Answer:

D.) The company cannot provide lunch for all 20 employees and use the entire budget because there is no solution to the system of equations r+t=20 and 5r+5t=150

Step-by-step explanation:

The given information says that the total amount of lunch bought should equal $150 when both options cost $5:

[tex]5r+5t=150[/tex]

It also says that the food should feed all 20 employees:

[tex]r+t=20[/tex]

This is now a system. Solve by substitution.

Solve the second equation for r. Use inverse operations to isolate the variable by subtracting t from both sides:

[tex]r+t-t=20-t\\\\r=20-t[/tex]

Now insert this value of r into the first equation:

[tex]5(20-t)+5t=150[/tex]

Simplify the equation. Use the distributive property:

[tex]5(20)+5(-t)+5t=150\\\\100-5t+5t=150[/tex]

Cancel the terms:

[tex]100\neq 150[/tex]

100 does not equal 150, so there is no solution to the system.

Answer:

  (D)  (170 -4x)°

Step-by-step explanation:

Angles 1 and 5 are corresponding, so are congruent. Angle 6 forms a linear pair with angle 5, so is its supplement. That is, angle 6 is the supplement of angle 1:

  ∠6 = 180° -(4x +1)° = (180 -1)° -4x°

  ∠6 = (179 -4x)° . . . . matches choice D

The answer is 5 11/12.

You have to add 3 1/4 AND 2 2/3.

3 1/4 + 2 2/3 =

add the whole numbers FIRST.

2 + 3 = 5

Now add the fractions

1/4 + 2/3 = 11/12.

Now add both of the numbers

5 + 11/12 = 5 11/12

divide.

-25/176 is -.142

Answer:

you divide -25 by 176

-25 on the inside of the "dog house" and 176 on the outside because if you did it the other way it would be a whole number.

It would equal -0.14204545454

Answer:

[tex]\mathrm{Factor}\:x^2+5x+6:\quad \left(x+2\right)\left(x+3\right)[/tex]

Step-by-step explanation:

Let us assume the trinomial of the form [tex]x^2+bx+c[/tex]

[tex]x^2+5x+6[/tex]

Break the expression into the groups

[tex]=\left(x^2+2x\right)+\left(3x+6\right)[/tex]

Factor out 'x' from [tex]x^2+2x[/tex]

i.e.

[tex]\:x^2+2x=x\left(x+2\right)[/tex]

Factor out '3' from 3x+6

i.e.

3x+6 = 3(x+2)

so the expression becomes

[tex]\:x^2+2x=x\left(x+2\right)[/tex]

[tex]\mathrm{Factor\:out\:common\:term\:}x+2[/tex]

[tex]=\left(x+2\right)\left(x+3\right)[/tex]

Hence,

[tex]\mathrm{Factor}\:x^2+5x+6:\quad \left(x+2\right)\left(x+3\right)[/tex]

Answer:

length=4

Width=2×4-3=5

Step-by-step explanation:

Let length =X

Width =2x-3

Perimeter=18

2(length+width)=18

2(X+2x-3)=18

3x-3=9

3x=12

X=12/3

X=4

So length=4

Width=2×4-3=5

[tex] \boxed{ \sf{Perimeter \: of \: a \: rectangle = 2(L + W)}}[/tex]

Plug the values and solve for L

➺ [tex] \sf{18 = 2(L+ 2L - 3)}[/tex]

➺ [tex] \sf{18 = 2(3L - 3)}[/tex] { Add : 2L and L )

The description that matches the inequality x < 1 is:

All the points to the left of x = 1 are part of the solution, and there is an open interval at x = 1.

The values that are less than a number a in the number line are the values to the left of a.

Hence, for the inequality x < 1, we have that:

All the points to the left of x = 1 are part of the solution

Additionally, since the inequality signal is < and not ≤ 1, x = 1 is not part of the inequality, meaning that there is an open interval at x = 1.

Answer:

Area of whole circle, i.e. 360 degrees = π(8.91)(8.91) = 79.3881 sq. cm

Area of 1 degree = 0.2205225 sq.cm.

Area of 81 degrees = 17.8623225 sq.cm.

The area of the shaded sector is about 16.77 cm2.

We are given that;

The radius=8.91

Now,

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.

When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.

Thus, we have:

[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]

That ∑ sign shows "sum"

To find the area of the shaded sector, we need to use the formula:

[tex]$A = \frac{\theta}{360} \times \pi r^2$[/tex]

where [tex]\theta[/tex] is the central angle in degrees, and r is the radius of the circle.

Plugging in the given values, we get:

[tex]$A = \frac{81}{360} \times \pi (8.91)^2A \approx 16.77 \text{ cm}^2$[/tex]

Therefore, by the area answer will be 16.77 cm2.
