Answer:

See below

Step-by-step explanation:

[tex] \sqrt[3]{49} = 3.65930571002 \approx3.66 \\ \\ so \: \sqrt[3]{49} should \: lie \: at \: 3.6 \: which \: \\ fall \: between \: 3 \: and \: 4.[/tex]

Actually Lin did a mistake, she obtained square root and not cube root.

is it that you don't have a calculator or that you didn't know to multiply the two numbers?   ( most computers have built in calculators )  :/

Answer:48

Step-by-step explanation: 36 divided by 3/4 is the same thing as 36 multiplied by 4/3. Multiply and you should get 48 shirts. Hope this helps!

Answer:

Part A: The maximum of the graph is the highest point which is at (2.5, 2531.25). Since xx is the decrease in price and yy is the profit, the maximum of (2.5, 2531.25) means that the maximum profit is $2531.25 and occurs when the price of the t-shirts is decreased by $2.50.

Part B: The yy-intercept is when the graph intersects the yy-axis which occurs at about (0, 2500). The yy-intercept then means that the profit is $2500 if the price of the t-shirts does not decrease.

Part C: The solution of a graph is its xx-intercept(s). The graph crosses the xx-axis at (25,0) so this point is the solution. The solution means that the profit will be $0 if the price is decreased by $25.

Given:

In triangle XYZ, x = 27 cm, y = 79 cm and [tex]\angle C=142^\circ[/tex].

To find:

The length of z.

Solution:

In triangle XYZ, using the Law of cosine, we get

[tex]z^2=x^2+y^2-2xy\cos Z[/tex]

Putting the given values in the above formula, we get

[tex]z^2=(27)^2+(79)^2-2(27)(79)\cos (142^\circ)[/tex]

[tex]z^2=729+6241-4266(-0.788)[/tex]

[tex]z^2=6970+3361.608[/tex]

[tex]z^2=10331.608[/tex]

Taking square root on both sides.

[tex]z=\pm \sqrt{10331.608}[/tex]

[tex]z=\pm 101.6445178[/tex]

Approx the above value to the nearest number and side length cannot be negative. So,

[tex]z\approx \pm 102\text{ cm}[/tex]

Therefore, the length of z is about 102 cm.

Answer:102

Step-by-step explanation:

Answer:

X=-0.4

Y= - 2

Step-by-step explanation:

First we slove for x intetcept so we put 0 for y.

Y=5X-2

0=5X-2 Now move the variables to

the left side.

5x=-2 Divide both sides by 5

because the coefficient

of your variable is 5.

X=-0.4

Now let's solve for Y intetcept.

Y=5X-2

Y=5(0)-2

Y=-2

Answer:$1.50

Step-by-step explanation:

Answer:

[tex]h\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]

Step-by-step explanation:

Given the expression

[tex]S=\pi \:r\left(h+k\right)\:[/tex]

[tex]S=\pi \:r\left(h+k\right)\:[/tex]

Flip the equation

[tex]\pi r\left(h+k\right)\:=\:S[/tex]

Apply distributive law:  [tex]a\left(b+c\right)=ab+ac[/tex]

[tex]\pi hr+\pi kr=S[/tex]      

Add -πkr to both sides

[tex]\pi hr+\pi kr+\left(-\pi kr\right)=S+\left(-\pi kr\right)[/tex]

[tex]\pi hr\:=\:-\pi kr\:+\:S[/tex]

Divide both sides by πr

[tex]\pi hr\:/\:\pi r\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]

[tex]h\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]

Therefore, we conclude that:

[tex]h\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]

Answer:

Since you didn't specify congruency to which angle, I am giving below all angles that are congruent in two groups.

Step-by-step explanation:  

Group ONE:

All these angles are congruent <ABE = <BCF = <GBC = < HCD

Group TWO:

All these angles are congruent  <EBC = <CFD = <ABG = <BCH

Answer:

Step-by-step explanation:

We need to isolate "x" on one side of the inequality symbol, then we divide both sides by "-3", recalling that dividing by a negative number changes the direction of the inequality:

- 3 x < - 15

x > (-15) / (-3)

x > 5

Which can be represented on the number line as shown in the attached image.

0.375 is the correct answer

Answer:

0.365

Step-by-step explanation:

Answer:

45 degrees

Step-by-step explanation:

AOB = 140°

and an the angle bisector(OC) is a line which will divide AOB into 2 equal angles

which is 140÷2= 70

and if AOD = 25 then COD= 70-25

= 45 degrees

Answer:

Should be C

Step-by-step explanation:

C is similar by SSS because all the sides are in proportion

Answer: A

Step-by-step explanation: In order to answer this you need to understand the rules of exponents. Whenever you multiply two terms with the same base or variable you add the powers together. For example, 4x*2x = 8x^2 or x^4*x^2 = x^6. Any term with a negative exponent is equivalent to its reciprocal. For example x^-2 = 1/x^2.

Knowing this we expand this equation by multiplying. (2x^-2y) * (8x^-3y^-3) = 16x^-5y^-2. We now move the variables with negative exponents to the bottom. Giving us 16/(x^5y^2).

Answer:

0.0384

Step-by-step explanation:

Given that:

Mean (m) = 6.0

Standard deviation (s) = 2.0

Sample size (n) = 50

Probability that average amount is greater than 6.5

P(x > 6.5)

Obtain the Zscore using the relation :

Zscore = (x - m) / (s / sqrt(n))

Zscore = (6.5 - 6.0) / (2 / sqrt(50))

Zscore = 0.5 / 0.2828427

Zscore = 1.7677

Zscore = 1.77

P(Z > 1.77) = 1 - P(Z < 1.77)

P(Z > 1.77) = 1 - 0.9616

P(Z > 1.77) = 0.0384

Answer:

4.2%

Step-by-step explanation:

n=50, X=6.0, δ=2.0

Z=[tex]\frac{6.5-6.0}{2.0}[/tex]  =  0.25

F(Z)= 4.2% based on the chart in the FE Handbook
