Lilly has read seven-eighths of her book and is on page 147. How many pages does lilly have left to read?

Answer would be the third option.

Area of a triangle is half of the base times the height. A=(b·h)/2

In the third option the height is 8 ft. and base is 6 ft. which when multiplied together gets you 48. Half of that is 24.

Answer:

14/5 or 2 4/5

Step-by-step explanation:

7 3/5 = 38/5

4 4/5 = 24/5

38/5 - 24/5 = 14/5 = 2 4/5

Answer: 1.6M kilometers, 8 kilometers

Step-by-step explanation:

Kilometers per mile times miles gives kilometers.

(1.6 kilometers / mile) × M miles = 1.6M kilometers

5×1.6 is 8

We are given that AB ≅ CB and AD ≅ CD.

We know that BD ≅ BD, so ΔABD ≅ ΔCBD by SSS.

Then ∠1 ≅ ∠2 by CPCTC; and ∠3 ≅ ∠4, also by CPCTC.

Since ∠1 ≅ ∠2, BD is the bisector of (∠1+∠2) = ∠ABC.

Since ∠3 ≅ ∠4, BD is the bisector of (∠3+∠4) = ∠ADC.

From (5), we know BD is the angle bisector of ∠ABC. ΔABC is isosceles, so the bisector of the apex angle is also an altitude and median. That is, point M on BD and AC must be the midpoint of AC by the definition of a median.

Answer:

Sam picked 27

Step-by-step explanation:

41-8=33

33+27=60

Answer:

27.

Step-by-step explanation:

So there was 41 peaches, and they sold 8 so that's 41 - 8 which is 33 peaches. But now there is 60, so you do 60 - 33 gives you how many were picked and 60 - 33 is 27.

Step-by-step explanation:

The number of bags that can be filled completely is 105 and the 3 rocks will be left over.

Division is the process of dividing a number by a given number.

Given that, the number of rocks is 1578 and the number of rocks in each bag is 15.

To find the number of bags, divide the number of total rocks by the number of total rocks in each bag:

1578/15

= 105.2

≈ 105

Now, the number of rocks in 105 bags is:

105 ×15

= 1575

So, the number of rocks left is:
1578 - 1575

= 3

Hence, the number of bags that can be filled completely is 105 and the 3 rocks will be left over.

Answer:

the units of volume are always cubic units

To simplify the expression (r⁻³ s² t)⁴, the power of a power rule is used to obtain the result r⁻¹² s⁸ t⁴.

To simplify the expression (r⁻³ s² t)⁴, we apply the power of a power rule, which states that (ab)c = ab*c. Using this rule, we raise each factor within the parentheses to the fourth power:

Therefore, the simplified expression is r⁻¹² s⁸ t⁴.

Answer:

Joey needs to eat 7 hot dogs per minute to break his own record in next 9 minutes.

Step-by-step explanation:

Joey needs more than 72 hot dogs in 10 minutes to break his own record.That means Joey needs to eat at least 73 hot dogs in 10 minutes.

After 1 minute Joey has eaten = 10 hot dogs.

In remaining 9 minutes balance hot dogs = 73-10 =63

Therefore per minute hot dogs to be eaten = 63/9 =7

So answer is 7 hot dogs per minute to be eaten.

Joey needs to eat  7.00 hot dogs per minute for the next 9 minutes to break his own record.

To break his record, Joey Chestnut needs to eat more than 72 hot dogs in 10 minutes. After the first minute, he has already eaten 10 hot dogs. So, he has 9 minutes left to eat the remaining hot dogs needed to break the record, which is 72 - 10 = 62 hot dogs.

To find out how many hot dogs per minute Joey needs to eat for the next 9 minutes, we divide the remaining number of hot dogs by the remaining time:

Hot dogs per minute = Remaining hot dogs / Remaining time

Hot dogs per minute = 62 hot dogs / 9 minutes

Hot dogs per minute ≈ 6.89 hot dogs per minute

Therefore, Joey needs to eat  7.00 hot dogs per minute for the next 9 minutes to break his own record.

It's important to note that Joey needs to eat more than this calculated rate per minute to ensure he breaks his record, as he cannot consume a fraction of a hot dog. So, he should aim to eat at least 7 hot dogs per minute to secure his victory.

Look at the picture.

