Deposits into a bank account are represented by numbers. Withdrawals from the account are represented by negative numbers. Which amount represents a withdrawal of less than $ 200?

Answer:2(xy-7)= -20

Step-by-step explanation:

Plug in -1 for x and 3 for 3, as the question says that x and y represent those values.

2(xy-7) = ?

2((-1)(3) - 7) = ?

2(-3-7)=?

2(-10)

-20

2(xy - 7) = -20

The expresssion 2(xy - 7) = -20 , when x = -1 & y = 3

In mathematics, if two or more numbers or variables present with one or more mathematical operations, then the statement is called expression.

Example : 4x-3y+4, where x,y are variables, 3 & 4 are numbers and they are operated with addition and subtraction, so this is an expression.

Here, in the problem, x = -1 & y = 3

The given expression is 2(xy - 7) .....(1)

Now, we have to put the values of x & y in (1),

So, 2(xy - 7)

  = 2{(-1)(3)-7}

  = 2{-3-7}

  = 2×(-10)

  = -20

So, the value of the expression is -20

Answer:

C

Step-by-step explanation:

A quadratic function can be defined as a function where the highest degree or exponent is 2. Since option B has a zero in front of the x squared, it is not a quadratic function because 0 times anything is zero. Therefore, the only other option with an exponent of 2 is C.

Answer:

⅞ pound

Step-by-step explanation:

You received 1/4 pound of candy from your grandmother.

You received 1/2 pound of candy from your sister.

You received 1/8 pound of candy from your best friend.

The total amount of candy you received is given as the sum of all the candy that he received from your grandmother sister and best friend.

The total amount of candy is therefore:

¼ + ½ + ⅛ = ⅞ pound

You received ⅞ pound of candy in total.

c=36+g

c:g:s=5:2:1

The ratio gives us two equations so that's three equations in three unknowns.  Actually we're after the total t; let's put that in to solve for directly.

c:g:s:t = 5 : 2 : 1 : 5+2+1

We turn the ratio to fraction equations.  s has the one; let's write everything in terms of s.

c/s = 5/1,  g/s = 2/1, t/s = 8/1

Clearing the fractions,

c = 5s, g = 2s, t = 8s

Our other equation is

c = 36 + g

Substituting in for c and g,

5s = 36 + 2s

Solving,

3s = 36

s = 12

That's right; let's just get the total t.

t = 8s = 72

Answer:

18.75 cubic yards

Step-by-step explanation:

Multiply the length width and height by each other.

50 x 1.5 x 0.25 = 18.75

Answer:

18.75 yards³

Step-by-step explanation:

To solve this, we can solve for the volume of the rectangular prism by using the formula: [tex]V= l*w*h[/tex]

We can plug in the values, giving us:

V= 50×1.5×0.25= 18.75 yards³

Answer: 35 chocolates were bought and 52 gums were bought.

Step-by-step explanation:

c + g = 87    where c is the number of chocolate and g is the number og gums

1.50c + 0.50g = 78.50    solve both equations by elimination.

-1.50c - 1.50g =  -130.5

1.50   + 0.50g = 78.50

           -1g =  -52

             g= 52

1.50c + 0.50(52) = 78.50

 1.50c + 26 = 78.50

             -26     -26

1.50c = 52.5

c = 35

Answer:

[tex] 1400 = x(x+10)= x^2 +10x[/tex]

We can rewrite this expression like this:

[tex] x^2 +10 x -1400 =0[/tex]

And we can use the quadratic formula given by:

[tex] x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]

Where [tex] a =1 , b=10 , c= -1400[/tex]

And replacing we got:

[tex] x = \frac{-10 \pm \sqrt{10^2 -4(10)(-1400)}}{2*1}[/tex]

And solving we got:

[tex] x_1 =32.75 , x_2 = -42.75[/tex]

And since the value can't be negative the answer would be x = 32.75 and the value of y = 32.75+10 =42.75

Step-by-step explanation:

For this case we know that we have a rectangular playground and the area can be founded with this formula:

[tex] A = xy[/tex]

