Answer:
G
Step-by-step explanation:
Volume of a triangular prism = area of the base x height
(where the "bases" are the triangles)
Area of a triangle = 1/2 x base x height
Given:
base = 3.1 cmheight = 4.8 cm⇒ area of base of prism = 1/2 x 3.1 cm x 4.8 cm = 7.44 cm²
Given:
area of base = 7.44 cm²height of prism = 2.6 cm⇒ Volume of the prism = 7.44 cm² x 2.6 cm = 19.344 cm³
What is the sum (2 x 1016) + (7 1016) in scientific notation
Answer:9x1016
Step-by-step explanation:
when adding or subtracting in standard form (aka scientific notation), the powers of 10 need to be the same. If they are just add the numbers and keep the same power of 10
#2xx10^(16)+7xx10^(16)
= ( 2 + 7 ) × 10 16

Answer:
[tex]g(g(x)) = {x}^{4} + 14 {x}^{2} + 56 [/tex]
[tex]h(h(x)) = x[/tex]
Step-by-step explanation:
[tex]g(x) = {x}^{2} + 7[/tex]
[tex]g(g(x)) = {( {x}^{2} + 7)}^{2} + 7 [/tex]
[tex]g(g(x)) = {x}^{4} + 14 {x}^{2} + 49 + 7 = {x}^{4} + 14 {x}^{2} + 56 [/tex]
[tex]h(x) = \frac{5}{9x} [/tex]
[tex]h(h(x)) = h( \frac{5}{9x} )[/tex]
[tex]h(h(x)) = \frac{5}{9( \frac{5}{9x} )} = \frac{5}{ \frac{5}{x} } = 5( \frac{x}{5}) = x [/tex]

I NEED THIS RIGHT NOW
Answer:
B
Step-by-step explanation:
If the numerator is one, the denominator is going to be the same value as a normal positve interger.
Answer:
A
Step-by-step explanation:
If z = 10, y = 9, and x = 8, it would fit the fact that z > y and y > x.
If we divide 1 by the variables, then it would be 1/10, 1/9, and 1/8. Imagine this as a pie. 1/8 would be the biggest slice then because it is cut into less pieces. 1/9 would be the second biggest slice because it is cut into less pieces than 1/10. Therefore, A is the correct answer.
I hope this helps and please mark this as brainliest!

If the coordinates for C' are (4.5, 4.5), which rule best represents the dilation that was applied to rectangle ABCD to create rectangle A'B'C'D'?
The dilation of rectangle ABCD to create rectangle A'B'C'D' would change the size of the rectangle
The dilation rule is: (x,y) -> k(x,y)
How to determine the rule of dilation?The coordinates of C' is given as:
C' = (4.5, 4.5)
The coordinate of point C is not given.
So, I will apply a general rule
The general rule of dilation is:
(x,y) -> k(x,y)
Where k represents the scale factor.
Assume that k = 3, the the rule would be
(x,y) -> 3(x,y)

Answer:
collect a sample bacteria from the lake
Answer:
A- collect a sample of bacteria from the lake.
Step-by-step explanation:
It will not help to get bacteria from a RIVER since the scientist wants to learn about the LAKE. Also, getting all the lake bacteria will cause no more bacterial life to thrive, which is bad- but just a single bacteria cell isn't good either since we don't know how it reproduces and one is usually not enough.
Solving the System of Equations
Examine the system of equations.
4.2x + 8y = 41.8
–4.2x + y = 19.4
Use the linear combination method to solve the system of equations. What is the value of x?
–3
–1
1.7
6.8
Answer:
x= -3
Step-by-step explanation:
Solve the following system:
{8 y + 4.2 x = 41.8
y - 4.2 x = 19.4
In the second equation, look to solve for y:
{8 y + 4.2 x = 41.8
y - 4.2 x = 19.4
y - 4.2 x = y - (21 x)/5 and 19.4 = 97/5:
y - (21 x)/5 = 97/5
Add (21 x)/5 to both sides:
{8 y + 4.2 x = 41.8
y = 1/5 (21 x + 97)
Substitute y = 1/5 (21 x + 97) into the first equation:
{4.2 x + 8/5 (21 x + 97) = 41.8
y = 1/5 (21 x + 97)
4.2 x + (8 (21 x + 97))/5 = ((168 x)/5 + 776/5) + 4.2 x = 37.8 x + 776/5:
{(37.8 x + 776/5) = 41.8
y = 1/5 (21 x + 97)
In the first equation, look to solve for x:
{37.8 x + 776/5 = 41.8
y = 1/5 (21 x + 97)
37.8 x + 776/5 = (189 x)/5 + 776/5 and 41.8 = 209/5:
(189 x)/5 + 776/5 = 209/5
Subtract 776/5 from both sides:
{(189 x)/5 = -567/5
y = 1/5 (21 x + 97)
Multiply both sides by 5/189:
{x = -3
y = 1/5 (21 x + 97)
Substitute x = -3 into the second equation:
Answer: {x = -3, y = 34/5

