Answer:

False

Step-by-step explanation:

I would say false. The operations inside should always go by PEMDAS unless instructed otherwise

Answer:

FALSE

Step-by-step explanation:

Within a set of parentheses, the order of operations should be followed. This is because you will get the wrong answer if you don't.

Answer: 3km/h

Step-by-step explanation:

15km per 5h, which is 3km per 1h. This is pretty easy. I don't know what you want for her average speed like in unit (e.g 1 hour). If you are asking for the hour unit it is 3km/h

Answer:

Perimeter = 271 meters

Step-by-step explanation:

third angle measure would have to be 180 - 122 = 58 degrees

you can use the law of sines:

sin 58° = sin 74°

   90           b

.85 = .96

 90       b

cross-multiply:  .85b = 86.4

                          b = 102

now do again to find third side:

sin 58° = sin 48°

   90           c

.85 = .74

 90       c

.85c = 67

c = 79

now you know all 3 sides so add them to get perimeter (79+102+90) = 271

Answer:

B

Step-by-step explanation:

x=2

3x + 10

3(2) + 10

6+10

16

Db=16

16(x)

16(2)

32=AE

Db=16, 32=AE which is B

plz brainliest

Answer:

16, 32

Step-by-step explanation:

BD is midsegment of the ΔACE ⇒ 16x = 2(3x + 10)

16x - 6x = 20 ⇒ x = 2

BD = 3(2) + 10 = 16 units

AE = 16(2) = 32 units

Answer:

[tex]7(2x + 3) = 3(4x + 6) + 2x + 3 \\ 14x + 21 = 12x + 18 + 2x + 3 \\ 14x - 14x = 21 - 21 \\ 0 = 0[/tex]

Hey there!

Here is a graph of the points:

A scatterplot is a graph, but the points won't be able to connect in a straight line, and they have no relation.

A line of best fit is a line that goes evenly through the points, or as best as it could.

Answer:

x^2 + 16x + 60 = 0

Step-by-step explanation:

Add 16x to both sides of the given equation.  We get x^2 + 16x + 60 = 0.

Answer:

  (c)  16πx^6y^10

Step-by-step explanation:

The applicable rules of exponents are ...

  (ab)^c = (a^c)(b^c)

  (a^b)^c = a^(bc)

__

Putting the expression for r in the formula, you have ...

  A = πr^2

  A = π(4x^3y^5)^2 . . . . . substitute for r

  A = π(4^2)(x^(3·2))(y^(5·2)) = 16πx^6y^10

Answer:

x=30° y=5

Step-by-step explanation:

All sides of the top triangle are equal. And all angles are equal Since it's an equilateral triangle.

so

8y=40

y=40/8

y=5

Since it's an equilateral triangle. All angles are equal And each angle has dimensions

=180°/3=60°

The angle of the straight line = 180°

so The obtuse angle of the lower isosceles triangle is 180°-60°=120°

The angles at the base of the isosceles triangle are equal

so 2x° = 180°-120°

2x°=60°

x°=60°/2

x°=30°

Answer:

x + 5

Explanation:

x^2 + 3x − 10 /x−2  

=  x^2 + 3x − 10 /x − 2

=  (x−2)(x+5) /x−2

= x + 5

Answer:

A

Step-by-step explanation:

earning $10 an hour because it increases by 40

Answer:

Z PTS = 90°

or, Z PTS = Z PTR + Z PTS

or, 90° = x° + ( 2x - 57 )°

or, 3x° = 90° + 57°

or, 3x° = 147°

or x° = 49°

ans: Z PTR = Z UTV = 49°

Z STU = 180°

or, Z UTV + Z STV = 180°

or, 49° + Z STV = 180 °

or, Z STV = 180° - 49°

= 131°

ans : Z STV = 131°

Answer:

Step-by-step explanation:

cot θ=11

tan θ=1/11

[tex]\sin ~2\theta=\frac{2 \tan ~\theta}{1+\tan^2 \theta} =\frac{2*\frac{1}{11} }{1+(\frac{1}{11} )^2}=\frac{22 }{122} \\\\cos~2 \theta=\frac{1-tan^2 \theta}{1+tan^2\theta} =\frac{1-(\frac{1}{11})^2 }{1+(\frac{1}{11} )^2} =\frac{120}{122} =\frac{60}{61} \\tan 2 \theta=\frac{2 tan\theta}{1-tan^2 \theta} =\frac{2*(\frac{1}{11 } )}{1-(\frac{1}{11} )^2} =\frac{2*11}{120} =\frac{11}{60}[/tex]

Answer:

Work individually or in teams of two to construct and launch paper rockets using a teacher-built PVC-pipe launcher.

Following the flight of their rocket, calculate the altitude their rocket achieved.

Based on the flight performance of their rockets, analyze their rocket designs, modify or rebuild them, launch again, and calculate the altitude achieved to determine if their changes affected the performance of the rocket.

Conclude the activity by writing a post-flight mission report.
