[tex] \huge \orange { \boxed{x = \frac{c - k}{12} }}[/tex]

Step-by-step explanation:

12x + k = c

Step 1: transfer k on right side

12x = c - k

Step 2: Divide both side by 12

[tex] \frac{12x}{12} = \frac{c - k}{12} \\ \huge \red{ \boxed{x = \frac{c - k}{12} }}[/tex]

Answer:

He used an incorrect time ratio converting hours to minutes.

He incorrectly concluded that she is not running fast enough.

I dont really know how to give an explanation in detail but the answer is 32.40

5400 x .06 x 1

(turn the percent into a decimal)

The interest should be paid for 1 year is $324.

The formula for Simple Interest

SI = ( PRT)/100

where, P- Principal

R- Rate

T- Time

Given:

P = $5400

R= 6%

T= 1 year

So, Simple Interest

= PRT/100

= 5400 x 6 x 1 /100

= $324

Hence, the interest should be paid for 1 year is $324.

Answer:

($) 60 is the profit per item when the selling price is reduced by 20%

Step-by-step explanation: 20% of 700 is 140.

The original profit is 700 - 500 = 200. The selling price is 140 less, Subtract 140 from 200. That leaves a profit of 60. (Not necessarily dollars, as the currency was not given in the question.)

Answer:

The pitcher plant's approximate volume is 24.492 [tex]\text{cm}^{3}[/tex].

Step-by-step explanation:

We are given that a  pitcher is shaped like a cylinder with a radius of 1 centimeter and a height of 7.8 cm.

Let the radius of a cylinder = r = 1 cm

and the height of a cylinder = h = 7.8 cm

As we know that the volume of a cylinder is given by;

The volume of a cylinder = [tex]\pi r^{2}h[/tex]

                           = [tex]3.14 \times 1^{2} \times 7.8[/tex]  {taking approximate value of [tex]\pi[/tex] to be 3.14}

                           = [tex]3.14 \times 7.8[/tex]

                           = 24.492 [tex]\text{cm}^{3}[/tex]

Hence, this pitcher plant's approximate volume is 24.492 [tex]\text{cm}^{3}[/tex].

Answer:

a) (x, y) = (1, 7)

Step-by-step explanation:

Let be the following system of inequalties:

[tex]y > x^{2}-4\cdot x -5[/tex]

[tex]y < -x^{2}-5\cdot x +6[/tex]

We can find the right option by evaluating each option in the system of inequalities:

a) (x, y) = (1, 7)

[tex]7 > 1^{2}-4\cdot (1) -5[/tex]

[tex]7 < -1^{2}-5\cdot (1) +6[/tex]

Then,

[tex]7>-8[/tex] (TRUE)

[tex]7<0[/tex] (FALSE)

(1, 7) is not a solution of the system of inequalities.

b) (x, y) = (1, -7)

[tex]-7 > 1^{2}-4\cdot (1) -5[/tex]

[tex]-7 < -1^{2}-5\cdot (1) +6[/tex]

Then,

[tex]-7 > - 8[/tex] (TRUE)

[tex]-7< 0[/tex] (TRUE)

(1, -7) is a solution of the system of inequalities.

c) (x, y) = (1, -5)

[tex]-5 > 1^{2}-4\cdot (1) -5[/tex]

[tex]-5 < -1^{2}-5\cdot (1) +6[/tex]

Then,

[tex]-5 > - 8[/tex] (TRUE)

[tex]-5< 0[/tex] (TRUE)

(1, -5) is a solution of the system of inequalities.

d) (x, y) = (-1, 6)

[tex]6 > (-1)^{2}-4\cdot (-1) -5[/tex]

[tex]6 <(-1)^{2}-5\cdot (-1)+6[/tex]

Then,

[tex]6>0[/tex] (TRUE)

[tex]6 < 12[/tex] (TRUE)

(-1, 6) is a solution of the system of inequalties.

Therefore, we conclude that correct answer is A.

Answer:

11y-2x= -90

Step-by-step explanation:

for the point (1,-8)

x=1 and y= -8

for the equation,

2x -4y= -11

x= -1/m

m= -1/x

x = -1/ (-11/2 )

m= 2/11

so for the equation,

y-y1= m(x- x1)

y- -8=2/11(x-1)

11(y+8)= 2(x-1)

11y +88= 2x-2

11y-2x= -90

Step-by-step explanation:

relation is a function if we have y for every x from domain and for one x we have one and only one y

no x-es without y-es

and no two the same x-es with one y

so this relation is a function

Answer: 8

Step-by-step explanation:

Ok, el volumen de un cubo de lado L es:

V = L^3

Entonces, el volumen de un cubo de 1cm por lado es:

V = (1cm)^3 = 1cm^3

Y el volumen de cubo cuyos lados miden 2cm es:

V' = (2cm)^3 = 8cm^3.

