Blake can paint a room in 9 hours, Ned can paint the same room in 6 hours, how long to paint the room together

Answers

Answer 1
Work done by Blake = 1/9; Work done by Ned = 1/6; Total work done by both of them together is given by 1/6 +1/6 = 3+2/18 = 5/18; So, the time taken by both of them if they work together is given by: 18/5 =3 3/5 hours.

Joe measured the diameter of a tennis ball correct to the nearest millimetre. The upper bound of his measurement was 6.75 centimetres. Write down, in imillimetres, the lower bound of his measurement.​

Answers

The lower bound of the measurement is 65.5 millimetres.

A centimetre equals 10 millimetres, a measure is expressed by the measured magnitude plus uncertainty, the latter one represents the grade of precision of the measure instrument. That is to say:

[tex]y = x + \epsilon[/tex] (1)

Where:

[tex]x[/tex] - Measured magnitude, in millimeters.[tex]y[/tex] - Possible magnitude, in millimeters.[tex]\epsilon[/tex] - Uncertainty, in millimeters.

If we know that [tex]y = 67.5\,mm[/tex] and [tex]\epsilon = 1\,mm[/tex], then the lower bound of the measurement is:

[tex]y = 67.5\,mm - 2\cdot (1\,mm)[/tex]

[tex]y = 65.5\,mm[/tex]

The lower bound of the measurement is 65.5 millimeters.

Answers

Answer:

Step-by-step explanation:

ZTU = 75, since RTS and ZTU are vertical angles, and RTS = 75.

TZU = 43, since TZU and QZX are vertical angles, and QZX = 43.

ZUT = 180 - ZTU - TZU = 180 - 75 - 43 = 62, since triangle ZUT is shown in the diagram, and the sum of its interior angles = 180.

YUW = 180 - 79 - 62 = 39, since TUW is a straight angle, which measures 180 degrees, and angle TUW is the sum of angle ZUY and angle ZUT and angle YUW, by the diagram.

YVU = 180 - ZUY - YUW = 180 - 68 - 39 = 73, since triangle YUV is shown in the diagram, and the sum of its interior angles = 180.

YVW = 180 - YVU = 180 - 73 = 107, since YVW and YVU are supplementary.

Now,

Since, The expression is,

⇒ (24m + 36) + (12m + 18)

it can be written as;

⇒ (24m + 36) + (12m + 18) = 12 (2m + 3) + 6 (2m + 3)

Thus, The equivalent expression after solving,

Ahmed bought 5 equally priced markers for $3.25.

How much will 12 of these markers cost?


$1.35

$6.68

$7.80

$8.46

Answers

Answer:

$7.80

Step-by-step explanation:

Find the unit price by dividing 3.25 by 5.

3.25 ÷ 5 = 0.65

Now that you have the unit price, multiply it by 12 to find the total price of the 12 markers.

0.65 × 12 = 7.80

Thus, 12 of the same markers that Ahmed bought will cost $7.80.

The cost of 12 markers is given by the equation A = $ 7.80

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the number of markers be n = 5

The cost of 5 markers = $ 3.25

So , the cost of 1 marker = cost of 5 markers / 5

On simplifying the equation , we get

The cost of 1 marker = 3.25 / 5

The cost of 1 marker = $ 0.65

Now , the cost of 12 markers = 12 x cost of 1 marker

Substituting the values in the equation , we get

The cost of 12 markers A = 12 x $ 0.65

The cost of 12 markers A = $ 7.80

Hence , the equation is A = $ 7.80 , where A is the total cost of markers
