Keith wants to make cupcakes. To make cupcakes he needs 1 3/10 cups of flour per batch of cupcakes. If Keith has 13 cups of flou
marin [14]

Answer: Keith can make 10 batches of cupcakes.

Step-by-step explanation:

To make cupcakes, he needs 1 3/10 cups of flour per batch of cupcakes. Converting 1 3/10 cups of flour into improper fraction, it becomes 13/10 cups of flour.

Let x represent the number of batches of cupcakes that Keith can make If Keith has 13 cups of flour, . Therefore,

13/10 cups of flour = 1 batch of cupcakes

13 cups of flour = x batch of cupcakes

Cross multiplying, it becomes

13/10 × x = 13 × 1

13x/10 = 13

13x = 13 × 10 = 130

x = 130/13 = 10

Through: (3,5), slope=5\3
ANEK [815]
So slope intercpet form
y=mx+b

m=slope
b=y intercpet


slope=5/3
in (x,y) form

x=3
y=5 is one point


subsitute and solve for b
y=mx+b
5=5/3 times 3+b
5=3/3 times 5+b
5=1 times 5+b
5=5+b
subtract 5 from both sides
0=b

equation is
y=5/3x+0 or
y=5/3x

Rui is a professional deep water free diver.
Arada [10]

Answer:

Rui will reach his lowest altitude after diving for 10 seconds

Step-by-step explanation:

In the quadratic equation y = ax² + bx + c, the coordinates of the lowest or the highest point is (h, k), where

  • h = \frac{-b}{2a} and k = y at x = h

In the given question

∵ d(x) = \frac{1}{2} x² - 10 x

∵ d represents his altitude in meters after x seconds

→ Compare it with the form above to find a and b

∴ a =  \frac{1}{2} and b = -10

∵ h = \frac{-b}{2a}

→ Substitute the values of a and b in the rule to find h

∴ h = \frac{--10}{2.\frac{1}{2}} = 10

∴ h = 10

∵ h is the x-coordinate of the lowest point

∴ The time of the lowest altitude is 10 seconds

∴ Rui will reach his lowest altitude after diving for 10 seconds
