Answer:

2/3

Step-by-step explanation:

When a line is parallel to another, it means that there are never going to be any solutions(they won't ever intersect each other.) To do so, the slope of the lines have to be the same. It doesn't matter what the y-intercept is.

So the slope of the second line is going to be the same as the first line: 2/3

[tex]\dfrac{1}{2}\ gm,\dfrac{1}{5}\ gm,\dfrac{1}{8}\ gm[/tex]

The total weight of the three weights is

[tex]\Rightarrow \dfrac{1}{2}+\dfrac{1}{5}+\dfrac{1}{8}=\dfrac{20+8+5}{40}\\\\\Rightarrow \dfrac{33}{40}\ gm[/tex]

Plz mark as brainllest

Answer:

The answer for radius is 4.2 cm. The answer for diameter is 8.4 cm.

Step-by-step explanation:

If the line cuts halfway through the middle it is a radius, as you can see there. It says 4.2 cm, so that's your radius. If the line is straight through the circle and not cut in half then it is a diameter. The radius is half of the diameter. So if you add 4.2 or multiply 4.2x2 then you get 8.4 which is your diameter.

Answer:

Step-by-step explanation:

option c is the correct answer

The required value of the given logarithmic expression log₂ 16 – log₂ 4 is 2. The correct answer would be an option (C).

There are four basic properties of logarithms:

logₐ(xy) = logₐx + logₐy.

logₐ(x/y) = logₐx - logₐy.

logₐ(xⁿ) = n logₐx.

logₐx = logₓa / logₓb.

According to the problem, we will use some of the basic logarithmic properties,

The logarithmic expression is given in the question, as follows:

log₂ 16 – log₂ 4

We have to determine the value of the given logarithmic expression.

As per the given question, we have

⇒ log₂ 16 – log₂ 4

⇒ log₂ 2⁴ – log₂ 2²

Using property logₐ(xⁿ) = n logₐx,

⇒ 4 log₂ 2 – 2 log₂ 2

Apply the subtraction operation, and we get

⇒ 2 log₂ 2

⇒ 2 (1)

⇒ 2

Thus, the required value of the given logarithmic expression is 2.

Answer:

401.92

Step-by-step explanation:

The formula used the calculate the volume of a cylinder is

πr^2h

π= 3.14

H= 8

r= 4

Volume= 3.14 × 4^2 × 8

= 3.14 × 16×8

= 401.92

Hence the volume is 401.92

Answer:

[tex]3\frac{1}{4}[/tex] inches

Step-by-step explanation:

Height of the tallest conifer = [tex]9\frac{1}{2}[/tex] inches

Height of the shortest conifer = 6 + measure of one segment on the number line

Measure of one segment on the number line = [tex]\frac{6\frac{1}{2}-6}{2}[/tex]

                                                                           = [tex]\frac{\frac{1}{2}}{2}[/tex]

                                                                           = [tex]\frac{1}{4}[/tex]

Therefore, height of the shortest conifer = 6 + [tex]\frac{1}{4}[/tex]

                                                                    = [tex]6\frac{1}{4}[/tex]

Difference in tallest and shortest conifer = [tex]9\frac{1}{2}- 6\frac{1}{4}[/tex]

                                                                    = (9 - 6) + [tex](\frac{1}{2}- \frac{1}{4})[/tex]

                                                                    = 3 + [tex]\frac{1}{4}[/tex]

                                                                    = [tex]3\frac{1}{4}[/tex] inches

1. Mean = 145/5 = 29

Option A is the correct answer

2. Mean = 35 /5 = 7

Option B is the correct answer

Answer:

1. 29 (A) 2. 7 (B)

Step-by-step explanation:

1. 2+57+38+42+6 = 145

145/5 = 29

2. 4+9+7+10+5 = 35

35/5 = 7

Answer:

The length is 12

Step-by-step explanation:

rectangle = 2w + 2l

Substitute 15 with w

2l + 2(15) = 54

Multiple

2l + 30 = 54

Subtract 30 from both side

2l = 24

divide by 2

l = 12

Answer:

gradient = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope (gradient) and c the y- intercept )

Given

8y + 4x = 5 ( subtract 4x from both sides )

8y = - 4x + 5 ( divide the terms by 8 )

y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{5}{8}[/tex] ← in slope- intercept form

with gradient = - [tex]\frac{1}{2}[/tex]

Given a line with gradient m then the gradient of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2

2 is the gradient of a line that is perpendicular to 8y+4x=5​

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane

The slope of line can also be called ad gradient of a line.

The standard form of line or slope intercept form of a line is given by

y=mx+c

where m is the slope of line and c is the y intercept.

The given equation of line is  8y+4x=5​

We need to convert the equation of line to Slope intercept form

8y=5-4x

Divide both sides by 8

y=5/8-4/8x

y=-1/2x+5/8

So m is -1/2.

Two lines are said to be perpendicular if m₁m₂ =-1

if m₁=-1/2

then we need to calculate m₂

-1/2m₂=-1

m₂=2

Hence gradient of a line that is perpendicular to 8y+4x=5​ is 2.

Answer:

(2u+8)(2u+10) inches^2=4u^2+36u+80 inches^2

Step-by-step explanation:

I don't know what the options are. But I'll try to help you anyway. Is that variable for the width of the frame... u? We'll just use u.

So the area of a rectangle is found using length* width. To find the combined area of the mat and the photo, we need the combined length and the combined width.

combined length=u+8+u

(Think of it from the top to the bottom: the top strip has a length of u inches, 8 is given, and the bottom strip is also u inches long.) You can simplify it to get 2u+8 inches.

combined width=u+10+u=2u+10 inches

To find the area, you need to multiply these dimensions.

(2u+8)(2u+10) inches^2

I think this would be your answer for Part B, because it's factored.

I think for Part A, you need to multiply it all out.

=2u(2u+10) + 8(2u+10)

=4u^2+20u + 16u+80

=4u^2+36u+80 inches^2
