Answer:

40%.

Step-by-step explanation:

Prob( Rolling a 4) = 12/50

Prob( Rolling a 3) = 8/50

When the combined probabilities contain  an 'OR' we Add the probability values:

Probability of a 3 or a 4  

= 12/50 + 8/50

= 20/50

= 2/5

= 40%.

The correct answer is C, 40%.

Answer:

18 gallons containing 20% solvent and 6 gallons containing 60% solvent

Step-by-step explanation:

the painter needs 24 gallons of paint containing 30% solvent = 7.2 gallons of solvent

let a = 20% solvent paint

let b = 60% solvent paint

a + b = 24

0.2a + 0.6b = 7.2

(replace a = 24 - b in the second equation)

a + b = 24

0.2(24 - b) + 0.6b = 7.2

4.8 - 0.2b + 0.6b = 7.2

0.4b = 7.2 - 4.8 = 2.4

b = 2.4 / 0.4 = 6

a = 24 - 6 = 18

Step-by-step explanation:

Answer:

x=9

Step-by-step explanation:

5x+12=3+6x

Subtract 5x on both sides to get the variable on the same side of the equation

12=3+x

Subtract 3 on both sides to isolate the variable

9=x

Answer:

x=9

Step-by-step explanation:

5x+12=3+6x

We can subtract 5x from both sides of the equation.

5x+12=3+6x

-5x          -5x

We get 12=3+x

We can subtract 3 from both sides.

12=3+x

-3  -3

We get 9=x or x=9.

x=9

Answer:

The center is at (3,1) and the radius is [tex]\sqrt{8}[/tex]

Step-by-step explanation:

I am going to assume you meant to write

[tex](x-3)^2+(y-1)^2 = 8[/tex]

Since if both variables were x it would not be a circle:

Then you can find the center and radius using the general formula of a circle:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

where the center is at (h,k) and r is the radius

Therefore:

The center is at (3,1) and the radius is [tex]\sqrt{8}[/tex]

Answer:

B, C.

Step-by-step explanation:

B, because you're multiplying them all, which is what you would do in the normal formula. You would get 255/16, or 15.9375.

C, since you would also get 255/16.

Answer:

75 cm

Step-by-step explanation:

It is given that the triangles are similar. It means that the ratio of their areas are equal to the ratio of their bases and ratio of their altitudes.

Let [tex]A_1[/tex] be the area of 1st triangle.

Let [tex]A_2[/tex] be the area of 2nd triangle.

Let [tex]h_1[/tex] be the altitude of 1st triangle.

Let [tex]h_2[/tex] be the altitude of 2nd triangle.

Let [tex]b_1[/tex] be the base of 1st triangle.

Let [tex]b_2[/tex] be the base of 2nd triangle.

Then [tex]A_1: A_2 = h_1 : h_2 = b_1 : b_2 ...... (1)[/tex]

[tex]A_1 = 42 cm^{2} \\A_2 = 262.5 cm^{2}\\h_1 = 7 cm\\b_2 = ?[/tex]

We know that area of a triangle is:

[tex]A = \dfrac{1}{2} \times b \times h[/tex]

Area of smaller triangle:

[tex]\frac{1}{2} \times b_1 \times 7 = 42\\\Rightarrow b_1 = 12 cm[/tex]

Now, using part of equation (1):

[tex]A_1: A_2 = b_1 : b_2 \\\Rightarrow \dfrac{42}{262.5} = \dfrac{12}{b_2}\\\Rightarrow b_2 = 75 cm[/tex]

Hence, base of larger triangle = 75 cm

Answer:

(a;b)={(17; 64); (64; 17)}

Step-by-step explanation:

a+b=81 => b=81-a

a*b=1088

a*(81-a)=1088

-a²+81a=1088

a²-81a+1088=0

a²-64a-17a+1088=0

a(a-64)-17(a-64)=0

(a-17)(a-64)=0

=> a=17 and a=64

for a=17 => b=81-17=64

for a=64 => b=81-64=17

(a;b)={(17; 64); (64; 17)}

The two integers are equal to a = 17 and b = 64.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The two integers are,

a+b=81 => b=81-a

a x b=1088

Calculate the value of one integer,

a x (81-a)=1088

-a²+81a=1088

a²-81a+1088=0

a²-64a-17a+1088=0

a(a-64)-17(a-64)=0

(a-17)(a-64)=0

Calculate the value of the second integer b,

=> a=17 and a=64

for a=17 => b=81-17=64

Therefore, the two integers are equal to a = 17 and b = 64.

Answer:

4.2 inches when rounded

Step-by-step explanation:

volume = pi(r²)h

155.09088in³ = pi(r²)2.8

÷2.8 ÷2.8

55.3896 =pi(r²)

÷pi ÷pi

17.6310572718 = (r²)

Then you have to square root both sides (I tried to use the radical symbol but it didnt work, sorry :( )

After you square root it you should get

Answer:

14 inches

Step-by-step explanation:

Length of the hole = 16(½) inches

Length of the dirt = 8(¾)inches

The distance between the top of the pile to the bottom of the hole = ?

Since the dirt is beside the hole and not inside the hole, we can find it's length using addition.

Distance from the top to the bottom = length of dirt + length of the hole

Length of dirt = 8×¾ = 6 inches

Length of the hole = 16 × ½ = 8 inches

Distance from the top of the dirt to the bottom of the hole = (6 + 8) inches

Distance from the top of the dirt to the bottom of the hole = 14 inches

Note: the only way we can use subtraction here is if the hole was filled with dirt, what's the distance that's left

Distance left = length of hole - length of dirt

Distance left = 8 - 6 = 2 inches .

But what the question requested was the distance from the top of the dirt to the bottom of the hole

Step-by-step explanation:

Given the expression:

[tex]log_{12}\dfrac{x^4\sqrt{x^3-2} }{(x+1)^5}[/tex]
