Solve the equation below :

7/8 = q + 1/2

A : q = 3/8


B : q = 1 3/8


C : q = 7/16


D q = 1 3/4

Answers

Answer 1

Answer:

q = -3/8

Step-by-step explanation:

Clearing out the fractions first simplifies this problem.  The LCD here is 8, so we multiply all three terms of 7/8 = q + 1/2 by 8 and simplify the result:

7 + 8q = 4.  

Combining the constants, we get:  8q = 4 - 7, or 8q = -3.

Finally, solve for q:

q = -3/8

Mrs. Santiago's consumer science class is making two different-size cheesecakes for
a fundraiser.
The large cheesecake has a diameter of 12 inches
The small cheesecake has a diameter of 4 inches
Part A: If the pans are both 3 inches deep, how many times greater is the volume
Of the large pan than that of the small pan? Show your work
Part B: When shipped, the large cheesecakes will be packaged in a box with dimensions of 12 in x
12 in x 3 in. What percentage of the box does the large cheesecake take up?
Show all work for each part and give at least 2 sentences explaination for each part.

Answers

Answer:

Part A: 9 times

Part B: 79%

Step-by-step explanation:

Part A:

Volume of the large pan = πr²h

Where,

radius (r) = ½(diameter) = ½(12) = 6 in.

height (h) = 3 in.

Volume = π*6²*3

Volume of the large pan = 339.29 in.³

Volume of the small pan = πr²h

r = ½(4) = 2 in.

h = 3 in

Volume of small pan = π*2²*3

Volume of the small pan = 37.7 in.³

✔️To determine how many times the volume of the large pan is greater than the small pan, divide the volume of the larger by the smaller:

= 339.29/37.7 ≈ 9

✅The volume of the large pan is about 9 times greater than the volume of the smaller pan.

Part B:

✔️Find the volume of the box:

Volume of box = L*W*H

Where,

L = 12 in.

W = 12 in.

H = 3 in.

Volume of the box = 12*12*3 = 432 in.³

Divide the volume of the large pan over the volume of the box and multiply by 100%

Thus:

339.29/432 × 100

= 78.5393519 ≈ 79%

The large cheesecake takes up about 79%

that a child has side effects. Draw a conclusion based on your results.

Answers

Answer:

the answer is 0.40 and 0.12 children have much greater chance of having side effects than adults mark me brainiest

Step-by-step explanation:

The correct option is P(side effects | child) = 0.40 and P(side effects | adult) = 0.12. Conclusion is Children have a much higher chance of having side effects than adults.

Total number of people tested = 100

Number adults = 50

Number of adults who got side effects = 6

Probability that the adult got side effects = 6/50 = 0.12

Number of children = 50

Number of children who got side effects = 20

Probability that the children got side effects = 20/50 = 0.40

Here, it is clear that probability that the children got side effects is greater than that adult got side effects.

So, Children have a much higher chance of having side effects than adults.

3 = -2 |.25s - 5| +3​

Answers

Answer:

s = 20

Step-by-step explanation:

Given

3 = - 2 | 0.25s - 5 | + 3 ( subtract 3 from both sides )

0 = - 2 | 0.25s - 5 | ( divide both sides by - 2 )

0 = | 0.25s - 5 | , then

0.25s - 5 = 0 ( add 5 to both sides )

0.25s = 5 ( divide both sides by 0.25 )

s = 20

Answer: S=20

Step-by-step explanation:

Data: 3=-2(0.25s-5)+3

S=?

Step one, Multiply .25s and -5 by -2

-2x0.25s=-0.50s

-2x-5=10

Reason: When something is in parenthesis, that is the first thing you evaluate, and since -2 is right next to the parenthesis, you multiply both numbers by -2 to get -.50s and 10

Step two, add like terms

3=-.50s+10+3=3=-.50s+13

Reason: When there are like terms(terms with the same variable or same exponent, etc.) You have to add them or else evaluating things will get harder to do as you go on, in this case, the two like terms(3 and 10) added together get 13.

Step three, subtract 13 on both sides

3-13=-.50s+13-13

-10=-.50s

Reason: Because the point of this is to single out 's', you have to get rid of the 13 and since it's a positive 13, you add it to a negative to cancel it out, but what you do to one side you do to the other so you subtract 13 from 3 to get negative 10.

