Answer:The equation wth x in the information can be written as
1/2 x = 38.5 , Upon solving, the number = 77
Step-by-step explanation:
Let the number Sara was thinking about be x
halving the number to get an answer = 38.5 can be expressed as
1/2 X = 38.5
The equation with x in the information can be written as
1/2 x = 38.5
solving it becomes
1/2 x= 38.5
x = 38.5 x 2
x=77
The number Sara was thinking about = 77
What would Hope be attempting to find if she writes d(4) = 78(4)?
Answer:
d=78
Step-by-step explanation:
so you would divide both sides of the equation by 2×2
d×4÷(2×2)=78×4÷(2×2) <- you would do this to get rid of 4 so you cna get the d alone
d=78×4÷(2×2) <- thats the other side of the equation btw
then it would be:
d=39×2
d=78
Two rectangular prisms have the same volume. The area of the base, B, of the blue prism is 418 square units. The area of the base, B, of the red prism is half that of the blue prism. Which statement is true? A rectangular prism with side length h. B = 4 and one-eighth square units. The base of the prism. B = one-half times (4 and one-eighth square units).
Answer:
The height of the blue prism is half the height of the red prism
Step-by-step explanation:
Represent the volume of the blue prism with Vb and the red prism with Vr
So, we have:
[tex]V_r = V_b[/tex]
[tex]A_b = 418[/tex] --- base area of the blue
[tex]A_r = \frac{1}{2}A_b[/tex] --- base area of the red
Required
Determine which statement about the heights of the prisms is true
Volume is calculated as:
[tex]Volume = Base\ Area * Height[/tex]
For the blue prism:
[tex]V_b = A_b * h_b[/tex]
For the red prism
[tex]V_r = A_r * h_r[/tex]
Equate both volumes
[tex]V_r = V_b[/tex]
[tex]A_r * h_r = A_b * h_b[/tex]
Substitute the expression for [tex]A_r[/tex]
[tex]\frac{1}{2}A_b * h_r = A_b * h_b[/tex]
Divide both sides by [tex]A_b[/tex]
[tex]\frac{1}{2} h_r = h_b[/tex]
This implies that the height of the blue prism is half the height of the red prism

3 A Gas station A charges $3.50 per gallon of gas plus 58 for a car wash. Gas station B charges $3.25 per gallon of gas plus S10 for a car wash. How many gallons of gas must a customer purchase for the total cost to be the same at both gas stations?
9514 1404 393
Answer:
8 gallons
Step-by-step explanation:
The $2 difference in the price of a car wash is made up by the gas purchase at the rate of $0.25 per gallon. So, it takes ...
$2/($0.25/gal) = 8 gal
to make the costs the same.
The customer must purchase 8 gallons for the total cost to be the same at both gas stations.
___
3.50g +8 = 3.25g +10 . . . . costs at each station for g gallons of gas + wash
0.25g = 2 . . . . . . . . . subtract 3.25g+8 from both sides
g = 2/.25 = 8 . . . . . . the way we did it above

please show the work, i’ll mark brainliest
Answer:
47
Step-by-step explanation:
Let's solve your equation step-by-step.
−4x−3(−44−23)=13
Step 1: Simplify both sides of the equation.
−4x+201=13
Step 2: Subtract 201 from both sides.
−4x+201−201=13−201
−4x=−188
Step 3: Divide both sides by -4.
−4x
−4
=
−188

What is AC for brainliest
•Triangle 1
#Find CD first use tan formula
tan(∅) = opposite / adjuscent
tan(45) = CD / 5
CD = 5 × tan(45)
CD = 5
•Triangle 2
#Now you can find AC use Pythagoras theorem (c = AC)
a² + b² = c²
4² + 5² = c²
16 + 25 = c²
41 = c²
c = √41
c = 6.4
so, AC is 6.4

(67.2 - 32) /67.2 = x / 81.9
35.2 / 67.2 = x / 81.9
Cross Multiply
67.2 * x = 81.9 * 35.2
67.2 x = 2882.88
Divide by 67.2
x = 2882.88 / 67.2
x = 42.9

the root of equation 1/x-1 +1/x-2 = 1/x-3
Answer:
The roots of the quadratic equation are , .
Step-by-step explanation:
The roots of the quadratic equation are , .
Step-by-step explanation:
As given the equation in the form
Simplify the above equation
(x-2)-x = 3x × (x-2)
x-2 - x = 3x² - 6x
3x² - 6x + 2 = 0
As the equation is written in the form ax² + bx + c = 0
a = 3 , b = -6 , c = 2
Put all the values in the above equation
Thus
Therefore the roots of the quadratic equation are , .
Select all line segment measurements below that could NOT be used to form a triangle. a triangle with the side measurements of 3, 4, and 6 inches a triangle with the side measurements of 2, 3, and 5 inches a triangle with the side measurements of 3, 3, and 4 inches a triangle with the side measurements of 5, 5, and 5 inches a triangle with the side measurements of 4, 4, and 8 inches a triangle with the side measurements of 7, 8, and 16 inches
Answer:
a triangle with the side measurements of 2, 3, and 5 inches
a triangle with the side measurements of 7, 8, and 16 inches
a triangle with the side measurements of 4, 4, and 8 inches
Step-by-step explanation:
A triangle is a polygon shape with three sides and three angles. There are different types of triangles such as isosceles triangle, scalene triangle, equilateral triangle and right angle triangle.
The triangle inequality theorem states that the sum of any two sides of a triangle is always greater than the third side.
For a triangle with the side measurements of 3, 4, and 6 inches:
3 + 4 > 6. This can be a triangle
For a triangle with the side measurements of 2, 3, and 5 inches:
2 + 3 is not greater than 5, hence it cannot be a triangle
For a triangle with the side measurements of 3, 3, and 4 inches:
3 + 3 > 4. This can be a triangle
For a triangle with the side measurements of 5, 5, and 5 inches
5 + 5 > 5. This can be a triangle
For a triangle with the side measurements of 4, 4, and 8 inches:
4 + 4 is not greater than 8, hence it cannot be a triangle
For a triangle with the side measurements of 7, 8, and 16 inches:
7 + 8 is not greater than 16, hence it cannot be a triangle

Leah has meters of cloth, which she divides equally among her friends. Each friend gets meters of cloth.
Answer: 6
Step-by-step explanation:
Here's the complete question:
Leah has 8 4/7 meters of cloth, which she divides equally among her friends. Each friend 10/7 gets meters of cloth. She distributed the cloth to ---- friends.
Total length of the cloth = 8 4/7m
Number of friends = Unknown
Amount of length gotten by each friend= 10/7
The number of friends that she shred the cloth among will be:
= Total length of cloth / Length gotten by each friend
= 8 4/7 ÷ 10/7
= 60/7 ÷ 10/7
= 6/7 × 7/10.
= 60/10

Answer:
6/4
Step-by-step explanation:
ratio of x to y is the slope so
you can use butterfly method/cross multiply (multiply numerator on one side to the denominator on the other to bring all the terms up and then solve for y)
4(y+3)=6(x+2)
4y+12=6x+12
y=6/4x
so it would be 6/4
