Volume of cuboid =l×b×h
area of base of the cuboid =l×b
hence
volume of cuboid is = area of base × height
140=88×h
h=140÷88
h=5
ABCD is a parallelogram, find the value of y
Answer:
33
Step-by-step explanation:
angles A and B should add up to 180, so A must be 40, and because it is a parallelogram the anlge across from it should also equal 40. 33+7=40.

Hey there! I know this is prob really simple and I am beginning to understand it, but my problem is
Sec 60°
Now I know all the SOH CAO TOH stuff, and things like that, I just don't understand how to find the value because it changes all the time with the right triangle and the number of their sides.
Really just need the formula on how to solve stuff.
Answer:
sec(60) = 2
Step-by-step explanation:
sec(theta) = 1/cos(theta)
theta = 60o
cos(60) = 1/2 = 0.5
sec(theta) = 1/0.5 = 2

A circle of radius 90 inches has a central angle that intercepts an arc of length 120 inches. Explain whether the measure of the central angle is 34 radians
A. The measure is not 34 radians. The measure is 32 radians because the angle measure in radians is the diameter divided by the arc length.
B. The measure is not 34 radians. The measure is 43 radians because the angle measure in radians is the arc length divided by the radius.
C. The measure of the angle is 34 radians because the angle measure in radians is the radius divided by the arc length.
D. The measure is not 34 radians. The measure is 23 radians because the angle measure in radians is the arc length divided by the diameter.
Answer:
D

Find the product. Your answer must be in simplest form.
7/8 of 56
Answer:
You probably know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.
Here's a little tip for you. Any number can be converted to fraction if you use 1 as the denominator:
56
1
So now that we've converted 56 into a fraction, to work out the answer, we put the fraction 7/8 side by side with our new fraction, 56/1 so that we can multiply those two fractions.
That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:
7 x 56
8 x 1
=
392
8
In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.
You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 392 and 8 is 8.
We can now divide both the new numerator and the denominator by 8 to simplify this fraction down to its lowest terms.
392/8 = 49
8/8 = 1
When we put that together, we can see that our complete answer is:
49
1
The complete and simplified answer to the question what is 7/8 of 56 is:
49
Hopefully this tutorial has helped you to understand how to find the fraction of any whole number. You can now go give it a go with more numbers to practice your newfound fraction skills.
Step-by-step explanation:
Answer:
forty nine
Step-by-step explanation:
convert 56 into a fraction (56/1) then multiply 7/8 × 56/1. it equals out to 392/8. then find the GCF of 392 and 8, which is 8. now divide boht the new numerator and denominator by 9 to simplify it to lowest terms. 49 is the answer

Step 2: Identify

[tex]\int\limits {\frac{1}{\sqrt[]{x} }*\frac{1}{\sqrt[]{ 1-x^{2}}} } \, dx[/tex]
U-substitution:
let u = [tex]x^{1/2}[/tex] [So, x = u²]
[tex]\frac{du}{dx} = \frac{1}{2\sqrt[]{x}}[/tex] [differentiating both sides wrt x]
dx = du*2√(x)
dx = 2u(du) [Since u = √x]
Finding the Integral:
Plugging these values in the given expression:
[tex]\int\limits {u^{-1}*(1-u^{2})^{-1/2} } \, 2\sqrt[]{x}*du[/tex]
[tex]\int\limits {\frac{1}{u}*\frac{1}{\sqrt[]{ 1-u^{2}}}*2u } \, du[/tex]
The 'u' in the numerator and denominator will cancel out
[tex]\int\limits {\frac{1}{\sqrt[]{ 1-u^{2}}}*2 } \, du[/tex]
Since 2 is a constant
[tex]2\int\limits {\frac{1}{\sqrt[]{ 1-u^{2}}} } \, du[/tex]
Using the property: [tex]\int\limits {\frac{1}{\sqrt[]{1-x^{2}} }} \, dx[/tex] = ArcSin(x) + C
2*ArcSin(u) + C
Since u = √x :
2*ArcSin(√x) + C

Bill sees two boxes of baseball cards at a card show. The first box has 150 cards for $12.55.The second box has 120 cards for $9.60. The cards in which box are cheaper?
Answer: Cards in second box are cheaper.
Step-by-step explanation:
We are told that the first box has 150 cards for $12.55. Therefore, the cost of one card would be:
= $12.55 / 150
= $0.084.
The second box has 120 cards for $9.60. Therefore, the cost if one card would be:
= $9.60 / 120
= $0.08
Therefore, the cards in the second box are cheaper.

Find the area of the shape below.
11 cm
14 cm
9 cm
20 cm
Answer: A = 235 cm²
Step-by-step explanation: The figure has not a regular shape, but we can divide it to other figures that are easier to calculate the area.
For example, we can divide this figure in 2:
1) A square of side 9;
2) A rectangle of sides 14 and 11;
The image below represents what it is described.
Area of quadrilateral is calculated as A = length x width
Since both rectangle and square are quadrilateral, area of each will be
[tex]A_{square}[/tex] = 9.9
[tex]A_{square}[/tex] = 81
[tex]A_{rectangle}[/tex] = 11.14
[tex]A_{rectangle}[/tex] = 154
The area of the shape is the sum of each part we calculated:
[tex]A_{total}[/tex] = 154 + 81
[tex]A_{total}[/tex] = 235
The area of the shape is 235 cm².

Select from the drop-down menus to correctly complete each statement An arithmetic sequence represents a _____ function because it has a constant rate of change. As the sequence progresses, each value an in the sequence increases or decreases by a specific amount For example, the arithmetic sequence 9, 13, 17, 21, represents a ______ function because as n increases by 1, each value an increases by _____ Therefore, this arithmetic sequence ______a function
1st line :linear or nonlinear
2nd line:linear or nonlinear
3rd line: 1 , 4 or different amounts
4th line:represents or does not represent
Answer:
1st line: linear
2nd line: linear
3rd line: 4
4th line: represents
Step-by-step explanation:
Arithmetic sequences increase by the same number each time. This means they are linear, as linear functions also increase by the same number each time.
So, the first and second lines have the answer of linear.
In the arithmetic sequence given, 4 is added to the previous number as it progresses. This represents a function.
So, the third line has the answer of 4, and the fourth line has the answer or represents.
Using arithmetic sequence concepts, it is found that the lines are:
1st: linear.2nd: linear.3rd: 4.4th: representsWhat is an arithmetic sequence?In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of the sequence is given by:
[tex]a_{n+1} = a_1 + (n-1)d[/tex]
Hence, an arithmetic sequence is also a linear function with rate of change d.
In this problem:
The sequence is: 9, 13, 17, 21.The rate of change is of 4, as when n increases by 1, each value increases by 4.Hence, the lines are completed by:
1st: linear.2nd: linear.3rd: 4.4th: representsYou can learn more about arithmetic sequence concepts at https://brainly.com/question/25433204
