Answer:

Each person can get 3 3/4 cookies.

Answer:

88 cm

Step-by-step explanation:

to find the circumference of a circle you can use the equation

d(pi)

d being diameter and pi in this case being 22/7

so you can directly multiply 28 and 22/7

28/1 * 22/7

you can cross cancel 28 and 7 making them 4 and 1 respectively

then you have 4/1 * 22/1

that is also 4 * 22

that is 88

Answer:

The answer is (-5,5).

Step-by-step explanation:

y = 10 - 3x

Substitute the options you get 5 for y which makes (-5,5) the answer.

10 × 47 = 470

(a) 470 – 326 = 144

453 – 144 = 309

309 The number of blue pens Uncle Ron had left was

309 + 471 = 780

(b)

780 ÷ 15 = 52

Thus , 52 blue pens were in each box.

Step-by-step explanation:

The number in question is equal to 2 times the temperature in degrees Celsius.

Since Alisha is working on a project about temperature conversion in her science class, and the formula for converting degrees Celsius to degrees Fahrenheit is F=C+32, to solve FC + 32 the following equation must be performed:

Therefore, the number in question is equal to 2 times the temperature in degrees Celsius.

Answer:

101.46

Step-by-step explanation:

Area= Lenght x With

Soo you would do 11.4 x 8.9 and get 101.46cm!

The area of the parallelogram with a height of 7.1 cm will be 80.94 square cm.

Let H be the height and W be the width of the parallelogram. Then the area of the parallelogram will be given as,

Area of the parallelogram = H × W square units

From the graph, the width of the base of the parallelogram is 11.4 cm. And the height of the parallelogram is 7.1 cm.

The area of the parallelogram is given as,

A = 11.4 x 7.1

A = 80.94 square cm

The area of the parallelogram with a height of 7.1 cm will be 80.94 square cm.

Answer:

162 cents

Step-by-step explanation:

to find the rate you want take the inches which is 21 and divide by the cost which is 63 and find the rate is 3 which means each inch costs 3 cents and so with that rate you can find the cost of 54 inchest of wire so you take your 54 inches and multiply it by 3 which is the cents per inch and find that 54 inches of wire would cost you 162 cents

Answer:

y=3x-7

Step-by-step explanation:

To find the equation of a perpendicular line, you first need to find the negative reciprocal of the slope given. The slope is -1/3, so the slope of the perpendicular line will be 3

Now we just need to find the y intercept using the point (3, 2) and you can plug the coordinates in and then solve for b. Let's see what that looks like.

y=3x+b

2=3*(3)+b

2=9+b

-7=b So now we know the y-intercept and slope. We just put them together now

y=3x-7

Answer:

Approximately 25.48

Step-by-step explanation:

V = πr²h

V=πr2h=π·1.32·4.8≈25.4846

V ≈ 25.48

Answer:

h = 4 cm

Step-by-step explanation:

The formula for volume of a cylinder is

V = πr²h      where V is the volume, r is the radius, and h is the height.

We are given V = 64π, and r = 4, plug those in and solve for h

64π = π(4²)h

64π = 16πh

(64π)/(16π) = (16πh)/(16π)      (divide both sides by 16π)

4 = (16π)/(16π)h

 4 = h

Here, we are provided a right circular cylinder with :

We know that :

[tex] \quad\hookrightarrow\quad{\pmb{ \mathfrak { Volume = \pi r^2 h }}}[/tex]

Therefore,

[tex] \implies\quad \sf{V = \pi r^2 h }[/tex]

[tex] \implies\quad \sf{64\pi = \pi r^2 \times 4 }[/tex]

[tex] \implies\quad \sf{ \pi r^2 \times 4 = 64\pi}[/tex]

[tex] \implies\quad \sf{r^2 =\dfrac{64\pi}{\pi \times 4} }[/tex]

[tex] \implies\quad \sf{ r^2 =\dfrac{\cancel{64}}{\cancel{4}}\times \cancel{\dfrac{\pi}{\pi}}}[/tex]

[tex] \implies\quad \sf{ r^2 = 16}[/tex]

[tex] \implies\quad \sf{r=\sqrt{16} }[/tex]

Answer:

The value of x from the figure is 58 degrees

To get the value of x, we will use the formula:

The angle at the vertex = 1/2(difference of angles at the arc)

Angle at the vertex = 1/2(160 - x)

51 = 1/2(160 - x)

102 = 160 - x

x = 160 - 102

x = 58 degrees

Hence the value of x from the figure is 58 degrees
