Answer:

.52

Step-by-step explanation:

We can write an equation

supports/all

we can see that 27 males and 25 females support which means that

27+25= 52 total people support

now we just need to find the number of people surveyed

we do this by summing everything

27+25+18+13+5+12=100

52/100 = .52

Answer:

.52

Step-by-step explanation:

Add both male and female supports to get 52

then add all the numbers to get a total of 100

52/100=.52

Answer:

0.7

Step-by-step explanation:

Use the parameter (x) to express the unknown quantity. Now express the given information as an equation.

[tex]\frac{1}{4}(2x+7)=3x[/tex]

Inverse operations,

[tex]2x+7=12x[/tex]

[tex]7=10x[/tex]

[tex]x=0.7[/tex]

Answer:

36m^2

Step-by-step explanation:

3*2+ 3*4/2 *2 + 4*2 + 5*2

= 6+12+8+10

= 36

Answer:

x = 5

Step-by-step explanation:

14x + 22x = 180

36x = 180

x = 5

Answer:

[tex]\huge\boxed{⎆Answer\hookrightarrow}[/tex]

The 2 angles in the given picture form supplementary angles. So, together they'll add up to 180°.

[tex]14x + 22x = 180 \\ 36x = 180 \\ x = \frac{180}{36} \\ x = 5[/tex]

⇻ The value of X is 5.

Step-by-step explanation:

total is 50 so 20*2 is 40%

Answer:

the Pythagorean theorem states:  a^2 + b^2 = c^2  

1) in this case a=18 and b1=25

18^2 + 25^2 = c1^2  

324 + 625 = c1^2

949 = c1^2

√949 = c1

cca. 30.8 = c1

2) in this case a=18 and b' = b2 - b1 = 40 - 25 = 15

in the picture im attaching i highlighted the triangles we are working with, and there you can clearly see that b' (the horizontal line at the bottom of the red tr.) is the difference between the lines b2 and b1

now you can use the same technique as in the first case, and the final answer will be cca. 23.4 = c2

3) in this case a=18 and b'' = b4 - b3 = 75 - 55 = 20

same thing as number 2, final answer cca. 26.9 = c3

Answer: 4.2

Step-by-step explanation:

Here's the formula for how to find the hypotenuse: (a and b are the two legs for the triangle-- it doesn't matter which leg is a and which leg is b, but c MUST be the hypotenuse)

[tex]a^2+b^2=c^2[/tex]

[tex]1.9^2+3.8^2=c^2[/tex]

[tex]3.61+14.44=c^2[/tex]

[tex]18.05=c^2[/tex]

[tex]\sqrt{18.05} =c[/tex]

[tex]c=4.2[/tex]

Answer:

[tex]\angle 1 = 99^\circ[/tex]

[tex]\angle 3 = 99^\circ[/tex]

[tex]\angle 4 = 81^\circ[/tex]

Step-by-step explanation:

Given

[tex]\angle 2 = 81^\circ[/tex]

Required

Determine: [tex]\angle 1 . \angle 3 , \angle 4[/tex]

Solving for [tex]\angle 1[/tex], we have:

[tex]\angle 2 + \angle 1 = 180^\circ[/tex] --- angle on a straight line

So, we have:

[tex]\angle 1 = 180^\circ-\angle 2[/tex]

[tex]\angle 1 = 180^\circ-81^\circ[/tex]

[tex]\angle 1 = 99^\circ[/tex]

To solve for [tex]\angle 3, \angle 4[/tex], we have:

[tex]\angle 3 = \angle 1[/tex]

[tex]\angle 4 = \angle 2[/tex] --- Vertically opposite angles

So:

[tex]\angle 4 = 81^\circ[/tex]

[tex]\angle 3 = 99^\circ[/tex]

Answer:

3a/6b

Step-by-step explanation:

-5a/18b cannot be simplified. Therefore, 3a/6b and -5a/18b are not the same.

3a/6b can be simplified. Both the denominator and the numerator can be divided by 2. Therefore, the fraction will be a/2b. a/2b is equal to a/2b so 3a/6b is the correct answer.

