Does anyone know the answer to this question? Or at least a way to solve it?

Can u tell me what math book this was from ?

Step-by-step explanation:

As in the first four terms, I assume that means using the equation with 1,2,3,4.

11) if n = 1, the answer would be 3.

If n = 2, the answer would be 10.

If n = 3, the answer would be 17.

If n = 4, the answer would be 24.

12) If n = 1, the answer would be 55.

If n = 2, the answer would be 45.

If n = 3, the answer would be 35.

If n = 4, the answer would be 25.

An explicit formula is used to find any term in a sequence by putting in the number of that term in place of the unknown variable.

In order to find the first four terms, we need to plug values, from 1-4, separately in each of the formulas.

For f(n) = 7(n+1) - 11, put values from 1-4 in place of n:

f(1) = 7(1+1) - 11 = 3 ----> First term

f(2) = 7(2+1) - 11 = 10 ----> Second term

f(3) = 7(3+1) - 11 = 17 ----> Third term

f(4) = 7(4+1) - 11 = 24 ----> Fourth term

For f(n) = 65 - 10n, put values from 1-4 in place of n:

f(1) = 65 - 10(1) = 55 ----> First term

f(2) = 65 - 10(2) = 45 ----> Second term

f(3) = 65 - 10(3) = 35 ----> Third term

f(4) = 65 - 10(4) = 25 ----> Fourth term

Answer:

As given, measure of angle 4 is 70°

Then what would be the measure of ∠8.

Following cases comes into consideration  

1. If ∠4 and ∠8 are supplementary angles i.e lie on same side of Transversal, then

 ∠4 + ∠8=180°

⇒70°+∠8=180°  [∠4=70°]

⇒∠8=180°-70°

⇒∠8=110°

2nd possibility

But if these two angles i.e ∠4 and ∠8 forms a linear pair.Then

⇒ ∠4 + ∠8=180°

⇒70°+∠8=180°  [∠4=70°]

⇒∠8=180°-70°

⇒∠8=110°

3rd possibility

If ∠4 and ∠8 are alternate exterior angles.

then, ∠4 = ∠8=70°

4th possibility

If If ∠4 and ∠8 are corresponding angles.

then, ∠4 = ∠8=70°

Out of four options given Option A[ 110° because ∠4 and ∠8 are supplementary angles], Option B[70° because ∠4 and ∠8 are alternate exterior angles.] and Option D[70° because ∠4 and ∠8 are corresponding angles.] are Correct.

250 and 120 both adds up to 370 but 350 of the male play sports. So u answer can't be sloved

One hundred male athletes in the school play baseball only. This is determined by subtracting the number of males who play both sports and who play only basketball from the total number of male athletes.

The question states there are 350 male athletes in total at the high school. We know that 250 males play basketball and that 120 males play both sports. To figure out the amount of males who play baseball, we first subtract the number of males who play basketball and both sports from the total number of male athletes.

Therefore, the calculation would be as follows:

So, there are 100 males that only play baseball according to the given information.

Final answer:

Yes, a semi-regular tessellation can be created using squares and regular hexagons. One example of this is the honeycomb pattern, which consists of hexagons surrounded by squares.

Explanation:

Yes, it is possible to create a semi-regular tessellation using only squares and regular hexagons. A semi-regular tessellation is a pattern that repeats using two or more regular polygons, but with different arrangements around each vertex.

One example of a semi-regular tessellation using squares and regular hexagons is the honeycomb pattern. In this pattern, the squares and hexagons are arranged in such a way that they fill the plane without any gaps or overlaps.

To create the honeycomb pattern, you start by placing a regular hexagon in the center. Then, surround the hexagon with six squares, with each square touching two sides of the hexagon. Finally, place a hexagon on each side of the square, with each hexagon touching two sides of the square and one side of the adjacent hexagon. Repeat this pattern to create a tessellation.

Step-by-step explanation:

Answer:

Using definition of midpoint, Q is the mid point of PR.

Step-by-step explanation:

Given 2PQ=PR

And Q lies on the line PR (It should be given in the problem itself else we have to assume it to prove "Q is the midpoint of PR").

