2× 22=44÷4=6/4 o 6.4 6.4=44. ×2 x=6.4
You are given that a = 6.54 (to 3 significant figures) and b = 123 (to 3 significant figures).
Calculate upper and lower bounds for each of the following, give your answers to 3 significant figures:
(a) a + b
(b) ab
(c) a/b
(d) b - 1/a
The upper and lower bounds for the numbers are illustrations of approximation
How to calculate the upper and lower boundsThe numbers are given as:
a = 6.54 (to 3 significant figures)
b = 123 (to 3 significant figures)
(a) a + b
We have:
a + b = 6.54 + 123
a + b = 129.54
When approximated, the bounds to three significant digits are:
Lower bound = 129
Upper bound = 130.1
(b) ab
We have:
ab = 6.54 * 123
a + b = 804.42
When approximated, the bounds to three significant digits are:
Lower bound = 804
Upper bound = 805
(c) a/b
We have:
a/b = 6.54/123
a/b = 0.0531707317
When approximated, the bounds to three significant digits are:
Lower bound = 0.0531
Upper bound = 0.0532
(d) b - 1/a
We have:
b - 1/a = 123 - 1/6.54
b - 1/a = 122.847094801
When approximated, the bounds to three significant digits are:
Lower bound = 122
Upper bound = 123

MN is 6 units. Find the lengths of NZ and XZ.
For the image see if you have enough info to find the missing lengths. If not, explain why.
Answer:
Step-by-step explanation:
[tex]\frac{3 +NZ}{3}[/tex] = [tex]\frac{5+5}{5}[/tex] ⇒ NZ = 3
XZ = 6 × 2 = 12
The length of NZ = 3 units.
The length of XZ = 12 units
Triangle Proportionality TheoremWhat is Triangle Proportionality Theorem?A line that runs perpendicular to one side of a triangle and crosses the other two sides equally splits the two sides.
Use of Triangle Proportionality Theorem to find the sides:Step 1: Consider side NY, NZ, YM, MX
By the theorem,
[tex]\frac{YN}{NZ}=\frac{YM}{MX}[/tex]
[tex]\frac{3}{NZ}=\frac{5}{5}[/tex]
[tex]NZ=3[/tex] units
Step 2: Consider sides YM, YX, NM, ZX
[tex]\frac{YM}{YX} =\frac{NM}{ZX}[/tex]
[tex]\frac{5}{10} =\frac{6}{ZX}[/tex]
[tex]ZX = 12[/tex] units.
Therefore, the values for the sides are NZ = 3 units and XZ = 12 units.

Is 2750 a reasonable answer for 917 * 33 explained
Answer:
No
Step-by-step explanation:
To make this simpler, we will round each number. 917 rounds to 900 and 33 rounds to 30. 900 * 30 = 27,000. We can do this in our head because 9 * 3 = 27, and there are three zeros total between 900 and 30, so we add three zeros after 27. 2750 is not a reasonable answer because the true answer is about 10 times greater than 2750.

Answer:
[tex]x=\frac{12}{5}[/tex]
[tex]x=2.4[/tex]
Step-by-step explanation:
[tex]6x+2\left(2x-3\right)=18[/tex]
Expand 2(2x-3) by applying Distributive law:
[tex]2\times \:2x-2\times \:3[/tex]
Multiply:
[tex]2\times \:2x=4[/tex]
[tex]2\times \:3=6[/tex]

[tex]6x+4x-6=18[/tex]
Combine like terms:
[tex]6x+4x=10x[/tex]
[tex]10x-6=18[/tex]
Add 2 to both sides:
[tex]10x-6+6=18+6[/tex]
[tex]10x=24[/tex]
Divide both sides by 10:
[tex]\frac{10x}{10}=\frac{24}{10}[/tex]

[DUE TOMORROW] Answer using steps: A truck sprang a leak in its radiator, which held 480 ounces of fluid when it started to leak. Assuming the truck continues at 35 mph and it’s radiator leaks 4 ounces of fluid per minute, how many miles will the truck travel before the radiator is empty
Answer
It will make it 70 miles because it leaks 4 ounces every minute so divide 480 by 4 and get 120 with would be for how many minutes you would be able to drive with the leak. So convert minutes to hours and you get 2 hours and every hour you go 35 miles so multiply 35 by 2 and you get 70.

Use f(x) = 2x − 3 and g(x) = 4 − x2 to evaluate the expression.
(a) (f ∘ g)(x)
(b) (g ∘ f)(x)
The resulting expressions for [tex](f\,\circ\,g)(x)[/tex] and [tex](g\,\circ\,f)(x)[/tex] are [tex]5- 2\cdot x^{2}[/tex] and [tex]-4\cdot x^{2} + 12\cdot x -5[/tex], respectively.
A composition is a operation two functions in which the independent variable of the first function is substituted by the entire second function. In other words, we have the following expressions:
[tex](f\,\circ\,g) (x) = f(g(x))[/tex] (1)
[tex](g\,\circ \,f)(x) = g(f(x))[/tex] (2)
If we know that [tex]f(x) = 2\cdot x - 3[/tex] and [tex]g(x) = 4 - x^{2}[/tex], then we have the following compositions:
[tex](f\,\circ\, g) (x) = 2(4-x^{2})-3[/tex]
[tex](f\,\circ\,g)(x) = 5-2\cdot x^{2}[/tex]
[tex](g \circ f) (x) = 4 - (2\cdot x-3)^{2}[/tex]
[tex](g\,\circ f) (x) = -4\cdot x^{2} +12\cdot x -5[/tex]
The resulting expressions for [tex](f\,\circ\,g)(x)[/tex] and [tex](g\,\circ\,f)(x)[/tex] are [tex]5- 2\cdot x^{2}[/tex] and [tex]-4\cdot x^{2} + 12\cdot x -5[/tex], respectively.

Reaserch how x ray technications use math in their careers
Answer:
X-ray technicians, also referred to as radiologic technologists, would need math skills to be able to use accurate calculations when mixing chemicals used in x-ray imaging processes. In addition to this, the critical and logical thinking abilities practiced in the study of mathematics are useful in the day to day job, especially because working with imaging technology and machines to get detailed images for physicians to view is crucial to patient care and treatment.
Education for an associate's degree in radiologic technology is going to be focused heavily on STEM related courses such as anatomy, radiation safety, imaging procedures, and pathology. For this reason, it is recommended that high school students planning on pursuing this educational path take plenty of classes in math, science, and technology.
Radiologic technology job opportunities are expected to increase by 9 percent between 2018 and 2028 according to the Bureau of Labor and Statistics. This is greater than the 5 percent average increase projected for all other jobs, which means radiological technology is a career with a strong and stable outlook.
