HELP ASAP PLZ What value of d makes the equation (3d – 2) = }(d + 5) true?​

Answers

Answer 1

1 Remove parentheses.

3d-2=d+5

2 Add 22 to both sides.

3d=d+5+2

3 Simplify  d+5+2  to  d+7.

3d=d+7

4 Subtract d from both sides.

3d-d=7

5 Simplify  3d-d to  2d.

2d=7

6 Divide both sides by 2.

7/2=d

7 Flip sides.

d=7/2

(Optional decimal form)

d=3.5

So 7/2 or 3.5

can a pentagon have interior angles that measure 120°, 105°, 65°, and 95°? explain.

Answers

Answer:

No

Step-by-step explanation:

because firstly, pentagon is five sided figure and secondly, the sum of interior angled of a pentagon is 540°

No, the given angles can not be the measure of the pentagon angles.

What is the pentagon?

A pentagon is a polygon having five sides connected to each other to form a closed figure. The sum of the angles of the pentagon is equal to 540 degrees.

Given angles are 120°, 105°, 65°, and 95°. Here as we know that the pentagon is a polygon having five sides. The number of angles formed by all the sides of the pentagon is also five.

Here we have only four angles that are 120°, 105°, 65°, and 95°. But to form a pentagon there must be five angles and the sum of the angles should be 540 degrees.

Therefore, the given angles can not be the measure of the pentagon angles.

Using the inverse of the sine function, it is found that the value of x is:

[tex]x = -\frac{\pi}{6}[/tex]

What is the inverse sine function?

It is the function described by:

[tex]y = \arcsin{x}[/tex]

And means that sine of y is equals to x, that is:

[tex]x = \sin{y}[/tex]

In this problem, the function is:

[tex]x = \arcsin{-\frac{1}{2}}[/tex]

Which means that we have to solve for x, considering that the sine of x is of -1/2. Hence:

[tex]\sin{x} = -\frac{1}{2}[/tex]

[tex]x = -\frac{\pi}{6}[/tex]

Hence, the value of x is given by:

[tex]x = -\frac{\pi}{6}[/tex]

Each deli sandwhiches made uses 8/8 pound of roast beef.Marisa started with 5 pounds of roast beef and now has 2 3/4 pounds left. How many del sandwhiches did she make

Answers

Answer:

Marisa has made 6 sandwiches.

Step-by-step explanation:

The pounds of roast beef required to make each sandwiches is [tex]\frac{3}{8}[/tex], and not [tex]\frac{8}{8}[/tex] as erroneously typed in the question.

Given that each deli sandwiches made, uses [tex]\frac{3}{8}[/tex] pounds of roast beef.

Marisa started with 5 pounds, and had 2[tex]\frac{3}{4}[/tex] pounds left.

Thus,

pounds of roast beef used = 5 - 2[tex]\frac{3}{4}[/tex]

                                             = 5 - [tex]\frac{11}{4}[/tex]

                                             = [tex]\frac{20 - 11}{4}[/tex]

                                             = [tex]\frac{9}{4}[/tex]

                                             = 2[tex]\frac{1}{4}[/tex]

Marisa had used 2[tex]\frac{1}{4}[/tex] pounds of roast beef. So that;

the number of del sandwiches made = 2[tex]\frac{1}{4}[/tex] ÷ [tex]\frac{3}{8}[/tex]

                                                    = [tex]\frac{9}{4}[/tex] ÷ [tex]\frac{3}{8}[/tex]

                                                    = 6

Therefore, the number of sandwiches made by Marisa is 6.

c) uv = 1.71 and vu = 1.33
d) uv = 1.71 and vu = 3.16

Answers

Answer:

D. uv = 1.71 and vu = 3.16

Step-by-step explanation:

The scalar projections are uv = 1.71 and vu = 3.16

The correct option is (D)

What is meant by scalar projection?

The definition of scalar projection is the length of the vector projection.

Given: u = ⟨2, 1⟩,  = ⟨4, –1⟩, and θ = 40°

Proj u_v = |u| cosθ

= 2.25 * cos 40

= 2.25 * 0.7660

=1.72

and, Proj v_u = |v| cosθ

= 4.123 * cos 40

= 4.123 * 0.7660

= 3.16
