Answer:

13 in.

Step-by-step explanation:

First figure out the length of the diagonal of the base.

3²+4²=c²

9+16=c²

25=c²

√25=c

c=5

Now we can figure out the stick using the same method.

5²=12²=c²

25+144=c²

169=c²

√169=c

c=13

[tex]x-5\leq 12[/tex]

You add 5 to each side

[tex]x\leq 17[/tex]

This inequality will be correct if x is less than or equal to 17. Meaning any number less than 17 and including 17 will make the equation correct. For this reason you pick the one with a filled circle. The answer is H

Answer:

Step-by-step explanation:

3(4)+2(8)=7(4)+4(8)

12+16=28+32

28=60

Therefore, the expression is not true because they are not equal to each other

Please mark answer as brainliest

Answer:

3(4) + 2(8) = 7(4)+ 4(8)

12+16= 28+32

28 =60

No, the expression is not true

Answer:

x = 8

Step-by-step explanation:

Recall: Ratio of the corresponding side lengths of two similar figures are equal.

Therefore,

EF/AB = GH/CD

6/4 = 12/x

Cross multiply

6*x = 12*4

6x = 48

Divide both sides by 6

6x/6 = 48/6

x = 8

Answer: [tex]\dfrac{76}{89}[/tex]

Step-by-step explanation:

The pool of rats from which the researcher is drawing participants is composed of the following:

23 male albino rats

21 male spotted rats

35 female albino rats

11 female spotted rats

Total rats = 23+21+35+11 =90

[tex]P(male\ albino)=\dfrac{23}{90}[/tex]

After drawing first rat , total rats remained = 89

[tex]P(\text{either a female albino rat or a male spotted rat})=\dfrac{35+21}{89}=\dfrac{76}{89}[/tex]

The probability of choosing a male albino rat and then either a female albino rat or a male spotted rat = [tex]\dfrac{76}{89}[/tex]

Answer:

3 seconds

Step-by-step explanation:

Initial height = 144 feet

t = Time taken

The equation of the height from the ground is

[tex]h(t)=-16t^2+\text{Initial height}[/tex]

The time taken to reach the ground is needed. Here the ground is taken as reference so [tex]h(t)=0[/tex]

[tex]0=-16t^2+144\\\Rightarrow -144=-16t^2\\\Rightarrow t=\sqrt{\dfrac{144}{16}}\\\Rightarrow t=3\ \text{s}[/tex]

So, time taken by the quarter to reach the ground is 3 seconds.

Answer:

Step-by-step explanation:

It is a matter of just substituting the values into the given equation.

4m^2-2n+5

If m=5 and n=9 then it becomes

4(5^2)-2(9)+5

4(25)-18+5

100-18+5

87

Answer:

382

Step-by-step explanation:

Surface area = 2(7 × 8) + 2(7 × 9) + 2(8 × 9)

                      = 382

Answer:

SA=382

Steps:

SA=2(7×8)+2(7×9)+2(8×9)

SA=2×56+2×63+2×72

SA=112+126+144

SA=382

-16p was my answer after simplifying it

Answer:

120p - 16p = 104p

Step-by-step explanation:

-3p x -3p = 9p + 6p = 15p x 8p = 120p

8p x -2 = -16p

120p - 16p = 104p

Step-by-step explanation:

Answer: C :2400

Step-by-step explanation:

Part over whole and percent over 100 you put 15 as your percent and 100 over it then you put 360 as your part then you multiply 360x100=36,000 you divide that with 15 and you get 2,400

40.63%

Answer:

  5.  (d) 8

  6.  (c) 120°

Step-by-step explanation:

5. OC is a radius, just like BO is. The angle at B is a right angle, so the Pythagorean theorem can be used to find BO.

  AO² = BO² +BA²

  BO² = AO² -BA² = 17² -15² = 289 -225 = 64

  BO = CO = √64 = 8

__

6. The measure of arc IK is the same as the measure of the central angle. If we name the circle center X, then arc IK = ∠IXK = ∠HXL because those angles are vertical angles.

  arc IK = 120°

Answer:

sorry we cant see the work I would help if I see the pitcher plz

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Since the only difference in the aquariums is the length, you can find the difference by multiplying the difference in length with the rest of the dimensions.

Difference in length = 4ft - 3ft

                                 = 1ft

Difference in volume = 1ft × 2ft × 1ft

                                   = 2ft³

Answer:

10/7

Step-by-step explanation:

Use the slope formula y2-y1/x2-x1

You can’t reduce so the final answer is 10/7

Answer:B

Step-by-step explanation:the answers B because the closed circle is greater that or equal too, and because the inequality is greater than the arrow points to the left. B, the dot is on 7 which if we add that to 18 is 25 which is the greatest number that can work for this inequality making this answer correct.

Hope this helps you understand it!

Answer:

72

Step-by-step explanation:

Cut the square into two equal triangles along the diagonal

You know that half of the diagonal is 6 so multiply that by 2 to get 12 which is the hypotenuse of your triangles

Then use the pythagorean theorem to solve for the sides

a^2 + b^2 = 12^2

a^2 + b^2 = 144

Since the original shape was a square both sides a and b are equal

a^2 = b^2

a^2 + a^2 = 144

2a^2 = 144

a^2 = 144/2

a^2 = 72

a = [tex]\sqrt{72}[/tex]

Since a = b then a = [tex]\sqrt{72}[/tex] =b

Multiply both sides a and b to get the area of the square

[tex]\sqrt{72}[/tex] * [tex]\sqrt{72}[/tex] = 72
