There is a special baking tray for skinny cakes whose length is 13 more than 2 times its width, and the area is 115 square inches. What are the dimensions of the baking tray?
Answers
Answer:
5 inches by 25 inches
Step-by-step explanation:
From the question,
Let the width of the baking tray be(w) = x inches,
Then the lenght of the baking tray(l) = (2x+13) inches
If the area of the baking tray = 115 square inches
Applying,
A = lw................. Equation 1
Therefore,
x(2x+13) = 115
2x²+13x = 115
2x²+13x-115 = 0
Using factorization method to solve the quadratic equation
2x²-10x+23x-115 = 0
(2x²-10x)+(23x-115) = 0
2x(x-5)+23(x-5) = 0
(2x+23)(x-5) = 0
Either
2x+23 = 0
x = -23/2
or
x-5 = 0
x = 5.
dimensions of the tray is
w = 5 inches
l = (2×5)+15 = 10+15 = 25 inches
Hence the dimensions of the baking tray = 5 inches by 25 inches
Which sentence explains why polygon ABCDEFGH is congruent to polygon MNOPQRST?
A.
A sequence of translations will map MNOPQRST onto ABCDEFGH.
B.
A sequence of rigid transformations will map MNOPQRST onto ABCDEFGH.
C.
A sequence of rotations will map MNOPQRST onto ABCDEFGH.
D.
A sequence of reflections will map MNOPQRST onto ABCDEFGH.
Answers
Answer:
correct option if Option D
Answer:
The answer is B.
Step-by-step explanation:
It can't be A, C, or, D because if the polygons were in a certain position, those transformations wouldn't work.
The definition of a rigid transformation is either a translation, rotation, or reflection. Therefore it must be B.

Step-by-step explanation:
use trig functions
2 sides and 1 angle given
Sides given
hypotenuse -> xopposite side to 30˚ -> 4Angle
30˚trig function associated with hyp and opp is sin
sin(x) = opp/hyp
substitute
sin 30˚ = 4/x
solve for x
0.5 = 4/x
0.5x = 4
x = 8
Answer:
Step-by-step explanation:
sin 30° = [tex]\frac{4}{x}[/tex]
x = [tex]\frac{4}{sin 30}[/tex]
x = [tex]\frac{4}{0.5}[/tex]
x = 8

Answer:
P = 11 4/5
Step-by-step explanation:
Let L = 2 1/2 and w = 3 2/5
[tex]P=2(2\frac{1}{2})+2(3\frac{2}{5})\\\\P=5+6\frac{4}{5}\\\\P=11\frac{4}{5}[/tex]
The perimeter as a mixed number is P = 11 & 4/5, but it seems like your teacher only wants the whole part of the answer. So you'll just type 11.
============================================================
Work Shown:
1/2 = 0.5
2 & 1/2 = 2 + 1/2 = 2 + 0.5 = 2.5
This shows that L = 2.5 ft
Similarly, W = 3.4 ft because 3+2/5 = 3+0.4 = 3.4
-----------------
Plug those L and W values into the perimeter formula
P = 2L + 2W
P = 2*2.5 + 2*3.4
P = 5 + 6.8
P = 11.8
now convert back to a mixed number
11.8 = 11 + 0.8
11.8 = 11 + 8/10
11.8 = 11 + 4/5
11.8 = 11 & 4/5
The perimeter is 11 & 4/5 ft. In other words, the perimeter is 11 whole feet plus an additional 4/5 of a foot.
Your teacher seems to only want the whole part of the answer, assuming they only want the stuff in the box indicated with a question mark. If that's the case, then you'll type 11 into the box to write the final answer.

A full waterbed mattress is 6 ft by 2 ft by 1 ft. The mattress is to be filled with water that weighs 62.4 lb /ft3. Find the weight of the water in the mattress to the nearest pound.
Answers
Answer:
749 lbs
Step-by-step explanation:
weight of the water in the mattress = volume of the mattress x weight of water
volume of the mattress = volume of a cuboid = length x width x height
6 x 2 x 1 = 12 ft³
weight of the water in the mattress = 12 x 62.4 = 748.8 lbs

Answers
The distance travelled by the Lucas will be equal to 105 miles.
What is an average speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.
The average speed is defined as the total distance travelled by train in total time.
Given that Lucas took an express train into the city last weekend without any stops. He boarded the train at 9:30 am and arrived in the city at 11:15 a.m. The train's average speed was 60 miles per hour.
Time = 105 minutes = 105 / 60 = 1.75 hours
The distance travelled by train will be calculated as,
Distance = Speed x Time
Distance = 60 x 1.75
Therefore, the distance travelled by Lucas will be equal to 105 miles.

$5 out of every $100 a worker earns goes for clothes. On $4,000 a year wages, how much does he spend on clothes?
Answers
(If he uses the 200 on clothes he basically only earns $3,800 yearly)
If $5 out of every $100 a worker earns goes for clothes, the worker spends $200 on clothes from a $4,000 annual wage.
To determine how much a worker spends on clothes from a $4,000 annual wage, we need to calculate 5% of that amount.
The worker spends $5 out of every $100 earned on clothes. This means the worker spends 5% of their earnings on clothes.
To find 5% of $4,000, we can multiply $4,000 by 0.05:
$4,000 * 0.05 = $200
This calculation is based on the assumption that the worker consistently spends 5% of their income on clothes throughout the year.

Step-by-step explanation:
The triangles are similar because they have the same angles.
Make a proportion to solve for AC which we will substitute with variable x.
AM = MB = 4
AB = AM + MB = 8
BN = NC = 3
BC = BN + NC = 6
big triangle sides: 8, 6, x
small triangle sides: 4, 3, 6
