Step-by-step explanation:

You're welcome.

The number of days took to get the video of Felipe 1024 views is 4.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

The relationship between the elapsed time in days, d, since the video was uploaded and the total number of views, v, that the video received is modeled by the equation,

v = 4^(1.25d)

We have to find d when v = 1024

1024 = 4^(1.25d)

We have the rule for exponents aᵇⁿ = (aᵇ)ⁿ

1024 = [tex](4^{1.25} )^d[/tex]

1024 = (5.6569)^d

Taking logarithms on both sides,

㏒ (1024) = ㏒ [(5.6569)^d]

We have the exponent rule for logarithm, ㏒ (aᵇ) = b ㏒ (a)

㏒ (1024) = d ㏒ (5.6569)

d = ㏒ (1024) / ㏒ (5.6569)

d = 4

Hence it took 4 days to for Felipe's video to get 1024 views.

Answer:

Step-by-step explanation:

Final answer: Lily received 10 postcards from Thailand.

Explanation: Number of postcards=50

Percentage of postcards from thailand= 16

Number of postcards from Thailand= 16/100*50= 8

Now, he received some postcards from Thailand. Let the number of postcards received from Thailand be x. Therefore,

Number of postcards=50+x

Number of postcards from Thailand= 8+x

We know that the percentage of postcards from Thailand now is 30.

Therefore,

30=(8+x/50+x)*100

0.3(50+x)=8+x

15+0.3x=8+x

0.7x=7

x=10

  $150               $300             $450              $600              $750

Step-by-step explanation:

The table shows tickets #1-5, but if you want to go up to tickets #6 and #7, then Ticket #6 would be $900, and Ticket #7 would be $1,050. Due to each ticket being equivalent to $150, you get your answer by adding 150 for each ticket or multiplying 150 × 7.

The total volume of the toy is 497.4192cm³ with 340.3392 cm³ being the volume of the top solid and 157.08 cm³ being the volume of the bottom solid.

Volume is the quantity of space a thing occupies, whereas capacity is a measure of the substance it can store, such as a solid, a liquid, or a gas.

While capacity can be measured in virtually any other unit, such as liters, gallons, pounds, etc., volume is measured in cubic units.

So, the volume of the cone:

V = πr²h/3

Now, invert values:
V = π5²*13/3

V = 340.3392 cm³

The similar, volume of a cylinder:

πr²h

Now, insert values as follows:

πr²h

π5²2

V = 157.08 cm³

Total volume: 340.3392 cm³+157.08 cm³ = 497.4192cm³

Therefore, the total volume of the toy is 497.4192cm³ with 340.3392 cm³ being the volume of the top solid and 157.08 cm³ being the volume of the bottom solid.

The Pythagorean theorem is a fundamental result in mathematics named after the ancient Greek mathematician Pythagoras. It states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Perimeter is a measure of the distance around the outside of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape. The formula for perimeter depends on the shape. For example, the perimeter of a rectangle is twice the sum of its length and width, while the perimeter of a circle is equal to its circumference.

The markup, expressed as a percentage of the cost, is the difference between the selling price and the product's cost.The gross profit of a unit is determined by subtracting its cost to produce or acquire for resale from its sales price to determine the markup percentage.

Below, you'll find various possible formats for the markup formula or equation.

The selling price given as = $ 15

The cost per CD is = $ 11

The total profit = Selling price - Cost

Total profit per CD = $ 15 - $ 11

Total profit per CD = $ 4

Answer:

m∠B = 83°

EF = 10

Step-by-step explanation:

Two triangles are similar if their corresponding angles are the same size.

Therefore if ΔABC ~ ΔDEF then:

Interior angles of a triangle sum to 180°:

⇒ m∠A + m∠B + m∠C = 180°

⇒ 24° + m∠B + 73° = 180°

⇒ m∠B + 97° = 180°

⇒ m∠B = 83°

In similar triangles, corresponding sides are always in the same ratio.

Therefore if ΔABC ~ ΔDEF then:

⇒ AB : DE = BC : EF = CA : FD

⇒ 12 : DE = 8 : EF = 16 : 20

Therefore, to find the length of EF:

[tex]\implies \sf 8 : EF = 16 : 20[/tex]

[tex]\implies \sf \dfrac{8}{EF} = \dfrac{16}{20}[/tex]

[tex]\implies \sf 8 \cdot 20= 16 \cdot EF[/tex]

[tex]\implies \sf160= 16 \cdot EF[/tex]

[tex]\implies \sf EF=\dfrac{160}{16}[/tex]

[tex]\implies \sf EF=10[/tex]

The solution for the given decimal multiplication is 0.025.

To multiply two decimal numbers, first multiply the values without the decimal points.

The digits in the factors that follow the decimal point should now be added together.

Following that, the dot should be placed in the product so that it has the same number of digits as the total number of factors.

If there are more decimal places than digits in the number, place zeroes immediately after the dot.

If there are more decimal places present compared to digits in the product, fill the decimal places with zeroes immediately after the dot.

For the given question, multiply -5 * -5 = 25

Now the total digits after the decimal point in factors are 3.

But there are only 2 digits in 25.

So fill the decimal place with a zero.

Therefore the product of given decimal numbers is 0.025.

A number that divides another number by itself with no residual is known as a factor. In other words, if multiplying two whole numbers results in the creation of a product, the numbers we are multiplying are factors of the product since the product is divisible by them. Division and multiplication are the two ways to discover factors. A number or other mathematical object is factorized or factored in mathematics by expressing it as the product of numerous factors, often smaller or simpler things of the same sort.

Therefore , the solution to the given problem of triangle comes out to be x =20 degree and y = 20 degree.

In a plane, any three points can be joined to form triangles, that have 3 components and three angles. They were among the first geometrical forms to be investigated. Because each polygon, regardless of its number of sides (four, five, six, or n), may be divided into a triangle, they are especially significant.

Here,

Given : 140 degree

Since it is a scalar triangle

two sides will have equal angle,

Thus ,

x=y
