Answer:

x = 29

Step-by-step explanation:

Take the smallest integer as x. The next one as (x+1) and the last one as (x+2)

x + (x+1) + (x+2) = 90

x + x + x + 3 = 90

3x = 87

x = 29

Hence, x = 29

Answer:

3

Step-by-step explanation:

Using Pythagoras formula

h^2 = (root under) p^2 +b^2

or, h^2= 20^2 + 21^2

or, h^2= 400+441

or, h^2= 841

or, h= (root under) 841

Therefore h= 29

Now,

Perimeter of a triangle= a+b+c

= 20+21+29

The dot plot with the least variability will be C.

Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing we did.

Thus, suppose if we observed the value 'x', then we will make a dot above 'x'. If there is already a dot over 'x', then we will make a new dot over that dot.

The dot plot with the least variability will be C.

Part A

I'm assuming you want the area of a circle with radius 17 yards.

We'll use the formula below

A = pi*r^2

A = (22/7)*17^2

A = (22*17^2)/7

A = 6358/7

A = 908  2/7

The sprinkler covers an area of about 908  2/7 square yards.

You'll type 908 in the left-most box

Then for the other two boxes, you'll have 2 up top and 7 down below to represent the fraction 2/7

The number 908  2/7 is a mixed number.

=======================================================

Part B

You mentioned that the radius reduces to 11 yards here. We'll use the same formula as above and pi = 22/7 approximately

A = pi*r^2

A = (22/7)*11^2

A = (22*11^2)/7

A = 2662/7

A = 380  2/7

The sprinklers can water an area of about  380  2/7  square yards.

This value is also a mixed number

380 is the value in the left most box (it's the whole part)

The other two boxes are filled out the same exact way as the previous part above.

Answer:

vertex = (4, - 37 )

Step-by-step explanation:

the equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

f(x) = 2x² - 16x - 5 ← factor 2 out of the first 2 terms

    = 2(x² - 8x) - 5

using the method of completing the square

add/subtract ( half the coefficient of the x- term )² to x² - 8x

f(x) = 2(x² + 2(- 4)x + 16 - 16) - 5

    = 2(x - 4)² - 32 - 5

   = 2(x - 4)² - 37 ← in vertex form

with vertex = (4, - 37 )

Answer:

a=108;b=36;c=72

Step-by-step explanation:

Answer:

a = 108°

b = 36°

c = 72°

Step-by-step explanation:

Note : the sum of the interior angles of a regular pentagon = 540°

Then

The measure of one interior angle of a reg pentagon =540/5 = 108°

Therefore a = 108°

c = 180 - 108 = 72°

SRT is a new isosceles triangle then :

[tex]b=\frac{180-108}{2} = \frac{72}{2} =36[/tex]

Step-by-step explanation:

Answer:

about 2/5 of the question probability lol

Assuming that L and d are known numbers, we can write.

[tex]W = \frac{49d + 91}{L}[/tex]

Remember that for a rectangle of width W and length L, the area is given by:

A = L*W

In this case, the area is 49d + 91, and the length is a known number, so we know the value of L.

Then we can write:

A = L*W =  49d + 91

To get the value of W, we need to isolate it on one side of the equation.

We can do that by dividing both sides by L.

[tex]W = \frac{49d + 91}{L}[/tex]

We assume that d and L are known, so with the above rational expression, we have W totally determined.

Answer:

in particular, the relationship between height of stack and number of cups yields a non-whole number of cups, corresponding to a height of 95 cm. In this context, that is not possible because we do not allow for parts of cups.

Step-by-step explanation:

It is possible for a stack of cups to be 95 cm tall depends on the size and shape of the cups and how they are stacked.

The area of Rectangle is length times of width.

Assuming the cups are all the same size and shape, the height of the stack would depend on the number of cups in the stack.

if each cup is 5 cm tall, a stack of 19 cups would be 95 cm tall (19 x 5 = 95).

If the cups are irregularly shaped or have varying sizes, it may be more difficult to stack them in a way that reaches 95 cm in height.

It is possible for a stack of cups to be 95 cm tall depends on the size and shape of the cups and how they are stacked.

It is possible for some stacks of cups to reach this height, but not necessarily all stacks of cups.

Hence, it is possible for a stack of cups to be 95 cm tall depends on the size and shape of the cups and how they are stacked.

Answer:

y = 7.5[tex]\sqrt{x}[/tex]

Step-by-step explanation:

given y is directly proportional to [tex]\sqrt{x}[/tex] then the equation relating them is

y = k[tex]\sqrt{x}[/tex] ← k is the constant of proportion

to find k use the condition y = 75 , x = 100 , then

75 = k[tex]\sqrt{100}[/tex] = 10k ( divide both sides by 10 )

7.5 = k

y = 7.5[tex]\sqrt{x}[/tex] ← equation of proportion

The base of the given triangle is calculated as: 16 ft

The formula that is used to calculate the area of a triangle is expressed as:

Area of triangle= ½ × base × height

We are given that:

Area = 32 ft²

Height = 4 ft

Thus:

32 = ½ × base × 4

32 = 2 * base

base = 32/2

base = 16 ft
