Answer:

huh?

Step-by-step explanation:

Answer:

You can tell if two fractions are proportional by using cross multiplication. Only equivalent fractions are proportional. To do this, multiply the denominator, the bottom number in the fraction, of the first fraction with the numerator, the top number in the fraction.

Answer:

Equilateral

Step-by-step explanation:

All angles are the same, so the sides are the same as well

Classifications:

Scalene = no sides and angles are the same to others

Equilateral = All sides and angles are congruent

Isosceles = 2 sides and 2 angles are congruent.

Step-by-step explanation:

50.27 should be the area of a circle that has a radius of 4 in.

Answer:

147.7 m²

Step-by-step explanation:

Area of the triangular faces = 1/2 × base × height

A triangular pyramid has lateral faces with bases of 8 meters and heights of 10 meters.

Hence: 1/2 × 8 × 10 = 40 m²

A triangle has 3 faces, hence, area of the 3 faces = 3 × 40 m²

= 120m²

The area of the base of the pyramid is 27.7 square meters.

Hence, the surface area of the pyramid is calculated as:

Area of the 3 lateral faces of the pyramid + Base area

= 120m² + 27.7 m²

= 147.7 m²

The surface area of the pyramid is 147.7 square meters.

Answer:

34

Step-by-step explanation:

We solve the above question using Triangle Proportionality Theorem

This states that:

TU : TS = QR : RS

TU/TS = QR/RS

TU = ?

TS= 17

RS = 13

QR = 26

Hence,

TU/7 = 26/13

Cross Multiply

13 × TU = 17 × 26

TU = 17 × 26/13

TU = 17 × 2

TU = 34

Therefore, TU = 14

B.) 140 is your answer for your problem

Answer:

56 rabbits

Step-by-step explanation:

Given that  t represents the time, and weeks, and P(t) is the population of the rabbits and that the population doubles every 6 weeks.

In 126 days, there are

= 126/7

= 18 weeks

It means that the rabbit population will double

= 18/6 times

= 3 times

Since there are currently 7 rabbits at the end of 6 week,

P(6) = 7 * 2

= 14

At the end of 12 weeks

P(12) = 14 * 2 = 28

At the end of 18 weeks

P(18) = 28 * 2 = 56

Hence there will be 56 rabbits at the end of 126 days

Answer:

40 gallons of premium antifreeze and 100 gallons of water should be used to obtain 140 gallons of a mixture that contains 20% pure antifreeze.

Step-by-step explanation:

Since a chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture, and the premium antifreeze solution contains 70% pure antifreeze, and the company wants to obtain 140 gallons of a mixture that contains 20% pure antifreeze, to To determine how many gallons of water and how many gallons of the premium antifreeze solution must be mixed, the following calculation must be performed:

50 x 0.7 + 50 x 0 = 35

40 x 0.7 + 60 x 0 = 28

30 x 0.7 + 70 x 0 = 21

29 x 0.7 + 71 x 0 = 20.3

28.57 x 0.7 + 71.43 x 0 = 20

140 x 0.2857 = 40

Therefore, 40 gallons of premium antifreeze and 100 gallons of water should be used to obtain 140 gallons of a mixture that contains 20% pure antifreeze.

A slightly more accurate value is 38.28 cm^2, when using pi = 3.14

=================================================

Explanation:

The vertical height of the rectangle is 4 cm, which forms the diameter of the semicircle. The diameter cuts in half to 4/2 = 2, which is the radius.

The area of a full circle with radius r = 2 cm is approximately pi*r^2 = 3.14*2^2 = 12.56 square cm.

Cut that in half to get (12.56)/2 = 6.28 square cm. This is the approximate area of the semicircle.

--------

The area of the rectangle is length*width = 6*4 = 24 square cm.

The triangle has its bottom portion of 4 cm (because 10-6 = 4) and its height is 4 cm, so we get the triangle area of base*height/2 = 4*4/2 = 8 square cm.

The last thing we do is add up all the results we got:

6.28 + 24 + 8 = 38.28

That rounds to 38 square cm when rounding to the nearest whole number.

Answer:

x=6 degrees

Step-by-step explanation:

I know that 31+(10x-1)=90. Then I have to subtract 31 from 90 to get 10x -1.

That's 59. I solve for x in the equation 59=10x-1.

That is the same thing as 60=10x, which is also the same as 6=x.

(1,0) and (3,0)

Step-by-step explanation:

The roots are always shown where the parabola crosses the x-axis.

In this particular graph, the parabola crosses at (1, 0) and (3, 0). Which means the roots are:

x = 1 and x = 3

Step-by-step explanation:

This is saying " Every number possible thats less than, but not 0" so you show that

Step-by-step explanation:

the height of the triangle = √(5×15)= √75

=5√3 units

the base of triangle= 20 units

so, the area = ½×20×5√3= 50√3 units

or 86.60 units
