What is the product of seven plus two and eight minus two

Answer:

10 + 5x ≤ 25

Step-by-step explanation:

Answer:

The value of the given expression is -4.5

Step-by-step explanation:

We need to find the value of the expression [tex]-3|5-s^3|+3t[/tex] when s=2 and t=1.5

Putting the values of s and t in the given expression.

So,

[tex]-3|5-s^3|+3t=-3|5-(2)^3|+3\times 1.5\\\\=-3|5-8|+4.5\\\\=-3|-3|+4.5[/tex]

We know that, |-a|=a

So,

[tex]=-3|-3|+4.5\\\\=-3(3)+4.5\\\\=-9+4.5\\\\=-4.5[/tex]

So, the value of the given expression is -4.5

Answer:

-13.5 is the correct answer.

Answer:

k = 10

Step-by-step explanation:

30+2k+5k=100

Combine like terms

30 + 7k = 100

Subtract 30 from each side

30+7k-30 = 100-30

7k  = 70

Divide each side by 7

7k/7 = 70/7

k = 10

Answer:

k=10

Step-by-step explanation:

We are given the equation:

30+5k+2k=100

We want to find k, therefore we must isolate k on one side of the equation.

First, combine like terms on the left side of the equation. 5k and 2k can be added together.

30+5k+2k=100

30+(5k+2k)=100

30+7k=100

30 is being added to 7k. The inverse of addition is subtraction. Subtract 30 from both sides of the equation.

30-30+7k=100-30

7k= 100-30

7k= 70

k is being multiplied by 7. The inverse of multiplication is division. Divide both sides by 7.

7k/7=70/7

k=70/7

k= 10

The solution to the equation 30+5k+2k=100 is k=10

Answer:

Step-by-step explanation:

Given,

diameter ( d ) = 12 in

height ( h ) = 15 in

finding the radius of a cylinder

Radius is just half of diameter.

Radius ( r ) = 12 / 2 = 6 in

finding the volume of a cylinder having radius of 6 in and height of 15 in

Volume of a cylinder = [tex] \sf{\pi \: {r}^{2} h}[/tex]

⇒[tex] \sf{ \frac{22}{7} \times {6}^{2} \times 15}[/tex]

Answer:

Step-by-step explanation:

Use PEMDAS rules

In this problem, according to PEMDAS , inner brackets should be solved the division and finally multiplication.

3[ (15 - 3)² ÷ 4]  = 3[(12)² ÷ 4]   {Now find the square of 12}

                         = 3[144 ÷ 4]    {Now do division}

                         =3 * 36       {Finally multiplication}

Explicación paso a paso:

Deje que el nivel del suelo del parque de atracciones sea cero. Si el túnel del miedo se eleva a una altura de 50 metros sobre el suelo, entonces la distancia desde el nivel del suelo hasta la altura de 50 m sobre el suelo será 50 + 0 = 50 m.

Del mismo modo, si el túnel cae 65 m en un túnel subterráneo, la distancia desde el nivel del suelo hasta la distancia de 65 m bajo tierra será de 65 m.

De ahí la diferencia entre la elevación del túnel y la del túnel subterráneo = 65 m - 50 m = 15 m

Answer: x³+2x²-22x+12

Step-by-step explanation:

the product of functions: (hg)(x)

Use FOIL to solve this (First Outer Inner Later)

 (x+6)(x²-4x+2)

=x³-4x²+2x+6x²-24x+12

Answer:

5 hourss

Step-by-step explanation:

197-32= 165

165/33

Answer:

5 hours

Step-by-step explanation:

Ralph earned $197 in total but with an initial fee of $32 so,

197 - 32 = 165

$165 is the amount he made from the hourly fee alone. So let's divide the total by the hourly fee.

165 ÷ 33 = 5.

So the job took 5 hours.

Answer:

97.35

Step-by-step explanation:

355.5 - 235.5 -22.65

I am subtracting 235.5 and 22.65  from 355.5 because I am spending that much money on the things.

