Answer:
m < X + m < Y < 90
Step-by-step explanation:
For the triangle XYZ, m∠Z > m∠X + m∠Y we see that because the total internal angles of a triangle is 180,m∠X + m∠Y < 90° is a true assertion
Option C is correct
What must be true about triangle XYZ?Generally, A triangle's major feature is its total internal angles as 180
Therefore
if m∠Z > m∠X + m∠Y this means that m<z must be greater than 90 degrees
This goes to show us that
m<X + m<Y < 90 because as we earlier mentioned the total internal angles of a triangle is 180 .
In conclusion, For the triangle XYZ
m∠X + m∠Y < 90° is a true assertion

The perimeter of a rectangle is 208 inches. The ratio
of its length to its width is 5:3. What are the
dimensions of this rectangle?
A. 60 in by 44 in
B. 65 in by 39 in
C. 68 in by 36 in
D. 72 in by 32 in
Answer:
65 in and 39 in respectively
Step-by-step explanation:
Let r be the common ratio; when we multiply both L and R by this common ratio, we'll get the actual length and actual width of the rectangle, Recalling that the formula for the perimeter of a rectangle is P = 2L + 2R, we get:
2(5r) + 2(3r) = 16r = 208 in
Then r = 208/16 = 13
Thus, the actual length is 5(13 in) and the actual width is 3(13 in.),
or 65 in and 39 in respectively.
As a check, calculate 65 in / 39 in; this comes out to 5:3, as required.

Please help me asap help. The other two options are 6 2/8 and 6 1/4
Answer:
6 1/2
Step-by-step explanation:
To double the recipe we would need to multiply all the ingredients by 2. But since it is asking about the peaches, we only need to multiply 3 1/4 by 2. First we make the 3 1/4 to an improper fraction. (multiply denom. by the 3 then add the numerator. then keep the same denominator). The improper fraction of 3 1/4 would be 13/4. Now we can multiply by 2. That would give us 26/4 which reduces to 13/2. To change this back to a mixed number, we divide 13 by 2. That would give us 6 with a remainer of 1. So our answer is 6 1/2. Sorry if it's confusing hope it helps :)

Step-by-step explanation:
A ride-sharing company claims that the cost of rides follows a Normal distribution with a mean of $10.52. After
paying for a ride from this company, a rider reports that his price is in the 85th percentile of all other riders' prices. If
this rider paid $15.93, what is the approximate standard deviation of this company's ride-sharing cost?
Answer:
$5.20
Step-by-step explanation:
According to the Z-Score chart, the 85th percentile has a z-score of 1.04 and if you put that in the z-score equation (15.93-10.52)/x=1.04. Solve for x and you get $5.20.
Each day a machine makes 500000 staples and puts them into boxes.
The machine needs 165 staples to fill a box.
How many boxes will be filled with the 500,000 staples?
Answer:3031 boxes will be filled with staples
Step-by-step explanation:
Given that the machine makes 500000 in a day
So total staples = 500000
Staples in a box = 165
In order to find how many boxes the machine will make, the total number of staples has to be divided by the number of staples in a box.
So,
[tex]number\ of\ boxes = \frac{Total\ staples}{Staples\ in\ a\ box}\\= \frac{500000}{165}\\= 3030.30[/tex]
As no staples can be left out of box, we will round off the number to next number.
So,
3031 boxes will be filled with staples
Answer:
3031 boxes

According to the WHO report, girls who are 2-years old have a mean head circumference of 47.18cm with a standard deviation of 1.40 cm. A two year old girl with Down's syndrome has a head circumference of 44.5 cm. Children with Down's syndrome typically have smaller heads, so this is not surprising. 1. Relative to the WHO data, what is this girls z-score? What does the z score tell us? 2. Using the WHO data in a normal model, what percentage of the girls has a head circumference that is smaller than the girl with Down's Syndrome?
Answer:
1. z = -1.91429
The z score tells us that the head circumference of the girl with the down syndrome ( 44.5 cm) is 1.91429 standard deviations below the mean or average head circumference
2. 2.7792%
Step-by-step explanation:
1. Relative to the WHO data, what is this girls z-score?
z score formula is:
z = (x-μ)/σ, where
x is the raw score = 44.5 cm
μ is the population mean = 47.18cm
σ is the population standard deviation = 1.40cm
z = 44.5 - 47.18/1.40
z = -1.91429
What does the z score tell us?
The z score tells us that the head circumference of the girl with the down syndrome ( 44.5 cm) is 1.91429 standard deviations below the mean or average head circumference
2. Using the WHO data in a normal model, what percentage of the girls has a head circumference that is smaller than the girl with Down's Syndrome?
z score = -1.91429
Probability value from Z-Table:
P(z =-1.91429) = P(x<44.5) = 0.027792
Converting to percentage = 0.027792 × 100
= 2.7792%