ΔABC and ΔDAC are similar. Therefore the sides of the triangles are in proportion:

[tex]\dfrac{AC}{BC}=\dfrac{DC}{AC}[/tex]

AC = x

BC = 5 + 4 = 9

DC = 4

Substitute:

[tex]\dfrac{x}{9}=\dfrac{4}{x}[/tex]          cross multiply

[tex]x^2=(9)(4)\\\\x^2=36\to x=\sqrt{36}\\\\\boxed{x=6\to C)}[/tex]

Answer: x = 9 (choice D)

Assuming this is a geometric kite, then this means that triangle ABD is a reflection over the line BD to get triangle BCD. Furthermore, this points to AB and BC being the same length

AB = BC

3x - 5 = 22 .... substitution

3x - 5+5 = 22+5 .... add 5 to both sides

3x = 27

3x/3 = 27/3 ..... divide both sides by 3

x = 9

Answer:

[tex]x+1[/tex] meters.

Step-by-step explanation:

Let L be the length of rectangle.

We have been given that the rectangle has an area of [tex]x^{2}-6x-7[/tex] square meters and a width of [tex]x-7[/tex] meters.

Since we know that area of rectangle is the product of its length and width.

[tex]\text{Area of rectangle}=\text{Width* Length}[/tex]

[tex]\text{ Length}=\frac{\text{Area of rectangle}}{\text{Width}}[/tex]

To find the length of our given rectangle we will divide area of rectangle by width of our rectangle.

[tex]L=\frac{x^2-6x-7}{x-7}[/tex]

Let us factor out our numerator by splitting the middle term.

[tex]L=\frac{x^2-7x+x-7}{x-7}[/tex]

[tex]L=\frac{x(x-7)+1(x-7)}{x-7}[/tex]

[tex]L=\frac{(x-7)(x+1)}{x-7}[/tex]

Upon cancelling out x-7 from numerator and denominator we will get,

[tex]L=(x+1)[/tex]  

Therefore, the length of our rectangle will be [tex]x+1[/tex] meters.

Step-by-step explanation:

Answer:

The actual room measurement is 15 yrds by 10 yrds

Then the length is 15 yrds

Step-by-step explanation:

1 feet is equal to 0.3333 yards

The room measure 3 by 2 feet

Scale on blue print 1 ft to 5 yrds.

That's is to say for every ft in the Blue print...it is 5 yrds real.

So it's multipling factor bis five.

The actual measurement will be

5*(3 by 2) yrds

The actual measurement is 15 yrds by 10 yrds .

But the length is 15 yrds and breadth is 10 yrds

Answer:

yes

Step-by-step explanation:

for the sticks to form a right triangle, the 3 sticks' lengths must comply w the Pythagoras theorem: hypothesis^2 = first side^2 + second side^2

hypothesis is the longest length so its 10

10^2 = 100 = 36 + 64 = 6^2 + 8^2

so the 3 sticks will form a right triangle

Answer:

6^2+8^2=10^2 so yes

Step-by-step explanation:

In order to test a triangle with lengths 6, 8 and 10 inches is right-angle or not, the Pythagoras equation should be used: a^2+b^2=c^2.

As 6^2+8^2=10^2 so yes, the three sticks will form a right-angle triangle.

Answer:

sqrt(-80) = 4sqrt(5)i

Step-by-step explanation:

Likely a list of answers should be provided. There are all kinds of possible answers (well 2 perhaps).

Begin by factoring 80 into prime factors.

80: 2*2*2*2*5

For ever pair of 2s, one can be taken outside the square root sign. The other one just disappears.

sqrt(80) = sqrt(2 * 2 * 2 * 2 * 5)

For every pair 2 is taken out of the root sign and the other forgotten

sqrt(2 * 2 * 2 * 2 * 5) = 2 * 2 * sqrt(5) = 4 sqrt(5)

The sqrt(-80) = 4sqrt(5)*sqrt(-1)

There is no real number that can be written as the sqrt(-1). So a number has been defined into existence. sqrt(-1) = i It's a definition, not a real number.

So the end result is sqrt(-80) = 4sqrt(5)i

Answer:

c

Step-by-step explanation:

Option (C) No; because x and y could be additive inverses of each other is correct.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that:

The expression is x + y

The expression can be defined as the combination of constants and variables with mathematical operators.

If x + y is rational, must x and y each can be or cannot be rational because x and y could be additive inverses of each other.

As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

Thus, option (C) No; because x and y could be additive inverses of each other is correct.

Answer:  The correct option is (B) -7.

Step-by-step explanation:  We are given to select the correct values of x that make the following rational expression undefined :

[tex]E=\dfrac{16-x}{7+x}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We know that

a rational expression is undefined at the points where the denominator becomes zero.

Therefore, the expression (i) will become undefined when

[tex]7+x=0\\\\\Rightarrow x=-7.[/tex]

Thus, the required value of x where the given expression is undefined is -7.

Option (B) is CORRECT.
