If 4 students share 30 ft.² wall equally how many square feet of the wall will be painted by each student

Answer:

The Answer is A. 3y=2

Step-by-step explanation:

1) combine like terms

7y + 7 = 9 + 2y + 2y

7y +7 = 9 + 4y

Subtract 4y on both sides

3y +7 = 9

Subtract 7 on both sides

3y = 2 because 9 - 7 = 2

Answer:

The Answer is A.

I did the work.

Answer:

81 million

Step-by-step explanation:

A = Pe^rt

Let's break this equation down.

A is the total you will have.

P is the starting value.

R is the rate

T is the time.

Let's find the rate first.

74000000 = 70000000e^7r

Divide each side by 70mil

74000000/70000000 = e^7r

Then take the ln() of each side.

ln(74000000/70000000) = 7r

0.0556 = 7r

r = 0.0079

Now we can find how many people will be there in 2010.

A = 70,000,000e^(19 * 0.0079)

A = 81336530.2373

Now we round to the nearest million, leaving us with 81 million.

The equation 6*1=6 is an illustration of the Identity Property of Multiplication which states that any number multiplied by 1 yields the original number.

The question is asking about the mathematical property illustrated by the equation 6*1=6. In this case, the answer is the Identity Property of Multiplication. The Identity Property of Multiplication states that any number multiplied by 1 will result in the original number. In other words, 1 is the identity for multiplication because multiplying any number by 1 does not change the number's value. Hence, 6*1 still yields 6, validating this property.

Answer:

(x - 5)² + (y + 2)² = 9

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (5, - 2) and r = 3, thus

(x - 5)² + (y - (- 2))² = 3², that is

(x - 5)² + (y + 2)² = 9 ← equation of circle

Answer:

Part a) [tex]114.3\ yd^{2}[/tex]

Part b) [tex]49.5\ yd^{2}[/tex]

Step-by-step explanation:

Part a) we know that

The area of the shaded figure is equal to the area of semicircle plus the area of a triangle

Find the area of semicircle

The area of a semicircle is equal to

[tex]A=\frac{1}{2}\pi r^{2}[/tex]

we have

[tex]r=5\ yd[/tex]

substitute

[tex]A=\frac{1}{2}\pi (5)^{2}=12.5 \pi\ yd^{2}[/tex]

Find the area of triangle

The area of the triangle is equal to

[tex]A=\frac{1}{2}(b)(h)[/tex]

we have

[tex]b=15\ yd[/tex]

[tex]h=5(2)=10\ yd[/tex] -----> the height of triangle is equal to the diameter of semicircle

substitute

[tex]A=\frac{1}{2}(15)(10)=75\ yd^{2}[/tex]

Find the area of the shaded figure

[tex]12.5 \pi\ yd^{2}+75\ yd^{2}=(12.5 \pi+75)\ yd^{2}[/tex]

assume

[tex]\pi=3.14[/tex]

[tex](12.5(3.14)+75)=114.3\ yd^{2}[/tex]

Part b) we know that

The area of the shaded figure is equal to the area of the triangle minus the area of the circle

Find the area of the circle

The area of the circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=5\ yd[/tex]

substitute

[tex]A=\pi (5)^{2}=25 \pi\ yd^{2}[/tex]

Find the area of triangle

The area of the triangle is equal to

[tex]A=\frac{1}{2}(b)(h)[/tex]

we have

[tex]b=16\ yd[/tex]

[tex]h=16\ yd[/tex]

substitute

[tex]A=\frac{1}{2}(16)(16)=128\ yd^{2}[/tex]

Find the area of the shaded figure

[tex]128\ yd^{2}-25 \pi\ yd^{2}=(128-25 \pi)\ yd^{2}[/tex]

assume

[tex]\pi=3.14[/tex]

[tex](128-25(3.14))=49.5\ yd^{2}[/tex]

a) The area of the shaded figure [tex]114.3yd^{2}[/tex]

b) The area of the shaded figure=[tex]49.5yd^{2}[/tex]

Part a) The area of the shaded figure= (the area of semicircle)+ (the area of a triangle)

Area of semicircle= [tex]A=\frac{\pi r^{2} }{2}[/tex] where r = radius = 5

[tex]A=\frac{\pi 5^{2} }{2} =39.3 yd^{2}[/tex]

The area of the triangle= [tex]\frac{1}{2} base *height[/tex]

base = 15

height=10

The area of the triangle= [tex]\frac{1}{2}*15 *10 =75 yd^{2}[/tex]

The  area of the shaded figure=39.3+75= [tex]114.3yd^{2}[/tex]

Part b) The area of the shaded figure =( the area of the triangle) -(area of the circle)

The area of the triangle=[tex]\frac{1}{2} base *height[/tex]

base and height = 16

Area=[tex]\frac{1}{2} *16*16=128yd^{2}[/tex]

The area of the circle=[tex]\pi r^{2} =3.142*5^{2} = 78.55 yd^{2}[/tex]

[tex]128 yd^{2} -78.55 yd^{2} =49.5yd^{2}[/tex]

Answer:

Step-by-step explanation:

Answer:

83 in²

Step-by-step explanation:

To calculate, add the areas of all three shapes that make up the polygon.

