OMGGG I NEED THIS QUESTIONNN TOOOOOOWANNA WORK ON IT

Answer:

225sqft with 1in -> 5ft  = 9sqin

147sqft with 1in -> 7ft = 3sqin

256sqft with 1in ->8ft = 4sqin

128sqft with 1in -> 4ft = 8sqin

Step-by-step explanation:

To change from feet to inches, you just divide by the scaling factor (5, 7, 8, or 4) in this problem.  But because it is square feet to square inches, you must divide by the square of the scaling factor:

5*5 = 25

7*7 = 49

8*8 = 64

4*4 = 16

So:

225/25=9

147/49 = 3

256/64 = 4

128/16 = 8

Answer:      g(x) = Negative two-fifths(10)x

Step-by-step explanation:

In order to reflect a function over the x-axis, you have to multiply the function by minus one.

Given the function:

f(x) = 2/5(10)^x

Its reflection over the x-axis is:

-f(x) = -2/5(10)^x = g(x)

    750  : 275

30 x 25 : 11 x 25

       30 : 11

Answer: 16%

Step-by-step explanation:

Notice that 154 minutes is one standard deviation greater than the mean. Based on the empirical rule 68% of the finishing times are within one standard deviation of the mean, so 100%-68%=32% of the finishing times are outside of one standard deviation from the mean one either direction. Since the normal distribution is symmetric , half of the 32% will be less than the mean and half will be greater, so 16% of the finishing times are greater than the one standard deviation more than the mean.

The probability that race participant had a finishing time of greater than 154 minutes is 16%

The empirical rule states that for a normal distribution, 68% are within one standard deviation from the mean, 95% are within two standard deviation from the mean and 99.7% are are within three standard deviation from the mean.

Given that mean (μ) = 143, standard deviation σ = 11

The probability that race participant had a finishing time of greater than 154 minutes is 16% [(100% - 68%)/2]

Answer:

155 + [tex]x^{3}[/tex] + 14

Step-by-step explanation:

The variable x would represent the number/value we don't know, and in this case, we don't know what number is raised to the third power. This being said, x would represent that number.

The question, although worded a bit confusingly, asks to add 155, the number (x) to the exponent of 3, and 14. Mathematically, this would be 155 + [tex]x^{3}[/tex] + 14.

Answer:

[tex]Area= 37193\ cm^2[/tex]

Step-by-step explanation:

Given

[tex]q = 590cm[/tex]

[tex]r = 310cm[/tex]

[tex]\angle P =24^o[/tex]

Required

The area of [tex]\triangle PQR[/tex]

This is calculated as:

[tex]Area= \frac{1}{2} * qr* \sin(P)[/tex]

So, we have:

[tex]Area= \frac{1}{2} * 590cm * 310cm* \sin(24^o)[/tex]

[tex]Area= \frac{1}{2} * 590cm * 310cm* 0.4067[/tex]

[tex]Area= 37192.715cm^2[/tex]

[tex]Area= 37193\ cm^2[/tex] ----- approximated

Answer:

x=8                     x=-2

Step-by-step explanation:

|x-3| -10=-5

Add 10 to each side

|x-3| -10+10=-5+10

|x-3| =5

Now separate into two equations , one positive and one negative

x-3 = 5           x-3 = -5

Add 3 to each side

x-3+3 = 5+3    x-3+3 = -5 +3

x=8                     x=-2

Answer:

x = ± 8

Step-by-step explanation:

|x - 3| - 10 = - 5

|x - 3| - 10 + 10 = - 5 + 10

|x - 3| = 5

x - 3 = 5      

x - 3 + 3 = 5 + 3

x + 3 = - 5

x + 3 - 3 = - 5 - 3

x = - 8

Answer:

Step-by-step explanation:

We first turn 3x+4y=12 into standard form:

4y=-3x+12

y=-3/4x+3

By knowing the 2nd line is parallel to the first, the slopes are the same:

y=-3/4x+b

Plugging in (5,4) into the equation:

4=-15/4+b

b=1/4

Final equation=y=-3/4+1/4.

4 and 0 has the same place value and face value.

Answer:

0 and 4 are the digit which have same place and face value.

Answer:

The correct answer is B.

Step-by-step explanation:

The opposite of Square root is squaring, which is ².

Answer:

[tex] \frac{ \sqrt{a} }{ \sqrt{b} } = x \\ [/tex]

squaring both the sides

[tex]{( \frac{ \sqrt{a} }{ \sqrt{b} }) }^{2} = x ^{2} \\ [/tex]

B. [tex] \frac{ {a} }{ {b} } = x {}^{2} \\ [/tex]

Answer:

Parentheses. Add 2 and 5.

Step-by-step explanation:

Use the P.E.M.D.A.S expression. (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.) As you can see, there are parentheses in your expression, so use PEMDAS to do order of operations problems like this.

The square of z varies inversely as the square root of e. If z=36 when w=16, then value of z is 24 when w=81.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

The square of z varies inversely as the square root of e.

If z=36 when w=16

The value of z when w is 81 we need to find

z²=k/√e

where k is a proportionality constant

36²=k/√16

36²=k/4

Apply cross multiplication

1296(4)=k

5184=k

Now let us find when k is 5184 and w is 81

z²=5184/9

z²=576

Take square root on both sides

z=24

Hence, the value of z is 24 when w is 81.

Answer:

your image has the answer

Step-by-step explanation:

you can go type triangle calculator and type in everything

If square C is 64 in^2, then its dimensions are 8 x 8.

If square D is 81 in^2, then its dimensions are 9 x 9.

Since D is bigger than C and I sits in that extra space, then the dimensions of I are 1 x 1.

Since H is smaller than C, specifically I smaller, than its dimensions are 7 x 7.

Then, H and C make up one side of B, so 7 + 8 = 15. The dimensions of B are 15 x 15.

Since E is bigger than D by I, then the dimensions of E are 10 x 10.

If we find the length of the right side (B + C + D), which is 15 + 8 + 9 = 32, then we know that F + E + D must also add up to 32. F + 10 + 9 = 32 || F = 13. The dimensions of F are 13 x 13.

Then, F is E + G, so 13 = 10 + G. G = 3. The dimensions of G are 3 x 3.

Lastly, since we know the side length of the whole square is 32, then A + F must equal 32. 32 = A + 13. A = 19. The dimensions of A are 19 x 19.

A = 19 x 19 = 361 in^2

B = 15 x 15 = 225 in^2

C = 8 x 8 = 64 in^2

D = 9 x 9 = 81 in^2

E = 10 x 10 = 100 in^2

F = 13 x 13 = 169 in^2

G = 3 x 3 = 9 in^2

H = 7 x 7 = 49 in^2

I = 1 x 1 = 1 in^2

Hope this helps!! :)
