Step-by-step explanation:

1.25x + 2.5y + 0.5z ≤ 28.5

is your inequality

Answer:

the answer would be answer d.5v+4

Angles: 42°, 114°, 24°, 30°, 150°.

First, since it's given the angle PRS=98 degrees we can find x.

(3x-8)+(2x+6)=98 we can solve for x

after solving this we find that

x=20

Now we can solve for angle QRS

2x+6 plug in our values and we get

40+6, which equals 46 degrees

Answer:

5/4

Explanation:

coordinates given (0,0) and (8,10)

How to find unit rate?

use this formula:

(y2-y1)/(x2-x1)

using the formula:

→(10-0)/(8-0)

→ 10/8

→ 5/4

→ 1.25

Answer:

5/4 cm/s

Step-by-step explanation:

The gradient (slope) of the line is equal to the speed of the object.

Gradient = change in y ÷ change in x

Using the two given points (0, 0) and (8, 10):

⇒ speed = (10 - 0) ÷ (8 - 0) = 5/4 cm/s

The question is related to an arithmetical sequence where common difference is 2.

(a-2) +a + (a+2) =3a=69

a=23

So three odds are

Answer:

B. -94.94

Step-by-step explanation:

Substitute given value into function and evaluate

Answer:

-94.94

Step-by-step explanation:

The answer is -94.94. First you put -4.2 as x, so 23.2*-4.2 which gives you -97.44. Then you do (-97.44)+22.5. Which gives you the answer -94.94.

Answer:

x=14

Step-by-step explanation:

[tex]2x-4=24[/tex]

[tex]2x-4+4=24+4[/tex] (Add 4 to both sides)

Answer:

4.41 cm

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

61.2 = pi r^2

Using 3.14 for pi

61.2 / 3.14 = r^2

19.49044586 = r^2

Take the square root of each side

sqrt( 19.49044586) = sqrt(r^2)

4.414798507 = r

To 2 decimal places

Answer:

Identify a1 and r for the geometric sequence

defined by a Subscript n Baseline = negative 256 (negative one-fourth) Superscript n minus 1

a1 =

-256

 r =

-1/4

Approximate the sum of the first 17 terms to the nearest tenth.

Sum =

-204.8

Step-by-step explanation:

The value  [tex]a_1[/tex] is -256.

The value  r = -1/4

A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.

Example:

2, 4, 8, 16 is a geometric sequence.

We have,

In a geometric sequence,

Each term is obtained by multiplying the preceding term by a constant factor, which is called the common ratio (r).

So,

The nth term of the sequence.

[tex]a_n[/tex] = -256 x [tex](-1/4){n-1}[/tex]

Now,

[tex]a_1[/tex] = -256 x [tex](-1/4)^{1 -1}[/tex]

   = -256 [tex](-1/4)^0[/tex]

   = -256 x 1

   = -256

[tex]a_2[/tex] = -256 x [tex](-1/4)^{2-1}[/tex]

   = -256 x [tex](-1/4)^1[/tex]

  = -256 x -1/4

  = 64

Now,

[tex]a_1[/tex] r = [tex]a_2[/tex]

-256 x r = 64

r = 64 / -256

r = -1/4

Therefore,

[tex]a_1[/tex]= -256 and r = -1/4

Answer:

3/14 in decimal is 0.21428571428571

3/14 percent is 21.4

Answer:

(a.) 27^4/3 = 81, (b.) 36^3/2 = 216, (c.) (1/8)^2/3 = 1/4, (d.) 128^5/7 = 32

Step-by-step explanation:

All these expressions can be converted in square roots.

In order to do this, we can picture the fractional exponents as exponent / index

(a.) So for this first problem, we would have the cube root of [tex]27^{\frac{4}{3} }[/tex] or

[tex]\sqrt[3]{(27)^{4} }[/tex].

We must do the equation inside the radical first (i.e., [tex](27)^{4}[/tex]) to get [tex]\sqrt[3]{531,441}[/tex] = 81

We can follow these same steps for the remaining equations:  

(b.) [tex]36^{\frac{3}{2} }[/tex] = [tex]\sqrt{(36)^3}[/tex] = [tex]\sqrt{46,656}[/tex] = 216

(c.) [tex](\frac{1}{8})^\frac{2}{3}[/tex] = [tex]\sqrt[3]{(\frac{1}{8})^{2} }[/tex] = [tex]\sqrt[3]{(\frac{1^2}{8^2}) }[/tex] = [tex]\sqrt[3]{(\frac{1}{64}) }[/tex] = [tex]\frac{1}{4}[/tex]

(d.) [tex]128^{\frac{5}{7} }[/tex] = [tex]\sqrt[7]{(128)^{5} }[/tex] = 32

The points on the graph for the amount of strawberries picked by Annamarie are (0, 11), (10, 38.5).

(10, 38.5)

38.5/10 = 3.85

Annamarie pays $3.85 per basket.

y = 3.25x + 5.5

(3.25, 5.5)

The amount of strawberries picked by Bri is (3.25, 5.5).

Bri pays $5.50 per basket.

The farm where Bri chose to pick strawberries charges more for them so A and B are not the answer.

Annamarie pays $3.85 per basket so C is not one of the answers.

Using the perimeter formula of the Isosceles triangle the equation 2x + 2.1 = 7.5 is derived. The correct option is D.

Triangle is a polygon that has three sides. The sum of the angle of the triangle is 180 degrees. The two sides of the triangle are equal.

Given

The isosceles triangle has a perimeter of 7.5 m.

We know the perimeter of the Isosceles triangle.

Perimeter = Sum of all sides of the triangle

Let the sides be x and y and

And let y be the shortest side.

For y = 2.1 m, the equation will be

[tex]\rm Perimeter = x + x +y\\[/tex]

On simplifying the equation, we get

2x + 2.1 = 7.5

The required equation is 2x + 2.1 = 7.5.

Thus, option D is correct.
