Answer:

x=30 ; y=60 ; z=120.

Step-by-step explanation:

(we can solve it in a system.)

z+2x=180 => z=180-2x
y+4x=180 => y=180-4x

y+z=180

4x+2x=180 => 6x=180 => x=30

<=>

z=180-2*x=180-2*30=180-60=120

y=180-4x =180-4*30=180-120=60

Answer:

x=\frac{64}{5}=12\frac{4}{5}

Step-by-step explanation:

1. Simplify the expression

\frac{-1}{4}\cdot\left(x+\frac{12}{3}\right)=\frac{+\left(-21\right)}{5}

Find the greatest common factor of the numerator and denominator:

\frac{-1}{4}\cdot\left(x+\frac{\left(4\cdot3\right)}{\left(1\cdot3\right)}\right)=\frac{+\left(-21\right)}{5}

Factor out and cancel the greatest common factor:

\frac{-1}{4}\cdot\left(x+4\right)=\frac{+\left(-21\right)}{5}

Multiply the fractions:

\frac{\left(-1\cdot\left(x+4\right)\right)}{4}=\frac{+\left(-21\right)}{5}

Expand the parentheses:

\frac{\left(-x-4\right)}{4}=\frac{+\left(-21\right)}{5}

Break up the fraction:

\frac{-x}{4}+\frac{-4}{4}=\frac{+\left(-21\right)}{5}

Find the greatest common factor of the numerator and denominator:

\frac{-x}{4}+\frac{\left(-1\cdot4\right)}{\left(1\cdot4\right)}=\frac{+\left(-21\right)}{5}

Factor out and cancel the greatest common factor:

\frac{-x}{4}-1=\frac{+\left(-21\right)}{5}

For the box plot of Sam, the data is symmetric and shows that half of the assignments contained 15 problems or fewer.

Box plot is the way of representation of data which gives the graphical image of the data set to understand better.

The minimum and the maximum values in the box plot is plotted at the end points.

For the box plot which Sam used to keep the track,

For the given box plot the data is symmetric, and the medium of the box plot is 15. Thus, the half of the math assignment have less than 15 problem and half of them has more than 15 problems.

Thus, for the box plot of Sam, option A is correct which is, the data is symmetric and shows that half of the assignments contained 15 problems or fewer.

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

The polynomials are shown below.

[tex]\rm (2x^4 +x^3-4x^2 +3)\ and \ (4x^4-2x^3-x^2 +10x +2)[/tex].

We have to find the addition of the polynomials.

Answer:

scalene acute

Step-by-step explanation:

Since the 3 sides are unequal and the 3 interior angles are less than 90° it is scalene acute

Answer:

Scale acute

Step-by-step explanation:

Hi there!

This is a scalene triangle, meaning that none of the sides have the same length.

Because all of its interior angles are acute, meaning that they all measure less than 90 degrees, this is an acute triangle.

Therefore, this is a scalene acute triangle.

Answer:

80.78°

Step-by-step explanation:

When the 30 cm long string will be bent in the form of a sector it's two sides will be radii of the sector and lower part be the arc. Length of the arc can be found as given below.

Length of the string = 30 cm

radius of sector (r)= 8.8 cm

Length of the arc (l) = 30 - 2*8.8 = 30 - 17.6 = 12.4 cm

Let the sector makes [tex]\theta[/tex] angle at the centre of the circle.

Formula for length of arc of a sector is given as:

[tex]\huge \red{l=\frac{\theta}{360\degree}\times 2\pi r}[/tex]

Plugging the values of l and r in the above formula, we find:

[tex]12.4 = \frac{ \theta}{360 \degree} \times 2(3.14)(8.8) \\ \\\implies12.4 = \frac{ \theta}{360 \degree} \times 55.264 \\ \\ \implies \: \theta = \frac{12.4 \times 360 \degree}{55.264} \\ \\ \implies \: \theta =80.775 \degree \\ \\ \implies \: \theta \approx \: 80.78 \degree[/tex]

The percent of the cost of the printer Carl paid is 16.45%

Since John, Carl and Jason each paid $15, $25, and $112 respectively, the total cost of the printer is T = $15 + $25 + $112 = $152

Since Carl paid $25, we need to find the percent of the total amount Carl paid.

So, percent Carl paid = amount Carl paid/total cost × 100 %

Since amount Carl paid = $25 and total cost = $152,

Substituting the values of the variables into the equation, we have

percent Carl paid = amount Carl paid/total cost × 100 %

percent Carl paid = $25/$152 × 100 %

percent Carl paid = 0.1645 × 100 %

percent Carl paid = 16.45%

The percent of the cost of the printer Carl paid is 16.45%
