What is the solution of the equation 4.5+m=10
Answer:
The first thing that we need to do is subtract 4.5 from both sides because that would removed the 4.5 from the left side and leave us with m by itself. So we get the following [tex]m=5.5[/tex] and that is our solution.
Hope this helps! Let me know if you have any questions
Answer:
5.5
Step-by-step explanation:
to find additional value, subtract the known
[because 4.5 plus (+) a number (m) is equal to (=) 10, the number (m) must be equal to (=) 4.5 minus (-) 10.]
10 - 4.5 = 5.5
to find if this is correct, add it back
4.5 + 5.5 = 10
m = 5.5

Camile is packing seeds to send to her mother in law. She estimates that she needs a box with a volume of at least 6,856 cubic inches. Here are the boxes she has to choose from Option A Length: 13 inches, Width 12 inches, Height: 16 inches Option B Length: 18 inches, Width: 25 inches, Height: 16 inches Option C Length:12 inches, Width: 14 inches Height: 22 inches Option D Length: 20 inches, Width:22 inches, Height: 17 inches Which boxes con she choose?
Step-by-step explanation:
the volume of a box (or prism) is always
length × width × height
so, box A
13 × 12 × 16 = 2,496 in³
box B
18 × 25 × 16 = 7,200 in³
box C
12 × 14 × 22 = 3,696 in³
box D
20 × 22 × 17 = 7,480 in³
so, she can use B or D.

Combine like terms to answer the question.
Answer:
3r + 5
Step-by-step explanation:
by "combining like terms", this means that if we have, for example,
1 * x + 5 * x, we can factor this out to be x*(1+5) = 6 * x and the like terms (1x and 5x) are combined
thus, we have
-5r + 8r + 5
the "like terms" here are -5r and 8r because they both have an r attached to it. thus, we can set out to only factor the r in these two numbers, resulting in
-5 * r + 8 * r + 5 = r * (-5 + 8) + 5 = r * 3 + 5 = 3r + 5

What is the least possible measure of LAD What is the greatest possible measure of LADC?
Answer:
B. least 2°; greatest 178°
Step-by-step explanation:
The measure of ∠ADC will be the sum of the measures of the two acute angles ADB and BDC.
__
Each acute angle with a measure that is a whole number of degrees will have a measure between 1° and 89°, inclusive.
The least sum of two such angles will be ...
1° +1° = 2°
The greatest sum of two such angles will be ...
89° +89° = 178°
which of the following is the solution for the inequality below? -3x+2<8
Answer:
x>-2
Step-by-step explanation:
First you have to subtract 2 from both sides, which leaves you with -3x=6, then you have to divide -3 on both sides to get the variable by itself. Which is x<-2, but you have to switch the sign because you multiplied/divided by a negative number, then you get left with x>-2........Hope that helped!!!!!!!!!!:)

Taxi charges 2.95 for the first mile and 0.30 per 1/8 gary was charged 25.45 for this taxi ride. Not including the first mile how many miles did Gary travel.
Using proportions, considering the cost of the taxi per mile, it is found that Gary traveled 9.375 miles, not including the first.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the company charges 2.95 for the first mile and $0.3 per each 1/8 mile next = $2.4 per mile. After the first mile, he was charged a total of $25.45 - $2.95 = $22.5. Hence the number of miles is given by:
22.5/2.4 = 9.375.

One of the legs of a right triangle measures 12 cm and its hypotenuse measures 20 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
other leg = 16 cm
Step-by-step explanation:
using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the other leg , then
x² + 12² = 20²
x² + 144 = 400 ( subtract 144 from both sides )
x² = 256 ( take square root of both sides )
x = [tex]\sqrt{256}[/tex] = 16

Find the length of the curve r=sqrt(1 cos 2 theta)
The length of the curve r=√(1+cos 2θ) is 2π after integrating over the limit 0 to π√2
What is integration?It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.
We have:
[tex]\rm r=\sqrt{(1 +cos 2 \theta)}[/tex]
[tex]\rm r=\sqrt{2cos^2 \dfrac{2 \theta}{2}[/tex]
[tex]\rm r = \sqrt{2}cos\theta[/tex]
[tex]\rm \dfrac{dr}{d\theta}= -\sqrt{2}sin\theta[/tex]
Length:
[tex]\rm L = \int\limits^{\pi\sqrt2}_0 {\sqrt{r^2+(\dfrac{dr}{d\theta}})^2} \, d\theta[/tex]
After the value of r and dr/dθ and solve the definite integral, we will get:
L = 2π
Thus, the length of the curve r=√(1+cos 2θ) is 2π after integrating over the limit 0 to π√2

The length of the diagonal of the garden with 19.6 square feet and 4.3 length is : 6.3 feet
What is a rectangle?A rectangle is a quadrilateral with four sides and four vertices each of angle 90°.
Analysis:
Area of rectangle: 19.6 square feet
length of one side = 4.3 feet
width of one side = Area/length = 19.6/4.3 = 4.6 feet
the diagonal and width and length of a rectangle for a right angle triangle.
To find the diagonal, we use Pythagoras theorem
[tex](diagonal)^{2}[/tex] = [tex](length)^{2}[/tex] + [tex](width)^{2}[/tex]
[tex](diagonal)^{2}[/tex] = [tex](4.3)^{2}[/tex] + [tex](4.6)^{2}[/tex]
