Answer:
Each dimension increased by 3 ft.
Step-by-step explanation:
Area of the original rectangle = 4 * 6 = 24 square feet
Increased dimension = x ft
New length = 6 + x
New width = 4 +x
New area = (6 + x)(4 +x) {Use FOIL method}
= 6*4 + 6*x + x*4 + x*x
= 24 + 6x + 4x + x²
= x² + 10x + 24
New area = 24 + 39
x² + 10x + 24 = 63
x² +10x + 24 - 63 = 0
x² + 10x - 39 = 0
x² + 13x - 3x - 3*13 = 0
x (x + 13) - 3(x + 13) = 0
(x + 13)(x -3) = 0 {Ignore x + 13, as it gives negative value}
x - 3 = 0
x = 3
find x and y plz help :(
Answer:
D. x = 5.4, y = 6.67
Step-by-step explanation:
The triangles are similar as per problem description, so the ratios match:
y/5 = 4/3
x/3 = 9/5
let's solve:
y/5 = 4/3
3y/5 = 4
3y = 20
y = 6.(6)
x/3 = 9/5
5x/3 = 9
5x = 27
x = 5.4

Answer:
Option B (the pentagonal pyramid)
Step-by-step explanation:
Given the pentagram, we can see a pentagon in the middle. The pentagonal prism (option A) and pentagonal pyramid (option B) both have bases of a pentagon. However, their nets are different. Only the pentagonal pyramid's net is that of a pentagram. Therefore, option B is correct.

Answer:
74.6
Step-by-step explanation:
The area of the given triangle in the image is 74.8m².
What is a triangle?A triangle is simply a polygon with three vertices with three edges.
A scalene triangle is the triangle with no equal sides and angles.
It area can be calculated using the expression;
A = 1/2 × absinθ
Given the data in question;
Length of side a = 15mLength of side b = 11mLength of side c = 22mAngle C = 115°
To determine the area of the triangle, we substitute our given values into the expression above.
A = 1/2 × absinθ
A = 1/2 × 15m × 11m × sin( 115° )
A = 0.5 × 15m × 11m × 0.9063
A = 74.76975m²
A = 74.8m²
Therefore, the area of the given triangle in the image is 74.8m²

What is the Y-Intercept of this table?
[tex]\left[\begin{array}{ccc}x&y\\5&16\\6&19\\7&22\end{array}\right][/tex]
Answer:
The Y-intercept is 4 or (0,4) in a plot
Step-by-step explanation:
To find the Y-intercept you need to make the "x" zero so if you move 5 to 4 in the "x" plot you need to move 16 to 13
(Since 22 to 19 is -3 19 to 16 is -3 as well it is safe to say that the next number is 13)
Now continue until you reach 0 in the "x"
4 to 3 and 13 to 10
3 to 2 and 10 to 7
2 to 1 and 7 to 4
So the y-intercept is 4 or (0,4) in a plot

Lupe and her friends spent $20 on snack mix and water. They bought x bags of snack mix and y bottles of water. They bought a total of 11 items. How many bags of snack mix did they buy?
Answer:
6 bags of snack mix
Step-by-step explanation:
x bags of snack mix
y bottles of water
The equations in the question is given as;
20.00 = 2.50x + 1.00y (i)
11 = x + y (ii)
From eqn (ii);
11 - y = x
substitute the value of x in eqn (i);
20.00 = 2.50(11 - y) + 1.00y
20.00 = 27.5 - 2.50y + 1.00y
20.00 - 27.5 = - 1.50 y
- 7.5 = - 1.50 y
y = - 7.5 / (- 1.5) = 5
Since we are interested in the value of x. Substitute the value of y in eqn (ii);
11 = x + 5
x = 11 - 5 = 6
Geometry please help-
If HI and JI are tangent segments, what is the measure of angle HJI?
Answer:
68°
Step-by-step explanation:
We can find this by remembering that tangents meet a circle at a ninety degree angle with the diameter or a radius that touches the point of intersection. By understanding that because these two tangents intersect at a point outside the circle there angle measure is the same so we can use the 180° total in a triangle to find the remaining degrees to be divided into the two measures we need to find. Because 180 - 48 equals 132 we divide this by 2 to get our angle measure of 68 degrees.

Work out the size of angle x.
(4)
Answer:
x = 46°
Step-by-step explanation:
Since Δ ABC is equilateral then interior angles = 60°
Since CE = DE then Δ CDE is isosceles and the base angles are congruent, so
∠ ECD = [tex]\frac{180-32}{2}[/tex] = [tex]\frac{148}{2}[/tex] = 74°
BCD is a straight line, then the 3 angles on it sum to 180°, that is
60° + 74° + x = 180°
134° + x = 180° ( subtract 134° from both sides )
x = 46°
Solve for X. Please help ASAP! I have no idea how to do this and it’s due really soon!

108 divided by 2 1/2
Answer:
43.2
Step-by-step explanation:
first turn 2 1/2 into an improper fraction
(2 × 2) + 1 = 5
5/2
then turn 5/2 into a fraction
5 ÷ 2 = 2.5
now divide!
108 ÷ 2.5 = 43.2
Number equivalent to 108/2 1/2 is 43.2 .
Given,
108 divided 2 1/2
Using division property,
The rules for division are:
(1) positive × or ÷ positive = positive
(2) positive × or ÷ negative = negative
(3) negative × or ÷ negative = positive
Rule for long division method,
Divide the tens column dividend by the divisor.
Multiply the divisor by the quotient in the tens place column.
Subtract the product from the divisor.
Bring down the dividend in the ones column and repeat.
Therefore,
divide, multiply, subtract, bring down and repeat or find the remainder.
Here the required value is of :
108/2 1/2
= 108 / (5/2)
= 43.2
Hence the answer is 43.2
