HELP TRUE OR FALSE 25 POINTS!!

Answer:

0.4

Step-by-step explanation:

The formula to calculate number of black marbles isnumber of favourable items by number of favourable items i.e for black marbles it will become

P(B)=number of black marbles divide by total number of marbles

P(B)=6/15

P(B)=0.4 OR 40%

Therefore the probability that Tommy will pick black marble is 0.4 or 40%

Answer:

  0.72 pounds

Step-by-step explanation:

Each of the 7 people gets 1/7 of the pounds of pie, so ...

Answer:

102

Step-by-step explanation:

Let x be the amount of money John spends.

x/2-5=46

x/2=51

x=102

Hey there!

2/7(x + 4) = -6

2/7(x) + 2/7(4) = -6

2/7x + 8/7 = -6

SUBTRACT 8/7 to BOTH SIDES

2/7x + 8/7 - 8/7 = -6 - 8/7

CANCEL out: 8/7 - 8/7 because it gives you 0

KEEP: -6 - 8/7 because it helps solve for the x-value

NEW EQUATION: 2/7x = -6 - 8/7

SIMPLIFY IT!

2/7x = -50/7

MULTIPLY 7/2 to BOTH SIDES

7/2 * 2/7x = 7/2 * (-50/7)

CANCEL out: 7/2 * 2/7 because it gives you 1

KEEP: 7/2 * (-50/7) because it helps solve for the x-value

NEW EQUATION: x = 7/2 * (-50/7)

SIMPLIFY IT!

x = -25

Therefore, your answer is: x = -25

Good luck on your assignment and enjoy your day!

Answer:

1: 11982.79

2: 12136.31

4: 12216.09

12: 12270.46

365: 12297.10

Step-by-step explanation:

The compound interest formula is A=P*(1+r/n)^nt

P=principal amount

r=rate

n=number of compounds per period

t=number of periods

In this situation, the principal amount is 5,000=P. The rate is 6%, so r=0.06. n is equal to the top number in the table. And this is 15 years, so t=15.

For 1, it would be A=5,000*(1+.06/1)^1*15, or A=5,000(1.06^15), or 11982.79.

For 2, it would be 5,000*(1+.06/2)^2*15, or 5,000*(1.03^30), or 12136.31.

And so forth. Good luck

The coordinates of the midpoint will be (4,5).

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line. Given that the midpoint of AB is M(-2,2) and the coordinates of A are (-8, -1).

The midpoint will be calculated by using the formula below:-

( -8 + x ) / 2 = -2

( -8 + x ) = -4

x = -4 + 8 = 4

( -1 + y ) / 2 = 2

( -1 + y ) = 4 = 1 + 4 = 5

Therefore, the coordinates of the midpoint will be (4,5).

Step-by-step explanation:

15.4 rounds down to 15

5.7 rounds up to 6

15 × 6 = 90

Step-by-step explanation:

6<7m+6m or 3m-6m<5+7

6<13m or -3m<13

Answer:

x=10/c

Step-by-step explanation:

3(cx-7)=9

(cx-7)=3

cx=10  

x=10/c

Answer:

x=10/c

Step-by-step explanation:

3(cx-7)=9

(cx-7)=3

cx=10  

x=10/c

h = 15√3/4

= 6.4875

≈ 6.5 cm

h = 3x

c₁ = 5 cm

c₂ = x

h² = c₁² + c₂²

(3x)² = 5² + x²

9x² = 25 + x²

8x² = 25

x² = 25/8

x = √25/8

x = 5/2√2

x = 5√2/4

h = 3x

= 3×5√2/4

= 15√2/4 cm

ok so 68 customers everything morning times 7 days per week is 476 customer.

now we know that 476 x .67 = $318.92

she make 8.50 per week plus $318.92 from customers

now we have this equation of

500 = 8.5x + 318.92

find x you will know how many weeks she needs.

8.5x = 500 - 318.92

8.5x = 181.08

x = 181.08/ 8.5

x ~~ 21.3 weeks

Answer:

1o weeks

Step-by-step explanation:

As I understand it she get's paid 8.50 per week

8.50x

and 0.67 per customer per week

0.67(68)x since there are 68 customers

it has to be at least 500

[tex]8.5x+0.67(68)x\geq 500\\\\8.5x+45.56x\geq 500\\\\56.06x\geq500\\\\x\geq\frac{500}{56.06} \\\\x\geq 9.24...\\\\x=10[/tex]

Answer:

True, assuming you mean on any graph.

Step-by-step explanation:

The graph starts at a value in between 1 and 2 while the expression starts at a value of 6, therefore, the expression has a higher initial value.

Answer:62

Step-by-step explanation:

62^2

[tex]\Huge{\boxed{\sf{\red{22.98m}}}}[/tex]

According to the question,

Slant height, l = [tex]\displaystyle{\sf{ \sqrt{{r}^2 + {h}^2} = \sqrt{{3.5}^2 + {8.5}^2}}}[/tex]

[tex]\implies[/tex] [tex]\displaystyle{\sf{ = 9.192m}}[/tex]

curved surface area = [tex]\displaystyle{\sf{ \pi rl}}[/tex]

[tex]\implies[/tex] [tex]\displaystyle{\sf{ \frac{22}{7} \times 3.5 \times 9.192{m}^2}}[/tex]

[tex]\implies[/tex] [tex]\displaystyle{\sf{ 101.112}}[/tex]

i.e., Area of the cloth is 101.11m²

Now, length of the cloth required = [tex]\displaystyle{\sf{ \frac{area}{width}}}[/tex]

[tex]\implies[/tex] [tex]\displaystyle{\sf{ \frac{101.11}{4.4}}}[/tex]

[tex]\implies[/tex] [tex]\large{\boxed{\sf{\red{22.98m}}}}[/tex]

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

[tex]2x-3y+5-\left(x-3y\right)=11-2x[/tex]

Remove brackets and flip the sign in the brackets:

[tex]2x-3y+5-x+3y=11-2x[/tex]

Group the similar terms together:

[tex]-3y+3y+2x-x+5=11-2x[/tex]

Add/subtract the terms:

[tex]x+5=11-2x[/tex]

Subtract 5 from both sides:

[tex]x+5-5=11-2x-5[/tex]

[tex]x=-2x+6[/tex]

Add 2x to both sides:

[tex]x+2x=-2x+6+2x[/tex]

[tex]3x=6[/tex]

Divide both sides by 3:

[tex]\frac{3x}{3}=\frac{6}{3}[/tex]

[tex]x=2[/tex]

Answer:

7 Centimeters (CM)

Step-by-step explanation:

You want to divide the perimeter by 4 to find the individual lengths. (28/4) Therefore each side of the square is 7cm long.

You are increasing all sides by a scale factor of 3.

This gives each side a length of 21cm

Hope this helped!

Answer:

7ft

Step-by-step explanation:

A square has 4 congruent sides so that means all sides are the same.

28 ÷ 4 = 7
