Emily needs enough Fabric for 3 1/2 hats. Since she has half a hat done. If each bag requires 1 2/7 ft of Fabric, how much fabri
kow [346]

first off let's convert the mixed fractions to improper fractions.

\stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}} ~\hfill \stackrel{mixed}{1\frac{2}{7}}\implies \cfrac{1\cdot 7+2}{7}\implies \stackrel{improper}{\cfrac{9}{7}}

she already did half a hat, so we can say   \cfrac{7}{2}-\cfrac{1}{2}\implies \cfrac{7-1}{2}\implies 3

so she only needs enough fabric to make 3 more full hats, we know each one uses 9/7 ft, so

3\cdot \cfrac{9}{7}\implies \cfrac{27}{7}\implies 3\frac{6}{7}

!!!! could anyone help on these two problems? find the value of each trigonometric ratio
Setler [38]

Answers:

  • sin(C) = 24/25
  • cos(Z) = 5/13

=============================================

Explanation:

The formulas we use are

  • sin(angle) = opposite/hypotenuse
  • cos(angle) = adjacent/hypotenuse

The fraction 15/39 reduces to 5/13 after dividing both parts by the GCF 3.

If the area of a rectangle is 64cm squared, how many different perimeters are possible when the dimensions are whole numbers
FinnZ [79.3K]

Answer:

2 different perimeters, 32 cm and 40 cm

Step-by-step explanation:

Given the area of a rectangle is 64 cm squared.

We know, Area of the rectangle is = length x breath

∴  64 = 8 x 8

Hence the sides can be 8 cm by 8 cm.

So the perimeter of the rectangle is = 8 cm + 8 cm + 8 cm +8 cm

                                                            = 32 cm

Also, Area of the rectangle is = length x breath

∴  64 = 16 x 4

So the perimeter of the rectangle is = 16 cm + 4 cm + 16 cm +4 cm

                                                            = 40 cm

25,812-4.2d=31.311-5.5d
Bas_tet [7]

Let's solve your equation step-by-step.

25812−4.2d=31.311−5.5d

Step 1: Simplify both sides of the equation.

25812−4.2d=31.311−5.5d

25812+−4.2d=31.311+−5.5d

−4.2d+25812=−5.5d+31.311

Step 2: Add 5.5d to both sides.

−4.2d+25812+5.5d=−5.5d+31.311+5.5d

1.3d+25812=31.311

Step 3: Subtract 25812 from both sides.

1.3d+25812−25812=31.311−25812

1.3d=−25780.689

Step 4: Divide both sides by 1.3.

1.3d

1.3

=

−25780.689

1.3