Then PR=PQ+QR using segment addition postulate.

Let us plugin PR in given equation.

2PQ=PQ+QR

Subtract PQ from both sides.

2PQ-PQ=PQ+QR-PQ

PQ=QR

Since Q lies on the line PR and PQ=QR, Q is the mid point of PR.

Hence proved.

In geometry, if 2PQ=PR, point Q is the midpoint of PR. This is because the given condition implies that the length of segment PQ is half of the length of the whole segment PR, meaning Q divides PR into two segments of equal lengths.

In Geometry, the statement 2PQ=PR is the given condition. Prior to your question, we are assuming that PQ and QR are line segments. This would imply that P, Q, and R all lie on the same line, with P and R being the endpoints and Q somewhere between them.

Now, the provided condition (2PQ=PR) means that the length of segment PQ is half of the length of the whole segment PR. If we assume segment PQ is 'a' units long, then 2PQ would be '2a' units long. According to the equation, PR is also '2a' units long.

By definition, the midpoint of a line segment is the point that divides the segment into two segments of equal length. Since PQ is half of PR, point Q would divide PR into two equal segments, PQ and QR, both being 'a' units in length. Therefore, Q is the midpoint of PR.

Answer: [tex]-\frac{3}{5}[/tex]

Step-by-step explanation:

If you solve for y, then it will be in y = mx + b format where m is the slope.

3x + 5y = 29

-3x           -3x

       5y = -3x + 29

       [tex]\frac{5y}{5} = \frac{-3x}{5} + \frac{29}{5}[/tex]

       [tex]y = \frac{-3}{5}x + \frac{29}{5}[/tex]

m = [tex]-\frac{3}{5}[/tex]

To find the slope of the line for the equation 3x+5y=29, rewrite it in slope-intercept form y=mx+b. After isolating y, you'll find that the slope m is -3/5.

To find the slope of the line represented by the equation 3x + 5y = 29, we need to rewrite the equation in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

First, we solve for y:

Now, the equation is in slope-intercept form, and we can easily identify the slope as -3/5. This means there is a decrease of 3 on the vertical axis for every increase of 5 on the horizontal axis. Thus, the slope of the line is -3/5.

Prime numbers mean that their factors are only the number itself and 1.

2, 3, 5, 7, 11, etc. all fall under this category.

note however, that the numbers have to be less than 8: [2, 3, 5, 7] are your choices

2 + 3 = 5

5 + 5 = 10

10 + 7 = 17

Therefore, {2, 3, 5, 7} are your answers

Combine the like terms (8y and 13y) in the given algebraic expression (8y - 5x + 13y), which equals 21y. Thus, after simplifying, the equivalent expression is 21y - 5x.

The given expression is 8y - 5x + 13y. In order to simplify it, combine the like terms. The like terms here are 8y and 13y because they both include the variable 'y'. By adding 8y and 13y, we get 21y. Thus, the simplified version of the given expression is 21y - 5x. So, the correct answer is Option A: 21y - 5x.

Answer:

[tex]44\ gallons[/tex]

Step-by-step explanation:

we know that

A fish tank holds [tex]80[/tex] gallons of water

so

By proportion

Find how many gallons represent [tex]55\%[/tex] of the total tank capacity.

[tex]\frac{80}{100}\frac{gallons}{\%} = \frac{x}{55}\frac{gallons}{\%}\\ \\x=55*80/100\\x= 44\ gallons[/tex]

There are 44 gallons of water in the tank. This is calculated by converting the percentage full into a decimal (0.55) and multiplying it by the total capacity of the tank (80 gallons).

The question is asking how many gallons are currently in the fish tank that is 55% full and has a total capacity of 80 gallons.

First, you need to convert the percentage of the tank that is full (55%) to a decimal. To do this, you divide the percentage by 100.

So, 55 divided by 100 equals 0.55.

Next, you multiply this decimal by the total capacity of the tank to find out how many gallons are currently in the tank. 0.55 times 80 equals 44. Therefore, there are 44 gallons of water in the fish tank now.
