The given side lengths, 6 cm and 8 cm, satisfy the Pythagorean theorem because $6^2 + 8^2 = 100 = 10^2$, which means that the triangle is a right triangle.

To determine if there is more than one right triangle with whole-number side lengths that includes these given side lengths, we need to check if there exist other pairs of whole numbers that satisfy the Pythagorean theorem and include 6 cm and 8 cm as two of their sides.

Let's call the third side of the right triangle x. Then we have:

62+82=x26^2 + 8^2 = x^262+82=x2

which simplifies to:

36+64=x236 + 64 = x^236+64=x2

100=x2100 = x^2100=x2

x=100=10x = \sqrt{100} = 10x=100

​=10

So the only other possible triangle with whole-number side lengths that includes the given side lengths has side lengths of 6 cm, 8 cm, and 10 cm.

Therefore, there is only one other right triangle with whole-number side lengths that includes the given side lengths, and it is unique.

The amount of flour that will be needed for 38 cakes is 912 grams therefore Johan does not have enough amount of flour

A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation.

360 grams is needed for 15 small cakes

therefore for 1 small cake, 369/15 = 24grams will be needed

therefore for 38 small cakes = 38× 24 = 912 grams of flour will be needed.

Johan has 0.85 kg of flours which is equivalent to 0.85 × 1000grams = 850 grams of flour.

Since 912 grams will be needed for 38 small cakes , it shows that Johan does not have enough amount of flour for 38 small cakes.

Step-by-step explanation:

To find 0.007 divided by 0.498, we can perform the following calculation:

0.007 / 0.498 ≈ 0.0141

Rounding this to the nearest tenth gives:

0.0141 ≈ 0.0

Therefore, the result, rounded to the nearest tenth, is 0.0.

The perimeter of the square with side of 5 cm is 20 cm.

The perimeter of the square with side length of 15 cm is 60 cm.

The area of each square is calculated as follows;

Let the dimension of first square = x

Let the dimension of second square = y

x² + y² = 250 ---- (1)

4(x + y) = 80 ----- (2)

x + y = 80/4

x + y = 20

x = 20 - y

Substitute x in equation (1)

(20 - y)² + y² = 250

400 - 40y + y² + y² = 250

2y² - 40y + 150 = 0

y² - 20y + 75 = 0

solve for y, using formula method;

y = 15 or 5

Solve for x;

x = 20 -15 = 5 or

x = 20 - 5 = 15

Step-by-step explanation:

A linear function is a function where we have a constant rate of change.

The equation of a linear function is

[tex]y = mx + b[/tex]

where m is the slope (change in y/change in x)

and b is the y intercept.

Note: Sometimes our variables will different names, but

Slope is just change in dependent variable/change in independent variable.

A linear function has a constant slope throughout.

In this problem,

t is the independent variable

W is the dependent variable

So our point will. be

(t,W)

where t is number of weeks after planted

and W is weight

So the slope would be

Change in W/Change in t.

We know at 3 weeks, the pumpkin weighed 141

So this point is

(3,141)

We know 7 weeks, later, the pumpkin weighed 372 so

(10,372)

A. The weight the pumpkin gain each week is our slope so

[tex] \frac{372 - 141}{7} [/tex]

[tex] \frac{231}{7} = 33[/tex]

So the pumpkin gained 33 pounds each week.

Part 2: Is in slope intercept form,

and we know the slope,33,

[tex]w = 33t + b[/tex]

We don't know what b is.

Let plug in a coordinate pair, and solve for b.

Let's use (3,141)

[tex]141 = 33(3) + b[/tex]

[tex]141 = 99 + b[/tex]

[tex]42 = b[/tex]

So our equation is

[tex]w = 33t + 42[/tex]

Hope this helps

The weight that the pumpkin gained per week can be found to be 33 pounds.

The equation to show the relationship between pumpkin weight and elapsed time is W = 33 t + 42

The weight gained by the pumpkin per week can be found by the formula :

= (Weight gained after 7 more weeks - Weight after 3 weeks ) / 7 weeks

= ( 372 - 141 ) / 4

= 33 pounds

This means the original weight of the pumpkin was:
= 141 - ( 33 x 3 weeks )
= 42 pounds

The equation to show the relationship between pumpkin growth and weeks is therefore:

W = Growth per week x Number of weeks + original weight

W = 33 x + 42

The solution is x = 12

Let x be the number you thought of at the beginning. Following the steps:

Multiply by 2: 2x

Add 8: 2x + 8

Divide by 4: (2x + 8) / 4

Subtract 3: (2x + 8) / 4 - 3

The final answer is seven less than the number you thought of at the beginning: (2x + 8) / 4 - 3 = x - 7

The equation is: (2x + 8) / 4 - 3 = x - 7

2. (2x + 8) / 4 - 3 = x - 7

(1/2)x + 2 - 3 = x - 7

(1/2)x - 1 = x - 7

To graph the inequality 9x + 5y > 1, we first need to graph the equation 9x + 5y = 1, which is the equation of the line that separates the two regions determined by the inequality.

To graph this line, we can solve for y in terms of x:

9x + 5y = 1

y = (-9/5)x + 1/5

This is the equation of a line with slope -9/5 and y-intercept 1/5. We can plot this line on a coordinated plane. Since the slope of the line is negative, the shading should occur above the line, which means the correct answer is: The shading would occur above the solid line of the slope.

ANSWER: $1090

STEP 1:

The volume of one brick is given by multiplying its length, width, and height:

V = (7 1/4) in x 3 in x (2 1/4) in

V = (29/4) in x 3 in x (9/4) in

V = 2187/16 cubic inches

STEP 2:

The cost of one brick is given by multiplying the volume by the cost per cubic inch:

C = (2187/16 cubic inches) x $0.05/in^3

C = $1.09/brick

STEP 3: To find the cost of 1000 bricks, we simply multiply the cost of one brick by 1000:

Cost of 1000 bricks = 1000 x $1.09/brick

Cost of 1000 bricks = $1090

Therefore, the cost of 1000 bricks is $1090, rounded to the nearest cent.

There are 70 grandparents, 140 parents, and 190 children in attendance at the family reunion

Given data ,

Let's denote the number of grandparents as "g", the number of parents as "p", and the number of children as "c".

Given that there were 400 people total at the family reunion, we can write the equation:

g + p + c = 400

Now , there were twice as many parents as grandparents, so we can write:

p = 2g

And we are given that there were 50 more children than parents, so we can write:

c = p + 50

Now we can use the equations (1), (2), and (3) to solve for the values of g, p, and c.

On simplifying the equation , we get

g + 2g + (2g + 50) = 400

5g + 50 = 400

5g = 400 - 50

5g = 350

g = 350 / 5

g = 70

Now we can substitute the value of g into (2) to find the value of p:

p = 2g = 2 x 70 = 140

And we can substitute the value of p into (3) to find the value of c:

c = p + 50 = 140 + 50 = 190

Hence , there were 70 grandparents, 140 parents, and 190 children in attendance at the family reunion

In this case, each point in triangle ABC will be multiplied by a scale factor of 3, with point D as the center of dilation.

To dilate the triangle by a scale factor of 3, you can follow these steps

Hence,  if the scale factor is greater than 1, the dilated figure will be larger than the original. If the scale factor is between 0 and 1, the dilated figure will be smaller than the original. If the scale factor is negative, the figure will be reflected across the center of dilation.
