A rectangle has an area of 24 square units and a side length of 2 3/4 units. Find the other side length of the rectangle. Show your reasonings.
Answer:
8.73 units
Step-by-step explanation:
Use the area formula, A = lw
Plug in the are and given side length, and solve for w
A = lw
24 = 2.75w
Divide each side by 2.75
8.73 = w
The other side length of the rectangle is approximately 8.73 units

A and b. Find the length of arc ZY. Round to the nearest hundredth.
Answer:
5.24 inches
Step-by-step explanation:
We are to find the arc length of the above circle
The formula is given as:
2πr × θ/360
θ = 75°
Radius = 4 inches
Arc length ZY = 2 × π × 4 × (75/360)
= 5.235987756 inches
Approximately = 5.24 inches
Arc length ZY = 5.24 inches
Cindy Lou deposited $85 in the bank earning 4.5% interest annually. About how many years will it take her to earn $11.48 in interest?
Answer:
3.00 years
Step-by-step explanation:
Cindy Lou deposited $85 in the bank earning 4.5% interest annually. About how many years will it take her to earn $11.48 in interest?
Your answer
Given data
Principal= $85
Rate= 4.5%
Intterest= $11.48
The simple interest formula is
SI= PRT/100
11.48= 85*4.5*T/100
cross multiply
11.48*100= 85*4.5*T
1148=382.5T
divide both sides by 382.5
T= 1148/382.5
T= 3.00 years
Hence the time is 3 years

Answer:
A = 53°
AB = 23.3
BC = 18.6
Step-by-step explanation:
2. Given,
C = 90°
B = 37°
AC = 14
Required:
A, AB, and BC
Solution:
✔️A = 180 - (90 + 37) (sum of triangle)
A = 53°
✔️Find AB and BC using trigonometric function:
Reference angle = 37°
Opp = 14
Hyp = AB
Adj = BC
To find AB, apply SOH:
Sin 37 = Opp/Hyp
Sin 37 = 14/AB
AB = 14/Sin 37
AB = 23.262962 ≈ 23.3 (nearest tenth)
To find BC, apply TOA:
Tan 37 = Opp/Adj
Tan 37 = 14/BC
BC = 14/Tan 37
BC = 18.5786275 ≈ 18.6 (nearest tenth)

Step-by-step explanation:
for every one rotation a small gear takes, the larger gear makes 1/6 of a rotation. If the gear makes 10 complete rotations, how many rotations will the larger gear have made
Answer:
Step-by-step explanation:
1 and 2/3 rotations. The little gear full rotation is equal to 1/6 of the big gears rotation. So if the big gear rotates once then its equal to 6 of the small rotations the extra 4 of the 10 rotations then becomes 4/6 of the big gears rotation or if simplified further, 2/3. This is my way of solving these questions

Heaven is making bracelets. Each bracelet consists of 2.2 ounces of beads, and the
rest of the weight is made up of wire. If Heaven makes 2 bracelets that have a total
weight of 6.8 ounces, what is the weight of wire in each bracelet?
Answer:
1.2 ounces of each bracelet is made up from wire.
Step-by-step explanation:
2.2 x 2 = 4.4
6.8 - 4.4 = 2.4
2.4 / 2 = 1.2

Divide 104 by 32: 3.25 or 3 1/4
You think (claim) that the average franchise investment information shown in
the graph above is incorrect, so you randomly select 30 franchises and
determine the necessary investment for each. The sample mean investment is
$135,000 with a standard deviation of $30,000. Is there enough evidence to
support your claim at a = 0.05?
Using t-test, there isn't an enough evidence to support our claim that investment average is $135,000 at α = 0.05.
What is t - test?The one sample t test compares the mean of your sample data to a known value (population mean in our question, i.e. , we wish to compare the sample mean with the population mean). One sample t test should be used when you the population standard deviation is not known or the sample size is very small.
Assumptions of the t-test for the test to be valid:-
Data is independent.Data is collected randomly. For example, with simple random sampling.The data is approximately normally distributed.Null hypothesis: μ = $143,260
Alternative hypothesis: μ < $143,260
Calculating test statistic.
n = 30
sample mean = $135,000
sample standard deviation = $30,000
[tex]t_{0} = \frac{sample\ mean - population\ mean}{\frac{standard\ deviation}{\sqrt{sample\ size} } }[/tex]
[tex]t_{0} = \frac{135000 - 143260}{\frac{30000}{\sqrt{30} } }[/tex]
|to| = 1.508
Test criteria:

