Answers

Answer:

BC is 40.8

B° is 59.03°

C° is 30.96°

Step-by-step explanation:

classic pythagoras (a² + b² = c²)

35² + 21² = 1666

sqrt1666 = 40.8

you do tan(x) here because you want to find B° and only know the opposite and adjacent sides.

35/21 = 1.66...

tan-¹(1.66..) = 59.03°

you do tan(x) here because you want to find C° and only know the opposite and adjacent sides.

21/35 = 0.6

tan-¹(0.6) = 30.96°

If 9 is subtracted from two thirds of a number, the result is 7. Find the number
the number is 3
the number is 10,67
the number is 24

Answers

Answer: 24

Step-by-step explanation:

x/2*3-9=7. So you want to know what x is. So lets start reverse thinking. 7+9=16, 16=x/2*3. That means 16 is 2/3 of x. 16/2=8, 8*3=24! The answer is 24.

Answers

Answer:

angle 8= 120 degrees

angle 7= 60 degress

Step-by-step explanation:

So since it's a line, they will equal 180. So since angle 7 is half of 8 we need to a pair of numbers that add to 180. So you can find out that 120/2 is 60. Then 60+120=180

The question is in the image below!!!!

Answers

Step-by-step explanation:

We must realise that the image of the quadratic curve shown is not showing the full curve. Instead it extends further out.

For all quadratic curves, the domain is all x-values.

We see here that this quadratic curve has an absolute minimum at y = -4 and the curve stretches towards positive infinity.

Hence the range is y >= 4.

The correct answers are the 1st and 5th options.

A circle diameter is 11 cm a square has a side length of 7 cm

Answers

Answer:

By the Pythagorean theorem, the diagonal length (d) of the square is

 d² = 7² + 7²

 d = √98 ≈ 9.8995

Since the diameter of the circle (11 cm) is greater than the diagonal length of the square (9.9 cm), you know the square will fit into the circle without touching.

-0.72x + 0.42x = 8.4
solve for x

Answers

You first have have to add -0.72 and 0.42 because they both have like terms. Then you will get -0.3x. Then you will divide both sides by -0.3 because you have to get x alone. When you do that you’ll get -28. That’s your answer -28.

A They are parallel because they have the same slope of −2.
B They are parallel because they have the same slope of one half.
C They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.
D They are lines that lie exactly on top of one another because they have the same slope and a different y-intercept.

Answers

Answer:

C. They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.

Step-by-step explanation:

Given lines

6x + 3y = 12 ⇒ 2x + y = 4 ⇒ y = -2x + 44x + 2y = 8 ⇒ 2x + y = 4 ⇒ y = -2x + 4

The lines are same as both have same slope and y-intercept.

Correct statement is following:

C. They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.

in slope intercept form, what is the equation of the line having a slope of 2 and passing through the point (6,24)?​

Answers

Answer: y = 2x + 12

Explanation: The slope-intercept form is y = mx + b, where m is slope and b is the y-intercept. Substituting 2 for m, 6 for x, and 24 for y, we have 24 = 2(6) + b. Simplifying, we get that b = 12, so the equation is y = 2x + 12.

Answer:

y = 2x + 12

Louise is 56 3 /4 inches tall. Theresa is 1 1 /2 inches shorter than Louise and Jane is 1 1/ 5 inches shorter than Theresa. How tall is Jane?

Answers

Answer: [tex]54\dfrac1{20}\text{ inches}[/tex]

Step-by-step explanation:

Given:  Height of Louise  = [tex]56\dfrac34 \text{ inches }=\dfrac{4\times56+3}{4}=\dfrac{227}{4}\text{ inches}[/tex]

Then , height of Theresa = Height of Louise  [tex]-1\dfrac{1}{2}\text{ inches}[/tex]

[tex]=\dfrac{227}{4}-\dfrac{3}{2}\text{ inches}\\\\=\dfrac{227-6}{4}=\dfrac{221}{4}\text{ inches}[/tex]

Height of jane = height of Theresa - [tex]1\dfrac15[/tex] inches

[tex]=\dfrac{221}{4}-1\dfrac15\text{ inches}\\\\=\dfrac{221}{4}-\dfrac{6}{5}\text{ inches}\\\\=\dfrac{5\times221-6\times4}{20}\text{ inches}\\\\=\dfrac{1105-24}{20}=\dfrac{1081}{20}\text{ inches}\\\\= 54\dfrac1{20}\text{ inches}[/tex]

Hence,  Jane is  [tex]54\dfrac1{20}\text{ inches}[/tex] tall.

A car is traveling at a steady speed. It travels 2 1/2 miles in 3 1/3 minutes. How far will it travel in 41 minutes? In 1 hour

Answers

Answer:

120 miles

Step-by-step explanation:

You multiply 41 times 4 equal 120 miles.

Answer:

30 3/4 miles, 45 miles

Step-by-step explanation:

First we find the unit rate, in miles per minute:

 2 1/2 miles            5/2 mi          1/2 mi         1 mi

--------------------- = --------------- = ------------- = -------------- = 3/4 mile/min

 3 1/3 minutes       10/3 min        2/3 min       4/3 min    

In 41 minutes the car will travel (3/4 mi/min)(41 min) = 123/4 mi = 30 3/4 mi

In 1 hour, or 60 minutes, the car will travel (3/4)(60) mi = 45 mi
