Answer:

You will have 48 blue streamers.

Step-by-step explanation:

This question can be solved by proportions, using rule of three.

We have that:

For 12 blue streamers, there are have 9 gold streamers. How many blue streamers are there when there are 36 gold streamers?

12 blue - 9 gold

x blue - 36 gold

Applying cross multiplication

$9x = 36*12$

Simplifying by 9

$x = 4*12 = 48$

You will have 48 blue streamers.

Lostsunrise [7]

Dominics son is 45inches tall

Step-by-step explanation:

Let his sons height be 'h'

If Dominic is 72 inches and casts a shadow of 60 inches. His son casts a shadow of 50 inches.

Then We can say that,

h = 50 x (72/60)

h = 45 inches

Dominics son is 45inches tall

PLEASE HELP ME IN THESE TWO QUESTIONS ASAP! AND YES, I AM GOING TO MARK YOU AS THE BRAINLIEST ANSWER!!!!!

The line from the point to its reflection should be perpendicular.If we imagine a line from (5,7) to (2,2), it would have a slope of (2-7)/(2-5) = 5/3.

For that line to be perpendicular to y=-2/5x+6, their slopes should be each other's negative reciprocals.

-2/5 negative reciprocal is 5/2, which is not equal to our calculated 5/3, so (2,2) cannot be the reflected point. Evan was wrong.

Q1-74: AB have slope 6/5, C has -5/6, D 6/5, E -5/6 again.

What is y=7/3x+5? x=-3

andrew11 [14]

Hello!

Ok so we have y= 7/3x + 5 and initial condition of x=-3 so we just plug -3 in for x and chug along at this point! :)

y=(7/3)*(-3/1)+5= -7+5 = -2

Hope this helps! Any questions please just ask! Thank you!!

Find a set of 5 positive integers that has a possible mode of 5, a median of 7 and a mean of 9

Pavel [41]

Answer:

You could have a set of [5, 7, 13, 15, 5]

Step-by-step explanation:

The mode is 5 (5 occurs the most in the set).

Definition of the mode of a set:

The mode of a set of data is the value in the set that occurs most often. In the problem above, 18 is the mode. It is easy to remember the definition of a mode since it has the word most in it. Fun fact: The words mode and most both start with the letters mo.

The median is 7 (if you put the numbers in strictly increasing order, 7 will be the middle number).

Definition of the median of a set:

The median of a set of data is the middlemost number or center value in the set. The median is also the number that is halfway into the set. To find the median, the data should be arranged, first, in order of least to greatest or greatest to the least value.

The mean is 9 (5 + 7 + 13 + 15 + 5).

Definition of the mean of a set:

The mean is the mathematical average of a set of two or more numbers. The arithmetic mean and the geometric mean are two types of mean that can be calculated. Summing the numbers in a set and dividing by the total number gives you the arithmetic mean.

Hope this helps.
