Answer:

8 pizzas

Step-by-step explanation:

If each of the 20 people eats 3/8 of pizza, to calculate the total number of pizzas needed, multiply 20 by 3/8 and round up to the nearest whole number.

[tex]\sf total \ number \ of \ pizzas=20 \times\dfrac38[/tex]

                                  [tex]=\dfrac{20 \times3}8[/tex]

                                  [tex]=\dfrac{60}8[/tex]

                                  [tex]=\dfrac{15}2[/tex]

                                  [tex]=7.5[/tex]

Therefore, he should buy 8 pizzas for the party.

Answer: C, D

Step-by-step explanation:

Consider the missing lines of question are "Due to the Enhanced Community Quarantine, Grand Royal Spa temporarily stopped its operation and to help the employees, the owner decided to split evenly its total revenue of 65,000.00".

Given:

Total revenue = 65000

Number of employees = x

To find:

The function which represents the  amount each received.

Solution:

We know that,

[tex]\text{Amount each received}=\dfrac{\text{Total revenue}}{\text{Number of employees}}[/tex]

Substitute the given values in the above formula.

[tex]\text{Amount each received}=\dfrac{65000}{x}[/tex]

So, the function which represents the  amount each received is

[tex]f(x)=\dfrac{65000}{x}[/tex]

Therefore, the required function is [tex]f(x)=\dfrac{65000}{x}[/tex].

Answer:

13 hours

Step-by-step explanation:

567/9= 63 mile per hour

819/63 = 13

13 hours

Answer:

13 hours

Step-by-step explanation:

how long does she drive in one hour?

567/9=63

she drives 63mph

819/63=13

it will take her 13 hours to drive 819 miless

Solution,

The population of a city is 2,549,786.

We can convert it into nearest million as follows :

Million = 10 lakhs

Rounding off to the nearest million

2,549,786 = 3,000,000

There are 6 zeroes after 3. We can express as the product of a single digit and a power of 10 as follows :

[tex]3,000,000=3\times 10^6[/tex]

Hence, the population of the city is 2,549,786 or [tex]3\times 10^6[/tex].

The expression which is equivalent to Start Fraction 5 y cubed Over (5 y) Superscript negative 2 Baseline End Fraction is

[tex]125y^5[/tex]

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

To find the equivalent expression, simplify the provided function using the mathematical operations.

The given algebraic expression is,

[tex]\dfrac{5y^3}{(5y^{-2})}[/tex]

Suppose the equivalent expression of this fraction is n. Thus,

[tex]n=\dfrac{5y^3}{(5y^{-2})}\\\\n=\dfrac{5y^3}{((5)^{-2}y^{-2})}\\[/tex]

In the division the power of the same number is subtracted. Therefore,

[tex]n=(5)^{1-(-2)}(y)^{3-(-2)}\\n=5^3\times y^5\\n=125y^5[/tex]

Hence, the expression which is equivalent to StartFraction 5 y cubed Over (5 y) Superscript negative 2 Baseline EndFraction is

Answer:

[tex]x=6[/tex]

Step-by-step explanation:

Using the given measurements of the angles and the lengths of the sides, we can determine that this figure must be a rectangle.

Diagonals of a rectangle are always equivalent/congruent.

We can use this information to set up an equation:

[tex]DF=EG\\7x-3=5x+9[/tex]

Add 3 to both sides:

[tex]7x-3+3=5x+9+3\\7x=5x+12[/tex]

Subtract 5x from both sides:

[tex]7x-5x=5x-5x+12\\2x=12[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{12}{2}\\x=6[/tex]

Answer:

[tex] \: [/tex]

Step-by-step explanation:

A rectangle is a parallelogram with equal angles and the diagonals of a rectangle are of equal length.

Therefore,

[tex] \\ { \longrightarrow \qquad{ \sf{ \pmb {DF = EG}}}} \: \: \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ \sf{ \pmb {7x - 3 = 5x + 9}}}} \: \: \\ \\[/tex]

Subtracting 5x from both sides we get :

[tex]{ \longrightarrow \qquad{ \sf{ \pmb {2x - 3 = 9}}}} \: \: \\ \\[/tex]

No, the correct answer is 32cm.

Step-by-step explanation:

First of all, lets cut the shape into two. A rectangle and a triangle. This will help us find the slanted side of the shape.

We will use the pythagorean theorem to find the length of the slanted line.

The pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex].

Input the given information of the triangle lengths that we know; that is the length= 6 and the base=3.

[tex]c= \sqrt{a^{2}+b^{2} } =\sqrt{6^{2}+\ 3^{2} } = 6.7082[/tex]

Now, we round.

Step-by-step explanation:

I am not sure I understand the question with all the typos and potentially missing parts.

as I understand it, it will take her 4 hours to reach her destination when going 15 mph.

and the question is how long the trip will take, if she travels at 12 mph.

4 h × 15 m/h = 4 × 15 m = 60 miles

that is the distance of her trip.

when going slower, the distance is of course still the same, only the needed time changes :

x h × 12 m/h = 60 m

x × 12 m = 60 m

x = 60/12 = 5 hours

the trip would take her 5 hours to complete (instead of 4).

Answer:

Length of the rectangle = 14.5 inches

Width of the rectangle = 37.5 inches

Step-by-step explanation:

Let the length of a rectangle = a inches

Since, width of the rectangle is 6 inches less than 3 times the length,

w = 3a - 6

Perimeter of the rectangle = 104 inches

Formula to calculate the perimeter of a rectangle = 2(length + width)

104 = 2[a + (3a - 6)]

2a + 2(3a - 6) = 104 → [Starting equation]

8a - 12 = 104 → [Distributive property]

8a - 12 + 12 = 104 + 12 → [Addition property of equality]

a = [tex]\frac{116}{8}=14.5[/tex] → [Division property of equality]

a). width of the rectangle = (3a - 6) = 37.5 inches

b). length of the rectangle = 14.5 inches

The width of the rectangle is 37.5 inches and the length of the rectangle is 14.5 inches.

The perimeter of a rectangle is represented as follows:

perimeter = 2l + 2w

where

w = width

l = length

Therefore,

perimeter = 104 inches

let

the length = a

Therefore,

width = 3a - 6

Therefore,

104 = 2a + 2(3a - 6)

104 = 2a + 6a - 12

116  = 8a

a = 116 / 8

a = 14.5  inches

width = 3(14.5 ) - 6 = 37.5  inches

Therefore, the width of the rectangle is 37.5 inches and the length of the rectangle is 14.5 inches.

The true solution to the logarithmic equation log(x)+log(x+5)=log(6x+12) is 4 option second is correct.

It is given the logarithmic equation [tex]\rm logx+log(x+5)=log(6x+12)[/tex].

It is required to find the true solution to the above logarithmic equation.

It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.

[tex]\rm a^b=c\\[/tex]

By using log property:

[tex]\rm log((x)(x+5))=log(6x+12)[/tex]
