Answer: 37.5

Explanation: find the surface area of one side, which is 2.5*2.5=6.25 then multiply that product by six, since there’s six sides in a square, and you’ll get 37.5

Answer:

I will do only 1 sum bru.h

In the 1st sum

the 1st no. can be in 9 ways

the 2nd no. can be in 10 ways

the 3rd no. can be in 10 ways

the 4th no. can be in 10 ways

total no. of ways = 9 × 10 × 10 × 10

= 90 × 100

= 9000 ways

2nd one..

the 1st letter can be written in 4 ways

the 2nd letter can be written in 4 ways

the 3rd letter can be written in 4 ways

the 4th letter can be written in 4 ways

Total no. of ways = 4 × 4 × 4 × 4

= 16 × 16

= 196 ways

Answer:

Step-by-step explanation:

Given : the ratio of red marbles to blue marbles is 6 to 22

But ,we want to write the ratio in simplest form

therefore ,we have to divide both sides of the ratio by their greatest common factor GCF.

→ So Let’s find the GCF(6 , 22)

Since 6 = 2 × 3

         22 = 2 × 11

then ,GCF(6 , 22) = 2

Eventually ,the ratio 6 : 22 in its simplest form I suppose 3 : 11

Step-by-step explanation:

Since, the fundraiser only have three prices for books($2, $5 and $10), the number of $5 book that was sold is 12.

The fundraiser only have 3 prices for books which are $2, $5 and $10.

There were 6 more $5 books sold than $10 books sold.

Let

x = number of $10 book sold

Therefore,

number of  $5 books sold = x + 6

There are 8 more $2 book sold than $10 book sold. Therefore,

number of  $2 books sold = x + 8

A total of $250 was raised.

Therefore, the total amount sold forms the following equation:

10x + 5(x + 6) + 2(x + 8) = 250

10x + 5x + 30 + 2x + 16 = 250

17x = 250 - 30 - 16

17x  = 204

x = 204 / 17

x = 12

Answer:

DC = 39

Step-by-step explanation:

From inspection of the diagram:

The tangent of a circle is always perpendicular to the radius, therefore:

DE ⊥ EA and CA ⊥ EA

As ∠DEB and ∠BAC are both 90°, then DE is parallel to CA.

Therefore, ∠DBE and ∠ABC are vertically opposite angles, and are therefore equal.

As triangles ΔBED and ΔBAC have two pairs of corresponding congruent angles, the triangles are similar.

Therefore:

[tex]\implies \sf \dfrac{DE}{CA}=\dfrac{EB}{BA}[/tex]

[tex]\implies \sf \dfrac{10}{5}=\dfrac{24}{BA}[/tex]

[tex]\implies \sf BA=12[/tex]

Using Pythagoras' Theorem for ΔBED to find DB:

[tex]\implies \sf DE^2+EB^2=DB^2[/tex]

[tex]\implies \sf 10^2+24^2=DB^2[/tex]

[tex]\implies \sf DB^2=676[/tex]

[tex]\implies \sf DB=\sqrt{676}[/tex]

[tex]\implies \sf DB=26[/tex]

Using Pythagoras' Theorem for ΔBAC to find BC:

[tex]\implies \sf CA^2+BA^2=BC^2[/tex]

[tex]\implies \sf 5^2+12^2=BC^2[/tex]

[tex]\implies \sf BC^2=169[/tex]

[tex]\implies \sf BC=\sqrt{169}[/tex]

[tex]\implies \sf BC=13[/tex]

Therefore, the distance between the center of the circles DC is:

[tex]\begin{aligned} \implies \sf DC & = \sf DB + BC\\& = \sf 26 + 13\\& = \sf 39\end{aligned}[/tex]

Use Pythagorean theorem

Now use proportion

Now

DC=DB+BC=26+13=39

Answer:

IQR = 5

Step-by-step explanation:

the IQR is the difference between the upper quartile Q₃ and the lower quartile Q₁

Q₃ is the value at the right side of the box plot , that is

Q₃ = 51

Q₁ is the value at the left side of the box plot , that is

Q₁ = 46

then

IQR = Q₃ - Q₁ = 51 - 46 = 5

We will see that the system of equations has infinite solutions, each of the form:

y = (3/2)*(x + 1)

Here we have the system:

3x - 2y = -3

-9x + 6y = 9

Notice that if we add 3 times the first equation to the second one, we get zero.

3*(3x - 2y) + -9x + 6y  = 3*(-3) + 9

9x - 6y - 9x + 6y = -9 + 9

0 = 0

This actually means that both equations represent the same line, then, the "two" lines intersect in infinite points, meaning that the system of equations has infinite solutions, which are of the form:

3x - 2y = -3

2y = 3 + 3x

y = (3/2)*(x + 1)

The value of the constant of variation is one-fourth. Then the correct option is A.

The term "constant of variation" refers to the fact that the relationship between variables remains constant.

The formula will be

y = kx

where k is the variation constant.

When f = 2 and g = 8, n = 4. if n varies jointly with f and g, then the equation will be

n = kgf

Then the value of k will be

Answer:

Keep it simple. Answer: A

Step-by-step explanation:

Answer:

69.5 if C and D both add up to 90, M=90 if both angles C and D were complementary to combine to a supplementary.

Step-by-step explanation:

You're trying to find m which is a variable for measurement for the "D" angle.

Info Given:

20.5 for angle C

Unknown for angle D

Both angles are Complementary.

_____________________________________________

I have 2 answers for this (The question was stated unclearly so I have 2 interpretations of this)

1st Answer:

If you're asking to solve for M but the C and D angles add up to 90 then do

90 - 20.5 = 69.5

2nd Answer:

We know that both angles are complementary which are 90-degree angles.

If we combine them then the angles add up to 180.

So C and D add up to form a Supplementary Angle.

20.5+69.5 + m = 180

Then M could possibly be 90.

The given expression is,Use property of logarithm

The value of log(0.5) is -0.30103.

The value of given expression is -4.81648.

If the final answer appromatted to preceding integer, then the correct option is -4.00.Step-by-step explanation:

The value of the [tex]log_{0.5}[/tex] (16) will be -4.00 so the correct option will be (A).

The exponent indicates the power to which a base number is raised to produce a given number called a logarithm.

A logarithm is a power to which a number must be raised in order to get some other number.

A logarithm is useful to find out the values on which power has a variable.

In another word, a logarithm is a different way to denote any number.

If you want to write 1 in logarithm then it will be log(base).

[tex]log_{a}[/tex] (x) = b ⇒ [tex]a^{b}[/tex] = x.

Let's say the given number is x then

x = [tex]log_{0.5}[/tex] (16)

[tex]0.5^{x}[/tex] = 16

Take log by both sides

Log[tex]0.5^{x}[/tex] = log 16

By log property

x log 0.5 = log 16

x = -4.00 hence, the correct answer to the given question will be -4.00.
