Lou is playing an online trivia game. She has 20 points and earns 4 points for
each correct answer. She will advance to the next round if her score is over 55
points.
Which inequality can Lou use to find how many more questions she must
answer correctly to advance to the next round?
O A. 4x + 55 < 20
O B. 4x + 20 > 55
O C. 20x+4 > 55
D. 4x + 20 < 55

Answer:

∠ C = 35°

Step-by-step explanation:

The sum of the 4 interior of a kite = 360°

The opposite angles D and F are congruent, that is

∠ F = 125°

Sum the 4 angles and equate to 360°, thus

∠ C + 125° + 75° + 125° = 360°

∠ C + 325° = 360° ( subtract 325° from both sides )

∠ C = 35°

Answer: The y-intercept is 22 spaces higher.

Step-by-step explanation: Given function is .

And transformed function equation .

We can see 22 is being added to the given function f(x) to get the transformed function.

Note: According to transformation rule, y = f(x) +k shift k units up.

22 is being added to the original function. So,   function would shift 22 units up that is y-intercept is 22 spaces higher.

Therefore , correct option is : The y-intercept is 22 spaces higher.

Answer:

the y-intercept is 22 spaces higher.

Step-by-step explanation:

Since f(x) = y, when f(x) is increased 22 spaces, it goes upward on the y-axis 22 spaces.

Answer:

A) t=5d

Step-by-step explanation:

Since the problem states "He rode 1 mile in 5 minutes",  that means for every mile Andre travels, it will take him 5 minutes for each mile.

Therefore, the equation that best works is t=5d because the coefficient is 5 where it's the slope representing 5 minutes per mile.

Answer:

Step-by-step explanation:

step one:

given data

we are given the equation of the circle as

[tex](x -4)2^ + (y + 6)^2 = 64[/tex]----------------1

We know that the general equation for a circle is

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

comparing the two equations above, we can immediately compare the term on the other side of the equality sign that is

r^2=64

square root both sides

r=√64

r=8

since the radius is 8, hence the diameter is

d=2

r= 2*8

=16

Answer:There are six important properties of parallelograms to know:

Opposite sides are congruent (AB = DC).

Opposite angels are congruent (D = B).

Consecutive angles are supplementary (A + D = 180°).

If one angle is right, then all angles are right.

The diagonals of a parallelogram bisect each other.

Each diagonal of a parallelogram separates it into two congruent

Answer:

293000

Step-by-step explanation:

Since were rounding to the nearest thousand, we're looking at the hundred digit. If it's 5 or great, we round up. If it's 4 or less, we round down.

In this case, it's 5. So we round 292500 up to 293000

Answer and explanation:

Surface area of a rectangle = length * width

Surface area of a square = a² where a is length of a side

To find total surface area of the the five pieces of paper, we add up all the areas of all the shapes

Given that length of rectangle =3.5

And width = 2

Area of rectangle =3.5*2=7

Area of 3 rectangles given they are all equal = 7*3=21

Since width of rectangle equal to width of square and all sides of square are equal

Area of square = 2 *2 =4

Area of the two squares =4*2=8

Total surface area of the five plane shapes = 21+8= 29

Answer:

a. Point.

b. Vertex.

c. Line.

d. Line segment.

e. Ray.

Step-by-step explanation:

a. Point: a location, has no dimension. Also, a point doesn't have a size i.e no length, depth, breadth or height.

b. Vertex: is the common endpoint of two segments or rays that form the "corner" of an angle.

c. Line: is an infinite number of points extending in opposite directions that has only one dimension.

d. Line segment: is part of a line that has two endpoints.

e. Ray: is part of a line that has one endpoint and continues in one direction infinitely.

Answer:

No. are 35&43

Step-by-step explanation:

Let the one no. Be= X

Then the other no.= X+8

Sum of both no.= X+ X+8= 2X+8

When sum is increased by 17 = 2X+8+17=95

2X+25=95

2X=70

X=35

Other no=X+8= 35+8=43

 6  =   x        

 8     x + 8

8x = 6x + 48

8x - 6x = 48

2x = 48

x = 48/2

x = 24

The value of x is 6.

Those triangles look the same but are different in size.

And in similar triangles,

the corresponding sides are in proportion to each other and the corresponding angles are equal to each other.

Given:

The triangle ABC and AED are similar triangles.

So,

the corresponding sides are in proportion of each other.

ED/CB = AD / AB

8/6 = 8/x

x = 6

Therefore, the value of x is 6.
