Help meee pleaseeeee

Answer:

i think its the last one

Step-by-step explanation:

Alright, lets get started.

Please take a look at the diagram attached.

The reference angle of 75 will be 75

As it is mentioned that the angle intersects the unit circle means r = 1

So, finding cos

cos 75 = [tex]\frac{X}{r}[/tex]

cos 75 = [tex]\frac{0.259}{1}[/tex]

cos 75 = 0.259 is the Answer

Answer:

D. 20°

Step-by-step explanation:

The entire angle = 90 degrees you can tell that from the corner indicator

Set the two expressions equal to 90

(3x+10) + (x) = 90

Combine like terms

4x + 10 = 90

Subtract 10 from both sides to cancel it out

4x = 80

Divide each side by 4

x = 20

Check it by substituting x for 20

3(20) + 10 = 70     x = 20     70 + 20 = 90

Answer:

D. 20degrees

Step-by-step explanation:

This is a Complementary Angle so it will equal 90.

3x + 10 + x = 90

4x + 10 = 90

90 - 10

= 80

4x = 80

80 / 4

x = 20

Answer:

200

Step-by-step explanation:

I started by having the same units on both sides of the expression:

1 m = 100 cm

1cm = 2(100cm)

I then simplified the equation to find the scale:

1cm = 200cm

Answer:

x=13

Step-by-step explanation:

mugs=x

key=y

x+y=21         8.5x2.75 =132.50

y=  -x+21

8.5x + 2.75 (-x + 21) = 132.50

8.5x - 2.75 + 57.75 = 132.50

5.75x = 74.75

x= 13

Answer:

he bought 13 coffee mugs and 8 key chains.

Step-by-step explanation:

How about we solve by simulataneousequation:

consider   coffee mug 'x' and key chain 'y'

there are total 21 items,

x+y = 21

=> x  = 21 - y .........................(i)

and

total cost is $132.50

8.5x + 2.75y = 132.5 .........(ii)

put value of x from eqn (i) into (ii):

8.5 ( 21 -y) + 2.75y = 132.50

=> 178.5 - 8.5y + 2.75y = 132.50

=> -5.75y = -46

 =>y = 8

Put vaklue of y back in (i):

x = 21 - y

=> x = 21 - 8 = 13

thus, x = 13

he bought 13 coffee mugs and 8 key chains.

The expression for when you translate the graph of y=|2x|−1 is y= |2x-2|-1.

Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. A function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

We are given that;

y = |2x|−1

Now,

To write the expression for when you translate the graph of y = |2x| - 1, we need to use the rules for vertical and horizontal shifts. The rules are:

To shift the graph up or down by k units, add or subtract k to the original function.

To shift the graph left or right by h units, add or subtract h to the input variable.

Using these rules, we can write the expressions for each translation as follows:

a) One unit up: y = |2x| - 1 + 1 y = |2x|

b) One unit down: y = |2x| - 1 - 1 y = |2x| - 2

c) One unit to the left: y = |2(x + 1)| - 1 y = |2x + 2| - 1

d) One unit to the right: y = |2(x - 1)| - 1 y = |2x - 2| - 1

Therefore, by the expression the answer will be y = |2x - 2| - 1.

Step-by-step explanation:

18.50 x 24 = 444, which is not enough, so then you’d have to add another 18.50 which would make it 462.5, which is ok if it goes over the number (450).

Step-by-step explanation:

Each mile is 5280 feet long.

Answer: I believe it would be 0.

Step-by-step explanation:

The median is 97.

Using the stem-and-leaf plot in the diagram, below, write out each data points given, which are:

68, 70, 80, 86, 88, 88, 96, 96, 97, 97, 98, 98, 99, 100, 100, 100, 100, 100

The line plot for these data would have the following frequency for each data point:

68 - 1 dot

70 - 1 dot

80 - 1 dot

86 1 dot

88 - 2 dots

96 - 2 dots

97 - 2 dots

98 - 2 dots

99 - 1 dot

100 - 5 dots

Range = 100 - 68 = 32

Median = 97

Therefore, the median is 97.

Answer:

138.16ft²

Step-by-step explanation:

Oh boy, this is a long one so hang onto your hats:

We're going to start by finding the area of the smaller circle (or pool) the formula for the area of a circle is pi x radius² and we're given the diameter, here's what we're gonna do:

take the diameter and divide it by 2:

20 ÷ 2 = 10

So now we have the radius and all we have to do is plug that into the formula:

10² = 100

(we're doing 3.14 for pi)

3.14 x 100 = 314

So the area of the smaller circle is 314ft²

Now we gotta do the bigger circle, and since we already have a radius, we can skip a step:

12² = 144

3.14 x 144 = 452.16‬

So the area of the bigger circle is 425.16ft²

But now we have to find the difference between the two areas:

425.16 - 314 = 138.16‬

So the larger pool occupies 138.16 more ft² than the smaller pool

Answer: There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.

Two independent variables that could result in a change in the monthly electricity bill are: Physical size of products and Skill level of operators of machines.

Independent variables are the determining factors that influence how a dependent variable changes.