based on the graph, what are the rate of change and the y intercept of the line.
O the rate of change is 1/2 and the y-intercept is 1
O the rate of change is one and the y-intercept is 1/2
O the rate of change is 1/2 and the y intercept is -2
O the rate of change is 2 and the y intercept is 1
Answer:
The rate of change is 1/2 and the y-intercept is 1
Step-by-step explanation:
You can calulate the rate of change by picking two points on the graph and using the slope formula
(y2-y1)/(x2-x1)
so in this example you can use the points (2,2) represeting (x1,y1) and (4,3) representing (x2,y2)
When you plug into the slope formula you get:
(3-2)/(4-2) = 1/2 which is the slope.
The y-intercept is where the line intersects the y=axis and can be seen as the coordinate pair (0, #) where the # is the y intercept. From the graph you can see the y-intercept is 1, but you can aslo solve for the y-intercept using the slope-intercept equation:
y=mx+b
where b is the y-intercept and m is the slope.
so using a slope of 1/2 and a coordinate of (2,2) you get:
y-2=(1/2)(x-2)
y = (1/2x)-1+2
y = (1/2x) + 1
so now the equation is in slope-intecept form and you can see the slope is 1/2 and the y-intercept is 1

The answer is h=15
Step-by-step explanation:
3.5 h+4.5)= 57
Let's solve your equation step-by-step.
3.5h+4.5=57
Step 1: Subtract 4.5 from both sides.
3.5h+4.5−4.5=57−4.5
3.5h=52.5

Before 2017, smartphones by major manufacturers all had screens with a aspect ratio. In 2017, two major brands released phones with screens in an aspect ratio. However they still reported their screen size using the same diagonal length of the earlier phones, 5.8 inches. How did the change in aspect ratio affect the screen size, if at all?
Answer:
the question is missing the numbers, so I looked for a similar one and found that screens back in 2017 had a 16:9 ratio and since then it changed to 18.5:9 ratio
the area of the screen is b x a x 0.5
we can form triangles:
old aspect ratio (16:9):
a = 1.778b
h = √(a² + b²)
5.8 = √[(1.778b)² + b²]
5.8 = √(3.16b² + b²)
5.8² = 4.16b²
33.64 = 4.16b²
b² = 33.64 / 4.16 = 8.0865
b = √8.0865 = 2.8437
a = 2.8437 x 1.778 = 5.056
area = 2.8437 x 5.056 x 0.5 = 7.19 in²
new aspect ratio (18.5:9):
a = 2.0556b
h = √(a² + b²)
5.8 = √[(2.0556b)² + b²]
5.8 = √(4.2253b² + b²)
5.8² = 5.2253b²
33.64 = 5.2253b²
b² = 33.64 / 5.2253 = 6.4379
b = √6.4379 = 2.5373
a = 2.5373 x 2.0556 = 5.2157
area = 2.5373 x 5.2157 x 0.5 = 6.62 in²
the actual screen area decreased by 0.57 in² or 7.93%
Consider the equation 4x -5(2x +1) = ax + b If a= (-6) and b=0 how many solutions does this eqaution have
it has one solution. x=2/7. im pretty sure
Sarah is trying to run a certain number of miles by the end of the month. If Sarah is 80% of the way to achieving her goal and she has already run 40 miles, how many miles is she trying to run by the end of the month?
Answer: 50 miles
Step-by-step explanation:
Let the miles that she is trying to run by the end of the month be denoted by x.
Since she is 80% of the way to achieving her goal and she has already run 40 miles. This can be expressed as:
80% of x = 40
80/100 × x = 40
0.8x = 40
x = 40/0.8
x = 50
The miles that she is trying to run by the end of the month is 50 miles.
