jacob copies 30% of a document which is 8 pages

we can solve this using cross multiplication

30 %       :        8

100%      :         x

30%x = 100%*8

30% x = 8

x = 8/ 30%

x = 26.667

Answer:

Perpendicular lines are lines that cross one another at a 90° angle. They have slopes that are opposite reciprocals of one another. Unlike parallel lines that never touch, perpendicular lines must intersect.

Therefore, the shape with 2 lines that don't intersect/touch each other, is the shape that does not have perpendicular lines.

Answer:

[tex](fg)(7) = - 35[/tex]

Step-by-step explanation:

The given functions are:

[tex]f(x) = {x}^{2} - 14[/tex]

and

[tex]g(x) = 6 - x[/tex]

We want to to find

[tex](fg)(7)[/tex]

Note that:

[tex](fg)(x) = f(x) \times g(x)[/tex]

We substitute the functions to obtain:

[tex](fg)(x) = ( {x}^{2} -1 4 ) \times (6 - x)[/tex]

We now substitute x=7, to get:

[tex](fg)(7) = ( {7}^{2} -1 4 ) \times (6 - 7)[/tex]

This implies that

[tex](fg)(7) =( 49-1 4 ) \times (6 - 7)[/tex]

[tex](fg)(7) = 35 \times - 1 = - 35[/tex]

Answer:

x = 2

Step-by-step explanation:

[tex]4x + 6 = 2x + 10 \\ \\ 4x - 2x = 10 - 6 \\ \\ 2x = 4 \\ \\ x = \frac{4}{2} \\ \\ x = 2[/tex]

Answer:

No

Step-by-step explanation:

Apply the distributive property to 5(2x - 3y):

Multiply 5 by each term inside the parentheses.

5(2x - 3y) = 10x - 15y

The other expression is 10x - 10y.

The terms 10x in both expressions are equal.

Since the term -15y is not equal to the term -10y, the expressions are not equivalent.

  P(A & B) = 2/7

Answer: 4/7

Step-by-step explanation:

Answer:

30x^4−12x^3=6x^3(5x−2) = True

4x^2+10x=2x(2x+5) = True

100x^3+5=5x^3(20x+1) = False

8x^3−6x=2x^3(4−3x3) = False

Step-by-step explanation:

The statements which are true are 30x4−12x3=6x3(5x−2) ,  4x2+10x=2x(2x+5)  and  100x3+5=5x3(20x+1)

To determine which of the statements are true, we can simplify each equation and compare.

Option a :

30x4−12x3=6x3(5x−2): Factoring out the common term we can see this equation is true.
Option b:

4x2+10x=2x(2x+5): After simplifying both sides we find that 2x(2x + 5) = 4x2 + 10x, so statement (b) is true.

Option c:

100x3+5=5x3(20x+1): Attempt to simplify this equation as 5x3(20x + 1). Since this simplification holds, statement (c) is also true.

Option d:

8x3−6x=2x3(4−3x3): Simplifying the right side does not give us the left side; thus, statement (d) is false. The correct form would be 2x(4x2 - 3), assuming a typo in exponent notation.

The solution to the compound inequality is x > -2 and x < -5, or (-∞, -5) ∪ (-2, ∞).

To find the solution to the compound inequality, we need to solve the individual inequalities separately and then find the intersection of their solution sets.

The solution to the compound inequality is the intersection of the solution sets of the individual inequalities, so the solution is x > -2 and x < -5. To express this in interval notation, we write (-∞, -5) ∪ (-2, ∞).

Answer:

1 minute on the x-axis; 10 mph on the y-axis

Step-by-step explanation:

The distance between exit ramps is less than 6 miles and since you are traveling at 70 mph on the highway you should get there in less than 5 mins, so the scale on the x-axis should be 1 minute. Since you have 10 tick marks on the y-axis and will be going at a speed of 70 mph at some point, the scale on the y-axis should be 10 mph (100 mph total). A good scale would be 1 minute on the x-axis; 10 mph on the y-axis.

Answer:

1 minute on the x-axis; 10 mph on the y-axis

Answer:

The answer for addition one is 11 1/2. The answer for subtraction would be -5/6.

Hope this helps. Can I please get brainliest if possible?

The answer you are looking for is 11 and 1/2.

To find this answer, you must first add the fractions together. Before you do so, you must make sure they have a common denominator. So, multiply 1/3 by 2/2 to get 2/6. Now, add 2/6 and 1/6 to get 3/6. 3/6 simplified (divided by 3/3) is 1/2.

Next, add the whole numbers. 5 + 6 is 11. Thus making your final answer 11 and 1/2.

I hope this helps!

Answer:

a) 28 quarters

b) 14 quarters  

Step-by-step explanation:

We are given the following in the question:

Number of quarters = 20 quarters

Number of quarters in room = 40%

Total number of quarter in room =

[tex]=40\%\times (20)\\\\=\dfrac{40}{100}\times 20\\\\=8[/tex]

Thus, the total quarters taken to shopping =

[tex]=20 +40\%\times (20)\\\\=20+8\\=28[/tex]

Thus, 28 quarters were taken to shopping.

