The length of a rectangle 5 cm more than its width. If the area of the rectangle is 50 cm2
,
find the dimensions of the rectangle.
Answers
Answer:
the length is 10
the width is 5
Step-by-step explanation:
Hey there!
To solve this equation we use the formula
50=5/x
step 1 divide each side by 5
50/5=10
so we can conclude that x (or the width) = 5
then we add 5 (because the length is 5 more then the width)
5+5=10
so length =10 and width = 5

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 reds?
Answers
Answer: The probability of getting two red marbles is P = 0.141
Step-by-step explanation:
We know that in the bag there are 3 blue marbles and 5 red marbles, then there is a total of 8 marbles in the bag.
The probability of taking at random a red marble is equal to the quotient between the number of red marbles and the total number of marbles, this is:
p = 3/8
Suppose we got a red marble:
Now we replace the red marble we took, so in the bag there are again 3 red marbles and 8 total marbles, then the probability of getting another red marble is again:
q = 3/8
The joint probability (this is, the probability of both events happening) is equal to the product of the individual probabilities, with gives us:
P = p*q = (3/8)*(3/8) = 9/64 = 0.141

Answers
Answer:

Step-by-step explanation:
5x+5y = 10 and 2x+2y=4
0 = 0
3x-6y = 4 and - 4x+8y=7
0 = 37 / 3
6x+2y = 6 and 7x+3y=9
0 = 3
3x-4y = 16 and 2x+3y = 5
x=4 and y=−1

This problem is not very well defined. Notice the circle at the bottom left. It's less than 1/2 a circle. Question: do you count it or don't you. The answer to that question will influence other partial figures.
All you do is count the total number of figures and the number of triangles. I did count the part circle on the lower left as with the triangles that are missing their tops.

15x² - 3x - 7
Step-by-step explanation:
(12x² + 2x) - (-3x²+ 5x + 7)
First open the parentheses by applying the distributive property.
To do this, multiply each term you have inside (-3x⅔ + 5x + 7) by -1.
Thus, you would have the following:
12x² + 2x + 3x² - 5x - 7
Add like terms
12x² + 3x² + 2x - 5x - 7
15x² - 3x - 7

Heyya little student!
Sin means [tex]\frac{opposite }{hypotenuse}[/tex]
5 is the hypotenuse (its opposite to 90 degrees )
So, sin β would be:-
the side opposite to the angle β divided by the hypotenuse of the triangle.
The side opposite to β is 4
and as I said earlier, the hypotenuse is 5
So, sin β would be:-[tex]\frac{4}{5}[/tex]I hope it helped you!

The set for a school play needs a replica of a historic building painted on a backdrop that is 20 feet long and 16 feet high. The actual building measures 320 feet long by 256 feet high. A stage crewmember writes (x, y) arrow right ( 1/20 x, 1/20y) to represent the dilation. Is the crewmember's calculation correct if the painted replica is to cover the entire backdrop? Complete the explanation.
Answers
Answer:
Stage crewmember's calculation is incorrect
Correct = 1/16x 1/16y
Step-by-step explanation:
Given that:
Dimension of backdrop : 20 feets long ; 16 feets high
Actual dimension of building : 320 feets long ; 256 feets high
The correct scale factor can be obtained thus :
Ratio of backdrop dimension to the actual dimension of building
Length : 20 / 320 = 1 /16
Height : 16 / 256 = 1/16
Hence, stage crewmember's calculation of (1/20x ; 1/20y) is incorrect.

Step-by-step explanation:
I'm going to assume that I am solving for width.
Area = width x length
84 = 2/3 x width
Now divide 84 by 2/3 to get the width (when you divide by a fraction, you actually multiply by its reciprocal, so it is 84 times 3/2)
84 x 3/2 = width
width = 126 feet
