Answer:
Choice #1) 4.7 cm
Step-by-step explanation:
circumference of full circle = 2(r)(3.14)
a full circle would be = 2(3)(3.14) = 18.84 cm
It is 1/4 circle so 18.84/4=4.7 cm
Answer:
10.7
Step-by-step explanation:
1. I first grabbed a ruler to measure the other straight side of the figure.
2. Both of the straight sides were 3 cm so I knew that the answer had to be greater than 6 cm.
3. I then estimated that the other side was longer than the 3 cm.
4. I then had to my logic to figure out the answer and I very quickly realized that 4.7 cm would not make since because that is less than 6 cm. I know 7.7 cm would not make since because I knew the curved side was longer than 3 cm not shorter. 18.8 cm did not make since because that answer has WAY to much cm. Using the process of elimination, 10.7 cm was the only answer that made since.

Arnie is mixing red and yellow paints to make two different shades of orange. To make 1 cup of dark orange paint, he needs 7 ounces of red paint and 1 ounce of yellow paint. To make 2 cups of light orange paint, he needs 13 ounces of yellow paint and 3 ounces of red paint. Answer parts a and b.
Answer:
Arnie has enough red paint
Step-by-step explanation:
step 1
Find out the number of ounces of red paint needed to make 3 cups of dark orange paint
Let
x -----> number of ounces of red paint
y -----> number of ounces of yellow paint
z ----> cups of dark orange
we know that
\frac{x}{z}=\frac{7}{1}\ \frac{ounces\ red\ paint}{cups\ dark\ orange}
z
x
=
1
7
cups dark orange
ounces red paint
so
For z=3 cups
substitute and solve for x
\frac{x}{3}=\frac{7}{1}
3
x
=
1
7
x=21\ ounces\ of\ red\ paintx=21 ounces of red paint
step 2
Find out the number of ounces of red paint needed to make 3 cups of light orange paint
Let
x -----> number of ounces of red paint
y -----> number of ounces of yellow paint
z ----> cups of light orange
we know that
\frac{x}{z}=\frac{3}{2}\ \frac{ounces\ red\ paint}{cups\ light\ orange}
z
x
=

3
cups light orange
ounces red paint
so
For z=3 cups
substitute and solve for x
\frac{x}{3}=\frac{3}{2}

x
=

x=4.5\ ounces\ of\ red\ paintx=4.5 ounces of red paint
step 3
Adds the ounces of red paint
21+4.5=25.5\ ounces\ of\ red\ paint21+4.5=25.5 ounces of red paint
25.5\ ounces < 32\ ounces25.5 ounces<32 ounces
therefore
Arnie has enough red paint

Find the inverse of f(x) = √x-1
Answer:
Step-by-step explanation:
For a function to have an inverse, it has to pass the horizontal and vertical line test, yes both of them. This function does, so we can continue. The first step for finding an inverse is replacing f(x) with y. Then switch the places of x and y.
[tex]x=\sqrt{y-1}[/tex]
Now the next step is to solve for this new y value, which is equivalent to f^-1(x). Square both sides to get rid of the radical.
[tex]x^2=y-1[/tex]
Add 1 to both sides and that is your inverse function
[tex]y=x^2+1[/tex]

For the following statements 11 - 16 write TRUE or FALSE.
11. Through any two points there is exactly two lines.
12. A line contains of at LEAST two points.
13. A plane contains at least three non-collinear points.
14. Two lines intersect at a point.
15. Two planes intersect at a point.
16. A line and a plane intersect at a line.
Answer:11 is false. Through any two points there is exactly one line. 12 is true. 13 is true. 14 is true. 15 is false. Two planes intersect at a line. 16 is false. A line and a plane would intersect at a point

What’s the value of a?
Answer:
a = 69
Step-by-step explanation:
The linear pair equals 180 degrees.
a + 90 + 21 = 180
a + 111 = 180
a = 69
nice!
Answer:
A= 69 degrees
Step-by-step explanation:
if all those angles equal a total of 180 degrees then all you need to do is add the angles your given which in this case is 21 and a 90 degree angle which would equal 111 degrees, then subtract 111 from 180 and that would be the answer to the missing angle, which is 69 degrees.
21 + 90 = 111
180- 111 = 69
Solve for x
A. 10
B. -8
C. 6
D. 3
Answer:
c (6)
Step-by-step explanation:
by the corresponding angles postulate, the angle above 20x-5 will be 65°.
20x - 5 + 65 = 180 they are supplementary angles (angles that add up to 180°)
20x + 60 = 180
20x = 120
x = 6

Answer:
60 milligrams
Step-by-step explanation:
just cross multiply! percentages are just fractions of 100. so you can say that [tex]\frac{45}{x} =\frac{75}{100}[/tex]
multiple 75 by x and 45 by 100 and you get
4500=75x
divide both sides by 75 and you get 60
