Mia is making costumes for a play. Each costume needs 3 7/9 yards of fabric. If Mia is making 6 costumes, how much fabric does s

mihalych1998 [28]

If she is making 6 costumes that need 3 7/9 yards each, the equation would be 6 x 3 7/9.

The answer to that equation would be 22 2/3.

How to get the answer:
3 x 6 = 18
7 x 6 = 42 (the seven is from the 7/9)
42/9 = 4 2/3

then add the eight teen and the 4 2/3 and you get 22 2/3.

Answer:

$84\text{ in}^2$ .

Step-by-step explanation:

We have been given that Mrs. Chen's students are making and decorating gift boxes for a nursing home. The boxes are 7 inches wide, 7 inches long, and 7 inches high. We are asked to find the amount of cardboard that is needed for each box.

We will use surface area of cuboid formula to solve our given problem.

$SA=2(lw+lh+hw)$ , where,

l = Length,

w = Width,

h = Height

$SA=2(7\text{ in}\cdot7\text{ in} +7\text{ in}\cdot7\text{ in}+7\text{ in}\cdot7\text{ in})$

$SA=2(14\text{ in}^2+14\text{ in}^2+14\text{ in}^2)$

$SA=2(42\text{ in}^2)$

$SA=84\text{ in}^2$

Therefore, Mrs Chen needs 84 square inches of cardboard.

What is as 8 hundred is 8 thousand

Irina-Kira [14]

Not quite understand the question. We assume that the issue of ratios of numbers of 800 and 8000.
Then 800 is one-tenth of the 8,000 800 other words is 10% of 8000.
Conversely, 8000 it ten times at 800 and 1000% of 800.

Given:

triangular garden with base 7 ft and area 28 ft^2

Find:

height of the triangle

Solution:

The formula for the area of a triangle is ...

A = 1/2bh . . . . . where A is the area, b is the base length, and h is the height

Multiplying by 2/b, we can get a formula for the height. Using this formula, we can solve the problem.

h = 2A/b

We can let h represent the height, and fill in the given data.

h = 2(28 ft^2)/(7 ft)

h = 8 ft

The height of the triangle is 8 feet.

Given:

(0, 110), (5, 345) . . . . . where the points represent ...

(years after 2010, students using the hotline)

Find:

a linear model for the data

the number of students predicted for 2019

Solution:

The 2-point form of the equation for a line is ...

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

where the points are (x1, y1) and (x2, y2). Using the given points, our linear model is ...

y = (345 -110)/(5 -0)(x -0) +110

y = 47x +110 . . . . the linear model, where ...

y is the number of students using the hotline

x is the number of years after 2010

__

In 2019, x = 9, so y = ...

y = 47(9) +110 = 423 +110 = 533

The number of students predicted to use the hotline in 2019 is 533.
