A=4(3.14)4²
A=(12.56) (16)
A=200.96

Given two sides with lengths 34 and 14, which of these lengths would NOT work for the third side of a triangle? 18, 34, 44, 22, 40

Answers

Two sides are 34 and 14.

The third side can't be longer than (34 + 14) = 48, because the 34 and the 14
together could not reach from one end of it to the other.

The third side also can't be shorter than 20, because the 20 and the 14 together
could not reach from one end of the 34 to the other.

So 18 doesn't work. (18 + 14) = 32 ... they couldn't cover the 34 .

Lorenzo and Nicole survey students about their favorite subject. Lorenzo surveys 24 students. This is 4 times as many as the 6 students that Nicole suverys. Write an equation that represents this situation

Answers

Answer:

y = 4 * x

y is the number of students that Lorenzo surveys,

x is the number of students that Nicole surveys.

Step-by-step explanation:

Lorenzo surveys 24 students, so we can use this value as the left side of our equation.

The number of students that Lorenzo surveys is 4 times as many as the number of students that Nicole surveys, that is 6. So, we use the value of 6 in the right side of the equation, and multiplied by 4 (the expression "4 times as many as" means that one value is the second one multiplied by 4)

The expression that represents this is:

24 = 4 * 6

If we use the variable y to express the number of students that Lorenzo surveys and x to express the number of students that Nicole surveys, we can write this equation:

y = 4 * x

Answer: 16

Step-by-step explanation: A more simple approach is realizing that the blocks show 8 x tiles and 1 x^2 tile. The 8 x tiles are on either side of the x^2 tile which is 4 x tiles on each side. So as we can see we can multiply each side together. 4x4 = 16. So that is how you get 16 without having to work it out.

only chocolate and vanilla ice cream cones are sold at an ice cream store. In one day, the number of chocolate cones sold was 1 more than 4 times the number of vanilla cones sold. A total of 121 cones sold that day

Answers

I just had this question for homework too!

c = 4v + 1
v + c = 121

Now use substitution.

v + 4v + 1 = 121
5v + 1 = 121
5v = 120
v = 24

The answer is 24.

Here's the equation:
4x+1+x = 121. Where x is equal to the amount of vanilla cones.
5x + 1 = 121
5x = 120
x = 24
There were 24 vanilla and 97 chocolate.
