There are 32 ounces of water in a glass. Someone drinks 55% of the water. How many ounces of water are left? Answer without units.

Answers

Answer:

14.4

Step-by-step explanation:

If someone drinks 55%, that means 45% is left over. You multiply 32 x 45 to find out what is left.

Answer:

14.4

Step-by-step explanation:

lets start with the 55% it means 55/100

so we need to calculate the the ounces that the person drank which is:

32*15/100=17.6ounces

now to get the ounces left we should subtract the ounces that was drunk from the 32 ounces which is:

32-17.6=14.4

Step-by-step explanation:

Dog=12

Fish=6

12+6=18

The answer is C. 12 people have a dog as their favorite pet and then 6 people have a fish as their favorite pet. So you take 12+6=18 which is C. Hope this helps!

a. Write a formula for the area A
of a triangle.
b. Solve the formula for b.
c. Use the new formula to find the
base of the triangle.
A = 36 mm2
h = 6 mm
b

Answers

Answer:

A = 1/2 b * h

b = 2A / h

b = 12

Step-by-step explanation:

Remark

The formula starts out as

A = 1/2 * b * h

You want to rearrange it to show b by itself.

Formula

Multiply by 2

2A = b * h

Divide by h

2A/h = b

Part C

b = 2A / h

A = 36 mm^2

h = 6 mm

b = 2*36 / 6

b = 72 / 6

b = 12 mm

A circle is shown. Secant X Z and tangent W Z intersect at point Z outside of the circle. Secant X Z goes through the center of the circle and intersects the circle at point Y. The length of W Z is k + 4, the length of Z Y is k, and the length of X Y is 12.

What is the length of line segment XZ?

Answers

Given:

Consider the below figure attached with this ques.

To find:

The length of the line segment XZ.

Solution:

According to the tangent-secant theorem, the square of tangent is equal to the product of secant and external segment of secant.

Using tangent-secant theorem, we get

[tex]WZ^2=ZX\times ZY[/tex]

[tex](k+4)^2=(k+12)k[/tex]

[tex]k^2+8k+16=k^2+12k[/tex]

[tex]8k+16=12k[/tex]

Subtract both sides by 8k.

[tex]16=12k-8k[/tex]

[tex]16=4k[/tex]

Divide both sides by 4.

[tex]4=k[/tex]

Now,

[tex]XZ=12+k[/tex]

[tex]XZ=12+4[/tex]

[tex]XZ=16[/tex]

Therefore, the measure of XZ is 16 units.

Which equation represents a nonlinear function? y=−85x+19.4 y = − − 8 5 x + 19.4 y=−12x2−7 y = − − 1 2 x 2 − − 7 y=x4+x y = x 4 + x y=32−4

Answers

Answer:

The answer is below.

Step-by-step explanation:

The options are not clear. I would solve a similar question.

A linear function is a function in the form:

y = mx + b; where y and x are variables, m is the slope and b is the y intercept.

From the options:

a) x(y - 5) = 2

xy - 5x = 2. Since the equation is not in the form of y = mx + b, hence it is not a linear function. It is a nonlinear function.

b) y - 2(x + 9) = 0

y - 2x - 18 = 0

y = 2x + 18. The equation is in the form of y = mx + b, hence it is a linear function.

c) 3y + 6(2 - x) = 5

3y + 12 - 6x = 5

3y = 6x - 7. The equation is in the form of y = mx + b, hence it is a linear function.

d) 2(y + x) = 0

2y + 2x = 0

2y = -2x. The equation is in the form of y = mx + b, hence it is a linear function.

Step-by-step explanation:

Use the one point that is completely filled out, (6, 840). Divide 840 by 6 and you get 140 so that is the slope. 5x140= what the y intercept will be, 700. 420/140= what the x intercept will be, 3. Now you can see a pattern which helps check your work. They are all decreasing pretty much, not really ordered much but. And finally the last point 4x140=560. Hope that helps! :)

There are about half a million heart attacks deaths in the United States of America each year acording to womensheart.Org about how many heart attack deaths is there each hour ]

Answers

Answer:

57 deaths per hour

Step-by-step explanation:

In one year, we have 365 days.

Now, there are 24 hours in a day.

Thus,

Number of hours in one year = 365 × 24 = 8760 hours

Now, since there are half a million heart attacks deaths occurring in the United States of America each year, it means that;

There are 500000 deaths every 8760 hours.

Therefore, death rate per hour = 500000/8760 ≈ 57 deaths per hour

A letter about the evidence of evolution A manufacturing company produces 3 different products A, B, and C. Three types of components, i.e., X, Y, and Z, are used in the production of these products. One unit of product A requires 2 units of X, 2 units of Y, and 2 units of Z. One unit of product B requires 1 unit of X, 3 units of Y, and 2 units of Z. One unit of product C requires 1 unit of X, 2 units of Y, and 3 units of Z.Currently, the company has no existing inventory of the components. The company can purchase X at the price of $20 per unit but no more than 300 units due to the supplier's limited capacity constraint. The company can purchase Y at the price of $30 per unit without any upper limit. The company can purchase Z at the full price of $25 per unit for the first 100 units but the per unit price drops to $20 for the remaining units if any i.e., the purchase quantity in excess of 100 units). The market prices of the three products are $200 for A, $240 for B and $220 for C. The company knows that the demand for products A, B, and Care equal to 100, 80, and 90 units, respectively. Therefore, the company should not produce more than the demand for each product. However, the company incurs a per unit penalty of $40 for any unsatisfied demand. The company needs to decide the component parchase plan and the production mix decisions to maximize its profits subject to all the business constraints described above.
