ANSWER THIS AND ILL MAKE YOU BRAINLY!!

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.

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]

Answer:

angle 1 and angle 2 are supplementary angles

Step-by-step explanation:

When the base of the angles forms a straight line, the sum of the angles is 180°. That's the definition of supplementary angles.

Complementary angles form a right angle. The sum of complementary angles is 90°

A slightly silly way to remember Complementary angles: The two angles look at each other and compliment each other saying, "You look all right to me!"

"Yes, we are so right together!"

Answer:

D) $115

Step-by-step explanation:

15x + 40 = y

15 (5) + 40 = 115

15 x 5 = 75

75 + 40 = 115

Answer:

D is the answer

Step-by-step explanation:

15x5=75

75+40=115

Answer:

Distance B = 1275 kilometers.

Step-by-step explanation:

Let the two distances and time be A and B respectively.

Given the following data;

Distance A = 17 kilometers.

Time A = 8 minutes.

Distance B =?

Time B = 60 minutes.

First of all, we would find the constant speed;

Speed = distance/time

Substituting into the equation, we have;

Speed = 17/8

Speed = 2.125 km/m

Now, to find the distance B;

Distance B = speed * time

Distance B = 2.125 * 60

Distance B = 1275 km

Answer:

4/40

Step-by-step explanation:

you can reduce this to 1/10

multiplying 4 by both 1 and 10 will give you the fraction 4/40 both can be divided by 4 and that's how it can reduce to the 1st fraction (1/10)

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:

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

=

2

3

cups light orange

ounces red paint

so

For z=3 cups

substitute and solve for x

\frac{x}{3}=\frac{3}{2}

3

x

=

2

3

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
