Answer:

y=60°

x=12°

Step-by-step explanation:

because the propertiy of parallelogram is the opposite side have equal measurement.

that is why y=60°

x+3=15 the paralla side are equal

x=15°-3°

x=12°

proof》》》》x+3=

12°+3°=15°

15°=15°

 P= 19.42mm

  A= 18.32mm²

Answer:

Half of 6 is 3(new radius)

2 x 3.14 x 3 = 18.84, 18.84 divided by 2 = 9.42

2 + 2 + 2 = 6

6 - 2 = 4

Add lengths:

9.42 + 6 + 4 = 19.42 mm is your perimeter

2 x 2 = 4

3^3 = 9

9 x 3.14 = 28.26, 28.26 divided by 2 (semi circle) = 14.13

Add areas:

4 + 14.13 = 18.13 mm2 is your area

Answer:

[tex]0.625kg[/tex]

Step-by-step explanation:

we are given half-life of PO-210 and the initial mass

we want to figure out the remaining mass after 420 days

in order to solve so we can consider the half-life formula given by

[tex] \displaystyle f(t) = a {0.5}^{t/T} [/tex]

where:

since it halves every 140 days our T is 140 and t is 420. as the initial mass of the sample is 5 our a is 5

thus substitute:

[tex]\displaystyle f(420)=5\cdot{0.5}^{420/140}[/tex]

reduce fraction:

[tex]\displaystyle f(420)=5\cdot{0.5}^{3}[/tex]

By using calculator we acquire:

[tex]\displaystyle f(420)=0.625[/tex]

hence, the remaining sample after 420 days is 0.625 kg

Answer:

Step-by-step explanation:

This is just simple addition so there really isn't anything to talk about.

Just note that -5 1/2+6 3/4=1 1/4.

Then, we do 1 1/4+(-4 1/4)

This is just -3.

Answer: A: 30

Step-by-step explanation: 2 hours in minutes is 120 minutes.

(60 minutes is in an hour so multiply 60 * times 2=120)

120 divided by 4 is 30. You're splitting 120 minutes into 4 pieces.

30 is the answer. Happy Women's Month! #BeBrainly

Answer:

Actual distance between the two cities given on the map = 78.0 miles

Step-by-step explanation:

Scale used for the actual distance between two cities on a map is,

5 in. = 15 mi.

[tex]\frac{5}{15}[/tex] in. = [tex]\frac{15}{15}[/tex] mi.

1 mi. = [tex]\frac{1}{3}[/tex] in.

1 inch = 3 miles

Therefore, 26 inches on the map = 26 × 3

                                                        = 78 miles

Therefore, actual distance between the two cities given on the map = 78.0 miles

Answer:

We reject H0 and conclude that local average time on the internet is

different from the national average

Step-by-step explanation:

H0 : μ = 6

H0 : μ ≠ 6

Test statistic :

(xbar - μ) ÷ (s/√(n))

(6.5 - 6) / (2 / √64)

0.5 / (2/8)

0.5 / 0.25

Test statistic = 0.5 / 0.25

Test statistic = 2

We obtain the Pvalue :

Using the Pvalue from test statistic (Z) score calculator :

Pvalue = 0.0455

α = 0.05

Since Pvalue < α ; We reject H0 and conclude that local average time on the internet is

different from the national average

Answer:

<1 = 112degrees

<2 = 33degrees

Step-by-step explanation:

From the figure, the sum of interior angles of the larger triangle is equal to the exterior, hence;

<1 + 15 = 127

<1 = 127 - 15

<1 = 112degrees

For the smaller triangle;

<1 = <2 + 79

112 = <2 + 79

<2 = 112-79

<2 = 33

Hence the measure of <2 is 33degrees

Answer:

$567 after tax

Step-by-step explanation:

first, let's multiply 525 by 0.08 because he paid 8% (0.08) of 525 in tax.

525(0.08)= 42

now, let's add them together, because the question asks for the total cost.

525+42=567

$567 after tax

Answer:

x = 90°

3x = 270°

Step-by-step explanation:

Split the shape in half through the plane of 3x and x.

We can find the angle of x/2 is 45°.

Since x/2 = 45°, then we can fid that x=90°.

To find 3x, we simply multiply 90° 3 times.

So 3x = 270°.

Answer:(2) (3) (4)

Step-by-step explanation:

Answer:

1. 2

2. 5.2

3. (c * 2) - 3= a

4. ($85 + $35 * h)

Step-by-step explanation:

1. |4−2| (simplified)

= |2|

=2

2. 2a^2 = 5.2

(22)(1.3)

=(4)(1.3)

=5.2

(2.6 - (2*1.3))=

5.2 - (2.6 - 2.6) = 5.2

3. (c * 2) - 3= a

4. ($85 + $35 * h)

Answer:

x=7

Step-by-step explanation:

since its a square, all sides are the same so 5x-11 = 6x-18 and then solve it :)

Answer:

(3,2)

Step-by-step explanation:

3x-2y=5

x+2y=7     Add them up

4x=12     Solve for x

x=3

3+2y=7   Plug it back into either one of the parent functions and solve for y

2y=4

y=2

(3,2) That's the point where the two lines intersect each other.

Answer:

a = 0, b = 7

a = 1, b = 6

a = 2, b = 5

a = 3, b = 4

a = 4, b = 3

a = 5, b = 2

a = 6, b = 1

a = 7, b = 0

Step-by-step explanation:

the sum of a and b must equal 7 because 4 x 7 = 28
