Answer:

taco is 80 cents burrito is 1.50

Step-by-step explanation:

If you make two equations, multiply one of them by two so burritos have the same constant, subtract and find b. Then, substitute b into one of the equations to find t. Hope it helps.   :)

Answer:

2,5

Step-by-step explanation:

since radius is 5

each point lies on the circumference that has 5 or -5 in its y coordinates must have -3 in its x coordinate because -3 is the center

then option number 1 is incorrect

second option is correct , -3 + ( -5 ) = -8

third option is correct, -3 + 5 = 2

fourth is correct, -3 is the center and 5 steps on y axis

fifth is the same as fourth but opposite direction

so the first one is the exception

Basically, just plug in the expressions into the formula and simplify:

[tex]A = \frac{1}{2}*(3ab)*(7a^2b+11a^2b) = \frac{3}{2}ab*(18a^2b) = 27a^3b^2[/tex]

Answer:

[tex]\sf f(-3) = 23[/tex]

given:

[tex]\sf f(x) = 3x^2 -4[/tex]

to find the output, replace x with the given integer.

solve:

[tex]\sf f(-3) = 3(-3)^2 -4[/tex]

[tex]\sf f(-3) = 3(9) -4[/tex]

[tex]\sf f(-3) = 27 -4[/tex]

[tex]\sf f(-3) = 23[/tex]

Answer:

b = 70

b = a = 70

b = c = 70

Step-by-step explanation:

snice b and 70 are opposite the top; they are equal.

b and a are alternate internal they are again equal so a is 70.

and finally a is equal with c because they are opposite at the top.

Exponential equations are equations in which variables occur as exponents. For example, exponential equations are in the form ax=by . To solve exponential equations with the same base, use the property of equality of exponential functions

Answer:

(-3, 7)

Step-by-step explanation:

The rotation of an object turns the object around a fixed point called the center of rotation.  

Positive rotations are counterclockwise.

Negative rotations are clockwise.

Therefore, rotation of 90° about the origin means a 90° rotation counterclockwise with (0, 0) as the center of rotation.

The rule for rotation of 90° about the origin is:

(x, y) → (-y, x)

Therefore  (7, 3) → (-3, 7)

The rule of 90° rotation about the origin is

Here given point is

The new point is

Answer:

83, acute

Step-by-step explanation:

49 + 48 + x = 180

97 + x = 180

x = 83

All angles are smaller than 90 so they all are acute and that makes this trinagle an acute triangle. So cute! :)

Have a great day!!

Answer:

P(72 ≤ x ≤ 400) = 0.82. Correct: C.

Explanation:

Probability Distribution

In any probability distribution, the total probability of the sample space must be 1.

Since the sample space is given as a random variable x that takes values from 0 to 400, then:

P(0 ≤ x ≤ 400) = 1

For any value of x:

If the sample space is divided into two parts like:

P(0 ≤ x ≤ 72) and P(72 ≤ x ≤ 400), then the combined probability must be 1:

P(0 ≤ x ≤ 72) + P(72 ≤ x ≤ 400) = 1

Or, equivalently:

P(72 ≤ x ≤ 400) = 1 - P(0 ≤ x ≤ 72)

P(72 ≤ x ≤ 400) = 1 - 0.18

P(72 ≤ x ≤ 400) = 0.82

A. The value 0.92 is not correct since does not match with the value 0.82.

B. The value 0.18 is not correct since does not match with the value 0.82.

C. This is the correct value. Correct Choice

D. The value 0.982 is not correct since does not match with the value 0.82.

The solutions of the given linear equations are:  x = 7, - 13; x = 6, - 7; x = 5, - 9, respectively.

A linear equation is an equation that has on or multiple variables with the highest power of the variable is 1.

