Answer:  34 cookies baked last week

Step-by-step explanation:

138=4x-2

136=4x

34=x

Answer:

34 cookies!

Step-by-step explanation:

If we say the number of cookies that Desirae baked last week was 'x', we can make the following equation for how many she baked this week: 4x+2=138. Here are the following steps to solve for x:

4x=138-2=136

x=34

Therefore she baked 34 cookies last week.

Answer: 19.2 ft

Step-by-step explanation:

The distance between you, Player A and Player B are in the form of a right angled triangle so using the Pythagorean Rule, we can find the distance between you and Player A.

c² = a² + b²

c = hypotenuse = Distance between you and player A

a = Length of triangle

b = Height of triangle

c² = 12² + 15²

c² = 144 + 225

c = √369

c = 19.2 ft

Thickens (Height) = 0.068 cm

Step-by-step explanation:

Given:

Diameter of disc = 14 cm

Radius of disc = 14 / 2 = 7 cm

Surface area = 3 cm²

Find:

Thickens (Height)

Computation:

Disc is a cylinder in shape

Surface area = 2πrh

3 = 2(22/7)(h)(7)

3 = 44(h)

Thickens (Height) = 0.068 cm

Please tell me if im wrong

Answer:

For this we can first multiply both sides by dx:

[tex]dy = 4x^{1/6}dx[/tex]

Next we can integrate both sides:

[tex]\int dy = \int 4x^{1/6}dx\\[/tex]

We can then solve both integrals to get:

[tex]y = 4(\frac{6}{7}x^{\frac{7}{6}}+C_1) = \frac{24}{7}x^{\frac{7}{6}}+C_2[/tex]

We can just say the constant is C2. So the answer is

[tex]y = \frac{24}{7}x^{\frac{7}{6}}+C_2[/tex]

We can also check this by differentiating both sides. We will ultimately get the equation we with. If I made any mistakes or misread something, please let me know.

Answer:

-7(-p+6)

Step-by-step explanation:

Answer:

-7(-p+6)

Step-by-step explanation:

Answer:

[tex]7p-42[/tex]

Why:

To use the distributive property, you multiply all things within the parantheses by the -7 (in this case). To Multiply -p and -7, remember that a negative times a negative equals a positive, so it simply results in 7p. When you multiply -7 and 6, multiply them together and you get -42. You get [tex]7p+-42[/tex], but that's not a fully simplified equation, so get rid of the addition symbol and make the 42 positive. This expression is now fully simplfied into [tex]7p-42[/tex].

P.S. Never ever add a negative in an expression. Lots of teachers like to dock your points for doing it.

Answer:

X Intercept: (-10,0), Y Intercept: (0,2)

Step-by-step explanation:

Well, firstly you need to rewrite the equation to make it easier. After rewriting it you have the equation y=x/5+2 by adding the x to the right side and dividing everything by 5. Now simply plug in your zeroes in their respective places. For the x intercept, your y value must equal 0 so we have the equation 0=x/5+2. After solving it, x must be -10 in order for our y value to be 0 getting us for the x intercept (-10,0). For the y intercept, your x value must equal zero so you simply subsitute zero in the equation for x which I will do here: y=0/5+2. If our x value is zero, consequently, our y value will be 2 getting us for the y intercept, (0,2).

Answer:

A) H0: σ₁²-σ₂²= 0   against the claim  Ha: σ₁²-σ₂²≠0

B) t= 0.3543860

C)  t≥ t∝/2 ( d.f)=2.024394

D)1) There is no evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.

Step-by-step explanation:

The claim is that there is evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels which is the

alternate hypothesis

The null hypothesis is the reverse of the alternate hypothesis

The null hypothesis is that there is not enough evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.

Part A) H0: σ₁²-σ₂²= 0   against the claim  Ha: σ₁²-σ₂²≠0

Part B) t= x1`-x2`/ sqrt ( s₁²/n₁ + s₂²/n₂)

  t=  2.214- 2.0115/ sqrt ( 2.951657/20+  3.57855/20)

 t= 0.2025/ sqrt(0.14758285 + 0.1789275)

t= 0.2025/0.5714108

t= 0.3543860

Part C) for 2 tailed test the critical value of t is obtained by

t≥ t∝/2 ( d.f)= ± 2.024394

We look at the table with values 0.025 as ∝/2= 0.05/2= 0.025

in the degrees of freedom 38

The d.f = n1+n2-2= 20+20-2= 40-2= 38

Part D) Since the calculated value of t= 0.3543860 does not fall in the critical region  t≥ t∝/2 ( d.f)= ± 2.024394 we conclude that H0 is true and accept the null hypothesis.

So option 1 is correct

1) There is no evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.

Answer:

395.2 cm²

Step-by-step explanation:

2x12.7x6.72=170.688

2x6.72x5.78=77.6832

2x5.78x12.7=146.812

170.688+77.6832+146.812=395.1832

Answer:  A=395.2

Step-by-step explanation:

A=2(wl+hl+hw)

A=2[(12.7x5.78)+(6.72x5.78)+(6.72x12.7)]

A=2(73.406+38.8416+85.344)

A=2(197.5916)

A=395.1832

Rounded to nearest tenth..

A=395.2

Answer:

[tex] F)\displaystyle \: 100\pi{ x}^{8} {y}^{2} {z}^{ 6} [/tex]

Step-by-step explanation:

we are given r and the formula

we want to find the surface area of the shpare with the given r

to do so

we need our algebra skills

substitute the value of r:

[tex] \displaystyle \: S = 4\pi( {5x}^{4} y {z}^{ 3} {)}^{2} [/tex]

recall law of exponent

[tex] \displaystyle \: ({x}^{m} {)}^{n} \iff \: {x}^{mn} [/tex]

to simplify:

[tex] \displaystyle \: S = 4\pi({ {5}^{2} x}^{4 \times 2} {y}^{1 \times 2} {z}^{ 3 \times 2} )[/tex]

simplify multiplication:

[tex] \displaystyle \: S = 4\pi({ 25x}^{8} {y}^{2} {z}^{ 6} )[/tex]

distribute:

[tex] \displaystyle \: S = 100\pi{ x}^{8} {y}^{2} {z}^{ 6} [/tex]

hence our answer is F

Answer:

$1,620

Step-by-step explanation:

2% per year:

2% of 1,500 = 30

30 x 4 = 120

1500 + 120 = 1620

answer

x=28

explanation

so what would happen is you pay a fee of 22$ and then 1$ per visit and we are looking to see how many visits it take to get to 50$

what we do it put

22+x=50

x is how many visits it would take to 50$

so what we do is subtract 22 from both sides

x=50-22

x=28