Ahora, la cantidad de cubos chicos que van a entrar en el cubo grande es igual al cociente entre sus volúmenes:

V'/V  = (8cm^3)/(1cm^3) = 8

Entran 8 cubos de 1 cm por lado en un cubo de 2cm por lado.

Answer:

________________

I think it may be 31%

Answer:

50%

Step-by-step explanation:

There are a total of 640 fries.

40% of them are crispy. Therefore, let C be the amount of crispy fries:

[tex]C=0.4(640)=256[/tex]

Thus, the amount of soggy fries S would be:

[tex]S=640-256=384[/tex]

The total of the crispy fries and the soggy fries is the sum of the fries not on the floor and on the floor. Let F denote on the floor and let NF denote not on the floor. Thus:

[tex]C=C_F+C_{NF}[/tex]

C is 256:

[tex]256=C_F+C_{NF}[/tex]

Same thing for soggy fries S:

[tex]S=S_F+S_{NF}\\[/tex]

S is 384, thus:

[tex]384=S_F+S_{NF}[/tex]

We are told that 80% of the soggy fries are on the floor. Therefore:

[tex]S_F=0.8(384)=307.2[/tex]

This means that the amount of soggy fries not on the floor is:

[tex]S_{NF}=S-S_F\\S_{NF}=384-307.2=76.8[/tex]

We are given that 32% of all the fries are not on the floor. Therefore:

[tex]NF=0.32(640)=204.8[/tex]

The total amount of fries not on the floor is the sum of the amount of crispy fries and soggy fries not on the floor. Thus:

[tex]NF=C_{NF}+S_{NF}[/tex]

We know that NF is 204.8 and that S(NF) is 76.8. Substitute:

[tex]204.8=C_{NF}+76.8[/tex]

Subtract 76.8 from both sides:

[tex]C_{NF}=128[/tex]

This means that out of the 256 crispy fries, only 128 of them are not on the floor.

This means that the amount on the floor is 256-128, or also 128.

Thus, the percentage of crispy fries on the floor is:

[tex]=\frac{128}{256}=50%[/tex]

Our answer is 50%

Answer:

Look at the step by step

Step-by-step explanation:

3 cans of soup: 1500 mg of sodium

4 frozen dinners: 2600 mg of sodium

together they are 4100 mg of sodium

How many milligrams of sodium are there in  c cans of soup: [tex]500c[/tex]

How many milligrams of sodium are there in  f frozen dinners: [tex]650f[/tex]

There is 4100 mg of sodium together in 3 cans and 4 frozen dinner. 500c milligrams of sodium is there in  c cans of soup and 650f milligrams of sodium is there in f frozen dinners

An expression is combination of variables, numbers and operators.

Each can of soup has 500 mg of sodium and

each frozen dinner has 650 mg of sodium

1 can =500mg

frozen dinner = 650 mg

3 cans=3(500)=1500 mg

4 frozen dinner = 4(650) mg=2600 mg

Together there is 1500+2600= 4100 mg of sodium

500c milligrams of sodium is there in  c cans of soup

650f milligrams of sodium is there in  f frozen dinners

Hence, there is 4100 mg of sodium together in 3 cans and 4 frozen dinner. 500c milligrams of sodium is there in  c cans of soup and 650f milligrams of sodium is there in f frozen dinners

Step-by-step explanation:

Answer:

0.140 is represented using 40 thousandth blocks and 100 hundredth blocks

Step-by-step explanation:

Base 10 blocks are blocks in set of four which can be used together to represent any number. Also base 10 blocks can be used to perform mathematical computations like addition, subtraction, addition, division, area and many more.

We have to represent 0.140 using hundredths and thousandths blocks.

0.140 = 140 × 10⁻³ = 40 × 10⁻³ + 100 × 10⁻²

10⁻³ represents the thousandth block and 10⁻² for the hundredth. Hence:

0.140 = 140 × 10⁻³ = 40 × 10⁻³ + 100 × 10⁻²  = 40 thousandth + 100 hundredth

0.140 is represented using 40 thousandth blocks and 100 hundredth blocks
