Find the surface area of a square pyramid with side length 1 mi and slant height 4 mi.

Answer:

10 + 3x </= 30

x </= 6.666

He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.

Step-by-step explanation:

10 + 3x </= 30

10 is the minutes for the centerpiece

3 is the minutes to make each small crane

x is the number of small cranes he can make

he has less than or equal to 30 minutes to complete them.

10 + 3x </= 30

subtract 10 from both sides

3x </= 20

x </= 6.666

He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.

Answer:

160

Step-by-step explanation:

Using the distributive property, we can write:

5(32) = 5(30 + 2)

= 5(30) + 5(2)

= 150 + 10

= 160

Therefore, an expression equivalent to 5(32) using the distributive property is 160.

66 children go sailing on sunday.

Two or more expressions with an Equal sign is called as Equation.

Given,

The number of kids go on Holiday =120

The ratio of the number of girls to the number of boys is 3/5.

Number of girls = (3/5)×120 = 72 girls.

Then there are 48 boys

120-72=48

16/25 of the boys go climbing

16/25×48=30

Boys sailing, 48-30 = 18

Twice as many girls go sailing as go climbing

Then 2x+x=72

3x=72

x=24

Therefore 48 girls are sailing and 24 are climbing

Total kids sailing 48+18=66

Hence 66 kids go sailing on sunday.

Answer: 36 inches (in.)

Step-by-step explanation:

The first thing you need to do is form a right triangle from the starting point to the hole to the corner where the ball is at. Right triangles have a hypotenuse (the longest side), and two legs (the shorter sides).

We are told next to the drawing that it’s 39 feet from the staring point to the hole (given a straight line). This is the length of our hypotenuse. We are also given the length of one of the legs, with it being 36 feet.

We need to find the length of the last leg, the length from the ball to the hole. To do this, we can use the Pythagorean Theorem. The Pythagorean Theorem states that the square of each of the legs equals the square of the hypotenuse. The formula for the Pythagorean Theorem is \(a^{2} +b^{2} =c^{2}\), with \(a\) and \(b\) being the legs, and \(c\) representing the hypotenuse.

Input the given values into the formula and you get the following:

\(a^{2} +b^{2} =c^{2}\)
\(36^{2} + x^{2} =39^{2}\)

\(\sqrt{36^{2} } +\sqrt{x^2} =\sqrt{39^2}\)

\(36 +x =39\)

\(x=3\)

Therefore, the length from the ball to the hole is 3 feet (ft.).

BUT WAIT
The question asks us to provide our answer in inches (in.), and 1 foot equals 12 inches.

Therefore, the distance from the ball to the hole is 36 inches (in.).

Answer: 51

Step-by-step explanation:

Answer:

51

Step-by-step explanation:

26 + 3x + 1 = 180

27 + 3x = 180

3x = 180 - 27

3x = 153

x = 153 / 3

x = 51

Step-by-step explanation:

2.81 * 39.75 = 111.57 = 112

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

The sum of two consecutive number is 55'which is the largest number? So the numbers are 27 and 28.

Step-by-step explanation:

If we say \(x\) is the first number, then the next consecutive number will be \(x+1\).

Using this, we can make an equation.

\(x+(x+1)=55\)

\(2x+1=55\)

\(2x=54\)

\(x=27\)

And so we know that the two consecutive numbers are 27 and 28.

Answer:

Answer: . Area of figure = area of squane + anea

of tringle =side * side + 1/2 xbagex height =7 * 7+

1/2 * 7 *

Approximately 8.47 cm² of the figure is painted green

A square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is given as side².

We have,

To find the area painted green, we need to calculate the areas of the square and the triangle and then multiply by 14.2% (or 0.142).

The area of the square is simply the length of one side squared, so:

Area of square = (7 cm)² = 49 cm²

The area of the triangle is one-half the base times the height, so:

Area of triangle = (1/2)(7 cm)(3 cm) = 10.5 cm²

Therefore, the total area of the figure is the sum of the area of the square and the triangle:

Total area = 49 cm² + 10.5 cm² = 59.5 cm²

Finally, to find the area painted green, we multiply the total area by 14.2%:

Area painted green = 0.142 x 59.5 cm² ≈ 8.47 cm²

Therefore,

Approximately 8.47 cm² of the figure is painted green
