Answer:

The total fraction shaded is 1/2

Step-by-step explanation:

Here, we want to know the fraction shaded

As we can see, the box is originally divided into 4

So each of the 4 parts are 1/4

for the first part, we have 4 divisions;

This means each of the divisions with respect to the whole fraction will be 1/4/4 = 1/16

Now, two of these are shaded, making 1/16 and 1/16

Secondly, we have half of the 1/4 : So with respect to the whole, we have 1/4/2 = 1/8

for the third part, the whole 1/4 is shaded

and lastly, we have an unshaded 1/4

so, the total fraction shaded will be ;

1/16 + 1/16 + 1/4 + 1/8

= (1 + 1 + 4 + 2)/16 = 8/16 = 1/2

On one side of the balance scale, Henry placed a 6-gram weight. On the other side of the scale, he placed a ballet slipper.
olchik [2.2K]

Answer:

  • <u><em>A. 6,000 miligrams</em></u>

Explanation:

A <em>balance scale</em> is balanced when the weights on both sides are equal. Then, since the image shows that both sides are equal, the weight of the <em>6-gram weight</em>, placed by Henry on one side of the balance scale is equal to the weight of the <em>ballet slipper </em>placed on the other side.

  • Weight of the balance slipper = weight of the 6-gram weight
  • Weight of the balance slipper = 6 grams

<u>Conversion of units: </u>

  • 6 grams × 1,000miligrams/1gram = 6,000 miligrams

  • Weight of the balance slipper = 6,000 miligrams

That is the option A.

X, Y and Z form the vertices of a triangle. XY = 12.4m, XZ = 10.4m and YZ = 8.7m. Find the angle ∠ YXZ rounded to 1 DP.
sweet-ann [11.9K]

Answer:

43.8°

Step-by-step explanation:

Applying,

Cosine rule,

From the diagram attached,

x² = y²+z²-2yxcos∅.................... Equation 1

where ∅ = ∠YXZ

Given: x = 8.7 m, y = 10.4 m, z = 12.4 m

Substitute these values  into equation 1

8.7² = 10.4²+12.4²-[2×10.4×12.4cos∅]

75.69 = (108.16+153.76)-(257.92cos∅)

75.69 = 261.92-257.92cos∅

collect like terms

257.92cos∅ = 261.92-75.69

257.92cos∅ = 186.23

Divide both sides by the coefficient of cos∅

cos∅ = 186.23/257.92

cos∅ = 0.722

Find the cos⁻¹ of both side.

∅ = cos⁻¹(0.7220)

∅ = 43.78°

∅ = 43.8°
