The difference of a number and 12 is 34. Find the number

The total money earned by Monique can be written as a expression as 12h + 20.

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The earning per hour working as lifeguard is $12.

And, the earning from dog city is $20.

Suppose the number of hours worked as lifeguard be h.

Then, the money earned working as lifeguard is 12h.

Now, the expression for total money earned can be given as,

12h + 20

Hence, the expression for the total earning can be given as 12h + 20.

Answer:

[tex]f(x)=(\frac{1}{4})^{x-b}[/tex]

Step-by-step explanation:

We are given that

(0,1024),(1,256),(2,64),(3,16)and(4,4)

From given data we assume an exponential function

[tex]f(x)=a^{b+x}[/tex]

where b and a are constant

[tex]f(0)=1024[/tex]

[tex]1024=a^b[/tex]...(1)

[tex]f(1)=256[/tex]

[tex]256=a^{b+1}[/tex]...(2)

Equation (1) divided by equation (2)

Then, we get

[tex]\frac{1024}{256}=\frac{a^{b}}{a^{b+1}}[/tex]

[tex]4=a^{-1}[/tex]

[tex]a=\frac{1}{4}[/tex]

Using the the value of a in equation (1)

[tex]1024=(\frac{1}{4})^{b}[/tex]

[tex]4^{5}=4^{-b}[/tex]

[tex]-b=5[/tex]

[tex]b=-5[/tex]

Therefore, the exponential  function

[tex]f(x)=(\frac{1}{4})^{x-b}[/tex]

Answer:

d. x = 45°, y = 13.1√2

Step-by-step explanation:

Due to it being a square, each corner is 90°. The angle bisector splits the square into two triangles. These triangles are 45° 45° 90° triangles.

Half of 90° is 45°, therefore x = 45°.

When you have a 45° 45° 90° triangle, the legs of the triangle will equal each other and the hypotenuse will be the side length multiplied by √2. Therefore, y = 13.1√2.

Answer:

(x, y) → (-x, -y)

Q"(4, 1) → Q'(-4, -1)

R"(6, -5) → R'(-6, 5)

Total money would Jayden have to pay for parking after addition of automatic fee and additional fee is,

1.  $21

2. $12

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.

Given that,

Jayden is driving to a concert and needs to pay for parking

There is an automatic fee of $9 just to enter the parking lot

when he leaves the lot, he will have to pay an additional $3 for every hour

Total money = ?

1. When he left the parking after 4 hours

Total money = automatic fee + additional fee

                     =  9 + (3×4)

                     =  $21

2. When he left the parking after 1 hours

Total money = automatic fee + additional fee

                     =  9 + (3×1)

                     =  $12

Hence, the fee is respectively for both the cases are $21, $12

Answer:

The probability is 0.9

Step-by-step explanation:

We start by calculating the density function

That will be;

f(x) = 1/(b-a)

b and a are the extremes

from the question,

a = 15

b = 65

So f(x)

= 1/(65-15) = 1/50 = 0.02

The probability we want to calculate is;

P( x > 20)

The termination point is 65

So the probability will be

(65-20) * 0.02

= 0.9

Answer:

1 : 3

Step-by-step explanation:

¼ of the biscuits are chocolate while the rest are plain.

Since a fraction is a part of a whole, 1, then it means that the fraction that are plain is:

1 - ¼ = ¾

Therefore, the ratio of chocolate biscuits to plain biscuits is:

¼ : ¾

To put this in simplest dorm, multiply both sides by 4, we have:

1 : 3

This is the ratio of chocolate biscuits to plain biscuits.

Answer:

Each population must be at least 10 times as large as its corresponding sample.

Step-by-step explanation:

The 10 percent rule checks that the sample is small relative to the population (that is, that the population is at least 10 times as large as the sample size) so that independence of observations within a sample is reasonable to assume.

The check that must be made is (b)  Both population must be approximately normal

From the question, we have the following highlights

When the above highlights are true, then the population where the samples are to be selected must be approximately normal

Hence, the check that must be made is (b)  Both population must be approximately normal

Answer:

The correct option is C : x² + (y +3)² = 9 .

Step-by-step explanation:

We know that the general equation for a circle is ( x - h )² + ( y -k )²= r², Where,

Let the point be ( 0 , -y) , since it is on negative y axis . And the circle passes through the origin that is (0,0) . Hence the center will be 3 units down the y - axis that is ( 0 , -3) .Hence h will be 0 and y = (-3) .

Now its given that the radius of the circle is 3. So on substituting r = 3 , in standard form we have ,

⇒ ( x -h )² + ( y - k )²= r²

⇒ ( x - 0)² + { y - (-3) }² = 3²

⇒ x² + ( y + 3) ² = 3²

⇒ x² + ( y + 3)² = 9

Answer:

False

Step-by-step explanation:

Given

[tex]XLIV = 64[/tex]

Required

True or False

The above numeral can be split as follows:

[tex]XLIV = XL + IV[/tex]

X means 10 and L means 50.

But because X (10) which is smaller comes before L (50), XL is executed as:

[tex]XL = -10 + 50[/tex]

[tex]XL = 40[/tex]

In Roman numerals;

[tex]IV = 4[/tex]

Substitute 40 for XL and 4 for IV.

[tex]XLIV = 40 + 4[/tex]

[tex]XLIV = 44[/tex]

Hence;

[tex]XLIV = 64[/tex] is false