A) -3

Answer:
Equation: y + 1 = -2(x - 0) OR y + 3 = -2(x - 1)
Slope: -2
Y-intercept: (0, -1)
Step-by-step explanation:
First, create an equation in point-slope form using ONE point. Using (0,-1):
y - y1 = m(x - x1)
y + 1 = m(x - 0)
Then, use both points to find slope:
[tex]\frac{y2-y1}{x2-x1} =m[/tex]
[tex]\frac{-1-(-3)}{0-1}[/tex]
[tex]\frac{2}{-1}=m=-2[/tex]
Then, plug the slope into the equation and rewrite in the form of y=mx+b:
y + 1 = (-2)(x - 0)
y + 1 = -2x
y = -2x - 1
-1 = b OR (0, -1)
Final answers:
Equation: y + 1 = -2(x - 0) OR y + 3 = -2(x - 1)
Slope: -2
Y-intercept: (0, -1)

Grayson spots an airplane on radar that is
currently approaching in a straight line,
and that will fly directly overhead. The
plane maintains a constant altitude of
7225 feet. Grayson initially measures an
angle of elevation of 19 to the plane at
point A. At some later time, he measures
an angle of elevation of 39° to the plane at
point B. Find the distance the plane
traveled from point A to point B. Round
your answer to the nearest tenth of a foot
if necessary.
Using the slope concept, it is found that the distance traveled from point A to point B was of 12060.8 ft.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
At point A, the vertical change is of 7225 feet, with an angle of 19º, hence:
[tex]\tan{19^\circ} = \frac{7225}{x_A}[/tex]
[tex]x_A = \frac{7225}{\tan{19^\circ}}[/tex]
[tex]x_A = 20982.9[/tex]
At point B, the vertical change is of 7225 feet, with an angle of 39º, hence:
[tex]\tan{39^\circ} = \frac{7225}{x_B}[/tex]
[tex]x_B = \frac{7225}{\tan{39^\circ}}[/tex]
[tex]x_B = 8922.1[/tex]
The distance in feet is given by:
[tex]d = x_A - x_B = 20982.9 - 8922.1 = 12060.8[/tex]

A garden store purchased a lawn mower and marked it up 160% from the original cost of $82.67. A week later, the store placed the lawn mower on sale for 10% off. What was the discount price?
The discount price of the lawn mower purchased by the store is $193.45.
What is the discount price?The first step is to determine the selling price of the lawn mower.
Selling price = ( 1 + 1.60) x $82.67 = 214.94
Now determine the price after the discount has been applied.
Discount price = (1 - 0.1) x 214.94 = $193.45

Which fraction below represents a terminating decimal?
A.
B.
C.
D.
Answer:
3/10
Step-by-step explanation:
The fraction, 1/12, can be written as 1/4 * 1/3. Since we know that 1/3 = 0.333333... and it doesn't terminate, we know that 1/12 doesn't terminate. Similarly 2/9 = 2/3*1/3 and 2/3 = 2*1/3, and neither of these fractions terminate. But, when dividing 3/10, you get 0.3, which terminates.
