Answer:

$17.51

Step-by-step explanation:

3.40(1) = 3.40 - the (1) represents how many pounds you are buying.

3.40 (5.15) = 17.51

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:

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

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

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:

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.

The simple answer: 48

Step-by-step explanation:

Finding the area of a triangle in most cases is simple, multiply the two sides that are not the hypotenuse (the noticeably longer side) then divide the product by two. In this case the perimeter is included because you are given one side and the hypotenuse. With simple 12+14=26 and 34-26=8 you have the other side you need. So 12 times eight equals 96 divide that by two and you have the answer 48.

Answer:

Answer:

The slope of the given linear function is -4.

Step-by-step explanation:

We have been given the linear equation [tex]y=-4x-9[/tex]

The slope intercept form of a line is given by [tex]y=mx+b[/tex]

Here, b is y-intercept and m is the slope.

On comparing, the given equation with the slope intercept form, we get

b = -9

m = -4

It means that the y-intercept is -9 and the slope of the line is -4.

Therefore, the slope of the given linear function is -4.

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: Woops I meant 2 cannot be repeated because x-values cannot be the same. So it is C.

A function CAN have the same y-values such as (3,4) and (6,4). But a function CANNOT have the same x-values like (7,10) and (7,1) because it would be a straight line.

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:There is an app that helps you with this stuff.  

Step-by-step explanation:

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.

OK, so this is assuming we are considering that the first three kids to solve ARE NOT in the first day.

So we have 3 kids and it doubles

Day 1 : 6

Day 2 : 12

Day 3 : 24

Day 4 : 48

Day 5 : 96

Day 6 : 192

Day 7: 384

So it should take 7 days or a week to solve all the problems.

The equation:

(3 * 2)^x = 384

Answer:

It will take 7 days for all the class to complete the problems.

Step-by-step explanation:

We are given that 3 students solve math problems everyday.

Also, the number of students doubles each day.

So, we get the pattern,

Days (S)                             Number of students                      

1                                                     3                                                 =  3

2                                                    3 × 2                                           =  3 × 2¹  

3                                                    3 × 2 × 2                                     =  3 × 2²

4                                                    3 × 2 × 2 × 2                               =  3 × 2³

5                                                    3 × 2 × 2 × 2 × 2                         =  3 × 2⁴

6                                                    3 × 2 × 2 × 2 × 2 × 2                   =  3 × 2⁵

As, there are total 384 students in the class.

We get the equation as, [tex]3(2)^S=384[/tex]

On solving, we have,

[tex]3(2)^S=384[/tex]

i.e. [tex]2^S=\frac{384}{3}[/tex]

i.e. [tex]2^S=128[/tex]

i.e. [tex]S\log 2=\log 128[/tex]

i.e. [tex]S\times 0.301=2.107[/tex]

i.e. [tex]S=\frac{2.107}{0.301}[/tex]  

i.e. S = 7

Hence, it will take 7 days for all the class to complete the problems.

The jaguar will run 32 miles farther than the giraffe after both run for 4 hours, calculated using the equation: Distance = Speed x Time.

To calculate how much farther the jaguar will run compared to the giraffe, we can start by writing an equation for the distance each animal travels. Distance is equal to speed multiplied by time, which can be expressed as:

D = s *t

For the jaguar traveling at 40 miles per hour for 4 hours, the distance would be:

D_jaguar = 40 miles/hour*4 hours = 160 miles

For the giraffe traveling at 32 miles per hour for 4 hours, the distance would be:

D_giraffe = 32 miles/hour *4 hours = 128 miles

To find out how much farther the jaguar runs, subtract the distance run by the giraffe from the distance run by the jaguar:

Additional distance = D_jaguar - D_giraffe = 160 miles - 128 miles = 32 miles

The jaguar will run 32 miles farther than the giraffe.
