The two angles are supplementary angles and need to equal 180 degrees.

x = 180-108 = 72

answer: x = 72 degrees

Answer:

72°

Step-by-step explanation:

108+x=180° {Sum of angles ofon a straight line)

x=180- 108

x=72°

Answer:

  (i) 0.2 kg

  (ii) kg/cm³

  (b) 2.29 kg

Step-by-step explanation:

This problem gives you relations between units, and the formulas for density and mass. It is asking you to make use of these relations in various mass and density calculations.

The relationship between kg and pounds can be used to write a units conversion multiplier. It will have numerator equal to denominator, but will have units such that multiplying by it will give the units you want.

  0.44 pounds × multiplier = __ kg

  0.44 pounds × (1 kg)/(2.2 pounds) = (0.44/2.2)(1 kg)

  0.44 pounds = 0.2 kg

__

The formula can be used to find the units of interest:

  Density = mass/volume

  units of density = (units of mass)/(units of volume)

  units of density = kg/cm³

__

Using the given formula with the given value of L, we find the volume to be ...

  V = 4(1.40 cm)(3 -1.40 cm)² = 14.336 cm³

Then the mass is ...

  mass = volume × density

  mass = (14.336 cm³)×(0.160 kg)/(1 cm³) = 2.29376 kg

The mass is about 2.29 kg.

_____

Additional comment

Often you will see density in terms of kg/m³ or g/cm³. Water has a density of about 1 g/cm³ or 1000 kg/m³. The most dense non-radioactive element in the periodic table is osmium, with a density of about 22.6 g/cm³, or 0.0226 kg/cm³. The material in part (b) of this problem has a density about 7 times that, so is clearly not from Earth.

Answer:

1. -1

2. 3

3. (2, 5)

Step-by-step explanation:

y axis is |

x axis is _

A intersects the y axis at -1

B intersects the y axis at 3

A and B intersect at (2, 5) because the x value is 2 because it goes right twice and the y value is 5 because it goes up 5 and theres the point of intersection

Answer: 143.089 or 143.1

well, the smaller triangle is a miniature replica of the big triangle, so you have to find the scale between both triangles bases by doing 122/1.62=75.31 and then use that number to multiply by the height of the smaller triangle giving you the height of the bigger triangle so 75.31*1.9=143.089 or 143.1

Answer:

(7, 4)

Step-by-step explanation:

The rule to rotate a point/figure 90° clockwise about the origin is (x, y) -> (y, -x). We are given the point as (-4, 7).

Therefore, the answer is (7, 4).

Answer:

Measure all sides of the triangle (all 3 sides), and depending on the lengths see if they are all equal, if two are equal, or if there are no equal sides at all. If there are all equal side lengths you have an equilateral triangle that has 3 congruent, aka equal sides.

Step-by-step explanation:

If two angles and the included side of one triangel are equal to the corresponding angel and the side of another triangel, the triangles are congurent.

Divide miles traveled by percentage.

666/0.74 = 900

total length is 900 miles

Step-by-step explanation:

I'm not 100% sure if this is the answer but here was my thinking process:

1/4 of 24 is 6, and 6 + 3 is 9, so the brothers age is probably 9, and then 24-9 is 15, and the difference between 15 and 9 is 6. Once again I don't know if this is right or not, but either way I hope this helps!

The distance minute hand tracked from 2 to 6 is  5.23 inches.

A clock can be thought of as a circle having 12 steps and we know that circle is 360°,

So, the measure of each integer step of a clock is 30°or π/12 rad.

We know the circumference of a circle is 2πr.

From 2 to 6 the minute hand rotated (4×30°) = 120° = 2π/3 rad.

We know arc length(S) = r×Ф.

∴ The distance minute hand tracked is = (2.5)×(2π)/3 inches.

= 5.23 inches.

Step-by-step explanation:

First of all the equation is subtracttion since they used to word *difference* which indicates subtract. To find the different between how much Anna at and how much she gave her brother we would subtract 5/8 by 3/8.

to solve this equation ( 5/8 - 3/8 ) the denominator of both fractions have yo be the same and that is true for this equation. Then you would subtract the numerators and keep the denominator the same. So the answer is 2/8

Answer:

104/100

Step-by-step explanation:

The easiest way to do this problem is to convert the fraction 6/10 to have the same denominator as the other fractions, which in this case is ?/100.

we can convert 6/10 to have 100 as a denominator by multiplying the fraction by 10

[tex]\frac{6}{10} *10=\frac{60}{100}[/tex]

now we can just add the fractions together!

[tex]\frac{17}{100} +\frac{17}{100} +\frac{60}{100} =\frac{104}{100}[/tex]

Answer:

Step-by-step explanation:

If 5 cm on the model = 4 feet in real

Then, what does 1 cm on the model = in real?

5/4=1.25

So, 1 cm on the model = 1.25 ft

Now, what does 3cm long in the model = to in real?

1.25x3=3.75

So hence, the length of the Dog house is actually 3.75 feet.

Given that the parent function, y = x², has a leading coefficient of 1, the

following are the comparisons of the equations with the parent functions;

[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]

The parent function is y = x²

The leading coefficient of the parent function = 1

The steepness of a quadratic equation is given by the value of the

leading coefficient.

When the leading coefficient is larger than 1, we have;

The function is steeper than y = x²

When the leading coefficient is a fraction larger than 0 but lesser than 1, we have;

The function is less steep than y = x²

Which gives;

[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]

The function y = -x² is inverted has the same steepness as y = x², but will not be used.

Answer:

Step-by-step explanation:

Answer:

7.5

Step-by-step explanation:

Ok so this is how I got it:

Since we know the lengths of sides NO, MN, and JK, but we don't know the length of KL, we can use what we know.

To get from MN to JK, we multiply MN (2) by 1.5 to get 3. So you can go the same thing to get from NO to KL.

Just go ahead and multiply 5 by 1.5

5 × 1.5 = 7.5

Hope this helps!

Answer:

KL = 7.5

Step-by-step explanation:

MN : JK = NO : KL

⇒ 2 : 3 = 5 : KL

[tex]\implies \dfrac23=\dfrac{5}{KL}[/tex]

⇒ 2 · KL = 5 · 3

⇒ 2(KL) = 15

⇒ KL = 15 ÷ 2

⇒ KL = 7.5

Point slope form of the equations:

y = -3x + 8

y = 2x - 2

Solution to the system of equations:

(x, y) ==> (2, 4)

Step-by-step explanation:

6x + 2y = 16

2x - y = 2

6x + 2y = 16

2(2x - y = 2)  ==> 4x - 2y = 4

6x + 2y = 16

4x - 2y = 4

10x = 20

/10     /10

x = 2

Now, we solve for y:

6x + 2y = 16

6(2) + 2y = 16

12 + 2y = 16

-12         -12

2y = 4

/2   /2

y = 2

(x, y) ==> (2, 2)

Point-slope forms:

6x + 2y = 16

-6x          -6x

2y = -6x + 16

/2        /2

y = -3x + 8

2x - y = 2

-2x      -2x

-1y = -2x + 2

/-1       -1

y = 2x - 2
