Answer:
[tex]147.6\:\mathrm[/tex]
Step-by-step explanation:
The perimeter of a polygon is simply sum of the lengths of all sides of the polygon.
Therefore, we can find this polygon's perimeter by adding up the length of each of its sides:
[tex]9.8+9.8+11.7+9.8+21.5+21+11.7+9.8+31.3+11.2=\boxed{147.6\:\mathrm{m}}[/tex]
Since there is a lot to keep track of, I'd recommend picking any side and moving clockwise/counter-clockwise until you get all sides.
What is the equation of the line?
Answer:
y = -7
Step-by-step explanation:
This is a horizontal line
The y value does not change
It is of the form y=
y = -7
Answer:
y = -7
Step-by-step explanation:
A horizontal line has an equation of the form
y = k
where k is the y-coordinate of every point on the line.
We see that every point on this line has y-coordinate -7, so the equation is
y = -7
Mrs. Lia has 11 pounds of modeling clay. She divides the clay into 1 2 - pound blocks. If Mrs. Lia sets aside 7 of the blocks and gives the rest to the students in her art class, how many 1 2 - pound blocks of clay does Mrs. Lia give to her class?
Answer:
Assuming she is dividing into 1/2 lb blocks.
15 of the 1/2 lb are given to the class.
Step-by-step explanation:
She can make 22 of the 1/2 lb blocks out of 11 lbs. If she sets aside 7, then 22-7=15. She has 15 of the 1/2lb blocks left to give to the class.

Answer:
9,375 J
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Mass (m) = 30 kg
Moving speed or Velocity (v) = 25 m/s
So, we can calculate kinetic energy by using following formula,
Kinetic energy = (1/2)m[tex]v^{2}[/tex]
By putting the value in the formula, we get
Kinetic energy = (1/2) 30 × [tex]25^{2}[/tex]
= 15 × 625
= 9,375 J
Can someone please help me out
Answer:
x = 8, A = 182 units²
Step-by-step explanation:
The perimeter P of a rectangle is calculated as
P = 2l + 2b ( l is the length and b the breadth )
Given P = 66, then
2(7) + 2(3x + 2) = 66 ← distribute and simplify left side
14 + 6x + 4 = 66
6x + 18 = 66 ( subtract 18 from both sides )
6x = 48 ( divide both sides by 6 )
x = 8
Then
3x + 2 = 3(8) + 2 = 24 + 2 = 26, so
A = 7 × 26 = 182 units²

Given:
The figure of a circle.
Measure of arc = 176°
Measure of angle = (27x+7)°
To find:
The value of x.
Solution:
We know that the measure of central angle is equal to measure corresponding intercepted arc and the measure of central angle is twice of the measure of subtended angle on that arc.
So, the measure of arc is twice of measure of subtended angle on that arc.
[tex]m(arc FH)=2\times m\angle FGH[/tex]
[tex]176^\circ=2\times (27x+7)^\circ[/tex]
[tex]\dfrac{176^\circ}{2}=(27x+7)^\circ[/tex]
[tex]88^\circ=(27x+7)^\circ[/tex]
Now,
[tex]88=27x+7[/tex]
[tex]88-7=27x[/tex]
[tex]\dfrac{81}{27}=x[/tex]
[tex]3=x[/tex]
Therefore, the value of x is 3.
The level of the tide in a harbor changes from 813 8 1 3 feet to 256 2 5 6 feet above sea level over a period of 212 2 1 2 hours. What is the change in tide level per hour over this period of time? Feet per hour
Answer:
-2.63 ft./hour
Step-by-step explanation:
The level of the tide in a harbor changes from 813 feet to 256 feet above sea level over a period of 212 hours. What is the change in tide level per hour over this period of time?
Solution:
The initial tide level was 813 feet while the final tide level was 256 feet above sea level within a period of 212 hours.
The change in tide level per hour is the ratio of the change in tide level to the period taken. Hence:
Change in tide level per hour = (Final tide level - initial tide level) / time taken
Change in tide level per hour = (256 ft. - 813 ft.) / 212 hours
Change in tide level per hour = -2.63 ft./hour
A paint shop mixes colours to the customers taste. To make 1 litter of base white, 2 milliliters of B and 0,25 milliliter of C. how much of each component will he use for mixture containing 750 litres of base white? write each answer in litres.
Answer:
Mixing quantity of B = 1.5 liter
Mixing quantity of C = 0.1875 liter
Step-by-step explanation:
Given:
Mixing ratio;
1 liter white base , 2 milliliter of B , 0.25 milliliter of C
Find:
Mixing quantity in 750 liters
Computation:
2 milliliter of B = 0.002 L
0.25 milliliter of C = 0.00025 L
Mixing quantity of B = 750 x 0.002
Mixing quantity of B = 1.5 liter
Mixing quantity of C = 750 x 0.00025
Mixing quantity of C = 0.1875 liter

