In the diagram below of triangle DEF, G is a midpoint of DE and H is a midpoint
of EF. IfGH = 72 – 15, and DF = 38 – 3x, what is the measure of DF?
E
G
H
D
F
Answer:
GH= half of DF
so, 114= 38 - 3x
3x= 76
x= 76/ 3
find the slope of the line passing through the points (5, 6) and (5,-8)
Answer:
Undefined
Step-by-step explanation:
Slope is equal to the change in y over the change in x.
m = (y₂ - y₁) / (x₂ - x₁)
Let your points (5, 6) be (x₁, y₁) and (5,-8) be (x₂, y₂). Therefore you have
m = (-8 - 6) / (5 - 5) = -14 / 0
Dividing by zero will lead you to have an undefined slope
In a certain colony of bacteria each divides into two every hour. How many will be produced from a single bacillus if the rate of division continues for 4 hours
Answer:
16
Step-by-step explanation:
The number of bacteria in 4 hours = number of bacteria that divides in one hour ^ total number of hours
2^4 = 16

Tell whether the triangle with the given side lengths is a right triangle
Answer:
not a right triangle
Step-by-step explanation:
The Pythagorean Theorem states that If a triangle is a right triangle,
the hypotenuse^2 will equal to shorter^2 + longer^2
hypotenuse = 18, shorter side = 4, longer side = 17
18^2 = 4^2 + 17^2
324 = 16 + 289
324 = 305
That is false, therefore the triangle is not a right triangle

Answer: x=45
Step-by-step explanation:
Solve for c get 20 c=b so b+115 =135 180-135=x
Answer:
x=45
Step-by-step explanation:
160=115+x (use vertical angles)
subtract 115 from both sides
160-115=45
x=45
The sum of five consecutive multiples of 4 is 20.Find the smallest integer.
Answer:
The smallest integer is -4.
Step-by-step explanation:
Let the smallest integer be x.
Since the integers are all multiples of 4, they are
=> x, x+4, x+8, x+12 and x+16
=> x + x+4 + x+8 + x+12 + x+16 = 20
=> 5x + 40 = 20
Subtract 40 from both sides of the equation
5x +40 - 40 = 20 - 40
5x = -20
Divide both sides by the coefficient of x(which is 5)
[tex]\frac{5x}{5} = \frac{-20}{5}[/tex]
x = -4
∴ the smallest integer is -4.

Latoya's Fish tank has 16 L of water in it she plans to add 6 L per minute until tank has at least 46 L what is the possible number of minutes Latoya could add water?
Answer: The possible number of minutes is 5 minutes.
Step-by-step explanation: First, we should subtract: 46 - 16, since we already have 16 liters and need to get up to 46 liters. 46 - 16 gives us 30. 30 means that it is the liters needed to be filled.
Step-by-step explanation 2: Next, we know that 6 liters is filled every minute. So, basically just do 30 divided by 6, which gives us 5. 5 means the minutes.
Sooo, The possible number of minutes to fill the tank by 6 liters would be 5 minutes

A cube with a volume of 64 cubic meters is scaled by a factor of 5. What is the volume of the
modified cube in cubic meters? (Note: do not include the units in your answer.)
Clear
X Incorrect. When the sides of the cube are scaled by a factor of k = 5) the volume increases
by a factor of k = 52 = 125. Here, the new volume is 64 cubic meters 125 = 8,000 cubic
meters. Enter the correct answer

What is the equation of the line that passes through the point (-5,5) and has a
slope of -1?
Answer:
y = - x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 1 , then
y = - x + c ← is the partial equation
To find c substitute (- 5, 5 ) into the partial equation
5 = 5 + c ⇒ c = 5 - 5 = 0
y = - x ← equation of line