Since the cost of Twitch is $25 no matter what, that will be our y-intercept (essentially when no other subscriptions are bought). Since with every purchase x we make, we spend an additional $5, the slope of the line (x coefficient) will be 5.

Answer:

Step-by-step explanation:

a^2+b^2=c^2

Answer:

a. Sin B = 15/17

b. Cos B = 8/17

c. Tan B = 15/8

Step-by-step explanation:

Recall: SOHCAHTOA

Reference angle = B

Opp = 15

Adjacent = 8

Hypotenuse = 17

a. Sin B = Opp/Hyp (applying SOH)

Substitute

Sin B = 15/17

b. Cos B = Adj/Hyp

Substitute

Cos B = 8/17

c. Tan B = Opp/Adj

Substitute

Tan B = 15/8

Answer:

A

Step-by-step explanation:

-3<-2

Answer:

9) a = 8, b = 4√2

10) x = 7√2, y = 7

11) x = 5√2, y = 5

12) a = 10, b = 5√2

Step-by-step explanation:

You can notice all these triangles are special as 45° - 45° - 90° triangles. In 45° - 45° - 90° triangles, the hypotenuse is √2 times the sides. We can set up these equations and solve:

9)

a = 4√2 * √2

a = 8

Since the triangle is isosceles, the legs are the same length, so:

b = 4√2

10)

x = 7 * √2

x = 7√2

Since the triangle is isosceles, the legs are the same length, so:

y = 7

11)

x = 5 * √2

x = 5√2

Since the triangle is isosceles, the legs are the same length, so:

y = 5

12)

a = 5√2 * √2

a = 10

Since the triangle is isosceles, the legs are the same length, so:

b = 5√2

Answer: See explanation

Step-by-step explanation:

To convert from 12 hours time to 24 hours time, we've to add 12 to it in the afternoon. Also, the 12 hours clock uses a.m and p.m while the 24 hours doesn't

i. 7:20 am = 07:20

ii. 3:25 pm = 15:25

iii. 1:16 pm = 13:16

iv. 12:51 am = 00:51

Answer:

Step-by-step explanation:

Given the following data;

Points on the x-axis (x1, x2) = (-4, 3)

Points on the y-axis (y1, y2) = (-5, 5)

To find the equation of line in terms of x;

First of all, we would determine the slope of the line;

Mathematically, slope is given by the formula;

[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]

[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the equation, we have;

[tex] Slope, m = \frac {5 - (-5)}{3 - (-4)} [/tex]

[tex] Slope, m = \frac {10}{7} [/tex]

Slope, m = 10/7

Next, we find the equation;

y - y1 = m(x - x1)

y - (-5) = 10/7(x -(-4))

y + 5 = 10/7(x +4)

Answer:

S.A = 147.35 cm²

Step-by-step explanation:

Surface area of the triangular pyramid = base area + ½(perimeter of base*slant height)

Base area = ½*bh

b = 7 cm

h = 6.1 cm

Base area = ½*7*6.1 = 21.35 cm²

Perimeter of triangular base = 7 + 7 + 7 = 21 cm

slant height = 12 cm

Plug in the values into the equation

S.A = 21.35 + ½(21*12)

S.A = 21.35 + 126

S.A = 147.35 cm²

Answer:

  A.  2 square feet

  B.  draw a diagonal; 1 square foot

Step-by-step explanation:

A. The area of a parallelogram is given by the formula ...

  A = bh

Here the base (b) is 3 feet, and the height (h) is 2/3 ft. The area is ...

  A = (3 ft)(2/3 ft) = 2 ft^2 . . . . area of the parallelogram

__

B. Drawing a diagonal (AC or BD) will divide the figure into two congruent triangles. Each triangle has the same base and height as the original parallelogram. The area of one of the triangles is given by ...

  A = 1/2bh

Using the given dimensions, ...

  A = 1/2(3 ft)(2/3 ft) = 1 ft^2 . . . . area of one triangle
