hi

The number of more people who felt a stabbing pain than a stomach ache when they are hungry is obtained by subtracting the number of people who felt a stomach ache from the number of people who felt a stabbing pain. The difference, which is 19, indicates that 19 more people felt a stabbing pain.

The subject of the question is simple subtraction in mathematics. In this scenario, find the difference between the number of people who felt a stabbing pain when they were hungry and the number who felt a stomach ache. The number of people who felt a stabbing pain is 49, and the number of people who felt a stomach ache is 30. So, to obtain the number of more people feeling stabbing pain than stomach ache: 49 (stabbing pain) - 30 (stomach ache) = 19. Thus, 19 more people felt a stabbing pain than a stomach ache when they were hungry.

Answer:

Step-by-step explanation:

(-7*4x)(-7*-3)

-28x+21

Thats the answer

To simplify the expression -7(4x-3), distribute -7 to each term inside the parentheses and multiply. The simplified expression is -28x + 21.

To simplify the expression -7(4x-3) using the distributive property, you need to distribute the -7 to each term inside the parentheses. This means multiplying -7 by both 4x and -3.

The product of -7 and 4x is -28x, and the product of -7 and -3 is 21.

Therefore, the simplified expression is -28x + 21.

Answer:

f(g(x)) = 72x^2+1

Step-by-step explanation:

f(x) = 2x^2 +1

g(x) = -6x

f°g(x) means f(g(x))

Take g(x) and substitute it in for x in f(x)

f(g(x)) = 2(g(x))^2 +1

           =2(-6x)^2 +1

          =2(36x^2) +1

           =72x^2 +1

Answer: I could be wrong so don't get your hopes up but I believe the solution set would be {-2,12}

Step-by-step explanation:

Answer:

The solution set is {-12,2}.

Step-by-step explanation:

We have given a quadratic equation.

x² + 10x = 24

We have to find the solution of above equation by completing square.

Adding (5)² to both sides of above equation, we have

x²+10+(5)²  = 24+ (5)²

(x+5)² = 24+25

(x+5)² = 49

Taking square root to both sides of above equation, we have

x+5 = ±7

x+5 = 7 or x+5 = -7

x = 7-5 or x = -7-5

x = 2 or  x = -12

Hence, the solution set is {-12,2}.

Answer:

A. $1,110

B. 50 units.

Step-by-step explanation:

A. Substitute [tex]x=18[/tex] into the function [tex]T(x)=4x+2[/tex] for calculate the time in hours required for the worker to produce 18 units:

[tex]T(18)=4(18)+2=74[/tex]

Now you need to substitute [tex]T=74[/tex] into the function [tex]S(T)=15T[/tex] to calculate the amount in dollars she will be paid for 74 hours:

[tex]S(74)=15(74)=1,110[/tex]

She will be paid $1,110.

B. To calculate the number of units that the worker needs to produce to be paid $3,030 , you need to substitute [tex]S(T)=3,030[/tex] into the function [tex]S(T)=15T[/tex] and solve for T (to find the number of hours she requires to work to be paid $3,030)

[tex]3,030=15T\\\\T=\frac{3,030}{15}\\\\T=202[/tex]

Now, substitute [tex]T(x)=202[/tex] into [tex]T(x)=4x+2[/tex] and solve for x, to calculate the number of units she produces in 202 hours:

[tex]202=4x+2\\\\202-2=4x\\\\x=\frac{200}{4}\\\\x=50[/tex]

She would need to produce 50 units to be paid $3,030

To find the surface area, find the area of each side and then add them together.

The bottom is 8 x 2 = 16

The left side is 6 x 2 = 12

The slanted side is 10 x 2 = 20

The front triangle is  1/2 x 8 x 6 = 24

The back triangle is the same as the front = 24

Total surface area = 16 + 12 + 20 + 24+24 = 96 square inches.

Volume of a cylinder: V = πr^2h

Answer:

3580 ft³

Step-by-step explanation:

The formula for the volume of a cylinder is

V = πr²h

Data:

r = 10 ft

h = 11.4 ft

Calculations:

V = πr²h = 3.14 × 10² × 11.4 = 3580 ft³

The approximate volume of the cylinder is 3580 ft³.

The answer is twelve.

3/4 x 4 = 12/16

12/16 divided by 1/16 is 12z

Answer:

The answer is 1/4 Also if your having a hard time with fractions use calculator soup its easy thats what i use

Step-by-step explanation:

The simplest form of the expression 1/2 - 1/4 is 1/4.

To simplify the expression 1/2 - 1/4, we first need to find a common denominator, which is the same denominator that both fractions share. In this case, the common denominator is 4.

To make 1/2 have a denominator of 4, we need to multiply both the numerator and denominator by 2. This gives us (1 * 2) / (2 * 2), which simplifies to 2/4.

So, the expression becomes 2/4 - 1/4. Now that both fractions have the same denominator, we can subtract their numerators while keeping the denominator the same:

(2 - 1) / 4 = 1/4

Therefore, the simplified form of 1/2 - 1/4 is 1/4. This means that if you have half (1/2) of something and you subtract a quarter (1/4) from it, you are left with one-quarter (1/4) of that something.

Simplifying fractions is essential in mathematics because it helps express quantities in their most reduced and straightforward forms, making them easier to work with and understand. In this case, 1/2 - 1/4 simplifies to 1/4, representing a clear and concise result.

A rhombus is a simply a diamond. Think about the visual properties of a diamond. Isn't a kite a diamond?

Answer: True.

Step-by-step explanation:

In geometry , we have three undefined terms as :

1) point      [ no dimension]

2) line        [ one dimension]

3) plane     [ two dimension]

A point is just a tiny mark on Cartesian plane which has no length like a line , no width and area like a plane or no volume like a three dimensional shape . We can use only its location but cannot measure it.

Hence, it has no dimension.

Hence, the given statement "a point occupies zero dimensions" is a true statement.
