Answer:

w=9

Step-by-step explanation:

short answer 2 and 6 are the same size with three x difference, so three times three is nine.

Answer: A

Step-by-step explanation:

We have to find the perimeter of the figure.

For doing so, we have to find the length of all the sides of a quadrilateral

The length of a line segment joining points (x1,y1) and (x2,y2) is given by the distance formula:  

after finding length of all the sides, we add the length of each side to get the perimeter.

Use the distance formula to find the length of each side, and then add the lengths.

Answer: 336 hr

Step-by-step explanation:

Given

The speed of the van is 45 mph

The speed of the family car is 60 mph

distance traveled by van in 112 hours is

[tex]d_1=45\times 112=5040\ miles[/tex]

After 112 hours family car started its Journey. Suppose, van travels another x miles after the family car started its Journey

So, distance traveled by the family car in 't' hours

[tex]\Rightarrow 60\times t=112\times 45+45\times t\\\\\Rightarrow 15 t=5040\\\\\Rightarrow t=\dfrac{5040}{15}=336\ hr[/tex]

So, after traveling 336 hr, the family car will catch the van

Answer:

area 12.566

circumference 12.566

Step-by-step explanation:

Answer:

Circumference= 6.28 meters

Area=12.56 in²

Step-by-step explanation:

[tex]C=r*pi[/tex]

[tex]C=2*3.14[/tex]

[tex]C=6.28[/tex]

[tex]A=pi*r^2[/tex]

[tex]A=3.14*4[/tex]

[tex]A=12.56[/tex]

Answer:

There are no real factors for this.

Step-by-step explanation:

We could answer this either by checking each listed expression to see whether it is a factor of 9r^2-4r+1, or

We could take the coefficients of 9r^2-4r+1, determine the quantity b²-4ac (called the 'discriminant') and draw a conclusion based upon whether the discriminant is -, + or 0.

Let's use the 2nd approach.

Here, a = 9, b = -4 and c = 1.

Then the discriminant is b²2 - 4ac, or (-4)² - 4(9)(1), or 16 - 36.

Since 16 - 36 is negative, we conclude that this 9r^2 - 4r + 1 has NO REAL FACTORS.

Answer:

BE=24

Angle EBC=33

Step-by-step explanation:

Rectangle diagonals are congruent so

[tex]3x + 6 = 6x - 12[/tex]

[tex]3x + 18 = 6x[/tex]

[tex]18 = 3x[/tex]

[tex]x = 6[/tex]

Plug that in one of the equations.

[tex]3(6) + 6 = 24[/tex]

BE=24.

ECD is apart of Isoceles triangle EDC.

Another isoceles triangle is EAB.

They triangle share two sides( remeber all diag ki bals in a rectangle are congruent) and a angle E, so they are congruent triangles.

That means Angle EBA measures 57 degrees.

Angle EBC and Angle EBA add up to 90 degrees so

Angle EBC=33

B

Answer:

[tex]\boxed {\boxed {\sf 32+8k}}[/tex]

Step-by-step explanation:

We are given the expression:

[tex]8(4+k)[/tex]

To solve, distribute the 8. Multiply each term inside the parentheses by 8.

[tex](8*4)+ (8*k) \\ (32)+(8k) \\32+8k[/tex]

The expression is equal to 32+8k

Answer:

M

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

The solution is,  (c)  Yes, because angle 3 and angle 6 are congruent.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

given that,

Angles 3 and 6 are "alternate interior" angles. When those angles are congruent, as these are, then the lines crossed by the transversal are parallel.

we have,

We expect angles 5 and 6 to be supplementary because they are a linear pair.

That fact says nothing about the relationship of line d to line c.

Hence, The solution is,  (c)  Yes, because angle 3 and angle 6 are congruent.

Answer:

3/45

Step-by-step explanation:

Answer:

24442 square inches of decorative paper

Step-by-step explanation:

To solve for the above question, we have to find the Surface Area of the box. The box is shaped as a Rectangular Prism.

Hence, the formula is given as:

A = 2(wl + hl+ hw)

Where:

Length (l) = 99 inches

Width (w) = 55 inches

Height (h) = 44 inches

=2 × (55×99 + 44×99 + 44×55)

=24442 square inches

Therefore, the minimum amount of decorative paper needed to cover the box is 24442 square inches of decorative paper.

Answer:

b)34°

Step-by-step explanation:

Answer: I’m pretty sure that BD should also be 150

Step-by-step explanation:

The measure of angle O is 75 because the angle is always half of the arc, so knowing that, and also cd and abs are congruent, the other side of o is probably the same as the other, so it’d be 75, multiply by 2 and itll be 150.
