Answer:

[tex]8 + x = 25 \\ x = 25 - 8 \\ 17[/tex]

Answer: 82

Step-by-step explanation:

[tex] \frac{1}{3} (1632 + x) = 726[/tex]

[tex] \frac{1}{3} (x + 1632) = 726[/tex]

[tex] \frac{1(x + 1632)}{3} = 726[/tex]

[tex] \frac{x + 1632}{3} = 726[/tex]

[tex]3· \frac{x + 1632}{3} = 3·726[/tex]

[tex]x + 1632 = 3·726[/tex]

[tex]x + 1632 = 2178[/tex]

[tex]x + 1632 - 1632 = 2178 - 1632[/tex]

[tex]x =546[/tex]

So, the value of x is 546.

Answer:

What value of x is in the solution set of 3(x - 4) = 5x + 2?

Solution:

3(x - 4) = 5x + 2 [Given]

Using the distributive law of multiplication on LHS

3x - 12 = 5x + 2

By grouping the similar terms on either sides and solving for x, we get

3x - 5x = 2 + 12

- 2x = 14

Divide both sides by -2 (by division property of equality)

(- 2x/2 )= 14/2

-x = 7

Therefore, the value of x is -7.

Answer: 1130 grams.

Answer:

D

Step-by-step explanation:

We can first eliminate options A and B because they are both negative slopes and the graph shown is an increasing slope, meaning the answer is positive.

Next, we calculate the slope with the formula (y2 - y1) / (x2 - x1) to get 1/4.

1/4 is the slope.

Answer:

A.  [tex]p(x)=7x-2[/tex]

Step-by-step explanation:

Given function:

[tex]y=\dfrac{x+2}{7}[/tex]

Rearrange to make x the subject:

[tex]\implies 7y=x+2[/tex]

[tex]\implies x=7y-2[/tex]

Swap x and y:

[tex]\implies y=7x-2[/tex]

This is the inverse of the original function.

Therefore, the answer is A  [tex]p(x)=7x-2[/tex]

So your answer would be $72.3!

Simple interest is the amount of interest charged on a given principal at a given rate and for a given period of time.

The interest earned with an investment of $482 at a rate of 5.5% over 3 years is $79.53.

Simple interest is the amount of interest charged on a given principal at a given rate and for a given period of time.

We have,

P = Principal = $482

R = Rate = 5.5%

T = Time = 3 years

The formula for finding the simple interest is given:

SI = (P x R x T) / 100

The amount of interest from a $482 investment at 5.5% over 3 years:

= (482 x 5.5 x 3) / 100

= 7953 / 100

= 79.53

Thus,

The interest earned with an investment of $482 at a rate of 5.5% over 3 years is $79.53.

The total of Leiff’s online purchases will be $119.32.Option d is correct.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

If the video game's original price is $128 and the discount is 15%, then Leiff paid (100-15) = 85% of the original price for the item.

Consequently, the video game's price is as follows:

(0.85 x 128) = $108.80.

Leif must contribute an additional 5.3% of the new price, so

(100 + 5.3) = 105.3% of the new price

= (1.053 x 108.8) = $114.57

Including the video game's shipping cost,

114.57 + 4.75 = $119.32

Thus, the total price is $119.32

10 - 7 = 3

Therefore, 3 + 7 = 10

The length of the arc of the circle with a radius of 2 ft and the angle made at the centre equal to [tex]\dfrac{5\pi}{3}[/tex] is 10.5ft.

The length of the arc of a circle is equal to the product of the circumference of the circle and the ratio of the angle made by the arc of the circle to 2π. It is given by the formula,

[tex]\text{Length of the arc}= 2\pi r\times \dfrac{\theta}{2\pi}[/tex]

It is given that the radius of the circle is equal to 2 ft while the angle made by the arc at the centre of the circle is equal to [tex]\dfrac{5\pi}{3}[/tex]. And we know the formula for the length of the arc, therefore, the length of the arc,

[tex]\text{Length of the arc}= 2\pi r\times \dfrac{\theta}{2\pi}[/tex]

                            [tex]= 2\pi \times 2 \times \dfrac{\frac{5\pi}{3}}{2\pi}\\\\= 10.471 \approx 10.5\rm\ ft[/tex]

Hence, the length of the arc of the circle with a radius of 2 ft and the angle made at the centre equal to [tex]\dfrac{5\pi}{3}[/tex] is 10.5ft.

The equation given is y = -4.9x^2 + 19.8x + 58

It is of the form y = ax^2 + bx + c which is the standard form for quadratics.

We have,

Plug the first two values into the equation below

h = -b/(2a)

h = -19.8/(2*(-4.9))

h = 2.0204081632653

That value is approximate.

Rounding to the nearest whole number gets us roughly h = 2

Recall that (h,k) is the vertex of the parabola. In this case, it's the highest point. The cannonball reaches the highest point at roughly 2 seconds.

Answer:

[tex]686.6 cm^2[/tex]

Step-by-step explanation:

From the volume we can find the surface area of one of the triangle sides, by dividing it by its height. You find out that the surface of the triangle face is [tex]\frac {866}{20}=43.3 cm^2[/tex]. Let's pick two of them since we have two side faces (one close to us in the image, one far away), for a total area of [tex]86.6 cm^2[/tex]. At this point we need to add the area of the rectangular faces, which are three rectangles of length 20 and height 10, for a grand total of [tex]3\times10\times20 = 600 cm^2[/tex].

Adding everything together, we get [tex]600+86.6 = 686.6 cm^2[/tex]