Area of rectangle = L×W = 5×8 = 40 in².

Area of top triangle = 1/2×b×h = 1/2×8×7=28 in².

Area of triangle on the right = 1/2×6×5 = 15 in².

Total area = 40+28+15 = 83 in²

The correct answer is 950 miles because $457.50 - $220.00 = $237.50 and $237.50 divided by $0.25 = 950

Hope this helps.

If a car rental agency charges $220.00 per week and an additional $0.25 per mile, you could travel up to 950 miles in one week for a total cost of $457.50. The calculation was done by subtracting the base fee from the total budget and then dividing it by the cost per mile.

The subject here is how to solve an algebraic problem involving the cost of car rental and the distance traveled. In this situation, the rental car agency charges a weekly rental fee of $220.00 and an additional $0.25 cost per mile driven. So to find out how many miles can be driven in a week for a total cost of $457.50, we'll need to perform a two-step calculation.

First, subtract the base fee from the total amount: $457.50 - $220.00 = $237.50. This is the total amount you have left for the mileage cost.

Second, divide this amount by the cost per mile. So, $237.50 / $0.25 = 950 miles. Therefore, for a total cost of $457.50, you could travel up to 950 miles in one week.

Answer:

Draw a line. Label one endpoint M and the other P. Go half way between the two and label it O.

34z = 36z - 7

MO = 119

Step-by-step explanation:

A line segment with a midpoint means the segment has been divided into two equal segments. This means each segment is equal to the other OM = OP.

You can solve for z by setting them equal to each other.

34z = 36z - 7

-2z = -7

z = 7/2

To find MO, substitute z = 7/2 into the equation OM = 34z.

OM = 34(7/2) = 238/2 = 119

A) 6 square units :)

Answer:

Total area of figure =  6 square units.

Step-by-step explanation:

Given : geometric figure.

To find : Which BEST approximates the area of the geometric figure.

Solution : We have given that geometric figure.

We can see from given figure there are 2 full square and 4 half square and 2 more than half square and 2 square are less than half cover in closed figure.

Since , we ignore the square less half square,

Then area 2 full square =  2 units.

Area of 4 half square  = 2 units.

2 more than half square =  2 units.

Total area of figure = 2 +2 + 2 = 6 square units.

Therefore, Total area of figure =  6 square units.

Answer:

Option D. two complex roots

Step-by-step explanation:

we know that

In a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] the discriminant D is equal to

[tex]D=(b^{2}-4ac)[/tex]

in this problem we have

[tex]3x^{2} -2x+1=0[/tex]  

so

[tex]a=3\\b=-2\\c=1[/tex]

substitute the values

[tex]D=(-2^{2}-4(3)(1))[/tex]

[tex]D=(4-12)[/tex]

[tex]D=-8[/tex]

The discriminant is negative

therefore

The quadratic equation has two complex roots

Final answer:

The equation 3x² - 2x + 1 = 0 has a negative discriminant of -8, indicating that it does not have real roots but instead has two complex roots.Therefore, the correct answer is D. two complex roots.

Explanation:

To determine the nature of the roots for the equation 3x²- 2x + 1 = 0, we need to calculate the discriminant, which is given by b² - 4ac. Here, a = 3, b = -2, and c = 1. Substituting these values into the discriminant formula gives us (-2)² - 4(3)(1) = 4 - 12 = -8. Since the discriminant is negative, the equation does not have real roots. Instead, it has two complex roots.

Therefore, the correct answer is D. two complex roots.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(2x−17)+4=−3(3+x)

4x+−34+4=−9+−3x  {distribute}

4x+−30=−3x−9   {combine like terms}

Step 2: Add 3x to both sides.

4x−30+3x=−3x−9+3x

7x−30=−9

Step 3: Add 30 to both sides.

7x−30+30=−9+30

7x=21

Step 4: Divide both sides by 7.

7x/7=21/7

x=3

4x - 3x = -9 + 30 2 (2x - 17) + 4 = -3 (3 + x)

So, we are going to DISTRIBUTE

Lets work on the left side of the equation first

Multiply 2 on the out side of the parenthesis by what is on the inside

2 x  2x = 4x

2 x  -17 = -34

So on the left side we now have

4x - 34 + 4

add 4

4x - 30

Let's do the same thing on the other side

-3  x  3 = -9

-3 x  X = 3x

Now let's put everything together

4x - 30 = -9 + 3x