Quarter spent on shopping = 50%

Total number of quarter spent in shopping =

[tex]=50\%\times (28)\\\\=\dfrac{50}{100}\times 28\\\\=14[/tex]

Money left =

Money taken for shopping - Money spent

[tex]= 28-14\\=14[/tex]

Thus, we are left with 14 quarters after shopping.

Answer: [tex]x^{2} - 6x +6 = 0[/tex]

Step-by-step explanation:

The formula for finding quadratic equation is given as :

[tex]x^{2}[/tex] - sum of roots[tex](x)[/tex] + product of roots = 0

sum of roots implies :

(3-√3)+(3+√3) =6

product of roots implies :

(3-√3) x (3+√3) = 9 +[tex]3\sqrt{3}[/tex] - [tex]3\sqrt{3}[/tex] - 3

(3-√3) x (3+√3) = 6

substituting into the equation we have:

[tex]x^{2} - 6x +6 = 0[/tex]

Answer:

The answer would be 7ft.

Step-by-step explanation:

Let the radius of the cylinder be rft. and its height be hft. Again the radius of the larger cylinder is R ft and its height is H ft. Given h = 5 ft.

As the cylinders are similar we can say   [tex]R/r[/tex] = [tex]H/h[/tex]

Now the volume of the smaller cylinder is  πr²h = 125

and that of larger one is   πR²H = 343

SO  πR²H/πr²h = 343/125

⇒ H²/h² × H/h = 343/125

⇒ H³/h³ = 7³/5³

⇒ H/h = 7/5

⇒ H =  7/5 × h = 7/5 × 5 = 7ft

Use this formula to find the total interest [tex]I=\frac{P*R*T}{100}[/tex]

I stands for interest, P is principal, R is rate, and T is time.

Principle = £2300

Rate = 5%

Time = 4 years

[tex]\frac{2,300*5*4}{100} =\frac{46,000}{100} =460[/tex]

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)

Answer:

£460

Step-by-step explanation:

Simple interest =PRT/100

Where P = principal

R= rate

T = Time

Given

P= £2300

T= 4yrs

R = 5%

Interest = 2300 x 5 x 4/100

Multiply through

Interest = 46000/100

Interest = £460

Answer:-6x+12

Step-by-step explanation:-3 • 2x = -6x

-3 • -4 = 12. Distribute the -3 to both numbers in the parentheses

Answer:

$112

Step-by-step explanation:

Let [tex]v[/tex] be the usual speed, and [tex]t[/tex] be the usual time.

Following the equation [tex]s=vt[/tex], where s is the space, v is the velocity and t is time, we know that usually we have

[tex]200=vt[/tex]

But this time we were 10mph faster and it took one hour less, so we have

[tex]200=(v+10)(t-1)[/tex]

Since both right hand sides equal 200, they must equal each other:

[tex]vt=(v+10)(t-1)=vt+10t-v-10 \iff 10t-v-10=0 \iff v=10t-10[/tex]

Plug this value in the first equation and we have

[tex]200=vt=(10t-10)t \iff 10t^2-10t-200=0[/tex]

This equation has solutions [tex]t=-4,\quad t=5[/tex]. We can only accept positive solutions, so we have t=5. We finally deduce, again from the first equation,

[tex]200=5v \iff v=\dfrac{200}{5}=40[/tex]

Answer:

1,2,3,4,5,7

Step-by-step explanation:

1+2+3+4+5+7 = 22

Final answer:

Six different natural numbers that add up to 22 are 1, 2, 3, 4, 5, and 7. The process involved starting with the smallest natural numbers and then incrementally adjusting the sequence to arrive at the sum of 22.

Explanation:

The question asks to find six different natural numbers whose sum equals to 22. We can begin with the smallest natural numbers, knowing that 1 cannot be included because the sum of the next five natural numbers (2, 3, 4, 5, and 6) already exceeds 22. If we start with 2 and follow with the next smallest numbers (3, 4, 5, and 6), the sum would be 20, which is close but not quite the target sum. To reach the sum of 22, we need to replace one of these numbers with a slightly larger number while still maintaining the rule that every number must be different.

Let's replace the 6 with a 7, so our numbers are now 2, 3, 4, 5, and 7. If we sum these up (2 + 3 + 4 + 5 + 7), we get 21. We need to add one more number to reach 22. The smallest number we haven't used yet is 1, but adding 1 to our sequence would require us to adjust another number as follows: 1, 2, 3, 4, 5, and 7 add up to 22. Therefore, the six different natural numbers whose sum is 22 are 1, 2, 3, 4, 5, and 7.

Answer:

231 miles.

Step-by-step explanation:

Tom rented a truck with a base fee of 19.95. You will subtract this from the total since you just want to get the mileage.

Tom is getting charged .85 cents per mile driven.

Tom payed 216.30 subtotal minus the 19.95 base fee since we are trying to only see how many miles he drove.

(216.30-19.95=196.35) This will be total for each mile. All we need to do is divide to get the total of miles

(196.35÷.85= 231)

231 is the number of miles Tom drove.
