What percent is equivalent to 1/25?
4%
5%
20%
25%

Answer:

D

Step-by-step explanation:

because we know that angle EOD is less the 90 so that means that it is complementary. For AOB it is  the same but we can check by adding 35 plus x plus 90 =180 degrees  so 35+90=125  x=180-125=55 so x=55 and 55 is less then 90  so it is a complementary angle.

Step-by-step explanation:

The exterior angles of a triangle add to 360 degrees

133+134+x = 360

267+x =360

Subtract 267 from each side

267+x-267 = 360-267

x =93

Answer:

-5

Step-by-step explanation:

What is the slope of the line represented by the equation y = – – 5x

The equation of the line is given in slope-intercept form. The slope is simply the coefficient of x in the equation.

The slope of the line is thus -5

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cutoff point with the y axis

To find the slope two points are needed through which the line passes:

[tex]m = \frac {y2-y1} {x2-x1}\\m = \frac {8-8} {- 5 - (- 2)} = \frac {0} {- 5 + 2} = \frac {0} {- 3} = 0[/tex]

THE equation is of the form:

[tex]y = b[/tex]

We substitute the y coordinate of the point (2,8)

[tex]8 = b[/tex]

Then, [tex]y = 8[/tex]

Answer:

[tex]y = 8[/tex]

Answer:

D.

Step-by-step explanation:

A term in a polynomial is a single number or a number multiplied by any number of variables. A polynomial is a sum of terms.

The only thing that can be done with variables in a polynomial is to multiply them by numbers or other variables. In a polynomial, you cannot: divide by a variable (have a variable in a denominator), have a root of a variable, have a log of a variable, have a variable as an exponent, etc.

All expressions are polynomials except for D. In D., the negative exponents mean division by variables.

ANSWER

The diameter is 8 units.

EXPLANATION

A portion of the y-axis is serving as the diameter of the circle.

The portion of the y-axis that intersects the circle at two points.

We can use these intercepts to find the diameter.

There is a y-intercept at y=2 and y=-6.

The distance between the two intercepts is the diameter of the circle.

[tex] |2 - - 6| = |2 + 6| = 8[/tex]

Therefore the radius is 8 units.

Answer: [tex]diameter=8\ units[/tex]

Step-by-step explanation:

By definition, the radius of a circle is the distance from its center to its edge.

We need to remember that diameter of a circle is twice the radius:

[tex]diameter=2(radius)[/tex]

Then, you can observe in the figure that there are 4 units between the center of this circle and its edge, therefore the radius is:

[tex]radius=4\ units[/tex]

Finally, you need to substitute the radius calculated into the formula  [tex]diameter=2*radius[/tex] to find the value of the diameter of this circle. Then, this is:

 [tex]diameter=2(4\ units)[/tex]

 [tex]diameter=8\ units[/tex]

Answer:

Step-by-step explanation:

4x = 32 - x2 would be much clearer if written as 4x = 32 - x^2.  Please use

" ^ " to indicate exponentiation.

Rewrite 4x = 32 - x^2 in the standard form of a quadratic:  x^2 + 4x - 32

Then the coefficients are a = 1, b = 4 and c = -32.

Find the discriminant.  It is b^2-4ac.  

Here, b^2-4ac = 4^2 - 4(1)(-32), or 16 + 128, or 144.

Because the discriminant is positive, we know immediately that this quadratic has two real, unequal roots.

So, the answer to this question is "the graph of 4x = 32 - x^2 cross the x-axis in two places."

Answer:

How many times does the graph of 4x = 32 - x2 cross the x-axis?

Answer:

Solve the equation

[tex]\displaystyle \frac{8.8 + 9.5 + 9.2 + x}{4} \ge 9.1[/tex],

where [tex]x[/tex] is the minimum score of the fourth judge.

At least 8.9 points.

Step-by-step explanation:

Let the score of the fourth judge be [tex]x[/tex].

The average score is the sum of the four judges' score divided by the number of scores. That is:

[tex]\displaystyle \text{Average Score} = \frac{8.8 + 9.5 + 9.2 + x}{4}[/tex].

