A biologist uses a rectangular tray that has a width of 1.5 feet and a height of 2 feet. What is the area of the tray in square feet?
Answer: 3ft squared
Step-by-step explanation: to find the area you have to multiply the height by the width. So 2 times 1.5 is equal to 3.

Factor this polynomial expression.
15x^2- 2x - 8
O A. (5x + 4)(3x - 2)
O B. (5x - 4)(3x+2)
O C. (5x + 2)(3x - 4)
O D. (5x-2)(3x+4)
Answer:
B. (5x - 4)(3x + 2)
Step-by-step explanation:
Factor the following:
[tex] \longrightarrow [/tex] 15x² - 2x - 8
The coefficient of x² is 15 and the constant term is -8. The product of 15 and -8 is -120. The factors of -120 which sum to -2 are 10 and -12.
So,
[tex] \longrightarrow [/tex] 15x² + (10 - 12)x - 8
[tex] \longrightarrow [/tex] 15x² + 10x - 12x - 8
[tex] \longrightarrow [/tex] 5x(3x + 2) - 4(3x + 2)
[tex] \longrightarrow [/tex] (5x - 4)(3x + 2)
Matea recorded that water levels in one part of the river fell 1.05 millimeters per year for 2.48 years. Describe how you could estimate the total variation in water level.
Answer:
the answer is -13.64 i just took the test and it right promise.
Step-by-step explanation:
mark me as brainliest pls its right
Answer:
The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6
Use the Pythagorean Theorem to find the length of the sides "d" and "f." Explain your answer.
Answer:
f = 10·√3/3 ≈ 5.774
d = 5·√3/3 ≈ 2.887
Step-by-step explanation:
The given parameters are;
The angles opposite the 90°, right angle, = 60° and 30°
The length of the leg opposite the 60° angle = 5
Therefore, by Pythagorean Theorem, we have;
f² = d² + 5²
However, by trigonometry, we have;
sin(θ) = Opposite/Hypotenuse
For the angle of the triangle, θ = 30°, we have;
sin(30°) = d/f = 0.5
∴ d = f × 0.5 = 0.5·f
Substituting the value of d in the equation given by Pythagorean Theorem, we have;
f² = (0.5·f)² + 5² = 0.25·f² + 5²
f² = 0.25·f² + 5²
f² - 0.25·f² = 5²
0.75·f² = 5²
f² = 5²/0.75 = 100/3
f = 10/√3 = 10·√3/3
f = 10·√3/3
d = f × 0.5 = 10·√3/3 × 0.5 = 5·√3/3
d = 5·√3/3.
HURRY HELP NOW!! Solve for x please !!!!
Answer:
X=9 so D
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
70 and 12x + 2 are same- side interior angles and are supplementary, thus
12x + 2 + 70 = 180 , that is
12x + 72 = 180 ( subtract 72 from both sides )
12x = 108 ( divide both sides by 12 )
x = 9 → D
jack is paid £1800 a month. he spends half his money on rent. he spends the rest on food, bills and savings in the ratio 4:3:2 how much does he spend on bills?
Answer:
£300.
Step-by-step explanation:
He has £900 left after paying rent.
The fraction he spends on bills = 3(4+3+2)
= 3/9
= 1/3.
So he spends 900 * 1/3 = £300 on bills.
Twice as many students go to the park than to the theater. Five more students go to the theater than to the museum. If 16 students go to the park, how many students go to the museum?
Answer:
3 students
Step-by-step explanation:
Twice as many students go to the park than to the theater :
Let number who go the theater = t
Number who goes to park = 2t
5 more students go to the theater than to the museum
Number who goes to museum = t - 5
If number of students who goes to park = 16
How many students goes to the museum :
2t = 16
t = 16/2
t = 8
Number who goes to museum = t - 5
t - 5 = 8 - 5 = 3
Hence, number of students who goes to the museum = 3

Prove: m = -2
please help im very confused :)
also make sure to include the statements and reasonings as shown in the screenshot!
Answer:
See Below.
Step-by-step explanation:
1) Given:
[tex]3x+2y+7=5x+3y+10[/tex]
2) Subtraction Property of Equality (subtract 2y from both sides):
[tex]3x+7=5x+y+10[/tex]
3) Subtraction Property of Equality (subtract 5x from both sides):
[tex]-2x+7=y+10[/tex]
4) Subtraction Property of Equality (subtract 10 from both sides):
[tex]-2x-3=y[/tex]
5) Symmetric Property:
[tex]y=-2x-3[/tex]
6) Slope-intercept form:
[tex]y=mx+b\text{, where $m$ is slope and $b$ is y-intercept.}[/tex]

A medium-sized (4-pound) sugar pumpkin should yield around 1½ cups of mashed pumpkin. So, if a 4-pound pumpkin will yield about 1.5 cups of mashed pumpkin (pumpkin puree), how many cups of pumpkin puree will Steve Geddes' 2,528-pound pumpkin yield?
Answer: 948
Step-by-step explanation:
From the question, we are informed that 4-pound pumpkin will yield about 1.5 cups of mashed pumpkin (pumpkin puree).
Therefore, the number of cups of pumpkin puree that Steve Geddes' 2,528-pound pumpkin will yield will be:
= (2528/4) × 1.5
= 632 × 1.5
= 948 cups of pumpkin puree
A 450 gallon tank full of water is draining at a rate of 20 gallons per minute. We can represent the situation with the equation:
y
=
450
−
20
x
y
=
450
-
20
x
where x is the number of minutes that have passed by, and y is the amount of water in the tank. How long will it take for the tank to have 200 gallons?
A.
12.5 minutes
B.
32.5 minutes
C.
2.15 minutes
D.
20 minutes
Replace y with 200 ( amount of water in the tank) and solve for x:
200 = 450 -20x
Subtract 450 from both sides:
-250 = -20x
Divide both sides by-20:
X = 12.5
The answer is A. 12.5 minutes
Evaluate each value expression for the given value of x: 11 + x, x=12
Answer:
The value of 11+x at x=12 will be 23.
Step-by-step explanation:
Given the expression
[tex]11 + x[/tex]As we have to evaluate the expression at x=12
so substitute the value x=12 in the expression
[tex]11 + x[/tex]
[tex]=11+12[/tex]
[tex]=23[/tex]
Therefore, the value of 11+x at x=12 will be 23.
