Answer:

20√2 cm

Step-by-step explanation:

The required perimeter of the square is 20√2 cm.

Answer:

9°C

Step-by-step explanation:

quantity of heat energy absorbed is expressed as;

Q = mcΔt

m is the mass

c is the specific heat capacity

Δt is the change in temperature

Substitute the given values

3456 = 3 * 128 Δt

3456 = 384Δt

Δt = 3456/384

Δt = 9°C

Hence the temperature change is 9°C

Answer:

I believe the answer is 8.16 pardon me if it's wrong.

Answer:

8.18

Step-by-step explanation:

First, note that 8.175 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:

Integer Part: 8

Fractional Part: 175

To round 8.175 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part.

We use the following rules to round 8.175 to the nearest hundredth:

A) If the last digit in the fractional part of 8.175 is less than 5, then simply remove the last the digit of the fractional part.

B) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit.

C) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is less than 9, then add 1 to the first digit in fractional part and make the second digit in fractional part 0. Then remove the third digit.

D) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is 9, then add 1 to the integer part and make the fractional part 00.

With 8.175, rule B applies and 8.175 rounded to the nearest hundredth is:

8.18

Answer:

95 points

Step-by-step explanation:

Given

[tex]n = 370[/tex] --- expected point

See attachment for points

Required

An inequality to determine the points needed

First, we calculate the points (p) Lesha has already accumulated.

[tex]p = Test\ 1 + Test\ 2 + Test\ 3[/tex]

[tex]p = 75 + 100 + 100[/tex]

[tex]p = 275[/tex]

Let the number of points needed be t.

So:

[tex]p + t = 370[/tex] ---- i.e. She must score a total of 370

Make t the subject

[tex]t = 370 -p[/tex]

Substitute 275 for p

[tex]t = 370 -275[/tex]

[tex]t = 95[/tex]

Answer:94.5

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

For a proportional relationship :

y = kx

Where , k = constant of proportionality

Taking the first set of data:

x = 50 ; y = 10

10 = 50k

k = 10/ 50 = 1/5

Hence, the proportional equation or relation is :

y = 1/5x

Check if this is true for other data points on the data :

Taking the second data point :

x = 85 ; check if y will be 20

From :

y = 1/5x

y = 1/5*85

y = 85/5

y = 17

Since ;

y value from the equation isn't the same as that in the table, then the table does not show a proportional relationship.

Answer:

A and D

Step-by-step explanation:

Answer:

A. 2 + (−2) = 2 - 2= 0, true.

B. (−3) + (−4) = - 3 - 4 = -7 is negative, False

C. −2 − (− 2) = -2 + 2 = 0, neither positive nor negative, false.

D. 5 + (−2) = 5 - 2 = 3,is positive true.

E. 7 − (−10)= 7 + 10 = 17  is psoitive, false

Answer:

[tex]y = \frac{11}{8}x + 50[/tex]

Step-by-step explanation:

Given

See attachment for plot

Required

The line of best fit

From the attached plot, we have:

[tex](x_1,y_1) = (0,50)[/tex]

[tex](x_2,y_2) = (80,160)[/tex]

Calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{160 - 50}{80-0}[/tex]

[tex]m = \frac{110}{80}[/tex]

[tex]m = \frac{11}{8}[/tex]

The line of best fit is then calculated as:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = \frac{11}{8}(x - 0) + 50[/tex]

[tex]y = \frac{11}{8}x + 50[/tex]

Ok, im guessing that this is all about mean

First mean is just adding everything up for example:

5+5+10+10+5

so the answer is 35, but that isnt completely finished you need to divide 35 by 5, or how many numbers were added then you get the mean for my example the mean is 7

Step-by-step explanation:

Let the number of cards Aaron has : A

Given :

⊕   Bonny has twice as many cards as Aaron

⊕   Connor has 6 cards more than Bonny

⊕   Total cards : 101

⇒  Number of cards Bonny has : 2A

⇒  Number of cards Connor has : 2A + 6

⇒   Aaron cards + Bonny cards + Connor cards = 101

⇒   A + 2A + 2A + 6 = 101

⇒   5A = 101 - 6

⇒   5A = 95

⇒   A = 19

Answer : Aaron has 19 Cards

Step-by-step explanation:

you know that QPS adds up to 47

so the sum of RPS and QPR shoukd = 47

(3x - 38) + (7x - 95) = 47

you then solve for x then you can use that to find QPR

Answer:

There are 6 boxes

Step-by-step explanation:

We know there are 45 frames and 3 broken ones, so there are 48 frames in total.

We know there are 8 boxes that have the frames.

let x equal the amount of picture frames in a box

8x=48

8x/8 = 48/8

x=6
