Mathematics
1 answer:
miss Akunina [59]3 years ago
8 0

Answer:

m∡A = 50°

Step-by-step explanation:

since they are complementary they must equal 90°

4x+6 + 4x-4 = 90

8x + 2 = 90

8x = 88

x = 11

∡A = 4(11)+6 = 44+6 = 50

A farmer owns chickens and sheep. One day, he observed that when his animals were all together, there were at least 30 legs but
motikmotik

Answer:

c+s < 12, 2c+4s >= 30.

Step-by-step explanation:

Known: at least 30 legs, less than 12 heads.

Each animal has one head, so if there are less than 12 heads, then c + s < 12.

Sheep have four legs and chickens have two legs, so if there are at least 30 legs, then # of chicken legs + # of sheep legs >= 30, ----> c(2) + s(4) >= 30, ----> 2c + 4s >= 30.

The graph attached models the problem is you set the x axis as "c" (# of chickens) and y axis as "s" (# of sheep).

Graph. <br> f(x)=|2x+4|+1<br> use the ray tool to graph the absolute value function
MA_775_DIABLO [31]

Answer:

We are given the function, f(x) = |2x+4| + 1.

Now, as we can see that this function is obtained after applying following transformation to the function g(x) = |x|.

1. Dilation i.e. shrinking the graph horizontally by 2 units

2. Translation i.e. shifting the figure in 4 units to the left and 1 unit up.

Hence, after plotting the function f(x) = |2x+4| + 1, we get the following graph.

At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of silk and cotton fabrics for a dress.
rewona [7]

Answer:

Answer:

Silk = x = 1.5 yards

Cotton = y = 2.75 yards

Step-by-step explanation:

x + y = 4.25

16.90x + 4y = 36.35

1. The solution to the equation represent number of yards of silk and number of yards of cotton bought.

2.

x + y = 4.25 (1)

16.90x + 4y = 36.35 (2)

Multiply (1) by 4

4x + 4y = 17 (3)

16.90x + 4y = 36.35 (2)

Subtract (3) from (2)

16.90x - 4x = 36.35 - 17

12.90x = 19.35

Divide both sides by 12.90

x = 19.35 / 12.90

= 1.5

x = 1.5 yards

Substitute x = 1.5 yards into (1)

x + y = 4.25

1.5 + y = 4.25

y = 4.25 - 1.5

= 2.75

y = 2.75 yards

Silk = x = 1.5 yards

Cotton = y = 2.75 yards

An equilateral triangle with side lengths of 8.7 centimeters is shown. An apothem has a length of a and the radius has a length
shutvik [7]

Options A,B and D. The correction about the area of the triangle are

  • The apothem can be found using the Pythagorean theorem.
  • The apothem can be found using the tangent ratio.
  • The length of the apothem is approximately 2.5 cm.

<h3>How to solve for the length of the Apothem using the Pythagoras theorem</h3>

Firstly this is an equilateral triangle

3 of the sides have the length of 8.7cm

b = half of 8.7

= 4.35cm

To get A we have

a² + b² = c²

a² + 4.35² = 5²

When we solve this out we would have

a² = 25 - 18.9225

a ≈ 2.5 cm.

Hence we have proved that the first option is correct.

<u>For B,</u>

In an equilateral triangles, each of the angles = 60 degrees

60/2 = 30 is the angle that is made from the base

<h3>using tangent ratios </h3>

a / 4.35 = tan 30

then a = 4.35 tan 30

This would also give us an approximate of 2.5

For D

The calculations we have done based on the statements in A and B shows that D is correct as 2.5.
