For a craft project, four students each chose three pieces of wire from a box. Don's wires measure 3 inches, 5 inches, and 12 inches. Margo's wires measure 6 inches, 8 inches, and 14 inches. Sonji's wires measure 12 inches, 8 inches, and 17 inches. Liam's wires measure 16 inches, 8 inches, and 27 inches.

Answers

Answer:

Sonji's wires measure will be chosen

Step-by-step explanation:

Given:

Don's wires measure = 3 inches, 5 inches, and 12 inches

Margo's wires measure = 6 inches, 8 inches, and 14 inches

Sonji's wires measure = 12 inches, 8 inches, and 17 inches

Liam's wires measure = 16 inches, 8 inches, and 27 inches.

Find:

Measure used to construct a triangle

Computation:

In a triangle sum of two smaller side is grater then bigger side

a + b > c

So.

Don's wires measure = 3 inches + 5 inches < 12 inches

Margo's wires measure = 6 inches + 8 inches = 14 inches

Sonji's wires measure = 12 inches + 8 inches > 17 inches

Liam's wires measure = 16 inches + 8 inches < 27 inches.

So,

Sonji's wires measure will be chosen

Answers

Answer:

q1 (1,-3)

r1 (3,3)

s1 (0,2)

t1 (-2,-1)

Step-by-step explanation:

When a shape is reflected, it must be reflected across a line

The vertices for [tex]\mathbf{rx-axis}[/tex] of qrst are:

[tex]\mathbf{q'(1,-3)}[/tex][tex]\mathbf{ r'(3,3)}[/tex][tex]\mathbf{ s'(0,2)}[/tex][tex]\mathbf{t'(-2,-1)}[/tex]

The given parameters are:

[tex]\mathbf{q = (1,3)}[/tex]

[tex]\mathbf{r = (3,-3)}[/tex]

[tex]\mathbf{s = (0,-2)}[/tex]

[tex]\mathbf{s = (-2,1)}[/tex]

The transformation rule is given as:

[tex]\mathbf{rx-axis}[/tex]

The above rule means that the vertices are reflected over the x-axis

The rule of the transformation is:

[tex]\mathbf{(x,y) \to (x,-y)}[/tex]

So, we have:

[tex]\mathbf{q(1,3) \to q'(1,-3)}[/tex]

[tex]\mathbf{r(3,-3) \to r'(3,3)}[/tex]

[tex]\mathbf{s(0,-2) \to s'(0,2)}[/tex]

[tex]\mathbf{t(-2,1) \to t'(-2,-1)}[/tex]

Hence, the vertices for [tex]\mathbf{rx-axis}[/tex] of qrst are:

[tex]\mathbf{q'(1,-3)}[/tex]

[tex]\mathbf{ r'(3,3)}[/tex]

[tex]\mathbf{ s'(0,2)}[/tex]

[tex]\mathbf{t'(-2,-1)}[/tex]

The primes up to 50 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43 and 47. The sequence of gaps—the differences between each prime and the next—is 1, 2, 2, 4, 2, 4, 2, 4, 6, 2, 6, 4, 2 and 4. The number 1 appears only once because all primes except for 2 are odd. The rest of the gaps are even numbers.

The conjecture which could be inferred from the sequence is that it is a list of prime numbers.

From the sequence given : 2, 3, 5, 7, 11, 13

All values in the sequence are prime numbers.

Prime numbers are numbers which have only two divisors which are 1 and the number itself.

Divisors of :

2 = 1 and 2

3 = 1 and 3

5 = 1 and 5

7 = 1 and 7

11 = 1 and 11

Tamar used the algebraic method to convert the repeating decimal number to 2.45 to a fraction. Her first two steps are shown below. Step 1: x=2.45. Step 2: 100x=245.45. What should be Tamar’s next step

Answers

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

x = 2.4545... → (1)

100x = 245.4545... → (2)

Subtract (1) from (2) eliminating the repeating decimal

99x = 243 ( divide both sides by 99 )

x = [tex]\frac{243}{99}[/tex]

The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?
OA
12 inches
OB. 15 inches
OC 21 inches
OD. 40 inches

Answers

Answer:

Option B: 15 inches

Step-by-step explanation:

p=2w+2l so 12 (2*6) +2x= 42

42-12=30

30/2=15

The answer is:

15 inches

Explanation:

P = perimeter = 42

L = length = ?

W = width = 6

P rectangle = 2L + 2 W

Substitute into formula:

42 = 2L + 2 * 6

42 = 2L + 12

42 - 12 = 2L

30 = 2L

L = 30/2 = 15

L = 15 inches

z = 40° (V. O. A)

Now find x

40 + 25 + x = 180(A. S. P)

65 + x = 180

x = 180 - 65

x = 115°

Now find y

x = y (V. O. A)

It cannot be B either because it has 3 sides of equal angles. It cannot be right because non of the angles are 90 degrees. It is equilateral.

Identify an equation in point-slope form for the line perpendicular to
y=-1x +11 that passes through (4, -8).
O A. y +8 = 2(x-4)
B. y - 4 = 2(x+8)
O C. y+8 = {(x-
-4)
O D. 7-8 = {(x + 4)

Answers

Answer:

C

Step-by-step explanation:

Perpendicular lines have the exact opposite slope of the other equation.

So the slope will be x or 1x. Plug in

-8 = 1(4) + b (b represents y-intercept) like y=mx+b

-8 = 4 + b (subtract 4 on both sides)

-12 = b

The equation is y = x - 12

C

solve

y + 8 = x - 4 (subtract 8 on both sides)

y = x - 12
