How many bases does a triangular prism have?
(if you explain I will give brainlyist)

Answer:

1/30

Step-by-step explanation:

The total number of cards is 150. Subtract the numbers of the other values, 130 and 15 to get the number of $100 cards.

150 -145 = 5

5/150 is the number out of the total.

Simplify to get the probability: 1/30

Answer:

[tex]\displaystyle \boxed{\text{\sf \Large x=-1}}[/tex]

Step-by-step explanation:

Add 1 to both sides

[tex]x^2+2x+1=0[/tex]

Use quadratic formula with a=1, b=2, c=1

[tex]\displaystyle x=\frac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]

[tex]\displaystyle x= \frac{-(2) \pm \sqrt{(2)^2-4(1)(1)} }{2(1)}=-1[/tex]

Step-by-step explanation:

(18 - 6)/(4-2)= 12/2= 6 slope

y - 6 = 6(x - 2)

y - 6 = 6x - 12

y = 6x  - 6

y int= (0, -6)

Step-by-step explanation:

The centroid is the average of the vertex coordinates:

  (A +B +C)/3 = ((2, 3) +(8, 1) +(5, 7))/3 = (2+8+5, 3+1+7)/3 = (5, 3 2/3)

Answer:

46940064

Step-by-step explanation:

1)

The angle of inclination is the angle between the horizontal and the ramp.

Using the sine ratio in the right triangle formed by the ground and the ramp

let x be the angle of inclination, then

sinx = \frac{opposite}{hypotenuse}

hypotenuse

opposite

= \frac{0.7}{4.2}

4.2

0.7

, then

x = sin^{-1}sin

−1

(\frac{0.7}{4.2}

4.2

0.7

) ≈ 10° ( to the nearest degree )

(2)

Again there is a right triangle between the ground and the vertical height of the kite, with hypotenuse being length of string.

let y be the height of the kite and x the horizontal distance, then

sin27° = \frac{opposite}{hypotenuse}

hypotenuse

opposite

= \frac{y}{176}

176

y

( multiply both sides by 176 )

176 × sin27° = y , then

y ≈ 80m ( to the nearest metre ) ← height of kite

and

cos27° = \frac{adjacent}{hypotenuse}

hypotenuse

adjacent

= \frac{x}{176}

176

x

( multiply both sides by 176 )

176 × cos27° = x , then

x ≈ 157m ( to the nearest metre ) ← horizontal distance

Answer:

A) 24

Step-by-step explanation:

Answer:

73°

Step-by-step explanation:

Here we use trigonometry to find the angle. The building and the ground form a perpendicular angle, with the ladder acting as the hypotenuse, we get a right angle. We know the length of adjacent leg from the angle, and the length of the hypotenuse. In this case, we use cosine since cos = adjacent length/hypotenuse length. So cos x= 7/24. To isolate x, we use the inverse function of cos, cos^-1. Then x= cos^-1 (7/24) or 73°.

Answer:

any equation that have the slope of -2

A line which is perpendicular to the line x – 2y = -14 will have a slope of -2

The slope of a line is a measure of its steepness.

Given an equation of a line  x – 2y = -14

We know that, the slope of a line perpendicular to another line will have a slope of its negative reciprocal.

Therefore, slope of the line perpendicular to the line x – 2y = -14  will be -2

Hence, equation of the line perpendicular to the line x – 2y = -14 will have a slope of -2

Answer:

400

Step-by-step explanation:

Solution for 500 is what percent of 125:

500:125*100 =  

(500*100):125 =  

50000:125 = 400  

Now we have: 500 is what percent of 125 = 400  

Question: 500 is what percent of 125?  

Percentage solution with steps:  

Step 1: We make the assumption that 125 is 100% since it is our output value.  

Step 2: We next represent the value we seek with [tex]x%[/tex].  

Step 3: From step 1, it follows that $100%=125$.

Step 4: In the same vein, $x%=500$.

Step 5: This gives us a pair of simple equations:

100%=125(1)

x%=500(2)

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left-hand side) of both equations have the same unit (%); we have

[tex]\frac{100\%}{x\%}=\frac{125}{500}[/tex]

Step 7: Taking the inverse (or reciprocal) of both sides yields

[tex]\frac{x\%}{100\%}=\frac{500}{125}[/tex]

[tex]\Rightarrow x=400\%[/tex]

Therefore, 500 is 400% of 125

Answer:

(2x - 3)/(x +4)

Step-by-step explanation:

Given the expression 4x^2 - 9/2x^2+11x+12

Simplify the numerator

4x^2 - 9 = (2x)^2 - 3^2

Recall that a^2 - b^2 = (a-b)(a+b)

Hence 4x^2 - 9 = (2x - 3)(2x + 3)

The denominator

2x^2+11x+12

Factorize

2x^2+11x+12 = 2x^2+8x + 3x+12

=2x(x + 4) + 3(x + 4)

= (2x + 3)(x + 4)

Hence

4x^2 - 9/2x^2+11x+12 =  (2x - 3)(2x + 3)/(2x + 3)(x + 4)

= (2x - 3)/(x +4)
