[tex]6\:\text{cups}[/tex]

Step-by-step explanation:

Since the proportion is maintained, we can set up the following proportion:

[tex]\frac{2/3}{1}=\frac{x}{9}[/tex], where [tex]x[/tex] is the amount of glitter, in cups, Mindy will use to make 9 cups of glittery paint.

Cross-multiply to get:

[tex]1x=9\cdot \frac{2}{3},\\x=9\cdot \frac{2}{3}=\boxed{6\:\text{cups}}[/tex]

Answer:

x      -1       0       1       2       3

y      2       4       6      8       10

Step-by-step explanation:

y = 2x + 4

x = -1: y = 2(-1) + 4 = 2

x = 0: y = 2(0) + 4 = 4

x = 1: y = 2(1) + 4 = 6

x = 2: y = 2(2) + 4 = 8

x = 3: y = 2(3) + 4 = 10

x      -1       0       1       2       3

y      2       4       6      8       10

Answer:

a = 7, b = [tex]\frac{7\sqrt{3} }{3}[/tex]

Step-by-step explanation:

Using the sine ratio in the left right triangle and the exact value

sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{a}{7\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

a × [tex]\sqrt{2}[/tex] = 7[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )

a = 7

--------------------------------------------------------

Using the tangent ratio in the right triangle on the right and the exact value

tan60° = [tex]\sqrt{3}[/tex] , then

tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{a}{b}[/tex] = [tex]\frac{7}{b}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by b )

b × [tex]\sqrt{3}[/tex] = 7 ( divide both sides by [tex]\sqrt{3}[/tex] )

b = [tex]\frac{7}{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex] = [tex]\frac{7\sqrt{3} }{3}[/tex]

We can use a scientific calculator or look up the sine of 25 degrees in a table of trigonometric values. The answer would be approximately 2.13 cm.

A right angle triangle is a triangle in which one of the angles is equal to 90 degrees. In other words, it is a triangle in which one angle is a "right angle." Right angle triangles are commonly used in geometry and trigonometry, and they play a crucial role in many real-world applications, such as surveying, construction, and navigation.

In a right triangle, the length of one side can be found using the sine function. The sine of an angle in a right triangle is defined as the ratio of the length of the opposite side to the length of the hypotenuse. In this case, the angle MNO is 25 degrees, so we can write the following equation to find the length of side MN:

MN = NO * sin(25°) = 4 cm * sin(25°)

To find the numerical value of MN, we can use a scientific calculator or look up the sine of 25 degrees in a table of trigonometric values. The answer would be approximately 2.13 cm.

Answer:C and D

Step-by-step explanation:

Answer:

ok so the answer would be h

Step-by-step explanation:

so basically the ratio is 4:2 -1:2 so purple is 2 and orange is 4. meaning purple is half of the orange. that ratio stays the same. if you were to multiply puplr by 60 you get 120. and if you multiply 4 by 60 you get 240. which 240 divided by 120 is 2 meaning h is the right answer choice.

The correct observation is Spinner 1 would land on orange the same number of times that Spinner 2 would land on purple.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

Total times spined = 60

Spinner 1 land on orange out 60 times

= 4/20 x 60

= 1/5 x 60

= 12

Spinner 2 land on Purple out 60 times

= 2/10 x 60

= 1/5 x 60

= 12

Hence, Spinner 1 would land on orange the same number of times that Spinner 2 would land on purple.

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the side "?" is the Adjacent side (Adj)  and we are given the angle and the Hypontenuse ( long side) (Hyp)  of this triangle

so use CAH

cos(75) =  Adj / 8

algebra to solve for the Adj side (which is the "?" for this problem )

8*cos(75) = Adj

2.07055 = Adj

so the "?" is  2.1 ft ( rounded to the nearest 10th )

Answer:

V = 340.339

Step-by-step explanation:

V = [tex]\frac{\pi r^{2} h }{3}[/tex]

V = [tex]\pi[/tex][tex](5)^{2}[/tex] [tex]\frac{13}{3}[/tex] = 25[tex]\pi[/tex] [tex]\frac{13}{3}[/tex]  = about 340.3392 = 340.339

Answer:

340.17 ft.

Step-by-step explanation:

Using the formula, πr²h ÷ 3 (3.14 × radius × radius × height ÷ 3), we can plug-in the unknown values.

'r' means radius; 'h' means height; 'π' means pi.

The radius is 5; the height is 13.

πr²h (3.14 × radius × radius × height ÷ 3) - π5² × 13 = 340.166666667 (3.14 × 5 × 5 × 13 ÷ 3 = 340.166666667)

340.166666667 ≈ 340.17

Therefore, the area of this circular cone is 340.17 ft.
