If a number, a, rounded to 1 decimal point is 49.3. A number, b, rounded to 1 decimal point is 7.6 the upper and lower bounds of a-b is: 41.66; 41.79.
Upper and lower boundsGiven:
A= 49.3
B=7.6
Now let find the lower bounds and the upper bounds
Lower bounds is calculated as:
Lower bounds=a-b
Lower bounds=49.35-7.69
Lower bounds=41.66
Upper bounds is calculated as:
Upper bounds=a-b
Upper bounds=49.34-7.55
Upper bounds=41.79
Therefore If a number, a, rounded to 1 decimal point is 49.3. A number, b, rounded to 1 decimal point is 7.6 the upper and lower bounds of a-b is: 41.66; 41.79.

Choice 1- 2 red:3 yellowChoice 4- 28 red:42 yellowChoice 5- 44 red:66yellow.What are ratios?Ratios are quantitative measures of how much a variable is contained in another.
Ratios show numerical relationships between quantities.
Ratios are expressed as decimals, fractions, and percentages.
Data and Calculations:The mixture of red coloring = 4 drops
The mixture of yellow coloring = 6 drops
The ratio of red to yellow coloring = 4:6 or 2:3
Choice 1- 2 red:3 yellow = 2:3 (already simplified)
Choice 4- 28 red:42 yellow = 2:3 (when simplified by 14)
Choice 5- 44 red:66yellow = 2:3 (when simplified by 22)
Thus, the ratios of the food coloring drops that would create the same orange icing are Choices 1, 4, and 5.

The difference in the distances flown by these two birds after three hours of light is 94.47km
Distance graphAccording to the question, Evolve eagle flies 43.2 m, the distance it will fly in 3 hours will be;
43.2m = 3 seconds
x = 10800seconds
Find the ratio
3x = 43.2 × 10,800
x = 155520 meters = 155.530km
From the graph, the distance traveled in 3 hours is equivalent to 250km
Difference in distance

2. Kenzie makes $12.50 per hour. She works 20 hours per week. Find:
a. Her weekly pay
b. Her monthly pay
c. Her yearly pay
d. Her weekly take-home pay if she takes home 76%.
can someone explain?
Her weekly pay is $250
Her monthly pay is $1000
Her yearly pay is $12000
Her weekly take-home pay if she takes home 76% is $190
What is a unit rate?Unit rate is the ratio of two different units, with the denominator as 1.
We have,
1 hour = $12.50
1 week = 20 hours
The weekly pay:
= 20 hours
= 20 x 12.50
= $250
Monthly pay:
= 4 weeks
= 4 x 20 hours
= 80 hours
= 80 x 12.50
= $1000
Yearly pay:
= 12 months
= 12 x 4 weeks
= 48 weeks
= 48 x 20 hours
= 960 hours
= 960 x 12.50
= $12000
Weekly take-home pay:
= 76% of $250
= 76/100 x 250
= $190
Thus,
Her weekly pay is $250
Her monthly pay is $1000
Her yearly pay is $12000
Her weekly take-home pay if she takes home 76% is $190

If Ð1 and Ð2 are complementary angles, and mÐ1 = 74!; "nd mÐ2.
Answer:
∠ D2 = 16°
Step-by-step explanation:
complementary angles sum to 90° , then
∠ D1 + ∠ D2 = 90°
74° + ∠ D2 = 90° ( subtract 74° from both sides )
∠ D2 = 16°
If two angles are complementary they add up to a total of 90 degrees.
So we know that
D1+D2=90, because the problem tells us they're complementary
Now, we know as well that D1 = 74, so we can plug it into the little equation and solve in terms of D2.
[tex]D1+D2=90[/tex]
[tex]74+D2=90[/tex]
[tex]D2=90-74[/tex]

What is translation?
A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other.
Given that,
The translation is 1 units left and 5 units up.
The coordinates of the given figure are R(-3, -3), S(-3, -1), T(2, 0) and
U(1, -5).
Now, If the translation is 1 units left and 5 units up, then the coordinates become (x - 1, y + 5).
Hence, Coordinates for the image of the graph are;
R' = (-4 - 1, 2 + 5) = (-5, 7)
S' = (-3 - 1, -1 + 5) = (-4, 4)
T' = (2 - 1, 0 + 5) = (1, 5)
U' = (1 - 1, -5 + 5) = (0, 0)
Hence, The coordinates are R'(-4, 2), S'(-4, 4), T'(1, 5) and U' (0, 0).
Therefore, The figure with the coordinates R'(-4, 2), S'(-4, 4), T'(1, 5) and
U' (0, 0) are graph of the image of the figure.
Hence, Option B is the correct answer.

A delivery person has two different delivery routes that he follows the first route is 20.75 miles long and the second is 30.25 miles long he travels each route 4 times a week after 7 weeks how many total miles has he traveled
Answer:
Step-by-step explanation:
20.75 miles x 4 = 83 miles
30.25 miles x 4 = 121 miles
Now take the 83 and multiply by 7 for the 7 weeks and multiply the 121 also by 7.
83 x 7 = 581
121 x 7 = 847
Now add the 581 miles with the 847 to get the total miles travelled.
581+847 = 1428 Miles
Answer: The delivery person travels 1428 miles

find the general form of the quadratic function with the vertex (1,4) and a point on the graph (-3,20)
The general form of the quadratic function is x² - 2 · x - y + 5 = 0.
How to find the general form of the quadratic function
In this question we must derive the equation of the parabola in vertex form, whose description is shown below:
4 · p · (y - k) = (x - h)² (1)
Where:
(h, k) - Coordinates of the vertex.(x, y) - Coordinates of a point of the parabola.p - Distance from vertex to focus.If we know that (h, k) = (1, 4) and (x, y) = (- 3, 20), then the distance from vertex to focus is:
p = (x - h) / [4 · (y - k)]
p = (- 3 - 1)² / [4 · (20 - 4)]
p = (- 4)² / 64
p = 16 / 64
p = 1 / 4
Then, the equation of the parabola in vertex form is y - 4 = (x - 1)². And now we find the general form of the quadratic formula, that is:
A · x² + B · x + C · y + D = 0 (2)
Then, we proceed to obtain the general form:
y - 4 = (x - 1)²
y - 4 = x² - 2 · x + 1
x² - 2 · x - y + 5 = 0
The general form of the quadratic function is x² - 2 · x - y + 5 = 0.
