Answer: I believe that’s 96 squared cm

Step-by-step explanation:

The formula for surface area for a cube is 6 times the side to the power of 2

6*4^2 = 96 cm^2

Answer: 60% or 0.6

Step-by-step explanation:

A discount simply means the amount that is deducted from the normal cost of a good or service.

In the question above, the store was offering 40% as discount, this means that he'll only pay 60% of the price of the good. Note that (100% - 40% = 60%).

Therefore, the number that he should multiply the prices on the tags by to find the price he would have to pay will be 60% = 0.6.

Answer:

Your answer should be $29.40

Step-by-step explanation:

If you divide 21 by 5 you get 4.2, so each book costs $4.20.

4.2 x 7 = 29.4

Therefore, your total cost for 7 books will be $29.40

Explanation:

A diagram is optional, but I find it helps sometimes. The diagram is shown below.

Opposite the 10 degree angle is h. So we consider h the opposite side.

The hypotenuse is 12. The hypotenuse is always opposite the 90 degree angle.

Apply the sine ratio to solve for h

sin(angle) = opposite/hypotenuse

sin(10) = h/12

12*sin(10) = h

h = 12*sin(10)

h = 2.08377813200317 which is approximate

h = 2.1 miles is the plane's altitude which is also approximate

Side note: 2.1 miles is equal to 11,088 feet (multiply by 5280 to convert from miles to feet).

Answer:

A rectangle is bounded by the x-axis and the semicircle y = √(25 - x²). What length and width should the rectangle have so that its area is a maximum?

Step-by-step explanation:

Answer:

3x+20+(3x-20)=180(linear pair)

or,3x+20+3x-20=180

or6x=180

orx=180÷6

x=30

D=3x+20

=3×30+20

=90+20

=110

A=3x-20

=3×30-20

=90-20

=70

B=x+20

=30+20

=50

Answer:

Her mistake was in how many bags would be able to equally hold 4 bars.

325/4 is 81.25, which would mean there needs to be 82 bags, in which you wouldnt be able to hold 4 each equally.

A better option for Paz is to put 5 bars in each bag as 325 is an even multiple of 5. As such would result in the bag count being brought down to 65 bags to evenly hold all of the bars.

To find the volume of a rectangular prism, we multiply the length of the prism by the width of the prism by the height of the prism.

Answer:

i think 200

Step-by-step explanation:

Here , we are going to use Trigonometric ratios.

In given right angled ∆ ;

[tex]{:\implies \quad \sf \dfrac{x}{18}=\sin (60^{\circ}) \quad \bigg\{ \because \sin (\theta)=\dfrac{P}{H}\bigg\}}[/tex]

[tex]{:\implies \quad \sf x=\dfrac{18\sqrt{3}}{2} \quad \bigg\{\because \sin (60^{\circ})=\dfrac{\sqrt{3}}{2}\bigg\}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad x=9\sqrt{3} \: units}[/tex]

Also;

[tex]{:\implies \quad \sf \dfrac{y}{18}=\cos (60^{\circ}) \quad \bigg\{ \because \cos (\theta)=\dfrac{B}{H}\bigg\}}[/tex]

[tex]{:\implies \quad \sf x=\dfrac{18}{2} \quad \bigg\{\because \cos (60^{\circ})=\dfrac{1}{2}\bigg\}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad y=9 \: units}[/tex]

Hence , The required values for x and y are 9√3 and 9 units

Answer:

Breadth = 20 cm

Area = 800[tex]cm^{2}[/tex]

Step-by-step explanation:

Perimeter = 120 cm

length = 40 cm

Perimeter = 2 ( L + B )  

L - length     B - Breadth

120 = 2 ( 40 + B )

120 = 80 + 2B

2B = 120 - 80

2B = 40

B = [tex]\frac{40}{2}[/tex] = 20 cm

Breadth = 20 cm

Area of a reactangle = Length  × Breadth

= 40  × 20

= 800[tex]cm^{2}[/tex]

Answer:

He'll pay $110.25

Step-by-step explanation:

To find the area, we divide the shape into two parts at approximately the middle line. The top shape is a trapezoid of base length 7 feet and height 6 feet, while the bottom shape is a parallelogram with one side equal to 4 feet.

Area of trapezoid = (7 + 4)/2 x 6

Area of trapezoid = 33 sq ft

Area of parallelogram = 4 x 4

Area of parallelogram = 16 sq ft

Total area = 49 sq ft

Cost = 2.25 x 49

Cost = $110.25

what is the question?? nebebaiajbw

Answer:

Evaluate functions from their graph g(7)= 4

Step-by-step explanation:

If the point (a,b)(a,b)left parenthesis, a, comma, b, right parenthesis is on the graph, then g(a)=bg(a)=bg, left parenthesis, a, right parenthesis, equals, b.

We should look for the point on the graph whose x-coordinate is 7.

The point on the graph whose xxx-coordinate is 7 is the point (7,4)

Therefore, g(7)=4.

Answer:

4:30

Step-by-step explanation: if she arrives one fourth hour later its......

When Winona leaves her home at 4:15 and arrives at the theatre after one-fourth hour i.e. 15 minutes so the time when she arrived is 4:30.

Since at the time when Winona leaves her home at 4:15 and arrives at the theatre after 15 minutes

So, she arrived at the time

= 4: 15 +  15 minutes

= 4:30

Hence, When Winona leaves her home at 4:15 and arrives at the theatre after one-fourth hour i.e. 15 minutes so the time when she arrived is 4:30.
