Answer:

Answer choice D:

The congruent figures are A and D

Congruent means: Exactly equal in size and shape. Matching sides or pieces/parts have the same length. Matching angles have the same measure. For any set of matching geometric figures, corresponding sides, angles, faces, etc. are matching.

Therefore A and D are the congruent triangles!

Answer:

64 mL

Step-by-step explanation:

Step 1: Find % of milk in each cup

1600(0.6) = 960 mL in cup A

1600 - 960 = 640 mL in cup B

Step 2: Find % milk drank in each cup

960(0.4) = 384 mL drank from cup A

640(0.7) = 448 mL drank from cup B

Step 3: Find the difference

448 - 384 = 64 mL

Answer: A.) $8000

Step-by-step explanation:

Given the following :

Purchase value = $10,000

Salvage value = $4000

Useful life = 5years

Sum of digit in years = (1 + 2+ 3 + 4 + 5) = 15

Sum of years Depreciation formular is expressed as follows:

(Useful years / sum of years digit) × depreciable amount

Depreciable amount = purchase value - salvage value

Therefore,

Depreciable amount = $10000 - $4000 = $6000

First year Depreciation = (5 / 15) × $6000

= 0.3333333 × $6000 = $1999.99

= $2000

Therefore,

Value after first year equals :

Purchase value - first year Depreciation

$10,000 - $2,000 = $8,000

Answer: x = 15

Step-by-step explanation:

First, we will have to acknowledge that Angle M is a complementary angle (that means that it is 90 degrees) meaning that 2x° + 4x° will equal 90 degrees. So, let’s set up this equation.

90 = 2x + 4x

90 = 6x

[tex]\frac{90}{6}[/tex] = [tex]\frac{6x}{6}[/tex]

15 = x

Therefore, the x is 15.

They are both rational numbers

Step-by-step explanation:

Rational numbers are terminated numbers, meaning that they have a definite end, even in decimal form. An irrational number is infinite; their decimal places go on forever (An example would be π).

Answer:yes

Step-by-step explanation:Any

Number which is in the form of p/q where both p and q are integers and q is not equal to 0 is called a rational number. -1/2 satisfies this hence it is a rational number. 7 can be written as 7/1 which also satisfies this hence it is also a rational number.

This is a 30-60-90 triangle. With this special template, the hypotenuse is always twice as long as the shorter leg. Put another way: the shorter leg is half as long as the hypotenuse. So the shorter leg is 4/2 = 2 units long.

The longer leg is equal to sqrt(3) times the short leg. The long leg is 2*sqrt(3) units long which is the final answer.

[tex]\frac{x}{-5}(-5) =15(-5)[/tex]

[tex]x=-75[/tex]

Answer: x = 75

Explanation: In this problem, notice that x is being divided by -5 so to get x by itself, we need to multiply both sides of the equation by -5.

Notice that on the left side, the -5 and -5 cancel

each other out so we're just left with x.

On the right side, we have (-15)(-5) which is 75.

So x = 75.

Finally, remember that we can check our answer by

plugging a 75 back into the original equation.

Answer:

equation: 4w + 8 = 208

width = 50 ft; length = 54 ft

Step-by-step explanation:

w = width

length = L = width + 4 = w + 4

perimeter = 2(L + w) = 2(w + 4 + w) = 2(2w + 4) = 4w + 8

perimeter = 208 ft

4w + 8 = 208

4w = 200

w = 50

width = 50 ft

length = 50 + 4 = 54

length = 54 ft

Answer:

Equation: yard = 4w+8 = 208

width = 50  length = 54

Step-by-step explanation:

yard = w + w + l + l

Since length = width + 4, replace the lengths with that.

yard = w + w + (w+4) + (w+4)

Simplify the right side.

yard = 4w+8

Replace "yard" with 208 because we know its perimeter is 208.

208 = 4w + 8

Subtract both sides by 8.

200=4w

Divide each side by 4.

50 = w

Conclusion: width = 50.

