Answers

Answer:

B; 40

Step-by-step explanation:

We know that the triangle RST was dilated, meaning that the triangles are exactly the same in angles but not side lengths, which cancels out option C. We also know that the x and y values were multiplied by [tex]\frac{5}{6}[/tex]. Because of this, we must dilate the side length RS by 5/6. 5x48 is 240 and 240/6 is 40, giving us option B. Hope this helps!

8262 divided by 35 equals 236.05 something something something. So that is more than 236. Close, but no.

Answer:

Well the exact amount of gallons per day would be 236.057142857

But, if we are estimating then the gallons per day would be 236.

And if we are estimating then Yes Farrah did meet her goal.

But if we are not estimating then No Farrah did not meet her goal. Since 236.05... is bigger than 236.

What is Fraction?

Every fraction has a numerator and a denominator separated by a horizontal bar known as the fractional bar.

The denominator represents the number of components into which the whole has been subdivided. It is positioned below the fractional bar in the lower section of the fraction.The numerator specifies how many fractional parts are depicted or selected. It is positioned above the fractional bar in the upper section of the fraction.

Given:

Jm tosses a biased coin 50 times, and it lands on heads 40 times.

So, the fraction for getting tail out of 50 times

= (50- 40) / 50

= 10 / 50

= 0.2

Now, if the coins tossed 22 more times then number of tails are

= 22 x 0.2

= 4.4

So, the difference between the number of heads and tails

= 22 - 4.4

= 17.6

at a summer camp 23 of the boys and 17 of the girls can swim there nine boys 11 girls at the camp who cannot swim. what is the ratio or the number of children who can swim to the number of children who cannot swim.

Answers

Answer:

30 kids that can swim to 20 kids who cannot swim.

Step-by-step explanation:

There are 30 kids who can swim and 20 kids who can not swim.

So the ratio is 30  kids who can swim and 20 kids who can not swim.

The required ratio of the number of children who can swim to the number of children who cannot swim is 1:1.

Given that,
At a summer camp, 23 of the boys and 17 of the girls can swim there are nine boys 11 girls at the camp who cannot swim. what is the ratio or the number of children who can swim to the number of children who cannot swim is to be determined.

What is the Ratio?

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

here,
number of boy can swim  = 23 - 9 = 14
num,ber of girl can swim = 17 - 11 = 6
The total number of children who can swim = 20
The total number of children who cannot swim = 20
Ratio = 20: 20
Ratio = 1:1

Thus, the required ratio of the number of children who can swim to the number of children who cannot swim is 1:1.

Step-by-step explanation:

help me please. (Algebra I)

Answers

the answer is F. 164 tickets were sold for $8 each

------------------------------
Equations:
Quantity Eq.::: x + y = 480
Value Eq.::::: 5x +8y = 2895
------
Multiply thru the Quantity equation by 5
5x + 5y = 5*480
5x + 8y = 2895
---
Subtract the 1st from the 2nd:
3y = 495
y = 165 (# of non-student tickets sold)
---
Since x+y = 480, x = 480-165 = 315 (# of student tickets sold)
