which expression has the fewest number of significant figures?

a. 360
b. 18.3
c. 296.54
d. 5,280

Answer:

x = 4

y = 2

Step-by-step explanation:

the third angle of the triangle

180 - (148 + 18) = 14º

Therefor

3x + y = 14

5x - y = 18

Add the equations

8x = 32

Divide both sides by 8

x = 4

Plug in x = 4

3(4) + y = 14

12 + y = 14

y = 2

9514 1404 393

Answer:

  (x, y) = (4, 2)

Step-by-step explanation:

The triangles are similar by AA similarity, so the corresponding angles are congruent.

  5x -y = 18 . . . . . . unmarked angles are congruent

  18 +(3x+y) +148 = 180 . . . . . sum of angles in a triangle is 180°

__

After subtracting 166 from both sides, the second equation simplifies to ...

  3x +y = 14

Adding this to the first equation gives ...

  8x = 32

  x = 4 . . . . . . divide by 8

Then substituting for x in the first equation gives ...

  5(4) -y = 18

  20 -18 = y = 2

The values of the variables are x = 4, y = 2.

The angle marked with a double mark is 14°, given by the simplified second equation.

Answer:

4.57

Step-by-step explanation:

square root of 65.71 divided by pie

Step-by-step explanation:

→ 70 = 19 - 3x

→ - 19 + 70 = -3x

→ 51 = -3x

→ -3x = -51

→ x = -51/3 = -17

→ x = -17

therefore, value of x is -17.

Answer:

Step-by-step explanation:

-39 = 18 + 4m

4m + 18 = -39

Subtract 18 from both sides

4m = -39 - 18

4m = -57

Divide both sides by 4

m = -57/4

47%

Step-by-step explanation:

.375 × .125 = .046875

rounding up, 5 keeps the 7 as is, 7 is greater than 5, therefore the 8, becomes a 9, 9 is greater than 5, so the 6 becomes a 7, .047.

move the decimal three digits to the left and you get, 47%.

It takes 6 hours to reach the destination when traveling at 388 mph.

Speed is the ratio of total distance traveled to the total time taken It is given by:

Speed = distance/time

Given that it takes 4 hours to reach a destination when travelling at 582mph, hence the distance is:

582 = distance / 4

distance = 2328 miles

If travelling at 388 mph, the time is:

388 = 2328 / time

time = 6 hours

Hence it takes 6 hours to reach the destination when traveling at 388 mph.

Answer:

I believe, that they are parallel because they both have 90° angles meaning that the other angle has to be 90° as well. I dont really know how to explain it but they are both in the same position and have 90° angles im not the best with these. •So im not exactly sure if this is correct though.

-They also have corresponding and congruent angles that do match up, so yes they are parallel to eachother

Answer:

[tex]\sf f^{-1}(x) = \dfrac{x}{2}+4[/tex]

Step-by-step explanation:

A function is given to us and we need to find the inverse of the function in slope intercept form . The given function is ,

[tex]\sf\implies f(x) = 2x - 8 [/tex]

Let us assume that y = f(x) , so that ,

[tex]\sf\implies y = 2x - 8 [/tex]

Now interchange the positions of x and y , we have ,

[tex]\sf \implies x = 2y - 8[/tex]

Solve for y in terms of x ,

[tex]\sf \implies 2y = x + 8 \\\\\sf\implies y =\dfrac{x}{2}+4 [/tex]

This is the inverse of the function in slope intercept form. Now we can replace this y with f-¹(x) , as ,

[tex]\sf \implies \boxed{\pink{\frak{f^{-1}(x) = \dfrac{x}{2}+4}}}[/tex]

Answer:

$18

Step-by-step explanation:

378 ÷ 27 = 14

14 + 4 = 18

The normal cost per person = $18

The normal cost per person is $18.

Given,

Brad's science class is heading to Skylight Observatory on a field trip.

The observatory offers a group rate for students that is $4 less per person than the normal cost.

There are 27 students in Brad's science class.

The total cost for the class is $378.

We need to find the normal cost per person.

We divide the total cost by the number of items.

Example:

7 bags cost $49

1 bag cost = $49 / 7 = $7

We have,

The number of students = 27

The total cost of the class trip with the offer =  $378

Offer = $4 less than the normal cost per student

Now,

The offer cost for each person:

= $378 / 27

= $14

The normal cost for each person:

= $14 + $4

= $18

Thus the normal cost per person is $18.

Answer:

152558.75*5%=7627.9

Step-by-step explanation:

Answer:

a. 53.68

b. 53.53

Step-by-step explanation:

a. Step 1: Approximate the value for [tex]\sqrt{62}[/tex]:

Since [tex]\sqrt{62}[/tex] is close to [tex]\sqrt{64}[/tex] (which is 8), this value can be approximated as a number that is less than but very close to 8. I chose 7.9.

The expression becomes 6(7.9)+2π

Step 2: Approximate the value for 2π

Since π is approximately 3.14, 2π is approximately 6.28.

The expression becomes 6(7.9)+6.28

Step 3: Use order of operations

6(7.9)+6.28=47.4+6.28=53.68

b. Step 4: If allowed, use a calculator to check how close your approximation is to the actual value

[tex]6\sqrt{62} +2\pi =53.5272[/tex]

The approximation 53.68 is decently close to the actual value, so no minor math errors were made.

Answer:

54     and 53.53  see below

Step-by-step explanation:

Estimate the square root first.  7x7 = 49  and 8x8=64 so you can use 8 for your estimate.  You can also estimate Pi as 3.

Now you have:

(6 x 8) + 2(3)   which is 48 + 6 = 54

Using your calculator you get

47.244 + 6.283 = 53.53  rounded to the nearest hundredth

Answer:

No solution

Step-by-step explanation:

5x−4≥12 AND 12x+5≤−4

solve it separately

5x - 4>=12

add 4 on both sides

5x >= 16

Divide both sides by 5

x > = 16/5

12x+5≤−4

subtract 5 from both sides

12x <= -9

divide both sides by 12

x<= -9/12

x<=-9/12   and x>= 16/5

Remember y=mxb?

m is slope and b is y-intercept

so y=2/7x-9

Remember that slope is RISE/RUN so for every 2 squares that you go up, you go 7 squares to the right.

Also remember that since your graph is going thru your Cartiesian Plane in quadrent 4, your y value in your ordered pairs will most probably be a negative.
