Answer:

60cm

24.84 ft

Step-by-step explanation:

First one:

think that you are moving right small triangle to the left

which makes it 12 x 5 rectangle = 60cm

Second one:

Kind of same way

which makes it 10.8 x 2.3 = 24.84

pls thanks and brainest

Answer:

2/8 is the right answer your welcome

2/8 of a jar more full.

Tip: ALWAYS circle the numbers or key information to get the best results.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Some key information in this problem is 7/8, and 5/8.

Since they asked us how much more and what fraction represents it, we should subtract 5/8 from 7/8 to find how much more  full Rick's jar is than Lisa's.

7/8 - 5/8 = 2/8

So in summary, Rick's jar is 2/8 more full than Lisa's jar.

Answer:

[tex]s^2 = 0.9938[/tex] --- sample variance

[tex]s = 0.9969[/tex] --- sample standard deviation

Step-by-step explanation:

Given

[tex]\begin{array}{cc}{Heights} & {Frequency} & {116.1-120.0} & {38} & {120.1-124.0} & {24} &{124.1-128.0} & {28} & {128.1-132.0} & {43} & {132.1-136.0} & {29} \ \end{array}[/tex]

Required

Calculate the sample variance and sample standard deviation

First, we calculate the midpoint of each class:

[tex]\begin{array}{ccc}{Heights} & {Frequency} & {m} &{116.1-120.0} & {38} & {118.05}& {120.1-124.0} & {24}& {122.05} &{124.1-128.0} & {28} &{126.05}& {128.1-132.0} & {43} & {130.05} &{132.1-136.0} & {29} &{134.05}\ \end{array}[/tex]

The midpoints are calculated by taking the average of the class intervals.

For instance:

Class 116.1 to 120.0 has a midpoint of

[tex]m = \frac{1}{2}(116.1+120.0)[/tex]

[tex]m = \frac{1}{2}(236.1)[/tex]

[tex]m = 118.05[/tex]

The same approach is applied to other classes.

Next, is to calculate the mean:

[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]

In this case, it is:

[tex]\bar x = \frac{\sum fm}{\sum f}[/tex]

Where

[tex]m = midpoint[/tex]

So, we have:

[tex]\bar x = \frac{118.05*38+122.05*24+126.05*28+130.05*43+134.05*29}{38+24+28+43+29}[/tex]

[tex]\bar x = \frac{20424.10}{162}[/tex]

[tex]\bar x = 126.07[/tex]

The sample variance (s^2) is:

[tex]s^2 = \frac{\sum(m - \bar x)^2}{\sum f -1}[/tex]

This gives:

[tex]s^2 = \frac{(118.05-126.07)^2+(122.05-126.07)^2+(126.05-126.07)^2+(130.05-126.07)^2+(134.05-126.07)^2}{38+24+28+43+29-1}[/tex]

[tex]s^2 = \frac{160.002}{161}[/tex]

[tex]s^2 = 0.9938[/tex]

The sample standard deviation (s) is:

[tex]s = \sqrt{s^2[/tex]

[tex]s = \sqrt{0.9938[/tex]

[tex]s = 0.9969[/tex]

Answer:

[tex]r=-3[/tex]

Step-by-step explanation:

The line that passes through the two points (6, -23) and (11, r) has a slope of 4.

We want to determine the missing value of r.

We can use the slope formula:

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

Let (6, -23) be (x₁, y₁) and let (11, r) be (x₂, y₂). The final answer should be 4. Therefore:

[tex]\displaystyle \frac{r-(-23)}{11-6}=4[/tex]

Simplify and evaluate:

[tex]\displaystyle \frac{r+23}{5}=4[/tex]

Multiply both sides by 5:

[tex]r+23=20[/tex]

Therefore:

[tex]r=-3[/tex]

Answer:48 ft to the second power

Step-by-step explanation:

I just got it right on iready

The area of the outdoor carpet that needed for the hole should be considered as the  48 ft².

Since

we know that

Area of the rectangle = Length (breadth)

here,

L = 12 ft

b =  5 ft

So,

area = 12 × 5  

= 60 ft²

Now

The cut off triangle area

area = 1/2 × base × height

= 1/2 × 4 × 3

= 12/2

= 6 ft²

Now

The cut off rectangle area should be

area = Lb

= 3 × 2

= 6 ft²

Now finally

The area of the outdoor carpet should be

= 60 - 6 - 6

= 48 ft²

Answer:

(a) Base 7

(b) Base 5

Step-by-step explanation:

(a) 42/3 = 13 testing base 7 we have:

4x7¹ + 2x7° = 28 + 2 = 30

3x7° = 3

1x7¹ + 3x7° = 7 + 3 = 10

30/3 = 10. Therefore, 42/3 = 13 is in base 7.

(b) 23 + 44 + 14 + 32 = 223. Testing base 5 we have:

2x5¹ + 3x5° = 10 + 3 = 13

4x5¹ + 4x5° = 20 + 4 = 24

1x5¹ + 4x5° = 5 + 4 = 9

3x5¹ + 2x5° = 15 + 2 = 17

2x5² + 2x5¹ + 3x5° = 50 + 10 + 3 = 63

13+24+9+17 = 63.

Therefore, it was done in base 5.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

I don’t know what was going on with those middle angles but adjacent angles must sum to 180 which 100 and 30 does not satisfy. The two upper angles must be (360-2(84))/2=96. It follows that the lower adjacent angles must be 180-96=84, just like the angles at top. Anyway the angle j must satisfy

j+2(84)=180

j+168=180

j=12 degrees
