Answer:

(9159 / 7 = 1308.429)

Step-by-step explanation:

Simply multiply the last digit by 2 and then subtract the product from the remaining digits.

If that difference is divisible by 7, then 9159 is divisible by 7.

The last digit in 9159 is 9 and the remaining digits are 915. Thus, the math to determine if 9159 is divisible by 7 using our alternate method is:

915 - (9 x 2) = 897

Since 897 is not divisible by 7, 9159 is also not divisible by 7.

Therefore, the answer to "Is 9159 Divisible By 7?" is no.

(9159 / 7 = 1308.429)

Question 1
Lunna [17]

Answer:

1)x=21.33

2)Height of tree is 20 m

Step-by-step explanation:

Question 1

ΔABC ≈ΔADE

Property of similar triangles :Corresponding sides of similar triangles are all in the same proportion

So,\frac{AB}{AD}=\frac{BC}{DE}\\\frac{AB}{AB+BD}=\frac{BC}{DE}\\\frac{12}{12+6}=\frac{x}{32}\\\frac{12}{18}=\frac{x}{32}\\\frac{12}{18} \times 32 =x\\21.33=x

Question 2: Find the height of tree

ΔDEF ≈ΔDHI

Property of similar triangles :Corresponding sides of similar triangles are all in the same proportion

So,\frac{DE}{DH}=\frac{EF}{HI}\\\frac{3}{30}=\frac{2}{HI}\\HI=\frac{2 \times 30}{3}\\HI=20

Hence The height of tree is 30 m

The length of a rectangle is shown below:
bazaltina [42]

Answer:

  • C(3, -3), D( -2, -3)

Step-by-step explanation:

<u>The coordinates of A and B are:</u>

  • A( -2, 3) and B(3, 3)

<u>The distance AB is:</u>

  • AB = 3 - (- 2) = 5 units

<u>The rectangle wit the area of 30 units² should have the other dimension:</u>

  • AC = BD = 30/5 = 6 units

<u>Since D and C are below of the A and B, their coordinates will be same on x-axis but different on y-axis:</u>

  • D = (-2, 3 - 6 = - 3) = (- 2, - 3)
  • C = (3, 3 - 6 = - 3) = (3, - 3)

Correct choice is B

The table shows ordered pairs for a polynomial function, f. What is the degree of f?
Kazeer [188]

Answer:

5th degree

Step-by-step explanation:

To solve this problem/table, you have to find the differences in the f(x) side of the table until the differences between the numbers are the same, and then you have your degree. Look at the image attached for more sense

The head of the math department is studying the student scores on last year's basic skills test. She has determined the median s
avanturin [10]

Answer:

25%

Step-by-step explanation:

The median score of 70% indicates half of the student scored less than 70%.

An upper quartile of 85% means 3/4 of the students scored less than 85% or, stated in another way, 1/4 of the students scored above or equal to 85%.

From sentence 1, 50% of the students scored below 70%.

From sentence 1, 75% of the students scored below 85%.

The percentage that score between 70% and 85% is 75% - 50% = 25%
