Step-by-step explanation:

A) Find the total minutes that Anna walked.To find the average number of minutes, divide the total minutes by total number of days

B) Average number of minutes =

[tex]\frac{15*9 + 30*5 + 40*7 + 45*3 + 50*6}{30}\\\\= \frac{135 + 150 + 280 + 135 + 300}{30}\\\\=\frac{1000}{30}\\\\= 33. 33[/tex]

Answer:

d.  1.5%

Step-by-step explanation:

Given - The track and field coach records Ian's 400-meter race times during three practices.

Practice        1          2           3

Time (s)         63       60        58

To find - How much greater was the percent of change from Practice 1 to Practice 2 than from Practice 2 to Practice 3? Round to the nearest tenth.

a. 7.9%

b.  4.8%

c.  3.3%

d.  1.5%

Proof -

% change from Practice 1 to Practice 2 change = [tex]\frac{60 - 63}{63}. 100[/tex]%

                                                                           = [tex]-\frac{3}{63}.100[/tex]% = - 4.761904762 %

⇒% change from Practice 1 to Practice 2 change = - 4.762 %

Now,

% change from Practice 2 to Practice 3 change = [tex]\frac{58 - 60}{60}. 100[/tex]%

                                                                           = [tex]-\frac{2}{60}.100[/tex]% = - 3.334 %

⇒% change from Practice 2 to Practice 3 change = - 3.3334 %

So,

- 4.461904762% - (- 3.3334%) = -4.461904762 + 3.3334 % = -1.4285 % ≈ 1.5%

∴ we get

Value = 1.5%

The correct option is - d.  1.5%

Answer:

1. C - Directly Proportional Graph

2. D - Square Root Graph (I don't know, I just eliminated it from all the other options xD)

3. A - Exponential Graph

4. B - Reciprocal Graph

Answer:

A. Rate of Change: 25/1

B. Initial Value: 100

C. Y=25x+100

D. After 6 months the cost is 250$

E. 475=25x+100

475=25x+100

375=25x

x=15

So E. is 15 months

Step-by-step explanation:

Answer:

first we fisson in three regtangles. and we gain 6 cm to 3cm regtangles. they have the same width and length.

and we find their area. we multiplay 6cm and 3cm. the result is 18 cm square. and they have the same area.

lastly we find the value of the picture by find the sum of three regtangels.18cm square+18cm square+18cm square=

54cm square. fainally the answer is 54cm square.

Answer:

No Idea what the answer is...

Answer:

Let get small number is x and large number is y.

The difference between two numbers is 308328.

ie. y- x = 308328.

If the smaller number is

6524.

So, x= 6524.

Hence,

y - x = 308328

y- 6524 = 308328

y = 308328 + 6524

y = 314852

Step-by-step explanation:

Answer: 67.5 cm

Step-by-step explanation:

Jason has 4 lengths of ropes

first is [tex]3\ in.\approx 7.5\ cm[/tex]

second is [tex]15\ cm[/tex]

Third is [tex]0.3\ m\approx 30\ cm\quad [\text{1 m = 100 cm}][/tex]

fourth is [tex]0.5\ ft\approx 6\ in.\approx 15\ cm\quad [\text{1 ft=12 in.}][/tex]

the total length of rope is the sum of four lengths

[tex]\Rightarrow 7.5+15+30+15=67.5\ cm[/tex]

Answer: 161

Step-by-step explanation:

From the question, the rule is that we start with 1, multiply the previous number by 3 then add 2 to the result to get the next number.

Based on the numbers already given such as 1, 5, 17, the 4th number will be:

= (17 × 3) + 2

= 51 + 2

= 53

The 5th number will be:

= (53 × 3) + 2

= 159 + 2

= 161

Answer:

1st one, 4th one, and 5th one

Step-by-step explanation:

Answer:

red, blue and purple

hey There!

for the first one

2*2=4

4*2=8

8*2= 16 so blue is correct

8*8=64 so cyan is not correct

2^8=256 so yellow is not correct

4*4=16 so red is correct

2^4 is the same as 2*2*2*2 which equals 16 so purple is also correct

Answer:

11699 square centimeters

Step-by-step explanation:

In ΔIJK, j = 800 cm, k = 240 cm and ∠I=173°. Find the area of ΔIJK, to the nearest square centimeter.

When given two sides of a triangle and an angle, the area of the triangle is calculated as:

1/2jksintheta

theta = 173°

Hence:

Area of triangle =

1/2 × 800 × 240 × sin 173

= 11699.456967 square centimeters

Approximately = 11699 square centimeters

Answer:

y = - [tex]\frac{3}{2}[/tex] x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = [tex]\frac{0-3}{2-0}[/tex] = - [tex]\frac{3}{2}[/tex]

The line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = - [tex]\frac{3}{2}[/tex] x + 3 ← equation of line
