En un mapa, un centimetro representa 10 km, si en ese mapa hay una
distancia de 25 centimetros entre dos puntos, ¿cuál es la distancia real
entre esos dos puntos? *
En Español :
1 centímetro → 10 kilómetros
25 centímetros → x
x = (10×25)/1
x = 250 kilómetros
¿cuál es la distancia real
entre esos dos puntos?
La distancia real entre esos dos puntos es de 250 kilómetros.
In English :
1 centimeters → 10 kilometers
25 centimeters → x
x = (10 × 25) / 1
x = 250 kilometers
What is the real distance between those two points?
The actual distance between these two points is 250 kilometers.
2. if ur right i’ll give brainliest
Answer:
Option B
Step-by-step explanation:
By the midsegment theorem,
"Midsegment of a trapezoid is half the sum of the parallel bases"
By this theorem,
y + 6 = [tex]\frac{1}{2}[(3y-7)+(y+3)][/tex]
2(y + 6) = (3y + y) +(-7 + 3)
2y + 12 = 4y - 4
2y - 4y = -12 - 4
-2y = -16
2y = 16
y = 8
Therefore, length of the midsegment = y + 6
= 8 + 6
= 14
Option B will be the answer.

What's the definition of a imagine in math
Answer:A pic with numbers i dont know.Or maybe you were talking about imaginemath
Step-by-step explanation:
if y varies inversely as x and y=23 when x=8 find y when x=4
EQUATION:
[tex]y = \frac{k}{x} [/tex]
––––––––
First, find the constant of variation k using the formula k=xy.
[tex]23 = \frac{k}{8} [/tex]
[tex]k = (8)(23)[/tex]
[tex]k = 184[/tex]
––––––––
Then, find y if x is equal to four using the formula y=184/x.
[tex]y = \frac{184}{x} [/tex]
[tex]y = \frac{184}{4} [/tex]
[tex]y = 46[/tex]

4. The solution is x = -1, y = -2
5. Both equations represent the same line and the system of equation has Infinitely many solutions
6. The system of equation represent two parallel lines, therefore, the system of equation has no solutions
Step-by-step explanation:
4. The given system of equation are;
y = -3·x - 5...(1)
y = 9·x + 7...(2)
Equating both values of y from the two equations, gives;
9·x + 7 = -3·x - 5
12·x = -5 - 7 = -12
x = -12/12 = -1
x = -1
y = 9·x + 7 = 9 × (-1) + 7 = -2
y = -2
5. y = -2·x - 5...(1)
6·x + 3·y = -15...(2)
Substituting the value of 'y' from equation (1) in equation (2), gives;
6·x + 3·y = 6·x + 3 × (-2·x - 5) = -15 = -15
Therefore, equations (1) and (2) are the same and has infinitely many solutions
6. y = -4·x + 3
8·x + 2·y = 8
Substituting the value of 'y' from equation (1) in equation (2), gives;
8·x + 2·y = 8·x + 2×(-4·x + 3) = 6
However, 8·x + 2·y = 8, therefore, equations (1) and (2) do not intersect and they have no common solution.
Graph the inequality on the number line.
g>2.75
First, you need to circle 2.75. You have to decide whether or not to shade it in. On this equation, you wouldn't, because the answer can't be 2.75. You can tell because its greater than, and not greater than or equal to. So leave the circle empty. Then, you have to decide which way to shade. On this equation, you would shade right simply because g has to be greater than 2.75. If it was less than, you would shade left. Hope this helped!!!
Draw out a number line. Make sure the numbers 2 and 3 are plotted on the number line. Between these two values, cut this area into 4 equal slices. After cutting into quarters, mark the 3rd quarter since 3/4 = 0.75, so this where the value 2.75 resides.
Plot an open circle at 2.75, then shade to the right. The open hole is to say "do not include this value as part of the solution set". So we're visually describing all values larger than 2.75
Refer to the diagram below.
Twice the sum of Paloma's age and 15 is 16 how old is Paloma
Answer:
-7, but it doesn't make sense bc age can't be a negative. But based on how this is said it sounds like -7
Step-by-step explanation:
paloma's age = p
2( p + 15 ) = 16
2p + 30 = 16
-30 -30
2p = -14

p = -7

Evaluate |-11| + |-7|.
-18
-4
4
18
Answer: D) 18
======================================================
Explanation:
|-11| simplifies to 11
|-7| simplifies to 7
Whatever is inside the absolute value, you just remove the negative and that's the result of that absolute value expression. It represents the distance on a number line. So for instance -11 is 11 units from 0, which is why |-11| = 11.
Overall,
|-11| + |-7| = 11 + 7 = 18

Find the value of x
A farmer planted corn in two different fields. He planted 500 seeds of regular corn in Field A and 500 seeds of experimental corn in Field B. At
harvest time, more ears of corn had grown in Field A than in Field B. The farmer concluded that more corn grew in Field A because of the type
of corn planted.
Choose two other possible variables that could have caused more corn to grow in Field A.
O A. the type of soil in the field
B. the cost per ear of the corn
c. the flavor of each type of corn
D. the amount of sunlight in each field
E. the amount of corn planted in each field
Answer:
A or D

Wat is the value of x 0.25 + 13= 4(x- 8
Answer:
x = 11.3125
Step-by-step explanation:
0.25 + 13 = 4(x - 8)
Distribute the 4 across the parentheses.
0.25 + 13 = 4x - 32
Combine the constants on the left side of the equal sign.
13.25 = 4x - 32
Combine all the constants by adding 32 to both sides.
45.25 = 4x
Divide by 4 to isolate the x.
45.25/4 = x
11.3125 = x
Check.
0.25 + 13 = 4(x - 8)
0.25 + 13 = 4(11.3125 - 8)
0.25 + 13 = 4(3.3125)
0.25 + 13 = 13.25
13.25 = 13.25
If you start with 2 tons and subtract 1, 750 pounds, what weight remains?
Answer:
2250
Step-by-step explanation:
2 tons = 4000
4000 - 1750 = 2250
Hope this helps!!!
2250 pounds of weight remains.
What is weight?The weight of an object exists as the force acting on the object due to gravity. Some standard textbooks determine weight as a vector quantity, the gravitational force acting on the object. Others describe weight as a scalar quantity, the magnitude of the gravitational force.
As we know that ,
1 tons = 2000 pounds
2 tons = 4000 pounds
therefore,
4000 - 1750 = 2250