Two positive integers are 3 units apart on a number line. Their product is 108.
Which equation can be used to solve for m, the greater integer?
a). m(m – 3) = 108
b.) m(m + 3) = 108
c.) (m + 3)(m – 3) = 108
d.) (m – 12)(m – 9) = 108
Answer:
d) the numbers are 9 and 12
Step-by-step explanation:
set each factor equal to 108:
m-12=108
m = 120
*************
m-9=108
m=117
*************
120 and 117 are 3 units apart

The figure shows Triangle ABC and some of its transformed images on a coordinate grid:
A coordinate plane is shown. Triangle ABC Is formed by the points 2 commas 5, 2 comma 3, and 4 commas 3. Triangle 2 is formed by the points negative 3 commas 5, negative 3 commas 3, and negative1 comma 3. Triangle 1 is formed by the points negative 4 commas 5, negative 4 commas 3, and negative 6 commas 3. Triangle 3 is formed by the points negative 6 commas 2, negative 4 commas 2, and negative 4 commas 0. Triangle 4 is formed by the points 2 commas negative 1, 4 commas negative 1, and 4 commas negative 3.
Which of the four triangles was formed by a translation of Triangle ABC?
1
2
3
4
Answer:
Triangle 2
Step-by-step explanation:
The translation is a type of transformation, where the figure is just translated or simply moved from its original place.
The figure is not rotated or dilated but simply moved.
Here, we can see that only figure or triangle 2 is like the triangle ABC. Other triangles have undergone other transformations.
So, the correct answer is triangle 2.

For the following geometric sequence find the explicit formula.
{12, -6, 3, ...}
Answer:
Tn = 12(-1/2)^n
Step-by-step explanation:
We have the nth term of a geometric sequence as
Tn = ar^n-1
a is the first term
r is the common ratio
n is term number
by dividing the second term by the first, we can have the common ratio
We have this as -6/12 or 3/-6 = -1/2
a the first term is 12
So we have the explicit formula as;
Tn = 12(-1/2)^n
Which is equivalent to a+(-a)
Answer:
Step-by-step explanation:
a+(-a)
=a-a

how many questions out of 42 do I need to get right to score 75?
Answer:
31 questions, but it's impossible to score 75%.
Step-by-step explanation:
It's impossible to get exactly a score of 75% out of 42 questions. However, you can get the next closest percentage, which is rounded up to 74% with 31 questions right out of 75.
This is because 31 / 42 = 0.738... You can round 0.738 to 0.74. Then multiply 0.74 by 100, which gives you 74. This means the closest score you can get to 75 is 74% with 31 questions.
You can also score 76% with 32 questions right out of 42 questions. This is because 32 / 42 = 0.761... You can round 0.761 to 0.76. Then multiply 0.76 by 100, which gives you 76.

Today, everything at a store is on sale. The store offers a 18% discount.
a. The regular price of a T-shirt is $20. What is the discount price?
Answer:
Discount : 3.60$
Discounted shirt price: 16.40$
Step-by-step explanation:
If there is a 18% then we can get the discounted price you get by multiplying 20$ by 18%
So we can change 18% to decimal if we need to by just moving a decimal point 2 decimal points to the left. so .18.
Now 20*.18 = 3.60$ | That is the discount you get on sale. To get the actual discount price you just need to subtract 20-3.6= 16.40$
Answer:
Step-by-step explanation:
To calculate the 18% discount, convert 18% into the equivalent decimal fraction 0.18 and then multiply the regular price ($20) by 0.18; the discount is thus $3.60.
Subtract the discount, $3.60, from the regular price ($20) to obtain the discount price: $16.40.
********************************
Alternatively, take the shortcut of multiplying $20 by (1.00 - 0.18), or
$20 by 0.82. The result (i. e., the discount price) is the same: $16.40
