Answer:
There are 270 longs
Step-by-step explanation:
Equations
We must write the problem into a mathematical model that allows us to apply the properties of basic algebra and solve for the variable which must be adequately set up.
We have three unknowns: the number of long blocks, flats blocks, and cubes. The conditions are given:
There are three times as many longs as cubes There are 30 fewer flats than longs. There are 600 blocks in allFor the equation to be easier solved, let's set the variable as the number of cubes:
x = number of cubes
Considering the first condition, we have
3x = number of longs
3x-30 = number of flats
And finally:
[tex]x + 3x+3x-30=600[/tex]
Joining like terms:
[tex]7x=630[/tex]
Solving for x
[tex]\displaystyle x=\frac{630}{7}=90[/tex]
Therefore, there are 3x = 3*(90) = 270 longs

Step-by-step explanation:
using the diagram below classify the angle pairs as corresponding, alternate interior, alternate exterior, consecutive interior, or none.
Answer:
a. ∠4 and ∠7 are consecutive interior angles
b. ∠2 and ∠11 are alternate exterior angles
c. ∠12 and ∠16 are corresponding angles
d. ∠8 and ∠13 are alternate interior angles
e. ∠11 and ∠15 are corresponding angles
f. ∠7 and ∠10 none
g. ∠1 and ∠14 are alternate exterior angles
h. ∠12 and ∠15 are consecutive interior angles
i. ∠6 and ∠7 none
j. ∠1 and ∠3 are corresponding angles
k. ∠12 and ∠16 are corresponding angles
l. ∠6 and ∠15 are alternate exterior angles
m. ∠5 and ∠10 are alternate interior angles
n. ∠8 and ∠14 are consecutive interior angles
Step-by-step explanation:
Corresponding angles are angles in similar corners of two lines that are crossed by a transversal
Alternate interior angles are angles formed on the inside but opposite sides of two lines crossed by a transversal
Alternate exterior angles are angles formed on the exterior or outer but opposite sides of two lines crossed by a transversal
Consecutive interior angles are angles on the interior part of the two lines crossed by a transversal and on the same side of the transversal
a. <4 and <7 = Consecutive interior
b. <2 and <11 = alternate exterior angles
c. <12 and <16 = corresponding angles
d. <8 and <13 = alternate interior angles
e. <11 and <15 = corresponding angles
f. <7 and <10 = none
g. <1 and <14 = alternate exterior angles
h. <12 and <15 = Consecutive interior
i. < 6 and <7 = none
j. <1 and <3 = corresponding angles
k. <12 and <16 = corresponding angles
l. <6 and <15 = alternate exterior angles
m. <5 and <10 = alternate interior angles
n. <8 and <14 = corresponding angles
First, we need to understand how angles found on parallel lines are paired and classified. An image showing the angle pairs have been attached below.
Corresponding angles pairs are indicated by the red color, orange color, and the blue colors because they occupy the same corner along the transversal line.Alternate interior angles are positioned opposite each other along the transversal line, but are inside the two parallel lines. They are the green angles.Alternate exterior angles are outside the parallel lines but lie opposite each other along the transversal. They are indicated by yellow.Consecutive angles lie opposite each other within the parallel lines. They are colored pink.Therefore, the angles given can be classified similarly using the image as:
a. <4 and <7 = Consecutive interior
b. <2 and <11 = alternate exterior angles
c. <12 and <16 = corresponding angles
d. <8 and <13 = alternate interior angles
e. <11 and <15 = corresponding angles
f. <7 and <10 = none
g. <1 and <14 = alternate exterior angles
h. <12 and <15 = Consecutive interior
i. < 6 and <7 = none
j. <1 and <3 = corresponding angles
k. <12 and <16 = corresponding angles
l. <6 and <15 = alternate exterior angles
m. <5 and <10 = alternate interior angles
n. <8 and <14 = corresponding angles

Answer:
x = 30°
Step-by-step explanation:
We know that the sum of all of the interior angles of a triangle is 180°, therefore, we can write the following equation:
x + 2x + 3x = 180
6x = 180
x = 30°

