What is the area, in square centimeters, of the isosceles trapezoid below?
5.9 cm
5.8 cm
14.7 cm
Answer:

Answer:

2.4 cm

Step-by-step explanation:

We know the length of segment AB and the length of segment BC. To find their midpoints, we can divide their length by 2.

Let's find the midpoint of AB.

Next let's find the midpoint of BC.

In order to find the difference between these midpoints, we can subtract the midpoint of AB by the midpoint of BC.

Therefore, the difference between the midpoints of AB and BC is 2.4 cm.

Answer:

86

Step-by-step explanation:

Since ∆JKL is an isosceles triangle, it's base angles (<L and <J) would be equal to each other.

<L is opposite to side JK, <J is opposite to side KL.

m<J is given as 47°. Therefore,

m<L = m<J = 47°

m<L = 47°

m<J + m<L + m<K = 180° (sum of triangle)

47° + 47° + m<K = 180° (substitution)

94° + m<K = 180°

m<K = 180° - 94°

m<K = 86°

Answer:

$159.75

Step-by-step explanation:

137.45/252.60 + x = 1/3

252.60 + x = 412.35

x = 412.35 - 252.60

x = 159.75

Answer:

297.2

Step-by-step explanation:

549.8 ÷ 4 = 137.45

549.8 - 252.60 = 297.2

Step-by-step explanation:

The partial sum of the geometric series is;

⇒ 125 + 25 + 5 + 1

Option A is true.

What is Geometric series?

Geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.

Given that;

The geometric series.

∑ 125 (1/5)ⁿ⁻¹ ; where, n = 1 to 4.

Now, Calculate the partial sum of the geometric series as;

The geometric series = ∑ 125 (1/5)ⁿ⁻¹

Substitute n = 1, 2, 3, 4, we get;

= 125 (1/5)¹⁻¹ + 125 (1/5)²⁻¹ + 125 (1/5)³⁻¹ + 125 (1/5)⁴⁻¹

= 125 (1/5)⁰ + 125 (1/5)¹ + 125 (1/5)² + 125 (1/5)³

= 125 + 25 + 125/25 + 125/125

= 125 + 25 + 5 + 1

Thus, The partial sum of the geometric series is;

⇒ 125 + 25 + 5 + 1

Option A is true.

Answer:

x=4, y=-2

Step-by-step explanation:

-5x+8y=-36

5x+7y=6

eqn 1+ eqn 2 gives

15y=-30

divide both sides by 15

y=-2, put in eqn 2

5x+7(-2)=6

5x=20 divide both sides by 5

x=4

-50x + 600 = 250

Answer:

Option A. x = 8

Step-by-step explanation:

Please see attached photo.

From the attached photo,

we shall determine the value of y. This can be obtained by using pythagoras theory as illustrated below:

(√80)² = 8² + y²

80 = 64 + y²

Collect like terms

80 – 64 = y²

16 = y²

Take the square root of both side

y = √16

y = 4

Finally, we shall determine the value of x. This can be obtained as follow:

From the attached photo,

x = 2y

but:

y = 4

Therefore,

x = 2y

x = 2 × 4

x = 8

Answer:

.22

regular (capuccino is incorrect)

Step-by-step explanation:

in the mocha column 25 people prefer hot and 12 people prefer cold are equal to 37 people.  25+12=37

relative frequency of preferring cold is 12.  12÷37 = .32

In the hot column 11, 25, 19, 30 people are combined for total of 85 people who prefer hot coffee.  11+25+19+30=85

relative frequency of preferring a latte is 19: 19÷85 = .22

combine regular column for 17 ÷ 28 = .61

combine mocha column for 12÷40 = .30

combine latte column for 20÷39 = .51

combine cappucino column for 27÷57 = .47

The type of coffee that has the highest percentage of people who prefer it cold is regular.  (if you combine only the cold column you will end up with cappuccino which is wrong.)

Answer:

29.4%

Step-by-step explanation:

the whole cirlce is 360 degrees which means 100%

to find the percentage of the shaded area, multiply the degrees by 100

⇒ 10.6 x 100 = 10600

then take the product and divide by 360

⇒ 1060 ÷ 360

⇒ 29.44

round to the nearet tenth of a percent

⇒ 29.4

a^2 + b^2 =c^2

Answer:

30.

Step-by-step explanation:

first term = a

3r term = ar^2

So here ar^2/ a  = r^2

r^2 = 5/180 = 1/36

r = 1/6

So missing term = 180 * 1/6 = 30.