t(0.05, 29) = 1.6991
Since, |to| = 1.508 < t(0.05, 29) = 1.6991, null hypothesis cannot be rejected.

Which translation vector moves every point of a pre-image 4 units left and 6 units up?
F. (4, -6)
G. (-4, 6)
H. (-6, 4)
J. (6, -4)
Answer:
G(-4,6)
Step-by-step explanation:
Here, we want to write a translation
moving left means we are to subtract the number of units from the original
So we have this as -4
Moving up means we are to add the number of units to the original
So we have this as +6 = + 6 units
So the answer here will be;
(-4,6)
G. (-4, 6).
Given translation is 4 units left and 6 units up.
For left we use negative sign. And for up was use plus sign.
So the translation vector is (-4, 6).

91 is 82% of what number?
Answer:
110.97561
Step-by-step explanation:
82% of n = 91
82/100 × n = 91
41/50 × n = 91
n = 4550/41
4550/41 = 110.97561
Answer:
110.98
Step-by-step explanation:
82% of n = 91
82/100 × n = 91
41/50 × n = 91
n = 4550/41
4550/41 = 110.97561
round your answer and you will get 110.98.
if you place a 36-foot ladder against the top of a building and the bottom of the ladder is 32 feet from the bottom of the building, how tall is the building?
Answer:
16.49 feets
Step-by-step explanation:
Using Pythagoras rule, we could find, h the height of the wall ;
Using the relation :
a² = b² + c²
36² = h² + 32²
1296 = h² + 1024
h² = 1296 - 1024
h² = 272
h = √272
h = 16.49 feets
Which statement is true about the diameter of a circle?
The diameter has 3 endpoints.
The diameter is one half the length of a radius.
The diameter must pass through the center of the circle.
A diameter is not a chord.
A diameter is a type of radius.
Answer:
The diameter must pass through the center of the circle.
Step-by-step explanation:
TRUE STATEMENT :
The diameter must pass through the center of the circle.
Answer:
A. Both chords and diameters have two endpoints on a circle. Diameters must intersect the center of a circle.
Step-by-step explanation:
The only way to answer this question is to check the definitions of chord and diameter.
A chord is a segment with endpoints on the circle. In the attached figure the segments CD and GH are chords.
Now, notice that according to the given definition the segment EF is also a chord, but with the special characteristic that the center of the circle, denoted by A, it is on the segment. This ‘‘special’’ chords that contains the center of the circle are called diameter.
Sometimes the diameters are also called the larger of the chords.

PQR is an isosceles triangle with PR = PQ.
(5x -4°
(x + 52)
Calculate the value of y.
Answer:
Step-by-step explanation:
As two sides are equal so angles opposite to these are also equal, hence
5x-4=x+52
4x=56
X=14
Now,
R=5x-4
R=66
And,Q=x+52
Q=66(we already knew both angles are equal)
Now as sum of all angles of triangle equal 180 so,
66+66+P=180
P=48

Isaac exits his house and walks 2.3 miles south. Then, he turns and walks 4.5 miles east. How far away is Isaac from his house? Round your answer to the nearest tenth and label your answer. The labelling answer is miles
Answer:
5 miles
Step-by-step explanation:
2.3 miles south
then 4.5 miles east
a^2 + b^2 = c^2
a = 2.3 miles
b = 4.5 miles
(2.3)^2 + (4.5)^2 = c^2
c^2 = 25.54
[tex]\sqrt{c^2}[/tex] = [tex]\sqrt{25.54}[/tex]
c = 5.0
