Answer: 280 minutes

Step-by-step explanation:

Given

Expression is  [tex]7\times (15+25)[/tex]

Apply distributive law i.e.

[tex]a(b+c)=a\cdot b+a\cdot c[/tex]

[tex]\Rightarrow 7(15+25)=7\cdot 15+7\cdot 25\\\Rightarrow 7(15+25)=105+175=280[/tex]

Thus, theo dog took 280 minutes each week

Answer:

Answer D 88%

Step-by-step explanation:

To figure this question out we first need to find 1% of 25, which is .25 and then we need to find what percentage 3 is of 25, and so 12 x .25 = 3 which means 3 is 12% of 25, now just subtract it from 100% and we get 88%

Answer:

25.7 feets

Step-by-step explanation:

From the diagram attached, we could use trigonometry to obtain the height,h :

Using the trigonometric relation :

Sin θ = opposite / hypotenus

Opposite = h

Hypotenus = 26 feets

Sin 81° = h / 26

Height, h = 26 * sin 81°

h = 26 * 0.9876883

h = 25.679

Height, h = 25.7 feets

Answer:

1/6 of a yard

Step-by-step explanation:

Length of the board = 5/6 yard

He needs to cut the board into 5 equal sections.

Length of each section = length of the board ÷ number of sections

= 5/6 ÷ 5

= 5/6 × 1/5

= (5*1)/(6*5)

= 5/30

= 1/6

Length of each section = 1/6 of a yard

Answer:

A

Step-by-step explanation:

Slope-intercept form: y=mx+b

2x+3y = 12

3y = 12-2x

y = (12-2x)/3

y = 4-2/3x

Here we can see that the slope is -2/3 and y-intercept 4. We already got the answer so we dont need to try the other options.

Given:

Consider [tex]AB\parallel DE[/tex] in triangle ABC and [tex]AD=8,DC=3.2,BE=9[/tex].

To find:

The length of BC.

Solution:

Basic proportionality theorem (BPT): If a line intersect the two sides of triangle and parallel to the third side, then that line intersects the other two sides proportionally.

Using Basic proportionality theorem, we get

[tex]\dfrac{AD}{DC}=\dfrac{BE}{EC}[/tex]

[tex]\dfrac{8}{3.2}=\dfrac{9}{EC}[/tex]

On cross multiplication, we get

[tex]8\times EC=9\times 3.2[/tex]

[tex]EC=\dfrac{28.8}{8}[/tex]

[tex]EC=3.6[/tex]

Now,

[tex]BC=BE+EC[/tex]

[tex]BC=9+3.6[/tex]

[tex]BC=12.6[/tex]

Therefore, the length of side BC is 12.6 units.

Answer:

$8

Step-by-step explanation:

To find 10% of a number, move the decimal point over by one. Since the number is a whole the decimal point looks like this    

$40.00

Move it once to get 10% which is 4. Then multiply it by 2 to get 20%.

Answer:

1.False

2. True

3.) True

4. False

5.) False

6.) True

Step-by-step explanation:

1.)

Range = maximum - minimum

New year's eve :

Maximum = 22 ; minimum = 3

Range = 22 - 3 = 19

2.)

Median for Thanksgiving = 17

50% up to 17 ;hence the remaining 50% is also 17 and above

4.)

IQR for Thanksgiving

Q3 - Q1

23 - 12 = 11

5.)

The median number of people at new year's eve for dinner was 7 (line in between the box)

6.)

3/4th of new year eve's dinner = Q3 = 15

1/4 = Q1 ; have up to 5 people

Therefore ; the remaining (1 - 1/4) = 3/4 have 5 and above

Answer:

1.False

2. True

3.) True

4. False

5.) False

6.) True

Step-by-step explanation:

Refer to the equations for a limaçon:

y=a+bcos∅ (horizontal line of symmetry) and y=a+bsin∅ (vertical line of symmetry) where a/b determines the type of limaçon.

This is an inner loop limaçon because 36/70<1, so its horizontal axis intercepts are 36 and -36 (marked in red) and its vertical axis intercepts are 0, 36+70=106 and 70-36=34 (marked in green)

Answer:

The initial number of video views was more than the initial number of site visits, and the number of video views grew by  a smaller factor than  the number of site visits.  The difference between the total number of site visits and the video views after 5 weeks is  20,825

Step-by-step explanation:

the initial video view was 5120 and the initial number of site visits were 4800, so the initial video view was more than.

The video views grew by 5/4 and the number of site visits grew by 3/2, and since 3/2 is > 5/4, the video views grew by a smaller factor than the number of site visits.

the result for the video views after 5 weeks is 15,625 and the site visits after 5 weeks is 36450, so 36450-15,625=20,825

so this satisfices the ration 4:9

Answer:

Amir : 20 sweets and Rita : 45 sweets

Step-by-step explanation:

Rita has 25 more in all answers. to get the answer, this is to see which one : 4:9 ; 20:45.

we multiply 4 and 45 and 9 and 20. if we multiply them, both answers are 180. this means it is equal and that is the answer.

C. Test each substance with red litmus paper.

Step-by-step explanation:

C is the correct answer because when you apply a base with a red litmus paper the outcome color should result in blue.

The best approach best investigate whether substances are basic is to test each substance with red litmus paper.

In general, bases are substances that can neutralise a small amount of acid. Ammonia and sodium carbonate are both bases even though neither of them includes OH groups.

When in contact with basic chemicals, red litmus paper turns blue instead of red. Thus we should use red litmus paper to test the basicity of home items.

Hence, the test each substance with red litmus paper.
