find two numbers whose ratios is 3 to 5 and whose sum is 88
Answer:
33 and 55
Step-by-step explanation:
[tex]\frac{x}{y}: \frac{3}{5}[/tex]
x + y = 88
3 + 5 = 8
[tex]y(\frac{x}{y}): y(\frac{3}{5})[/tex]
[tex]x= \frac{3}{5}y[/tex]
[tex]y+\frac{3}{5}y=88[/tex]
[tex]\frac{8y}{5}=88[/tex]
[tex]5(\frac{8y}{5})=5(88)[/tex]
8y = 440
8y ÷ 8 = 440 ÷ 8
y = 55
x + y = 88
x + 55 = 88
x + 55 - 55 = 88 - 55
x = 33
PLEASE HELP !! WILL MARK BRAINLIEST !!!
Answer:
5
Step-by-step explanation:
We can write the equation 7y=3y+20, because the top and bottom lemgths are equivalent
Now isolate x:
7y=3y+20
7y-3y=3y+20-3y (subtract 3y, subtraction property of equality)
7y-3y=20
4y=20 (simplify)
4y/4=20/4 (divide by 4, division property if equality)
y=5

triangle area ?
Answer:
A= 21.65063509
Step-by-step explanation:
triangle area is =base*hight/2
Because we have a right triangle we can apply the trigonometric functions
sin30 =base/hypothenuse = base/10
cos 30 = hight/hypothenuse =hight/10
sin30 = base /10 ; multiply both sides by 10
base = 10*sin30
cos 30 = hight /10 ; multiply both sides by 10
hight = 10 cos 30
A= 10*sin30*10*cos30/2 =
100*sin 30*cos 30/2=
50*sin30*cos30 = ; use calculator make sure is set up in degrees
A= 21.65063509

in the parallelogram shown, find x in terms of u and v.
Answer:
x = 2u -v
Step-by-step explanation:
X is the excess when we try to squeeze 2 u's on the side v,therefore
x = 2u -v
The value of x in terms of u and v is √(u²/2 + v²/2).
The parallelogram shown is a rhombus, so all four sides are congruent. This means that the sides labeled u and v are congruent. Since the opposite sides of a parallelogram are equal, the sides labeled u and v are also parallel.
The diagonals of a rhombus bisect each other at right angles. This means that the angles formed by the diagonals are 90°.
The diagonals of a rhombus also divide the rhombus into four congruent right triangles. This means that the triangles labeled 1, 2, 3, and 4 are all congruent.
We can use the Pythagorean theorem to find the length of x. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, the hypotenuse is x, so the square of the hypotenuse is x². The other two sides are u/2 and v/2. The square of each side is u²/4 and v²/4. Therefore, we can write the following equation:
x² = u²/4 + v²/4
Solve for x:
x² = u²/2 + v²/2
x = √(u²/2 + v²/2)
Therefore, x is equal to √(u²/2 + v²/2).

you find an apartment on Craigslist that is advertised as having an area of 700 square feet. How big is the apartment in square yards? Round to the nearest tenths place. (5 pts) Hint: I yd 3 ft 1 yd 3 ft
Answer:
x = 77.8 square yards
Step-by-step explanation:
Given the following data;
Area = 700 square feet
To find the area in square yards;
Conversion:
1 yard = 3 feet
1 square yard = 9 square feet
x square yard = 700 square feet
Cross-multiplying, we have;
700 = 9x
x = 700/9
x = 77.8 square yards
Tessellations (image below)
9514 1404 393
Answer:
regular octagon
Step-by-step explanation:
In order for a shape to tessellate a plane, there must be a way to arrange the shapes so that the sum of angles at a node is 360°. An arrangement of kites is shown in the attachment. Of course, squares are used to tile planes all the time, as their four 90° corners fit together nicely.
An octagon has internal angles of 135°, which is not a sub-multiple of 360°. Hence there is no way for octagons to fit together to tile a plane.
Octagons will not tessellate a plane.
find the value of x and y in the parallelogram
Answer:
x=14

Use the formula for simple interest to help solve the following questions
Answer:
1. ₹ 382.50
2. ₹ 14,583.33
3. 6%
Step-by-step explanation:
Interest = p × r × t
p = principal amount
r = rate of interest
t = time in years
(1) Interest = 10,200 × 0.025 × 1.5
= ₹ 382.50
(2) Principal = [tex]\frac{I}{(r\times t)}[/tex]
= [tex]\frac{1750}{(0.04 \times 3)}[/tex]
= [tex]\frac{1750}{0.12}[/tex]
