Answer:

Yes. For the triangles to be similar, all of the sides have to be proportionate to its corresponding side. If the ratio of one of the pairs sides of the triangles is 1:1, then all of the pairs of sides on the triangles have to also have a ratio of 1:1. Using this, according to SSS postulate, the two triangles are similar. With the given information, either both triangles are congruent, or they are not similar.

Answer:

y=2/7x+19/7

Step-by-step explanation:

Slope = m = (y₂-y₁)/(x₂-x₁) = (5-3)/(8-1) = 2/7

Therefore, our equation so far is y=2/7x+b where we can calculate b, the y-intercept by plugging in one of our given points [I used (1,3)]:

y=2/7x+b

3=2/7(1)+b

3=2/7+b

21/7=2/7+b

19/7=b

Therefore, our final equation is y=2/7x+19/7

The most reasonable prediction of the height of fifth-grade students is 55.

Mean is an average of values of a set. Arithmetic mean, geometric mean and harmonic mean are the type of mean.

Given that,

Height of 10 students in 5th grade are 57, 54, 59, 53, 56, 54, 51, 56, 54, 56.

To determine the height of 5th grade students,

find average of all the data,

average = total height of students / total number of students

              = (57 + 54 + 59 + 53 + 56 + 54 + 51 + 56 + 54 + 56) / 10

              = 550 / 10

              = 55

The most reasonable prediction of the height of fifth-grade students is 55.

Step-by-step explanation:

Answer:

(3,2)

Step-by-step explanation:

5x+2y= 19

4x - 3y = 6

I will use elimination

Multiply the first equation by 4

20x +8y = 76

Multiply the second equation by -5

-20x +15y = -30

Add them together to eliminate x

20x +8y = 76

-20x +15y = -30

---------------------------

       23y = 46

Divide by 23

23y/23 = 46/23

y =2

Now find x

5x+2y =19

Substitute y=2

5x+2(2) =19

5x+4 = 19

Subtract 4 from each side

5x +4-4 =19-4

5x= 15

Divide by 5

5x/5 = 15/5

x=3

x=-1, y=1

Step-by-step explanation:

Answer:

( -1, 1 )

Step-by-step explanation:

To solve, graph the equations and find the point of intersection.

when graphed these equations intersect at (-1, 1)

To double-check and make sure it's correct, plug in a solve.

x = -1

y = 1

y = 2(-1) + 3

1 = 2(-1) + 3

1 = -2 + 3

1 = 1

y = x + 2

1 = (-1) + 2

1 = 1

Answer and Step-by-step explanation:

As we can see by the given figure, we can cut out 2 rectangular prisms from this shape.

This gives us an easier time to find the volume. We will be using the volume formula for rectangular prisms: Length × Width × Height

The first prism has side lengths of:

Height = 6

Length = 11

Width = 7 (from the two 2's and the one 3 added together -- 2 + 2 + 3 = 7)

Let's multiply these values together.

6 × 11 × 7 =

66 × 7 =

462 -- First volume

The second prism has side lengths:

Height: 6

Length: 9

Width: 3

Let's multiply these values together.

3 × 6 × 9 =

3 × 56 =

168 -- Second volume

Now, we add together the volumes to get the volume of the composite figure.

168 + 462 = 630

The volume of the composite figure is 630 cubic feet.

The key features needed are the slopes and y-intercepts. If the slope and the y-intercept are the same then there are infinite amounts of intersections. If the slope is the same and the y-intercept is different then they will never intercept. Of the slope and the y-intercept are different, then they will intersect at one point.

Answer:

cos(A) = 12/13

Step-by-step explanation:

There are several ways to remember trigonometric functions, but my personal favorite is:

SOH - CAH - TOA

Where Sin(angle) = Opposite/Hypotenuse

Cos(angle) = Adjacent/Hypotenuse

and Tan(angle) = Opposite/Adjacent

The opposite is the side of a triangle that does not form part of the angle. E.g. for angle A the opposite is 5, for angle B the opposite is 12.

The hypotenuse is the longest side of the triangle, or the opposite in relation to the right angle (signified here by the little red box in the bottom left).

The adjacent is the side that isn't the hypotenuse, but is still next to a given angle. E.g. the adjacent for angle A is 12, and the adjacent for angle B is 5.

The cosine of angle A is the adjacent of angle A divided by the hypotenuse. The side adjacent to A is 12, and the hypotenuse is 13. Therefore, the cosine of angle A is 12/13.

A= 28.27 ft²

Step-by-step explanation:

if its trying to find area for a circle then we use the formula A=πr²

A=π(3)²

A= 28.27 ft²

Answer:

the answer is 18.85ft

Step-by-step explanation:

the question is asking you to find the circumfrance (the outside of the circle) so the formula you would use is:

C = 2πr

input the values you have into the formula

C= 2 x π x 3

(the radius is the distance between the very centre of the circle to the outside. it gives you the diameter which is the distance all the way across the circle so just half the diameter, which gives you a radius of 3)

put that into your calculator and youll get the answer

C= 18.8495559215

(i rounded the answer to two decimal places = 18.85ft)

Answer:

530.66 m²

Step-by-step explanation:

Area of circle= π×radius²

So the radius is 26/2= 13

13×13=169

So 3.14×169 would be the area

3.14×169= 530.66

(And if you have to round to the nearest tenth it would be 530.7)

Step-by-step explanation:

Answer:

40 shots total.

Step-by-step explanation:

First, change the percentage to a decimal:

80% = 80/100 = 0.80

Next, divide the amount of baskets made (32) with the decimal gotten to get the  total amount of shots:

32/0.80 = 40

Brandon took a total of 40 shots.

Check. Divide 32 (shots made) with the 40 (total shots in all):

32/40 = 0.8 = 80%.

Considering the equation of the parabola in vertex form, it is found that a number of -100 would have to be added to complete the square.

The equation of a quadratic function, of vertex (h,k), is given by:

[tex]y = a(x - h)^2 + k[/tex]

In which a is the leading coefficient.

In this problem, the equation is:

[tex]x^2 - 20x + 24[/tex]

Placing it in vertex form, we would have:

[tex](x - 10)^2 + 24 + c[/tex]

Applying the square of the subtraction:

[tex](x - 10)^2 = x^2 - 20x + 100[/tex]

Hence, a number of -100 would have to be added to complete the square.

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the ∠A is adjacent (adj) to  AB and opposite (Opp) of BC and AB is the hypotenuse (Hyp) of the triangle

which one of the above trig functions fits that?

sin(Ф) = BC / AC   is sin(Ф)= Opp / Hyp , so choice A) works

cos(Ф) = BC / AC  is not cos(Ф) = Opp / Hyp  so choice B) does not work

cos(Ф) = BA / AC  is cos(Ф) = Adj / Hyp  so choice C)  works

AC / BC is just a ratio   it's not the angle , so D) doesn't work
