the cost of a personal pizza is $4. a drink cost $1. Anna wrote the equation y=4x + 1 to represent the relationship between total cost y of buying x meals that include one personal pizza and one drink. Describe Anna's error and write the correct equation

Answers

Answer 1

Answer: the correct answer should be y=4x + 1d where x equals the number of personal pizzas, and d equals the number of drinks.

She didn't account for the number of drinks ordered for more than one meal.

Answer 2

Answer: Anna has to say y= 4x + 1z in order to get the answer. She didn't realize that she has to put a variable next to both.

Patrick ate 3/5 of a small pizza. For lunch Saturday he4 ate 1/2 of the leftover pizza. How much pizza did he eat for lunch on Saturday?

Answers

Whole one pizza = 1 = 5/5
Patrick ate on Friday 3/5 so 5/5-3/5=2/5
On Saturday P. ate 1/2 of 2/5 so = 1/2*2/5= 2/10=1/5
So deduct 1/5 from 2/5 and we have 1/5 left

Final answer:

Patrick ate 1/5 of the pizza for lunch on Saturday. To find this, we first calculated how much pizza was left over after he initially ate 3/5 of it, which was 2/5. Then, knowing he ate half of the leftover pizza, we multiplied 2/5 by 1/2 to get 1/5.

Explanation:

The subject of this question is fractions. In this problem, we want to find out how much of the leftover pizza Patrick had for lunch on Saturday. Initially, Patrick ate 3/5 of the pizza, which means 2/5 of the pizza was left over. Then, he ate 1/2 of that remaining pizza for lunch on Saturday.

To find how much pizza he actually ate, we need to multiply the fractions. That is, 2/5 (leftover pizza) * 1/2 (Patrick's lunch). When you multiply these two fractions, you get 2/10 or 1/5. Therefore, Patrick ate 1/5 of the pizza for lunch on Saturday.

Solve the equation
5(-4a+8)-5(6a-5)=15

Answers

Step 1: Simplify both sides of the equation.

5(−4a+8)−5(6a−5)=15

(5)(−4a)+(5)(8)+(−5)(6a)+(−5)(−5)=15

−20a+40+−30a+25=15

(−20a+−30a)+(40+25)=15

−50a+65=15

Step 2: Subtract 65 from both sides.

−50a+65−65=15−65

−50a=−50

Step 3: Divide both sides by -50.

-50a/-50=-50/-50

Therefore, the answer would be a=1.

We can factor 5 at the left hand side:

$5[(-4a+8)-(6a-5)]=15$

Divide both sides by 5:

$(-4a+8)-(6a-5)=3 \iff -4a+8-6a+5 = 3$

Sum like terms:

$-10a+13=3$

Subtract 13 from both sides:

$-10a=-10$

Divide both sides by -10:

$a=1$

how do u calculate the distance from the centre of the circle to the centre of one edge of the hexagon

Answers

check the picture below.

bearing in mind that a circle has a total of 360°, and a radius line coming from the center of the hexagon, will make an angle of 360°/6 or 60° for each side with the center of the circle, as you see in the picture.

if we run a bisector line through one of those 6 angles, we end up splitting it in two equal halves, namely two 30°, so that the apothem and the radius both coming from the center, with the side, make a 30-60-90 triangle, as you see there.

Can somebody help me with this?

Answers

Answer:

E) 1/2

Step-by-step explanation:

This is no ordinary problem. It actually requires you to solve two different problems in order to figure out the correct answer.

First, we must figure out what the hypotenuse of the triangle is. We have the two small sides (5 and 12), but don't have the larger side. To find this, we must use the Pythagorean theorem: $a^(2) + b^2 =c^2$
