Katelyn says that her biology test scores are much higher than her math test scores. Based on the shape of the data, which explains whether Katelyn is correct?

Answer:

Angles 1 & 2 are vertical angles, and angles 3 & 4 are adjacent angles.

Step-by-step explanation:

Vertical angles are angles across from each other. Adjacent angles are always beside each other.

It's not a linear pair because a linear pair is adjacent angles that add up to 180°, which is not true for your 2 angles in the picture. Hope this helps!!!

Answer:

The property of equality that justifies going from the first statement to the second statement  is;

Subtraction property of equality

Step-by-step explanation:

The given equation is presented here as follows;

AB + BC = 42

AB = 42 - BC

The above equation can be simplified as follows;

AB + BC = 42

AB + BC - BC = 42 - BC

(+ BC - BC = 0)

Therefore, we have;

AB + BC - BC = AB + 0 = AB = 42 - BC

AB = 42 - BC  which is the subtraction property of equality

For the subtraction property of equality, when we subtract a value from one side of the equation, we must subtract the same value from the side of the equation as follows

Given that the letters a, b, and c represent any numbers

When we have;

a = b

Then we also must have;

a - c = b - c

Answer:

1/6

Step-by-step explanation: in a rate you need to make it a one so you double the 1/2 gallon to make it one gallon then since you doubled that you have to double the days to 6. So they drink 1 gallon per 6 days.

Step-by-step explanation:

Emilia = 2 cups of grape juice for every 5 cups of pineapple juice

We can simplify this to 1 cup of grape juice for every 2 1/2 cups of pineapple juice

Darnell = 1 cup of grape juice for every 4 cups of pineapple juice

You can see the difference

Answer: 3x -6 (x+2)-(x+5)

Step-by-step explanation:

Distribute the Negative Sign:

=3x−6(x+2)+−1(x+5)

=3x+−6(x+2)+−1x+(−1)(5)

=3x+−6(x+2)+−x+−5

Distribute:

=3x+(−6)(x)+(−6)(2)+−x+−5

=3x+−6x+−12+−x+−5

Combine Like Terms:

=3x+−6x+−12+−x+−5

=(3x+−6x+−x)+(−12+−5)

=−4x+−17

Step-by-step explanation:

Answer:

Water in 3 hours = 450 gallons

Step-by-step explanation:

Given that:

Water flows at a rate of 25 gallons in 10 minutes.

10 minutes = 25 gallons

1 minute = [tex]\frac{25}{10}[/tex] = 2.5 gallons

Now,

Time = 3 hours

3 hours = 180 minutes

Quantity of water in 3 hours = 2.5 * 180

Quantity of water in 3 hours = 450 gallons

Hence,

Water in 3 hours = 450 gallons

Given :

There are currently 260 people in archery clubs across the city, and this number is increasing by 11% per year.

To Find :

An equation that can be used to find the number of people, y, in archery clubs across the city after 8 years.

Solution :

Increase in people after 1 years :

[tex]P = 260 + 260\times 0.11\\\\P = 260( 1 + 0.11)\\\\P = 260\times 1.11[/tex]

After 2 years :

[tex]P = 260\times 1.11 + 260\times 1.11\times 0.11\\\\P = 260\times 1.11 ( 1 + 0.11)\\\\P = 260\times 1.11^2[/tex]

Therefore, after 8 years the expression of population is :

[tex]P = 260\times 1.11^8[/tex]

Hence, this is the required solution.

Answer:

two

Step-by-step explanation:

In the case when there is a congruent rectangle so that represent the equal sides i.e. the width and the length would be the same.

Since it is mentioned that one rectangle JKLM has 4 inch and 7 inches dimension so there would be the possibility that the length of J M might be 4 or 7

So here the possibility of the length is two

There are two possible answers:

t = 2/3   or   t = -1/3

========================================================

Explanation:

The expression x+3 is the same as x-(-3). It is of the form x-k

Recall that by the remainder theorem, we know that p(x) is divisible by (x-k) if and only if p(k) = 0.

In this case, k = -3. Plug this into the p(x) function and we get

p(x) = t^2*x^3 - 3t*x + 6

p(-3) = t^2*(-3)^3 - 3t*(-3) + 6

p(-3) = -27t^2 + 9t + 6

Set that equal to 0

p(-3) = 0

-27t^2 + 9t + 6 = 0

-3(9t^2 - 3t - 2) = 0

9t^2 - 3t - 2 = 0

Now apply the quadratic formula to solve for t

[tex]t = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\t = \frac{-(-3)\pm\sqrt{(-3)^2-4(9)(-2)}}{2(9)}\\\\t = \frac{3\pm\sqrt{81}}{18}\\\\t = \frac{3\pm9}{18}\\\\t = \frac{3+9}{18}\ \text{ or } \ t = \frac{3-9}{18}\\\\t = \frac{12}{18}\ \text{ or } \ t = \frac{-6}{18}\\\\t = \frac{2}{3}\ \text{ or } \ t = -\frac{1}{3}\\\\[/tex]

We get two possible solutions for t.

Answer:

d.y=x/3+4

Step-by-step explanation:

we have

slope=(y-b)÷(x-a)

1/3=(y-2)÷(x--6)

(x+6)=3(y-2)

x+6=3y-6

x+6+6=3y

(x+12)÷3=y

y=x/3+4
