Paula has a dog that weighs 3 times as much as Carla's dog. The total weight of the dogs is 80 pounds. How much does Paula's dog

Vedmedyk [2.9K]

Answer:

60 lb

Step-by-step explanation:

Represent the weights of the dogs by P and C. Then P = 3C.

Then P + C = 80, or, after substitution of 3C for P,

3C + C = 80, or

4C = 20, so that C = (20 pounds)

Paula's dog weighs 3 times as much as Carla's: P = 3(20 lb) = 60 lb

1) Factor the expression and use the fundamental identities to simplify. There is more than one correct form of the answer.

Art [367]

Answer:

Step-by-step explanation:

1) 6 tan2x − 6 tan2x sin2x

= $6tan2x(1-sin2x)\\= 6tan2x (sin^2 x + cos^2 x -2sinx cosx)\\= 6tan2x (sinx+cosx)^2\\$

2) $\frac{3}{1+cos x} +\frac{3}{1-cosx} \\=\frac{3-cosx+3+cosx}{1-cos^2 x} \\=\frac{6}{sin^2 x} \\=6 cosec^2 x$

3) $\frac{sin^2 y}{1-cosy } =\frac{1-cos^2 y}{1-cosy }\\=1+cosy$

4) x=6cos t

So cost =x/6

$sint = \frac{\sqrt{36-x^2} }{\{6 } \\$

so -3sint

Ben earns $10 per hour and $6 for each delivery he makes. He wants to earn more than $155 in an 8-hour workday. What is the leas

monitta

Answer:

the number of deliveries would be 13

And, the equation is d ≥ 12.50

Step-by-step explanation:

The inequality function is given below:

Let us assume the d be the number of deliveries

10 × 8 + 6 × d ≥ 155

80 + 6d ≥ 155

6d ≥ 155 - 80

6d ≥ 75

d ≥ 75 ÷ 6

d ≥ 12.50

hence, the number of deliveries would be 13

And, the equation is d ≥ 12.50
