( multiple choice)What is the percent error in this scenario to the nearest tenth of a percent? The actual temperature was 65 °, but Tom read 69° on his thermometer.
A: 6.2%
B: 12%
C: 93.8%
D: 300%​

Answer:

a)72% b)75%

Step-by-step explanation:

I’m not really sure bout a. If it changed to 50, I kept the amount she answered correct but out of 50-(36/50) to get the percent. b) is the 36 she got correct out of the 48 she tried to do-36/48 x 100

Answer:

15/22

Step-by-step explanation:

x° + 2y° = 180°   ⇒   2y° = 180° - x°

x° = 60°   {three sides of the same lengh, means three angles=60°}

2y° = 180° - 60°

2y° = 120°

y° = 60°

Given:

[tex]\overline{BD} \cong \overline{BE}[/tex]

DE bisects [tex]\overline{AB}[/tex].

DE bisects [tex]\overline{BC}[/tex].

To prove:

[tex]\overline{AB} \cong \overline{BC}[/tex]

Proof:

DE bisects [tex]\overline{AB}[/tex]

Then, [tex]AD=BD[/tex].         ...(i)

DE bisects [tex]\overline{BC}[/tex].

Then, [tex]BE=CE[/tex].           ...(ii)

We have,

[tex]\overline{BD} \cong \overline{BE}[/tex]        ...(iii)

Using (i), (ii) and (iii), we get

[tex]\overline{AD} \cong \overline{CE}[/tex]         ...(iv)

Adding (iii) and (iv), we get

[tex]\overline{BD}+\overline{AD} \cong \overline{BE}+\overline{CE}[/tex]

[tex]\overline{AB} \cong \overline{BC}[/tex]

Hence proved.

Answer:

z = -44

Step-by-step explanation:

3/4 (x - 8) = 4

3(x - 8) = 16

3x - 24 = 16

3x = 40

x = 40/3

4 - 2x = -5x - z

4 = -3x - z

z = -3x - 4

z = -3(40/3) - 4

z = -40 - 4

z = -44

Answer:

Z=-44

Step-by-step explanation:

To figure out z. we have to figure out x first

So

3/4(x-8)=4

x-8=4÷3/4

x-8=4×4/3

x-8=16/3

3x-24=16

3x=16+24

3x=40

x=40/3

Now

4-2(40/3)=-5(40/3)-z

4-80/3=-200/3-z

z-68/3=-200/3

z=-200/3+68/3

z=-44

Answer:

B. $27,000

Step-by-step explanation:

Given that:

The base price of a car = $24300

The air conditioning costs = $725

The leather interior costs = $1225

Installation of four heated seats cost = $945

if we round each entity of item purchased to the nearest thousand, Then:

The base price of a car ≅ $24000

The air conditioning costs ≅ $1000

The leather interior costs ≅ $1000

Installation of four heated seats cost ≅ $1000

So, the total estimate = 24000 + 1000 + 1000 + 1000 = $27000

= $27000  to the nearest thousands

Answer:

They will spend less at the sunny side hotel

Step-by-step explanation:

The attachment completes the question.

From the question, we understand that there are 4 individuals involved.

And they will spend one night

First, we need to calculate the expenses in Traveler's hotel.

[tex]Rate = \$107.10[/tex] (for 3 people)

[tex]Additional\ Person = \$21.55[/tex] (for 1 person)

[tex]Breakfast = \$8.75 * 4[/tex] (for 4 people)

[tex]Tax = \$16.85[/tex]

Total Expenses

[tex]Total = \$107.10 + \$21.55 + \$8.75* 4 + \$16.85[/tex]

[tex]Total = \$107.10 + \$21.55 + \$35.00 + \$16.85[/tex]

[tex]Total = \$108.50[/tex]

For Sunny Side hotel:

[tex]Rate = \$152.95[/tex] (for 4 people)

[tex]Tax = \$21.34[/tex]

Total Expenses:

[tex]Total = \$152.95 + \$21.34[/tex]

[tex]Total = \$174.29[/tex]

By comparison, they will spend less at the sunny side hotel.