The sum of the measures of the angles of all triangles is 180 if one of the triangle measures 45 and the other two angles are equal what is the measure of each of the other two angles
Answer:
67.5
OR
45, 90
Step-by-step explanation:
The answer would either be 135, or 45, 90.
This is because typically whenever we see a all sides of a triangle equal 180, we can already understand there is a trig relationship, and when they give us one angle being 45, we see this as a 45-45-90 Triangle. (x, x, x*sqrt(2))
Or the simple but probably wrong answer would be 45 - 180 = 135. 135/2 = 67.5
In which projection map is distortion of shapes minimal and is it frequently used for countries or regions with an east-west orientation?
Answer:
The answer is C
Step-by-step explanation:
I took the test
Option (C) projection map is a distortion of shapes minimal and is it frequently used for countries or regions with an east-west orientation option (C) is correct.
What is distortion?Distortion in digital logic is the modification of a signal's original shape.
As we know,
A city map, for example, would only have a tiny deformation.
A map is a flat representation of the wavy surface of the earth. however, when a curved surface is transferred to a flat map, the curved surface seems distorted.
Thus, option (C) projection map is a distortion of shapes minimal and is it frequently used for countries or regions with an east-west orientation option (C) is correct.

The perimeter of a rectangle is 77cm. The length is 6 times the width. Find the width and length of the rectangle. HELPPP I’m stuck on this
Answer:
462
Step-by-step explanation:
multiple 77x6
Answer:
The width is 5.5cm.
The length is 33cm.
Step-by-step explanation:
Since the length is 6 times the width, [tex]l=6w[/tex] (l represents the length and w represents the width.)
Perimeter = Length + Length + Width + Width = [tex]6w+6w+w+w=14w[/tex]
Since the perimeter is 77cm,
[tex]14w=77[/tex]
Divide both sides by 14:
[tex]\frac{14w}{14}=\frac{77}{14}[/tex]
[tex]w=5.5[/tex]
The width is 5.5cm.
We know that the length is 6 times the width,
so the length = [tex]6\times 5.5=33[/tex].
The length is 33cm.

Circle O is shown. Secants C A and C E intersect at point C outside of the circle to form an angle with measure 36 degrees. Secant C A intersects the circle at point B, and secant C E intersects the circle at point D. Arc B D is 48 degrees. In circle O, what is mArc A E?
Answer:
120°Step-by-step explanation:
The external angle <C outside the circle can be expressed in terms of length of arc AE and BD using the formula below.
<C = [tex]\frac{AE-BD}{2} \\[/tex]
Next is to make the length of arc AE the subject of the formula;
<C = [tex]\frac{AE-BD}{2} \\[/tex]
cross multiply
[tex]2<C = AE-BD[/tex]
add BD to both sides of the equation
[tex]2<C+BD = AE-BD+BD\\2<C +BD = AE[/tex]
[tex]AE = 2<C +BD[/tex]
Given
<C = 36°
arc BD = 48°
Substitute the given parameters into the formula;
[tex]AE = 2<C +BD\\AE = 2(36)+48\\AE = 72+48\\AE = 120^0\\[/tex]
Hence mArc is 120°

its C, 120

Examples:
Decimals that end or repeat (in your case)
Fractions

Yes, the number 5.565656... is a rational number.
We have,
A rational number is defined as any number that can be expressed as the quotient or ratio of two integers, where the denominator is not zero.
In the case of 5.565656..., it is a repeating decimal.
However, repeating decimals can always be expressed as a fraction.
Let's represent 5.565656... as x:
x = 5.565656...
Now, if we multiply both sides of the equation by 100 (to remove the repeating decimal), we get:
100x = 556.565656...
Subtracting the original equation from the above equation, we have:
100x - x = 556.565656... - 5.565656...
99x = 551
x = 551/99
The fraction 551/99 is a ratio of two integers, and it represents the value of 5.565656....
Therefore,
5.565656... is a rational number.
