Answer:

140.4ft^2

Step-by-step explanation:

since all four sides are equilateral triangles, you only need to find one triangle and multiply by 4.

area of triangle = 0.5×base×height = 0.5×7.8ft×9ft =35.1ft^2

surface area of pyramid= 35.2ft^2 × 4 = 140.4ft^2

Answer:

x=1

Step-by-step explanation:

y=x²-2x-8

First, we solve for the vertex

The equation for the vertex is -b/2a

Substitution:

-b/2a

=-(-2)/(2*1)

=2/2

=1

Therefore the equation for the line of symmetry is x=1

THIS ANSWER ISN'T MINE. I TOOK IT FROM AN ANSWER TO THE SAME QUESTION ANOTHER USER POSTED.

Answer:

33.8

Step-by-step explanation:

1) Use Phythagoras theorem to get RS ↓

[tex]9.1 ^{2} + 6 ^{2} = 118.81 \\ \sqrt{118.81 } = 10.9[/tex]

2) RS = RQ

therefore, to get the perimeter, you'll have to total up the sides of the triangle ↓

[tex]rs + rq +qt + ts \\ = 10.9 + 10.9 + 6 + 6 \\ = 33.8[/tex]

Answer:184 cm^2

Step-by-step explanation:

10*6*2=120

6*2*2=24

2*10*2=40

120+40+24=184

Answer:

184 cm²

Step-by-step explanation:

You can find the surface area of this net by finding the area of each rectangle and adding them up.

The top rectangle has dimensions of 10 and 6. You multiply them to get 60. Add in the units and the area of the top rectangle is 60 cm².

The rectangle under the one we just found the area for has the dimensions 10 and 2. Find the area. A = 20 cm².

The two rectangles to the side of the second rectangle have the dimensions of 6 and 2. The area of one is 12 cm². This means the two rectangles added together are 24 cm².

The next rectangle has the same dimensions as the first rectangle we solved. Therefore, the area is the same, which is 60 cm².

The last rectangle has the same dimensions as the second rectangle we solved. Therefore, the area is the same, which is 20 cm².

We will add the numbers altogether to find the surface area.

60 + 20 + 24 + 60 + 20 = 80 + 24 + 80 = 104 + 80 = 184 cm²

The dog walked 3 miles less in last week than this week.

An approximation is anything that is similar, but not exactly equal, to something else. A number can be approximated by rounding.

Given that, last week you walked your dog 12.405 miles. this week, you walked your dog 15 miles.

The dog walked in last week approx = 12 miles

The dog walked this week = 15 miles

The  fewer miles did he walked = 15-12 = 3

Hence, the dog walked 3 miles less.

Answer: 64mi^2

Step-by-step explanation:

(2*5) +(6*8)+((3*4)/2) = 64mi^2

Answer:

Radius:

radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.

Diameter:

2 times the radius is the circle's diameter.

Circumference:

The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.the formula for circumference of a circle is 2 x pi x r(radius).

Answer:

If the spinner has an even number of spaces,

8

. If the spinner has an odd number of spaces, more information is needed.

Explanation:

The answer depends on whether the spinner has an odd or even number of spaces.

If the spinner has an even number of numbers on it, there will be an equal number of odd and even numbers, meaning that the probability of spinning an odd number is

If the spinner has an odd number of numbers on it, the probability of spinning an odd number will vary. For instance, if there are 3 spaces on the spinner, the probability of spinning an odd number will be

2

. However, if there are 11 spaces, the probability will be

Step-by-step explanation:

The probability of tossing tails and spinning yellow is 1/6.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Outcomes of tossing a coin= {T,H}

Outcomes of spinner={ R,Y,B}

Now, outcomes are in the event "Toss a tails, spin yellow"

= {TY}

probability of tossing tails and spinning yellow,

Answer:

1,2,4,8,2

Step-by-step explanation:

For the first blank, it asks you to look at the change in y-value where the x-value changes from 0 to 1. As the y-value goes from 2 to 3 in this space, it is increasing by 1.

For the second blank, it asks you to look at the change in y-value where the x-value changes from 1 to 2. As the y-value goes from 3 to 5 in this space, it is increasing by 2.

For the third blank, it asks you to look at the change in y-value where the x-value changes from 2 to 3. As the y-value goes from 5 to 9 in this space, it is increasing by 4.

For the fourth blank, it asks you to look at the change in y-value where the x-value changes from 3 to 4. As the y-value goes from 9 to 17 in this space, it is increasing by 8.

For the fifth blank, it asks you to find the rate of change for the graph using the information we previously found. As you can see, the rate of change is 2 for this exponential function, as for every x-value increasing by 1, the change in y-value is multiplied by 2. In other words, if you look at the prior answers you can see that 1*2=2, 2*2=4, and 4*2=8, and all of these changes occur while the x-value increases consistently. Therefore, the grow factor is 2 for every interval of 1.

πr + 2r

Step-by-step explanation:

Perimeter of Semicircle

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius.

Step-by-step explanation:

1. d = 22mm

circumference = πr + d

= 22/7 × 11 + 22

= 56.57 mm

2. r = 4 inches

circumference = πr + d

= 22/7 × 4 + 8

= 20.57 Inches

3. d = 10 yards

circumference = πr+d

= 22/7 × 5 + 10
