A rectangle has a perimeter of 600 cm. The width of the rectangle is 40 cm less than the length. What is the length of the rectangle, in cm?

Answer:

232°

Step-by-step explanation:

1. 180-52=128

2. 360-128=232

first you subtract 52 from 180 bc you have to get the angle not included for calculating the whole bearing bc the starting point is the north line. so everything before the north line is not valid bc when you're calculating an angle like this you go from lef to to right, clockwise. in every calculation of bearings you go clockwise. next you just subtract the product you got from 360 and that's it.

hope it didn't sound too complicated.

Answer:

[tex](\frac{1}{6}) ^{th}[/tex] of area

Step-by-step explanation:

Area occupied by Himalayan panda = [tex]\frac{2}{4}^{th}[/tex]  of area

Area occupied by Giant Panda = [tex]\frac{1}{6} ^{th}[/tex] of area

Area occupied by Albino panda = [tex]=\frac{2}{12} ^{th}[/tex]of area

Area occupied by brown Panda = [tex](1-\frac{2}{4}-\frac{1}{6}-\frac{2}{12}) ^{th}[/tex] of area

= [tex](\frac{12-6-2-2}{12} )^{th}[/tex] of area

= [tex](\frac{2}{12}) ^{th}[/tex]of area

= [tex](\frac{1}{6}) ^{th}[/tex] of area

Answer: 3/8

Step-by-step explanation: 3/8 is the answer

Answer:

a. 5

b. 3

c. 3

Step-by-step explanation:

Terms are variables, the number connected to the term is called the coefficient, the variable does not need a coefficient to be considered a term. There are 5 terms in a (9x,4y,7x,8w,t) 3 terms in b (Ab,3a,4b) and 3 terms in c (25a,9bc,8def).

Notice how there are multiple variables in sets b and c. Do not get confused into thinking these are multiple terms, they are one. A term is a single expression with one or more variables that are multiplied but never added or subtracted. Ex: abc is one term but 3 variables.

Answer:

33.3m^2

Step-by-step explanation:

If Jessica waxes 20 m^2 of the floor in 3/5 of an hour, then;

20m^2 = 3/5 hr

To get the area that she waxes in an hour

x = 1 hr

Divide both expression

20/x = 3/5

3x = 20 * 5

3x = 100

x =100/3

x = 33.3m^2

Hence she can wax 33.3m^2 in an hour

Answer:

x = 30

Step-by-step explanation:

Given the expression

-2/3 x - 1 =19

We are to find the value of x

Add 1 to both sides

2/3 x -1 +1 = 19+1

2/3 x =20

Multiply

2/3x × 3 = 20×3

2x = 60

x = 60/2

x = 30.

Hence the value of x is 30

Answer:

0

Step-by-step explanation:

Zero divided by any number is zero

Answer:

A

Step-by-step explanation:

Answer:

The maximum height is 46.64 feet.

Step-by-step explanation:

If we take the derivative of h whit respect to t and equal this to zero we would find the value of t which corresponds to the maximum h.

So, we have the function h(t):

[tex]h(t)=-16t^{2} + 45t + 15[/tex]

Taking the derivative, we have:

[tex]\frac{dh(t)}{dt}=-32t + 45=0[/tex]

Now, we solve it for t:

[tex]t=\frac{45}{32}=1.4\: s[/tex]

Finally, we put this value of t into the original equation.

[tex]h(t)=-16(1.4)^{2} + 45(1.4) + 15[/tex]

[tex]h_{max}=46.64\: ft[/tex]      

Therefore, the maximum height is 46.64 feet. All the given options are wrong, the one that comes closest is option A.

I hope it helps you!

Answer:

n < 7 (n must be strictly less than 7)

so 4 and 6.65 can make this statement true

Step-by-step explanation:

28 > 4n

solve as if it is a normal equation,

divide both sides by 4

n < 7

n must be less than 7

so 4 and 6.65 are values that make the statement true

Tommy earned $55

Step-by-step explanation:

Proportions

Tommy and Mark made $88 raking leaves for Mrs. Bopp. They were paid the same rate and Tommy raked for 5 hours while Mark raked for 3 hours.

The total time both raked is 5+3=8 hours. The rate Mrs. Bopp paid them was $88/8 = $11 per hour.

Tommy raked 5 hours, so he earned 5*$11 = $55

Tommy earned $55

Answer:

60% choose the Museum.

Step-by-step explanation:

Add the students who choose the museum and the students who choose the factory to get 95. You would then need to divide the amount of students who choose the museum by the total amount of students. Your answer would be 0.6, or 60%

60% of the students sixth-graders at Jen's school picked the museum.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, 57 sixth graders picked the museum and 38 sixth graders picked the factory.

So, the total no. of students is (57 + 38) = 95.

∴ The percentage of the sixth-graders who picked the museum is,

=  (57/95)×100%.

= 60%.
