what does -5+3x equals

Answer:30

Step-by-step explanation:

30 times he can expect to spin a number less than 5.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

A spinner with six section numbered from 1 to 6.

total number of times spins = 150

So, the number of times the number comes less than 5 is

= 150 x 1/5

= 150/5

= 30

Answer:

4√2/7

Step-by-step explanation:

Suppose cos(x)=-1/3, where pi/2≤x≤ pi

tan(2x) = sin(2x)/cos(2x)

Since sin2x = 2sinx cosx

cos 2x = 2cos²x-1

Substitute

tan(2x) = 2sinx cosx/ 2cos²x-1

Given cosx = -1/3

adjacent = -1

hyp = 3

opp = √3²-(-1)²

opp = √9-1

opp = √8

sinx = opp/hyp

sinx = √8/3

tan(2x) = 2sinx cosx/ 2cos²x-1

tan(2x) = 2(√8/3)(-1/3)/ 2(-1/3)²-1

tan2x= (-2√8/9 )÷ (2/9 - 1)

tan2x = -4√2/9 * 9/-7

tan 2x = 4√2/7

Answer:

Step-by-step explanation:

Step 1: Find your legth and width

Length = x + 5

Width = 3

Step 2: Use area formula to find area

l x w = A

(x + 5) x 3 = A

A = 3(x+5)

Step 3: Therefore Statement

Thereforethe answer to the question is C. 3(x+5)

Answer:

C. 3(x + 5)

Step-by-step explanation:

area of rectangle = length * width = width * length

A = area of largest rectangle

a1 = area of left rectangle

a2 = area of right triangle

The largest rectangle is made up of the the two smaller rectangles.

A = a1 + a2

Left rectangle: a1 = WL = 3x

Right rectangle: a2 = WL = 3 * 5

Total area of the two small rectangles:

A = a1 + a2 = 3x + 3 * 5

Apply the distributive property in reverse to 3x + 3 * 5 by factoring out a 3:

A = 3x + 3 * 5 = 3(x + 5)

The area of the largest rectangle is 3(x + 5)

We can also find an expression for the area of the largest rectangle directly by looking at its length and width.

The length of the largest rectangle is x + 5.

The width of the largest rectangle is 3.

A = WL

Substitute 3 for W, the width.

Substitute x + 5 for L, the length.

A = 3(x + 5)

Answer: C. 3(x + 5)

Answer: C. y equals x

Step-by-step explanation: The earliest fractions were reciprocals of integers: ancient symbols representing one part of two, one part of three, one part of four, and so on.[28] The Egyptians used Egyptian fractions c. 1000 BC. About 4000 years ago, Egyptians divided with fractions using slightly different methods. They used least common multiples with unit fractions. Their methods gave the same answer as modern methods.[29] The Egyptians also had a different notation for dyadic fractions in the Akhmim Wooden Tablet and several Rhind Mathematical Papyrus problems.[citation needed]

The Greeks used unit fractions and (later) continued fractions. Followers of the Greek philosopher Pythagoras (c. 530 BC) discovered that the square root of two cannot be expressed as a fraction of integers. (This is commonly though probably erroneously ascribed to Hippasus of Metapontum, who is said to have been executed for revealing this fact.) In 150 BC Jain mathematicians in India wrote the "Sthananga Sutra", which contains work on the theory of numbers, arithmetical operations, and operations with fractions.

A modern expression of fractions known as bhinnarasi seems to have originated in India in the work of Aryabhatta (c. AD 500), Brahmagupta (c. 628), and Bhaskara (c. 1150). Their works form fractions by placing the numerators (Sanskrit: amsa) over the denominators (cheda), but without a bar between them. In Sanskrit literature, fractions were always expressed as an addition to or subtraction from an integer. The integer was written on one line and the fraction in its two parts on the next line. If the fraction was marked by a small circle or cross, it is subtracted from the integer; if no such sign appears, it is understood to be added.

Answer: x=8 angle BDC=77

Step-by-step explanation:

9x-12x=-19-5

-3x=-24

x=8

12x(8)-19

=77

(9x + 5) and (12x - 19) are one angle split equally.

(9x + 5) = (12x - 19)

The value of m∠BDC is 65°

It is a two-dimensional figure which has three sides and the sum of the three angles are equal to 180 degrees.

We have,

(9x + 5) and (12x - 19) are one angle split equally.

So,

9x + 5 = 12x - 19

We will solve for x.

9x + 5 = 12x - 19

Add 19 on both sides.

9x + 5 + 19 = 12x

Subtract 9x on both sides.

24 = 12x - 9x

24 = 3x

Divide both sides by 3.

24/3 = x

x = 7

Now,

The value of m∠BDC.

= 12x - 19

= 12 x 7 - 19

= 84 - 19

= 65°

Thus,

The value of m∠BDC is 65°

SA = 126 square cm

Step-by-step explanation:

SA = 2(l · w) + 2(h · w) + 2(l · h)

SA = 2(5 · 6) + 2(6 · 3) + 2(5 · 3)

SA = 60 + 36 + 30

SA = 126 sq cm  

The surface area of the cuboid box is S = 126 cm²

What is the surface area of cuboid?

A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges

The total surface area of the cuboid is given by the formula

Surface Area = 2 ( LH + LW + HW )

where ,

Length of the cuboid = L

Width of the cuboid = W

Height of the cuboid = H

Given data ,

Let the surface area of cuboid be S

Length of the cuboid = L = 6 cm

Width of the cuboid = W = 5 cm

Height of the cuboid = H = 3 cm

On simplifying , we get

Surface Area = 2 ( LH + LW + HW )

S = 2 ( ( 6 x 5 ) + ( 6 x 3 ) + ( 5 x 3 ) )

S = 2 ( 30 + 18 + 15 )

S = 2 ( 63 )

S = 126 cm²

Hence , the surface area is S = 126 cm²
