Answer:

x = 76°

Step-by-step explanation:

We can solve this by using the angles of intersecting chords theorem. This tells us that when two chords intersect inside a circle, the angle formed is half of the sum of the intercepted arcs of the angle.

This implies that the angle 94° should be half of the sum of Arc measuring x° and the arc measuring 112°. So we can write the equation as:

[tex]94=\frac{1}{2}(x+112)\\[/tex]

We can simplify and solve for x:

[tex]94=\frac{1}{2}(x+112)\\\\94=\frac{1}{2}x+56\\94-56=\frac{1}{2}x\\38=\frac{1}{2}x\\x=38*2=76[/tex]

Hence, x = 76°

Answer:

Choice c is the answer.

Step-by-step explanation:

We have given a expression.

Answer:

[tex]V=250\ cm^{3}[/tex]

Step-by-step explanation:

step 1

Find the length of the base L

we know that

The surface area of a rectangular prism is equal to

[tex]SA=2B+PH[/tex]

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

substitute

[tex]SA=2(LW)+2(L+W)H[/tex]

we have

[tex]W=5\ cm[/tex]

[tex]H=10\ cm[/tex]

[tex]SA=250\ cm^{2}[/tex]

substitute in the formula and solve for L

[tex]250=2(5L)+2(L+5)10[/tex]

[tex]250=10L+20L+100[/tex]

[tex]30L=250-100[/tex]

[tex]L=5\ cm[/tex]

step 2

Find the volume of the rectangular prism

The volume is equal to

[tex]V=(LW)H[/tex]

we have

[tex]W=5\ cm[/tex]

[tex]L=5\ cm[/tex]

[tex]H=10\ cm[/tex]

substitute

[tex]V=(5*5)*10=250\ cm^{3}[/tex]

Answer:

D. (2,1)

Step-by-step explanation:

Fill in the value for y from the first eq (6x-11) into the second:

-2x - 3(6x-11) = -7

Now simplify:

-2x -18x + 33 = -7

-20x = -7-33

20x = 40

x = 2

Now that we have x, plug it into the top eq to get y:

y = 6*2 - 11 = 1

Et voila, x=2 and y=1, so the solution is (2,1).

Answer:

X= 2 and Y=1

Step-by-step explanation:

✯Hello✯

↪  So you know what y is so you can substitute into -2x-3y=-7

↪  -20x+33=-7 (thats after you expand the brackets)

↪ -20x=40

↪  this means that x=2. Therefore if u substitute y=1 and its on the options

Answer:

  4 oz of water must be evaporated

Step-by-step explanation:

If we let x represent the amount of water to be evaporated, the relation between the solutions is ...

  0.08 · 36 oz = 0.09 · (36 -x) oz

  0.09x = 36(0.09 -0.08) . . . . . divide by oz; add .09x, subtract .08·36

  x = 36· 0.01/0.09 = 36/9 = 4

Answer:

C) 3(5)^6

Step-by-step explanation:

Note the amount of 5's inside the expression and 3's inside the expression.

In the given expression (3 x 5 x 5 x 5 x 5 x 5 x 5), there are 6 5's and 1 3's.

Note that, when changing multiplication into powers, the amount of the same number multiplied together will equal the number you put as a power. For example:

5 x 5 = 5²

5 x 5 x 5 = 5³

In this case:

5 x 5 x 5 x 5 x 5 x 5 = 5^6

Note that there is still a 3 multiplied inside the expression, and so remember to keep it in the answer.

3(5)^6, or C) is your answer.

Final answer:

The constant of proportionality for the relationship between the length of the arc intercepted by an 80 degree angle and the radius of the circle is π/9 or approximately 0.349 radians per unit of length.

Explanation:

The constant of proportionality for the relationship between the length of the arc intercepted by an 80 degree angle and the radius of the circle is π/9 or approximately 0.349 radians per unit of length.

This can be determined by using the formula for arc length: L = 2πr(A/360), where L is the length of the arc, r is the radius of the circle, and A is the angle in degrees. Since we know that A = 80 degrees, we can substitute the values into the formula to find the constant of proportionality.

L = 2πr(80/360) = (π/9)r

The expression for when the GCF is factored is -4(y² - 3y + 4). Option D

To factor out the Greatest Common Factor (GCF) from the expression [tex]-4y^2 + 12y - 16[/tex] first, find the GCF of the terms.

The GCF of the coefficients 4, 12, and 16 is 4.

Additionally, there is a common factor of y²  in all terms.

Now, we have to actor out the GCF, which is -4, we get;

-4(y² - 3y + 4)

Therefore, the expression -4(y² - 3y + 4) represents the factor GCF from the original expression

Answer:

y= 3|x|+5

Step-by-step explanation:

Remember the graph for |x| is shown on the attached picture

Since the picture you show tell us that y=5 when x=0

we have something like the following y=a|x|+5, where 'a' is a constant that represents the slope of the line (whether is the line from one side of the 'y' axis or from the other), we can see that, when x=1, y=8, so we have another point

we can use the equation for slopes using points 1 (0,5) and 2 (1,8)

thus we have that [tex]a=\frac{8-5}{1-0}=3[/tex]

So the answer is y= 3|x|+5

twenty seven percent.

The percent change in the price of gasoline from September to October is calculated using the formula for percent change. Subtracting the September price from the October price and dividing by the September price yields a 15% increase.

To calculate the percent change in the price of gasoline from September to October, we use the formula for percent change, which is
(New Price - Old Price) / Old Price
x 100%. In this case, the price in September was $1.80, and the price in October was $2.07.

The percent change can be calculated as follows:

Therefore, the percent change in the price of gasoline from September to October is 15%.
