Which of the following expressions is equivalent to
8(2x + 7)?
(1) 10x+15
(3) 16x+7
(2) 10x+7
(4) 16x +56

Answer:

As a fraction it's ¼, as a decimal it's 0.25 and as a percentage it's 25%

Answer:

= 1/5

.2

20%

Step-by-step explanation:

In the bag there are 5 pennies, 4 nickels , 5 dimes, 2 quarters

We add 1 penny 2 dimes and 1 quarter

Now in the bag

6 pennies, 4 nickels, 7 dimes, 3 quarters

for a total of 20 coins

P ( nickel) = number of nickels / total

                 = 4/20 = 1/5

                  .2

                   20%

She is more likely to draw a nickel before the 1 penny 2 dimes and 1 quarter because there are fewer coins in the bag that are not nickels

Answer:

Number of drummers in original ensemble  [tex]=3[/tex]

Number of flutists in original ensemble [tex]=21[/tex]

Step-by-step explanation:

The ratio of flutists to drummers is [tex]7:1[/tex]

Let number of flutists and drummers be [tex]7x[/tex] and [tex]x[/tex].

As 2 drummers join the group and 6 flutists quit,

Number of drummers = [tex]x+2[/tex]

Number of flutists = [tex]7x-6[/tex]

New ratio of flutists to drummers = [tex]3:1[/tex]

So,

[tex]\frac{7x-6}{x+2}=\frac{3}{1}\\ 7x-6=3(x+2)\\7x-6=3x+6\\7x-3x=6+6\\4x=12\\x=3[/tex]

So,

Number of drummers in original ensemble  [tex]=x=3[/tex]

Number of flutists in original ensemble [tex]=7x=7(3)=21[/tex]

Answer:

0.48

Step-by-step explanation:

Just move back one decimal point of 4.8

Answer: I just did this one lol

Step-by-step explanation:

10 percent *4.8 =

(10:100)*4.8 =

(10*4.8):100 =

48:100 = 0.48

Now we have: 10 percent of 4.8 = 0.48

Question: What is 10 percent of 4.8?

Percentage solution with steps:

Step 1: Our output value is 4.8.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$4.8=100\%$.

Step 4: Similarly, $x=10\%$.

Step 5: This results in a pair of simple equations:

$4.8=100\%(1)$.

$x=10\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{4.8}{x}=\frac{100\%}{10\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{4.8}=\frac{10}{100}$

$ x=0.48$

Answer:

x intercept is -5

y intercept is 4

Answer:

Step-by-step explanation:

-4x +  5y = 20

Divide the equation by 20

[tex]\frac{-4x}{20}+\frac{5y}{20} = \frac{20}{20}\\\\\\\frac{x}{-5}+\frac{y}{4}=1\\\\[/tex]

x intercept =  (-5)

y intercept = 4

Sum of all angles in a triangle = 180°

Which means :-

∠1 + ∠2 + ∠3 = 180°

[tex]2x + x + x + 8 = 180°[/tex]

[tex]4x + 8 = 180°[/tex]

[tex]4x = 180 - 8[/tex]

[tex]4x = 172[/tex]

[tex]x = \frac{172}{4} [/tex]

[tex]x = 43[/tex]

Angle 1 :-

= 2x

= 2 × 43

Angle 2 :-

= x

Angle 3 :-

= x + 8

= 43 + 8

[tex]therefore \: , \: the \: value \: of \: x = 43°[/tex]

Answer:the domain is all real numbers it also like the x value and the range is all y value

Step-by-step explanation:

Answer:

The domain is the set of values of "x" for which the function has meaning.

Based on my knowledge x can be any real number except for zero.

The range of f(x) is the same as finding all that y could be.

The range of f(x) is all the y values where there is a number x with y = f(x).

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

cosec x = [tex]\frac{1}{sinx}[/tex] , cot x = [tex]\frac{cosx}{sinx}[/tex]

Consider the left side

[tex]\frac{(1+cosA)^2-(1-cosA)^2}{sin^2A}[/tex] ← expand and simplify numerator

= [tex]\frac{1+2cosA+cos^2A-(1-2cosA+cos^2A}{sin^2A}[/tex]

= [tex]\frac{1+2cosA+cos^2A-1+2cosA-cos^2A}{sin^2A}[/tex]

= [tex]\frac{4cosA}{sin^2A}[/tex]

= 4 × [tex]\frac{1}{sinA}[/tex] × [tex]\frac{cosA}{sinA}[/tex]

= 4cosecAcotA

= right side,  thus proven

Answer:

its 3.05

Step-by-step explanation:

The coordinates of A will be at (-10, -5) when the transformation (x,y) → (x + 10, y + 5) is  performed on point A.

Given the coordinate of the resulting image after the transformation is A'(0, 0). We need to get the coordinate of the original image A.

Since the transformation (x,y) → (x + 10, y + 5) is performed on A.

A = (0 - 10, 0 - 5)

If we are going from the pre-image to the image, we will translate to the left and downwards

A = (-10, -5)

Hence the coordinates of A will be at (-10, -5)

Answer:

y=x+4

Step-by-step explanation:

Slope is positive and it goes up by 1 so it is just 1 and the y-intercept is 4 so it is y=x+4
