Need help on both problems.

Answer:

The 8th term is 23

Step-by-step explanation:

If you are given a formula for the sequence,

an = 2n+7

then substitute n=8 to find the 8th term.

a8 = 2(8) +7

a8 = 16+7

a8 = 23

Answer:

a8 = 23

Step-by-step explanation:

If you got 3 questions wrong, then you got 25-3 = 22 right. So that would be 22/25 = 0.88 = 88% questions correct

------------------------------

If you got 3 questions right out of 25, then 3/25 = 0.12 = 12% is the score you get. Note how 88% + 12% = 100%

The answer should be

x= -9

Answer:

x = -9

Step-by-step explanation:

1/3 (x+3) = 2/3x + 4

1/3x + 1 = 2/3x + 4

subtract 1/3x from both sides

1 = 2/3x - 1/3x +4

1 = 1/3x + 4

subtract 4 from both sides

1 -4 = 1/3x

-3 = 1/3x

multilply by 3 (to cancel out the 1/3)

-9 = x

x = -9

Answer:

About 0.12

Step-by-step explanation:

There are 3 people who prefer merchant D out of n = 25 total

Divide: 3/25 = 0.12

Optionally, you can multiply both top and bottom of 3/25 by the value 4 and it leads to 3/25 = 12/100 = 12% = 0.12

Answer: The answer is 46.5 inches to 49.5 inches.

Step-by-step explanation: We are to tell the height limits of a 7-year old child.

Various scientific experiment shows that the height of maximum 7-year old girl child lies between 46.5 inches and 49.4 inches and the height of maximum 7-year old boy child lies between 46.6 inches and 49.5 inches.

So, combining the height limits of girls and boys, we can say that the height limit of 95% 7-year old child lies between 46.5 inches and 49.5 inches.

Thus, the answer is 46.5 inches and 49.5 inches.

Answer:

The rover would travel 75.95 centimeters in 15 1/2 seconds.

Step-by-step explanation:

Simply multiply 4.9 by 15 1/2.

Hope it helps!

Answer:

75.95 cm

Step-by-step explanation:

We know that distance = rate  times time

d =rt

We know the rate = 4.9 cm/s

and time = 15 1/2 s = 15.5 s

Substituting these into d=rt

d = (4.9 cm/s) * 15.5 s = 75.95 cm

The endpoints of a triangle are called vertices and triangles are labeled by their vertices, e.g., triangle ABC. Conditions for congruent triangles include having congruent sides (SSS), congruent sides and included angle (SAS), and congruent angles with either the included or non-included side (ASA or AAS).

Endpoints of a Triangle and Conditions for Congruent Triangles

The endpoints of a triangle are called the vertices, and they are typically labeled with capital letters such as A, B, and C. When referring to a triangle by its vertices, it is commonly denoted as triangle ABC.

Two triangles are congruent if:
 
 Each pair of corresponding sides is congruent (SSS Congruence)

The conditions (a), (c), (d), and (e) from the student's options are correct descriptions of congruent triangles according to congruence theorems and postulates such as the Second Theorem of Congruence, ASA, SAS, and AAS Congruence. However, option (b) could potentially create ambiguity since it mentions two pairs of corresponding angles and a pair of corresponding sides, but does not specify the included side which is necessary for congruence based on ASA or AAS Congruence.

Answer:

y = 2x-16

Step-by-step explanation:

To find a line when we know the slope and a point, we can use the point slope formula for a line

y-y1 = m(x-x1)  

where the point is (x1,y1) and the slope is m.  Substituting the known information in.

y--8 = 2 (x-4)

y+8 = 2(x-4)

We can manipulate this into slope intercept form by distributing the 2

y+8 = 2x-8

and subtracting 8 from each side

y+8-8 = 2x-8-8

y = 2x-16

Answer:

50.4

Step-by-step explanation:

Answer:

Step-by-step explanation:

I assume you mean "if the ratio of 7 less than a number and 7 more than the number is 2".

Let x be the number.

Ratio is division.

(x-7)/(x+7)=2

Multiply by (x+7) on each side:

x-7=2(x+7) = 2x+14

Add 7 on each side

x=2x+21

Subtract 2

-x=21

x=-21

The equation for converting a Celsius temperature into a Fahrenheit one is given by the linear equation F = 1.8C + 32. The slope of this equation is 1.8 and the y-intercept is 32.

