CAN SOMEONE PLEASE HELP?!
Answer:
70in.
Step-by-step explanation:
Since the given formula for perimeter is [tex]2l + 2w[/tex], all that's needed is to fill in the blanks with the numbers they give us.
[tex]2l + 2w[/tex] (Fill in for given length and width)
[tex]2(20)+2(15)[/tex] (Multiply)
[tex]40 + 30[/tex] (Add)
[tex]70[/tex]
It tells us that length ([tex]l[/tex]) is 20 and that width ([tex]w[/tex]) is 15. So all that we have to do is use the equation it gave us to solve the equation.
I hope this helped :)
Step-by-step explanation:
Hey there!
Here;
Length (l) = 20 in
Width (w) = 15 in
Perimeter(p) = ?
We have;
Perimeter of rectangle (p) = 2l + 2w
= 2(l+w)
= 2(20+15)
= 2*35
= 70 inches
Therefore, perimeter of rectangular picture is 70 inches.
Hope it helps!

Part B
What is the measurement of angle G? Part C
Let the variable c represent the measurement of angle C. Use the measurement of angle G to write an equation that you can use to solve for c. Part D
What is the measurement of angle C?
Finishing the angles of the smaller triangle if E is 90 and F is 30 then G needs to be 180-90-30 = 60 degrees.
Angles G and C are supplementary angles which need to equal 180 degrees
Angle c = 180-g = 180-60 = 120
Angle c = 120 degrees.
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then Δ EGF
∠ G = 180° - (90 + 30)° = 180° - 120° = 60°
------------------------------------------------------------
c and g are adjacent angles and sum to 180° , then
c + g = 180° , that is
c + 60° = 180° ( subtract 60° from both sides )
c = 120
That is ∠ C = 120°

what two numbers add up to 55 and multiply to -375
Answer:
-6.13406 and 61.13406
Step-by-step explanation:
x + y = 55
x × y = -375
y = 55 - x
x × (55 - x) = -375
55x -x² = -375
x² - 55x - 375 = 0
solution of a quadratic equation :
x = (-b ± sqrt(b² - 4ac))/(2a)
a=1
b=-55
c=-375
x = (55 ± sqrt(55² + 4×375))/2 = (55 ± sqrt(4525))/2 =
= (55 ± sqrt(25 × 181))/2 = (5×11 ± 5×sqrt(181))/2 =
= 5/2 × (11 ± sqrt(181)) =
= 61.13406... or -6.13406...
y = 55 - 5/2×(11 ± sqrt(181)) = 55/2 ± 5/2×sqrt(181) =
= -6.13406... or 61.13406...
find the value of x. round to the nearest tenth.
Answer:
x = 26.4
Step-by-step explanation:
Hi there!
What we need to know:
Basic trigonomic ratios (θ is the reference angle):
Sine θ = opposite / hypotenuseCosine θ = adjacent / hypotenuseTangent θ = opposite / adjacentGiven the diagram, we can see that the reference angle is x. We are also given the hypotenuse (9) and the opposite side length (4). With the opposite and the hypotenuse, we know that we need to use the sine ratio:
sin(x) = 4/9
To solve for an angle given the side lengths, we use the inverse functions:
x = sin^-1 (4/9)
x = 26.4

At Factory Y, a worker's wages for a 40-hour week is $200. She is paid 10% of her regular weekly wages for every hour that she works overtime. At the end of a certain week she received $380. Calculate the number of hours of overtime that she worked.
Answer:
She worked 18 hours of overtime.
Step-by-step explanation:
If she works 40 hours per week and gets $200, subtract $380 - $200 = $180.
If you multiply $180 by 0.1 (which is 10% converted to a decimal), you get 18 which is your final answer.
The original price of a computer was reduced by 225 dollars. The new discounter price is 1274 dollars.
Answer:
1499
Step-by-step explanation:
Given that :
New discounted price = 1274
Let original price = p
Reduction in original price = 225
Original price is the sum of the reduction and the new discounted price
The Original price = Reduction in original price + new discounted price
P = 225 + 1274
P = 1499

