Question 3 options:
x≤2
x≥2
x≤3
x≥3
Answer:
option D
x≥3
Step-by-step explanation:
Given in the question an inequality
−4x + 2 ≤ −10
rearrange x terms to the left and constant to the right
-4x ≤ −10 - 2
-4x ≤ -12
cancel - on both sides, due to sign change inequality will also be change
4x ≥ 12
x ≥ 12/4
x ≥ 3
So, the solution of the inequality is x ≥ 3, x is greater than or equal to 3.
Answer:
x ≥ 3
Step-by-step explanation:
We have given a inequality.
−4x+2 ≤ −10
We have to find the solution of given inequality.
Adding -2 to both sides of given inequality, we have
-4x+2-2 ≤ -10-2
-4x ≤ -12
Cancelling negative sign from both sides of above inequality , we have
4x ≥ 12
Dividing by 4 to both sides of above equations, we have
x ≥ 3 which is the solution of inequality.

Step-by-step explanation:
Given in the question,
The distance probe travels at an angle of depression 67.4 from the ship to the ocean surface = 4000m
We will use trigonometry identities
sinФ = opposite / hypotenusecosФ = adjacent/ hypotenuse1)
distance of probe from top of sea to surface = x
cos(90 - 67.5) = x / 4000
x = 3695.5 m
2)
horizontal distance from ship to probe = y
sin(90-67.5) = y / 4000
y = 1530.73 m

A right rectangular prism has a length of 5 cm, a width of 4 cm, and a height of 3 cm. The dimensions of the prism are doubled. What is the surface area of the enlarged prism?
Answer:
376 square centimeters
Step-by-step explanation:
When doubled, the new length is 5*2=10 cm, new width is 4*2=8 cm, and new height is 3*2=6 cm.
The surface area of a rectangular prism is given by : [tex]2(lw+wh+lh)[/tex]
Where l is length, w is width, and h is height
Plugging in the new values we get:
[tex]2(lw+wh+lh)\\=2((10)(8)+(8)(6)+(10)(6))\\=2(80+48+60)\\=2(188)\\=376[/tex]
The surface area of the enlarged prism = 376 cm^2
Answer: 376 cm²
Step-by-step explanation:
If the dimensions are doubled then:
length=10cm
width=8cm
height=6cm
You must apply the formula for calculate the surface area of a rectangular prism, whih is shown below:
[tex]SA=2(wl+lh+hw)[/tex]
Where l is the length, w is the width and h is the height.
WHen you substitute values, you obtain the following result:
[tex]SA=2[(8cm*10cm)+(10cm)(6cm)+(6cm)(8cm)][/tex]
[tex]SA=376cm^2[/tex]
Convert 6 10/36 to an improper fraction in lowest terms
ANSWER
[tex] \frac{113}{18} [/tex]
EXPLANATION
We want to convert
[tex]6 \frac{10}{36} [/tex]
to improper fraction.
Let us first reduce the fractional part to get;
[tex]6 \frac{5}{18} [/tex]
We now multiply 6 by 18 and add 5 and then express the result over 18.
This will give us;
[tex] = \frac{6 \times 18 + 5}{18} [/tex]
[tex] = \frac{108 + 5}{18} [/tex]
[tex] = \frac{113}{18} [/tex]
To convert the mixed number 6 10/36 to an improper fraction, first simplify the fraction to 5/18. Then multiply the whole number by the denominator (6 * 18 = 108) and add the numerator (108 + 5) to get 113/18, which is in its lowest terms.
To convert the mixed number 6 10/36 to an improper fraction in its lowest terms, follow these steps:
First, simplify the fractional part of the mixed number by dividing the numerator and denominator by their greatest common divisor. In this case, 10/36 can be simplified because 2 is the greatest common divisor of 10 and 36. So, 10 \/ 2 = 5 and 36 / 2 = 18, which gives us 5/18.
Next, convert the mixed number to an improper fraction by multiplying the whole number by the denominator of the fraction then adding the numerator. 6 (the whole number) \\times 18 (the new denominator) = 108. Then add the numerator: 108 + 5 = 113.
The result is the improper fraction 113/18.
This improper fraction 113/18 is already in its lowest terms as the numerator and denominator have no common factors other than 1.

