Answer:
45.312 cubic cm
Step-by-step explanation:
Since we are not asked what to look for, we can find the volume
volume of the pyramid = 1/3 * Base area * Height
Base area = 4.8 * 4.8 = 23.04 sq. cm
HEight of prism = 5.9cm
Volume of the prism = 1/3 * 23.04 * 5.9
Volume of the prism = 135.936/3
Volume of prism = 45.312 cubic cm

Solve for x. Round to the nearest tenth, if necessary.
Answer:
x = 8.8
Step-by-step explanation:
take 20 degree as reference angle .the,
hypotenuse = OQ = x (hypotenuse is always opposite of 90 degree)
perpendicular(opposite) = PQ 3 (opposite of reference angle is perpendicular or also called as opposite)
base(adjacent) = OP (side which lies on the same line where 90 degree and reference angle)
using sin rule
sin 20 = opposite / hypotenuse
0.34 = 3 / x
x = 3/0.34
x = 8.82
x = 8.8

Answer:
[tex]c=8[/tex]
Step-by-step explanation:
When we plug in the solution [tex](x+2)[/tex], we will substitute [tex]x=-2[/tex], as [tex]-2+2=0[/tex].
To be divisible, a remainder of zero must be yielded.
Let's substitute [tex]x=-2[/tex] to see what we need to make [tex]c[/tex]:
[tex]p(-2)=4\cdot(-2)^3+c\cdot (-2)^2+(-2)+2,\\p(-2)=-32+4c[/tex]

.................................................
9514 1404 393
Answer:
see attached
Step-by-step explanation:
A graphing calculator does this very nicely.
__
The intercepts can be found by setting the other variable to zero and dividing by the coefficient of the variable of interest. This tells you the x-intercept is -2/3, and the y-intercept is -2/1 = -2. The y-intercept is conveniently on a grid point. To find other grid points on the line, it is convenient to choose integer values for x, then solve for y.
y = -3x -2
Positive values for y will require negative values of x.

- Mona Allen wants to buy a bed that costs $695. The city sales tax rate is 7%. In a nearby city the sales tax rate is 4%. How much less would the bed cost if Mona bought it in the nearby city?
Answer:
$20.85 less.
Step-by-step explanation:
City sales:
7% tax = 48.65
total bed cost = $743.65
Nearby City:
4% tax = 27.8
total bed cost = $722.8
city sale - nearby city
743.65 - 722.8
=20.85

The ratio of Luke's age to Jack's age is 3:2. If Luke is 36, how old is Jack?
Answer:
Jack is 24
Step-by-step explanation:
Luke : jack
3 2
We know like is 36
3*12 = 36, so we need to multiply by 12
Luke : jack
3*12 2*12
36 24
Answer:
24
Step-by-step explanation
Notice that Luke's real age is 12 times the number in the ratio, which is a simplified version of the original ratio, where they used division by 12 on both sides to get 3:2. Just do the opposite of division, which is multiplication, and multiply both sides of the ratio to get 36:24, which means that Jack is 24 years old!

Given the following hydrogen ion concentration, determine if the solution
is acidic, basic, or neutral.
[H*] is 2.7 x 10-9 M
Answer:
The solution is basic.
Step-by-step explanation:
Applying,
pH = -log(H⁺)................. Equation 1
From the question,
Given: (H⁺) = 2.7×10⁻⁹ M
substitute these value into equation 1
pH = -log(2.7×10⁻⁹)
pH = 8.57 M.
pH scale
For acidity = 0-6
For neutrality = 7
For basicity = 8-14
From the above calculation,
The solution is basic.

The mixed fraction number in the form of an improper fraction will be 49/6.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The mixed fraction number is given below.
⇒ 8 ¹/₆
Convert the mixed fraction number into an improper fraction. Then we have
⇒ 8 ¹/₆
⇒ 8 + 1/6
⇒ (48 + 1) / 6
⇒ 49 / 6
The mixed fraction number in the form of an improper fraction will be 49/6.

What is the equation of the line that passes through the given point and is perpendicular to the given line?
Point: (1,1)
Line: y=1/5x+4/5
Step-by-step explanation:
Hey there!
The equation of a line which passes through the point (1,1) is (y-1) = m1 (x-1)...............(i) {using one point formula}
Also, another equation which is perpendicular to the line is y = 1/5 x + 4/5..........(ii)
Comparing equation (ii) with y= mx+c, we get;
Slope (m2) = 1/5.
Now, As per the condition of perpendicular lines,
m1*m2 = -1
or, m1 * 1/2 = -1
or, m1= -2
Therefore, m1 = -2.
Keeping the value of m1 in equation (i) we get;
y-1 = -2(x-1)
y-1 = -2x+1
or, y+2x-2= 0
Therefore, the required equation is 2x+y-2= 0.
