Answer:

4V = 3U

Step-by-step explanation:

The final cost of a sale item is determined by multiplying the price on the tag by 75%.

Let us assume that the final cost of the sale item is V and the price on the tag is given by U.

Then the equation that best describes the function that represents the situation is V = \frac{75U}{100} =\frac{3U}{4}

⇒ 4V = 3U  (Answer)

Circumference of the circle with the given radius 3 1/2 cm<br>a.7.5<br>b.7<br>c.6.25​
Sonja [21]

Let's do these in steps. Remember to show your work

#1. Convert into a improper fraction.

3 x 2 x 1 over 2cm.

#2. Simplify 3 x 2 to 6.

6 + 1 over 2cm.

#3. Change 6+1 to 7.

7 over 2m.

We finally get 7 over 2, but that rounded would be 7. So B would be our answer.

A pizza shop delivered 17 pepperoni pizzas to a college on the first night of final exams. The total cost of the pizzas was &amp
Allushta [10]

Answer:

Step-by-step explanation:

Let x = number of small pizzas

Let y = number of medium pizzas

Let z = number of large pizzas

Total weight of pizza = 9 *16 +8 = 152

Total pizza  = 17

Total amount = $153

x + y + z = 17                     - equation 1

4x + 6y + 15z = 153          - equation 2

3x + 9y + 14z =  152             - equation 3

from equation 1,  x = 17 -y -z - equation *

substitute in both 2 and 3

4(17 -y -z) + 6y + 15z = 153   ---- 1

3(17 -y -z) +9y +14z  = 152   --- 2

68 - 4y - 4z +6y + 15z = 153 ----i

51 - 3y - 3z + 9y + 14z = 152 ---ii

2y + 11z  = 85  ---1

6y +11z = 101  ----2

equation 2 minus equation 1

4y = 16 => y = 4

substitute y in equation 1

8 + 11z = 85 => 11z = 77 => z = 7

subtitute y as 4 and z as 7 in equation *

x = 17 - 4 -7  => x = 6

So, 6 small pizzas, 4 medium and 7 big pizzas were delivered

Answer:

0.0466

Step-by-step explanation:

For a random variable X which follows a binomial distribution:

n = 7\\p = 0.35

Thus,

P(X=5)={7\choose5}(0.35)^5(1-0.35)^{7-5}\\P(X=5)={7\choose5}(0.35)^5(0.65)^{2}\\P(X=5)=0.0466