Urvi solved a fraction division problem using the rule “multiply by the reciprocal.” Her work is shown below.
Answer:
D. Urvi multiplied with the reciprocal of the dividend instead of the reciprocal of the divisor.
Step-by-step explanation:
We know that Urvi solved a fraction division problem using the rule “multiply by the reciprocal.”
According to this rule, “multiply by the reciprocal”, we need to take the reciprocal of the divisor (denominator) and multiply with the dividend in its original form.
Looking at the calculations made by Urvi, we can see that she took the reciprocal of the dividend and not the divisor.
Therefore, the correct answer option is D. Urvi multiplied with the reciprocal of the dividend instead of the reciprocal of the divisor.

Mike started saving money by putting 50 dollars aside. Each month, he adds more money than the month before. At the end of 36 months, he has saved 4950. How much more does he add each month?
Answer:
He add $5 more each month
Step-by-step explanation:
* Lets consider this problem as an arithmetic sequence because
he add every month x dollars more
∵ He start with 50 dollars ⇒ a (1st amount)
∵ He add x dollars every month ⇒ d
∵ He did that for 36 months ⇒ n
∵ He saved 4950 dollars ⇒ Sn
∵ Sn = n/2[2a + (n - 1)d]
* Where Sn is the total money after n months
a is the first amount he saved
d is the money he add more each month
∴ 4950 = 36/2[2(50) + (36 - 1)(x)]
∴ 4950 = 18[100 + 35x]
∴ 4950/18 = 100 + 35x
∴ 35x = 275 - 100 = 175
∴ x = 175/35 = 5 dollars
Answer:
Mike added $5 more each month.
Step-by-step explanation:
We are given that Mike started saving money by putting $50 aside. Each month, he adds more money than the previous month and so by the end of 36 months, he saved $4950.
Assuming this to be an arithmetic sequence:
[tex]S_n = \frac{n}{2} (2a+(n-1)d)[/tex]
where [tex]S_n=4950[/tex], [tex]n=36[/tex], [tex]a=50[/tex] and [tex]d= x[/tex].
Substituting the given values in the above formula to find how much more money does he add each month.
[tex]4950 = \frac{36}{2} (2 \times 50+(36-1)d)[/tex]
[tex]4950=1800+630x[/tex]
[tex]x=\frac{3150}{630}[/tex]
[tex]x=5[/tex]
Therefore, Mike added $5 more each month.

The area of a rectangle is 229.2 m2. If the length is 15 m, what is the perimeter of the rectangle
Answer:
[tex]\large\boxed{P=60.56\ m}[/tex]
Step-by-step explanation:
The formula of an area of a rectangle:
[tex]A=lw[/tex]
l - length
w - width
We have
[tex]A=229.2\ m^2\\\l=15\ m[/tex]
Substitute:
[tex]15w=229.2[/tex] divide both sides by 15
[tex]w=15.28\ m[/tex]
The formula of a perimeter of a rectangle:
[tex]P=2(l+w)[/tex]
Substitute:
[tex]P=2(15+15.28)=2(30.28)=60.56\ m[/tex]
Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the following equation.
Point: (−1,−2)(−1,−2)
Equation: 3x−y=53x−y=5
Parallel Equation: y=
Answer:
y = -3x -5
Step-by-step explanation:
Parallel lines are parallel because they never intersect. As such, they have the same slope. The equation 3x - y = 5 can be converted to slope intercept form to find the slope. The slope of the line y = -3x - 7 is -3. Substitute m = -3 and the point (-1,-2) into the point slope form of a line.
[tex]y -y_1 = m(x-x_1)\\y --2 = -3(x --1)\\y + 2 = -3(x+1)\\[/tex]
You can convert the equation to slope intercept form by using the distributive property.
y + 2 = -3(x+1)
y + 2 = -3x - 3
y = -3x - 5

