can someone pls help?

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]

Answer:

A. 3 hours and 51 mins long

Step-by-step explanation:

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:

The correct answer is A

Step-by-step explanation:

A is correct because you divide 23 and 3 to equal 7 then you do 7 times 3 to equal 21 cups meaning you have enough pecans to make 7 pies and 2 cups of pecans left over.

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.

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:

for the second column it is 12.5

for the third column it is 20%

for the fourth column it is 120%

for the fifth column it is 33%

for the sixth column it is 11.35

for the seventh column it is 900

for the 8th column it is 60%

for the final column it's 39

Step-by-step explanation:

Answer:

percent proportion....... percent equation

1. $26...........x = 6.5×400/100

2.$12.5.........x = 12.5×100/190

3.20%..........x = 130×100/650

4.120% ..........x = 5.40×100/4.50

5.30%...........x = 8.4×100/28

6.$39....…......x = 21.84×100/56

7.$900.….......x = 495×100/55

8.60%….....….x = 144×100/240

9.30%............ x 120×100/400

10.$39.............x = 975×4/100

Answer:

x ≈ 14.6

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos40° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{19}[/tex] ( multiply both sides by 19 )

19 × cos40° = x , then

x ≈ 14.6 ( to the nearest tenth )

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.
