i need help
Answer:
y=-3/2x+2
Step-by-step explanation:
You can find the equation using y=mx+b, where m is the slope and b is the y-intercept. You can see the slope of this line is -3/2, and the y-intercept is 2. If you plug that into the equation, you get y=-3/2x+2

What is the value of the expression 20 ÷ 4 + (6 x 2) − 2?
A) 15
B) 17
C) 22
D) 28
Answer:
A) 15
Step-by-step explanation:
PEMDAS
20 / 4 + (6 * 2) - 2
take out the parenthesis which is P
20 / 4 + 12 - 2
there is no E
the go the rest of the way MDAS
5 + 12 - 2
17 - 2
15
Answer:
15 (A)
Step-by-step explanation:
ok first off you have to remember PEDMAS parentheses,exponents,division.multiplication,addition.subtraction(D and M are from left to right, as well as A and S.)
so the first thing you have to do is 6*2 because it is in the parentheses
this equation turns into
20/4+12-2
now do the division
5+12-2
now you have to add because it is left to right (it doesn't really matter what you o first in this situation)
17-2
15 (A)
hope this helps! have a nice day :)
Mr. Jason wants to measure his two-year old son's height. He uses a tape measure marked every half inch. What is the possible error of measurement? A. 1 in. B. 0.5 in. C. 0.1 in. D. 0.25 in.
Answer:
d
Step-by-step explanation: bc i said
The possible error of measurement is half of the smallest unit on the tape measure, which is half an inch, option B is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The possible error of measurement refers to the smallest unit of measurement on the tape measure.
In this case, the tape measure is marked every half inch, so the smallest unit of measurement is 0.5 inches.
Therefore, the possible error of measurement is also 0.5 inches.
This means that any measurement taken using this tape measure may be off by up to 0.5 inches due to the limitations of the instrument used.
Hence, the possible error of measurement is half of the smallest unit on the tape measure, which is half an inch. Therefore, the answer is B. 0.5 in.

Which statement about 192' is correct?
Answer: yes it’s option C
Step-by-step explanation: took the test
Inequalities help us to compare two unequal expressions. The statement that is correct about 192° is option C.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
The statement that is true about 192° can be found by simplifying the given expression. Therefore, The value of the options can be simplified as shown below,
Cos(192°) > 0 ⇒ -0.978 > 0
Tan(192°) < 0 ⇒ 0.212 <0
Sin(192°) < 0 ⇒ -0.2079 < 0
As it can be observed that only the third inequality is true. Therefore, the statement that is correct about 192° is option C.

Answer:
4th option
Step-by-step explanation:
The sum of the 3 angles in a triangle must equal 180°
(1) 60 ° + 80° + 80° = 220° ≠ 180°
(2) 90° + 90° = 180° ( with only 2 angles, no third angle
(3)
obtuse angles are greater than 90° but less than 180° , so their sum would be greater than 180°
(4) 55° + 60° + 65° = 180°
option 4 is the correct condition
A shipping container is in the shape of a right rectangular prism with a length of 13
feet, a width of 15 feet, and a height of 10 feet. The container is completely filled with contents that weigh, on average, 0.39 pound per cubic foot. What is the weight of the
contents in the container, to the nearest pound?
Answer:
371 pounds
Step-by-step explanation:
First you find how much space is in the container
length is 13
width is 15
height is 10
2 * (15 * 13 + 10 * 13 + 10 * 15)= 950
The total space in the container is 950
Then multiply it by 0.39 to find the weight
950 * 0.39 = 370.5
Round to the nearest pound
.5 rounded is rounded to a whole number
371 pounds

If a number in parenthesis is directly next to a number without, then the two numbers need multiplied.
-12(5/6)(-2/15) is an example of a double multiplication. But we'll multiply -12 and 5/6 first, then multiply the product by -2/15.
-12x5/6=14 2/5
14 2/5x-2/15=-1 23/25

Monica paid sales tax of $2.40 when she bought a new bike helmet. If the sales tax rate was 6%, how much did the store charge for the bike helmet before tax?
Answer: $40
Step-by-step explanation:
The tax rate is 6% on the price of the good bought.
This means that $2.40 is 6% of the price of the helmet before taxes.
Assuming the before tax price is x, the price of the helmet is:
2.40 = x * 6%
x = 2.40 / 6%
x = $40
$40 is the before tax cost.
Find the value of x please!! ASAP
Answer:
x = 10
Step-by-step explanation:
By looking at the picture, I can tell the angle of the 3x is also 30 degrees.
This means 3x = 30.
When you solve for x by dividing each side by 3, you result with the answer of x = 10.
To check you work, plug in 10 for x to recieve 30 degrees again.

Element X decays radioactively with a half life of 6 minutes. If there are 390 grams of
Element X, how long, to the nearest tenth of a minute, would it take the element to
decay to 28 grams?
y =
= a(.5)^ t/h
Answer:
The time it would take the element to decay to 28 grams is approximately 22.5 minutes
Step-by-step explanation:
The give half life of element X = 6 minutes
The given initial mass of the radioactive element X = 390 grams
The mass of the element X after decay = 28 grams
The function that represent the decay of element X is given as follows here;
[tex]y = a \cdot (0.5)^{\dfrac{t}{h} }[/tex]
Which is of the form;
[tex]N(t) = N_0 \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{1/2}}[/tex]
Therefore;
h = 6 minutes = The time duration of the half life
a = N₀ = The initial mass = 390 g
N(t) = The final mass = 28 g
t = The time it takes the element to decay
Plugging in the values gives;
[tex]28 = 390 \times(0.5)^{\dfrac{t}{6} }[/tex]
[tex](0.5)^{\dfrac{t}{6} } = \dfrac{28}{390}[/tex]
Therefore;
[tex]\dfrac{t}{6} \times ln\left(0.5} \right) = ln \left(\dfrac{28}{390} \right)[/tex]
t/6 = ln(29/390)/ln(0.5)
t = 6 × ln(29/390)/ln(0.5) ≈ 22.496
Given the answer to the nearest tenth of a minute, the time it would take the element to decay to 28 grams, t ≈ 22.5 minutes.
