The height of a tower on a scale drawing is 28 centimeters. The scale is 2cm = 21m. What is the actual height of the tower?
Answer:
14
Step-by-step explanation:
Add 2 till you get 28
Or multiply 2 by the numbers till you get 28
and 2 x 14 = 28
and more stuff here (2 cm = 21m = 0.02m to cm = 2cm)
I'm sorry, if this is wrong.
If not... brainliest???? :))

Given Equation:-
[tex] \sf25 - 12 \div [(8 - 5) \times 1][/tex]
[tex] \\ \\ [/tex]
Step-by-step explanation:-
[tex] \\ [/tex]
[tex] \dashrightarrow \sf25 - 12 \div [(8 - 5) \times 1][/tex]
first write the equation so that you'll emit minor mistakes of writing wrong digits.
[tex] \\ [/tex]
[tex] \dashrightarrow \sf25 - 12 \div [(3) \times 1][/tex]
subtract 8 and 5 , which will give us result as 3
[tex] \\ [/tex]
[tex] \dashrightarrow \sf25 - 12 \div [3 \times 1][/tex]
open the brakets that contains 3.
[tex] \\ [/tex]
[tex] \dashrightarrow \sf25 - 12 \div [3][/tex]
multiply 3 with 1 which will result 3.
[tex] \\ [/tex]
[tex] \dashrightarrow \sf25 - 12 \div 3[/tex]
open the brakets of 3.
[tex] \\ [/tex]
[tex] \dashrightarrow \sf25 - \dfrac{12}{3} [/tex]
to make it easy to understand I have converted it into fraction form.
[tex] \\ [/tex]
[tex] \dashrightarrow \sf25 - \dfrac{2 \times 2 \times 3}{3} [/tex]
simplify 12 which is contained in numerator.
[tex] \\ [/tex]
[tex] \dashrightarrow \sf25 - \dfrac{2 \times 2 \times \cancel3}{\cancel3} [/tex]
as we can see after converting into fraction 3 is common both in numerator and denominator. So cancel ir.
[tex] \\ [/tex]
[tex] \dashrightarrow \sf25 - (2 \times 2)[/tex]
we no longer need the fraction as 3 is canceled.
[tex] \\ [/tex]
[tex] \dashrightarrow \sf25 -4[/tex]
multiply 2 with 2 which will result 4.
[tex] \\ [/tex]
[tex] \dashrightarrow \bf21[/tex]
finally after subtracting 25 and 4 , we got our answer as 21.

Answer: a
Step-by-step explanation:
2 was divided into a particular number. the quotient was then multiplied by 2, and 8 was taken from that product. if the previous operation resulted in -14, find the initial number.
please show work and answer
Answer:
(2/X ) * 2 - 8 = - 14
4/X = - 6

Izzo's Pizza sells four types of pizza crust. Last week, the owner tracked the number sold of each type, and this is what she found.
Type of Crust Number Sold
Thin crust 344
Thick crust 250
Stuffed crust 180
Pan style 301
Based on this information, of the next 2500 pizzas she sells, how many should she expect to be pan style? Round your answer to the nearest whole number. Do not round any intermediate calculations.
Answer:
700
Step-by-step explanation:
total pizza sold last week:
344 Thin crust 250 Thick crust 180 Stuffed crust 301 Pan style1075 pizzas.
there were 301 pan pizzas of 1075 total pizzas.
we expect that the ratio 301/1075 will stay the same for 2500 pizzas.
301/1075 = X/2500
Multiplying both sides by 2500 cancels on the right
2500 × (301/1075) = (X/2500) × 2500
2500 × (301/1075) = X
Then solving for X
X = 2500 × (301/1075)
X = 700
Therefore
301 : 1075 = 700 : 2500

One angle of a triangle measures 95°. The other two angles are in a ratio of 8:9. What are the measures of those two angles?
Answer:
40 degrees and 45 degrees
Step-by-step explanation:
If you subtract 95 degrees from a 180-degree triangle, you are left with 85 degrees. To proportionally split them, find two values that add to the same value. Since 40 and 45 make up 80 and they multiply by two to make 80:90, these are the two measures.
FInd the measure of angle
Answer:
67°
Step-by-step explanation:
[tex]180 - (32 + 81) = 67[/tex]
Sheryl earns money for college by walking dogs and by mowing lawns. She earns $3 for each dog she walks and $25 for each lawn she mows. Which expression can be used to determine the amount of money, in dollars, Sheryl earns from walking w dogs and mowing m lawns?
3w + 25m
3w + 25
28(w + m)
75(w +m)
Answer:
3W+25m
Step-by-step explanation:
This is because 3 dollars multiply by the number of dogs which is W plus 25 multiplied by the number of mows she lawned gives the total earning for her college that is why the equation is 3W+25m
[MA]:
3w + 25m = T

What is the image of the point (8, -3) after a rotation of 90 counterclockwise about the origin?
Answer:
(3, 8)
Step-by-step explanation: When turned 90 counterclockwise, (x,y) becomes (-y,x)
(8, -3) would then be (3, 8) since it is going from quad 4 to quad 1. The y-coordinate would also be inverse, so -3 becomes positive 3.

Answer:
I disagree with both Andre thinks exponents
are just a different way of writing
multiplication of two numbers. Elena
calculates 28 to the power of two rather than 2 to the power of 28.
Step-by-step explanation:
Correct because I have on answer key.
Answer:
I disagree with both Elena and Andre
Step-by-step explanation:
An exponents refers to a number of times the number is multiplied by itself. In other words, it is repeated multiplication, just like Elena said. However, 2 is the base, so it should be the one being multiplied, not 28.
