Step-by-step explanation:
3(0.5x-4)=3/2x-1.2
We simplify the equation to the form, which is simple to understand
3(0.5x-4)=3/2x-1.2
Reorder the terms in parentheses
+(+1.5x-12)=/2x-1.2
Reorder the terms in parentheses
We move all terms containing x to the left and all other terms to the right.
0=0
We simplify left and right side of the equation.
0=0
0=0
This equation is an identity, so all real numbers are solutions.

2. Destiny rents games from a company that charges a $9.00 monthly fee and $2.50 for each game rental. She ends up paying $26.50 for the month of July. The equation 2.5x + 9 = 26.5 represents this situation. Solve the equation for x. What does this value of x mean in terms of the context?
Answer:
x = 7
and it means that 7 games were rented that month
Step-by-step explanation:
Here, we are to solve for x from the given equation
we have this as:
2.5x + 9 = 26.5
2.5x = 26.5-9
2.5x = 17.5
x = 17.5/2.5
x = 7
What x means in this case is that the number of games rented in the month is 7

what's the question you can't just give a sentence
find the equivalent rate:
1550 calories/2.5 hours = ? calories/ 1 day
Answer:
14880 calories /24 hours
Step-by-step explanation:
one of the fraction has hours the others day so you have to convert to make them the same 1day =24 hours
[tex]\frac{1550 calories}{2.5 hours} =\frac{? calories }{24 hours}[/tex]
you have two fractions that are equal so you can cross multiply
24*1550 = ? * 2.5 ; divide both sides by 2.5
37200/2.5 = ?
? = 14880 calories
the equivalent rate is :
[tex]\frac{1550 calories}{2.5 hours} = \frac{14880 calories}{24 hours}[/tex]

1. Given a right triangle ABC, find the following trigonometric ratios with sides AB = 6, BC = 8 and AC = 10 units. Hint: draw and label your triangle.
a) sin A = 0.13
b) cos A = 0.99
c) tan A = 0.02
d) sin C = 0.01
e) cos C = 0.99
2. Looking back at question 1,
a) which vertex has the right angle? How do you know? B has a vertex. I know this because angle A and and C connect to angle B, and angle B it the corner of a right angle.
b) what do you notice about sine and cosine of complementary angles? The sine of A is different from the sine of C, and the Cosine of A is the same as the cosine of C
Answer:
Q1.
AC is the greatest side, therefore is hypotenuse. AB and BC are legs.
B is 90 deg as the two legs cross at this point.
Ratios:
sin = opposite / hypotenusecos = adjacent / hypotenusetan = opposite / adjacentBC is opposite to A and adjacent to C
AB is adjacent to A and opposite to C
sin A = cos C = 8/10 = 4/5cos A = sin C = 6/10 = 3/5tan A = cot C = 8/6 = 4/3tan C = cot A = 6/8 = 3/4Q2.

A right rectangular pyramid is sloed vertically (down) at the red line by a
plane not passing through the vertex of the pyramid. What is the shape of the
cross-section?
A. Triangle
B. cylinder
C. Trapezoid
D. Rectangle
The correct answer is C. Trapezoid.
What is a Trapezoid?A trapezoid is a quadrilateral with at least one pair of parallel sides. It can have two parallel sides (a "parallel trapezoid") or none (a "non-parallel trapezoid").
The shape of the cross-section will depend on the orientation of the plane with respect to the pyramid. However, since the plane does not pass through the vertex of the pyramid, we know that the cross-section will not be a point or a line.
Assuming that the plane intersects all four triangular faces of the pyramid, the shape of the cross-section will be a trapezoid. Specifically, it will be a trapezoid with one pair of parallel sides (the bases) and two non-parallel sides (the legs) that meet at a common vertex.
Therefore, the correct answer is C. Trapezoid.

Two sides of a rectangle are 10 and 6cm each. Calculate the area of a square with the same perimeter as that of the rectangle
Answer: 64 cm ²
Step-by-step explanation:
The perimeter of this rectangle will be:
= 2 * Length + 2 * Width
= 2 * 10 + 2 * 6
= 20 + 12
= 32 cm
The square has the same perimeter. Squares have 4 equal sides so each side of the square must be:
= 32 / 4
= 8 cm
Area = Length * Width
= 8 * 8
= 64 cm ²

The Diagram shows a triangle inside a circle woth center O. the lengyhs of the shorter sides of the triangle are 12 cm and 16 cm. work out the area of the circle
Step-by-step explanation:
using pythagorean theorem:
c^2=a^2+b^2
16^2=a^2+12^2
16^2-12^2=a^2
256-144=a^2
[tex] \sqrt{112 = a {}^{2} } [/tex]
10.5=a.(which is the diametre of the circle)
area of cirlcle=
[tex]pir {}^{2} [/tex]
=3.14×5.25^2
area=86.3
The area of the circle will be 87.91 cm² in the given figure.
What is the area of the circle?The area of the circle is equal to the product of the square of the radius of the circle and pi.
A = πr²
where 'r' is the radius of the circle
The given figure represents a triangle inside a circle with a center O.
As per the given figure,
The lengths of the shorter sides of the triangle are 12 cm and 16 cm.
The triangle is given in the figure is the right triangle.
According to Pythagoras's theorem,
⇒ c² = a² + b²
Here c = 16 and b = 12
⇒ 16² = a² + 12²
⇒ 16² - 12² = a²
⇒ 256 - 144 = a²
⇒ a² = 112
⇒ a = √112
⇒ a = 10.58 cm
The diameter of the circle = a = 10.58 cm
The area of the circle = π × (a/2)² = π × (10.58/2)²
The area of the circle = 87.91 cm²
Therefore, the area of the circle will be 87.91 cm² in the given figure.
