Answer:

102

Step-by-step explanation:

Nat had a total of 102 stamps which he divided into 17 sets. Each set contained six stamps.

To find out how many stamps Nat had, we need to multiply the number of sets by the number of stamps per set. Nat divided his stamps into sets of six. He made 17 sets. To calculate the total number of stamps, we perform the multiplication:

Multiply the number of stamps in each set (6) by the number of sets (17).

6 stamps/set × 17 sets = 102 stamps
Hence, Nat had 102 stamps in total.

Answer:

13

Step-by-step explanation:

Circumference=2πr

2πr=26π

2r=26

r=13

Final answer:

The radius of a bicycle wheel that travels 26π inches per revolution is found using the circumference formula. By solving 26π = 2πr, the radius is determined to be 13 inches.

Explanation:

The question asks to determine the radius of a bicycle wheel that travels 26π inches per revolution. To find the radius, we can use the formula for the circumference of a circle, which is C = 2πr, where C is the circumference and r is the radius. Since we know the wheel travels 26π inches for each revolution, this distance is the circumference of the wheel.

Setting up the equation 26π = 2πr, we can solve for the radius r by dividing both sides of the equation by 2π:

The radius of the bicycle wheel is 13 inches.

Answer:

The actual area of the page will be 120 square inches.

Step-by-step explanation:

Janice is creating a page of scrapbook having vertices (2,1), (7,1), (7,7), and (2,7).

If we plot the points on the coordinate plane then we will see that the page is of a rectangular shape with length (7 - 1) = 6 units which is parallel to the y-axis and width (7 - 2) = 5 units which is parallel to the x-axis.

So, the area of the page is (6 × 5) = 30 square units.

Now, given that 1 square unit is equivalent to 4 square inches.

Therefore, the actual area of the page will be (30 × 4) = 120 square inches. (Answer)

X =71. The reason is because the interior angles of a triangle add up to 180. 180-38=142. It is an isosceles triangle so the bottom two angles are equal. Divide 142/2 to get 71. ;)

Step-by-step explanation:

The total amount that Karen will be for the sweatshirt including tax will be $32.10.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Karen buys a sweatshirt for $30. The sales sold be tax in her state is 7%.

The total amount that Karen will be for the sweatshirt including tax will be calculated as,

Total cost = $30 x (1 + 7%)

Total cost = $30 x (1 + 0.07)

Total cost = $30 x (1.07)

Total cost = $32.10

The total amount that Karen will be for the sweatshirt including tax will be $32.10.

Answer:

(a) 4x=5(x-18)

(b) ∠A=∠B=360°

Step-by-step explanation:

Corresponding angles : when two lines are crossed by a transversal , the angle in matching corners are called corresponding angles.

Since the corresponding are congruent.

Therefore,

∠A=∠B

⇔4x=5(x-18)

⇔4x=5x-90

⇔4x-5x=-90

⇔-x=-90

⇔x=90

Therefore ∠A=∠B= 4×90°=360°

Answer:

t=100-2x

Step-by-step explanation:

The amount of water in the cup after t seconds can be represented by the linear function Y = 100 - 2t. This equation is derived from the initial amount of water in the cup and the rate at which water is being poured out.

The function that shows the amount of water in the cup after t seconds is a linear function. It can be represented as Y = 100 - 2t. In this equation, Y represents the amount of water left in the cup and t represents time in seconds.

This equation comes from the initial amount of water (100 milliliters) minus the rate of water being poured out of the cup (2 milliliters per second times the number of seconds). For example, after 3 seconds, the amount of water left would be 100 - 2*3 = 94 milliliters.

Answer:

By bike= 4 hours

By walk= 3 hours

Step-by-step explanation:

Given: Sydney travel by bike at 9 mph

           Sydney travel by walk at 7 mph.

           Total trip time= 7 hours

           Distance to bookstore= 57 miles.

Lets assume the time spent travelling by bike be "x".

∴ Time spent travelling by walk is [tex](7-x)[/tex]

Now, lets find the distance travelled on bike and by walk.

we know, [tex]Distance= speed\times time[/tex]

∴ Distance by bike= [tex]9\times x= 9x[/tex]

   Distance by walk= [tex]7\times (7-x)[/tex]

Using distributive property of multiplication.

∴ Distance by walk= [tex]49-7x[/tex]

Next, forming an equation for total distance travelled to find x.

⇒ [tex]9x+ (49-7x)= 57\ miles[/tex]

Opening parenthesis

⇒ [tex]9x+49-7x= 57[/tex]

⇒[tex]2x+49= 57[/tex]

Subtracting both side by 49

⇒[tex]2x= 8[/tex]

dividing both side by 2

⇒[tex]x= \frac{8}{2}[/tex]

∴[tex]x= 4\ hours[/tex]

Hence, time spent travelling on bike is 4 hours.

Subtituting the value x to find the time spent travelling by walk.

Times spent travelling by walk= [tex]7-4= 3\ hours[/tex]

hence, time spent travelling by walk= 3 hours

Answer:

x = 6

Step-by-step explanation:

x = 3 is the equation of a vertical line parallel to the y- axis.

The equation of a parallel line will therefore be a vertical line.

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (6, 1) with x- coordinate 6, thus

x = 6 ← equation of parallel line

Final answer:

The equation of the line that is parallel to x = 3 and passes through (6, 1) is x = 6.

Explanation:

The question relates to finding the equation of a line that is parallel to another line, specifically the line x = 3, and that also passes through a given point, namely (6, 1). Since the line x = 3 is a vertical line, any line parallel to it will also be vertical and have an equation of the form x = k, where 'k' is a constant.

In this case, the line we are looking for must go through the point (6, 1), which means it will have the same x-coordinate as this point. Therefore, the equation of the line is simply x = 6.

Answer:

The numbers are 15 and 6.

Step-by-step explanation:

We can solve the problem algebraically (using equations). First, write equations that represent the situation.

Choose variables to represent the numbers:

let the numbers be "x" and "y"

Take apart each section of the problem and make an equation.

"The sum of two numbers is 21"

x + y = 21             Sum means the answer when you add numbers

"Their difference is 9"

x - y = 9               Difference means the answer when you subtract numbers

Using the two equations, you can solve using elimination. With this method, you get rid of one of the variables, so you can easily solve for the other one. You can use elimination when one of your variables have the same variable number. Both equations have "1x" and "1y" ("1" is never written).

Add the equations together by adding normally, with each of the terms with the same variable.

.     x + y = 21             Add each term

+     x - y = 9            (x + x = 2x)     (y + (-y) = 0)     (21 + 9 = 30)

.   2x + 0 = 30         "y" variable cancelled out

.          2x = 30        

.       2x/2 = 30/2         Divide both sides by "2" to isolate "x"

.            x = 15         Answer for one number

To find the other number, substitute 'x' for 15 into one of the equations.

x + y = 21

15 + y = 21         Isolate "y" now

15 - 15 + y = 21 - 15         Subtract 15 from both sides

y = 21 - 15         15-15 cancelled out on the left side. Solve right side.

y = 6       Answer for second number

Therefore the two numbers are 15 and 6.

Final answer:

When 2 pizzas, each cut into 8 slices, are equally shared among 3 friends, each person would eat 5 and 1/3 slices of pizza.

Explanation:

The question involves dividing a certain number of pizza slices equally among friends. Initially, we have 2 pizzas and each pizza is cut into 8 slices, making a total of 16 slices. To find out how many slices each person ate when the amount is the same for everyone, we simply divide the total number of slices by the number of friends.

Since a pizza slice cannot be split into a third naturally, practically, each friend would eat 5 slices and a little bit more from another slice.
