i got the question right

The inequality that describes the situation is of:

[tex]3.25 + 5.5S \leq 30[/tex]

------------------------

[tex]T = 3.25 + 5.5S[/tex]

[tex]T \leq 30[/tex]

Answer:

No, mn is not even if m and n are odd.

If m and n are odd, then mn is odd as well.

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

Proof:

If m is odd, then it is in the form m = 2p+1, where p is some integer.

So if p = 0, then m = 1. If p = 1, then m = 3, and so on.

Similarly, if n is odd then n = 2q+1 for some integer q.

Multiply out m and n using the distribution rule

m*n = (2p+1)*(2q+1)

m*n = 2p(2q+1) + 1(2q+1)

m*n = 4pq+2p+2q+1

m*n = 2( 2pq+p+q) + 1

m*n = 2r + 1

note how I replaced the "2pq+p+q" portion with r. So I let r = 2pq+p+q, which is an integer.

The result 2r+1 is some other odd number as it fits the form 2*(integer)+1

Therefore, multiplying any two odd numbers will result in some other odd number.

------------------------

Examples:

So there is no way to have m*n be even if both m and n are odd.

The general rules are as follows

The proof of the other two cases would follow a similar line of reasoning as shown above.

BUT WHERE IS EQUATIONS. THEN HOW CAN I HELP YOU.???

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Or just subtract

Answer:

-6/7p + 1/7

Step-by-step explanation:

Like Terms: terms that have the same variables and powers

In this equation the like terms are -4/7p and -2/7p

First solve that, which will be -6/7p + 1/7

You have to leave the 1/7 alone because there aren't any more numbers with no variables.

Answer:

Step-by-step explanation:

You can only combine terms that are the same, which means you can only combine the fractions with p attached. A + and - make a -. The second fraction changes to negative or subtraction which ever way you want to say it.  -4 - 2 = -6 and the bottom number always stays the same  and you keep the letter attached. You can not combine 1/7 because it does not have a p attached. You would leave it the same. [tex]\frac{-6}{7}p +\frac{1}{7}[/tex]

43,000: 4.3×10^4

0.0072: 7.2×10^-3

0.0000901: 9.01×10^-5

Step-by-step explanation:

scientific notation: a×10^b, where should be 0<a<10

Step 1. Count the zeros

Step 2. Look at the number left, and determine whether or not it fits in the range of [a]. If not, we divide or multiply 10 to get it fit

------------------------

43,000: 4.3×10^4 (since 43 does not fit, we divide by 10 to get it fit)

0.0072: 7.2×10^-3 (since 0.72 does not fit, we multiply 10 to get it fit)

0.0000901: 9.01×10^-5 (since 0.901 does not fit, we multiply 10 to get it fit)

Answer:

just use the formula

Answer:

a) By multiplying   the length of the shadow of the tower to the ratio of the height of the exposed pencil placed in the ground to the length of the  pencil's shadow the height of the tower can be found

b) Height of the tower = Level to which the clinometer was raided + length of the shadow of the tower × tan (Angle of elevation of the top of the tower)

Step-by-step explanation:

a) The steps to measure the length of height of the tower using similar triangles are as follows;

Whereby the ground over which the tower is located is flat, place the pencil in the ground and ensure that it is upright and standing on its own

1) Measure the length of the shadow of the pencil

2) Measure the height of the exposed (above the ground) pencil

3) Find the ratio of the height of the exposed pencil to the length of the  pencil's shadow

4) Measure the length of the shadow of the tower

5) Multiply the length of the shadow of the tower to the ratio of the height of the exposed pencil to the length of the  pencil's shadow to find the height of the tower

b) To measure the height of the tower by trigonometry and the materials they have, we have;

1) Measure the length of the shadow of the tower using the measuring tape. Record the length as l

2) From the end of the length of the shadow of the tower, measure the angle of elevation of the top of the tower using the clinometer. Record the angle of elvation as θ

3) Measure the distance from the ground the clinometer was raised to measure the height of the shadow and record it as H₁

The height of the tower can then be found by the following formula;

Height of the tower, h = H₁+ length of the shadow of the tower × tan(θ)

h = H₁ + l × tan(θ)

Answer:

7 , 8 , 9

Step-by-step explanation:

Assume three consecutive number are,

x , (x+1) , (x+2)

Multiplied by 2 ,3 and 4 respectively

2x , 3(x + 1) , 4(x + 2)

Sum of all = 74

So,

2x + 3(x + 1) + 4(x + 2) = 74

2x + 3x + 3 + 4x + 8 = 74

9x + 11 = 74

9x = 63

x = 7

So,

x , (x+1) , (x+2)

7 , (7+1) , (7+2)

Answer: 8 days.

