The width of a rectangular room is 80%
of
its length. The length of the room is 15 feet.
What is the width of the room?
Answer:
12 feet
Step-by-step explanation:
Given: length = 15 feet, width = L x 80%
Unknown: width = ?
width = L x 80%
w = (15ft) x 80% or (15ft) x .80
w = 12 ft
Answer:
Formula of rectangle :-
l ×b
80/100 × 15 ×b
8/10 × 15 ×b
80/100 × 15 =b
8/10 ×15 =b
4/5 × 15 =b
4 × 3 = b
b = 12feet
b = 12 feet
Rewrite the expression
as square of a monomial.
81x^6y^4
Answer:
[tex](9x^3y^2)^2[/tex]
Step-by-step explanation:
The expression, as a square of a monomial, will be given by:
[tex](\sqrt{81x^6y^4})^2[/tex]
Now, we calculate the root, applying it's properties. So
[tex]\sqrt{81x^6y^4} = \sqrt{81} \times \sqrt{x^6} \times \sqrt{y^4} = 9 \times x^{\frac{6}{2}} \times y^{\frac{4}{2}} = 9x^3y^2[/tex]
The expression as a square of a monomial is given by
[tex](9x^3y^2)^2[/tex]

Help! I got 3 but it says its wrong. Anyone else have any answers that they solved for w/ proof?
Answer:
Your answer is indeed correct. f(-8) = 3
Step-by-step explanation:
[tex]f(x) = -x^{2} - 4x + 35\\f(-8) = -( -8)^{2} - 4(-8) + 35\\f(-8) = -64 + 32+ 35\\f(-8) = 3[/tex]

Find the area of the triangle im not sue how to do this best answer gets brainly
Given :
▪︎Length of height of this triangle = 16 cm
▪︎Length of base of this triangle = 4 cm
We know that :
[tex]\color{hotpink}\tt \: area \: of \: a \: triangle \color{plum}= \frac{1}{2} \times base \times height[/tex]
Which means :
The area of this triangle :
[tex] = \tt \frac{1}{2} \times 16 \times 4[/tex]
[tex] =\tt \frac{1}{2} \times 64[/tex]
[tex] = \tt \frac{64}{2} [/tex]
[tex]\color{plum} =\tt\bold{ 32 \: {cm}^{2} }[/tex]
▪︎Therefore, the area of this triangle = 32 sq.cm

A student measured the numbers of stomata per mm of leaf
surface. Their counts were: 250, 280, 265, 245, 270, 255, 290.
Calculate the mean number of stomata (to 3 significant
figures).
Answer:
When we have a set of N numbers like:
{x₁, x₂, ..., xₙ}
The mean of the set is:
M = (x₁ + x₂ + ... + xₙ)/N
In this case, we have the set:
{250, 280, 265, 245, 270, 255, 290}
So we have a set of 7 elements.
The mean of this set will be:
M = (250 + 280 + 265 + 245 + 270 + 255 + 290)/7 = 1855/7 = 265
So the mean number of stomata per mm of leaf surface is 265.
52° 38° 128 xo degrees
Answer:
x = 142°
Step-by-step explanation:
Since angle x and the 38° angle are supplementary angles, we know that the following is true...
x + 38° = 180°
x = 180° - 38°
x = 142°
Factor the expression:
9x(x^2 - 1) - 3(x^2 - 1)

explain how you can use fractions strips or number lines to show that 3/4 and 6/8 are equivalent.
Answer:
answers is down there
Step-by-step explanation:
you can use fraction strips by using them 3/4 and 6/8 because they are equivalent and that's just life :)
3/4 and 6/8 are equivalent numbers/fractions
The fractions are given as:
[tex]\frac 34[/tex] and [tex]\frac 68[/tex]
To model 3/4 using number lines, we do the following steps
Draw a straight lineDivide into 4 equal segmentsPut a mark at the end of the 3rd pointTo model 6/8 using number lines, we do the following steps
Draw a straight lineDivide into 6 equal segmentsPut a mark at the end of the 6th pointWhen both points are compared, then we find out that:
[tex]\frac 34 \equiv \frac 68[/tex]
Hence, 3/4 and 6/8 are equivalent

Okay so first of all, we want to find the probability of picking that first purple marble. There are 8 purple marbles you can chose out of a possible 12 marbles, so the probability is 8/12, or 2/3.
Next, find the probability of finding the second purple marble. Since you took out one purple marble already, there are 7 purple marbles you could chose out of a possible 11 marbles, so the probability is 7/11.
To find out the probability of both of these events happening, you multiply these probabilities:
[tex]\frac{2}{3} * \frac{7}{11}\\\frac{2*7}{3*11} \\\frac{14}{33}[/tex]
