x=

Ill mark brainliest if yall help me and ill make it 20 points

Answers

Answer 1
1) 15 = 5(x + 2)
15 = 5x + 10
15 - 10 = 5x + 10 - 10
5 = 5x
5/5 = 5x/5
1 = x

2) 5n + 34 = -21(1-7n)
5n + 34 = -21 + 147n
5n + 34 = -21 + 147n
5n - 147n + 34 = -21 + 147n - 147n
-142n + 34 = -21
-142n + 34 - 34 = -21 - 34
-142n = -55
-142n/-142 = -55/-142
n = 55/142

Of 570 people, 365 were male and 368 had brown hair. Of those with brown hair, 108 were female. What is the probability that a person was male or had brown hair? Write your answer as a reduced fraction.

Answers

Answer:

473/570

Step-by-step explanation:

No. of male = 365

No. of female = 570-365 = 205

No. of male with brown hair = 260

No. of female with brown hair = 108

the probability that a person was male or had brown hair = 365/570+108/570 = 473/570 [ for or case we add probabilities]

Answer:

Around 83%        473/ 570

Step-by-step explanation:

365 males  + 108 females with brown hair = 473

Divide the number of outcomes desired by the total  number of outcomes 473/570   = 0.829824....... = 82.98.....%

Answer:

Option 3 or Option 4.

Step-by-step explanation:

I have this doubt because actually, a rhombus with a right angle (one) is not necessarily a square. Some rhombuses have one right angle and are still not squares. Now, if the four angles are right, it is a square, but this only says one.

On other hand, a parallelogram with congruent diagonals isn't a square necessarily either. Rectangles have congruent diagonals and are parallelograms.

In case you only can answer with one, I'll say is option 3, hope it helps!

An equilateral triangle has an altitude length of 33 feet. Determine the length of a side of the triangle.

Answers

Answer:

38.11 feet

Step-by-step explanation:

all three corners of an equilateral triangle are 60°

sin 60° = 33/x

0.8660 =33/x

x = 38.11 feet

Relation between the side and the altitude of the equilateral triangle can be given as,

[tex]a=\dfrac{2}{\sqrt{3} } h[/tex]

The length of the side of the equilateral triangle is 38.105 feet.

What is equilateral triangle?

When all the three sides and all the three angle of a triangle are equal, then the triangle is known as Equilateral triangle.  

Relation between the side and the altitude of the equilateral triangle can be given as,

[tex]a=\dfrac{2}{\sqrt{3} } h[/tex]

Here, [tex]a[/tex] is the side of the equilateral triangle and h is the altitude of the equilateral triangle

Given information-

Altitude of the equilateral triangle is 33 feet.

Put the value of altitude in above formula to find the length of the side of the equilateral triangle. Thus,

[tex]a=\dfrac{2}{\sqrt{3} } \times33\\a=38.105[/tex]

Thus the length of the side of the equilateral triangle is 38.105 feet.

Find the surface area of this prism.
Round to the nearest tenth.

Answers

Answer:

The answer is 493.3

Step-by-step explanation:

6.72 x 12.7 x 5.78 = 493.28872

And 493.28872 rounded to the nearest tenth is 493.3 because the original number in the tenth place is 2 and then the digit before that is 8 which in this case is your rounding digit. Round up If the number is greater than 5 and round down if its less than 5. In this case its greater than 5 to that leaves you with 28 so now you have 493.28, 28 rounded to the nearest tenth is 30 and just take the 0 away, as if it didn't exist.

The surface area of the prism is 395 square centimeter.

What is volume?

Volume is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write volume as -

V = ∫∫∫ F(x, y, z) dx dy dz

Given is to fins the surface area of the prism given below.

The given prism is a cuboid. We can write the surface area of the cuboid as -

V = 2(LB + BH + LH)

V = 2(12.7 x 5.78 + 5.78 x 6.72 + 12.7  x 6.72)

V = 2(73.4 + 38.8 + 85.344)

V = 395 square centimeter

Therefore, the surface area of the prism is 395 square centimeter.

Step-by-step explanation:

g(-4) here x = -4

So, we have to take g(x) = x - 2

g(-4) = -4 -2 = - 6

g(1) , here x = 1 ,

So, we have to take g(a)= -x +1

g(-1) = -1 + 1 = 0

g(-4) + g(-1) = -6 +0 = -6

Find the area of a circle with a diameter of 4. How do you find they area of a circle?

To find the area of a circle use the formula [tex]\large\tt A=\pi r^2[/tex] or [tex] \large\tt A=\pi \times r \times r[/tex]

Where π = 3.14 correct to 2 decimal places, r = radius, and d = diameter. The radius is half of the diameter.

[tex]\tt A=\pi r^2[/tex][tex]\tt A=3.14\times 2^2[/tex][tex]\tt A =3.14\times 4[/tex][tex]\tt A={12.56units^2}[/tex]

Therefore, the area of a circle is 12.56 sq. units
