Answer 1

Answer:

Step-by-step explanation:

cone: attached picture below

composite shape: To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together. You may have to calculate missing lengths before finding the area of some of the shapes.

ratio: not sure about that question sorry

last question: i have no idea what it is about because my device won't open the picture sorry

though i have answered 2 question of yours

have a great evening

Answer 2

Answer:

Cone

Surface area:

A = πr(r + l) r = √(10² - 8²) = √36 = 6A = 3.14(6)(6 + 10) = 301.44#1A = 25π, C = ?A = πr² ⇒ 25π = πr² ⇒ r² = 25 ⇒ r = 5C = 2πr = 2*3.14*5 = 31.4#2A = 5*7 + (5 - 2)*4 + 1/2*4*(6 - (5 - 2)) = 35 + 12 + 6 = 53#10

Scale factor

k = 3/4

Area is a function of two dimensions, each has k applied

The ratio of areas is the k² = (3/4)² = 9/16

Option C

Volume of prism:

V = Bh = 1/2(8*5)*6 = 120

Volume of pyramid:

V = 1/3Bh = 1/3(8*5)*9 = 120

Option A, same volume

Ratio of areas:

20/45 = 4/9

Scale factor is:

k² = 4/9k = √4/9k = 2/3

Complete the equation of the line through (-6, 5) and (-3, -3)

Answers

Answer:

y = -8/3x - 11

Step-by-step explanation:

(-6, 5) and (-3, -3)

Slope:

m=(y2-y1)/(x2-x1)

m=(-3-5)/(-3+6)

m=(-8)/3

m= -8/3

Slope-intercept:

y - y1 = m(x - x1)

y - 5 = -8/3(x + 6)

y - 5 = -8/3x - 16

y = -8/3x - 11

Harpo, Groucho, Chico, Zeppo, Gummo, Karl, and Skid have won three tickets to the opera. They will randomly choose three people from their group to attend the opera. How many outcomes are possible?

Answers

Answer:

Step-by-step explanation:

This is a combination problem therefore we need to use the combination formula using factorials, plug in the values for n and r which would be 7 since there are 7 individuals in the group and 3 because we are making outcomes of 3.

C(n,r)=C(7,3)

=7!(3!(7−3)!)

=7!3!×4!

= 35

Finally, we can see that the total number of possible outcomes is 35

Bailey made risotto using a recipe that called for 223 cups of liquid. Bailey added 23 cup of liquid to the risotto every 10 minutes. Drag and drop to complete the equation to find how many times Bailey added 23 cup of liquid.

Answers

Answer:

4 times

Step-by-step explanation:

Given that :

Cups of liquid required = 2 2/3

Fraction of liquid cup added per 10 minutes = 2/3

The number of times 2/3 cups of liquid is added :

Total cups of liquid required / amount of liquid added at a time

2 2/3 ÷ 2/3

8/3 ÷ 2/3

8/3 * 3/2

24 / 6

= 4 times

Find the angle between the given vectors to the nearest tenth of a degree.

u = <-5, 8>, v = <-4, 8>

2.7°
-7.3°
5.4°
15.4°

Answers

9514 1404 393

Answer:

Step-by-step explanation:

We can simply determine the difference between the angles of the vectors:

arctan(8/-5) -arctan(8/-4) = 122.005° -116.565° = 5.440°

The angle between the vectors is about 5.4°.

Alternate solutions

1) We could also determine the angle of their ratio.

u/v = (-5 +8i)/(-4 +8i) = (-5 +8i)(-4 -8i)/(4² +8²) = (84 +8i)/80 = 1.05 +0.1i

angle = arctan(0.1/1.05) = 5.440°

2) Tan(a-b) = (tan(a)+tan(b))/(1 -tan(a)(tan(b))

tan(∠u -∠v) = ((tan(∠u) -tan(∠v))/(1 +tan(∠u)tan(∠v))

= (-1.6 -(-2))/(1 +(-1.6)(-2)) = 0.4/4.2

∠u -∠v = arctan(2/21) = 5.440°

Every time Vince orders Chinese food, he gets egg drop soup. So, he decides to learn how to make it himself. His recipe calls for 1.5 liters of broth, but he can only find 500-milliliter cartons at the store. How many cartons should he buy?

Answers

Answer: 3

Step-by-step explanation:

Vince will have to buy three cartons of 500 ml each.

What is expression in mathematics?

An expression in mathematics is a combination of terms both constants and variables.

Given is that every time Vince orders Chinese food, he gets egg drop soup. So, he decides to learn how to make it himself. His recipe calls for 1.5 liters of broth, but he can only find 500 milliliter cartons at the store.

We know that -

1 Liter = 1000 milliliters

1.5 liter = 1500 liters

Now -

1 carton 500 ml.

Then, 1 ml will be in (1/500) carton.

So, 1500 ml will be in (1/500 x 1500) = 3 cartons

Therefore, Vince will have to buy three cartons of 500 ml each.