Since length = width + 4 and width =50, length = 54.

Answer:

304 square meters

Step-by-step explanation:

here is why,

area of a triangle formula is:

A = bh/2, so

12 * 10/ 2 = 60

we multiply this by two (for each triangle face with these dimensions) to get 120. then we do the same for the other two trangular faces.

8 * 11/2 = 44

we multiply by two again to get 88.

finally, for the base

12 * 8 because area of a rectangle formula is:

A = L * W

12 * 8 = 96

we get our final answer by adding everything up to get 96 + 88 + 120 = 304

Answer:

A = 60 cm²

Step-by-step explanation:

Finding BC using Pythagorean Theorem:

=> [tex]c^2= a^2+b^2[/tex]

=> [tex]13^2 = a^2+5^2[/tex]

=> 169-25 = [tex]a^2[/tex]

=> [tex]a^2[/tex] = 144

Taking sqrt on both sides

=> BC = 12

So,

BC = CD = 12

=> BD = BC+CD

=> BD = 12+12

=> BD = 24

Now, The area:

=> Area of a Triangle = [tex]\frac{1}{2} (Base)(Height)[/tex]

Where BASE = 24, HEIGHT = 5

=> A = 1/2(5)(24)

=> A = 1/2(120)

=> A = 60 cm²

Step-by-step explanation IN triangle abc,

AC² = AB² + BC² (Phythogoras theorem)

13² = 5² + BC²

169 - 25 = BC²

144 = BC²

BC² = 144

BC = 12 (APPLAYING SQAURE ROOT)

Then in triangle ADC,

AD² = AC² + CD²

AD² = 13² + 12² (CD = BD - BC)

AD² = 169 + 144

AD = 17cm (aprox.)

Therefore area of triangle abd = 1/2× length × side = 1/2× 5 ×24 = 5 × 12 = 60cm

[tex]2 -green\\4- yellow,\\ 6- brown\\ 3- red pieces\\Probability = Event/Total possible Outcomes \\Event = 4\\Total-possible-outcome = 2+4+6+3 =15\\Probabillty = 4/15\\Probabillty = 0.26666666\\Probability = 0.267[/tex]

The probability of getting a yellow candy is 0.266.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given that, You open a bag of M&M candies to find that it contains 2 green, 4 yellow, 6 brown, and 3 red pieces of candy.

We are asked to find, what is P(yellow)

We know that, Probability(Event) = Favorable Outcomes/Total Outcomes

Favorable Outcomes = number of yellow candies = 4

Total Outcomes = total number of candies = 15

Therefore, p(yellow candy) = 4/15 = 0.266

Hence, the probability of getting a yellow candy is 0.266.

Answer: 1

Step-by-step explanation:

The mean is the average of the sum of all integers in a data set.

Caroline has 2 pieces of cheese, Samuel has 4 pieces of cheese, Abby has 4 pieces of cheese, and Jason has 2 pieces of cheese

2 + 4 + 4 + 2 = 12

12 divides by 4, since there are 4 people, to equal the mean

12 / 4 = 3

Now since we have the mean, find the distance from the mean to each number

3 - 2 = 1

4 - 3 = 1

4 - 3 = 1

3 - 2 = 1

1 + 1 + 1 + 1 = 4

4 / 4 = 1

Answer:

B. ∠DBC

Step-by-step explanation:

∠DBA is an acute angle

∠GFE is also an acute angle

∠MLK is a right angle, neither acute or obtuse (it's in its own category)

Answer:

B. ∠DBC

Step-by-step explanation:

Obtuse angles are angles larger than 90 degrees.

We can easily tell that ∠GFC and ∠MLK aren't obtuse, since ∠GFC is acute and ∠MLK is a right angle. Right angles and acute angles are always less than obtuse.

Now, for a trickier one. Let's look at ∠DBA and ∠DBC

It's easer to find out what type of angles they are by separating them. (look at image)

See? ∠DBA is acute. And we can easily tell that ∠DBC is an obtuse angle.