Given equations are:

1. |3x + 9| = 30

⇒ ( |3x + 9| )² = (30)²

⇒ 9x² + 54x + 81 = 900

⇒ 9x² + 54x + 81 - 900 = 0

⇒ 9x² + 54x - 819 = 0

⇒ 9(x² + 6x - 91) = 0

⇒ (x² + 6x - 91) = 0

⇒ (x + 13)(x - 7) = 0

⇒ x = 7, - 13

2. |2x+1| = - 13

⇒ (|2x+1|)² = (- 13)²

⇒ 4x² + 4x + 1 = 169

⇒ 4x² + 4x - 168 = 0

⇒ 4(x² + x - 42)= 0

⇒ (x² + x - 42)= 0

⇒(x - 6)(x + 7) = 0

⇒ x = 6, - 7

3. |x + 2| + 4 = 11

⇒ |x + 2| = 7

⇒ (|x + 2|)² = 7²

⇒ x² + 4x + 4 = 49

⇒ x² + 4x - 45 = 0

⇒ (x - 5)(x + 9) = 0

⇒ x = 5, - 9

Using the volume of a rectangular prism, it is found that Marcus shipped 2040 in³ of the boxes.

The volume of a rectangular prism of lenght l, width w and height h is given by:

V = lwh.

Prism 1 has dimensions of h = 10, l = 20, w = 7, hence it's volume in cubic inches is given by:

V1 = 20 x 10 x 7 = 1400 in³.

Prism 2 has dimensions of h = 4, l = 20, w = 4, hence it's volume in cubic inches is given by:

V2 = 20 x 4 x 4 = 320 in³.

Marcus shipped 1 of the larger boxes and 2 of the smaller boxes, hence the total volume is of:

V = V1 + 2V2 = 1400 + 2 x 320 = 2040 in³.

Answer:

2x+8/x^2-x-6

Step-by-step explanation:

=x^2+4x-1x-4

=(x-1)(x+4)

=x^2+2x+2x+4

=(x+2)(x+2)

=x^2-3x-1x+3

=(x-1)(x-3)

= (x-1)(x+4)/(x+2)(x+2) x 2x (x+2)/(x-1)(x-3)

= (x+4)(2)/(x+2)(x-3)

= 2x+8/x^2-x-6

Restrictions:

3m + 8 = 15 is not a quadratic equation. quadratic equation must have the power of 2 in the quadratic term.

Answer:

Definitely not.

Step-by-step explanation:

3m+8=15

A quadratic equation needs to consist of these values:

x^2+x+y

In this case x can be followed by any coefficient but needs to end with a variable to the power of 2. The second part of this question needs to have that variable- but to no power. Finally, the third part is just a regular integer. We can tell 3m+8=15 is not a quadratic because while it has a variable and integer, it does not have a variable to the power of two.

Answer:

116 cm²

Step-by-step explanation:

area shaded = total area - area not shaded

πr² is the area of a circle

total area = πr² = π*(6.5cm)² = 132.732289614 cm²

area not shaded = πr² (note the radius is 2.3cm for the non-shaded portion) = π*(2.3cm)² = 16.6190251375 cm²

area shaded = total area - area not shaded = 132.732289614 cm² - 16.6190251375 cm² = 116.113264476 cm² ≈ 116 cm²

Answer:

The sum of interior angles of a triangle is 180°

In a right triangle, one of the three angles is 90°.  Therefore, the sum of the other two angles is 90°.

Let a = one unknown angle

Let b = the other unknown angle

As the sum of the angles is 90°:

⇒ a + b = 90°

As the difference between the two angles is 20°:

⇒ a - b = 20°

Rewriting the first equation to make a the subject:

⇒ a = 90° - b

Substituting this into the second equation and solving for b:

⇒ 90° - b - b = 20°

⇒ 90° -2b = 20°

⇒ 70° = 2b

⇒ b = 35°

Substituting found value for b into  a = 90° - b  and solving for a:

⇒ a = 90° - 35°

⇒ a = 55°

Therefore, the two unknown angles are 35° and 55°

Answer:

q=13

Step-by-step explanation:

First, you can multiply to distribute 2 over -9 and 4.

-18=2(-q+4)

-18=-2q+8

Then, you can subtract 8 from both sides.

-18=-2q+8

-26=-2q

Finally, you can divide -2 on both sides.

13=q

Now, you can check by plugging in 13 for the value of q in the original equation.

-18=2(-(13)+4)

-18=2(-13+4)

-18=2(-9)

-18=-18

Hope this helps you! :)
