3(-2-4v)<-90 help I'm stuck on this one

1 answer:

5 0

Well, if you disregard the signs for a second, you can work this like a normal equation:
-6 - 12v = 90
-12v = 96
v = 8
Now just reincorporate the less than sign:
v < 8

Find the volume of the pyramid. round to the nearest hundredth

hichkok12 [17]

Answer:

A. 17.35 mm³

Step-by-step explanation:

Volume of a Pyramid

$V = \frac{1}{3}Bh$

V ... volume

B ... area of base

h ... height

The base of this pyramid is a square. Area of a square is side times side.

$B = 3.5 \times 3.5$

Let's substitute in the formula.

$V = \frac{1}{3}Bh\\\\V = \frac{1}{3}(3.5\times 3.5)(4.25)\\\\V = \frac{1}{3}(12.25)(4.25)\\\\V \approx 17.35417 \text{ mm}^3$

Now let's round to the nearest hundredth.

V = 17.35 mm³

Original price : $82 discount : 10% sales price : ? what does sales price equal ?

kozerog [31]

To find 10% of 82, you do 82*.1 so 8.2 is taken off the total.

So if we do 82-8.2 you get 73.8 as the sale price

Hope this helps

AA Similarity Postulate means Angle Angle Congruency which means that <A and <D are both 55° and <B and <E are both 60°

So, to solve for C, since a triangle has a total of 180° you subtract 180-55-60 to get C.

m<C = 65°

Hope this helped :)

For each customer, a bakery charges p dollars for the first loaf of bread bought by the customer and charges q dollars for each

Dominik [7]

Answer:

Consider the complete question is,

'For each customer, a bakery charges p dollars for the first loaf of bread bought by the customer and charges q dollars for each additional loaf bought by the customer. What is the value of p ?

(1) A customer who buys 2 loaves is charged 10 percent less per loaf than a customer who buys a single loaf.

(2) A customer who buys 6 loaves of bread is charged 10 dollars.

Solution :

Since, the charges of first loaf = p dollars,

Charges for each additional loaf = q dollars

Thus, the total charges for x additional loaf = p + qx

Charges for 1 loaf = p,

Charges for 2 loaf per loaf = (p + q)/2

According to the question,

$\frac{p + q}{2} = (100-10)\%\text{ of } p$

$\frac{p + q}{2} = 90%\text{ of }p$

$p + q = 1.8p$

$p + q - 1.8p = 0$

$-0.8p + q = 0$ .....................(1),

Again according to the question,

p + 5q = 10 .....................(2),

Equation (2) - 5 × equation (1),

p + 4p = 10

5p = 10

⇒ p = 2

Hence, the value of p would be 2.
