Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of phones produced abroad and y represent the number of phones produced locally.

The company can provide 6000 hours of labor each week and it takes 30 hours to produce the cellphone abroad and at the local factory it takes 20 hours, hence:

30x + 20y = 6000            (1)

Also, there is a total resource of $12000 each week, the cost of producing abroad is $20 and the cost of producing locally is $60. Hence:

20x + 60y = 12000           (2)

Multiply equation 1 by 3 and subtract equation 2 from the result. This gives:

70x = 6000

x = 600/7 ≈ 86

Put x = 86 in equation 1:

30(86) + 20 y = 6000

20y = 3420

y = 171

86 phones should be produced abroad and 171 phones locally

Answer:

\( \sf \: 375g \: is \: 2.5\% \: of \: 15kg\)

Step-by-step explanation:

Conversion of 15 kg into grams,

→ 1 kg = 1000 g

→ 15 kg = 15000 g

Let's find the percentage,

→ (375g ÷ 15kg) × 100

→ (375/15000) × 100

→ 0.025 × 100

→ 2.5%

Hence, the answer is 2.5%.

Answer:

\(\boxed{\underline{\tt B.\:x=-6}}\)

Step-by-step explanation:

\(\tt \cfrac{1}{25} = 5^{(x+4)}\)

(First, let's convert both sides to the same base):-

\(\tt 5^{-2}=5^{x+4}\)

(Now, cancel the base of 5 on both sides):-

\(\tt -2=x+4\)

( Subtract 4 from sides)

\(\tt x+4-4=-2-4\)

\(\tt x=-6\)

In a rectangle WXYZ, if the measure of angle 1 is 30 degrees, then the measure of angle 8 can be determined.

A rectangle is a quadrilateral with four right angles. In a rectangle, opposite angles are congruent, meaning they have the same measure. Since angle 1 is given as 30 degrees, angle 3, which is opposite to angle 1, also measures 30 degrees.

In a rectangle, opposite angles are congruent. Since angle 1 and angle 8 are opposite angles in quadrilateral WXYZ, and angle 1 measures 30 degrees, we can conclude that angle 8 also measures 30 degrees. This is because opposite angles in a rectangle are congruent.
Since angle 3 and angle 8 are adjacent angles sharing a side, their measures should add up to 180 degrees, as they form a straight line. Therefore, the measure of angle 8 is 180 degrees minus the measure of angle 3, which is 180 - 30 = 150 degrees.

So, if angle 1 in rectangle WXYZ is 30 degrees, then angle 8 measures 150 degrees.

The solution of both inequalities is (-1, 2).

Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

Answer:

x = 142°, y = 38°

Step-by-step explanation:

Since (3y+28)° and x° are vertically opposite and corresponding, this means that x = 3y + 28

We also know that the sum of angles on the same side of a transversal is always 180°. This means that:

x + y = 180

Sub in x = 3y + 28

3y + 28 + y = 180

4y + 28 = 180

4y = 152

y = 38°

Now that we know that y = 38, we can sub this back into x = 3y + 28

x = 3(38) + 28

x = 114 + 28

x = 142°

You can double check this by finding the sum of x and y, which is 142 + 38 = 180

Therefore, x = 142°, and y = 38°

The height of the fish tank should be approximately 1.981 feet which is also equivalent to 23.772 inches.

As desired capacity of the fish tank is 100 gallons, and 7.48 gallons of water are equivalent to 1 cubic foot, the desired volume of the fish tank is (100 / 7.48) cubic feet, or approximately 13.369 cubic feet.

The desired volume is stated as a number of cubic feet so the known dimensions of the fish tank must be converted from inches to feet.

length = 54 inches = 4.5 feet

width = 18 inches = 1.5 feet

The formula for the volume V of a rectangular prism with length l, width w, and height h is V = lwh. We will substitute the known dimensions into the formula and solve for h.

V = ℓwh

13.369 ≈ 4.5 × 1.5 × h

13.369 ≈ 6.75h

h ≈ 13.369 / 6.75

h ≈ 1.981

The equation 0.7(2y+13)=1.4y+9.1 will have infinite solutions , the correct option is  (A) Infinite solutions .

In the question

the given equation is

0.7(2y+13)=1.4y+9.1

From the given figure, the measure of angle OXZ is 10°.

Given that, XY and ZY are tangents to a circle with center O.

Tangent and radius of a circle meet at 90°. If we draw a radius that meets the circumference at the same point, the angle between the radius and the tangent will always be exactly 90°.

Here, angle formed at the center is

∠ZOX = 180° - ∠XYZ

∠ZOX = 180° - 20°

∠ZOX = 160°

ZO = XO = radius

Now, ΔZOX is an isosceles triangle

So, ∠ZOX +∠OXZ+∠OZX = 180°

⇒ 160° + 2∠OXZ = 180°

⇒ 2∠OXZ = 20°

⇒ ∠OXZ = 10°

Therefore, from the given figure, the measure of angle OXZ is 10°.
