Step-by-step explanation:

Consider the figure as 3 parts: semicircle with radius of 4 in, rectangle with 7x9 in and rectangle 6x14 in.

Area of semicircle:

A = 1/2*πr² = 1/2*3..14*4² = 25.12 in²

Area of rectangles:

7*9 = 63 in²6*14 = 84 in²

Total area:

Why can’t we just count the boxes to find the area of the circle?

The area of a circle is almost always a decimal - it's hard to fit squares inside a round shape! We can't count the squares to find the area of a circle, we need to use a formula instead.

Put these numbers in order, from least to greatest. If you get stuck, consider using the number line. with a picture

Answers

Answer:

Step-by-step explanation:

When we proceed from left to right on a number line, numbers get bigger.

That means (-5) on the given number is the least and 5 is the greatest.

By this rule, order of the numbers will be,

-4.2, -3.5, -2.1, -1.5, -1, -0.5, 0.5, 3.5, 4.8

Now we can place these numbers on the number line as shown.

Trinity and Peyton were collecting box tops for their class. Trinity collected 36 box tops. Peyton collected
1 ½ times as many. How many cans did they collect all together?

Answers

Note: We need to find the number of total box tops instated of total number of cans.

Given:

Trinity collected 36 box tops.

Peyton collected [tex]1\dfrac{1}{2}[/tex] times as many as Trinity.

To find:

The number of box tops they did collect all together.

Solution:

It is given that,

Number of box tops collected by Trinity = 36

Number of box tops collected by Peyton = [tex]1\dfrac{1}{2}\times 36[/tex]

                                                                    = [tex]\dfrac{3}{2}\times 36[/tex]

                                                                    = [tex]54[/tex]

Total = [tex]36+54[/tex]

        = [tex]90[/tex]

Therefore, the total number of box tops collect all together is 90.

slope: 1/2

y-int: 1

y=1/2x+1

Answer:

Slope=1/2, y-intercept=(0,1)

Step-by-step explanation:

Slope is written in the format of Y/X. If you look at the pattern, you'll notice that every time Y goes up 1, X goes up 2.

So, 1/2.

The y-intercept is where the line crosses the y-axis and is therefore when X is equal to 0. Following the pattern, this would be when Y is equal to 1.

C. 33 + ℓ ≥ 776; ℓ ≥ 743; A ≥ 33(743)


D. 2(33) + 2ℓ ≥ 776; ℓ ≥ 355; A ≥ 33(355)

Answers

Answer:

D. 2(33) + 2ℓ ≥ 776; ℓ ≥ 355; A ≥ 33(355)

Step-by-step explanation:

Answer:

Width of the rectangle is given to be 33 centimeters

Let the Length of the rectangle be x centimeters

So, Perimeter of rectangle is given by formula : Perimeter = 2 × (Length + Width)

⇒ Perimeter = 2 × (x + 33)

⇒ Perimeter = 2x + 66

Now, The perimeter of the rectangle is at least 776 centimeters

⇒ Perimeter > 2x + 66

⇒ 776 > 2x + 66

⇒ 2x < 710

⇒ x < 355

So, The length of the rectangle must be less than 355 cm

⇒ Area of the rectangle < 355 × 33

⇒ Area of the rectangle < 11715 cm²

plz help and pls dont give me no website pls

Answers

Answer:

x=7

Step-by-step explanation:

In a parallelogram, you know that parallel sides are equal in length, therefore, x+4 must equal 5x-24.  From there you solve for x.

x+4 = 5x-24

28 = 4x  (subtract x from both sides and add 24 to both sides)

7=x   (28 divided by 4 is 7).

Answer:

Here you go, please mark brainliest for my effort! Thanks!

Step-by-step explanation:

5x - 24 and x + 4 are equal in length, so set them equal to each other.

5x - 24 = x + 4

Subtract x on both sides.

4x - 24 = 4

Now, add 24 to both sides.

4x = 28

Finally, divide both sides by 4.

x = 7

So the answer is x = 7
