Answer:

Step-by-step explanation:

Isaiah Let's solve this by rewriting the actual measurements the two boys have with their uncertainties. Krisann has a measuring tape to the nearest quarter inch. So his measurement may be off by half that, or and eighth of an inch. So his measurement is 27.75 ± 0.125. Isaiah has a measuring tape to the nearest eighth inch. So his measurement may be off by up to a sixteenth of an inch. So his measurement is 27.75 ± 0.0625 Now which is more precise, 27.75 ± 0.125, or 27.75 ± 0.0625? The answer is pretty obvious with 27.75 ± 0.0625 being the more precise measurement. And that value is from Isaiah.

Answer:

Step-by-step explanation:

Isolate the term of x from one side of the equation.

First, add by 5 from both sides.

[tex]\sf{x-5+5\leq10+5}[/tex]

Solve.

Add the numbers from left to right.

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

[tex]\Longrightarrow: \boxed{\sf{x\leq 15}}[/tex]

I hope this helps you! Let me know if my answer is wrong or not.

Let's solve this inequality.

First, we should add 5 to both sides:-

x≤10+5

x≤15

Remember, the "≤" sign means "less than or equal to"

So is x=6 a solution to the inequality x≤15? Will this solution make the inequality true?

Yes.

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)

Geometry properties!

When we look at this photo we see that [tex]a[/tex] and [tex]b[/tex] are on a line, meaning that [tex]a+b=180[/tex].

But because we don't have enough info yet we can't solve for them.

So let's head over to [tex]c[/tex].

For [tex]c[/tex] we see that it is also on a line with a right angle, and 35 degrees. This means that:

[tex]c + 90 + 35 = 180[/tex]

If we solve for [tex]c[/tex], we get:

[tex]c=180-90-35= 55[/tex].

Now we see that [tex]a[/tex] makes a vertical angle with [tex]c[/tex], meaning that angle [tex]a[/tex] is equal to angle [tex]c[/tex].

So now we know what angle [tex]a[/tex] is: [tex]55[/tex]°

Now we can go back to [tex]a + b =180[/tex]

Since we know [tex]a =55\\\text{we can get}\\55+b=180\\b=180-55=125[/tex]

That's it!

Answer:

the answer is 6 cm

Step-by-step explanation:

Here’s one way you can solve this problem.

A zoom setting of one hundred twenty percent means that the dimensions of the new copy will be one hundred twenty percent of the dimensions of the original drawing.

First, write the scale that expresses the ratio of the original percent to the copy percent, one hundred to one hundred twenty.

Then, let h represent the height of the copy and write the ratio of copy to original as five centimeters to h centimeters.

Next, write a proportion that equates the two ratios. One hundred to one hundred twenty equals five to h.

Then, cross multiply the terms of the proportion. One hundred twenty times five equals one hundred h.

Next, multiply to get six hundred equals one hundred h.

Finally, divide both sides by one hundred to find h. h equals six.

So, the longer dimension of the new drawing is six centimeters, which is one hundred twenty percent of five centimeters.

Step-by-step explanation:

A semicircle whose diameter is 20 cm will have an area of 157 cm²

Answer:

Angle C= 79 degrees Angle X = 62 degrees

Step-by-step explanation:

Angle A= 62 degrees Angle B=39 degrees Angle C= ?

Angle X=?                    Angle Y= 39 degrees Angle Z= 79 degrees

Because both triangles share a similar angle (B and Y), meaning they are the same amount of degrees, triangle ABc and triangle XYZ could be similar, and if they are similar Angle X would equal the same as A and Angle C would equal the same as Z, Do you understand? if not message me and i could further explain!

Answer:

yes they are similar

Step-by-step explanation:

Angle C= 79 degrees Angle X = 62 degrees

Answer:

4 lines/sticks + 7 individual squares

Step-by-step explanation:

Decimal = 0.47

We can break 0.47 into 0.4 + 0.07. We can use 4 of the lines/sticks to represent 0.4 because the whole grid is equal to 1. We can use 7 individual squares to represent 0.07 because 1/100 is the same as one of the individual squares.

Answer:

b) adjacent and complimentary

Step-by-step explanation:

Supplementary angles equal 180. Complimentary angles equal 90. 55+35 equals 90 and are next to each other therefore they are adjacent and comlimentary.

a) one unit up = Ix + 2I + 1

b) one unit down = Ix + 2I - 1

c) one unit to the left = Ix + 1I

d) one unit to the right = Ix + 3I

Let the function f(x) and g(x) are two real functions.

And g (x) = f (x) + k, where k is real numbers.

Function can be sketched by shifting f (x), k units vertically.

The direction of shift can be found by the value of k:

if k > 0, the base graph shifts k units up, and

if k < 0, the base graph shifts k units down.

The function provided by the basic function f(x) and the constant

g(x) = f(x - k),

may be drawn by horizontally moving the f(x) k unit coordinates.

The shift's direction depends on the value of k. Specifically,

The base graph moves k units to the right if k > 0, and

The base graph moves k units to the left if k < 0.

The graph of y = |x+2| is a V-shaped graph centered at x = -2.

To translate this graph, we need to modify the equation to shift it up/down or left/right.

Here are the equations for each translation:

a) To shift the graph one unit up, we need to add 1 to the equation:

y = |x+2| + 1

b) To shift the graph one unit down, we need to subtract 1 from the equation:

y = |x+2| - 1

c) To shift the graph one unit to the left, we need to replace x with (x+1) in the equation (since moving left means decreasing x by 1):

y = |(x+1)+2|

Simplifying this gives:

y = |x+3|

d) To shift the graph one unit to the right, we need to replace x with (x-1) in the equation (since moving right means increasing x by 1):

y = |(x-1)+2|

Simplifying this gives:

y = |x+1|

Therefore, all the required values are given above.
