Step-by-step explanation:

1) 2x^2 +5 =167

Subtract the 5 from both sides to get the equation 2x² = 162

Then divide the 2 from both sides to get x² = 81, Then square root from both sides to get x= 9

6) 2(2y +4)²=72

Divide 2 from both sides to get (2y+4)²=36

Then square root that to get 2y+4 = 6

subtract 4 from both sides to get 2y =2

Then divide both sides from 2. Y=2

To solve this question, I have divided the shape into squares and rectangles. Then, I found out the area of each square and rectangle. Lastly, I added up all the areas and found the area of the shape. Please consider looking at the picture uploaded to understand better.

When looking at the picture, we can say that the area is 55 + 120 + 304.

Hence, the area of the shape is 479 yd².

From the ratio gotten, the total cost of the pepper will be $129.90.

Since the students planted 8 tomato plants and 16 pepper plants in a school garden. The ratio will be:

= 8/16 = 1:2

This year, the students planted 15 tomato plants, the number of pepper will be:

= 15 × 2 = 30

Since pepper plants cost $4.33 each, the total cost will be:

= 30 × $4.33

= $129.90

Answer:

0.714

Step-by-step explanation:

P(A or B or C) = P(A) + P(B) + P(C)

=(5/35)+(10/35)+(15/35)

=25/35

=0.714

Probability that a student earns a grade of A, B, or C is equals to 0.86.

" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes."

Formula used

Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]

According to the question,

Given,

Total number of students = 35

Number of students getting grade A = 5

Number of students getting grade B = 10

Number of students getting grade C = 15

Substitute the value in the formula of probability we get,

P(A or B or C) = P(A) + P(B) + P(C)

                      = [tex]\frac{5}{35} +\frac{10}{35} +\frac{15}{35}[/tex]

                      = [tex]\frac{30}{35}[/tex]

                      = 0.8571

                      = 0.86 (decimal rounded to the nearest hundredth)

Hence, probability that a student earns a grade of A, B, or C is equals to 0.86.

Hi, the equation you typed is 10c-5

less than is subtraction and the product of two numbers is multiplying them together.

Answer:

12 quarters 23 dimes

Step-by-step explanation:

x(0.25)+(2x-1)(0.10)=5.30

0.25x+0.2x-0.10=5.30

0.45x=5.40

x=12

12 quarters

12(2)=24-1=23 dimes

Joe has 12 quarters coins and 23 dimes coins .

Equation is a combination of mathematical variables, in which two mathematical expressions are equal.

Let the number of quarters be n,

Therefore the number of dimes will be 2n-1.

Given that,

The total value of dimes and quarters is $5.30.

Write above text in equation form.

(0.25)n+(0.10)(2n-1)=5.30

0.25n+0.20n-0.10=5.30

.45n=5.40

n=12

And 2n-1=23

Means Joe has 12 quarters coin and 23 dimes coins .

Step-by-step explanation:

Draw a horizontal line at the end of the 8 meter horizontal line.

Find the area of the horizontal rectangle

L = 8 + 3

W = 2

Area = L*w

Area = 11*2

area = 22 m^2

Now do the vertical rectangle

L = 8

w = 3

Area = L*w

Area = 8 * 3

Area = 24 m^2

Total Area = 24 + 22 = 46 m^2

Step-by-step explanation:

Let Nathalie's age be x

Let Fred's age be a

x+a=40 yrs•••••1

4x+a=76yrs•••••2

a=40-x

Substitute a for 40-x in equation (2)

a=28

Answer:

Step-by-step explanation:

The given price relations allow us to write two equations involving the prices of the tickets. Those can be solved to find ticket prices.

Let s and c represent the prices of senior and child tickets respectively. Then the described sales can be written as ...

  3s +c = 38 . . . . first day's sales

  3s +2c = 52 . . . second day's sales

__

Subtracting the first equation from the second eliminates the s variable and gives the price of a child ticket:

  (3s +2c) -(3s +c) = (52) -(38)

  c = 14 . . . . . simplify

Then the price of a senior citizen ticket can be found using the first equation:

  3s +14 = 38 . . . . . substitute for c

  3s = 24 . . . . . . . subtract 14

  s = 8 . . . . . . . divide by 3

The price of a senior citizen ticket is $8; the price of a child ticket is $14.

Answer:

the answer is 9.5 cm

Step-by-step explanation:

so CD=CE=BD=AE\

CD=4.6cm

CE=11.5cm

BD=8.3cm so AE=BD times ce=3.8 times 11.5=4.6=9.5cm YOUR WELCOME

The measure of AE is 9.5 cm and the length of AB is 6.3 cm.

Given that, ABC and EDC are straight lines EA is a parallel to DB. EC= 11.5 cm, DC =4.6 cm DB =3.8 cm.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

From the figure,

∠CAE=∠CEA (Corresponding angles of parallel lines are congruent)

∠CBD=∠CDB (Corresponding angles of parallel lines are congruent)

From AA similarity ΔCAE≈CDB

Now, EC/DC = AE/DB

⇒11.5/4.6 =AE/3.8

⇒ AE = (11.5 × 3.8)/4.6

⇒ AE = 9.5 cm

⇒11.5/4.6 =10.5/BC

⇒ BC = (4.6 × 10.5)/11.5

⇒ BC = 4.2 cm

Then, AB=10.5-4.2 = 6.3 cm

Therefore, the measure of AE is 9.5 cm and the length of AB is 6.3 cm.
