How do I solve this problem for 7th grade!

Answers

Its 55

35% = 35/100
So 35/100*200 <- 200 is the number of all tags
When you do this, you’ll get 70
So 70 tags are blue

Next, to find how many yellow tags, just
3/8*200 = 75
There’s 75 yellow tags

If you add both amounts (70+75) you’ll get 145

Now we know there are 200 tags and 145 of them are yellow and blue, so the rest are red
200-145 =55

Answer:

55 name tags are red

Each figure below is made up of congruent
trapezoids. Find the area of the figure.

Answers

Answer:

12 [tex]c[/tex][tex]m^2[/tex]

Step-by-step explanation:

The formula to find the area of a trapezoid is A = h. We replace the "a" and "b" with 6cm. We then replace the "h" with 12cm as your height is 12cm. The new formula is A = h = x 12. The answer to that equation is 12cm.

Step-by-step explanation:

The store gave her back the difference (20%-15%= 5%)

5%= the $17 returned

100/5= 20

20*17= $340 which was the original price of the TV before discounts

the original price of the tv would be $340

Marcos can seal 5 envelopes every minute. Jerry can seal 7 envelopes every minute. They both seal envelopes for 1 hour nonstop.

How many more envelopes does Jerry seal than Marcos? Show your work.

Answer:

Answers

Answer:

120

Step-by-step explanation:

Since,

Marcos seal 5 envelopes every minutes

Jerry seal 7 envelopes every minutes

Both seal envelopes for 1 hour

Knowing that 1 hour = 60 minutes

Thus,

Marcos = 5 × 60 = 300

Jerry = 7 × 60 = 420

Now subtract

420 - 300 = 120

Hence, Jerry seal 120 more than Marcos.

~Lenvy~

Answer:

120 more envelopes

Step-by-step explanation:

Given the following:

⇒ Marcos can seal 5 envelopes every minute.

⇒ Jerry can seal 7 envelopes every minute.

⇒ They both seal envelopes for 1 hour nonstop.

Question to Answer:

How many more envelopes does Jerry seal more than Marcos?

Solution:

Note that: 1 Hour = 60 Minutes

Thus, we can multiply envelopes by 60 minutes

Marcos → 5 × 60 = 300

Jerry → 7 × 60 = 420

Now we have to subtract to see how many more envelopes does jerry seal more than marcos.

420 - 300 = 120

Base on the result, we can conclude that jerry seal 120 more than marcos.

Three semicircles are placed in a rectangle, as shown below. The length of the rectangle is 72m. Find the area of the shaded region. Use the value 3.14 for pi , and do not round your answer. Be sure to include the correct unit in your answer.

Answers

Step-by-step explanation:

Width of rectangle = 7 cm

because ∵ width of rectangle is equal to the radius of each semicircle.

therefore ∴ radius of each semicircle (r) = 7 cm.

therefore ∴ Diameter of each semicircle = 14 cm

therefore ∴ Length of rectangle = 3 x 14 = 42 cm.

Answer:

63.21cm'2

Please! Mark me as brainliest please.

Your answer is 1049.76

72 divided by 3= 24, 24 is your diameter of each semi circle

To find the area of your semi circles you’ll use pi times radius squared.

Aka 3.14 times 12^2 divided by 2 = 226.08

Times 3 for 3 semi circles

226.08 times 3= 678.24

Now find the area of the rectangle and you get the height from the semi circles which is 24m

72 times 24= 1,728m^2

Now you take the area of the rectangle and subtract the area of the circles

1,728 - 678.24 = 1,049.76m

Explain how to find the volume of a cube that has edge length 1/4 yd. Then, find the volume of the cube.
Answer in complete sentences, include all relevant formulas and calculations, and be sure to include appropriate units.

Answers

Answer:

1/64 cubic yards or 0.015625 cubic yards

Step-by-step explanation:

A cube has equal edge lengths.

To find the volume of a cube using edge length, simplify raise the value of the edge length to the 3rd power or cube it.

⇒ V = (edge length)³

Using this formula and keeping in mind the edge length is 1/4 yd, substitute it in the formula.

V = (1/4)³V = 1/64 [4³ = 64]V = 1/64 cubic yards or 0.015625 cubic yards

Answer:

Volume of the cube is 1/64 yd³.

Step-by-step explanation:

Given that, Length of each edge of the cube is 1/4 yard.

Using formula:

[tex] \: \: \dashrightarrow \: \: { \underline{ \boxed{ \pmb { \sf{ \purple{Volume _{(cube)} = (edge) ^{3} }}}}}} \\ [/tex]

On substituting the value of edge in the above formula, we will get the required volume of the cube.

[tex] \: \: \dashrightarrow \: \: \rm Volume = \bigg( \dfrac{1}{4} \bigg) ^{3} \\ [/tex]

[tex]\: \: \dashrightarrow \: \: \rm Volume = \dfrac{1}{4} \times \dfrac{1}{4} \times \dfrac{1}{4} \\ [/tex]

[tex]\: \: \dashrightarrow \: \: { \underline{\boxed{ \purple{\pmb{ \sf {Volume = \dfrac{1}{64} \: {yd}^{3} }}}}}} \\ \\ [/tex]

Hence,

Volume of the cube is 1/64 yd³
