Step-by-step explanation:
by linear pair
(2x+4)+(x+23)=180
2x+4+x+23=180
3×+27=180
3x=180-27
x=153/3
×=51
Answer:
Step-by-step explanation:
2x + 4 + x + 23 = 180 {linear pair of angles}
3x + 27 = 180
3x = 180 - 27
3x = 153
x = 153/3
x = 51°

Answer:
Below in bold.
Step-by-step explanation:
-6x + 3y = -7
The x intercepts occur when y = 0, so
-6x + 3(o) = -7
x = -7/-6
x = 7/6
So the x-intercept = (7/6, 0).
The y intercept:
-6(0) + 3y = -7
y = -7/3.
So the y-intercept = (0, -7/3.t).

Find the radius of a circle is the circumference is 50.24cm. (Hint: Use C=2 x pi x radius to work backwards. Use the following set up and solve for the radius: 50.24=2 x 3.14 x radius)
Answer:
r = 8 cm
Step-by-step explanation:
Circumference of circle = 50.24 cm
2πr = 50.24
2 * 3.14 * r = 50.24
\(r = \frac{50.24}{2*3.14}=\frac{5024}{2*314}\\\\\\\\\)

3. The ______ projection shows the size and shape of continents accurately but distorts water areas.
A. Conic
B. Mercator
C. Robinson
D. Interrupted
The correct answer is A. Conic projection.
A conic projection is a type of map projection created by projecting the surface of a globe onto a cone. The cone is then unrolled and flattened to create a two-dimensional map. Conic projections are best for mapping small areas, such as individual countries or states. They are also good for mapping areas that are located near the equator.
Conic projections show the size and shape of continents accurately, but they distort water areas. This is because the cone is tangent to the globe at one point, and the further away from that point you get, the more distortion there is.
Mercator projection is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator. This inflation is very small near the equator but accelerates with increasing latitude to become infinite at the poles.
Robinson projection is a map projection presented by American cartographer Arthur H. Robinson in 1963. It is a compromise projection that attempts to balance the distortions of area, shape, and distance. The Robinson projection is neither conformal nor equal-area, but it is pseudocylindrical, which means that the meridians are straight lines and the parallels are circles.
Interrupted projection is a type of map projection that is interrupted at regular intervals. This is done to reduce the distortion of the map. The most common type of interrupted projection is the Mercator projection, which is interrupted at the equator and the prime meridian

You are about to begin work on a swimming pool in your yard. The first step is to have a hole dug that is 5 yards long, 4 yards wide, and 8 yards deep. You will use a truck that can carry 15 cubic yards of dirt and charges $ 10 per trip. How much will it cost you to have all the dirt hauled away?
Answer:
$110
Step-by-step explanation:
First, find how many cubic yards of dirt will be dug up:
Use the volume formula, V = lwh
Plug in the values:
V = lwh
V = (5)(4)(8)
V = 160
Now, divide this by 15 to find how many trips it will take:
160/15
= 10.67
Round this to the nearest whole number:
10.67
= 11
Multiply this by 10 to find the price:
11(10)
= 110
So, it will cost $110 to have all the dirt hauled away
The cost will be equal to $110.

A square pyramid is shown:
What is the surface area of the pyramid?
A. 2.46 square feet
B. 8.76 square feet
C. 5.16 square feet
D. 1.56 square feet
Answer:
B.76 square feet
Step-by-step explanation:
SA=B+L
Answer: B) 8.76 square feet
=========================================================
Explanation:
The base is a square with side length 0.6 ft, so the base area is 0.6*0.6 = 0.36 square feet.
Each lateral triangular panel has base 0.6 ft and height 7 ft. The area of one triangle is 0.5*base*height = 0.5*0.6*7 = 2.1 square feet
So four of these triangles combined give a lateral surface area of 4*2.1 = 8.4 square feet. Add this onto the base area to get 8.4+0.36 = 8.76 square feet of total surface area.

giving brainlyest need anser Bud and his friends stopped at a local fast food restaurant after the football game Friday night. Bud ate a one-fourth pound cheeseburger and a large order of fries. The cheeseburger contained 30 grams of total fat. If the recommended daily allowance of total fat for a 2,000 calorie diet is 64 grams, what percent of the daily allowance did Bud have when he ate the cheeseburger? Show your work.
To find out what percentage of the daily allowance of total fat Bud had when he ate the cheeseburger, we first need to calculate how many grams of total fat he consumed, and then divide that by the recommended daily allowance, and finally multiply by 100 to get the percentage.
Bud ate a cheeseburger containing 30 grams of total fat. The recommended daily allowance of total fat for a 2,000 calorie diet is 64 grams. Therefore, we can calculate the percentage of the daily allowance that Bud had by dividing the amount of fat he consumed by the recommended daily allowance and then multiplying by 100:
Percentage of daily allowance = (30 / 64) x 100 = 46.875%
So, Bud had 46.875% of the recommended daily allowance of total fat when he ate the cheeseburger.
Answer:
46.875 %
Step-by-step explanation:
30 grams of fat out of 64 grams
30/64 =.46875
Change to percent form
46.875 %
I don't see how the word problem number relates to what the rectangular prism is showing??
The total mass of the prism is 28.08 lb
What is the weight of the block of gel?Here we have a rectangular prism and we know that its density is 54 lb per cubic foot.
Remember that:
mass = density*volume
Then we need to findn the volume of the rectangular prims.
Remember that a rectangular prism of length L, width W, and height H has a volume:
V = L*W*H
Here the volume will be:
V = 6in*6in*25in (The numbers on the prism are really small and im not sure if the numbers here are the correct ones).
V = 900 in³
And:
1 ft³ = 1728 in³
Changing the volume units to cubic foots:
V = (900/1728) ft ³ = 0.52 ft³
And then the mass is:
M = 0.52 ft³*54 lb/ ft³ = 28.08 lb

If there's addition, use subtraction to find the value.If there's subtraction, use addition to find the value.x(y) means to multiply x with y____________________________________________________
1. In the first problem, we need to subtract 1 from 9 since there is an addition:
9 – 1 = 8
Next, divide 8 by 2, and we get:
8 ÷ 2 = 4
This means that x = 4
Finally, check the answer by:
2(4) + 1 = 9
2. In the second problem, we need to subtract 3 from 19 since there is an addition:
19 – 3 = 16
Next, divide 16 by 4, and we get:
16 ÷ 4 = 4
This means that x = 4
Finally, check the answer by:
4(4) + 3 = 19
3. In the third problem, we need to add 2 with 7 since there is subtraction:
2 + 7 = 9
Next, divide 9 by 3, and we get:
9 ÷ 3 = 3
This means that x = 3

Answer:
A) solution 2 is more acidic than solution 1
Step-by-step explanation:
A chemist prepares two acid solutions:
Solution 1: 3 parts sulfuric acid to 7 parts water
Ratio of sulphur to water: 3/7 (3:7)
Solution 2: 4 parts sulfuric acid to 9 parts water
Ratio of sulphur to water: 4/9 (4:9)
___________________________________________________
Part A: (using ratios to determine which solution is more acidic)
First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.
Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63
Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63
Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.
Mathematical Line (Not sure what you would call this lol): 28 > 27
Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)
Equation of solution 1: y = 3/7x
Equation of solution 2: y = 4/9x
Please find attachment for graph.
Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)