Step-by-step explanation:

Given that Anna can do a job in 4 days. After she has worked for 1 day, she is joined by Sylvia, and it takes them 2 days working together to finish the job.

Since Anna has already worked for 1 day, she would have worked the remaining days for 3 days. But she is joined by Sylvia, and it takes them 2 days working together to finish the job.

That is,

1/3 + 1/S = 1/2

Where S is the number of days Sylvia to do the job being completed in 2 days.

1/S = 1/2 - 1/3

1/S = (3 - 2)/6

1/S = 1/6

S = 6

The job Anna would have done for 3 days, will take 6 days for Sylvia.

The 1 days used by Anna will be 2 days for Sylvia.

Therefore, the total days that will take Sylvia to do the whole job by herself will be 2 + 6 = 8 days

Answer: To find the perimeter of a shape, we need to add the value of all of the sides. Here, we are given the values:

6cm

20cm

26cm

30cm

36cm

42 cm

All of these added together are equal to 160, so the perimeter of the shape is 160cm.

Answer:

perimeter = 160 cm

Step-by-step explanation:

perimeter = add all sides

perimeter = 6 + 20 + 26 + 30 + 36 + 42

perimeter = 160 cm

Irrational numbers are real numbers, they just aren't rational.

For example:

3.55555... and 4.31524363....

Answer:

A real number that can NOT be made by dividing two integers (an integer has no fractional part). "Irrational" means "no ratio", so it isn't a rational number. ... Example: π (the famous number "pi") is an irrational number, as it can not be made by dividing two integers.

The opposite of a number is simply the number multiplied by -1 so the opposite of n is -n. "Between -3 and 0" tells us that the inequality is -3 < -n < 0.

Answer:

The distance from the centre of the dome is 2000 feet

Step-by-step explanation:

We have an equation representing the distance from the centre of the dome.

We can now make the subject of the formula.

d = 2100 -2(h)

We are asked to find the value of d when the value of h is = 50 feet.

To do this, we simply plug in the value for h into the equation and solve the equation.

d = 2100 - 2(50)

d = 2100 -100

d = 2000 feet.

Hence the distance from the centre of the dome is 2000 feet

Answer:

Beto and Mark

Step-by-step explanation:

To know which of the equations written by the four students has no solution, let's try to solve each.

Beto's equation:

[tex] 3m = 3m + 5 [/tex]

[tex] 3m - 3m = 3m + 5 - 3m[/tex]

[tex] 0 = 5 [/tex] (This is incorrect. 0 ≠ 5. This is not a solution)

Lila's Equation:

[tex] 9r + 4 = 4 + 9r [/tex]

[tex] 9r + 4 - 9r = 4 + 9r - 9r [/tex]

[tex] 4 = 4 [/tex] (this is correct)

Mark's equation:

[tex] 6 - n = -n + 2 [/tex]

[tex] 6 - n + n = -n + 2 + n [/tex]

[tex] 6 = 2 [/tex] (incorrect. 6 ≠ 2)

Wanda's Equation:

[tex] 8u - 2 = 2u + 8 [/tex]

[tex] 8u - 2 + 2 = 2u + 8 + 2 [/tex]

[tex] 8u = 2u + 10 [/tex]

[tex] 8u - 2u = 2u + 10 - 2u [/tex]

[tex] 6u = 10 [/tex]

[tex] \frac{6u}{6} = \frac{10}{6} [/tex]

[tex] u = \frac{5}{3} [/tex]

If you plug in the value of u into the original equation, the equation would be balanced. Therefore, this is a solution.

Beto and Mark we equations that have no solution.
