Answer:

tip = lunch * 10 percent

tip = 60* .10 = 6

total cost= lunch + tip

total cost =60+6 = 66

to share the cost equally, divide by 2

66/2 = 33

Use the diagram shown to find x.

marusya05 [52]

X would equal 70°.

For every triangle, all interior angles add up to 180°. This means that we can add together 42 and 68 to get 110°. Because the sum of all interior angles in a triangle must be 180°, we subtract 110 from 180 to see how much more we need, which gets us 70°.

I hope this helps!

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 7% vinegar, and the second brand co

Lina20 [59]

Answer: There is 162 ml of first brand and 108 ml of second brand.

Step-by-step explanation:

Since we have given that

Percentage of vinegar that the first brand contains = 7%

Percentage of vinegar that the second brand contains = 12%

Percentage of vinegar in mixture = 9%

Total amount of dressing = 270 ml

We will use "Mixture and Allegation":

First brand Second brand

7% 12%

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

12%-9% : 9%-7%

3% : 2%

So, ratio of first brand to second brand in a mixture is 3:2.

So, Amount of first brand she should use is given by

$\dfrac{3}{5}\times 270\\\\=162\ ml$

Amount of second brand she should use is given by

$\dfrac{2}{5}\times 270\\\\=108\ ml$

Hence, there is 162 ml of first brand and 108 ml of second brand.

Hi,

During halftime of a soccer game, a slingshot launches T-shirts at the crowd. A T-shirt is launched from a height of 5 feet with an initial upward velocity of 72 ft. Per second. The T-shirt is caught 34 feet above the field. How long will it take the T-shirt to reach its maximum height? What is the maximum height? What is the range of the function that models the height of the T-shirt over time.

Write the general equation that represents height of the t-shirt as a function of time.

f(t) = -16 $t^{2}$ + 72t + 5
