You want to build a structure with a length of 5 m, where the proportions of other dimensions are conserved. Estimate the scale factor, 10 cm / 5 m = 0.02 .
How do you figure out the scale factor?The scale factor is a number that represents the ratio of the measurements of two similar figures, such as geometric shapes or maps. To find the scale factor, you can compare corresponding side lengths or angles of the two figures. The scale factor is the ratio of the length of a side in one figure to the corresponding side in the other figure. You can also find the scale factor by taking the square root of the ratio of the areas or the ratio of the volumes of the two similar figures.
Once you have the scale factor, you can use it to find the missing measurements of a similar figure by multiplying any measurement of one figure by the scale factor. In summary, the scale factor is a numerical value that allows to relate the measurements of two similar figures.

AKAJAXOSPAPXODAOAPA HELP
Answer:
He used 6 bananas at .50 which cost $3.00
12 oranges at .75 which cost $9.00 and
3 papayas at $1.25 which cost $3.75
Step-by-step explanation:
We can set up a system of equations using the information given.
b for banana, r for orange, p for papaya
b + r + p = 21. Also given r = 2b So substitute to simplify for calculating two unknowns:
b + 2b + p = 21 The number of items.
50b + 75(2b) +125p = 1575 The cost.
I multiplied everything by 100 to eliminate the decimals.
To solve by substituion, rewrite the first equation to get a value for p in terms of b
p = 21 - 3b
Substitute this value in the second equation and solve for b.
50b + 150b + 125(21–3b) = 1575
200b +2625 –375b = 1575 Subtract 2625 from both sides and combine the like terms:
–175b = 1575 –2625
–175b = –1050. Divide both sides by –175
b = 6
Substitute in the original equation to find the amount of each fruit:
b + r + p = 21
b = 6 bananas
r = 2b. 2(6) = 12 oranges. I used r so as not to mix up o with 0.
6 + 12 + p = 21
p = 21 –18
p = 3 papayas

if the measure of angle 1 = 17x - 30 and the measure of angle 2 = 7x + 18, what is the value of x?
Answer:
do you know the answer
The value of x is 4.8.
Given that,
The measure of angle 1 = 17x - 30 and the measure of angle 2 = 7x + 18.Based on the above information, the calculation is as follows:
Angle 1 = ANgle 2
17x - 30 = 7x + 18
17x - 7x = 18 + 30
10x = 48
x = 4.8
Therefore we can conclude that the value of x is 4.8.

Answer:
For Question 13 :∡ 1 = 130°; ∡ 2 = 50° ∡ 3 = 130°
For Question 14 :∡ 1 = 65°; ∡ 2 = 115° ∡ 3 = 65°
Step-by-step explanation:
Question 13:
There is multiple ways to solve those questions. However I will stick with the simple way.
1) We know that a straighteangle is = to 180°
2) Acording to the statment on step one we will say that ∡ 1 + the ∡ 50° = 180°
Resoectivelly
180° - 50° = ∡1
180° - 50° = 130°
∡ 1 = 130°
3) ∡ 2 + ∡ 1 = 180°
We already ∡ 1 from step 2, then
∡ 2 = 180° - 130°(∡1)
∡ 2 = 50°
4) ∡ 2 + ∡ 3 = 180°
∡ 3 = 180° - 50° (∡ 2)
∡ 3 = 130°
Question 14 1) We know that a straighteangle is = to 180°
2) Acording to the statment on step one we will say that
angle 1 + the angle 115° = 180°
Resopectivelly
180° - 115° = ∡ 1
180° - 50° = 65°
∡1 = 65°
3) ∡ 2 + ∡ 1 = 180°
We already∡ 1 from step 2, then
∡ 2 = 180° - 65°(∡1)
∡ 2 = 115°
4) ∡ 2 + ∡ 3 = 180°
∡ 3 = 180° - 115° (∡ 2)

Step-by-step explanation:

Combined:
2.67 times 23.76 = 63.4392
2.67 times - 21 and 5/6 = -58.295
63.4392 - 31.85 -58.295 = -26.7058
If you mean do both separate:
63.4392 - 31.85 = 31.5892
-58.295 - 31.85 = -90.145
B.
Combined:

Jared made 12 3 fourhs cups of snack mix for a party his guests ate two thirds of the mix how much snack mix did his guests eat
Answer: Jared guests ate = 8 1/2 cups of the snack mix.
Step-by-step explanation:
Total snack mix made by Jared = 12 3/4 CUPS
Amount eaten by guests = 2/3 of Total snack mix
which means they ate = 2/ 3 x12 3/4
= 2/3 x 51/ 4
=17/2 = 8 1/2 cups of snack mix.
Jared guests ate 8 1/2 cups of the snack mix.

A small plane flying from Los Angeles to San Diego averaged 175 mph with a tailwind. On the return trip with headwind the average speed was only 125 mph. Write and solve a system to reflect this relationship. Find the speed of the headwind/ tailwind AND the speed of the plane on a calm day.
Answer: System of equations:
p + w = 175
p - w = 125
p is the plane's speed, w is the wind speed
The wind speed is 25 mph. The plane's speed on a calm day is 150 mph.
Step-by-step explanation:
Solve by elimination: Add the equations. w "cancels" solve for p:
p + w = 175
p - w = 125
2p = 300 divide both sides by 2
p = 150 the plane's speed
Substitute 150 for p and solve for w
150 + w = 175 Subtract 150 from both sides.
w = 25 the wind speed

Step-by-step explanation:
We have a picture and are being asked to identify the multiplication problem that represents it.
So we have 5 triangles, all of which are color-coded in red, but only half of them are filled. When multiplying, the number that is before the * sign is the amount there is, while the number that is after the * is the amount going to multiply the amount of items there are. So looking at the picture, we can see 5 triangles, therefore :
5 *
2 * 1/5 is scratched out as an answer. As is starts with 2.
As for the second number, we acknowledge that all triangles are half in red, therefore the number is 1/2.

\angle a∠aangle, a and \angle b∠bangle, b are complementary angles. \angle a∠aangle, a measures 59^\circ59
∘
59, degrees.
What is the measure of \angle b∠bangle, b?
Answer:
31°
Step-by-step explanation:
because angle a and angle b are complementary they equal 90 degrees in total
a+b=90
since angle a = 59°
59+b=90
so you use subtraction property of equality and subtract 59 from both side of the equal sign
59+b=90
-59 -59
b= 31°

Answer:
p = 3.5 or p = 7/2
Step-by-step explanation:
-4p+9= -5
or, -4p = - 14
or, p = -14/-4
or, p = 7/2 = 3.5
Answer:
p = 3.5
Step-by-step explanation:
What you would do to get p is subtract 5 from both sides of the equation to leave the number and p, THEN divide both sides by the numerator of -4.
-4p + 9 = -5
- 9 -9
__________
-4p = -14
__ __
-4 -4
Thus, p = 3.5
