Answer:

7 to the 7th power

Step-by-step explanation:

To get your answer you add your two exponents together and that becomes your new exponent. Your base number stays the same..

The answer is 7 ⁷

Step-by-step explanation: 7 ⁴ is 343 and 7 ³ is 2401 so if you multiply those together it is

823,543. 7 ⁷ in total is 823,543

Answer:

I suppose that this refers to numbers like:

N = abcd

Where a, b, c and d are single digits.

We want to find the number of 4-digit numbers such that:

a, b, c and d are even numbers.

So let's count the number of options for each digit, where we impose that the possible digits must be even.

a: Here we have the options {2, 4, 6, 8} ( 0 is an even digit, but if we take a = 0, then this would be a 3 digit number) Then we have 4 options for a.

b: Here we have the options {0, 2, 4, 6, 8}. 5 options in total.

c: Here we have the options {0, 2, 4, 6, 8}. 5 options in total.

d: Here we have the options {0, 2, 4, 6, 8}. 5 options in total.

The total number of possible combinations will be equal to the product of the number of options for each selection.

C = 4*5*5*5 = 500

There are 500 "nice" numbers of 4-digits.

Answer:

She is not correct, the claim is wrong

Step-by-step explanation:

Here, we want to check if a claim

made is correct

We can represent the exponential function as;

y = I( 1 - r)^t

So in this case;

1 - r = 0.72

r = 1 - 0.72

r = 0.28

This is same as 28%

So what this mean is that we expect a decrease of 28% per day

There are 24 hours on a day

So the decrease per hour will be 28%/24 = 1.167%

So as we can see the claim is wrong

The model of the level of water in a draining pool is an illustration of an exponential function.

Inayah's claim is incorrect, because the water drains at 28% per hour

The function is given as:

[tex]\mathbf{y = 12(.72)^t}[/tex]

An exponential function is represented as:

[tex]\mathbf{y = a(1 - r)^t}[/tex]

Where r represents the rate.

So, by comparison

[tex]\mathbf{1 - r = 0.72}[/tex]

Collect like terms

[tex]\mathbf{- r = 0.72 - 1}[/tex]

[tex]\mathbf{- r = -0.28}[/tex]

Multiply both sides by -1

[tex]\mathbf{r = 0.28}[/tex]

Express as percentage

[tex]\mathbf{r = 28\%}[/tex]

This means that, the water drains at 28% per hour

Hence, Inayah's claim is incorrect

Answer:

my answer is incorrect

Step-by-step explanation:

Since the two shapes are similar, you can answer this question with a proportion.

[tex]\frac{12}{200} = \frac{15}{area} \\12area = 200*15\\area = \frac{200*15}{12} = 250[/tex]

Another way you could solve it is to find the percentage growth of the height of the area.

[tex]\frac{15-12}{12} = \frac{3}{12} = 25[/tex] percent growth.

We can multiply the area of A by 1.25 to find the area of B

[tex]200*1.25 = 250[/tex]

edit: I was incorrect, it is not linear.

It would be [tex]200*(1.25)^2[/tex]

all triangles equal 180°, it gives you two angles on each triangles. if you add them together and subtract that from 180 you'll get the final angle. the angles on both triangles Are 45,63, and 72. (they add up to 180) and because both triangles have two angels that are the congruent. they are similar by the Angle angle postulate.

Answer:

The least amount of pencils that can be bought is 7

Step-by-step explanation:

Step one:

Budget=$50

the cost of one binder= $7

then 5 binders will cost= 7*5= $35

the balance will be 50-35= $15

Step two:

let the number of pencils that can be bought be x

The cost of each pencil = $2

the remaining amount from the budget to get pencils is $15

Hence the number of pencils that can be bought is

x=15/2

x=7.5

The least amount of pencils that can be bought is 7

Answer: 1924

Step-by-step explanation:

Number if seats in the theater = 3700

Percentage of seats filled by students in the theater = 52%

The number of 6th graders that went on the trip will be gotten by multiplying 52% by 3700. This will be:

= 52% × 3700

= 52/100 × 3700

= 0.52 × 3700

= 1924

1924 students went on the trip

Answer:

Yes, you were correct with x=5. AB=CD=25 and AC=BD=23

Step-by-step explanation:

You already have x=5.

The first question is AB=CD=__ so you can just look at AB and you see it says 5x. You just substitute in the 5 for the x because you already got that. 5 times 5 = 25 and there is your first answer.

AC=BD=__ is your next question and you just look at AC and see "5x-2" and substitute in the x again. So you'll have 5(5)-2 which is 25-2 and your answer will be 23.

Yes, it is correct with x=5.It comes AB=CD = 25 and AC = BD=23.

Given that,

Based on the above information, the calculation is as follows:

AB = CD

Here AB = 5x

= 5(5)

= 25

So AB = CD = 25

Now

AC = BD

Here

AC = 5x - 2

= 5(5) - 2

= 25 - 2

=23

So AC = BD = 23

Therefore we can conclude that Yes, it is correct with x=5.It comes AB=CD = 25 and AC = BD=23.

Answer:

The statement "(a) all whole numbers are rational numbers" is true.

Step-by-step explanation:

A rational number is the number which can be expressed in the from  of  [tex]\frac p q[/tex], where p, q are integers and q\neq0.

(a.) As all the whole numbers (0,1,2,3...) can be expressed in the form of p/q having q=1.

Hence,  the statement "(a) all whole numbers are rational numbers" is true.

(b). As the rational numbers can have the fractional value but any integers don't have fractional value, so all the rational numbers are not integers.

Hence, the statement "(b). All rational numbers are integers" is not true.

(c). As the rational numbers can have the fractional value but any whole numbers don't have fractional value, so all the rational numbers are not whole numbers.

Hence, the statement "(c). All rational numbers are whole numbers." is not true.

(d). Integers( ...,-2,-1,0,1,2,...) can be negative, but the whole numbers (0,1,2,...) can't be negative. So, all integers can't be whole numbers.

Hence, the statement "(d). All integers are whole numbers" is not true.

Answer:

Step-by-step explanation:

(2) The sum of angles in a quad is always 360.

Take line RST and you get the value of angle RSP as 180 - 110 which is 70. This is due to them being linear pairs. Angles formed by a straight line is always 180 degrees!

110 + x = 180

x = 70

Now for y

Since we found values for all the 3 angles, which are 140, 110, 70, the 4th one is gonna be the sum of all the 3 angles subtracted from 360

140 + 110 + 70 + y = 360

y = 360 - (140 + 70 + 110)

y = 50 <- That's the answer.

(2) 2 of the angles are already given. If you look, angle U is 90 degrees. That's what the sign represents.

Angle Q (In the quad) is going to be 180 - 110 (Linear pairs) = 70

Since we found 3 angles the 4th one (angle R) is going to be 360 - (90 + 50 + 70) which is 360 - 210 which is 150.

Since angle R in the quad is 150, due to linear pair property, 3x = 180 - 150

3x = 30

x = 30/3 = 10

x = 10 <- That's the answer :D

A statistical chart called a dot chart or dot plot is made up of data points that are represented on a very basic scale, usually using filled-in circles. The dot chart comes in two widely used but quite different forms.

A statistical chart made up of data points drawn on a relatively basic scale is known as a dot diagram, sometimes known as a dot plot. One of the simplest statistical plots is the dot plot, which is typically applied to tiny data sets. They can be used to draw attention to outliers, gaps skew in the distribution and clusters.
