A middle school took all of its 6th grade students on a field trip to see a play at a theater that has 2780 seats. The students left 15% of the seats in the theater vacant. How many 6th graders went on the trip?

Answers

Answer:

1242 6th graders went on the trip.

Step-by-step explanation:

From the information given, you know that the theater has 2760 seats and that the students filled 45% of the seats, so to find the quantity of 6th graders that went on the trip, you have to calculate 45% of 2760:

2760*45%=1242

According to this, the answer is that 1242 6th graders went on the trip.

Question 2 (1 point)
Carmillo estimates the weight of his dog. The veterinarian says that the dogs weights 84 pounds. If the actual weight is 78 pounds, is the
percent error in Camilo's estimte less than 10%?
True
False

Answers

Answer:

The estimated weight is in the range:

75.6 pounds  Weight  92.4 pounds

Step-by-step explanation:

Since, the maximum error is 10%.

Therefore, the maximum and minimum vales will be 10% more and 10% less than 84 pounds, respectively.

For Maximum Limit:

= (1.1)(84 pounds)

= 92.4 pounds

For Minimum Limit:

= (0.9)(84 pounds)

= 75.6 pounds

Hence, the estimated weight is in the range:

75.6 pounds  Weight  92.4 pounds

You can use process of elimination for this one. So first, obviously it wont be lower than the last test score which is at 65%, so you can mark off A and B. Then, if you notice the test scores fall right next to the big blue line, so find 9 hours, and then look all the way up to where it touches the line and you can see it is about a little less than 80%, which can mean that it obviously ain't D, so it is therefore C.

Noah and Lin are making paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 28.26 cubic inches of popcorn. If the height is 19 inches, what is the radius?

Answers

Answer:

1.2 in approx

Step-by-step explanation:

Given data

Volume of the cone= 28.26 in^3

Height= 19 in

Radius= ????

We know that the volume of the cone is expressed as

V= 1/3πr^2h

substitute

28.26= 1/3*3.142*r^2*19

28.26= 19.89*r^2

divide both sides by 19.89

r^2= 28.26/19.89

r^2= 1.42

r=√ 1.42

r= 1.19

Hence the radius is 1.2 in approx

Answers

Answer:

Below

Step-by-step explanation:

A parallelogram has 4 sides and is flat. Theyre sides are parallel to each other. While all the rhombus sides are equal in length, the parallelograms sides are equal in the opposite sides. The diagonals of a rhombus bisect each other at right angles forming two scalene triangles

9514 1404 393

Explanation:

A rhombus is a parallelogram, so in order to answer the question, we must restrict consideration to a parallelogram that is not a rhombus. We are not excluding the case(s) where the angles are right angles.

Similarities between rhombus and parallelogram:

diagonals bisect each otheradjacent angles are supplementaryopposite sides are parallel

Differences between rhombus and parallelogram:

diagonals of a parallelogram don't meet at right anglesdiagonals of a parallelogram are not angle bisectorsadjacent sides of a parallelogram are different length

Becca earns money mowing her neighbors lawns.

What is p(x)?

Answers

The function of p(x) is p(x) = 13x - 20

How to find function?

The revenue for mowing x lawn is r(x) = 18x

Her cost for gas and mower rental is c(x) = 5x + 20

Profit for mowing is p(x) = (r - c)(x)

p(x) = r(x) - c(x)

p(x) = 18x  - (5x + 20)

p(x) = 18x - 5x - 20

p(x) = 13x - 20