Where x represent the width and y the length. From the problem we know that A =1400 m^2 and the heigth is 10m longer than the wide so we can write this condition as:

[tex] y = 10 +x [/tex]

And replacing this formula into the area we got:

[tex] 1400 = x(x+10)= x^2 +10x[/tex]

We can rewrite this expression like this:

[tex] x^2 +10 x -1400 =0[/tex]

And we can use the quadratic formula given by:

[tex] x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]

Where [tex] a =1 , b=10 , c= -1400[/tex]

And replacing we got:

[tex] x = \frac{-10 \pm \sqrt{10^2 -4(10)(-1400)}}{2*1}[/tex]

And solving we got:

[tex] x_1 =32.75 , x_2 = -42.75[/tex]

And since the value can't be negative the answer would be x = 32.75 and the value of y = 32.75+10 =42.75

Answer:

Step-by-step explanation:

Given Data:

Area = 1400m²

L = 4+w

W= w

Area = L * W

1400 = ( 4+W) W ²

1400 = 4w + w ²

w ² + 4w - 1400 = 0

- b ± √ b ² - 4ac / 2a

Where;

a = 1

b = 4

c = -1400

- 4 ± √4² - 4(1)(-1400) / 2(1)

= - 4 ± 74.94 /2

= - 4 + 74.94 / 2 or - 4 - 74.94 / 2

= 35.47 or - 39.47

Answer: 29.0

Step-by-step explanation:

The volume of a pyramid is equal to l*w*h/ 3  and we know that the length times the width is the same as the base.

so we will multiply 8.7 * 10= 87 /3=  29

Volume = 87 m³

You need to multiply the area and the height to find the volume. If you have the length, width, and height, then you need to multiply and 3 and divide it by 3. Hope I helped :)

Answer:

Option 6

Step-by-step explanation:

To find the volume of a cone you use the formula 1/3*pi*r^2*h which would be pi*9^2*7. Then the volume of a cylinder is pi*9^2*50, so option 6 is right I believe.

Answer: 22 is 78% of 28

Step-by-step explanation:

22÷28×100=78

78 is the percentage

Answer:

28. 21 or 28.2 or 28

Step-by-step explanation:

Since 22 is equal to 78% percent, then x is equal to 100%

78% = 22

100% = x

Cross múltiply

100(22) = 78x

2200 = 78x

÷ 78. ÷78

28.205 = x

Depending on what your rounding off to, nearest tenth, hundreths, or whole number

tenth = 28.2

whole number= 28

hundreth= 28. 21

Answer:

He will earn an interest of $448 in 4 years

Step-by-step explanation:

In this question, we are interested in calculating the interest earned on an investment for a period of 4 years.

To calculate this interest, we shall be using the formula for simple interest but with slight difference in terms definition

Mathematically;

I = PRT/100

Where ;

P is the amount invested which is $1,750 according to the question

R is the interest rate which is 6.4%

T is the time which is equal to 4 years

Plugging these figures, we have

I = (1,750 * 6.4 * 4)/100 = 44,800/100 = $448

Answer:

The probability that it is a cookie is   [tex]\frac{2}{15}[/tex]

Step-by-step explanation:

To find the probability  that it is a cookie if he chooses one at random;

probability = required outcome / all possible outcome

The all possible outcome will be gotten by adding up all the snacks. that is;

required outcome = 5 + 8 + 2 = 15

The required outcome is the snack he chooses, that is; required outcome = 2

Probability (of choosing a cookie) =required outcome / all possible outcome

                                                         =[tex]\frac{2}{15}[/tex]

Therefore, the probability that it is a cookie is   [tex]\frac{2}{15}[/tex]

Answer:

3/12 or 1/4

Step-by-step explanation:

To find what is between, we have to use the formula:

x + y= z

z/2 = midpoint!

So, we can do that with this number.

1/6 + 2/6 = 3/6. We could simplify it, but let’s keep it at 3/6

3/6 divided by 2 = 3/6 · 1/2 = 3/12

So, the midpoint would be 3/12.
