Cara's grocery bill this week was $7.60 more

Mathematics

Doss [256]2 years ago

Cara's bill was $30.51 this week.

Cara's bill was $7.60 more than two-thirds of her grocery bill last week.

First thing we need to do therefore, is to find out what 2/3 of her bill was last week:

= 2/3 x 34.37

= $22.91

Her bill was $7.60 more than this amount so it was:

= 7.60 + 22.91

= $30.51

Cara's bill was therefore $30.51 this week.

Because the triangles are similar the ratio of all the sides would be the same. So you need to find the ratio of the common sides and then use that ratio to find the unkown side.

In this picture sides FG = 52, FV would be the same side and is 24.

Dividing 24/52 = 0.461, so the unkown side WV would be 0.444 of it's common side HG.

HG = 39

39 * 0.461= 18.

The answer is C. 18

You buy x bottles of soda for $1.50 using a gift card that you got as a reward for getting good grades
nadya68 [22]

Answer:

0\leq x \leq 10

Step-by-step explanation:

The function is  f(x)=15-1.50x  where x is the number of bottles of soda.

The domain means the set of "allowed" x values.

Also, f(x) means the amount of money left, which cannot be less than 0. So we put 0 into f(x) and solve for x:

f(x)=15-1.5x\\0=15-1.5x\\1.5x=15\\x=\frac{15}{1.50}\\x=10

This means the highest number of bottles you can buy is 10. So the domain is anything from 0 to 10. <em>You can buy 0 until highest 10 bottles. Hence the domain is </em>

0\leq x \leq 10

The least value of the function x^2 + px + q is 3 and this occurs when x = - 2. find the values of p and q
Rasek [7]

Answer:

Hello,

p=4

q=7

Step-by-step explanation:

The vertex of the parabola is (-2,3)

Equation of the parabola is  k(x+2)²+3=x²+px+q

Let's identify the coefficients:

kx²+4kx+4k+3=x²+px+q

so

k=1

4*1=p

4*1+3=q
