Answer:

180 cm

Step-by-step explanation:

Number of trials per team = 3

Distance per trial for team D's car is the same for each trial, let distance = x

Distance per trial for team C's car is 1cm farther than team D's distance and the same for each trial, hence, distance = x + 1 per trial

Total distance traveled by C = 543 cm

This means :

(x + 1) + (x + 1) + (x + 1) = 543

3x + 3 = 543

3x = 543 - 3

3x = 540

x = 540 / 3

x = 180

Hence, distance traveled per trial for team D's car = x = 180 cm

Answer:

The two possible outcomes are 4 and -12, so 4

Step-by-step explanation:

The greatest value of x  is 4.

Factorization is when you break a number down into smaller numbers that, multiplied together, give you that original number. When you split a number into its factors or divisors, that's factorization.

Given equation

⇒ [tex]x^{2} +8x-30 = 18[/tex]

⇒ [tex]x^{2} +8x-30-18=0[/tex]

⇒ [tex]x^{2} +8x-48=0[/tex]

⇒ [tex]x^{2} +12x-4x-48=0[/tex]

⇒ [tex]x(x+12)-4(x+12)=0[/tex]

⇒ [tex](x+12)(x-4)=0[/tex]

x = -12 and x = 4

Hence, the greatest value of x  is 4.

Step-by-step explanation:

The sides GH and FH are congruent, so Δ FGH is isosceles and the 2 base angles G and F are also congruent, then

∠ F = 65° → A

Answer:

A

Step-by-step explanation:

since it is on sale for 27%, multiply $28 by 70% (0.7) to find the total amount of money the shirt costs now that it is on sale (since it's on sale for 30% off)

$28*0.7=$19.60

Answer:

$19.60

Step-by-step explanation:

First, find 30% of $28.  :)

To do this, multiply 28 by 0.3. (30% is the same thing as 3/10 or 0.3)

28 x 0.3 = 8.4.

30% of 28 is 8.4.

Next, subtract $8.4 from $28. (Shirt on sale for 30% off)

28 - 8.4 = $19.60

Have a great day!

Answer:

X= 130°

Step-by-step explanation:

360°= x°+107°+79°+44° (sum of angles in a quadrilateral)

360°= x°+230°

X= 360°-230°

X= 130°

Answer:

[tex]A=830\ ft^2[/tex]

Step-by-step explanation:

Given that,

The length of one base is 37 feet, and the length of the other base is 46 feet. The height is 20 feet.

We need to find the area of this section of the deck that is shaped like a trapezoid.

The area of a trapezium is given by :

[tex]A=\dfrac{a+b}{2}\times h[/tex]

a = 37 ft, b = 46 ft and h = 20 ft

Put all the values,

[tex]A=\dfrac{37+46}{2}\times 20\\\\A=830\ ft^2[/tex]

So, the area of this section of the deck is equal to [tex]830\ ft^2[/tex].

Answer:

x = -7

y = 9

Step-by-step explanation:

x + y = 2

x - y = -16

substitute '2-x' for 'y'

x - (2-x) = -16

x - 2 + x = -16

2x - 2 = -16

2x = -14

x = -7

-7 + y = 2

y = 9

Answer:

Supplementary angles add to 180 degrees. So of the measure of the angle is x, the measure of its supplement is 2x. Angle = 60, supplement = 120

Step-by-step explanation:

Answer:

139.5º

Step-by-step explanation:

The sum of supplementary angles is 180º

s + 40.5 = 180

Subtract 40.5 from both sides

s = 139.5º

Answer:

x=125

Step-by-step explanation:

Using the definition of supplementary angles, the value of x in the given diagram is: 45.

Supplementary angles equals 180 degrees when added together.

(2x + 40)° and (3x - 85)° are supplementary angles. Therefore:

(2x + 40) + (3x - 85) = 180

Solve for x

2x + 40 + 3x - 85 = 180

Add like terms

5x - 45 = 180

5x = 180 + 45

5x = 225

x = 225/5

x = 45

The value of x is: 45.

Answer:

Because Cosine range is (-1,1) and secant range is (-infinity,1) u (1, infinity)

Answer:

x = 48 degrees

Step-by-step explanation:

This triangle is an isosceles which means that two of the angles are the same and all triangles add up to 180 degrees so we take the two angles we know and add them

66 + 66 = 132

Then we subtract that number from 180 to find the third angle

180 - 132 = 48

Answer:

x = 48°

Step-by-step explanation:

Since the legs of the triangle are congruent then the base angles are congruent, both 66° , then

x = 180° - (66 + 66)° = 180° - 132° = 48°

Answer:

B. x=6

The probability of drawing a red face card from a deck of cards is 3/26

Explanation:

In a deck of cards, there are 6 red-faced cards.

Probability = No. of favourable events / Total no. of events

So, the probability of drawing a red-faced card is 6 out of 52 cards.

Thus, the probability of drawing a red face card from a deck of cards is 6/52 = 3/26.