Step four, divide -.50 on both sides

-10/-.50=-.50s/-.50

S=20

Reason: Since you have to isolate 's' and it's right next to -.50(which means multiplication), you have to divide it to get rid of it. Since what you do to one side you do to the other, you divide -10 by -.50 to get 20=S

That's how you get the answer

ft?. (Type an exact answer in terms of t.)

Answers

Step-by-step explanation:

the answer is in the above image

Answer:  1024pi

======================================================

Explanation:

The diameter 32 cuts in half to 16, which is the radius. So r = 16.

Use this to find the surface area of the sphere in the formula below

SA = 4*pi*r^2

SA = 4*pi*16^2

SA = (4*16^2)*pi

SA = 1024pi

This is the exact surface area in terms of pi.

A circle is defined by the equation below:

x^2 + y^2 - x - 2y - 11/4 = 0

What are the coordinates for the center of the circle and the length of the radius?

Answers

Answer:

Step-by-step explanation:

We know that the equation of a circle is:

(

x

a

)

2

+

(

y

b

)

2

=

R

2

where a and b are the coordinates of the center, and R is the radius.

So in this question we have to complete the squares:

x² + y² - x - 2y - 11/4 = 0       ->

x² - x + 1/4 + y² - 2y = 11/4 +1/4     ->

(x - 1/2)² + y² - 2y + 1 = 12/4 + 1     ->

(x - 1/2)² + (y - 1)² = 4

Therefore, the coordinates of the center are C = ( 1/2, 1) and the Radius is R = 2

      x² + y² - x - 2y - 2³/₄ = 0

               x² + y² - x - 2y = 2³/₄

               x² - x + y² - 2y = 2³/₄

(x² - x + 1) + (y² - 2y + 4) = 2³/₄ + 1 + 4

             (x - 1)² + (y - 2)² = 7³/₄

The coordinates for center of the circle is equal to (1, 2). The coordinates of the length of the radius is √(³¹/₄).

1. The equation is of the form , where a, b, and c are all positive integers and . Using this equation as a model, create your own equation that has extraneous solutions. (a) Using trial and error with numbers for a, b, and c, create an equation of the form , where a, b, and c are all positive integers and such that 7 is a solution. (Hint: Substitute 7 for x, and choose a value for a. Then square both sides so you can choose a, b, and c that will make the equation true.) (b) Solve the equation you created in Part 2a. (c) If your solution in Part 2b did not have an extraneous solution, revise your equation so that 7 is one solution and there is an extraneous solution. If your solution in Part 2b did have an extraneous solution, create another equation with different values of a, b, and c that also has 7 as one solution and an extraneous solution.

Answers

Answer:

[tex]7 + a = \sqrt{7b + c}[/tex] --- equation

[tex]a = 3; b =5\ and\ c = 65[/tex] --- the equation is true for these values

[tex]a = 4; b=5\ and\ c = 10[/tex] --- the equation is extraneous for these values

Step-by-step explanation:

Given

[tex]x +2 = \sqrt{3x + 10[/tex]

[tex]x + a = \sqrt{bx + c}[/tex]

Solving (a): Equation to solve for a, b and c, using trial by error where [tex]x = 7[/tex]

We have:

[tex]x + a = \sqrt{bx + c}[/tex]

Substitute 7 for x

[tex]7 + a = \sqrt{7b + c}[/tex] --- This is the equation

Solving (b): Solve for a, b and c --- to make the equation true

[tex]7 + a = \sqrt{7b + c}[/tex]

Let a = 3 ----- Here, we choose a value for a

[tex]7 + 3 = \sqrt{7b + c}[/tex]

[tex]10 = \sqrt{7b + c}[/tex]

Square both sides

[tex]100 = 7b + c[/tex]

Let b = 5 --------- Here, we choose a value for b

[tex]100 = 7*5 + c[/tex]

[tex]100 = 35 + c[/tex]

Subtract 35 from both sides

[tex]c = 65[/tex]

So, [tex]x + a = \sqrt{bx + c}[/tex] is true for

[tex]a = 3; b =5\ and\ c = 65[/tex]

Solving (b): Solve for a, b and c --- to make the equation false

[tex]7 + a = \sqrt{7b + c}[/tex]

Substitute [tex]a = 4; b=5\ and\ c = 10[/tex]

So, we have:

[tex]7 + 4 = \sqrt{7*5 + 10}[/tex]

[tex]11 = \sqrt{35 + 10}[/tex]

Square both sides

[tex]121 = 45[/tex] --- This is false

i.e.
