Answer quick and i’ll mark branliest. Tomas makes balloon sculptures at a circus. In 96 minutes, he uses 160 balloons to make 32
MissTica

Answer:

3 min.

5 balloons.

Step-by-step explanation:

How many minutes does it take to make one balloon sculpture?

t = (Total time) /  (Total identical  balloon sculptures) = 96 / 32 = 3 min.

How many balloons are used in one  sculpture?

n = (Total balloons) /  (Total identical  balloon sculptures) = 160 / 32 = 5 balloons.

A kangaroo hooped 3,520 yards to the lake with her baby in her pouch. She hopped the remaining 5,280 yard without her baby in he
Akimi4 [234]

Answer:

5 miles

Step-by-step explanation:

since she hopped in yards you must mulitiply both numbers 3520 and 5280 by 3 since there are three feet in a yard. then add together then divide the sum by 5280 since a mile is 5280 feet.

3520 X 3 = 10560

5280 X 3 = 15840

10560 + 15840 = 26400

26400/ 5280 = 5

The power generated by an electrical circuit (in watts) as a function of its current ccc (in amperes) is modeled by: P(c)=-12c^2
g100num [7]

Answer:

5 amperes will produce the maximum power of 300 watts.

Step-by-step explanation:

The general form of a quadratic function presents the function in the form

f(x)=ax^2+bx+c

The vertex of a quadratic function is the highest or lowest point, also known as the maximum or minimum of a quadratic function.

We can define the vertex by doing the following:

  • Identify a, b, and c
  • Find, the x-coordinate of the vertex, by substituting a and b into

x-coordinate =-\frac{b}{2a}

  • Find, the y-coordinate of the vertex, by evaluating

y-coordinate =f(x-coordinate )=f(-\frac{b}{2a} )

We know that the power generated by an electrical circuit is modeled by

P(c)=-12c^{2}+120c

This function is a quadratic function.

To find the current that produce the maximum power you must

  • Identify a and b

a = -12 and b = 120

  • Find, the maximum current of the vertex, by substituting a and b into

maximum-current =-\frac{b}{2a}

maximum-current =-\frac{120}{2(-12)}\\\\maximum-current = 5

  • Find, the maximum-power, by evaluating

maximum-power =P(maximum-current)=P(-\frac{b}{2a} )

P(5)=-12(5)^{2}+120(5)=300

5 amperes will produce the maximum power of 300 watts.

We can check our work with the graph of the function P(c)=-12c^{2}+120c and see that the maximum is (5, 300).

3) When solving a one-step equation, we apply the inverse operation to the value on the _____ of the variable.
sesenic [268]

Answer:

To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself. The inverse operations are: Addition and subtraction. Multiplication and division.

Step-by-step explanation:

by it self.

If the spinner is spun, what is the probability that the spinner will land on a multiple of 4
vesna_86 [32]
In the usual spinner that we have, the circular figure is divided into 8 equal parts. Each of which is numbered from 1 to 8. There are two of these numbers that are multiple of 4 (4 and 8). Now, the probability that the spinner will land on a multiple of 4 is equal to 2/8 or also equal to 1/4 or 0.25.
