Answer:

7     14    21     35

3     6      9     15

not decimals for every 3 cat 7 dog

Step-by-step explanation:

so, you take 7+7 to get 14 then just repeat 14+7 = 21

                    3+3              6    

and for 35 just take 35 divided by 7 * 3 to get 15

Answer:

C) (-2, -1)

Explanation:

The graphs meet at the point (-2, -1), therefore C is the solution.

Answer:

1/2

Step-by-step explanation:

There are a total of 25 students. 3 don't study art or biology. 10 study only biology. 6 study both art and biology. This means the remaining students only study art.

1. Calculate the number of students taking art

only art: 25 - 3 - 6 - 10 = 6

number of students taking art and biology: 6

total number of students taking art: 12

2. Calculate the probability

Out of the 12 total students taking art, 6 are in art and biology.

6/12 = 1/2  

Probability that the student studies Art and biology is; P(A n B) = ½

We are given;

Total number of students in the group; n = 25 students

Number that study both art and biology; n(A u B) = 6

Number that study biology but not art; n(B u A') = 10

Number that study none of the 3 subjects; n(A' u B') = 3

Now;

Number that study only arts is; n(A n B') = 25 - 6 - 10 - 3 = 6

Since n(A u B) = 6

Then;

n(A) = n(A u B) + n(A n B')

n(A) = 6 + 6

n(A) = 12

Thus;

Probability that the student studies Art and biology is;

P(A n B) = 6/12

P(A n B) = ½

A. 3.25

Step-by-step explanation:

A kitten who is just born is predicted to weigh 3.25 ounces and its weight is predicted to increase by 0.3 ounces. Then the correct option is A,D.

1. The 0.3d is the day each day

So

==> 0.3d +3.25(the first day born) ==> w ( means the d is the day so it increase 0.3 per day)

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

Where m is the slope of the line and c is the y-intercept of the line.

Information was gathered on the weight, in ounces, of cats for the initial three months after birth. A line of fit was drawn through the dispersed plot and had the condition w = 3.25 + 0.3d, where w is the heaviness of the cat in ounces and d is the age of the little cat in days.

A kitten who is just born is predicted to weigh 3.25 ounces and its weight is predicted to increase by 0.3 ounces. Then the correct option is A.

To write 7^3 x 7^2 using a singular exponent, you can add the exponents together since the bases (7) are the same. The result is:

Answer:

volume = length×width×height

Step-by-step explanation:

box 1

12×2×7 = 24×7 =168

box 2

9×2×5 = 10×9 = 90

total vloume = 168+90 = 258cubic inches.

Answer:

258 cubic inches

Step-by-step explanation:

Shape one has dimensions of: height 12in, width 7in, and depth 2in

Multiply those together you get the volume or 168 cubic inches.

Then you have to multiply the dimensions of the second shape which are : height 5in, width 9in, and depth 2in to get a volume of 90 cubic inches for the second shape.

Then you add the two volumes together to find the total volume

168 cubic inches + 90 cubic inches = 258 cubic inches

Answer:

6.68 units (2 d.p.)

Step-by-step explanation:

The formula for the volume of a cylinder is:

\(\boxed{V=\pi r^2 h}\)

where:

Given values:

To find the height of the cylinder, substitute the given values into the formula and solve for h:

\(\implies 189=\pi \cdot 3^2 \cdot h\)

\(\implies 189=9\pi \cdot h\)

\(\implies \dfrac{189}{9 \pi}=\dfrac{9\pi \cdot h}{9 \pi}\)

\(\implies \dfrac{189}{9 \pi}=h\)

\(\implies h=6.6845076...\)

Therefore, the height of a cylinder with a radius of 3 units and a volume of 189 cubic units is 6.68 units (2 d.p.).

Answer:

h≈6.68

6.68 is the height of a cylinder with a radius of 3 and a volume of 189

Answer:

It is the third option.

Step-by-step explanation:

Use math techniques to solve.

