Answer:

Step-by-step explanation:

Given that the original price of the TV is $499, the new price after the given percent of change of 10% would be, $548.9. 10% of $499 is $49.9. This is added to the original price. Now, if the increase is 30%, 30% of $499 would be $149.7. Add this to $499 and the new price is $648.7. Hope this answers your question.

Answer:$427.14

Step-by-step explanation:

Multiply $499 and 20% = 99.8

499-99.8=399.2

399.2 multiplied by 7%=27.944

Add 399.2 and 27.944= 427.144

Find the value of z. round to the nearest hundredth
Svetradugi [14.3K]

ANSWER

C. 64.29

EXPLANATION

The bigger right triangle is similar to the smaller right triangle, therefore

\frac{30}{14}  =  \frac{z}{30}

Multiply both sides by 30;

30 \times  \frac{30}{14}  =  \frac{z}{30}  \times 30

Simplify

z =  \frac{900}{14}

z = 64.28571429

We correct to the nearest hundredthth to obtain,

z = 64.29

The correct choice is C.

The area of a rectangular flower bed is 24 square feet. The perimeter of the same flower bed is 22 feet. What are the dimensions
Vesna [10]

Answer:

3 ft by 8 ft

Step-by-step explanation:

We were given the area as 24 square feet which means that

L×w= 24....eqn(1)

We were given the perimeter as 22 square feet which means that

22= 2(L +w).......eqn(2)

If we divide both cause by 2 in eqn(2) we have

11= L+ w .....eqn(3)

W= 11-L.........eqn(4)

Substitute eqn(4 into eqn(1)

L× (11-L)=24

-L^2 +11L-24=0

If we factorize

(L-8)(L-3)

L=3 or 8

From eqn4)

W=11-L

At L=3

W=11-3=8

Hence, the dimension is 3 ft by 8 ft

Triangle ABC and DEF are right triangles, as shown. Triangle ABC is similar to triangle DEF. which ratios are equal to sin C?
Dafna11 [192]

Answer:

First option and Fourth option.

Step-by-step explanation:

To solve this exercise you need to use the following Trigonometric Identity:

sin\alpha=\frac{opposite}{hypotenuse}

In this case you know that:

\alpha =C

Since triangle ABC is similar to triangle DEF:

\angle C=\angle F

Let's begin with the triangle ABC.

You can identify that:

opposite=AB\\hypotenuse=AC

Then, substituing values, you get:

sinC=\frac{AB}{AC}

In triangle DEF, you know that:

opposite=DE\\hypotenuse=DF

So, substituing values, you get:

sinF=sinC=\frac{DE}{DF}

Suppose that all the points on the circular dartboard shown are equally likely to be hit by a dart. if the radius of the red cir
Anestetic [448]
This equals the  the area of white part / area of the entire dartboard

area of the entire board = pi * 6^2 = 36pi

area of white part = 36pi  - 2^2*pi  = 32pi

do required probability = 32pi / 36pi  =  0.889   or 88.9 %   (to nearest tenth)


or as a fraction it is 8/9
