Answer:

x=2*2 4/5

Step-by-step explanation:

: Martin had 2 4/5 pounds of grapes left.

So x=2*2 4/5

x=2* 14/5

x=28/5

x=5 3/5

The expression shows the pounds of grapes Martin has if he doubles his current amount of grapes. x=2*2 4/5

Answer:

  (a)  twenty-eight ninths, square root of nineteen, cube root of eighty-eight

Step-by-step explanation:

When ordering a list of numbers by hand, it is convenient to convert them to the same form. Decimal equivalents are easily found using a calculator.

The attachment shows the ordering, least to greatest, to be ...

  \(\dfrac{28}{9}.\ \sqrt{19},\ \sqrt[3]{88}\)

__

Additional comment

We know that √19 > √16 = 4, and ∛88 > ∛64 = 4, so the fraction 28/9 will be the smallest. That leaves us to compare √19 and ∛88, both of which are near the same value between 4 and 5.

One way to do the comparison is to convert these to values that need to have the same root:

  √19 = 19^(1/2) = 19^(3/6) = sixthroot(19³)

  ∛88 = 88^(1/3) = 88^(2/6) = sixthroot(88²)

The roots will have the same ordering as 19³ and 88².

Of course, these values can be found easily using a calculator, as can the original roots. By hand, we might compute them as ...

  19³ = (20 -1)³ = 20³ -3(20²) +3(20) -1 = 8000 -1200 +60 -1 = 6859

  88² = (90 -2)² = 90² -2(2)(90) +2² = 8100 -360 +4 = 7744

Then the ordering is ...

  28/9 < 19³ < 88²   ⇒   28/9 < √19 < ∛88

Answer:

the ordering is

28/9 < 19³ < 88²   ⇒   28/9 < √19 < ∛88

Answer:

The answer is -48

Step-by-step explanation:

First step is to follow PEMDAS

So we start solving whatever is in the ( )

4^2 is in the ( ) 4^2 = 16 then we multiply

-3 * 16 which is -48

-

We get x = -3 and y = 2 on solving 2x + 5y = 4; 2x - y = -8

Let's find y from the second equation in terms of x:

2x - y = -8

-y = -2x - 8

y = 2x + 8

Now, we may enter the following expression in place of y in the first equation:

2x + 5y = 4

2x + 5(2x + 8) = 4

Simplifying this equation, we get:

12x + 40 = 4

Subtracting 40 from both sides, we get:

12x = -36

Dividing both sides by 12, we get:

x = -3

Now we can substitute this value of x into our expression for y:

y = 2x + 8 = 2(-3) + 8 = 2

Hence, x= -3 and y= 2 are the answers to the system of equations.

The complete question can be:

2x + 5y = 4

2x - y = -8

solve for x and y

The expressions -5(-4x + 9) and -5(x - 5x + 9) are equivalent to -5x - 15 + 25x - 30. Option A and C

We can simplify the supplied expression and contrast it with the other possibilities to find which expressions are equivalent to -5x - 15 + 25x - 30.

We can combine similar words starting with -5x - 15 + 25x - 30, for example:

-5x + 25x - 15 - 30 = 20x - 45

Let's now examine each choice:

-5(-4x + 9):

After dividing the -5, we obtain:

20x - 45 = -5(-4x) + 5(9)

The provided expression and this expression are interchangeable.

−5(x – 3 + 5x – 6):

Once the -5 is distributed, we obtain: 20x - 45 = -5x + 15 - 25x + 30.

The given expression and this expression are not comparable.−5(x - 5x + 9):

When we condense the equation between the brackets, we obtain:

20x - 45 = -5(-4x + 9)

The provided expression and this expression are interchangeable.

-5(6x - 9):

The result of distributing the -5 is: 20x - 45 = -30x + 45

The provided expression and this expression are not equal.

-5(x + 3 - 5x - 6):

By condensing the expression in the parentheses, we arrive at the following: 20x - 45 = -5(-4x - 3)

The provided expression and this expression are not equal.

-5(x + 3 - 5x + 6): When the expression between the brackets is simplified, we get:

20x - 45 = -5(-4x + 9)

The provided expression and this expression are interchangeable.

The formulae -5(-4x + 9) and -5(x - 5x + 9) therefore equal -5x - 15 + 25x - 30.

The proper answers are A and C.