The minimum average score needs to be greater than or equal to [tex]9.1[/tex]. In other words,

[tex]\displaystyle \frac{8.8 + 9.5 + 9.2 + x}{4} \ge 9.1[/tex].

Multiply both sides of by four.

[tex]8.8 + 9.5 + 9.2 + x = 4\times 9.1[/tex].

Subtract [tex]8.8 + 9.5 + 9.2[/tex] from both sides of the equation:

[tex]x = 4\times 9.1 - (8.8 + 9.5 + 9.2) = 8.9[/tex].

In other words, the minimum score of the last judge is [tex]8.9[/tex] for Julie to move on.

Answer:

a. 64 tickets.

b. $11.

Step-by-step explanation:

[tex]y[/tex] is given as [tex]37[/tex], and the question is asking for the value of [tex]x[/tex].

Solve this equation with respect to [tex]x[/tex].

[tex]0.50x + 5.00 = 37[/tex].

Subtract 5.00 from both sides of this equation:

[tex]0.50x = 32[/tex].

[tex]\displaystyle x= \frac{32}{0.50} = 64[/tex].

In other words, 64 tickets were purchased.

[tex]x = 12[/tex], and the question is asking for the value of [tex]y[/tex].

Replace [tex]x[/tex] with 12 and evaluate the expression [tex]y = 0.50x + 5.00[/tex] for [tex]y[/tex].

[tex]y = 0.50\times 12 + 5.00 = 11.00[/tex].

In other words, $11.00 were spent.

Answer:

The coordinates of her new position are (0 , -5) ⇒ answer B

Step-by-step explanation:

* Lets revise some translation

- If the point (x , y) translated horizontally to the right by h units

 then the new point = (x + h , y)

- If the point (x , y) translated horizontally to the left by h units

 then the new point = (x - h , y)

- If the point (x , y) translated vertically up by k units

 then the new point = (x , y + k)

- If the point (x , y) translated vertically down by k units

 then the new point = (x , y - k)

* Now lets solve the problem

∵ Nancy start from position (2 , -3)

- She walks 5 blocks to the right and 3 blocks down

∴ Add x-coordinate by 5 and subtract y-coordinate by 3

∵ The starting position is (2 , -3)

∴ The new position is (2 + 5 , -3 - 3) = (7 , -6)

- She walks 7 blocks to the left and 1 block up

∴ Subtract x-coordinate by 7 and add the y-coordinate by 1

∴ The new position is (7 - 7 , -6 + 1) = (0 , -5)

* The coordinates of her new position are (0 , -5)

Answer:

Option D

Step-by-step explanation:

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.

In plain English, the definition means:

The range is the resulting y-values we get after substituting all the possible x-values.

How to find the range

1.The range of a function is the spread of possible y-values (minimum y-value to maximum y-value)

2. Substitute different x-values into the expression for y to see what is happening. (Ask yourself: Is y always positive? Always negative? Or maybe not equal to certain values?)

3. Make sure you look for minimum and maximum values of y.

4. Draw a sketch! In math, it's very true that a picture is worth a thousand words.

Answer:

10*7+ 18x *7 =2590

or 70 + 18x*7  =2590

Step-by-step explanation:

10*7 to find out how much the shipping costs for the 7 teams altogether

18*x  because you need to find how much the jerseys cost for all the soccer teams

then multiply it by 7 to find how many players on each team

when you solve for x you get 20

there are 20 players on each on team.

Final answer:

To determine the number of players on each soccer team, given the total jersey order cost for all teams, the equation 7(18x) + 7(10) = 2590 can be used, where x represents the number of players.

Explanation:

The question asks which equation can be used to determine x, the number of players on each team, given that the total cost to order jerseys for all the teams is $2,590, the cost per jersey is $18, and the shipping per team is $10, with 7 teams ordering. To find the equation, we first outline the total costs involved: the cost of the jerseys plus the shipping cost for all teams.

Let's denote x as the number of players on each team.

The cost for jerseys for one team would be 18x (since each jersey costs $18), and the cost to outfit all 7 teams would be 7 times that amount, plus the total shipping cost for all teams (7 teams times $10 per team).

So, the equation can be represented as:

7(18x) + 7(10) = 2590

This equation accounts for both the per-jersey cost and the fixed shipping fee for each team, totaling up to the overall cost reported.

