Answer:

The missing side length is 24.98 units

Step-by-step explanation:

Given

The attached right-triangle

Required

The length of the missing length

Let the missing length be x.

Apply Pythagoras theorem

[tex]Hyp^2 = Opp^2 + Adj^2[/tex]

This gives

[tex]43^2 = 35^2 + x^2[/tex]

[tex]1849 = 1225 + x^2[/tex]

Collect like terms

[tex]x^2 = 1849 - 1225[/tex]

[tex]x^2 = 624[/tex]

Take square roots of both sides

[tex]x = \sqrt{624[/tex]

[tex]x = 24.98[/tex] --- approximated

Answer:

6m + 2n

Step-by-step explanation:

we have to added up the like therms

like therms are therms that have the same literal part

6m + 2n

Answer:

7m-m+4n-2n

m(7-1)+2n(2-1)

m(6)+2n(1)

6m+2n

Answer:

the number of copies have been sold to date is 3,036 copies

Step-by-step explanation:

Given that

There is 31,300 book copies sold in the first month

And, this represent 9.7% of the number of copies sold to date

we need to find out the no of copies have been sold to date

So,

= 31,300 copies × 9.7%

= 3,036 copies

Hence, the number of copies have been sold to date is 3,036 copies

Therefore the same would be considered and relevant too

Answer:

[tex]\sqrt{54}[/tex] and [tex]\sqrt{120}[/tex]

Step-by-step explanation:

If a number 'x' is a perfect square, then [tex]\sqrt{x}[/tex] is rational.

25, 36 and 81 are perfect squares, but 54 and 120 aren't, so the irrational values are [tex]\sqrt{54}[/tex] and [tex]\sqrt{120}[/tex]

Answer:

Square root of 54 and square root of 120

Step-by-step explanation:

you are an angel and i love you so much. i would just comment but it wont let me. you're the best!!!

Answer:

Lower confidence boundary = 134.525

μ ≥ 134.525

Step-by-step explanation:

From the data:

Sample size, n = 153

Sample mean, xbar = 135.39

Standard deviation, s = 4.59

Zcritical at 99% = 2.33 (one sided)

Confidence interval :

Xbar ± standard Error

Standard Error = Zcritical * s/√n

Standard Error = 2.33 * 4.59/√153 = 0.865

Lower boundary:

Xbar - standard error

135.39 - 0.865 = 134.525

μ ≥ 134.525

We Can be 99% confidence that the true average ultimate tensile strength is atleast 134.525

Answer:

Ermm there no question bud, whats the question?

Answer:

slope=-9/2

y int- 6

Step-by-step explanation:

okay lets take two points

-2,15 and -6,33

the slope is 33-15/ -6-(-2)= 18/-4=-9/2

equation is y=mx+b where m is slope and b is y intercept

so plugging values in we get

15=-2(-9/2)+b

15=9+b

b=6

Answer:

6

Step-by-step explanation:

The circles diameter is 6 because circumference is found when you do pi x diameter and since 18.84 ÷ 3.14 = 6 that means our diameter is 6

Hope this helps!

Step-by-step explanation:

give brainliest pls and thank you

Answer: 27

Step-by-step explanation:

Given

During 3 days the cat was catching mice

Suppose the first-day joy caught x mice

So, on the second day, it is x+3

on the third day, joy catches twice as many mice as on the first day i.e. 2x

or we can also write, no of mice caught on the second day plus 3 is equal to no of mouse caught on the third day

[tex]\Rightarrow x+3+3=2x\\\Rightarrow x=6[/tex]

In three day time, it is

[tex]\Rightarrow x+x+3+2x\\\Rightarrow 4x+3\\\Rightarrow 4\times 6+3=27[/tex]

Answer:

letter corresponds to the base=b

letter corresponds to the slant height=s

letter corresponds to the height=,h

Answer:

x= 20

Step-by-step explanation:

2x + 60 = 100

> subtract 60 both sides

2x = 40

> divide both sides by 2

x= 20

Answer:

20

Step-by-step explanation:

2x+60=100

-60

2x=40/2

x=20

Answer:

2

Step-by-step explanation:

2(3x²-5)-5=9

6x²-10-5=9

6x²-15=9

6x²=9+15

6x²=24

x²=24/6

x²=4

x=2

Answer:

-18

Step-by-step explanation:

y=6x-3

6x-3=-18

-18=6x-3

Answer:

intercept: -3

slope: 6

Step-by-step explanation:

The number in the back and the operations are the y-intercept and the number multiplied by x is the slope.

Answer:

A

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

You can see angle B is much smaller than angle A because Angle B is an acute angle (smaller than 90°) while angle A isn't.

Answer:39

Step-by-step explanation: 13 x 3= 39

Answer:

13 = (1/3)m

Step-by-step explanation:

The word "is" is used when saying "equals"

"One third of a number m" is telling you to multiply (1/3) times "m".