A swimming pool is 15 feet wide, 50 feet long, and has an average depth of 5 feet. How many cubic feet of water will it hold
it can hold water equal to volume of swimming pool.
so volume of swimming pool = L × B ×H
= 50 ×15 × 5 = 3750 cubic feet
The amount of water it will hold is 3750 feet³
Step-by-step explanation:According to the problem we need to find the volume of the pool
Volume = length x width x height
Volume = 15 x 50 x 5
Volume = 3750 feet³
So the amount of water it will hold is 3750 feet³
A person operating a machine can mow 0.75 acres in ½ hour. What is the rate, in acres per hour, that the person can mow? Write your answer as a decimal.
1.50 acres is the answer.
Final answer:
The mowing rate is 1.5 acres per hour
Explanation:
To find the rate at which a person can mow in acres per hour, we need to use the data provided that a person can mow 0.75 acres in ½ hour. To convert this to a rate in acres per hour, we divide the acres mowed by the hours it took to mow them:
To find the rate at which the person can mow, we need to divide the number of acres mowed by the time taken. In this case, the person can mow 0.75 acres in 1/2 hour.
So, the rate at which the person can mow is 1.5 acres per hour
Rate (in acres per hour) = Acres mowed / Hours taken = 0.75 acres / 0.5 hours = 1.5 acres per hour
Thus, the person can mow at a rate of 1.5 acres per hour.

Answer:
115

360 water in 5 days
245 water in 5 days
360-245=115
Please mark Brainliest
Answer:
115 bottles of water
Step-by-step explanation:
To make this easier, let us find out how many items he sells in one day. We can do this by dividing his original sales by 3, since it took him 3 days to sell the original.
[tex]\frac{147}{3} = 49[/tex]
[tex]\frac{216}{3} = 72[/tex]
We now know it took Mr. Nelson one day to sell 49 bags of popcorn and 72 bottles of water.
To find out how much Mr. Nelson sold in 5 days, all we need to do is multiply the numbers by 5.
[tex]49 * 5 = 245[/tex]
[tex]72*5=360[/tex]
It takes Mr. Nelson 5 days to sell 245 bags of popcorn and 360 bottles of water. However, the question is asking how many MORE bottles of water than bags of popcorn will he sell in five days.
Since we have how many he sold in five days, we need to get the difference of the two answers by subtracting them:

find the solution of this system of equations 6x+3y=12 6x-5y=60
Answer:
(5, - 6)
Step-by-step explanation:
Given the 2 equations
6x + 3y = 12 → (1)
6x - 5y = 60 → (2)
Multiply (2) by - 1 and add to (1) will eliminate the term in x
- 6x + 5y = - 60 → (3 )
Add (1) and (3) term by term
(6x - 6x) + (3y + 5y) = (12 - 60)
8y = - 48 ( divide both sides by 8 )
y = - 6
Substitute y = - 6 into (1) or (2) and siolve for x
Using (1), then
6x - 18 = 12 ( add 18 to both sides )
6x = 30 ( divide both sides by 6 )
x = 5
Solution is (5, - 6)
The solution to the system of equations 6x + 3y = 12 and 6x - 5y = 60 is x = 2 and y = -6.
Explanation:The subject of this question is to find the solution to a system of two linear equations. These equations are: 6x + 3y = 12 and 6x - 5y = 60.
To find the solution to these, one way is to subtract one equation from the other to eliminate x. When we subtract the second equation from the first, we get: (6x+3y) - (6x-5y) = 12 - 60. This simplifies to 8y = -48.
Therefore, y = -48 ÷ 8 which gives the solution y = -6. Substituting y = -6 into the first equation gives us 6x = 12 - 3*(-6), which becomes 6x = 12 to get x = 2.
So the solution to this system of equations is x = 2 and y = -6.
