Please solve......... thanks

Answer:

The unknown angle =

27°

Note :

SOH = Sin angle = Opposite/hypotenuse

CAH = Cos angle = Adjacent/Hypotenuse

TOA = Tan angle = Opposite/Adjacent

Answer:

[tex]\theta \approx 27.5\º[/tex]

Step-by-step explanation:

Once

[tex]$\sin(\theta) = \dfrac{\text{Opposite}}{\text{hypotenuse}} =\frac{12}{26}=\frac{6}{13} $[/tex]

And

[tex]\arcsin \left(\dfrac{6}{13} \right)=\theta[/tex]

[tex]\theta \approx 27.5\º[/tex]

Answer:

49 eggs.

Step-by-step explanation:

The formula for Margin of Error =

z × standard deviation/√number of samples

z = z score of 98% confidence interval = 2.326

Margin of Error = Half a day = 1/2day = 0.5 day

Standard deviation = 1.5 days

Number of samples = number of eggs he needs to sample = unknown.

Imputing these above values into the formula

Margin of Error = z × standard deviation/√number of samples

0.5 = 2.326 × 1.5/√n

Cross Multiply

0.5 × √n = 2.326 × 1.5

√n = 2.326 × 1.5/0.5

√n = 3.489/0.5

√n = 6.978

Square both sides

(√n)² = 6.978²

n = 48.692484

n ≈ Approximately to the nearest whole number = 49

Therefore, the number of eggs he needs to sample to create the desired interval is approximately to the nearest whole number 49 eggs

Step-by-step explanation:

You have to put the numbers in order then find the middle number.

Numbers in order: 2,3,6,6,7,8,8,8,15

Then cross out the numbers on the end (one by one) until you get to the middle number. (If there are two numbers left once you're done then you add them then divide by 2)

Answer: 2y by 4x

Step-by-step explanation:

Each group can clean 200 ÷ 5 = 40 yards each minute, so together the two groups can clean 80 yards each minute. So, it takes 3520 ÷ 80 = 44 minutes to clean 2 miles.

Answer:

Step-by-step explanation:

2x + 4 = 6x - 10

Minus 2x on both sides

4 = 4x - 10

Add 10 on both sides

14 = 4x

Divide by 4 on both sides

14/4 = x

x = 14/4

Simplify fraction

x = 7/2 or x = 3 1/2

Answer:

8x < 12y

Step-by-step explanation:

If you divide 25 by 3, you get 8.3333... (the threes go on forever), which you can round to 8, because little Timmy isn't going to buy .3 of a cookie. If you divide 25 by 2, you get 12.5, which you round down to 12. I know you normally don't round 5 down, but we are talking about food here.

Therefore, Tim can buy less cookies than candies. He can buy 8 cookies, and 12 candies.

Either way, Timmy's gonna be fat.

Answer:

x=11

Step-by-step explanation: ( not good at explaining) Hope this helps

Divide both sides of the equation by 2

4+3x=37

Subtract 4

3x=37-4

Subtract 37-4

3x=33

and divide by 3

x=11

3350

5(4×) is 20 so 20+10=30+15=45+30=75+825=900+775=1675+800=2475+875=3350

Answer:

Step-by-step explanation:

Let y(t) = vt..... 1

Differentiating y(t) with respect to t twice will give;

y'(t) = v(1) + v't

y'(t) = v+v't .... 2

For y''(t);

y''(t) = v'+v'(1)+v''t

y''(t) = 2v'+v''t.... 3

Substitute equation 1, 2 and 3 into the differential equation

t²y′′−t(t+3)y′+(t+3)y=0

t²(2v'+v''t) −t(t+3)(v+v't)+(t+3)(vt)=0

t²(2v'+v''t) −(t²+3t)(v+v't)+(t+3)(vt)=0

Open the parentheses

2t²v'+t³v''-(t²v+t³v'+3tv+3t²v')+t²v+3vt= 0

2t²v'+t³v''-t²v-t³v'-3tv-3t²v'+t²v+3vt=0

Collect like terms according to the degree

t³v''+2t²v'-3t²v'-t³v'-t²v+t²v-3vt+3vt=0

t³v''-t²v'-t³v' =0

t²(tv"-v'-tv') = 0

tv"-v'-tv' = 0

tv"-v'(1+t) = 0

Reduce the degree by substituting p as v' to have;

tp'-p(1+t) = 0

tp' = p(1+t)

Separate the variables

p'/p = (1+t)/t

p'/p = 1/t + 1

Integrate both sides of the equation

ln(p) = lnt + t +K

lnp-lnt = t+K

ln(p/t) = t+K

p/t = e^(t+K)

p = Cte^t

v' = Cte^t

Integrate both sides

v = C{te^t - integral (e^t)}

v(t) = C(te^t - e^t}

y(t)/t = C(te^t - e^t}

y(t) = C(t²e^t-te^t)

Since the solution of second order differential equation

y(t) = C1e^at+C2te^t

In comparison the second solution to the differential equation y(t) will be t²e^t

Answer:

I think its 2/3 x 9

Step-by-step explanation:

My apologies if that isn't correct!

The counterexample for the conditional statement "If two positive numbers are multiplied together, then the product will be greater than both of the two positive numbers" will be 2/3 x 9.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

We can utilize multiplication for a number of common tasks, such as figuring out how much it will cost to buy several identical things, calculating sales tax, and figuring out area and other geometric measurements.

It is given if the two positive numbers are multiplied together, then the product will be greater than both of the two positive numbers.

If the two positive numbers are x and y from the given condition,

xy > x

xy> y

The two numbers are obtained as  2/3 and 9.

=2/3 x 9

=6

Thus, the counterexample for the conditional statement "If two positive numbers are multiplied together, then the product will be greater than both of the two positive numbers" will be 2/3 x 9.

Answer:

x=9.6

Step-by-step explanation:

We are given the proportion:

[tex]\frac{2}{5}=\frac{x}{24}[/tex]

We are asked to solve for x. Therefore, we must isolate x on one side of the proportion.

x is being divided by 24. The inverse of division is multiplication. Multiply both sides of the proportion by 24.

[tex]24*\frac{2}{5}=\frac{x}{24}*24[/tex]

[tex]24*\frac{2}{5}=z[/tex]

[tex]24*0.4=x[/tex]

[tex]9.6=x[/tex]

[tex]x=9.6[/tex]

x is equal to 9.6 The complete proportion is [tex]\frac{2}{5}=\frac{9.6}{24}[/tex]
