Step-by-step explanation:

We can split the figure into a 6 by 15 rectangle and a parallelogram (8 base, 7 height).

Answer:

3/16

Step-by-step explanation:

so since there isnt a half of 3/8 we would multiply the number x2 so the number is 6/16 and half of that is 3/16 becuase 6 can be split in half

Answer:

7. -

a. 3.5 or 7/2 hours

b. 24.5

c. After 7 hours (and at the beginning when t=0)

8. -

a. 4 seconds

b. 1 second

c. 54 meters

Step-by-step explanation:

7. M(t)=-2t^2+14t

M’(t)=-4t+14

a)

-4t+14=0

4t=14

2t=7

t=7/2

b) M(7/2)=24.5

c)

M(t)=0

-2t^2+14t=0

t^2-7t=0

t(t-7)=0

t=0, 7

8.

a)

h(t)=0

-6t^2+12t+48=0

t^2-2t-8=0

(t-4)(t+2)=0

t=-2, 4

t=4

b)

h(t)=-6t^2+12t+48

h’(t)=-12t+12

h’(t)=0

-12t+12=0

12t=12

t=1

c) h(1)=54

Answer:

x=1.47

Step-by-step explanation:

15(x-1)+4(x+3)=2(x+9)+4

15x-15+4x+12=2x+18+4

19x-3=2x+22

17x=25

x=25/17

x=1.47

x=1.47

Answer:

A) x=9

Step-by-step explanation:

48-12=36.

36/4=9

More detailed explanation:

4x+12=48

    -12    -12

     4x = 36

     /4     /4

     x   =    9

The solution of the equation is, x = 9.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The equation is,

⇒ 4x + 12 = 48

Now, We can solve the equation for value of x as;

⇒ 4x + 12 = 48

Subtract 12 both side, we get;

⇒ 4x + 12 - 12 = 48 - 12

⇒ 4x = 36

Divide by 4;

⇒ 4x/4 = 36/4

⇒ x = 9

Answer:

for number 4 i think it is option 3

Answer:

It would be positive

Step-by-step explanation:

To do anything with fractions you need to find a common denominator, in this case lets say its 128. the 9 in the negative side would need to be multiplied by 8 like it's denominator making it 72. You would do the same to the other fraction giving you the fractions -72/128 and 144/128 from here you add to get 72/128 which is positive

Answer:

positive

Step-by-step explanation:

-9/16= -0.5625

9/8= 1.125

-9/16+9/8= -0.5625 + 1.125(in the addition of opposite signs u should figure out the largest num and should substract the other numa nd assign the sign of the biggest nym)

              =0.5625

  the reason

             + * + = +

              - * - = +                                              

              + * - = -

              +/+ =+

              - / - = -

              -/ + = -

              + / - = -

No, the first ten perfect cubes are 1, 8, 27, 64, 125, 216, 343, 512, 729 and 1000.

Answer:

Thank you I needed this today *smiles*

Step-by-step explanation:

Answer:

(1,3)

Step-by-step explanation:

starting at (0,0)

vertically scaled by 4 - go up four (0,4)

reflected on y axis - negative the four (0,-4)

translated 1 to the right and 7 up - go up 7 and to the right 1 (1,3)

hope this helps :)

Answer:

The values of x for which the model makes sense is [tex]x\ge 6\,ft[/tex].

Step-by-step explanation:

From statement we have the following expression for the volume of the rectangular room is:

[tex]V(x) = 2\cdot x^{3}-14\cdot x^{2}+12\cdot x[/tex] (1)

Where:

[tex]V[/tex] - Volume of the rectangular room, measured in cubic feet.

[tex]x[/tex] - Length of the room, measured in feet.

By Algebraic means we factorize the polynomial:

[tex]V(x) = x\cdot (2\cdot x^{2}-14\cdot x +12)[/tex]

[tex]V(x) = x\cdot (x-6)\cdot (x-1)[/tex]

Given that both volume and length must be positive variables, then the following conditions must be satisfied:

[tex]x \ge 0\,ft\,\land\,x\ge 6\,ft\,\land\,x\ge 1\,ft[/tex]

Then, the values of x for which the model makes sense is [tex]x\ge 6\,ft[/tex].

Answer:

[tex]\displaystyle -0.\overline{37}=-\frac{37}{99}[/tex]

Step-by-step explanation:

Convert a Repeating Decimal to a Fraction

We need to convert the following decimal to a fraction:

[tex]-0.\overline{37}[/tex]

Let's call x to the given number:

[tex]x=-0.\overline{37}[/tex]

The number has two repeating (periodic) decimals, thus we multiply by 100:

[tex]100x=-37.\overline{37}[/tex]

Note the decimals continue to repeat exactly like the original number.

Subtracting both expressións, the repeating decimals are simplified:

[tex]100x - x = -37[/tex]

Operating:

99x=-37

Dividing by 99:

[tex]\displaystyle x=-\frac{37}{99}[/tex]

The fraction cannot be simplified, thus:

[tex]\mathbf{\displaystyle -0.\overline{37}=-\frac{37}{99}}[/tex]

the x coordinate is 0 and the y coordinate is 4

she will have $2065 in her savings account after the 25th week.

Answer:

2,065

Step-by-step explanation:

First you need to figure out 65 times 25 because she puts $65 into her account every week so you need to multiply by 25 because you have to figure out how much money she will have on the 25th week so:

$65 * 25 = 1,625

then you need to add that to 440 because ahe still only has 440 in her account until now so, in conclusion, she has 2,065 because:

$65 * 25 = $1,625 + $440 = 2,065

I hope this helped! I am not very good at explaining.
