Answer: 108

Step-by-step explanation: The 40% percent taken away from $270 would be $108, because I round it to 50% percent off and that would $135 but since it's 40% off not 50% so I took away 10% from $135, and that's how I found my answer .

Answer:

[tex]Length = 18[/tex]

[tex]Width = 27[/tex]

Step-by-step explanation:

Given

Dimension = 20 by 30

Reduction = 10%

Required

Determine the new dimensions

Because it is a reduction, the new dimension is calculated using:

[tex]New = Old (1 - Reduction)[/tex]

The new length is calculated as:

[tex]Length = 20(1 - 10\%)[/tex]

Convert percentage to decimal

[tex]Length = 20(1 - 0.10)[/tex]

[tex]Length = 20 * 0.90[/tex]

[tex]Length = 18[/tex]

The new width is calculated as:

[tex]Width = 30(1 - 10\%)[/tex]

Convert percentage to decimal

[tex]Width = 30(1 - 0.10)[/tex]

[tex]Width = 30*0.90[/tex]

[tex]Width = 27[/tex]

Step-by-step explanation:

The Mean Value of a Data Set

The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:

[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]

Where xi is the value of each data and n is the total number of values.

We are given the average weight of n=5 marathon runners:

[tex]\bar x=92[/tex]

Multiplying the formula by n and expanding the sum:

[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]

We are given the weighs of four of the runners:

[tex]5*92=89+95+90+90+x_5[/tex]

[tex]460=364+x_5[/tex]

Solving for x5:

[tex]x_5 = 460-364=96[/tex]

Answer:

A. 3 hours and 51 mins long

Step-by-step explanation:

22-13= 9 min difference

11-3=4 but since there is a 9 min difference it would be 9 mins away from 4 hours so that why is it 3 hours and 51 minutes long

Answer:

length=70cm

width=7cm

Step-by-step explanation:

total ratio=10 + 1

=11

length(2)=10/11 x 154 cm

=10 x 14cm

=140cm

one length is 140 cm/2=70cm

width(2)=1/11 x 154cm

=14cm

one width is 14cm/2=7cm

The length and the width should be considered as the 70 cm and 7 cm.

Since

The perimeter of a rectangle is 154 cm.

The ratio of the length to the width is 10: 1.

So here total ratio=10 + 1

=11

Now length 2 should be

=10/11 x 154 cm

=10 x 14cm

=140cm

So,

one length is 140 cm/2=70cm

Now

width(2)=1/11 x 154cm

=14cm

And,

one width is 14cm/2=7cm

hence, The length and the width should be considered as the 70 cm and 7 cm.

Answer:

The boat is approaching the dock  at 0.65 ft/sec when 13 feet of rope are out.

Step-by-step explanation:

Let x be the length of rope and y be the distance between boat and dock.

Height of point where a ring attached =z=5 feet

[tex]\frac{dx}{dt}=-0.6ft/sec[/tex]

x=13 feet

Using Pythagoras theorem

[tex]H^2=P^2+B^2[/tex]

[tex]x^2=z^2+y^2[/tex]

[tex]x^2=5^2+y^2=25+y^2[/tex]

[tex](13)^2=25+y^2[/tex]

[tex]169-25=y^2[/tex]

[tex]144=y^2[/tex]

[tex]y=12 feet[/tex]

Differentiate w.r.t t

[tex]2x\frac{dx}{dt}=2y\frac{dy}{dt}[/tex]

[tex]x\frac{dx}{dt}=y\frac{dy}{dt}[/tex]

[tex]13(-0.6)=12\frac{dy}{dt}[/tex]

[tex]\frac{7.8}{12}=\frac{dy}{dt}[/tex]

[tex]\frac{dy}{dt}=-0.65feet/sec[/tex]

Hence,the boat is approaching the dock  at 0.65 ft/sec when 13 feet of rope are out.

It would negative because 70 is a negative integer while 7 is positive and positive multiplied with negative is a negative

Answer:

The sign of the product is positive.

Step-by-step explanation:

Suppose, two negative integers are (-x) and (-y). Then their product will be xy which has a positive sign.

Again take two integers -x, -y and -z. Their product is -xyz.

It means, if positive number of negative integers are multiplied, the result is positive whereas the product of negative number of negative integers is negative.
