What is the answer for this math problem?
Answer:
9 feet
Step-by-step explanation:
v = lwh (volume equals length times width times height)
75.6 = 4 x 2.1 x d
multiply l and w, which is 4 x 2.1
75.6 = 8.4 x d
divide 75.6 by 8.4
9 = d
Answer:
The value of j is 9feet
Step-by-step explanation:
[tex] \hookrightarrow \sf \: v = whl[/tex]
⇒[tex] \sf {75.6 = (2.1)(4)(j) }[/tex]
⇒[tex] \sf {75.6=(2.1)(4)j}[/tex]
Step 1: Simplify both sides of the equation.
⇒[tex] \sf {75.6=8.4j}[/tex]
Step 2: Flip the equation.
⇒[tex] \sf {8.4j=75.6}[/tex]
Step 3: Divide both sides by 8.4.
⇒[tex] \sf { \frac{8.4j}{8.4} = \frac{75.6}{8.4}}[/tex]
⇒[tex] \sf {j=9}[/tex]

Step-by-step explanation:
IN EXAMPLE 6
Opposite angles are equal so you equate the first one like this
3x + 20 = 10x - 15
15 + 20 = 7x
35/7 = x
x = 5
In next question b
It is a straight line thus it's 180°
so 4n + 22 +8n -10 = 180
12n + 12 = 180
12n = 180 - 12
n =168÷ 12
n = 14

Please can u look at the following
Answer:
a) x = -10
b) x = 7
Step-by-step explanation:
a)
2(x+3) = x - 4
==> distribute the 2
2x + 6 = x - 4
==> add 4 to both sides
2x + 10 = x
==> subtract 2x from both sides
10 = -x
==> divide both sides by -1
x = -10
b)
4(5x - 2) = 2(9x + 3)
==> distribute the 4 and 2
20x - 8 = 18x + 6
==> add 8 to both sides
20x = 18x + 14
==> subtract 18x from both sides
2x = 14
==> divide both sides by 2
x = 7
Marla is making a tree skirt out of fabric. She is using a pattern based on the circle below. Marla will need to remove a sector of the circular fabric. The sector has a central angle of 60° and the radius of the circle is 3 feet.
Answer:
The area of sector is 4.71mi^2
Step-by-step explanation:
The area of the sector that Marla needs to remove is (3/2)π square feet.
How to find the surface area of some object?
Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object. Area is measured in terms of standard areas. Therefore, they are relative to each other.
We normally use a square of unit length as its size. That unit can be 1 cm, 1 meter, etc.
Now when we want to find surface area of some object, then the value we get tells us that you can fit this many unit sided squares on that object's surface.
We are given that;
Central angle = 60°
The radius of the circle = 3 feet.
Now,
To find the area of the sector that Marla needs to remove, we can use the formula:
A = (θ/360)πr^2
where A is the area of the sector, θ is the central angle of the sector, r is the radius of the circle, and π is pi (approximately 3.14).
Plugging in the values we know, we get:
A = (60/360)π(3)^2 A
= (1/6)π(9) A
= (3/2)π
Therefore, the area of the fabric will be (3/2)π square feet.

10
-week period?
Based on the mean from the sample, I would expect that the number of guests that will stay at the small hotel than at the bed and breakfast would be 4.50.
How many more guests will stay at the small hotel than at the bed and breakfast?
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
The number of guests at the small hotel in excess of those at the bed and breakfast = 7.75 - 3.25 = 4.50
To learn more about mean, please check: https://brainly.com/question/25842202
Answer:
315 more guests will stay at the small hotel than at the bed and breakfast in a 10-week period.
----------------------------------------------------------------------------------------------------------
At the small hotel, a mean of 7.75 guest stay per night. 10 weeks have 70 days, then the total amount is:
S = 7.75 x 70 = 542.5
At the bed and breakfast, the mean was of 3.25 guests per night, hence:
B = 3.25 x 70 = 227.5.
The difference is given by:
S - B = 542.5 - 227.5 = 315.
Therefore, 315 more guests will stay at the small hotel than at the bed and breakfast in a 10-week period.

Which statement is true about the discontinuities of the function f(x)?
f(x)=x+1/6x^2-7x-3
There are asymptotes at x=3/2 and x=-1/3
There are holes at x = 3/2 and x = -1/3
There are asymptotes at x = -3/2 and x = 1/3
There are holes at x = -3/2 and x = 1/3
Answer:
(a) There are asymptotes at x=3/2 and x=-1/3
Step-by-step explanation:
The denominator zeros can be found by factoring:
f(x) = (x +1)/((2x -3)(3x +1))
Neither of the denominator factors is cancelled by the numerator factor, so each represents a vertical asyptote, not a function hole.
The asymptotes are at the values of x where the denominator is zero:
2x -3 = 0 ⇒ x = 3/2
3x +1 = 0 ⇒ x = -1/3
Answer:A There are asymptotes at x=3/2 and x=-1/3

so 32 / 2 = 16 = radius

Adriana uses models to compare two decimal numbers. She says 0.53 is greater than 0.7 because 53 > 7.
A square partitioned into one hundred equal parts with fifty three parts shaded. To the right is a square partitioned into ten equal parts with seven parts shaded.
Which of these explains Adriana's mistake? (3 points)
a
Adriana incorrectly compared hundredths to tenths. She should compare 53 hundredths to 70 hundredths.
b
Adriana incorrectly compared tenths. She should compare 5 hundredths to 3 hundredths.
c
Adriana incorrectly shaded the models. She should shade seven more hundredths.
d
Adriana incorrectly counted the number of shaded parts in the models. She should compare 6 shaded parts to 7 shaded parts.
Answer:
A is your answer.
Step-by-step explanation:
.7 is the same as .70 and .70 is to the left of .53, indicateing that she incorrectly compared the hundreths to the tenths.

What two attributes have been used to sort these shapes?
Two groups of shapes, group A and B. Group A has three shapes. The first shape is a quadrilateral with two right angles and one pair of parallel lines, the second shape is a square, and the third shape is a rectangle. Group B has three shapes. The first shape is a quadrilateral that has two pairs of sides equal in length and no right angles, the second shape is a parallelogram with no right angles, and the third shape is a quadrilateral with two pairs of sides equal in length but no right angles and no parallel lines.
Shapes with perpendicular sides and shapes without perpendicular sides
Shapes with parallel sides and shapes without parallel sides
Shapes with equal sides and shapes with unequal sides
Shapes with equal angles and shapes with unequal angles
what is correct
Answer:
(a) Shapes with perpendicular sides and shapes without perpendicular sides
Step-by-step explanation:
This appears to be a reading comprehension problem, along with a requirement that you recognize squares and rectangles have right angles and pairs of parallel equal-length sides.
__
The group descriptions are very careful to say that the members of Group B have no right angles. Members of both groups have equal-length sides and parallel lines, so those are not distinguishing criteria.
The relevant attribute for sorting appears to be right angles/no right angles.

Use the relationship between the angles in the figure to answer the question.
Which equation can be used to find the value of x?
We know that,
two angles which are formed by the intersection of two lines ,are equal and are called vertically opposite angles.
ATQ,
angle x lies on a line same as the other given angle which is intersected by an another line ,
hence,
x = 52°
