Evaluate the following problem: (7.2 × 105)(0.4 × 10−3)

Answer:

x = 51

Step-by-step explanation:

These angles equal each other because they're vertical angles so:

2x + 8 = 110

2x = 110 - 8

2x = 102

x = 51

Answer:

x= 8 inches

Step-by-step explanation:

you left out the other lengths but since i had this same question once, the other lengths are 12 and 2-

dimensions of the box:

12 in x 2 in x ?

=272 square inches

and we know that there are 6 faces

area=  2 *(12 * 2) + 2 *(2*x) + 2 *(12*x)

area = 272 sq. in.  = 48 + 4x + 24x

272 = 48 + 28x

272 - 48 = 28x

224 = 28x

x = 8 inches

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

Answer:

x = 4

Step-by-step explanation:

7.5 + 7.5 = 15

[tex]\frac{x}{8}[/tex] = [tex]\frac{7.5}{15}[/tex]

cross multiply

15x = 60

divide

x = 4

or

since the bigger one is 2x smaller

8/2 = 4

Answer:

45

Step-by-step explanation:

5*3*3

5*3=15

15*3=45

1/3 Probability both are red

red picked first:

6/10

red picked second:

5/9 (9 as first red marble not replaced so 5 red marbles remaining and 4 blue marbles still)

6/10 * 5/10 = 1/3

Answer:

Mid point = (–1 , –1)

Step-by-step explanation:

From the question given above, the following data were obtained:

(1, –6)

(–3, 4)

x₁ = 1

x₂ = –3

y₁ = –6

y₂ = 4

Mid point = (X, Y)

X = (x₁ + x₂)/2

X = (1 + –3)/2

X = (1 – 3)/2

X = –2/2

X = –1

Y = (y₁ + y₂)/2

Y = (–6 + 4)/2

Y = –2/2

Y = –1

Mid point = (X, Y)

Mid point = (–1 , –1)

Answer:

it's 140 ÷ 2 = 70

bcz the XY is a Inscribed angle

Answer:

m∠LOM=48°

Step-by-step explanation:

∠LON=180° AND ∠LON=∠LOM+∠MON

⇒ 7x-92+6x+12=180

⇒13x=180+92-12

⇒x=20

m∠LOM=7x-92°=140°-92°=48°

Answer:

121 degrees

Step-by-step explanation:

Given

Radius r = 18ft

Length of the arc = 38ft

Required

angle of rotation

Using the formula

Length of an arc = theta/360 * 2πr

Substitute the given data

38 = theta/360 * 2π(18)

38 = theta/360 * 113.04

theta/360 = 38/113.04

theta/360 = 0.33616

theta = 0.33616 * 360

theta = 121.02

Hence the angle of rotation to the nearest degree is 121 degrees

Answer:

DIVIDE THE TWO ANWSER

Step-by-step explanation:

Answer:

Q (0,1) H (3,5) J (5,3)

Step-by-step explanation:

Anytime you rotate a shape around the origin, the numbers in the coordinates become their opposites.

(x,y) becomes (-x,-y).

So, (0, -1) becomes (0,1).

(-3,-5) becomes (3,5).

And, (-5, -3) becomes (5,3).

Answer: Here you go, hope this helps.

Step-by-step explanation:

Answer:  Part A: The y-intercept of the line of best fit is about 4. This represents the starting point, or figure 0.

Part B: Using the line, you could determine that the slope is about 3/2, or 1.5, and the 13th month would be at about 24 matches.

The guy above is right but a few tips

Step-by-step explanation:

Dont copy paste it in. Otherwise it wont count due to teachers

Answer:

(a) 100 fishes

(b) t = 10: 483 fishes

    t = 20: 999 fishes

    t = 30: 1168 fishes

(c)

[tex]P(\infty) = 1200[/tex]

Step-by-step explanation:

Given

[tex]P(t) =\frac{d}{1+ke^-{ct}}[/tex]

[tex]d = 1200\\k = 11\\c=0.2[/tex]

Solving (a): Fishes at t = 0

This gives:

[tex]P(0) =\frac{1200}{1+11*e^-{0.2*0}}[/tex]

[tex]P(0) =\frac{1200}{1+11*e^-{0}}[/tex]

[tex]P(0) =\frac{1200}{1+11*1}[/tex]

[tex]P(0) =\frac{1200}{1+11}[/tex]

[tex]P(0) =\frac{1200}{12}[/tex]

[tex]P(0) = 100[/tex]

Solving (a): Fishes at t = 10, 20, 30

[tex]t = 10[/tex]

[tex]P(10) =\frac{1200}{1+11*e^-{0.2*10}} =\frac{1200}{1+11*e^-{2}}\\\\P(10) =\frac{1200}{1+11*0.135}=\frac{1200}{2.485}\\\\P(10) =483[/tex]

[tex]t = 20[/tex]

[tex]P(20) =\frac{1200}{1+11*e^-{0.2*20}} =\frac{1200}{1+11*e^-{4}}\\\\P(20) =\frac{1200}{1+11*0.0183}=\frac{1200}{1.2013}\\\\P(20) =999[/tex]

[tex]t = 30[/tex]

[tex]P(30) =\frac{1200}{1+11*e^-{0.2*30}} =\frac{1200}{1+11*e^-{6}}\\\\P(30) =\frac{1200}{1+11*0.00247}=\frac{1200}{1.0273}\\\\P(30) =1168[/tex]

Solving (c): [tex]\lim_{t \to \infty} P(t)[/tex]

In (b) above.

Notice that as t increases from 10 to 20 to 30, the values of [tex]e^{-ct}[/tex] decreases

This implies that:

[tex]{t \to \infty} = {e^{-ct} \to 0}[/tex]

So:

The value of P(t) for large values is:

[tex]P(\infty) = \frac{1200}{1 + 11 * 0}[/tex]

[tex]P(\infty) = \frac{1200}{1 + 0}[/tex]

[tex]P(\infty) = \frac{1200}{1}[/tex]

[tex]P(\infty) = 1200[/tex]

Answer:

33.33%

Step-by-step explanation:

Given :

Breakup percentage = 15

New relationship percentage = 30

To obtain the steady state percentage of residents who are uninvolved, we could relate the scenario to the natural unemployment rate relation : seperation rate ÷ (seperation rate * finding rate)

Hence, we could use the Relation as this ;

Breakup percentage ÷ (Breakup percentage + new relationship rate)

15% ÷ (15% + 30%)

0.15 ÷ (0.15 + 0.30)

0.15 ÷ 0.45

= 0.33333

= 33.33%

Answer:

true

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

The equation for the dotted line is y=(-1/2)x, so therefore y<(-1/2)x must be the area under the dotted line.

The equation for the solid line is y=2x+3, so therefore y≥2x+3 must be the area above the solid line.

The section that is both under the dotted line and above the solid line is C.
