QUESTION: Solve and graph for x and y.

Answer:

? = 70°

Step-by-step explanation:

180 - 120 = 60°   (120° and 60° are supplementary angles)

180 - 50 - 60 = 70° (all triangle interior angles total 180°)

Answer:

pervious prices is $4.8 per pound

Step-by-step explanation:

current price is $6 per pound

previous price is 20% less than current price

20% of 6

6 × 20 ÷ 100 = $1.2

$6 - $1.2 = $4.8

Answer:

{-8, -4}

Step-by-step explanation:

Rewrite this function y=x2 +12x +32 as y = x^2 + 12x + 32; " ^ " indicates exponentiation.

Set this x^2 + 12x + 32 equal to zero (to find the zeros):  

x^2 + 12x + 32 = 0.  Let's solve this using the quadratic formula, which applies when ax^2 + bx + c = 0:

       -b ± √(b^2 - 4·a·c)

x = -------------------------------

                    2a

The coefficients of the given quadratic are {1, 12, 32}.  Thus, the discriminant is

b^2 - 4ac, or 12^2 - 4(1)(32), or 144 - 128, or 16. Therefore, we have:

       -12 ± √16                                                     -12 ± 4

x = --------------------    which simplifies to:    x = --------------- = { -8, -4}

              2                                                                  2

The zeros are {-8, -4}

Answer:

4.71 m

Step-by-step explanation:

Using cosine rule,

[tex]x {}^{2} = 2 {}^{2} { + 3 {}^{} }^{2} - 2(2)(3) \cos(140) \\ x = \sqrt{13 - 12 \cos(140) } \\ x = 4.71m[/tex]

Answer:

Well there if you look at the choices given its only 4.71 and 8.52. According to the model is looks like we need to find the hypotnuse which is the longest lightning of any triangle. But here’s the thing, in every triangle if you add the two legs, the sum of that number has to be GREATER then the hypotnuse or it wouldn’t stick. If your dd 2+3 together you get 5. Only the last option is greater then 5. The final answer is 8.52.

Remeber, you CAN’T use the Pythagorean theroum on any triangle with out a 90 degree angle. Pythagorean Theorem only works for right triangles. This is why the first option is given to trick you.

Answer:

6x and 1x or x

Step-by-step explanation:

the highest common factor of 6x and 66xy in 6x

6x ÷ 6x = 1

66xy ÷ 6x = 11y

the lowest common factor of 6x and 66xy is 1x or x

6x÷ 1x =6

66xy÷ 1x = 66y

6x÷ x = 6

66xy ÷ x = 66y

NOTE

1x and x is the same

Answer:

it takes the bears 12 days to eat honey together.

Step-by-step explanation:

1/x+9+1/x+16=1/x

(solve this using cross multiplication)

= x^2 = 144

x=12

answer: 12

explanation:

let x=two bears eating honey together

let x+9=first bear

let (x+9)+7=second bear     **because we know the second day takes 7 more days to eat the same amount of honey as the first bear**

since the bears can finish a barrel of honey over multiple days, they can only finish part of the barrel of honey in one day.

therefore...

x/(x+9)+x(x+16)=1 or x*1/(x+9)+x*1/(x+16)=1     **the equation equals 1 because you are trying to find how much honey they eat in one day aka 1=single day**

if you solve, you get x=-12; x=12. it can only be the positive value so x=12 is your answer. your welcome fellow rsm students.

The area for the given dimensions of Jared's classroom is, 64 m²

An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².

Given that,

The dimensions of Jared's classroom are,

12 m, 4 m, 6 m, 4 m, 2 m, 8 m

we can divide the area of classroom in two parts,

first A₁, having side lengths of 6 m & 8 m

second A₂, having side lengths of 4 m & 4 m

Jared's classroom area =  A₁ +  A₂

A₁ = 6 × 8

      =  48

A₂ = 4 × 4

     = 16

A =  A₁ +  A₂

  = 16 + 48

  =  64

The area of classroom is 64 m²

The given figure consists of rectangular and triangular prisms. The birdseed that it will take to fill Sharri’s birdhouse completely is 5100

The given figure consists of rectangular and triangular prisms. The volume of the prism is expressed as:

Volume of the rectangular prism = lwh
Vr =10 * 15 *30
Vr = 4500 square cm

For the triangular prism

Vt = BH

B = 0.5 * 4 * 15
B = 30 square units

H = 20cm

Vt =20 * 30
Vt = 600 square units

Total volume = 4500 + 600 = 5100

Hence the birdseed that it will take to fill Sharri’s birdhouse completely is 5100

Answer:

D. There is no evidence to show an increase in the proportion of students attending college because the p-value is less than the alpha level, therefore we will reject the null hypothesis.

Step-by-step explanation:

Assuming a significance level of α=0.05, since 0.000548<0.05, we reject the null hypothesis and conclude that there is no evidence to show an increase in the proportion of students attending college. So option D is correct.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

mpho is the 50th fastest and slowest runner in her school.

Now,

Since, mpho is the 50th fastest and slowest runner in her school.

Hence, Total number of students = (50 + 50) - 1

                                                   = 100 - 1

                                                   = 99

Thus, There are 99 students in her school.
