Shelby's Ice Cream Shop sold 8 sundaes with nuts and 4 sundaes without nuts. What is the ratio of the number of sundaes with nut
Romashka-Z-Leto [24]

Answer: 2:1

Step-by-step explanation:

The ratio of A to B is given by :  \dfrac{A}{B} or A : B  .

Given : sundaes with nuts  = 4

sundaes without nuts = 8

The ratio of the number of sundaes with nuts to the number of sundaes without nuts = \dfrac{8}{4}=\dfrac{2}{1}\ \ \ [\text{Divide numerator and denominator by 4 }]

= 2:1

hence, the required ratio = 2:1 .

​ y=3x+3 y=−2x+3 ​ how many solutions does the system have
allochka39001 [22]

Answer: One solution

Step-by-step explanation:

y = 3x + 3

y = -2x + 3

-----------------------------------------------------------------------------------------------------------

To solve this, you need to understand a few things:

a) If two lines have the same slope but different y-intercepts, they are parallel when graphed and thus do not have any solutions

b) If two lines have the same slope and same y-intercepts, they are the same line when graphed and thus do not have infinitely many solutions

c) If two lines have different slopes (and/or y-intercepts), they have one solution

-----------------------------------------------------------------------------------------------------------

These two lines have different slopes but the same y-intercept (condition c)

So they have one solution

LUCKY_DIMON [66]

Answer:

268.0 in²

Step-by-step explanation:

refer to attached graphic as reference

volume of cone, V = (1/3) πr²h

in our case, we are given r = 4" and h = 16"

substituting this into equation:

V = (1/3) πr²h

=  (1/3) ·(3.14) · (4)²· (16)

= 267.94667 in²

= 268.0 in² (nearest tenth)
