Answer: 6.25.
Step-by-step explanation:
Let's put your question into a proper proportional form, because it is a ratio that is equal.
[tex]\frac{5}{12} = \frac{x}{15}[/tex]
To solve proportions, you have to cross-multiply in the direction that has numbers, which is 5 and 15, then divide to 12.
[tex]5 * 15 / 12 = 6.25[/tex]
The answer you should get by doing this is 6.25.
Answer:
x=6.25
Step-by-step explanation:
Cross multiply
5/12=x/15
12*x=15*5
12x=75
Divide both sides by 12 to isolate the variable x
x=6.25
Or, multiply both sides by 15 to "reverse" the division being done to x
5/12=x/15
15*5/12=x/15*15
6.25=x

What is the measure of angle b in degrees
Answer:
B=119
Step-by-step explanation:
C=180-112=68
68+51=119
A=180-119=61
180-61=119
B=119
Answer:
∠ B = 119°
Step-by-step explanation:
∠ C and 112° are adjacent angles and supplementary, thus
∠ C = 180° - 112° = 68°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ B is an exterior angle of the triangle, thus
∠ B = 51° + ∠ C = 51° + 68° = 119°

The square of a positive number increased by twice the number equals three. Find the number
Answer:
1
Step-by-step explanation:
Let the number be x
x² + 2x = 3
x² + 2x - 3 = 0
Product = -3
Sum =2
Factors = 3 * (-1)
x² + 3x - x - 3 = 0
x*(x+3) - (x + 3) = 0
(x + 3)(x - 1) = 0
Ignore x + 3 because the number is a positive number
x - 1 = 0
x = 1
The number is 1

In the square pyramid below, a = 12 ft and b = 10 ft.
What is the surface area of the square pyramid?
340 square feet
420 square feet
480 square feet
580 square feet
Square Pyramid
Hence , the surface area of the square pyramid is 340 square feet
Step-by-step explanation:
The square pyramid has a square base
Given that the base side is 10 ft and the slant height of the pyramid is 12 ft.
The surface area of a square pyramid is SA, then
SA = Area of the base + [tex]\frac{1}{2}[/tex] × P × Sh
where P is the perimeter of the base and Sh is the slant height of the pyramid
P = 4 × 10
SA = [tex]10^{2} + \frac{1}{2}[/tex]× 40 × 12
SA = 100 + 240
SA= 340 square feet
Hence , the surface area of the square pyramid is 340 square feet

How to factor a polynomial?In order to determine a solution for the given polynomial, we would factor it by using this quadratic form:
a² - b² = (a + b)(a - b)
4x² - 9 = 2x² - 3²
2x² - 3² = (2x + 3)(2x - 3)

Answer:
Madeline: y=1x+9
Issac: y=2x+1
x=8, y=17
Step-by-step explanation:
Solving for X:
Multiply Issac's by -1:
y= 1x+ 9
-y=-2x-1
Combine:
0=-x+8
Add x to both sides:
x=8
Solving for Y:
Since we already have x, we only need to input the x value into one of the formulas:
y=1(8)+9
Simplify parenthesis with multiplication:
y=8+9
Add:
y=17
If you feel unsure, check your work with both equations:
(17)=2(8)+1
17=16+1
17=17=Good
(17)=1(8)+9
17=8+9

2c + 5 = 11 + 4a
Factor then solve to find the complex solutions
c=2a+3
Answer:
c = 2a + 3
Step-by-step explanation:
2c + 5 = 11 + 4a
2c = 4a + 11 - 5
2c = 4a + 6
c = 4a/2 + 6/2
c = 2a + 3
A tent company makes one type of tent that is shaped like a triangular prism. The approximate dimensions are 5ft, 6ft, 9ft and 5.5ft. Based on these dimensions, how much fabric is needed to make one tent, including floor.
Given:
The base of the triangle = 6 ft
The height of the triangle = 5 ft
The other two side of the triangle = 5.5 ft and 5.5 ft
The height of the prism = 9 ft
To find the measurement of the fabric to make the tent.
We need to find the surface area of the triangular prism.
Formula
The surface area of the triangular prism is
[tex]SA = bh+(a+b+c)H[/tex]
where, b be the base of the triangle
h be the height of the triangle
a and c be other two sides of the triangle
H be the height of the prism
Now,
Putting,
b = 6, h = 5, a = 5.5, c = 5.5 and H = 9 we get,
[tex]SA = (5)(6)+(6+5.5+5.5)(9)[/tex] sq ft
or, [tex]SA = 30+153[/tex] sq ft
or, [tex]SA = 183[/tex] sq ft
Hence,
Based on the given dimension 183 sq ft fabric is needed to make the tent.

7.5
Answer:
a=4
Step-by-step explanation:
60=a(0+5)(0+3)
We can simplify this equation
60 = a (5) (3)
60 = a(15)
Divide each side by 15
60/15 = 15a/15
4 =a
Answer:
C) 4
Step-by-step explanation:
60=a(0+5)(0+3)
60 = a(5)(3)
60 = 15a
a = 60/15
a = 4

Clint found the area of the parallelogram shown. Which statement explains the error Clint made?
A parallelogram with a base of 11 centimeters, height of 4 centimeters, and side length of 5 centimeters.
Clint’s Work:
A = (b) (h). A = (11) (5). A = 55 centimeters squared.
a.Clint used the wrong units. He should have used cm, as that is what was in the diagram.
b.Clint used the wrong formula. He should have used A = one-half b h.
c.Clint did not use all three numbers in the diagram. He should have multiplied them all.
d.Clint did not use a height perpendicular to the base. He should have used 4 for the height.
Answer:
D
Step-by-step explanation:
like it said, he used 5 instead of the actual height which is 4
Answer:
D
Step-by-step explanation:
The area of a parallelogram is denoted by: [tex]A=bh[/tex] , where b is the base and h is the height that is perpendicular to the base. Depending on what kind of parallelogram it is (square, rectangle, rhombus, regular parallelogram), that height could be the side length, but usually it is not; it is only the side length in special cases, like a square.
Here, we are given that the base is 11 and that the height is 4. Since the problem gives us two different values for the height versus the side length, we know that for this parallelogram, the height is not the same as the side length. Thus, we must use 4 for the height and 11 for the base in the area formula.
Therefore, the only answer that correctly points out this mistake is D.
