What is the measure of∠ABC?

Answers

Answer 1

Answer:

Step-by-step explanation:

the interior angles of a square add upto 360

and from the arrows we know that the parallel sides are equal

so there will be two angles which are 85

so:

360-85-85 = 190

190/2 = 95

Given Below. [ done below, side changing which changed sign + to - and - to + ]

Step-by-step explanation:

6. x + 21 = 56

→ x = 56 – 21

→ x = 35

7. n – 13 = 8

→ n = 8 + 13

→ n = 21

8. w – 7 =41

→ w = 41 + 7

→ w = 48

9. b + 22 = 89

→ b = 89 – 22

→ b = 67

10. z – 53 = 26

→ z = 26 + 53

→ z = 79

Answers

When looking at it, you can see that the location of the 9 and 12 are the same. So, you can solve by first finding the difference in the two. Turns out 12 is 4/3 times bigger than 9. So, divide each of your sides to figure out what each side is.
X = 17.25
Y = 18
Z = 17.25

Answers

Answer:

[tex]x=3c\sqrt{a} -b^2[/tex]

Step-by-step explanation:

[tex]\sqrt{a} =\dfrac{x+b^2}{3c}[/tex]

Multiply both sides by 3c:

[tex]\implies \sqrt{a} \cdot 3c=\dfrac{(x+b^2) \cdot 3c}{3c}[/tex]

[tex]\implies 3c\sqrt{a} =x+b^2[/tex]

Subtract [tex]b^2[/tex] from both sides:

[tex]\implies 3c\sqrt{a} -b^2=x+b^2-b^2[/tex]

[tex]\implies 3c\sqrt{a}-b^2=x[/tex]

Switch sides:

[tex]\implies x=3c\sqrt{a} -b^2[/tex]

A polling company is trying to estimate the percentage of adults that consider themselves happy. A confidence interval based on a sample size of 360 has a larger than desired margin of error. The company wants to conduct another poll and obtain another confidence interval of the same level but reduce the error to one-third the size of the original sample. How many adults should they now interview

Answers

Reducing the sample size to one-third, increases the error by √3.

Margin of Error

The margin of error is given by:

[tex]E=z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{n} } \\\\where\ z_\frac{\alpha}{2} \ is \ the \ confidence\ level\ z\ score, \sigma\ is \ mean\ and\ n\ is\ sample\ size.\\\\n=360, hence:\\\\E=z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{360} } \\\\E=0.0527(z_\frac{\alpha}{2} *\sigma)\\\\For\ n = 1/3 * 360=120:\\\\\\E=z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{120} } \\\\E=0.09122(z_\frac{\alpha}{2} *\sigma)[/tex]

Frederick asked a bank teller to cash a $390 check using $20 and $50 bills. If the teller gave
him 15 bills, how many of each did he receive?

Answers

12 of $20 and 3 of $50 totally didnt edit it... lolol..

Answer:

12 $20 Bills & 3 $50 Bills

Step-by-step explanation:

Because if the total is $390, Then if you get 10 $20 Bill that would equal $200 Bills and if you get 2 $50 Bills then you would get $100. Add the $200 Bills & the $100 Bills you get $300 Bills.

Then you get 1 $50 Bill and 2 $20 Dollar Bills you get $90 Bills.

Add $300 Bills with $90 Bills and you get $390.

If you add the number of bills handed it would be 15.

HELP ME PLEASE!!! A ball is thrown in the air from a platform that is 112 feet above ground level with an initial vertical velocity of 32 feet per second. The height of the ball, in feet, can be represented by the function shown where t is the time, in seconds, since the ball was thrown.

h(t)=−16t2+32t+112

Which of the following equations shows the function rewritten in the form that would be best used to identify the maximum height of the ball?

Question 16 options:

h(t)=−16(t−2)2+112

h(t)=−16(t−1)2+80

h(t)=−16(t−1)2+96

h(t)=−16(t−1)2+128

Answers

The ball thrown upwards follows a parabolic path

The equation that shows the function rewritten in the form that would be best used to identify the maximum height of the ball is [tex]h(t)=-16(t-1)^2+128[/tex]

How to determine the equivalent equation

The equation is given as:

[tex]h(t)=-16t^2+32t+112[/tex]

Factor out -16

[tex]h(t)=-16(t^2-2t)+112[/tex]

Express the bracket as a perfect square expression

[tex]h(t)=-16(t^2-2t + 1 - 1)+112[/tex]

Factor out -4

[tex]h(t)=-16(t^2-2t + 1)+112 + 16 * 1[/tex]

[tex]h(t)=-16(t^2-2t + 1)+128[/tex]

Express as a perfect square

[tex]h(t)=-16(t-1)^2+128[/tex]

Hence, the equivalent expression is [tex]h(t)=-16(t-1)^2+128[/tex]

The Answer is 175.86 cm^2

Step-by-step explanation:

6.75*10=67.5 cm^2

10*4.3*2=86 cm^2

86+22.36+67.5=175.86 cm^2

Hoped this helped ^^

= 234.02

10 x 6.75 = 67.5 x 3 202.5

4.3 x 5.2 = 21.84 square root = 4.67

6.7/2 = 2 = 3.375

15.76 x 2 = 31.52

202.5 + 31.52 = 234.02

Answers

We need to isolate x. We can do that by adding 9 to both sides which gives us x^2 = 9. Next, we can isolate x by taking the square root from both sides. This gives us x = 3. Additionally, x = -3 is also an answer because a negative squared becomes positive.

The answers are: x = 3, x = -3.
