Find the area of the shape shown below.

Answers

Answer: 10

Step-by-step explanation:

To work out the area of this shape you have to split this into 1 square and 2 triangles.

The formula of the area of the triangle is base x height divided by 2

The first triangle on the left would be 2x2/2=2

The area of second triangle on the left is 4x2/2=4

The formula for the square is base x height.

Then to work out the area of the square you do 2x2=4

So, to work out the area of the whole shape you add all of the areas together.

2+4+4=10

Destiny bought a carton of orange juice. She drank 1/3 of the carton on Monday and 5/12 of the carton on Tuesday. What fraction of the carton did Destiny drink?

Now you can add the fractions.

5/12 + 4/12

= 9/12 Carton

Answer:

[tex](x,y) =(-4,-3)[/tex] --- Vertex

[tex]x = -4[/tex] --- Axis of symmetry

Step-by-step explanation:

Given

[tex]y = -6(x + 4)^2 - 3[/tex]

Solving (a): The vertex

For an equation written in

[tex]y = a(x - h)^2 + k[/tex]

The vertex is:

[tex](x,y) = (h,k)[/tex]

By comparison:

[tex]y = a(x - h)^2 + k[/tex] and [tex]y = -6(x + 4)^2 - 3[/tex]

[tex]-h =4[/tex] [tex]k = -3[/tex]

[tex]h =-4[/tex] [tex]k = -3[/tex]

So, the vertex is:

[tex](x,y) =(-4,-3)[/tex]

Solving (b): The axis of symmetry

For an equation written in

[tex]y = a(x - h)^2 + k[/tex]

The axis of symmetry is:

x = h

In (a):

[tex]h =-4[/tex]

So:

[tex]x = -4[/tex]

Solve -a + 7 = 2a - 8. a=5 D a= 15 a -3 = B a

Answers

We want to solve for a
-a + 7 = 2a - 8
we will add 8 to both sides and simply to
-a + 15 = 2a
We will then add a to both sides and simply to
15 = 3a
We then divide by 3 on both sides to get
a=5

7 Romeo and Juliet first saw each other when they were 270 feet apart.
Romeo began running toward Juliet at a rate of 16 ft/s. At the same
moment, Juliet began running toward Romeo at a rate of 14 ft/s.
A. How many seconds after they started running will they meet?
B. How far will Romeo have run then?

Answers

Answer:

A: 9 seconds

B: 144 ft.

Step-by-step explanation:

Let t = no. of seconds for them to meet

When they meet the sum of their distances is 270 ft, dist = rate * time

16t + 14t = 270

30t = 270

t = 270/30

t = 9 seconds

He ran 9 sec at 16 ft/sec, therefore:

9 * 16 = 144 ft

A: 9

B: 144

Violet made cookies for the bake sale. 7/10 of the cookies are chocolate chip. 3/4 of the remaining cookies are sugar. What fraction of cookies are sugar cookies?

Answers

We know that 7/10 of the cookies are chocolate chip, so that means there are 3/10 of the cookies left.
We now want to find what 3/4 of 3/10 is.
We can do this by multiplying both fractions
3/4x3/10 (we just multiply across) to get 9/40.
We cannot simplify this answer, so our final answer is 9/40 of the cookies are sugar cookies.

The measure of angle ABC is 140°.

What is an angle bisector?

The angle bisector in geometry is the ray, line, or segment which divides a given angle into two equal parts.

Angle bisector BD is bisecting angle ABC equally, which is

∠ABC=∠ABD+∠DBC

⇒ 140°=∠DBC+∠DBC

⇒ 2∠DBC=140°

⇒ ∠DBC=70°

Therefore, the measure of angle DBC from the given figure is 70°.

Step-by-step explanation:

Hey there!

the exterior angles of a quadrilateral add up to equal 360

so 360=2x+40+4x+3x+x+50

step 1 combine like terms

2x+4x+3x+x=10x

50+40=90

now we have

360=10x+90

step 2 subtract each side by 90

360-90=270

90-90 cancels out

now we have 270=10x

step 3 divide each side by 10

270/10=27

we're left with

Bean seeds from supplier A have 85% germination rate and those from supplier B have 75% germination rate. A seed-packing company purchases 40% of its seed from A, 60% from B, and mix them together. Find the probability that a seed selected at random from the mixed will germinate.

Answers

Answer:

0.79 = 79% probability that a seed selected at random from the mixed will germinate.

Step-by-step explanation:

Probability of a seed germinating:

85% of 40%(from company A)

75% of 60%(from company B)

Then

[tex]P = 0.85*0.4 + 0.75*0.6 = 0.79[/tex]

0.79 = 79% probability that a seed selected at random from the mixed will germinate.
