How do I get to this answer step by step pleaseee quickly!!!!

Answer:

h ≤ 45

Step-by-step explanation:

The maximum height is 45 feets

Let the height of the object = h

Hence, the sentence means that the height, h of the object cannot be beyond 45 feets ;

This means the height can be any number of feets less than or equal to 45 feets

Hence, h ≤ 45

Answer: -10 (or 2)

Step-by-step explanation:  Absolute value gets rid of the negative so you can solve it with a positive or negative number as long as the interger still has the same value. (|-2|=2 and |+2|=2) so |-10+4|=6

Answer:

Step-by-step explanation:

#27). 6k² = 48

k = √8 = 2√2

x = [tex]\frac{8}{2\sqrt{2} }[/tex] = 2√2 cm

y = [tex]\frac{12}{2\sqrt{2} }[/tex] = 3√2 cm

#29). 16k² = 48

k = √3

x = [tex]\frac{8}{\sqrt{3} }[/tex] = [tex]\frac{8\sqrt{3} }{3}[/tex] cm

y = [tex]\frac{12}{\sqrt{3} }[/tex] = 4√3 cm

Hi there!

[tex]\large\boxed{\text{ P = 31ft, A = 35ft}^2}[/tex]

Perimeter: Add up all the side lengths.

14 + 10 + 7 = 31 ft.

Area: Use the following formula:

A = 1/2(bh) where:

b = bass

h = height

Thus:

A = 1/2(10 · 7) = 35 ft²

Answer:    What grade are you in

Answer:

the answer is 20 percent

Answer:

the answer is 20 percent

Answer/Step-by-step explanation:

Ok so x,y. is the first thing you need to know A. 1, -5 = X, -Y.

the number from the x grid goes before the y see the arrows seperating the squares the vertical line is the X any numbers coming off of x go before y ok, x, y.

See the -5, -5 on the bottom right square both of those are negative and since E. is negative (-2, -2) it gets placed in the negative bottom right square ok.

now you see how for some squares there is only 1 number for them well the number on the other side where there is no number is the number. In the top right square there is only 5 on the y line meaning that if u look beyond that and where the other number suppose to be the -5 is there so -5 is the answer for that ok.

(The 0 in the middle is called the "Origin")

Hope this helps! I didn't exactly answer because there's no way to answer without downloading or submitting an image but it wont let me download it for some reason.

Top right square = -5, 5.

C. goes into the top right square

Top left = 5, 5.

B. goes into the top left square

Bottom right square = -5, -5.

E. gets placed in the bottom right square

Bottom left square = 5, -5.

D. gets placed in the bottom left square

A. gets placed in the bottom left square

a) 5 pizzas need to be ordered and half of a pizza will be left over aka 0.5

b) $45

Step-by-step explanation:

Answer:

In the explanation I'm 80% sure it's this

Step-by-step explanation:

4 quarters in the pizza so

18 divided by 4= 4.5

4.5 rounded is 5 so she will need 5 pizzas because you can't buy 4 1/2 pizzas.

10*5= 50 so she will need to spend 50$ on the pizza.

The number of adult tickets sold will be 275.

Given is that a total of 494 tickets were sold for the school play. They were either adult tickets or student tickets. There were 56 fewer student tickets sold than adult tickets.

Assume that the number of adult tickets sold are [x] and the student tickets sold are [y]. Then -

x + y = 494

y = x - 56

So, we can write the equation as -

x + x - 56 = 494

2x = 550

x = 275

Then, we can find [y] as -

y = 275 - 56 = 219

y = 219

Therefore, the number of adult tickets sold will be 275.

Answer:

9 yrs ago

Step-by-step explanation:

(50-x)(20-x) = 451

x^2-70x + 1000 = 451

x^2-70x + 549 = 0

(x-9)(x-61) = 0

x = 9 (if it was 61 yrs ago, the father and son both wouldnt be a live)

Answer:

Height = 4 cm and slant height = 5 cm

Step-by-step explanation:

Given that,

The surface area of the cone, A = 75.4 cm²

Radius, r = 3 cm

The surface area of the cone is given by the formula as follows :

[tex]A=\pi r^2+\pi rl[/tex]

Put all the values,

[tex]75.4=3.14\times 3^2+3.14\times 3\times l\\\\75.4=28.26+9.42l\\\\75.4-28.26=9.42l\\\\47.14=9.42l\\\\l=\dfrac{47.14}{9.42}\\\\l=5\ cm[/tex]

Also,

[tex]l^2=r^2+h^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{5^2-3^2}\\\\h=4\ cm[/tex]

Hence, the height of the cone is 4 cm and the slant height is 5 cm.

Answer:

2(x-y+1)  Is The Awnser

Answer:

132

Step-by-step explanation:

X is smaller number

x + 71 is larger number.

x+ (x+71)=193

2x = 193-71

2x=122

x=61

x+71=largest number

61+71=132 largest numher

check answer

x+(x+71)=193

61+132=193

Answer:

The larger of the two numbers is 132.

Step-by-step explanation:

let x be the larger number and y be the smaller number.

x + y = 193 [Equatio#1]

x = y +71 [Equation#2]

substitute x from equation #2 into equation # 1:

(y+71) + y = 193

2y = 193 - 71

2y = 122

y = 61

substitute this value of y back into equation #2 to solve for x:

x = (61)+71

x= 132

the larger number is 132.

The area (A) of a trapezoid is calculated as follows:

A = 1/2 * sum of the parallel sides * height

In this case:

A = 1/2 * (3.4 + 1.1) * 2 = 4.5 cm^2.

Answer:

x+2

Step-by-step explanation:

The firs 3 observations are x, x+2, x+4

Mean = sum of data/samaple size

Mean = x+x+2+x+4/3

MEan = 3x+6/3

Mean = 3(x+2)/3

Mean = x+2

Hence the required mean is x+2

Answer:

0.0082 = 0.82% probability that the mean battery life would be greater than 523.8 minutes

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Standard deviation of 86 minutes with a mean life of 505 minutes.

This means that [tex]\sigma = 86, \mu = 505[/tex]

Sample of 120:

This means that [tex]n = 120, s = \frac{86}{\sqrt{120}}[/tex]

What is the probability that the mean battery life would be greater than 523.8 minutes?

This is 1 subtracted by the p-value of Z when X = 523.8. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{523.8 - 505}{\frac{86}{\sqrt{120}}}[/tex]

[tex]Z = 2.39[/tex]

[tex]Z = 2.39[/tex] has a p-value of 0.9918.

1 - 0.9918 = 0.0082

0.0082 = 0.82% probability that the mean battery life would be greater than 523.8 minutes

Answer:

m<G = 59°

Step-by-step explanation:

Recall: the angle formed outside a circle when 2 secants intercept is equal to half of the difference of the intercepted arcs

m<G = ½(arc TE - arc HF)

m<G = ½(175 - 57)

m<G = ½(118)

m<G = 59°
