Answer:

Answer is100*5/8 = 62.5

Answer:

62.5

Step-by-step explanation:

100×5/8=125÷2=62.5

Answer:

5/8 x 4/9 = 20/72 as simplified as 5/18 in fraction form. 5/8 x 4/9 = 0.2778 in decimal form.

Step-by-step explanation:

The product of -4/9 and -5/8 is 5/18.

Given are two negative fractions -4/9 and -5/8, we need to find their product,

To find the product of two negative fractions, you can multiply their numerators together and their denominators together, while keeping the negative sign.

Let's find the product of -4/9 and -5/8:

Product = (-4/9) x (-5/8)

To calculate the product, multiply the numerators and denominators:

Product = (-4 x -5) / (9 x 8)

Simplifying the multiplication:

Product = 20 / 72

Now, you can simplify the fraction by finding the greatest common divisor (GCD) of the numerator and denominator, which in this case is 4:

Product = (20/4) / (72/4)

= 5/18

Therefore, the product of -4/9 and -5/8 is 5/18.

Step-by-step explanation:

Answer:

I just learned this about a few weeks ago I hope this helps.

Step-by-step explanation:

Since it's cosine you're only looking at Adjacent and the hypotenuse which the adj is 20 and the hyp is 25 so since cosine is adj/hyp you do 20/25 then simplify it to 20/25 divide both by 5 so it's simplified to 4/5.

Then you do Cos-1(4/5)=36.869 which is rounded to the tenth 36.9 but rounded to the hundredth 36.87.

Answer:

Options C and D

Step-by-step explanation:

From the graph attached,

Coordinates of the vertices,

X → (0, 0)

Y → (-1, -2)

Z → (0, -2)

Rule for the rotation of a  point (h, k) by 180° about the origin is given by,

(h, k) → (-h, -k)

By this rule,

Coordinates of the image points will be,

X(0, 0) → X'(0, 0)

Y(-1, -2) → Y'(1, 2)

Z(0, -2) → Z'(0, 2)

Therefore, Option (C) and Option (D) are the correct options.

The second statement.

Step-by-step explanation:

Any increasing exponential function will always eventually be greater than any other non-exponential function.

The statement that is true from the function given above is:
"Over the interval [-2, 2], function f is increasing at a faster rate than function g is decreasing." (Option D)

A function in mathematics is known as an expression of a relationship involving two variables:

It is clear from the number array (attached) that x > 0, f(x) ↑ while x<  0 f(x) ↓.

While for g(x) it is confirmed that 0 <x<2, gx) ↓.

[-2< x< 0, g(x) may ↓ or ↑]

Hence, x from 0 to 2, g(x) from 6 to -16, that has been modified for 22 while the f(x) changes from 0 to 26, and changed from 26,  26 > 22.2

Answer:

y = [tex]\frac{4}{5}[/tex] x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{4}{5}[/tex] , then

y = [tex]\frac{4}{5}[/tex] x + c ← is the partial equation

To find c substitute (- 5, 2 ) into the partial equation

2 = - 4 + c ⇒ c = 2 + 4 = 6

y = [tex]\frac{4}{5}[/tex] x + 6 ← equation of line

Answer:

Below.

Step-by-step explanation:

Use the point-slope form of a straight line.

y - y1 = m(x - x1)

Here m = 4/5, x1 = -5 and y1 = 2, so

y - 2 = 4/5(x - -5))

y - 2 = 4/5 x  + 4

y = 4/5x + 6 is the answer in slope-intercept form.

Standard form:

Multiply through by 5:

5y = 4x + 30

4x - 5y = -30 is the answer in standard form.

Answer: V ≈ 46.6

The formula for a cylinder with a diameter is: [tex]V=\pi (\frac{d}{2})^2h[/tex]

As that being said, we multiply the diameter with pi, then divide the diameter by 2, then multiply the height.

Remember, pi is 3.14.

π → 3.14

Let's break the equation down.

3.14 × 2.4 / 2 × 10.3.

Let's solve.

3.14 × 2.4 / 2 × 10.3 = 46.5961

We solved the equation, but we aren't done. We round the decimal to the nearest tenth.

To do that, find the 5 in the tenth place and take a look at 9. Round up if the digit to the right is greater or equal to 5. Round down if the digit to the right if less than 5.

Therefore, 9 is greater than 5, so we round up.

46.5961 → 46.6

Hence, 46.6 is the answer.

Answer:

v=46.6

Step-by-step explanation:

ok so the shape of the bottle isn't given, but we can assume that it's a cylinder.

with that, we need to 'find' the formula for the volume of a cylinder-

v=πr²h

now, lets plug in what we know-

we were given the diameter, which is the straight line passing from side to side through the center of a body or figure, especially a circle or sphere. but what we need is the radius, so to find that we'll divide the diameter in half-

2.4/2=1.2

now we can plug in the radius and height-

v=π*1.2²*10.3

v=46.6

good luck :)

Given:

The figure of a right triangle.

To find:

The value of x.

Solution:

In a right angle triangle,

[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]

In the given right triangle,

Hypotenuse = 15

Perpendicular = 12.5

Now,

[tex]\sin x^\circ=\dfrac{12.5}{15}[/tex]

[tex]\sin x^\circ=0.83333[/tex]

[tex]x^\circ=\sin^{-1}0.83333[/tex]

[tex]x^\circ =56.442345^\circ[/tex]

[tex]x\approx 56[/tex]

Therefore, the equation used to find x is [tex]\sin x^\circ=\dfrac{12.5}{15}[/tex] and the value of x is 56.

Given:

The graph of two function f(x) and g(x).

The expression is:

[tex]-1\cdot f(-8)-4\cdot g(4)[/tex]

To find:

The value of the given expression.

Solution:

From the given graph, it is clear that

[tex]f(-8)=-5[/tex]

[tex]g(4)=3[/tex]

Substitution [tex]f(-8)=-5[/tex] and [tex]g(4)=3[/tex] in the given expression, we get

[tex]-1\cdot (-5)-4\cdot 3[/tex]

[tex]=5-12[/tex]

[tex]=-7[/tex]

Therefore, the value of the given expression is -7.

Answer:

27.7m

Step-by-step explanation:

Step 1

We find the Circumference of the nylon thread.

The formula = 2πr

The diameter of the thread = 0.88m

Radius = Diameter/2

= 0.88m/2

= 0.44m

Circumference = 2 × π × 0.44m

= 2.7646015352m

Approximately = 2.765m

Step 2

We calculate the distance

Number of revolutions = 10

Therefore, the Distance or how far the metal weight can travel =

Circumference of the wheel × Number of revolutions

= 2.765m × 10

= 27.65m

Approximately to 1 decimal place = 27.7m

Answer:

x=-5 or -5

Step-by-step explanation:

x - 4 = 2x + 1

Subtract x from both sides canceling out the x on the left, getting...

-4 = x + 1

Then subtract the 1 from both sides canceling out the 1 on the right, getting...

-5 = x

Subtracting x from 2x gets you 1x which you just write as x because there is only one x. Doing the equation from the other side will still get you the same answer and I will show you.

x - 4 = 2x + 1

-x - 4 = 1

-x = 5

x = -5
