0.38
How many times was the game won that day?

Answer:

x = 136, y = 144

Step-by-step explanation:

x+y = 280

y = x +8

use substitution

x + x+8 = 280

2x = 272

x = 136

y= 136+8 = 144

Answer:

the answer is x=136

Step-by-step explanation:

x + y = 280

x + 8 = y (substitute this expression for y)

x + (x + 8) = 280

2x + 8 = 280

2x = 272 -> x = 136

to find y:

x + 8 = y

136 + 8 = y

144 = y

CHECK:

136 + 144 = 280

yes

Answer:

X = 5 u

m∠4 = 85º

m∠ = 85º

Step-by-step explanation:

17x = 9x + 40

17x-9x = 40

8x = 40

x = 40/8

x = 5

m∠4 = (17x)º = (17*5)º = 85º

m∠ = (9x+40)º = (9*5 + 40)º = (45 + 40)º = 85º

A .........................

Answer:

Value of x = 87°

Step-by-step explanation:

Given:

∠1 = 102°

∠2 = x + 15°

Find:

Value of x

Computation:

We know that, given two lines are parallel and third line interest that

So,

Corresponding angles are equal

So,

∠1 = ∠2

x + 15 = 102

x = 87

Value of x = 87°

Answer:

Step-by-step explanation:

To solve this problem, isolate the value of x from one side of the equation.

First, switch sides.

-29=x+8

x+8=-29

Then, subtract by 8 from both sides.

x+8-8=-29-8

Solve.

-29-8=-37

x=-37

Therefore, the final answer is x=-37.

Answer:

  B, C, E

Step-by-step explanation:

Distributing the minus sign in the given expression results in ...

  6x +1 -3x -(-1)

  6x +1 -3 +1 . . . . simplify

The two expressions that show the constant terms as +1 - 1 are erroneous. The two constant terms are +1 -(-1) or +1 +1.

The correct expressions are the 2nd, 3rd, and 5th ones (b, c, e).

Answer:

2100 second

Step-by-step explanation:

4:30 pm to minutes

4 × 60 + 30 = 240 + 30

= 270 minutes

5:05 to minutes

5 × 60 + 5 = 300 + 5

= 305

4:30 to 5:05

305 - 270

= 35 minutes

35 minutes to second

35 × 60

= 2100 second

Answer:

2100

Step-by-step explanation:

25 minutes you need to know that 60 sec =1 hour.35x60=2100

Velocity=226mph

Angle made with horizontal= 18°

The vector components would be [tex] 226~sin18° \hat{j} + 226~cos18° \hat{i} [/tex]

The vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°

What is a Vector ?

An parameter that has both magnitude and direction is called a vector.

It is given that

Speed S = 226 mph

Angle = 18 degree with the horizontal

The vector component are

[tex]\rm v_x , v_y[/tex]

here these are x and y components of the vector

V is the magnitude = |v| = 226

The vector component is given by

cos [tex]\rm \theta[/tex] = [tex]\rm v_x[/tex] / |v|

[tex]\rm v_x[/tex] = 226 cos 18°

[tex]\rm v_y[/tex] = 226 sin 18°

Therefore the vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°

Answer:

B

Step-by-step explanation:

first of all we have to multiply 9√3 for each members in the brackets. For do this we have to multiply number x number and roots x roots

(9x8) = 72

(√3)^2 = 3

72 x 3 = 216

9 x 9 = 81

√3 x √5 = √15

81√15

now we have to added up the two results

216 + 81√15

Answer:

71.549

Step-by-step explanation:

Answer:

The sum of 50.249 + 21.3 is 71.549.

Step-by-step explanation:

50.249 + 21.3 can be written as (50 + 20) + (0 + 1) + (0.2 + 0.3) + 0.049, which makes calculating the sum easier. 50 + 20 = 70, 0 + 1 = 1, 0.2 + 0.3 = 0.5, and you still have a 0.049. Add the numbers all together and you'll get that the sum of 50.249 and 21.3 is 70 + 1 + 0.5 + 0.049 or 71.549.

Answer: N(t) = (2^t)*1500

Step-by-step explanation:

Let's define the hour "zero" as the initial population.

So if N(t)  is the number of bacteria after t hours, then:

N(0) = 1500.

Now, we know that the population doubles every hour, so we will have that after one hour, at t = 1

N(1) = 2*1500 = 3000

after two hours, at t = 2.

N(2) = 2*(2*1500) = (2^2)*1500

After three hours, at t = 3

N(3) = 2*(2^2)*1500 = (2^3)*1500

So we already can see the pattern, the number of bacteria after t hours will be:

N(t) = (2^t)*1500

Answer:

10 hours

Answer:

27 m

Step-by-step explanation:

The position of a body is given by :

[tex]s=t^3 - 12t^2 + 36t[/tex]

We need to find the total distance traveled by the body from t=0 to t=3.

At t = 0,

[tex]s=0^3 - 12(0)^2 + 36(0)=0\ m[/tex]

At t = 3 s,

[tex]s=(3)^3 - 12(3)^2 + 36(3)\\\\=27\ m[/tex]

So, the total distance from t=0 to t=3 is equal to 27 m.
