Ms. Brown is planting a rectangular garden. The garden is 90 feet long and 50 feet wide. What is the area of her garden ?
Answer:
4,500
Step-by-step explanation:
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width.

Find the area of a vertical cross section through the centers of the bases of a cylinder with a height of 24 inches and a circumference of about 43.96 inches. Use 3.14 for π.
brainliest for who gets it right
Answer:
Step-by-step explanation:
Answer:
405 in^2
Step-by-step explanation:
Given data
Height= 27in
Circumference= 47.1 in
let us find the radius and the diameter of the base of the cylinder
from
C=2πr
47.1= 2*3.142*r
47.1= 6.284r
r= 47.1/6.284
r= 7.5 in
Diameter= 2r
D= 7.5*2
D= 15in
Hence the area of the cross-section
=H*D
=27*15
=405 in^2
an orange divided into 10 equal sections lilly ate 4 four sections manny and emma ate the remaing sections what fractions of the orange did manny and emma eat
Answer:
6/10 if its talking about Manny and Emma together, 3/10 if it separate. Simplified would be 3/5 and 3/10
Step-by-step explanation:
Lilly ate 4/10 sections. 10 - 4 is 6. so there are 6 sections left for them to eat.
Olivia works at a company that creates mobile phones. She wanted to estimate the mean amount of time their new phone's battery lasts with regular use after a full charge. She took a random sample of 6 of these phones and randomly assigned each of them to a volunteer. She instructed them to fully charge the phones and use them as they regularly would until the battery died (without recharging the phone). Here are the data they reported:
Assume that all conditions for inference are met.
Which of the following is a 90% confidence interval for the mean battery life (in hours)?
Answer:
9+- 1.7
Step-by-step explanation:
Kahn
The required possible 90% confidence interval for the mean battery life is (10.95, 19.05) hours.
What is Statistic?Statistic is the study of mathematics that deals with relations between comprehensive data.
Here,
Assuming that the sample means and sample standard deviation were calculated from the data, a possible 90% confidence interval for the population means battery life can be calculated using the t-distribution.
For example, if the sample mean is 15 hours and the sample standard deviation is 3 hours, with a sample size of 6 and a 90% confidence level, the t-interval would be:
t-interval = sample mean ± t*(sample standard deviation / √(sample size))
where t is the t-value with (sample size - 1) degrees of freedom and a 90% confidence level.
Using a t-table, the t-value for 5 degrees of freedom and a 90% confidence level is approximately 2.571. Plugging in the values, we get:
t-interval = 15 ± 2.571*(3 / √(6))
t-interval ≈ (10.95, 19.05)
Therefore, a possible 90% confidence interval for the mean battery life is (10.95, 19.05) hours.

What’s the area??
BTW THE ANSWER IS NOT 78
Answer:
She shaded area?
12 x 10 = 120
6 x 7 = 42
42 divided by 2 = 21
Now we subtract both areas:
120 - 21 = 99 of the shaded region.
Answer:
99
Step-by-step explanation:
7 * 6 is 42 then divide by 2 = 21
12 * 10 is 120
120 - 21 = 99

Answer:
x=10, y=-5
Step-by-step explanation:
2x+3y=5, y= 5-x; change y to 5-x:
2x+3(5-x)=5
2x-3x+15=5
-x=5-15
-x=-10
x=10

Which equation, when graphed would appear narrower than the graph of y= 3x2 + 5
Answer:
y = 4x^2 + 5 has the narrowest graph.
Step-by-step explanation:
The larger the coefficient of x^2 is, the narrower the graph will be. Thus:
y = 4x^2 + 5 has the narrowest graph.

Si un rombo tiene un lado con medida de 16 pulgadas. Cual es su perimetro . If a rhombus has a side measured 16 inches. What is its perimeter.
Answer:
64 inches or 64 pulgadas
Step-by-step explanation:
The formula for the perimeter of a rhombus is given as:
P = 4a
Where a = side length of the rhombus
From the above question, side length of the rhombus = 16 inches
Hence, Perimeter of the rhombus = 4 × 16 inches
= 64 inches
La fórmula para el perímetro de un rombo se da como:
P = 4a
Donde a = longitud del lado del rombo
De la pregunta anterior, la longitud del lado del rombo = 16 pulgadas
Por lo tanto, perímetro del rombo = 4 × 16 pulgadas
= 64 pulgadas

Please explain your answer, I will give brainliest, thank you!
Answer:
[tex] \displaystyle \text C)\csc( {225}^{ \circ } )= - \sqrt{2} [/tex]
Step-by-step explanation:
we want to figure out the exact value of the following:
[tex] \displaystyle \csc( {225}^{ \circ} ) [/tex]
recall that,
[tex] \displaystyle \csc( \theta ) = \frac{1}{ \sin( \theta)} [/tex]
we are given [tex]\theta=225°[/tex]
substitute:
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{1}{ \sin( {225}^{ \circ} )} [/tex]
225° belongs to Q:III which we can clearly acquire from unit circle so,
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{1}{ \dfrac{ - \sqrt{2} }{2} } [/tex]
By simplifying complex fraction we get:
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2}{ - \sqrt{ 2} } [/tex]
notice that, what we acquired isn't in the option so multiply it by √2/√2
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2}{ - \sqrt{ 2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } [/tex]
simplify multiplication:
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2 \sqrt{2} }{ - \sqrt{ 4} } [/tex]
simplify square:
[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2 \sqrt{2} }{ - 2} [/tex]
reduce fraction:
[tex] \displaystyle \csc( {225}^{ \circ } )= - \sqrt{2} [/tex]
hence,
our answer is C
Amanda has $227 worth of bills in her purse. She has six more $5 bills than $10 bills. The number of $1 bills is three fewer than 25 times the number of $10 bills. How many bills of each kind does Amanda have?
Answer:
There are six $5 bills and nine $10 bills
Step-by-step explanation:
x= $5 bills
y= $10 bills
x+y=15
5x+10y=120
5x+10(15-x)=120
5x+150-10x=120
-5x= -30
x=6 so y=9
Answer:
$10 = 5 $5 = 11 $1 = 122
Step-by-step explanation:
5 x 10 = 50
5 x 11 = 55
1 x 122 = 122
50 + 55 + 122 =

Find the volume of a right circular cone that has a height of 9.7 ft and a base with a radius of 7.6 ft. Round your answer to the nearest tenth of a cubic foot.
Answer:
586.7 ft^3
Step-by-step explanation:
1) find the base area
base area = radius^2 x pi = 7.6^2 x pi = 181,458392 ft^2
2) find the volume
V = (base area x height)/3 = (181,458392 x 9.7)/3 = 586.7 ft^3