Answer:

Step-by-step explanation:

Find the discriminant, b^2-4ac:  Here a = 1, b = -5 and c = 5.

Then the discriminant is (-5)^2-4(1)(5) = 5, and so there are 2 real, different roots.  The roots are:

      -(-5) ±√5

x = ----------------,   which correspond to answers A and C.

           2(1)

The roots of the equation will be (5 - √5) / 2 and (5 + √5) / 2. Then the correct options are A and C.

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have

The quadratic equation is given below.

x² - 5x + 5 = 0

Then the root of the equation is given as

[tex]\rm x = \dfrac{ - (-5) \pm \sqrt{(-5)^2 - 4*1*5}}{2*1}\\\\x = \dfrac{5 \pm \sqrt{25-20}}{2}\\\\x = \dfrac{5 \pm \sqrt5}{2}\\\\x = \dfrac{5 - \sqrt5}{2}, \dfrac{5 + \sqrt5}{2}[/tex]

Thus, the correct options are A and C.

Check the picture below.

recall the ambiguous SSA case, as the "12" side moves, it ends up with two supplementary angles on the base.

Answer:

see explanation

Step-by-step explanation:

Given

x + 4y = 36

To find the x- intercept, let y = 0 in the equation and solve for x

x + 0 = 36 ⇒ x = 36 ← x- intercept

To find the y- intercept let x = 0 in the equation and solve for y

0 + 4y = 36 ⇒ y = 9 ← y- intercept

Answer:

x-intercept is 36; y-intercept is 9.

Step-by-step explanation:

Given equation of the line,

[tex]x+4y=36[/tex]

For x-intercept ( the point at which the line intersects the x-axis ),

y = 0,

[tex]\implies x+4(0) = 36[/tex]

[tex]x=36[/tex]

⇒ The value of x-intercept is 36,

Now, for y-intercept( the point at which the line interests the y-axis )

x = 0,

0 + 4y = 36

⇒ y = 9

⇒ The value of y-intercept is 9.

Hence, first option is correct.

Answer:

There are 12 multiple choice

Step-by-step explanation:

Let m = multiple choice

f = free response

f+m = 15 since there are 15 questions

3m+5f = 51  since we have 51 minutes and 3 for multiple choice and 5 for free response

We have 2 equations and 2 unknowns

m+f = 15

3m+5f = 51

Multiply the first equation by -3

-3(m+f) = -3*15

-3m -3f = -45

Add this to the second equation

-3m-3f = -45

3m+5f = 51

---------------------

        2f = 6

Divide by 2

2f/2 = 6/2

f = 3

There are 3 free response.

m+f = 15

m+3 = 15

Subtract 3 from each side

m+3-3=15-3

m=12

There are 12 multiple choice

Step-by-step explanation:

The volume (V) of a pyramid is calculated as

V = [tex]\frac{1}{3}[/tex] area of base × perpendicular height (h)

area of square base = 12 × 12 = 144 units² and h = 8, hence

V = [tex]\frac{1}{3}[/tex] × 144 × 8 = [tex]\frac{1152}{3}[/tex] = 384 units³ → B

Volume of the pyramid is equal to [tex]384 \ unit^{3}[/tex].

" Volume is defined as the total space occupied by any three- dimensional object enclosed in it."

Formula used

Volume of a pyramid [tex]= \frac{1}{3} \times Area \ of \ the \ base \times height[/tex]

Area of a square [tex]= s^{2}[/tex]

[tex]s=[/tex] Side length

According to the question,

Given dimensions of pyramid,

Height of the pyramid [tex]= 8 \ units[/tex]

Base of the pyramid is square in shape

Side length of a square [tex]= 12 \ units[/tex]

Substitute the value in the formula to get the area of the base,

Area of the base [tex]= 12 \times 12[/tex]

                            [tex]= 144 \ units^{2}[/tex]

Substitute the value to get the volume of the pyramid,

Volume of the pyramid [tex]= \frac{1}{3} \times 144 \times 8[/tex]

                                       [tex]= 48 \times 8\\\\= 384 \ units^{3}[/tex]
