Answer:

18%

Step-by-step explanation:

0.12 is 12 percent.

We also have the 0.06 percent which would just be 6 percent

We need to add up those percentages to get 18 percent, for the people surveyed that cannot swim would be 18 percent.  

Our final answer is D.

The actual price is $46.73 lower than the expected price.

[tex]CPI_t=\frac{C_t}{C_0} * 100[/tex]

CPI=consumer price index in the current period

Ct= expected cost in current period

C₀ =cost in the base period

It is given that

Price in base period ie 1983 C₀= $78.75

The actual cost of the microwave oven = $92.66

Consumer Price Index= 177

So, expected price of microwave oven in the current period

Ct= CPIt * C₀ /100 = 177*78.75/100 = $139.39

Difference between the actual price and expected price = 139.39-92.66=$46.73

Therefore, The actual price is $46.73 lower than the expected price.

Answer:

23.09 ft

Step-by-step explanation:

Here we are given that the angle from stake in ground to the top of the tree is 60° and the height of the tree is 40ft . We are interested in finding out the distance from stake to the bottom of the tree . For figure refer to the attachment .

From the figure , BC = 40ft which is the perpendicular of the right angled triangle ABC . Also assume that AB = x ft , which is the base of the triangle .

Now since we have base and perpendicular , we should use the ratio of tangent as ,

[tex]\rm\longrightarrow tan\theta =\dfrac{perpendicular}{base}=\dfrac{p}{b} [/tex]

And here [tex]\theta[/tex] = 60° . On substituting the respective values , we have ;

[tex]\rm\longrightarrow tan 60^o =\dfrac{40\ ft}{x \ }\\ [/tex]

And the value of tan60° = √3 , so that ;

[tex]\rm\longrightarrow \sqrt3 =\dfrac{40\ ft}{x} [/tex]

Cross multiply ,

[tex]\rm\longrightarrow x =\dfrac{40}{\sqrt3}ft. [/tex]

The value of √3 is 1.732 approximately .

[tex]\rm\longrightarrow x =\dfrac{40}{1.732}ft. [/tex]

Simplify,

[tex]\rm\longrightarrow \underline{\underline{\red{{x =23.09\ ft }}}} [/tex]

And we are done !

x² - 100 is the difference of two squares.

The factorization of the difference of two squares is

a² - b² = (a + b)(a - b)

x² - 100 = (x + 10)(x - 10)

Hi! I hope you're enjoying your day!

I can help Maritza solve this maths problem. ;)

The first step in solving this problem is using the Distributive Property and distribute 5.

How to distribute 5:

multiply 5 times 4m and -6 and simplify :)

So let's do it! :)

5(4m-6)-10

20m-20-10

Now, combine like terms:

[tex]\boxed{\boxed{\bold{20m-30}}}[/tex]

And yeah, we can't simplify this expression, because 20m and -30 are not like terms.

Hope everything is clear.

If you have any questions, please comment.

Hello there! Your question is missing some important information to solve.  I will solve the equation by simplifying the expression. =)

Answer:

[tex]20m-40[/tex]

Step-by-step explanation:

Given the expression:

[tex]5(4m-6)-10[/tex]

You can simplify it as follows:

1. Apply the Distributive Property multiplying each term inside the parentheses by the number 5 outside:

[tex]=(5)~(4m)-(5)~(6)-10[/tex]

[tex]=20m-30-10[/tex]

2. Add the like terms (remember that like terms have the same variables with the same exponents):

[tex]=20m-40[/tex]

Hence, the answer is [tex]20m-40[/tex]

Knowing the angles are equal, the value for y is 40.

The angle bisector is the line segment that divides the angle into two equal angles.

Thus, if OF is the angle bisector for EOG, the angles EOF and FOG are equal.

For finding y, you can write:

EOG=FOG

y+30=3y-50

y-3y=-50-30

-2y=-80

y=80/2

y=40

Answer:

A) complementary angles

B) 58 degrees

Step-by-step explanation:

A) ∠DOE and ∠EOB are complementary angles since they both add up to 90 degrees (or right angle).

B) x + 32 = 90 (Complementary angles)

Subtract 32 to both sides

x = 90 - 32

x = 58 degrees.

Answer:

cos2t/cos²t

Step-by-step explanation:

Here the given trigonometric expression to us is ,

[tex]\longrightarrow \dfrac{cos^4t - sin^4t }{cos^2t } [/tex]

We can write the numerator as ,

[tex]\longrightarrow \dfrac{ (cos^2t)^2-(sin^2t)^2}{cos^2t } [/tex]

Recall the identity ,

[tex]\longrightarrow (a-b)(a+b)=a^2-b^2[/tex]

Using this we have ,

[tex]\longrightarrow \dfrac{(cos^2t + sin^2t)(cos^2t-sin^2t)}{cos^2t}[/tex]

Again , as we know that ,

[tex]\longrightarrow sin^2\phi + cos^2\phi = 1 [/tex]

Therefore we can rewrite it as ,

[tex]\longrightarrow \dfrac{1(cos^2t - sin^2t)}{cos^2t}[/tex]

Again using the first identity mentioned above ,

[tex]\longrightarrow \underline{\underline{\dfrac{(cost + sint )(cost - sint)}{cos^2t}}}[/tex]

Or else we can also write it using ,

[tex]\longrightarrow cos2\phi = cos^2\phi - sin^2\phi [/tex]

Therefore ,

[tex]\longrightarrow \underline{\underline{\dfrac{cos2t}{cos^2t}}}[/tex]

And we are done !

[tex]\rule{200}{4}[/tex]

Additional info :-

Derivation of cos²x - sin²x = cos2x :-

We can rewrite cos 2x as ,

[tex]\longrightarrow cos(x + x ) [/tex]

As we know that ,

[tex]\longrightarrow cos(y + z )= cosy.cosz - siny.sinz [/tex]

So that ,

[tex]\longrightarrow cos(x+x) = cos(x).cos(x) - sin(x)sin(x) [/tex]

On simplifying,

[tex]\longrightarrow cos(x+x) = cos^2x - sin^2x [/tex]

Hence,
