Answer:
x = 12.5
Step-by-step explanation:
The three sides of the triangle have lengths 3x, 3x, and 15.
The perimeter of the triangle is the sum of the three lengths, and it is 90.
Perimeter = 3x + 3x + 15 = 6x + 15
3x + 3x + 15 = 90
6x + 15 = 90
6x = 75
x = 12.5
Will Give Brainy ( Geometry) look at picture please
Answer:
x=12 , y= 49
Step-by-step explanation:
X= 180 - (90+78)= 12
180-(90+41)= 49
y=49 (isosceles triangle)
what fraction of 7 2/5 is 49 1/3?
Answer:
8 1/6 / 1 7/8 = 196/45 = 4 16/45 ≅ 4.3555556
Step-by-step explanation:
Conversion a mixed number 8 1/6
to a improper fraction: 8 1/6 = 8 1/6 = 8 · 6 + 1/6= 48 + 1/6 = 49/6
To find new numerator:
a) Multiply the whole number 8 by the denominator 6. Whole number 8 equally 8 * 6/6 = 48/6
b) Add the answer from previous step 48 to the numerator 1. New numerator is 48 + 1 = 49
c) Write a previous answer (new numerator 49) over the denominator 6.
Eight and one sixth is forty-nine sixths
Conversion a mixed number 1 7/8
to a improper fraction: 1 7/8 = 1 7/8 = 1 · 8 + 7/8 = 8 + 7/8= 15/8
To find new numerator:
a) Multiply the whole number 1 by the denominator 8. Whole number 1 equally 1 * 8/8 = 8/8
b) Add the answer from previous step 8 to the numerator 7. New numerator is 8 + 7 = 15
c) Write a previous answer (new numerator 15) over the denominator 8.
One and seven eighths is fifteen eighths
Divide: 49/6 : 15/8 = 49/6 · 8/15 = 49 · 8/6 · 15 = 392/90 = 2 · 196 /2 · 45 = 196/45
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 15/
8 is 8/15
) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 2 gives 196/45
.
In words - forty-nine sixths divided by fifteen eighths = one hundred ninety-six forty-fifths.

My other dog, Beau, runs through the house dropping a line of slobber across
my 40 foot hallway. If he runs at a rate of 15 ftis, how long did it take him to mess
Answer:
2.67 seconds
Step-by-step explanation:
Distance covered by the dog = 40 ft
The rate at which the dog runs (speed) = 15 ft/s
But,
speed = [tex]\frac{distance}{time}[/tex]
So that,
time = [tex]\frac{distance}{speed}[/tex]
= [tex]\frac{40}{15}[/tex]
= 2[tex]\frac{2}{3}[/tex]
time = 2.6667 s
It would take the dog 2.67 s to mess.

Triangle XYZ is reflected across the y-axis, and X = (4, –5). What are the coordinates of X’ ?
(–5, 4)
(–4, –5)
(4, 5)
(–4, 5)
Answer:B
Step-by-step explanation:I looked it up, I don’t copy people’s answers ok don’t flame me in comments.
The coordinates of X in triangle XYZ after reflection across the y axis is X' = (-4, -5)
TransformationTransformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation
If a point A(x, y) is reflected over the line y axis, the new point is at A'(-x, y).
Triangle XYZ is reflected across the y-axis, and X = (4, –5). Hence X' = (-4, -5)

Help a friend in need
a) 4.71ft
b) 3.53ft^2
Step-by-step explanation:
Perimeter is 1/2 the circumference
1/2 Circumference = 2*pi*radius
Radius = 1/2 Diameter
Radius = 3/2 = 1.5ft
Circumference = 2*pi*1.5ft = 9.42
1/2 Circumference = 4.71
4.71ft is the perimeter.
The area is 1/2 that of a full circle
A = pi*r^2
A = 3.14*1.5*1.5
A = 7.065ft^2
1/2 A = 3.53ft^2

Answer:

Step-by-step explanation:
hope u understand sorry for bad photo
Answer:
x = 9
Step-by-step explanation:
[tex] \triangle ABC\sim \triangle ADE.... (given) [/tex]
[tex] \therefore \frac{AB}{AD} = \frac{BC}{DE}.... (csst) [/tex]
[tex] \therefore \frac{28}{20} = \frac{2x+3}{15}[/tex]
[tex] \therefore \frac{7}{5} = \frac{2x+3}{15}[/tex]
[tex] 5(2x+3) = 7\times 15[/tex]
[tex] 10x+15 = 105[/tex]
[tex] 10x = 105-15[/tex]
[tex] 10x = 90[/tex]
[tex] x = \frac {90}{10}[/tex]

Which graph shows the solution set of x2 + 9x + 20 / x2 - x -20 > 0 ?
Answer:
B Is correct
Step-by-step explanation:
Solve the solution set and divide to get the points and whether to fill them in or not.
-5 filled in, and 5 open circle
The graph of the solution set can be seen in option B.
What is a solution set?
The solution set is the set representing all solutions for an equation. It is also the roots that obey a quadratic equation or an inequality.
From the given equation, we have:
[tex]\mathbf{\dfrac{x^2+9x+20}{x^2-x-20}\ge 0}[/tex]
Let's factor out the quadratic equation, we have:
[tex]\mathbf{\dfrac{(x+4)(x+5)}{(x+4)(x-5)}\ge 0}[/tex]
By identifying the intervals;
x ≤ -5 or x > 5
The representation of these intervals on a graduated scale on a number line can be seen in the image attached below.
Therefore, we can conclude that the correct graph that show the solution set to the given equation can be seen in Option B.

How much paint is needed to paint a house ? Estimate or exact
Answer:
One gallon can of paint will cover up to 400 square feet, which is enough to cover a small room like a bathroom. Two gallon cans of paint cover up to 800 square feet, which is enough to cover an average size room. This is the most common amount needed, especially when considering second coat coverage.
Step-by-step explanation:
Answer:
well it depends on how big the house so... One gallon can of paint will cover up to 400 square feet, which is enough to cover a small room like a bathroom. Two gallon cans of paint cover up to 800 square feet, which is enough to cover an average size room. so about 2 maybe 3 gallons