Given, (2 ^ (-3))^7

= 2 ^ (-3 * 7)

= 2 ^ (-21) ⇒ Option (C)

= 1/(2 ^ 21) ⇒ Option (D)

= 1/(2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2)

= 1/(4 * 4 * 4 * 4 * 4 * 4 * 4 * 4 * 4 * 4 * 2)

= 1/(16 * 16 * 16 * 16 * 16 * 2)

= 1/(256 * 256 * 32)

= 1/(65536 * 32)

= 1/2097152

So, Option (C) and (D) are correct

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

I'm assuming it's asking what you need to put in the "dot", or in other words what exponent does it have to be, so the two expressions are equal.

Anyways, there's an exponent identity, which essentially states: \(\frac{x^a}{x^b}=x^{a-b}\)

So in this case, let's just say that "dot" is x, to make it a bit easier to express

You have the following equation: \(\frac{3^x}{3^2}=3^4\)

But remember the identity? So it follows that: \(\frac{3^x}{3^2}=3^{x-2}\)

So if we substitute this in, as the fraction we get the equation: \(3^{x-2}=3^4\)

Since the two bases are the same, the exponents have to be the same, so we can write the equation as: \(x-2=4\)

And this is a simple algebraic equation, which you just add 2 to both sides to get: \(x=6\)

Now, that's not to difficult, but I want to go a bit more in depth as to why the identity: \(\frac{x^a}{x^b}=x^{a-b}\) intuitively makes sense if you think about it for a bit.

So I can use an abstract example, but I'll use this specific example: \(\frac{3^6}{3^2}=3^4\)

The reason for this, is because if you write out the exponent in multiplication form you get: \(\frac{3*3*3*3*3*3}{3*3}=3*3*3*3\)

So what we're really doing here, is cancelling out two of the threes. The reason for this is because we have two threes in the numerator, and two in the denominator. So we can just cancel out two of them from the numerator, and this gives us the expression: \(3*3*3*3\)

This is just 4 threes being multiplied by each other, which can also be expressed as: \(3^4\)

So when you're writing: \(\frac{x^a}{x^b}=x^{a-b}\), you're just cancelling out x's from the numerator and denominator.

Answer: $88

Step-by-step explanation:

1. Plug in the given data into the formula.

p = 80

r = 0.1 (represents 10%)

t = 1 year

2. Solve for i based on the formula's values

i = (80)(0.1)(1) = 8

Interest earned is $8 but THIS IS NOT THE FINAL ANSWER!

3. Add i (interest) to p (starting amount)

Elena started with $80, so the interest of $8 is added for a final answer of $88 after one year.

Answer:

Step-by-step explanation:

As per the given data, Alicia can accommodate 17 more people without reserving another bus.

A field trip is a type of educational excursion that is usually organized by schools, colleges, or other educational institutions.

Alicia has already reserved 3 buses since 3 x 36 = 108 people can fit on those buses.

There are 127 - 108 = 19 people who have not been accounted for on those buses.

Since each bus holds 36 people and there are 19 people who still need to be accounted for, Alicia can still add 36 - 19 = 17 more people before she needs to reserve another bus.

Therefore, Alicia can still sign up 17 more people before needing to reserve another bus.

Step-by-step explanation: 4x-9=31

                                             4x=31+9

                                             4x=40

                                             4x/4=40/4

                                             x=10  

Answer: 10. 4(10)-9=31

Step-by-step explanation:

firstly, we would substitute the values given in the subset to the value of x and check which solves the equation.

When x= (-10),

4(-10) -9

= -40-9

=-49,

which does not equal 31, so it cannot be -10.

Similarly, when x=5.5,

4(5.5)-9

=22-9

= 13

which does not equal 31.

Thirdly, when x=9

4(9) -9

= 36-9

= 27

which does not equal 31.

Finally,

when x=10,

LHS 4(10)-9

=40-9

=31 RHS

Therefore x=10.
