Answer:

4.2

Step-by-step explanation

Delta

The area of the triangle STU to the nearest of a square centimeter is 4.2 cm².

area of the triangle = 1 / 2 tu sin S

where

Therefore,

t = 3.4 cm

u = 6.9 cm

∠S = 21°

Hence,

area of the triangle = 1 / 2 × 3.4 × 6.9 sin 21°

area of the triangle = 23.46 sin 21 / 2

area of the triangle = 23.46 × 0.35836794954 / 2

area of the triangle = 8.40731209633 / 2

area of the triangle = 4.20365604817

area of the triangle = 4.2 cm²

Answer:

5.0/5

Step-by-step explanation:

Answer:

10 / 13

Step-by-step explanation:

You first have to add all of the coins together.

4 + 3 + 6 = 13 coins

So, now you have the total amount of coins. ut, you need to find the probability of getting a dime or a penny. So, you just have to add the pennies and dimes.

4 + 6 = 10 pennies and dimes

And you just have put 10 over 13 and that is your probability of getting a dime or penny.

Answer:

missing angle = 70 degrees

Step-by-step explanation:

180 -120 =60, because supplemenatery angles add up to 180 degrees.

sum of all angles of a triangle = 180. so 180-60-50=70 degrees

Answer:

? = 70°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

120° is an exterior angle of the triangle, then

? + 50° = 120° ( subtract 50° from both sides )

? = 70°

Answer:

a) (0, 3.5)

b) (12, 11)

Step-by-step explanation:

The points through which the graph of the linear equation passes are;

(-4, 1) and (4, 6)

The slope of the equation of a straight line passing through points (x₁, y₁), and (x₂, y₂), 'm', is given as follows;

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

∴ The slope of the equation, m = (6 - 1)/(4 - (-4)) = 5/8 = 0.625

The equation of th line in point and slope form is therefore;

y - 1 = 0.625·(x - (-4))

∴ y = 0.625·(x - (-4)) + 1 = 0.625·x + 3.5

y = 0.625·x + 3.5

Therefore;

a) When x = 0, y = 0.625 × 0 + 3.5 = 3.5

∴ The point (0, 3.5) is a solution

b) When x = 12, we have, y = 0.625 × 12 + 3.5 = 11

∴ The point (12, 11) is a solution

However;

c) When x = 8, we have, y = 0.625 × 8 + 3.5 = 8.5

∴ The point (8, 5) is not a solution

d) When x = -6, we have, y = 0.625 × (-6) + 3.5 = -0.25

∴ The point (-6, 0) is not a solution

Therefore;

The points which are solutions are;

(0, 3.5) and (12, 11)

Answer: 1/4

Step-by-step explanation:

He has a 1 in 4 chance to roll a number less than three since there are 3 consonants and 1 vowel and all sides are the same size

We can write that the probability that Riley rolls a number less than 3 and lands on a consonant as 1/2.

Probability of an event is the ratio of number of favorable outcomes to the total number of outcomes. Probability is a measure of how likely an event is going to happen.

Given is that Riley is playing a game that requires rolling a number cube numbered 1-6 and spinning with 3 consonants and 1 vowel. The sections of the spinner are all the same size.

It is asked to find the probability that Riley rolls a number less than 3 and lands on a consonant.

We can write the probability that Riley rolls a number less than 3 and lands on a consonant as -

P{number less than 3 and lands on a consonant} = n{F}/n{T}

P{number less than 3 and lands on a consonant} = n{F}/n{T}

P{number less than 3 and lands on a consonant} = 5/10

P{number less than 3 and lands on a consonant} = 1/2

Therefore, we can write that the probability that Riley rolls a number less than 3 and lands on a consonant as 1/2.

Answer:

Area of the shaded region = 6.88 cm²

Step-by-step explanation:

Area of the shaded region = Area of the rectangle - Area of the semicircle

Area of the rectangle = Length × Width

Length of the rectangle = AD = 8 cm

Width of the rectangle = OP = 4 cm [OP, OB and OC are the radii of the circle which are equal in measures]

Area of the rectangle = 8 × 4 = 32 cm²

Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]

                                     = [tex]\frac{1}{2}\pi (OP)^{2}[/tex]

                                     = [tex]\frac{1}{2}\pi (4)^{2}[/tex]

                                     = 25.12 cm²

Area of the shaded region = 32 - 25.12

                                              = 6.88 cm²

Given:

The quadratic equation is:

[tex]x^2-32x+54=0[/tex]

It can be written as [tex]-p=202[/tex].

To find:

The value of p in the rewritten equation.

Solution:

We have,

[tex]x^2-32x+54=0[/tex]

Isolate the constant term.

We need to make 202 on the right side. So, add 256 on both sides.

[tex]x^2-32x+256=-54+256[/tex]

[tex]x^2-32x+256=202[/tex]

[tex]-(-x^2+32x-256)=202[/tex]

Let [tex]-x^2+32x-256=p[/tex], then

[tex]-p=202[/tex]

Therefore, the value of p is [tex]-x^2+32x-256[/tex].

The given equation can be written as:

[tex]54=-x^2+32x[/tex]

Adding 148 on both sides, we get

[tex]54+148=-x^2+32x+148[/tex]

[tex]202=-(x^2-32x-148)[/tex]

Let [tex]x^2-32x-148=p[/tex], then

[tex]202=-p[/tex]

Therefore, the another possible value of p is [tex]x^2-32x-148[/tex].

since the table mostly gives us the answer, i think its:

[tex]\frac{100}{x}[/tex]=[tex]\frac{200}{22.4}[/tex]

⬆⬆⬆⬆that's your answer <3333

Answer:

Step-by-step explanation:

100 / x    = 200/22.4

cross multiplication

200x = 22.4 x 100

200x = 2,240

divide by 200

x = 11.2

It makes sense since 100 is half of 200 then 11.2 is half of 22.4

Answer:

m1= 82

m2=98

m3=82

Step-by-step explanation:

Angle m4 is supplementary with angle m1 so their values add up to 180

180-98=82

Angle m3 is opposite of m1 and is the same value, it is also supplementary to m4 so you can find the value that way as well.

Angle m3 is opposite of m4 so it is the same value.  It is supplementary to m1 and m3, so it must be 98 through that logic as well.