POSSIBLE POLYGONS Determine if it is possible for a regular polygon to have an interior angle with the given angle measure. Explain your reasoning a. 165 b. 171 c. 75 d. 40
Answer:
yes for all 4.
Step-by-step explanation:
I am not sure I see the whole information.
but if the question truly is simply, whether a polygon can have an internal angle of 165 or 171 or 75 or 40 degrees, then the answer is a resounding yes to all 4.
the simplest polygon is a triangle.
the sum of all angles in a triangle is always 180 degrees.
so, any angle smaller than 180 degrees is a possible internal angle in a triangle (and therefore in polygons in general), because the difference to 180 can then be split into 2 angles (e.g. half/half).
so, if one angle is 165 degrees, then the other two angles have to have 15 degrees together (e.g. 10 and 5, or 7 and 8, or 2 and 13, or ...). they will be narrow angles, but they are still angles.
similar for 171 degrees. now the other two angles have to have only 9 degrees together. like 5 and 4.
for 75 degrees the other two angles must have 180-75 = 105 degrees together. like 20 and 85.
for 40 degrees the other two angles must have 180-40 = 140 degrees together. like 90 and 50.

The discount on a toy is 40% the toy robot is on sale for $54 find the original price
Answer:
The original price is $90.
Step-by-step explanation:
100% - 40% = 60%
[tex]\frac{54}{y} :\frac{60}{100}[/tex]
y × 60 = 54 × 100
60y = 5400
60y ÷ 60 = 5400 ÷ 60
y = 90
Answer:
90
Step-by-step explanation:
If the discount is 40%, we are still paying 100-40% or 60 %
original price * 60% = sale price
original price * .6 = 54
Divide each side by .6
original price = 54/.6
original price =90

The Marked price of a jacket at a dealer's shop is 2400. The dealer allows a discount of 15% to the retailer. As the company's policies the marked price of the retailer should be the same as the dealer's marked price. What SP should the retailer fix for the jacket? What would its final price be if 10% VAT is imposed? What would be the actual gain of retailer?
Ans
2280,2502,240
Answer:
2400
2640
360
Step-by-step explanation:
I am not sure the description is totally clear.
my assumptions are (based on my interpretations of the text) :
the retailer buys from the dealer with 15% discount.
but the retailer has to sell the jacket for the same price as the dealer.
so, both mark the sale price as 2400.
if the customer buys from the retailer, the retailer makes 15% profit (the discount he got from the dealer).
15% = 2400 × 15/100 = 24 × 15 = 360
the retailer makes this profit no matter what other fees or taxes are added.
if the customer buys from the dealer, the dealer makes these 15% and some more (we don't know how much) profit.
now, the final price is to include also 10% VAT
100% = 2400
1% = 2400 / 100 = 24
10% = 24 × 10 = 240
so,
final price = SP + VAT = 2400 + 240 = 2640
work out the sizeof angle X
Answer:
x = 13°
Step-by-step explanation:
Since the lines are parallel , then
the lower left vertex of the triangle = 85° ( alternate angles )
the lower right vertex of the triangle = 180° - 98° = 82° ( adjacent angles )
Then
x = 180° - (82 + 85)° = 180° - 167° = 13° ( angle sum of triangle )
The sum of three consecutive even numbers is 24 , find the numbers.
Answer:
three consecutive even integers whose sum is 24 are 6, 8 and 10.
Divide the total by amount of numbers. This will be the middle value:
24/3 = 8
The numbers are consecutive even numbers so use the even number below and above 8, which are 6 and 10.
6 + 8 + 10 = 24
The 3 consecutive even numbers are 6, 8 and 10

Toula has just baked a cake in the shape of a rectangle. She
wants to divide the cake into two right-angled triangles by
cutting along a diagonal of the cake. Toula is then going to place
a cake ribbon around the outside of each of the two triangular
pieces of cake. If the length of the cake is 32 cm and its width is
24 cm, how much cake ribbon will she need to buy, giving your
answer to an appropriate accuracy.
Answer:
192 cm
Step-by-step explanation:
length of the ribbon needed = perimeter of right angled triangle x 2
to determine perimeter, the value of the hypotenuse needs to be known
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
32² + 24²
= 1024 + 576
= 1600
square root = 40
length of rope = 2 x (40 + 32 + 24) = 192