Answer:

The answer is A) -1 + 12i

Step-by-step explanation:

(7 + 3i) + (-8 + 9i)

(7 - 8) + (3 + 9)i

7 - 8 = - 1

3 + 9 = 12

- 1 + 12

Step-by-step explanation:

If Jamal ate 2 slices, that means there are 6 slices left, and now make a ratio with the slices he ate with the ones remaining. Hope this helps

Answer:

6/2 or 3/1

Step-by-step explanation:

If Jamal ate 2 slices, then there must be 6 remaining.

That is the numerator in our ratio.

We know that Jamal has eaten 2 slices, so our denominator is 2.

We get:

6/2 or 3/1

Hope this helps! :)

Answer:

Please find attached the bar model that shows the comparison between Abba's previous height to the height by which Abba grew over the past year

Step-by-step explanation:

A bar model, in mathematics, is defined as a graphic depiction of a given quantity represented by numbers presented in a rectangular box or bar form that is then applied in finding numerical relationship solutions

The height by which Abba grew over the past 1 year = 1 ft.

Abba's current height = 5 feet

Therefore, Abba's initial height = 5 feet - 1 foot = 4 feet

Please find attached the bar model that compares Abba's previous height to the height Abba grew over the past year created with Microsoft Visio

Answer:

srry this aint no 5 point question Ma'am (absolutely no hardfeelings :D)

Step-by-step explanation:

Answer:

essentially, in these problems, youre finding the square root of each number. the square root should be a decimal thats in between two other numbers, and those will be the integers that the value of the square root is between. unless the value is exactly a number and a half, it will be closer to one integer than the other. the work is below.

square root of:

59= 7.68

68= 8.246

78= 8.83

93= 9.64

104= 10.198

124= 11.14

33= 5.74

185= 13.6

215= 14.66

these are just the square roots. but, as you can see, each number is between two other whole numbers on a number line. So, just write down what those numbers are.

7.68 is between 7 and 8

8.246 is between 8 and 9

8.83 is between 8 and 9

9.64 is between 9 and 10

10.198 is between 10 and 11

11.14 is between 11 and 12

5.74 is between 5 and 6

13.6 is between 13 and 14

14.66 is between 14 and 15

so, we know thw numbers that each decimal is between, but we have to find which one each is cloest to. in order to do that, just know that if the decimal is more than .5 its closer to the larger number, and its its less than .5, its closer to thw smaller number.

7.68 is closer to 8

8.246 is closer to 8

8.83 is closer to 9

9.64 is closer to 10

10.198 is closer to 10

11.14 is closer to 11

5.74 is closer to 6

13.6 is closer to 14

14.66 is closer to 15

Answer:

Not a function

Step-by-step explanation:

If you use the line/ pencil test ***I think that's what it's called...

you put a pencil flat on the graph and if it touches more than one point, it is not a function. This only works with some graphs.But it works with this one.  

Answer:

We know

sin (A + B) = sin A cos B + cos A sin B

sin (A - B) = sin A cos B - cos A sin B

(A + B) + sin (A - B)

= sin A cos B + cos A sin B + sin A cos B - cos A sin B

= sin A cos B + sin A cos B

= 2 sin A cos B

Answer:

[tex]A_4[/tex]

Step-by-step explanation:

The cost of the e-readers and the subscription of their services are

[tex]A_1(t)=5t+350[/tex]

[tex]A_2(t)=10t+250[/tex]

[tex]A_3(t)=499[/tex]

[tex]A_4(t)=15t+179[/tex]

The functions are of the form

[tex]A(t)=mt+c[/tex]

Where [tex]m[/tex] is the monthly subscription cost and [tex]c[/tex] is the cost of the e-reader.

So, 15 dollars is the highest subscription cost which is of the 4th e-reader.

Hence [tex]A_4[/tex] has the highest subscription cost.
