The area of a trapezoid is 15 cm2. The height is 3 cm, and the bases have lengths of 2x and 3x cm. Find x, and give the lengths of the two bases.
Answer:
x = 2, bases are 4 cm and 6 cmStep-by-step explanation:
Area formula:
A = 1/2(b1 + b2)hSubstitute the given values:
15 = 1/2(2x + 3x)(3)1/2(15x) = 15x = 2The bases are:
b1 = 2*2 = 4 cmb2 = 3*2 = 6 cmA solution containing 94.4 mL of carbon tetrachloride, CCl4, dissolved in 250.0 mL of nitrobenzene, C6H5NO2, was placed in the freezer, which dropped the temperature to 0°C. Did the solution freeze at that temperature? If so, at what temperature? The density of CCl4 is 1.59g/cm3. The density of C6H5NO2 is 1.2 g/cm3.
Answer:
No, it would freeze at -16.61°C.

What is least amount of surface area possible on a rectangular prism with a volume of 64 cubic inches? What are the dimensions of this rectangular prism? LOTS OF POINTS
Answer: 96in²
Step-by-step explanation:
A cube is the most efficient rectangular prism in terms of surface area.
A rectangular prism where l = 4in w = 4in h = 4in has a volume of 64in³
This rectangular prism has a surface area of 96in²
Answer:
96
Step-by-step explanation:
3)
Solve the inequality for x.
- 4x + 16 > -64
A)
X> 12
B)
X > 20
x < 12
D
x < 20
Answer:
D: x < 20
Step-by-step explanation:
-4x + 16 > -64
subtract 16 from both sides because you must isolate x.
-4x + 16 - 16 > -64 - 16
-4x > -80
Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...
-4x/ -4 < -80/ -4
x < 20
(negative divided by a negative will result in a POSITIVE.)
Hope this helped... I truly apologize if this is wrong..
2/3(x+6)=-8 whats the value of x?
Answer:
x=-18
Step-by-step explanation:
Answer:
The answer is -18
Step-by-step explanation:
STEP 1:
[tex]3 \times \frac{2}{3} (x + 6) = 3( - 8)[/tex]
2(x+6) = -24
______________________________________
STEP 2:
Divide both sides by 2:
[tex] \frac{2(x + 6)}{2} = \frac{ - 24}{2} [/tex]
________________________________
STEP 3:
Simplify:
[tex]x + 6 = - 12[/tex]
Subtract 6 from both sides:
[tex]x + 6 - 6 = - 12 - 6[/tex]
________________________________
STEP 4:
[tex]x = - 18[/tex]
Therefore, your answer is -18.

The dance committee of Pine Bluff Middle School earns $ 72 $72dollar sign, 72 from a bake sale and will earn $ 4 $4dollar sign, 4 for each ticket they sell to the Spring Fling dance. The dance will cost $ 400 $400dollar
Answer: See explanation
Step-by-step explanation:
Since the number of tickets is represented by t and we're told that the committee earns $4 per ticket and also earned $72 from bake sale, then the inequality will be given as:
= 72+4t>400
The solution if the inequality will then be:
72 + 4t > 400
4t > 400 - 72
4t > 328
t > 328/4
t > 82
Answer:
72+4t>400
t > 82

Solve using the order of operations. (9+9+72)-4+9
PLZ ANSWER PLZ HURRY
Answer:
95
Step-by-step explanation:
The order of operations is PEMDAS
Equations in PARENTHESES come first
Numbers with EXPONENTS come second
MULTIPLICATION/DIVISION problems come next (depending on which comes first in the equation
ADDITION/SUBTRACTION comes last (again, depending on which comes first in the equation)
So we do (9+9+72) first
So that equals 90
And then we subtract 4 from 90
90 - 4 = 86
Then we add 9 to 86
86 + 9 = 95
Answer: 72 is the answer

Find the square root of 25x^2-40xy+16y^2
The square root of [tex]25x^2-40xy+16y^2[/tex] is 5x - 4y.
Given that,
The quadratic equation is [tex]25x^2-40xy+16y^2[/tex].We need to find out the square root.Based on the above information, the calculation is as follows:
[tex]= 25x^2-40xy+16y^2\\\\= (5x)^2 - (2\times 5x \times 4y) + (4y)^2\\\\= (5x - 4y)^2\\\\= \sqrt{ (5x - 4y)^2}[/tex]
= 5x - 4y
Therefore we can conclude that the square root of [tex]25x^2-40xy+16y^2[/tex] is 5x - 4y.

7 blue socks and 6, 5, 8 of non-blue socks. If you add the numbers of non-blue socks you get 19. Blue socks to non-blue would be 7:19
Answer:
The ratio is 7 to 19 or 7:19
Step-by-step explanation:
Since there are 7 blue socks and other colors are not blue we add the number of other colors. So basically 8+5+6= 19 and then 7 blue socks :)

The probability that Sara wins a raffle is given by the expression n n + 3 . Write down an expression, in the form of a combined single fraction, for the probability that Sara does not win.
Answer:
n/3
Step-by-step explanation:
n×by n is=n square.
n/3
Probability that Sara does not wins a raffle is [tex]\frac{3}{n+3}[/tex].
What is probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
Given
Probability that Sara wins a raffle is given by the expression
P(win) = [tex]\frac{n}{n+3}[/tex]
Probability that Sara does not wins a raffle is given by
P(does not win) = 1 - [tex]\frac{n}{n+3}[/tex]
= [tex]\frac{n+3}{n+3} -\frac{n}{n+3}[/tex]
= [tex]\frac{n+3-n}{n+3}[/tex]
= [tex]\frac{3}{n+3}[/tex]
Thus, probability that Sara does not wins a raffle is [tex]\frac{3}{n+3}[/tex].
