Answer:35

If you want to get the area

Times the ten by seven then divide the sum

Question

Factor completely 56a2b3 − 35ab. 7ab(8ab2 − 5)
7a(8b2 − 5ab)
Prime
7a(8ab3 − 5b)

Solution 1

**Answer:**

**7 ab ( 8 ab² - 5 ) .**

**Step-by-step explanation:**

Given : 56 a²b³ − 35 ab.

To find : Factor completely.

Solution : We have given 56 a²b³ − 35 ab.

Taking 7ab common form both terms .

7 ab ( 8 ab² - 5 ) .

**Therefore, 7 ab ( 8 ab² - 5 ) .**

Solution 2

A.

Both numbers have a factor of 7ab. Pull that out by dividing.

Both numbers have a factor of 7ab. Pull that out by dividing.

Question

How can you determine the difference between an arithmetic and geometric sequence if you are given the first 4 terms of the sequence?

Solution 1

**Sample response: **First identify the pattern of the sequence. If there is a common difference between the terms, it is an arithmetic sequence. If there is a common ratio between the terms, it is a geometric sequence.

Answer on edge nuity : )

Solution 2

Compute successive differences of the terms.

If they are all the same, the sequence is arithmetic and the common difference is the difference you have found.

If successive pairs of differences have the same ratio, the sequence is geometric and the common ratio is the ratio you have determined.

Example of arithmetic sequence:

1, 3, 5, 7

Successive differences are 3-1 = 2, 5-3 = 2, 7-5 = 2. All the differences are 2, which is the common difference of the sequence.

Example of geometric sequence:

1, -3, 9, -27

Successive differences are -3-1 = -4, 9-(-3) = 12, -27-9 = -36. These are not the same, so the sequence is not arithmetic. Ratios of successive pairs of differences are 12/-4 = -3, -36/12 = -3. These are the same, so the sequence is geometric with common ratio -3.

If they are all the same, the sequence is arithmetic and the common difference is the difference you have found.

Question

A store spends 30% of its budget on maintenance. Its yearly budget is $150,000. Hiw much is spent on maintenance

Solution 1

45000 because 150000*0.3. 0.3 is 30% in decimal form

Solution 2

30% = 30/100 = 3/10.

3/10 of 150000 is

45000. :)

3/10 of 150000 is

45000. :)

Question

Jim is climbing a mountain that has a base 150 feet above sea level. If he climbs 233 feet then descends into a cave 64 feet, how far above sea level is Jim? A. 86feet, B. 169 feet, C. 214 feet, D. 319 feet.

Solution 1

We know that

1) Jim is climbing a mountain that has a base -----> 150 ft above sea level

2) He climbs 233 ft------------> 150 ft+233 ft----> 383 ft above sea level

3) He descends into a cave 64 ft------> 383 ft-64 ft----> 319 ft above sea level

**the answer is**

**the option **

**D. 319 feet.**

1) Jim is climbing a mountain that has a base -----> 150 ft above sea level

2) He climbs 233 ft------------> 150 ft+233 ft----> 383 ft above sea level

3) He descends into a cave 64 ft------> 383 ft-64 ft----> 319 ft above sea level

Question

What is the amplitude of y=1/2sin2x

Solution 1

The multiplier of the sine function is its amplitude: 1/2.

Question

Alice makes 8 bracelets. there are 4 red beads on each bracelets. witch number sentence shows the total number of beads used?

Solution 1

The correct answer is 32

Solution 2

Not sure what you mean by # sentence

But 8 bracelets times 4 red beads equals 32 beads in total

8 * 4 = 32

But 8 bracelets times 4 red beads equals 32 beads in total

8 * 4 = 32

Question

Steve puts only dimes and quarters into his piggy bank. Right now he has five more dimes than quarters there, and they make exactly $74! How many quarters and how many dimes are there in Steve’s piggy bank?

Solution 1

X - quarters, x+5 - dimes.

$74=7400 cents

Then

(25x+10(x+5))=(25x+10x+50)=**(35x+50)** cents.

35x+50=7400

35x=7400-50

35x=7350

x=7350/35

**x=210 quarters**

**x+5**=210+5=**215 dimes**

**210 quarters and ****215 dimes**

$74=7400 cents

Then

(25x+10(x+5))=(25x+10x+50)=

35x+50=7400

35x=7400-50

35x=7350

x=7350/35

Solution 2

**Answer:**

**215 dimes and 210 quarters**

**Step-by-step explanation:**

Quarters are x

dimes are x+5

.25x+.10(x+5)=74

.25x+.10x+.5=74

.35x=73.5

x=210 quarters or $52.50

x+5=215 dimes or $21.50

Add to $74.

Question

Which solution to the equation (1/x-1)=(x-2/2x^2 -2) is extraneous? a. x=1 and x=-4
b. nether x=1 or x=-4
c. x=1
d. x=-4

Solution 1

Any "solution" that makes a denominator zero will be extraneous.

The appropriate choice is ...

c. x=1

_____

This can be solved without extraneous solutions by subtracting the right side.

(2(x +1) -(x -2))/(2(x -1)(x +1)) = 0

(x +4) = 0 . . . . . . . . . . . . . . . . . . . . . multiply by the denominator

x = -4 . . . . . . . . . . . . . . . . . . . . . . . . subtract 4

The appropriate choice is ...

c. x=1

_____

This can be solved without extraneous solutions by subtracting the right side.

(2(x +1) -(x -2))/(2(x -1)(x +1)) = 0

(x +4) = 0 . . . . . . . . . . . . . . . . . . . . . multiply by the denominator

Question

The hyperbola with center at (4, 5), with vertices at (0, 5) and (8, 5), with b = 2.

Solution 1

The standard form of hyperbola is:

(x-h)²/a²-(y-k)²/b²=1

center:(4,5)

Length of the horizontal transverse axis: 8-5=3=2a

thus

a=3/2

a²=9/4

b=2

b²=4

Hence the equation will be:

(x-4)²/(9/4)-(y-5)²/4=1

simplifying this we get:

[4(x-4)²]/9-(y-5)²/4=1

(x-h)²/a²-(y-k)²/b²=1

center:(4,5)

Length of the horizontal transverse axis: 8-5=3=2a

thus

a=3/2

a²=9/4

b=2

b²=4

Hence the equation will be:

(x-4)²/(9/4)-(y-5)²/4=1

simplifying this we get:

[4(x-4)²]/9-(y-5)²/4=1

Solution 2

**Answer:**

**Step-by-step explanation:**

The correct answer is (x-4)^2/16 - (y-5)^2/4 = 1
