math in order to have an overall average equivalent to the first quarter? Write your answer
in the box.

Answer:

angle FDA = 75 degrees

angle JAI = 75 degrees

Step-by-step explanation:

In ΔDCE,

angle D + angle C + angle E = 180......(sum of the interior angles of a triangle is always 180 degrees)

angle D + 80 + 25 = 180

angle D + 105 = 180

angle D = 180 - 105

angle D (I. e angle CDE ) = 75 degrees

Now, angle CDE and angle FDA are vertically opposite angles, so,

angle CDE = angle FDA..... (vertically opposite angles are congruent to each other)

therefore, angle FDA = 75 degrees

Now, angle CDE and angle BAD are corresponding angles, so,

angle CDE = angle BAD...... ( corresponding angles are congruent to each other)

angle BAD = 75 degrees

Now, angle BAD and angle JAI are vertically opposite angles, so,

angle BAD = angle JAI..... (vertically opposite angles are congruent to each other)

therefore, angle JAI = 75 degrees

Hello! answer: 45

Step-by-step explanation:

90 + 45 + 45 = 180 therefore z = 45 hope that helps!

Hi there!

Answer:

2.     4x + 5y = 20

Step-by-step explanation:

Determine the slope of each of the equations;

y = mx + c

where;

m is the slope

In each of the given equations, make y the subject of the formula

1. 5x + 4y = 20

       4y = 20 - 5x

         y = (20/4)  -  (5x/4)

         y = 5 - 5x/4

m = -5/4

2. 4x + 5y = 20

      5y = 20 - 4x

        y = 4 - 4x/5

m = -4/5 = -0.8

3. 5x - 4y = 20

        4y = 5x - 20

          y = 5x/4  - 5

m = 5/4

4. 4x - 5y = 20

          5y = 4x  -  20

            y = 4x/5  - 4

m = 4/5

The question says, which of the slope is greater than - 1 but less than 0

- 1 < m  < 0

The only equation with slope greater than -1 but less than 0 is 4x + 5y = 20, with slope -4/5 = -0.8

Answer:

I think answer is

5.X+11

Answer:

B. 63

Step-by-step explanation:

There are two similar triangles given in the diagram above. Since they area similar, they also have corresponding side lengths that are proportional.

Therefore:

(6 + 3)/3 = x/21

9/3 = x/21

3 = x/21

Cross multiply

21*3 = x

63 = x

x = 63

Answer:

1792

Step-by-step explanation:

The sides of the rectangle is 7 and 4

7x, 4x

2(7x+4x) = 176

14x + 8x= 176

22x= 176

Divide both sides by the coefficient if x which is 22

x= 176/22

x= 8

7x

= 7(8)

= 56

4x

= 4(8)

= 32

Area of the rectangle

= 56×32

= 1792

Answer:

False

Step-by-step explanation:

A regular polygon may be defined as the polygon that have sides of equal length known as equilateral and angles made up of equal angles, known as equiangular.

The [tex]$\text{number of lines}$[/tex] of symmetry in a regular polygon is always equal to the number of sides of the polygon. For example, a regular pentagon have 5 sides, so the lines of symmetry of the regular pentagon is also 5, a square having 4 sides also has 4 lines of symmetry.

Answer:

  outcomes (top to bottom): SS, SG, GS, GG

  all probabilities are 0.25

Step-by-step explanation:

Each outcome is identified by the labels on the ends of the corresponding tree branch, in order left-to-right. The top one is SS, for example, and the next one down is SG. Continuing down the tree, the outcomes are GS and GG.

Each letter has a probability of 1/2, so any pair of letters will have a probability of (1/2)(1/2) = 1/4 = 0.25.

__

This method of identifying outcomes and their probabilities can ensure that you find all outcomes. The sum of probabilities should be 1.00 if the tree is properly constructed.

Answer:

x = 38°

Step-by-step explanation:

Complementary angles = 90°

90° = x + x+14

90° = 2x + 14

104 = 2x

x = 52°

the next angle should be 52 - 14 = 38°

So x = 38°

Answer: B

Step-by-step explanation:

If you change them all to decimals.

4.8% = .048

1/20 = .05

4.1 x [tex]10^{-1}[/tex] = .41

[tex]\sqrt{4}[/tex] = 2

So, that would be least to greatest.

Answer:

135 degrees

Step-by-step explanation:

It is as isosceles trapezoid, so the the base angles are congruent. The sum of the inner angles is 360 degrees

2(4x-7) + 2(11x -8) = 360

8x - 14 + 22x -16 = 360

30x = 390

x = 13

angle F = angle G

angle G = 11 * 13 - 8 = 135 degrees

Answer:

circumference is given by πd, where d is the diameter of the circle.

This implies, the circumference= 22/7*150m

=3300/7=471.429m

Answer:

Step-by-step explanation:

113+90+90+12x+7=360(sum of four angles is always 360 degree)

300+12x=360

12x=360-300

x=60/12

x=5

Answer:

X = 5

Step-by-step explanation:

Shapes with 4 sides have angles that add to 360 degrees

So you have two right angles and 113 degrees.

This is

90+90+113=293

360-293=67

12x5=60

60+7=67

This means that x=5

Answer:

55 inches = 4 feet 7 inches

Step-by-step explanation:

Because Michael is 5 inches taller so 50+5=55, then divided by 12 = 4 remainder 7. So that means Michael is 55 inches tall, or 4 feet and 7 inches

Answer:

Option (6)

Step-by-step explanation:

By applying sine rule the given triangle XYZ,

sin(X) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

Measure of opposite side (XY) = 12

Measure of Hypotenuse (XZ) = 37

By substituting these values in the given expression,

sin(X) = [tex]\frac{12}{37}[/tex]

Therefore, Option (6) will be the correct option