The subject of this question is Mathematics, specifically the study of linear equations. To find the slope and the y-intercept of the equation that transforms a Celsius temperature into a Fahrenheit one, we can use the two points you provided: (0, 32) and (100, 212). The slope can be calculated as follow: (212 - 32) ÷ (100 - 0) = 180 ÷ 100 = 1.8. The y-intercept is the Fahrenheit temperature when the Celsius temperature is zero, so it's 32. Therefore, the equation you are looking for in slope-intercept form is: F = 1.8C + 32, where F is the temperature in Fahrenheit and C is the temperature in Celsius.

Answer: b+2

Step-by-step explanation:

4b-7-3b+9

b+2

Simplifying:

3b + -9 + -8b = 11

Reorder the terms:

-9 + 3b + -8b = 11

Combine like terms: 3b + -8b = -5b

-9 + -5b = 11

Solving

-9 + -5b = 11

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '9' to each side of the equation.

-9 + 9 + -5b = 11 + 9

Combine like terms: -9 + 9 = 0

0 + -5b = 11 + 9

-5b = 11 + 9

Combine like terms: 11 + 9 = 20

-5b = 20

Divide each side by '-5'.

b = -4

Simplifying

Answer: b = -4

Answer:

975 bulbs

Step-by-step explanation:

1/40 bulbs were defective

That means 1-1/40 were not defective

40/40 - 1/40 = 39/40 were not defective

We have 1000 bulbs

Multiply the number of bulbs  by the fraction that is not defective to get the number of bulbs that should not be defective.

1000 * 39/40 = 975 bulbs

Answer:

aₙ = 4(-1)ⁿ⁻¹(3)ⁿ⁻¹

Step-by-step explanation:

The formula for the nth term of a geometric sequence is

aₙ = a₁rⁿ⁻¹

We can get the value for r by dividing aₙ by aₙ₋₁.

a₄/a₃ = -108/36

a₄/a₃ = -3

      r = -3

    aₙ = 4(-3)ⁿ⁻¹

aₙ = 4(-1)ⁿ⁻¹(3)ⁿ⁻¹

The (-1)ⁿ⁻¹ term makes even-numbered terms negative.

Answer:

D from A = 34 miles

Step-by-step explanation:

We know the total distance  is 200 miles  (this would be when they meet)

The rate for cyclist A is 17

The rate for cyclist B is 83

We know the time is equal

Distance = rate * time

Distance for A = 17t

Distance for B = 83 t

The total distance  =  distance for A + distance for B

200 = 17t + 83t

Combine like terms

200 = 100t

Divide each side by t

200/100 = 100t/100

They will meet at t =2 hours

I know you say we need the distance

Distance for A

D = 17*t

We now know t

D = 17*2

D = 34 miles

Answer:

Step-by-step explanation:

cyclist going 17 mph n motorcyclist going 83 mph opposite way

so their net closing speed=17+83=100mph

A n B 200 mi apart

so they will meet in 200/100=2hrs

at dat time, cyclist will be 2x17=34mi from pt A

Final answer:

Travis must deposit $27.85 to cover the $7.85 outstanding charge and the previous $20 overdraft fee, to avoid further overdraft fees and bring his account balance back to at least $0.

Explanation:

Travis needs to not only cover the outstanding charge to avoid further overdraft fees but also bring his account balance back to at least $0. If Travis currently has an outstanding charge of $7.85, and overdraft fees are typically $35 or higher, it's clear that merely covering the charge won't be enough; he must also compensate for any negative balance incurred from previous overdraft fees.

Assuming the $20 fee has already been applied to his account and his balance is now at -$20 (not considering any other transactions that have taken place), Travis would need to deposit enough money to cover both the fee and the outstanding charge. Therefore, he would need to deposit a total of $20 (to bring his balance to $0) plus the $7.85 outstanding charge, which sums up to $27.85. By depositing this amount, Travis would avoid a second overdraft fee and any additional monetary penalties.

It is worth noting that financial literacy is essential to manage personal finances effectively and avoid potential overdraft situations which could lead to a cycle of fees and negative balances.
