120-1/4×120

=120-30

=90

90-1/5×90

=90-18

=72

72-1/6×72

=72-12

=60

Inconclusion The next two term are :72 and 60

Step-by-step explanation:

Answer:

7  1/24

Step-by-step explanation:

1 2/3+5 3/8=?

first you need to find the least common multiple between 2/3 and 3/8.

the lcm would be 24, so 24 would be your new denominator for both fractions, but the numerators will change to how much you just multiplied each denominator by to get 24. 8x3 is 24, so you would multiply 3x3 to get the new numerator: 9. 3x8 is 24, so you multiply 2x8 to get the new numerator for that fraction:16.

so your new fractions are 1 16/24 + 5 9/24

now you add 16+9=25 (25/24, which becomes 1  1/24), so then you have another whole number: +1, and you add it to 5+1, so no it's 5+1+1=7

so the answer would be 7 1/24

Answer:

  $1445

Step-by-step explanation:

The side length of the room is the cube root of the volume of the cube:

  s = ∛4913 = 17 . . . . feet

The area of the floor is the square of this side length:

  A = (17 ft)² = 289 ft²

The cost of the floor is $5 for each square foot:

  cost = ($5/ft²)(289 ft²) = $1445

The hardwood floor will cost $1445.
