Hi
Find the volume thank for answer
Given :
A cuboid shaped tank with sides 3.2 cm , 2.8 cm and 1.6 cm.
To Find :
The volume of the tank.
Solution :
We know, volume of a cuboid is given by product of its sides or :
[tex]V = l\times b \times h\\\\V = 3.2 \times 2.8 \times 1.6 \ cm^3\\\\V = 14.336 \ cm^3[/tex]
Therefore, the volume of the tank is 14.336 cm³ .
How do I solve this?

HELPPP 5TH GRADE MATHH
Answer:
When you multiply a number by a fraction, the number always decreases. When you multiply a number by 1/2, it's always half of the original number
Step-by-step explanation:
For example, take 4 x 1/2. It can be written as four halves. What do we get when we add four halves together?
1/2 + 1/2 + 1/2 + 1/2 = 2!
2 is less than 4. It is also half of the number four

11. Find the H.C.F of 96 and 120.
Answer:
24.
Step-by-step explanation:
The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
The factors of 120 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
Then the greatest common factor is 24.
which equation best represent the line of fit that is drawn??
A)
y=0.8x+15
B)
y=1.0x+10
C)
y=1.6x+8
D)
y=–0.8x +12
Answer: Choice B
y=1.0x+10
==============================================================
Explanation:
Without the actual (x,y) coordinates for each point, it's nearly impossible to get the answer. However, we can note that the blue regression line is intersecting the y axis at y = 10 (or around there). So its very likely that the answer is y=1.0x+10 which is choice B
The equation y=1.0x+10 is in the form y = mx+b with,
m = 1.0 = slopeb = 10 = y interceptThe next best answer is y = -0.8x+12, since 12 is fairly close to 10. The y intercept portion isn't fully shown but again it appears the blue line is crossing at y = 10.

Hunter did not want to spend more than 150$ for a flight from Reno to Los Angeles. Write the inequality that models this situation and determine the first two possible solutions
Answer:
[tex](a)\ x < 150[/tex]
[tex](b)\ x = 149; x = 148[/tex]
Step-by-step explanation:
Given
[tex]Amount = 150[/tex] --- not more than
[tex]x \to[/tex] spending
Solving (a): Represent as an inequality
Not more than means <
So, the inequality is:
[tex]Spending < Amount[/tex]
[tex]x < 150[/tex]
Solving (b): The first two possible solutions
These are the numbers closest to 150 i.e. 149 and 148
Hence, [tex]x = 149; x = 148[/tex]

15 > 2x – 9 > -23
The answer is 12>x>-7
Step-by-step explanation:
it's first divided into 2 parts
1 . 15 > 2x - 9
2. 2x - 9 > -23
Then solve them individually.
let's do it,
First half
15 > 2x - 9
15+9 > 2x
24 > 2x
24/2 > x
12>x
Second half
2x-9>-23
2x>-23+9
2x>-14
x>-14/2
x>-7
Joining of the two halves
We have :
12>x>-7

Answer:
24km²
Step-by-step explanation:
12-4 is 8 and if you visualize the triangle being put on top of the other triangle it makes a complete rectangle in which you multiple 8 time 3 to get 24 km²
Answer:
24 km²
Step-by-step explanation:
12 - 4 = 8
8 ÷ 2 = 4
4 · 3 = 12
12 ÷ 2 = 6
4 · 3 = 12
6 km² + 12 km² + 6 km²
24 km²

Answer:
15 = t
Step-by-step explanation:
3 = t - 12
3 + 12 = t
15 = t
Answer:
C:15 if were going off t
Step-by-step explanation:
if you switch around the equation a bit you get t-12=3 now what number minus 12 equals three thats what your trying to find so the only logical answer is C because 15-12=3 so t=15
Angle 1 and Angle 2 are supplementary. Which equation could you use to find the measure of Angle 2?
Angle 1: 67°
Angle 2: x degrees
Answer: 67 + x = 180
Step-by-step explanation:
Since the angles are supplementary, together they'd add up to 180. Since we do not know the degrees of Angle 2, we arrange x in the equation.

A line is perpendicular to x + 3y - 4 = 0 and has the same y-intercept as 2x + 5y - 20 = 0. Find the equation for the line.
This is equivalent to y = 3x+4 (slope intercept form)
By "standard form", I mean the form Ax+By+C = 0.
====================================================
Explanation:
Let's solve the first equation for y
x+3y-4 = 0
x+3y = 4
3y = 4-x
3y = -x+4
y = (-x+4)/3
y = (-x/3) + (4/3)
y = (-1/3)x + (4/3)
The equation is now in y = mx+b form, aka slope intercept form, with m = -1/3 as the slope and b = 4/3 as the y intercept. We'll focus on the slope.
Apply the negative reciprocal to this so that we go from -1/3 to +3/1 or simply 3. Flip the fraction and the sign. Note how -1/3 and 3 multiply to -1. Perpendicular slopes always multiply to -1, assuming neither line is vertical.
So this mystery perpendicular line we're after has a slope of 3.
It has the same y intercept as 2x+5y-20 = 0. Plug in x = 0 and solve for to determine the y intercept.
2x+5y-20 = 0
2(0)+5y-20 = 0
5y-20 = 0
5y = 20
y = 50/5
y = 4
The y intercept of 2x+5y-20 = 0 is y = 4, so it's also the y intercept of our final answer. Let b = 4.
-------------------------------------
We found that:
m = 3 is the slope of the perpendicular lineb = 4 is the y intercept of the perpendicular lineSo we know that,
y = mx+b
y = 3x+4
is the slope intercept form of the answer. Since your teacher gave you the equations in standard form (one version of it anyway), let's convert y = 3x+4 to that form as well
y = 3x+4
y-3x = 4
-3x+y = 4 .... one way to express standard form
-3x+y-4 = 0 .... another standard form
Some math textbooks use Ax+By = C as standard form, while others use Ax+By+C = 0. Unfortunately, it's a bit confusing because the same phrasing is used.

Show your work. a2 + b2 = c2
c is the side length of the hypotenuse. c2 is the hypotenuse side length multiplied by itself. You need to find the square root of the c2 value in order to solve for c.
We'll be using the Pythagoras property to solve this question.
According to the Pythagoras property,
H² = B² + P²H denotes hypotenuse
B denotes base
P denotes perpendicular
Here,
H = xP = 35 cmB = 12 cm→ (x)² = (35 cm)² + (12 cm)²
→ x² = 1225 cm² + 144 cm²
→ x² = 1369 cm²
→ x = √(1369 cm²)
→ x = 37 cm
Therefore, value of x is 37 cm.