=> 355.5 - 235.5 - 22.65

=> 120 - 22.65

=> 97.35 rupees

So, 97.35 rupees is left

Answer:

Step-by-step explanation:

y = 6x + 2

Slope = 6

A line perpendicular to this would have a negative reciprocal slope = [tex]-\frac{1}{6}[/tex]

To solve for the y-intercept, plug the coordinates given into the question.

y = mx + b

5 =[tex]-\frac{1}{6}[/tex] (3) + b

5 = [tex]-\frac{3}{6}[/tex] + b

5 = [tex]-\frac{1}{2}[/tex] + b

b = 5 + [tex]\frac{1}{2}[/tex]

b = [tex]\frac{11}{2}[/tex] or 5 [tex]\frac{1}{2}[/tex]

So, your new slope-intercept line equation is

y = [tex]-\frac{1}{6}[/tex]x + 5 [tex]\frac{1}{2}[/tex]

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. The majority of Earth's atmosphere (78%) is atmosphere nitrogen, making it the largest source of nitrogen. However, atmospheric nitrogen has limited availability for biological use, leading to a scarcity of usable nitrogen in many types of ecosystems.

Answer:

596

Step-by-step explanation:

closest to 600.

this means we can narrow the first digit of all 5he three digits to be either 5 or 6:

5_ _

or

6_ _

however, when considering the closest number to 600 when starting with 6, we realise that we can only make 630.

when looking at starting with 5, we can make 590, much closer to 600.

so now, we have deduced it has to become 590

however, we can use 3 digits. so, using a 6, the next highest number, we can confidently rest our case.

Answer:

593! \(-^0^-)/

Step-by-step explanation:

600 - 593 = 7

you will haave 7 to get to the humber 600!

Answer:

The decimal point should be placed between 9 and 7

i.e

269.70

Step-by-step explanation:

In Long division method, the formula is given as:

Dividend ÷ Divisor = Quotient

We were given

26.97 ÷ 6.3

26.97 = Dividend

6.3 = Divisor

We are told in the question that:

as long division set up where 63 is on the outside of the division symbol and 26970 is on the inside so that the divisor is written as a whole number,

This means, since the Divisor 6.3 is made into an whole number = 63

It means 6.3 was multiplied by 10

6.3 × 10 = 63

In Long division, whatever rule is applied to the Divisor must be applied to the Dividend.

Since 6.3 was multiplied by 10 = 63(whole number), then the dividend must be multiplied by 10

Dividend = 26.97 × 10 = 269.7

Therefore, the place where should the decimal point be placed in the dividend is between 9 and 7

= 269.70

Answer: Between the 9 and the 7

Answer:

Isaac worked 12 hours

Ruby worked 18 hours

Svetlana worked 72 hours

Step-by-step explanation:

Here in this question, we are interested in knowing the number of hours each person worked.

We proceed as follows;

Let the number of hours Isaac worked be x hours.

From the question, we are told that Ruby worked 6 hours more than Isaac

So the number of hours Ruby worked will be;

(x + 6) hours

Also;

Svetlana worked 4 times as many as Ruby:

This means that we have to multiply the number of hours Ruby worked by 4 to get the number of hours that Svetlana worked;

So the number of hours Svetlana worked will be : 4(x + 6) hours

Since the three worked a total of 102 hours, to get the number of hours each worked, we need to add together the number of hours each individual put in to work and equate to 102;

Mathematically, that would be;

x + x + 6 + 4(x + 6) = 102

2x + 6 + 4x + 24 = 102

6x + 30 = 102

6x = 102-30

6x = 72

x = 72/6

x = 12 hours

So Isaac worked x hours = 12 hours

Ruby worked (x + 6) hours = 12 + 6 = 18 hours

Svetlana worked 4(x + 6) hours = 4(18) = 72 hours

Answer:

6 weeks

Step-by-step explanation:

So the amount b we will have in our account w weeks from now is given by the equation:

[tex]b=85+(15+7)w[/tex]

To find out after how many weeks from now we will have $210, substitute 210 for b and solve for w:

[tex]210=85+(15+7)w[/tex]

Subtract 85 from both sides:

[tex]125=(15+7)w[/tex]

Add within the parentheses:

[tex]125=22w[/tex]

Divide both sides by 22:

[tex]w=125/22\approx5.68\approx6[/tex]

In other words, we will have $210 after approximately 6 weeks.

Answer:

6 hours

Step-by-step explanation:
