I’m rohmbus ABCD, AB= 14 and AC= 26. Find the area of the rhombus to the nearest tenth.
Answers
we know
In a rhombus ABCD , AC = 26 , AB = 14
the diagonals of a rhombus are perpendicular bisectors of each other
AX = XC = 13. triangle ABX is a right triangle with hypotenuse 14.
From the pythagoras theorem AB² = AX² + BX²
14² = 13² + BX²
196 = 169 + BX²
27 = BX²----- > BX=√27
BX = 5.20
The four triangles formed by construction of the diagonals are all congruent since the diagonals are perpendicular bisectors.
Total area of the rhombus is 4 times of ABX triangle
the answer is the option D) 135.1 units ²

the main span of the sunshine skyway bridge is 360 meters long. The skyway’s main span is 30 meters shorter than the main span of the dames point bridge. write and solve an equation to find the length of the main span of the dames point bridge
Answers
360 = x - 30
To solve for x, we must do the opposite of the operation we see. The opposite of subtracting 30 is adding 30. So we must add 30 to both sides of our equation.
360 + 30 = 390
So,
x = 390
This means that the length of the main span of the dames point bridge is 390 meters.

100 children attended a play on the trip 0.6 were girls. Which fraction represents the number of boys on the trip
Answers
Hope this helped!
The number of boys who attended the play is 40. Expressing this as a fraction of the total children (100), we get 40/100, which simplifies to 2/5. So, the fraction representing the number of boys on the trip is 2/5.
Explanation:The provided information suggests that 60% (or 0.6) of the children on the trip, which were 100, were girls. This means the percentage or portion of girls on the trip is 0.6*100 = 60 girls. Since we're looking for the number of boys, we have to subtract this figure from the total number of children.
So, 100 total children - 60 girls = 40 boys. To express this as a fraction of the total number of children, we get 40/100. This fraction, however, can be simplified to 2/5, which is the fraction that represents the number of boys on the trip.

Suppose a small airplane has a wingspan of 15 feet. Find the wingspan of a model of the airplane, in inches, if the scale factor is 1 60 .
Answers
Solution:
we are given that
Airplane has a wingspan of 15 feet.
we have been asked to find the wingspan of a model of the airplane, in inches, if the scale factor is 1:60 .
It mean for each one unit of original wingspan we are supposed to have [tex]\frac{1}{60}th[/tex] times the wingspan of model airplane.
Here the original airplane has a wingspan of 15 feet. So the model airplane has a wingspan of [tex]\frac{1}{60}*15=\frac{1}{4} ft[/tex]
Since one fit=12 inches So we can say
[tex] \frac{1}{4} ft=\frac{12}{4} inches=3 inches.[/tex]
Hence the model airplane has a wingspan of 3 inches.

how to unfoil quickly try not to use a lot of steps.
Answers
take out: x²(x+4)-9(x+4)
take out (x+4): (x+4)(x²-9)
factor again: (x+4)(x+3)(x-3)
Final answer:
To unfoil quickly, use the reverse foil method. Identify the first and last terms of each binomial, multiply them, and rewrite the middle term as the sum of the products. Example: (x + 2)(x - 3) = x^2 + 2x - 3x - 6.
Explanation:
To unfoil quickly, you can use a shortcut called the reverse foil method. Reverse foil allows you to quickly determine the original factors of a quadratic expression that has been expanded using the distributive property. Let's say we have the expression (x + 2)(x - 3) and we want to unfoil it. Start by identifying the first term of each binomial, which in this case is x from (x + 2) and x from (x - 3). Multiply these two terms together to get x^2. Then, identify the last term of each binomial, which is 2 from (x + 2) and -3 from (x - 3). Multiply these two terms together to get -6. Finally, rewrite the middle term of the expanded expression as the sum of the two products obtained: (x^2 + 2x - 3x - 6). In this way, you can unfoil the expression quickly and identify the original factors without having to expand it fully.

Calculate the area of a circle with a diameter of 6cm
Answers
A=πr²
Here diameter, d= 6 cm
Radius, r= d/2 = 6/2 = 3 cm
Put values
A= 3.14 x 3²
A=3.14 x 9
A=28.26 cm²
Answer: 28.26 cm²
We'll do it in terms of Pi, as a variable, and in terms of pi as 3.14
We know that since the diameter is from one side to the other in a circle, dividing it by 2 will give you the radius - the distance to the middle. We plug in this radius to our area formula:
a = [tex] \pi (r^2)[/tex]
a = [tex] \pi (3^2)[/tex]
a = 9[tex] \pi [/tex]
If our area is 9 pi, we can multiply 9 by 3.14 to get an approximate value:
A = 3.14(9)
A = 28.26
Hope this helps!

Which of the following is the inequality −18x + 2y ≥ −13 written in slope-intercept form?
Select one:
A. y ≥ - 6.5x - 9
B. y ≥ 7x - 10
C. y ≥ 9x − 6.5
D. y ≥ 10x - 7
Answers
We're simply just trying to convert "-18x + 2y ≥ -13" into slope-intercept form.
First, we need to know what slope-intercept form is.
Slope-intercept form is : y=mx+b , where m=slope and b=y-intercept.
In order to convert our given equation into slope-intercept form, we have to isolate "y."
We can do this by adding 18x to both sides.
2y ≥ 18x - 13
Then, divide both sides by 2.
2y ÷ 2 = (18x - 13) ÷ 2
Simplify.
y = 9x - 13/2
Convert -13/2 into a mixed fraction.
So, simply divide -13 by 2.
-13 ÷ 2 = -6.5
Plug in -6.5 into where -13/2 was.
y = 9x - 6.5
Therefore, your answer is C : y ≥ 9x - 6.5

What measurements of a cone can be found if you know the volume and height? Explain how to apply the formula.
Answers
Answer:
The base area , radius, and diameter can be determined when given the volume and height of a cone. Substitute the values for the corresponding variables into the formula, and then solve by simplifying and undoing operations to isolate the variable. To find the diameter, double the radius.
Step-by-step explanation:
The formula for the cone is [tex]\frac{1}{3} \pi r^2 h[/tex]. The cone is a three-dimensional geometric object with a circular base that tapers to a point called the vertex from a flat base.
What is a cone?It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.
The volume of a cone is;
[tex]\rm V = \frac{1}{3} \pi r^2 h[/tex]
Where
h is the height of the cone
r is the radius
V is the volume
Hence the formula for the cone is [tex]\frac{1}{3} \pi r^2 h[/tex]

Find the system determinant of the given matrix.

Answers
The determinant of 2 x 2 matrix can be calculated as follows:
1) Multiply the main diagonal elements.
The main diagonal elements are 2 and -9. Multiplying them we get -18
2) Multiply the remaining two elements (Non diagonal elements)
The other two elements are 3 and 4. Multiplying them we get 12.
3) Subtract the product of non diagonal elements from the product of diagonal elements, this will give the determinant of the matrix.
So, determinant will be = -18 - 12 = -30
In one step, this can be done directly as:
Determinant = 2(-9) - 3(4) = - 30
