Frank is going to plant b vegetable seeds in one garden and 5b + 10 vegetable seeds in another . How many seeds is frank going to plant ?

Answers

The number of seeds that Frank will plant, expressed in algebraic form, is: 6b + 10.

Algebraic Expressions

  • Given that, b and (5b + 10) are the seeds to be planted by Frank in different gardens, the number of seeds Frank is going to plant can be expressed in algebraic form by adding both expressions together.
  • Like terms with the same variables are added together.

Thus:

b + 5b + 10

6b + 10

Therefore, the number of seeds that Frank will plant, expressed in algebraic form, is: 6b + 10.

What number is 32% of 1,000?

Answers

the answer is 320.00. i hope this helped.
Your answer is 320, because you use proportions

32/100

___/1000

32 times 1000 = 32,000

? times 100 should = 32,000

To find this, divide 32,000 by 100.

Final Answer: 320 is 32% of 1,000 :-)

Choose the equation that represents a line that passes through points (−6, 4) and (2, 0). x + 2y = 2 2x − y = −16 x + 2y = −8 2x + y = 4

Answers

Answer:

x + 2y = 2

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

The formula of a slope:

m=(y_2-y_1)/(x_2-x_1)

================================================

We have the points (-6, 4) and (2, 0).

Substitute:

m=(0-4)/(2-(-6))=(-4)/(8)=-(1)/(2)

Put the value of the slope and coordinates of the point (2, 0) to the equation of a line:

0=-(1)/(2)(2)+b

0=-1+b          add 1 to both sides

1=b\to b=1

The equation of a line in the slope-intercept form:

y=-(1)/(2)x+1

Convert to the standard form Ax+By=C

y=-(1)/(2)x+1           multiply both sides by 2

2y=-x+2             add x to both sides

x+2y=2

Answer:

Option 1.

Step-by-step explanation:

It is given that the line passes through the points (-6,4) and (2,0).

If a line passes through two points, then the equation of line is

y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)

Using the above formula the equation of line is

y-(4)=(0-4)/(2-(-6))(x-(-6))

y-4=(-4)/(8)(x+6)

y-4=(-1)/(2)(x+6)

Muliply both sides by 2.

2y-8=-x-6

x+2y=-6+8

x+2y=2

Therefore, the correct option is 1.

A 14 foot ladder is used to scale a 13 foot wall.At what angle of elevation must the ladder be situated in order to reach the top of the wall?

Answers

The angle of elevation must be 68.202 degrees

Solution:

Given that, 14 foot ladder is used to scale a 13 foot wall

We have to find the angle of elevation must the ladder be situated in order to reach the top of the wall

The figure for this solution is attached below

The ladder, wall and the ground forms a right angled triangle

ABC is a right angled triangle

AB is the height of wall = 13 feet

AC is the length of ladder = 14 feet

We have to find the angle of elevation

Let the angle of elevation be "x"

For right angled triangle ABC, We can use the definition for sine

\sin x=\frac{\text { opposite }}{\text { hypotenuse }}

Here, in figure, opposite = AB and hypotenuse = AC

\sin x=(A B)/(A C)\n\n\sin x = (13)/(14)\n\n\sin x = 0.9285\n\nx = sin^(-1)(0.9285)\n\nx = 68.202

Thus the angle of elevation must be 68.202 degrees

The angle of elevation the ladder will be situated in order to reach the top of the wall is 68°.

What is a right triangle?

A right triangle has one of its angles as 90 degrees. The angle of elevation can be found using trigonometric ratios.

Therefore, the angle of elevation can be calculated as follows;

The length of the ladder is the hypotenuse.

The opposite side is the height of the wall.

Therefore,

sin ∅ = opposite / hypotenuse

sin ∅ = 13 / 14

∅ = sin⁻¹ 0.92857142857

∅ = 68.2129901712

∅ = 68°
