Which statement is sometimes true:

1. A square is a rhombus
2. A trapezoid is a parallelgram
3. A rectangle is a parallelogram
4. A rectangle is a square

Answers

Answer 1

Answer:

4. A rectangle is a square

Step-by-step explanation:

A rectangle can be a square, but not always. A rectangle has 2 pairs of parallel sides, 2 pairs of congruent sides, and 4 right angles. Squares have 2 pairs of parallel sides, 4 congruent sides, and 4 right angles. So, the difference between the two is that adjacent sides are not necessarily congruent in rectangles, but they are in squares. This means that some rectangles can be a square. If a rectangle has all congruent sides, then it is a square. On the other hand, some rectangles do not have all congruent sides, and thus are not squares.

Answer:

2nd number line represents √7 best

Step-by-step explanation:

Method 1

√7 ≈ 2.65

Therefore, the 2nd number line represents √7 best

(the one with the dot between 2 and 3)

Method 2

√1 = 1

√4 = 2

√9 = 3

Therefore, as √7 is between √4 and √9, the solution is somewhere between 2 and 3.

Alexandra is following a recipe that requires three fourths cup of water. She needs to make 10 servings. How many cups of water does Alexandra need?

one and one fifth cups
three and one fourth cups
seven and two fourths cups
eight and two thirds cups

Answers

So if one batch needs 3/4 of a cup and she needs to make 10 batches then you multiply how many batches by how many water cups required for one batch:

3/4 • 10 = 30/4 = 7 2/4

So she needs seven and two fourths cups of water.

Answer:

3/4 • 10 = 30/4 = 7 2/4

Answers

Answer:

if m∠1 = 30° then m∠3 = 30° as they are parallel to each other and that is why they will have same angles.

therefore m∠3 = 30°

extra's:

→ m∠2 = m∠4 =

→ (360-30*20)/2

→ 150°

...............................

See here

m<1 and m<3 are opposite angles to eachother.

And we know that opposite angles are equal

so

m<1=m<3 m<3=30°

The value of the given expression is -15 - 3y

What is the value of the expression?

In maths, when there are terms in the bracket, it means we are to multiply the terms in the brackets by each other. This means that 5 + y would be multiplied by -3.

Multiplication is the process of determining the product of a set of numbers.

(5 + y)(–3) = -15 - 3y

What is a cuboid?

A cuboid is a three-dimensional closed figure which has volume along with surface area.

The volume of a cuboid is the product of its length, width, and height.

The total surface area of a cuboid is 2(lw + wh + wl) and the lateral surface area is 2(l + w)×h.

Given, A box that has a volume of 729 inches.

First we'll prime factorize 729.

729 = 3×243 = 3×3×81 = 3×3×3×3×3×3.

If we take the cube root of 729 it would be 3×3 = 9.

So, It is a cube with a side length 9.

Now, We know area of a cube is side².

Therefore, The area of this cube is 9² = 81 in².

Randy was paid $50 for his first night in the restaurant where he works as a cashier. he worked the rest of the week for $6.50 per hour. the equation, y = 6.50x + 50, represents the amount he made that week. What are the ordered pairs for the equation when you use these x-values: 10 and 20

Answers

Step-by-step explanation:

so, we first put 10 in for x :

y = 6.50×10 + 50 = 65 + 50 = $115

and then we put 20 in for x :

y = 6.50×20 + 50 = 130 + 50 = $180

so, the ordered pairs are

(10, 115) and (20, 180)

Answer:

81 cm²

Step-by-step explanation:

Start by finding the perimeter of a rectangle.

[tex]Perimeter = 2(l+w)[/tex]

Plug in the given values into the equation:

[tex]Perimeter=2(14+4)=2(18)=36\ cm[/tex]

Since the perimeter of a square is:

[tex]Perimeter = 4s[/tex]

We can plug 36 cm in for the perimeter to solve for s

[tex]36\ cm=4s[/tex]

Divide both sides by 4

[tex]s=9\ cm[/tex]

The area of a square is:

[tex]Area=s^2[/tex]

Plug in the 9 cm for s

[tex]Area=9^2=81 \ cm^2[/tex]

How many solutions exist for the given equation?3x + 13 = 3(x + 6) + 1

Answers

Answer:

0

Step-by-step explanation:

3x+13=3(x+6)+1
Expand:

3x+13=3x+18+1
Simplify:

3x+13=3x+19
Subtract 13 from both sides:
3x+13-13=3x+19-13
Simplify:

3x=3x+6

Subtract 3x from both sides:
3x-3x=3x-3x+6

0=6

Since the sides are not equal there are no solutions to this problem
