Answer:

the answer is (25-π) there was no figure drawn

Answer:

equation: 55 + (2x + 3) + 90 = 180

55 + 2x + 3 + 90 = 180

2x + 148 = 180

2x = 32

x = 16

Answer:

55 + 50 + 2x+3 + 2x+8 = 180

x = 16

Step-by-step explanation:

55 + 50 + 2x+3 + 2x+8 = 180

113 + 4x = 180

4x = 64

x = 16

answer

what is the interest rate??????

Answer:

a) 94.2 cm

b) 78.5%

Step-by-step explanation:

a) since the square side = 30 cm

it means the diameter = 30 cm

then circumference of the largest circle that can be cut = 3.14×30 = 94.2 cm

b) the perimeter of the square = 30×4 = 120

94.2 for 120

x% for 100%

x = (100×94.2)/120 = 9420/120 = 942/12 = 78.5%

Answer:

x < 7

Step-by-step explanation:

0.5 + 2x < 14.5

2x < 14.5 - 0.5

2x < 14

x < 14 ÷ 2

x < 7

( To solve this is basically solving an equation. It's just that that instead of an equal sign, a greater than, less than, greater than or equal to or a less than or equal to sign is present. )

Answer:

6³ because 2³ and 3³ can be multiplied because they are to the same power, and keep the same power. Also, 6³ is 216.

Hope this helps!

Answer:

We have to use the formule to calculate the vertex which is: V(-b/2a;4ac-b^2/4a)

A) y=x+7 where a=1 b=0 and c=7

By replacing we have: V(0;28/4) V(0;7)

B) y=-x where a=-1 b and c=0 so V(0,0)

Answer:

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.

Answer: In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

Answer:

4

Step-by-step explanation:

You set f(x) = 9 and solve from there.

9 = 4x - 7

+7         +7

16 = 4x

/4     /4

x = 4

Answer:

The answer is 4

Step-by-step explanation:

f(x)=4x-7

f(x)=9

9=4x-7

9+7=4x-7+7

(the -7 and the +7 cancel out, and remember: whatever you do the one side you have to do to the other)

16=4x

(divide by 4 to isolate x and do the same to the other side of the equation so you get the answer)

so, x=4

Answer: 60%

Answer:

The slope of the line that intersects the points (13, -4) and (1, 12) is 4/-3.

Step-by-step explanation:

The equation [tex]m=\frac{y2-x2}{y1-x1}[/tex] is used to solve for slope [tex]m[/tex].

[tex]m=\frac{12-(-4)}{1-13}=\frac{12+4}{-12} =\frac{16}{-12} =\frac{4}{-3}[/tex]

If you need it in decimal form, then 4/-3=-1.33333333333

Answer:

7.2

Step-by-step explanation:

to find the diameter you always times it by 2

whilst to find the radius you do diameter ÷ 2

so if you times 3.6 x 2 = 7.2

also, you can't round 7.2 to the nearest tenth because it's already in that form

Answer:

Step-by-step explanation:

a radius is the length of a line segment from the center of a circle to the edge of the circle

a diameter is the length of a line segment from both edges of a circle and passing through the center of a circle

the line segment in the diagram looks like a radius (assuming the black dot represents the center of the circle)

if you left the line segment where it is and then rotate another the line segment in the diagram around so that is straight in line with the original line segment you would see that you just created a diameter

the diameter is twice as long as one radius

a diameter = 2 times a radius         d = 2r        d = diameter  r = radius

so d = 2 x 3.6           use your own calculator to solve

Answer:

-0.82 is closest to -1, and -0.28 is closest to -1/4

Step-by-step explanation:

you can start by converting all of them to a fraction or decimal:

-0.28 = -28/100 = -7/25 = -14/50

-0.82 = -82/100 = -41/50

-1/5 = -10/50

-4/5 = -40/50

-1 = -50/50

-1/4 = -12.5/50

Answer:

14 son varones

Step-by-step explanation:

Primero tenemos que sumar la cantidad de niños y niñas para saber cuantos hay en total

45 + 35 = 80

60 de ellos viven en el Distrito de Breña entonces los descontamos del total

80 - 60 = 20

Esto nos dice que 20 NO viven en Breña. Si 30% son mujeres quiere decir que el resto 70% son varones. Asi que multiplicamos los 20 por 70% en formato decimal que seria 0.70

20 * 0.70 = 14

Finalmente, podemos ver que 14 son varones viviendo fuera de Breña

Answer:

A

Step-by-step explanation:

Given the 2 equations

y = 3x + 3 → (1)

y = - 2x + 3 → (2)

Substitute y = 3x + 3 into (2)

3x + 3 = - 2x + 3 ( add 2x to both sides )

5x + 3 = 3 ( subtract 3 from both sides )

5x = 0 , then

x = 0

Substitute x = 0 into (1)

y = 3(0) + 3 = 0 + 3 = 3

solution is (0, 3 ) → A

Answer:

  arc MKL ≈ 19.02 m

Step-by-step explanation:

The figure shows angle KNL is the complement of angle KNJ, so is ...

  ∠KNL = 90° =∠KNJ

  ∠KNL = 90° -52° = 38°

We know that KM is a diameter, so arc MJK = 180°, and ...

  arc MKL = 180° +38° = 218°

In radians, that angle measure is ...

  218° × π/180° rad = 109π/90 rad

An arc length is given by the formula ...

  s = rθ . . . . . where r is the radius and θ is the radian measure of the arc

For this problem, the radius is MN = 1/2MK = 5 m, and the length of arc MKL is ...

  s = rθ

  arc MKL = (5 m)(109π/90) = 109π/18 m

  arc MKL ≈ 19.02 m

Answer:

Max height = 128feet

Time = 0secs

Step-by-step explanation:

Given the height in ft of a rocket after x seconds is given by y=128-16x^2, at maximum height, the velocity of the object is zero that is;

dy/dx = 0

0 - 32x = 0

x = 0/-32

x = 0

Hence the time taken for the object to reach its maximum height is 0 secs

To get the maximum height reached, you will substitute x = 0 into th expression given as shown;

y = 128 - 16x^2

y = 128 - 16(0)^2

y = 128 - 0

y = 128feet

Hence the maximum height reached by the rocket is 128feet
