Answer:

1.) Triangle ABC is congruent to triangle DCB

Step-by-step explanation:

For the first one, the first 3 steps proved that all 3 sides in the 2 triangles formed by the diagonal are congruent to each other, meaning triangle ABC is congruent to triangle DCB (I named it like that specifically because the way you name the triangles has to be the exact same way you named the other triangle).

For the second one, the congruency statement should be GL ≅ AD, because the HL congruence theorem states that if a hypotenuse and leg of one right triangle is congruent to the hypotenuse and leg of another right triangle, those triangles are congruent.

Answer:

choice 4) Triangle ABC is congruent to triangle DCB because of the Side-Side-Side theorem

Answer:

49,000 square cm

Step-by-step explanation:

To get the area of the dilated rectangle, we need the dilated dimensions

We simply multiply the scale factor by the dimensions

we have this as;

3.5 * 50 = 175 cm

and

3.5 * 80 = 280 cm

The area of the dilated rectangle is thus;

280 * 175 = 49,000 cm^2

Answer: 14 2/5 books per year

Step-by-step explanation:

From the question, we are informed that a middle school student reads 48 books in 31/3 years. The students reading rate in books per year will be calculated as:

= Total books read / Number of years

= 48 ÷ 3 1/3

= 48 ÷ 10/3

= 48 × 3/10

= 144/10

= 14 2/5 books per year

Answer:

  see below

Step-by-step explanation:

The applicable properties of exponents are ...

  (a^b)^c = a^(bc)

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

That is, since the outside exponent is even, the sign is immaterial. This is also true for the other expression containing -2. The result is positive.

y subtracted from 10 is

10 - y

Hope it will help :)

Answer: D: 10 - y

Step-by-step explanation:

we can rule out option B and C since there isn't a subtraction sign

so now we have A and D

The answer isn't A because thats 10 being subtracted from y

Answer:

w=[tex]\frac{40}{3}[/tex]

Step-by-step explanation:

2(2w+8)+2w=96

Distribute the 2.

4w+16+2w=96

Combine like terms.

6w+16=96

Subtract 16

6w=80

Divide 80 by 6.

w= 13.333333 or [tex]\frac{40}{3}[/tex]

Answer:

2

Step-by-step explanation:

Brainliest?!?!?!?

The answer to this would be 2.

Step by Step Explanation

Equation: 11x+2=24

Variable for the missing number: x

To do this, I suggest writing out an equation with the variable X to represent the missing number that we are trying to find. The equation would look something like this: 11x+2=24.

From here, to solve the equation, subtract 2 from both sides, which would then get the equation to be 11x=22. From here, you would then divide both sides by 11 to get the variable on it's own, which would be x=2. Since x is the variable that we are using to represent the missing number, the missing number would be 2.

Answer:

x = 84

Step-by-step explanation:

The sum of the angles around a point = 360°

sum the given angles and equate to 360

x + 132 + 54 + 90 = 360

x + 276 = 360 ( subtract 276 from both sides )

x = 84

Answer:

x = 84°

Step-by-step explanation:

→ Recall the fact that angles around a point add up to 360°

360 - (90 + 54 + 132 ) = x

→ Simplify

360 - 276 = x

→ Simplify again

84 = x ∴ x = 84°

BODMAS rule

Step-by-step explanation:

There are four basic rules in mathematics, Addition, subtraction, Multiplication and Division. All these operations can be used together or separately depending on the problem. When all the operation are required in the problem then BODMAS rule is applied to simplify the problem. BODMAS rule determines that operation will be performed according to the rule : Division, Multiplication, Addition and Subtraction. First operation which will be performed is division and last will be subtraction. This rule is same for all types of problems.

Hi there!

Step By Step:

We know that 215 pounds are about 215 strawberries since every strawberry are about 1 pound.

Let think about this... 215 pounds are 215 strawberries.

If his brother ate 56 of the strawberries, it means that his brother ate 56 pounds of the strawberry.

We can also think like this... 56/215

Final Result: 56 pound sof strawberries.