Step-by-step explanation:

The correct option is A. 0.156. The number (1.092×10¹) is 156 times larger than number (7×10⁻¹).

For the given number;

The number 1.092×10¹ can be written as; 10.92 after multiplication with 10.

Similarly, the number 7×10⁻¹ can be written as 0.7 after diving with 10.

A zero has the same meaning as the vertex.

The point where two lines meet forming an angle or set of angles is referred to as a vertex. This can also be called a point of origin especially when considering the axis of a Cartesian coordinate.

The vertex can be taken as zero since it is referred to as the point of origin. This is different to the axis of symmetry; as the axis of symmetry is one that splits a given plotted points i.e. a graph into two equal parts.

The half-life of the given exponential function is of 346.57 years.

It is the value of t when A(t) = 0.5A(0).

In this problem, the equation is:

\(A(t) = A(0)e^{-0.002t}\).

In which t is measured in years.

Hence the half-life is found as follows:

\(0.5A(0) = A(0)e^{-0.002t}\)

\(e^{-0.002t} = 0.5\)

\(\ln{e^{-0.002t}} = \ln{0.5}\)

\(0.002t = -\ln{0.5}\)

\(t = -\frac{\ln{0.5}}{0.002}\)

t = 346.57 years.

Answer:

$36.69

Step-by-step explanation:

Okay, so let's first write the equation:

2.59*10 + 3d = 135.97

Now, let's work on isolating d by first simplifying the equation:

25.9 + 3d = 135.97

25.9 + 3d - 25.9 = 135.97 - 25.9

3d = 110.07

3d/3 = 110.07/3

d = 36.69

Okay, now let's check:

2.59*10 + 3*36.69  = 135.97

25.9 + 110.07 = 135.97

135.97 = 135.97

Okay, so so it costs $36.69 per pair of shoe.

I agree with both Priya's and Han's equations.

To determine if either Priya or Han equation is correct, we can substitute the coordinates of the given point (1,2) into each equation and check if the equation holds true.

For Priya's equation, y - 2 = (1/3)(x - 1), substituting x = 1 and y = 2:

2 - 2 = (1/3)(1 - 1)

0 = 0

The equation holds true, so Priya's equation is correct.

For Han's equation, 3y - x = 5, substituting x = 1 and y = 2:

3(2) - 1 = 5

6 - 1 = 5

5 = 5

The equation also holds true, so Han's equation is correct.

Both Priya's and Han's equations are valid equations of the line with a slope of 1/3 passing through the point (1,2). The equations have different forms, but they are algebraically equivalent and represent the same line. Therefore, I agree with both Priya's and Han's equations.

Answer:

We are told that circle C has center (-4, 6) and a radius of 2.

We are told that circle D has center (6, -2) and a radius of 4.

If we move circle C's center ten units to the right and eight units down, the new center would be at (-4 + 10), (6 - 8) = (6, -2). So step 1 in the informal proof checks out - the centers are the same (which is the definition of concentric) and the shifts are right.

Let's look at our circles. Circle C has a radius of 2 and is inside circle D, whose radius is 4. Between Circle C and Circle D, the radii have a 1:2 ratio, as seen below:

If we dilate circle C by a factor of 2, it means we are expanding it and doubling it. Our circle has that 1:2 ratio, and doubling both sides gives us 2:4. The second step checks out.

Translated objects (or those that you shift) can be congruent, and dilated objects are used with similarity (where you stretch and squeeze). The third step checks out.

Thus, the argument is correct and the last choice is best.

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180° , that is

Step-by-step explanation:

Let's call the pieces 5x, 3x, and 7x respectively. The longest (7x) and shortest (3x) pieces had a difference of 64 cm. Therefore, 7x - 3x = 64 → 4x = 64 → x = 16 cm. We know that the longest piece is 7x, so its length is 7 * 16 = 112 cm. As for the total length of the cord, we can express it as 5x + 3x + 7x = 15x, which is 15 * 16 = 240 cm. Hope this helps!

1) 112 m

Answer:

2) 240 m

Step-by-step explanation:

Let the length of pieces be 5x, 3x and 7x m.

Where 3x is the shortest piece and 7x is the longest piece.

According to the given condition:

7x - 3x = 64

4x = 64

x = 64/4

x = 16 m

1) Length of longest piece = 7x = 7* 16 = 112 m

2) length of the Electrical cord in meters before it was cut = 5x + 3x + 7x = 15x = 15*16 =240 m
