(10-x)(3x -9)=0
NEED HELP ASAP
Answers
Answer:
Step-by-step explanation:
Since the expressions are multiplied, for the product to equal zero, one term or another has to equal 0 because 0 times anything is zero.
(10-x)(3x-9)=0 when
10-x=0, x=10
3x-9=0, x=9/3=3
So there are two solutions when x=3 and x=10

135°Step-by-step explanation:
This is a cyclic quadrilateral.
It has a property of opposite angles being supplementary.
A and C are supplementary angles:
3x + 6 + x + 2 = 1804x + 8 = 1804x = 172x = 43m∠A = 3x + 6 = 3*43+ 6 = 135°
Answer:
<A=135°
Step-by-step explanation:
3x+6+x+2=180
sum of two opposite angle of the cyclic quadrilateral is 180
4x=180-8
x=172/4=43°
<A=3×43+6=135° is your answer
Rick bought a car for $17,500. Each year, the car's value decreases by 20%. At this rate, what can Rick expect the value of his car to be in 6 years? *

$4,587.52
$17,380.00
Answers
Answer:
His car would be worth $15,502.24
Step-by-step explanation:
20% of 17,500 is 350. 350 x 6 = 2,100. 17,500 - 2,100 = 15,400. But that is not an answer choice so be go to the closest number which is $15,502.24

1/18 mile
2/9 mile
4 1/5 miles
4 1/2 miles
Answers
Answer:
4 1/2
Step-by-step explanation:
The origional question is ¨A turtle travels 1/2 mile in 1/9 hour. At this rate, how far can the turtle travel in an hour¨ To be honest i have no clue how to explain it but that is the awanser.
The turtle will travel [tex]4\frac{1}{2}[/tex] in an hour.
What is proportion?A proportion is an equation in which two ratios are set equal to each other.
Given that, a turtle travels 1/2 mile in 1/9 hour. we need to find, at this rate, how far can the turtle travel in an hour.
We will solve this by using proportionality, since, rate is constant,
Let the turtle travels x miles in an hour,
Therefore,
x / 1 = (1/2) / (1/9)
x = 1/2 × 9
x = 9/2
x = [tex]4\frac{1}{2}[/tex]
Hence, the turtle will travel [tex]4\frac{1}{2}[/tex] in an hour.

Answers
for the ball to get to the ground the h=0 no hight it is now in the base point.
substitute the value t=0 into the equation we get 64.
since we want to know the time in seconds then we should subtract 60 from 64 (64-60=4)
then my answer is 0-4.

Why is the surface area of a triangular prism measured in square units rather than in cubic units? Surface area measures the area of the faces. Area is a -dimensional measurement, so it is measured in square units.
Answers
Answer:
Step-by-step explanation:
Area of a given figure is a 2 dimensional measurement which describes the amount of space occupied by the figure, while volume of the figure describes its capacity in a 3 dimensional measurement.
The surface area of a triangular prism is the sum of the areas of all its surfaces. Since the surface area considers the areas of the figure not volume, therefore the surface area of the triangular prism is measured in square units not cubic units.

Answers
The size of the angle 'x' is 117°
The external angle of a triangle:An external angle of a triangle is an angle formed by extending one side of the triangle and intersecting with the extension of another side.
In a triangle, the measure of an external angle is equal to the sum of the measures of the two opposite interior angles.
Here we have a triangle
Let the ABC be the triangle as given in the picture
=> ∠A = 38°
From the baseline BC
=> Measure of B = 180° - 101° = 79°
As we know
In a triangle, the measure of an external angle is equal to the sum of the two opposite interior angles
=> x = ∠A + ∠C
=> x = 38° + 79°
=> x = 117°
Therefore,
The size of the angle 'x' is 117°

The sum of two numbers is 8. Two times the larger number plus four times the smaller number is 8. Find the numbers.
Answers
Answer: 12 and -4
Step-by-step explanation:
Assume the larger number is x and the smaller one is y.
In that case the relevant simultaneous equations are:
x + y = 8
2x + 4y = 8
Use substitution to find relative value of y:
x + y = 8
y = 8 - x
Use to solve equation:
2x + 4y = 8
2x + 4(8 - x) = 8
2x + 32 - 4x = 8
2x - 4x= 8 - 32
-2x = -24
x = -24 / -2
x = 12
y = 8 - x
= 8 - 12
