Step-by-step explanation:

24 + 1

The value of 8th term of the sequence will be 25.

The nth term of a sequence is given by T = a+ (n-1) d, here a is the first term and d is the common difference.

The nth term of the sequence is 3n+1

The 8th term will be 3 * 8 + 1 = 25

Therefore, the value of 8th term of the sequence will be 25.

Answer:

d) 3 1/4

Step-by-step explanation:

The equation for the total distance traveled per day is  1/4 ÷ 3 = 1/12 of the total distance

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total distance traveled per day be represented as A

Now , the equation will be

The distance traveled for the last 3 days = 1/4 of the total distance

So ,

Total distance traveled per day = distance traveled for the last 3 days / 3

Substituting the values in the equation , we get

Total distance traveled per day A = ( 1/4 ) / 3

On simplifying the equation , we get

Total distance traveled per day A = 1/12 of the total distance

Hence , the equation is 1/4 ÷ 3 = 1/12

Answer:

$325

Step-by-step explanation:

Let x be the cost of the bench.

Therefore, x + (x-96)=554

2x-96=554

2x=650

x=325

Answer:

The bench cost $229 and the garden table costs 229 + 96 = $325

Step-by-step explanation:

let the cost of the bench = x

the cost of the garden table = x + 96

x + (x + 96) = 554

2x + 96 = 554

2x = 458

x = 229

Taking into account the definition of probability, the correct option is option A.: The probability that the child has a  speaking part is [tex]\frac{2}{5}[/tex].

There are 20 children in the cast of a class play, and 8 of the children are boys. Then,   realizing the difference between the number of children and the number of boys you get that 12 of the children are girls.

On the other side, of the boys, 4 have a speaking part in the play, and of the girls, 8  do not have a speaking part in the play. Then, calculating the difference between the number of girls there are and the number of them that they do not have a speaking part in the play is obtained: 12 girls - 8= 4 girls. So, of the girls, 4  do not have a speaking part in the play.

Therefore, 4 + 4 = 8 of the children have a speaking part.

Probability is the greater or lesser possibility of a certain event occurring. In other words, probability establishes a relationship between the number of favorable events and the total number of possible events. Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.

[tex]P(A)=\frac{number of favorable cases}{number of possible cases}[/tex]

In this case:

Replacing in the definition of probability:

[tex]P(A)= \frac{8}{20}[/tex]

Simplifying the fraction:

[tex]P(A)= \frac{2}{5}[/tex]

Then, the correct option is option A.: The probability that the child has a  speaking part is [tex]\frac{2}{5}[/tex].

Answer:

49°

Step-by-step explanation:

Lines k and n seem to be parallel, so that means that 7x = 2x + 35 (corresponding angles are congruent), and x = 7. That means that angle A = 2x + 35 = 14 + 35 = 49° (because they are vertical angles).

The measure of <A is 49 degree.

Answer:

0.42* 1265=x

Step-by-step explanation:

There are 1265 students in Cypress Middle School. So we already know one part of the equation. 42% of these students are in PE. So we know that 42% of  these 1265 students are in PE. Of these means you probably have to multiply 42% and 1265. 42% = 0.42. So to write an equation we take the 0.42 and 1265 and put it together. Therefore, 0.42 times 1265=x.

Answer:

C. 30-60-90

Step-by-step explanation:

the ratio for a 3-6-9 triangle is x, 2x, x√3

if x=8, then 2x=16, and x√3 =8√3

it's not A because it is a right angle triangle.

it's not B because the ratio for an isoceles triangle is x:x:x√2. since a and b are not the same value, it can be assumed that it is not the answer

Answer:

c

Step-by-step explanation:

The longest side is hypotenuse.

Using Pythagorean theorem:

c² = a² + b²

16² = 8² + (8√3)²

256 = 256 True, so it is a right triangle.

Short leg = 8, long leg = 8√3

For 30-60-90 right triangle:

short leg = hypotenuse/2 = 16/2 = 8 , true:

long leg = short leg*√3 = 8√3, true.

Answer:

x = 38

Step-by-step explanation:

A straight line is 180°. We are given 134 and 84. We can find the value of ∠QLM and ∠QML by taking the given numbers and subtract it from 180:

180 - 134 = 46

180 - 84 = 96

All triangles add up to 180. And we already have two of the angles in the triangle. So to find x, we take 46 and 96, add, and subtract from 180:

46 + 96 = 142

180 - 142 = 38

Answer:

x = 38

Step-by-step explanation:

∠ KLO and ∠ MLO are adjacent and supplementary, thus

∠ MLO = 180° - 134° = 46°

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ NMO is an external angle of the triangle, thus

x + 46 = 84 ( subtract 46 from both sides )

x = 38

Step-by-step explanation:

The correct option is Option C: the point (24,8) shows different ratios of gallons of water and plants from other points.

The ratio is the representation of the fraction where this fraction is represented by the : symbol.

Given in the question number of plants that he watered every day is represented on the x-axis in the coordinate grid.

The number of gallons that he waters every day is represented on the y-axis in the coordinate grid.

We have to check the ratio of the y coordinate and the x coordinate is different from other options.

By checking all the options

Option A: (16,4) ratio of gallons of water and plants that are watered is 4/16= 1/4= 1:4

Option B: (8,2) ratio of gallons of water and plants that are watered is 2/8= 1/4= 1:4

Option C: (24,8) ratio of gallons of water and plants that are watered is 8/24= 1/3= 1:3

Option D: (48,12) ratio of gallons of water and plants that are watered is 12/48= 1/4= 1:4

By analyzing all options, Option A, B, D has a ratio 1:4. and Option C has a ratio 1:3.

Therefore the correct option is Option C: the point (24,8) shows different ratios of gallons of water and plants from other points.
