The surface area of a square pyramid is 136 square inches. The base length is 4 inches. What is the slant height? please help!

Answers

Answer 1

Answer:

the surface area is 136

you need to subtract the surface area of the base. It is a square pyramid, so both the sides are 4 inches, meaning you need to multiply 4x4 which is 16 and subtract it from the rest of the area. 136-16=120

There are four identical triangles that have identical surface area because it is a square triangle. So you can divide 120 by four to get the area of one of the triangles. 120/4=30

the formula for the area of a triangle is 1/2 base x height. We know that the base is 4 because that is the length that was given to us. so we can plug in our numbers into the formula

30=1/2(4)(height)

30=2(height)

and from there we can solve. 30/2=15

the height of the triangle is 15, which is also the slant height

to check our work, 1/2(4)(15)=30

4x15=60

1/2x60=30

Nene buys a new bowling ball that weighs 10 pounds 13 ounces at the store what is the total weight of the bowling ball in ounces

Answers

Given:
Bowling ball weight: 10 pounds 13 ounces

Total weight in ounces.

1 pound is equal to 16 ounces

10 pounds * 16ounces/1pound = 10 * 16oz = 160 ounces

160 ounces + 13 ounces = 173 ounces

The bowling ball weighs a total of 173 ounces.

Since a pound has 16 ounces in it, we do 16 times 10 and that is 160 plus 13. The answer is 173 ounces.

Sarah cut off 1/8 of 48 inch piece of ribbon. Jane cut off 1/9 of a 36 inch piece of ribbon. They compare their cut piece. Whose piece is longer? How much longer

Answers

1/8 of 48 is 6, so Sarah cut 6 inches. 1/9 of 36 is 4, so Jane cut 4 inches. 6 is greater than 4, therefore, Sarah's piece is longer by 2 inches.

Erik took a trip to see his friend Mike who lives 308 miles away. He left his place at 10 AM driving at 70 mph. In 2 hours, his friend Mike left his place driving towards Erik at an average speed of 50 mph. At what time will they meet?

Answers

Answer:

Erik and Mike will meet at 1:24 PM

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Distance between Erik and Mike = 308 miles

Speed that Erik drove = 70 mph

Time Erik left = 10 AM

Speed that Mike drove = 50 mph

Time Mike left = 12 PM

2. At what time will they meet?

For answering the question, let's find how much miles Erik drove at 12 PM, when Mike started to drive towards Erik:

Miles driven by Erik after two hours = Speed * Time

Miles driven by Erik after two hours = 70 * 2

Miles driven by Erik after two hours = 140

Now we can calculate the distance between Erik and Mike at 12 PM, this way:

308 - 140 = 168

At 12 PM the distance between Erik and Mike is 168 miles

t = time it takes Erik and Mike to meet

The equation to solve for t is:

Distance Erik will travel = 70t

Distance Mike will travel = 50t

70t + 50t = 168

120t = 168

t = 168/120

t = 1.4 hours

1.4 hours = 1 hour + 4/10 * 60 minutes = 1 hour + 24 minutes

Time of the day Erik and Mike will meet = 12 PM + 1 hour and 24 minutes

Time of the day Erik and Mike will meet = 1:24 PM

Answer:

1:24 pm

Next week your math teacher is giving a chapter test. The test will consist of 35 questions. some problems r worth 2 point and some r worth 4 points. there are 20 questions worth 2 points. how many problems are worth 4 points. solve by substitution

Answers

20 questions are worth 2 points and 15 questions are worth 4 points.

Let x represent the number of problems worth 2 points and y represent the number of problems worth 4 points.

The test will consist of 35 questions. Hence:

x + y = 35 (1)

There are 20 questions worth 2 points, hence x = 20:

x + y = 35

20 + y = 35

y = 15

Therefore 20 questions are worth 2 points and 15 questions are worth 4 points.

There are 35 total questions. You already know that 20 of the questions are worth 2 points. You subtract 20 from 35. 35-20=15. So 15 questions are worth 4 points.
Total questions~35. Worth 2 points~20. Worth 4 points~15.

A rectangular blanket's perimeter is 210 inches. If the long sides of the blanket measure 60 inches, what is the length of the shorter sides of the blanket?

Answers

perimeter is going to be figured by using 2L + 2W

2(60) +2W = 210
120 +2W = 210
-120 -120

2W = 90
divde by 2 on both sides

W = 45

Length of the shorter sides are 45 inches.

The lengh of the shorter sides is 45 inches
