Answer: 2(4)+2b=30  /missing lenght=11

Step-by-step explanation: We know the equation of a rectangle is 2a+2b=perimeter    "a" and "b" both represent a side length

2(4)+2b=30         <--- Plug in the know side lenght

8+2b=30            

8(-8)+2b=30(-8)  <--- Subtract "8" from both sides to further solve

2b=22

2b/2=22/2          <--- Divide each side by "2"

b=11

Answer:

75

Step-by-step explanation:

Since the ratio between flamingos and chachalacas is 2:1, we see that the ratio of flamingos to chachalacas to parrots to herons is 10:5:7:3. The sum of these numbers is 25, so every 'ratio number' gets 375/25 = 15 animals. So the number of chachalacas is 15 * 5 = 75.

Answer: 1/3

Step-by-step explanation:

From the question, we are informed that Pranav ate pizza for dinner on Monday night and had 2/3 of the pizza left over. We are further told that on Tuesday night, he ate 1/2 of what was left.

The amount of pizza that Pranav ate on Tuesday will be:

= 1/2 × 2/3

= 1/3

She ate 1/3 on Tuesday

Answer:

x = 1

Step-by-step explanation:

Since the triangles are congruent then AB ≡ DE , that is

DE = AB

5x - 4 = 2x - 1 ( subtract 2x from both sides )

3x - 4 = - 1 ( add 4 to both sides )

3x = 3 ( divide both sides by 3 )

x = 1

Answer:

m∠2=35°, m∠1=35°

Step-by-step explanation:

∠2 and ∠4 equal 180° when added, so 180-145=35

all angles of a triangle equal 180°, so 180-∠3-∠2=∠1

180-110-35= 35

Answer:

Price of child ticket: 17.

Price of adult ticket: 23

Step-by-step explanation:

25 times 17 equals 425.

1,115 minus 425 equals 690.

690 divided by 30 is 23.

425 plus the 2 adult tickets (23 plus 23 which is 46) would be 471, therefore 17 per child ticket and 23 per adult.

Surface area of a prism is just the sum total of each individual shape's area.

SA = [(3 * 4) + (3 * 3) + (3 * 5) + (1/2 * 3 * 4) + (1/2 * 3 * 4)] cm^2

((Area of rectangle/square is base times height.

Area of triangle is one-half times base times height.))

Answer:

Depends on what numbers are there.

Step-by-step explanation:

If the numbers are 0-10 then there is a 50% chance of the spinner stopping on an even number because there is 5 even numbers and 5 uneven numbers.

The probability of the spinner stopping on an even number will be equal to 5/10.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

The total number on the spinner is 10

The total even number on the spinner is 5.

Probability = 5/10

Therefore, The probability of the spinner stopping on an even number = 5/10

Answer:

1024

Step-by-step explanation:

yeah it's 1024 lol

Answer:

4^5 = 1024

Step-by-step explanation:

Write down the # on the left (4) by the # of times on the left (5)

So it would be: 4x4x4x4x4 = ?

You can cut this problem into pieces.

1. 4x4 = 16

2. 4x4 = 16      

3. 16x16 = 256 (use standard multiplication method)

4. 256 x 4 = 1024

I hope this helps:)

Yes, the triangles are similar to each other by AA rule and EF = 8.

When two triangles have congruent corresponding angles and corresponding sides in equal ratio, then they are said to be similar.

Given are the triangles, Δ ABC and Δ DEF,

In Δ ABC,

∠A + ∠B + ∠C = 180°

∠B = 180°- (60°+20°)

∠B = 100°

In Δ DEF,

∠D + ∠E + ∠F = 180°

∠F = 180° - (60°+100°)

∠F = 20°

∠A ≅ ∠D

∠B ≅ ∠E

∠C ≅ ∠F

We see, all the corresponding angles are congruent.

Therefore, according to definition of similar triangles Δ ABC ~ Δ DEF,

And,

AB/DE = BC/EF = AC/DF = 3/4

BC/EF = 3/4

6/EF = 3/4

EF = 8

Hence, the triangles are similar to each other by AA rule and EF = 8.
