Sara y Oscar pintaron una pared de 40m2, Si sara pinto 2700dm2 de la pared, ¿Cuántos metros cuadrados pinto Oscar
Answer:
Oscar pintó 13 m².
Step-by-step explanation:
Sara y Oscar pintaron una pared de 40m². Sara pintó 2700 dm² de la pared. En primer lugar, es conveniente realizar una conversión de unidades. Para eso aplicas la siguiente regla de tres: si 1 dm² equivale a 0.01 m², entonces 2700 dm² ¿a cuántos m² equivalen?
[tex]m^{2} =\frac{2700dm^{2}*0.01m^{2} }{1dm^{2} }[/tex]
m²= 27
Entonces 2700 dm² equivalen a 27 m². Esto indica que Sara pintó 27 m² de la pared. Entonces, para calcular la superficie que debió pintar Oscar simplemente haces la diferencia entre los m² totales de pared y los m² pintados por Sara:
40 m² - 27 m²= 13 m²
Oscar pintó 13 m².

Max:
99 - 31 = $68 remaining
68 / 8.5 = 8 weeks
Sharifa:
99 - 25.5 = $73.50 remaining
73.5 / 10.5 = 7 weeks
How do I solve for x??
Step-by-step explanation:
W.K.T angle of a straight line is 180°.
40°+2x+30°+40°=180°
110°+2x=180°
2x=180°-110°
2x=70°. x= 70°/2=35°
X=35°

What is the slope of the line through (-1,8)(−1,8)left parenthesis, minus, 1, comma, 8, right parenthesis and (3,-4)(3,−4)left parenthesis, 3, comma, minus, 4, right parenthesis?
Answer:
The slope of the line through (-1, 8) and (3, -4) = m = -3
Step-by-step explanation:
Given the points
(-1, 8)(3, -4)Determining the slope between (-1, 8) and (3, -4)
(x₁, y₁) = (-1, 8) (x₂, y₂) = (3, -4)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [-4 - 8] / [3 - (-1)]
= [-12] / [3+1]
= -12/4
= -3
Thus, the slope of the line through (-1, 8) and (3, -4) = m = -3
Answer:
The answer is -3
Step-by-step explanation:
Slope = Rise/Run = Change in y/Change in x
Slope = (-4 - 8) / (3 - -1)
= -12/4
= -3
So, the answer is -3
Hope this helps! :)

If m∠2 = 120°, what is m∠7?
Answer:
120°
Step-by-step explanation:
They are alternate exterior angles, so they're congruent
As ∠2 and ∠7 are pairs of alternate angles m∠7 is also 120°
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are the same and the measure of alternate angles is also the same and the pair of adjacent forms an angle of 180°.
Given are two lines that are parallel to each other and intersected by a transversal.
Also given that m∠2 = 120° and we can conclude that ∠7 is an alternate angle to it.
∴ m∠7 is also 120°.

A population of 70 foxes in a wildlife preserve doubles in size every 13 years. The function y = 70.2*, where x is the number of 13-year
periods, models the population growth. How many foxes will there be after 26 years?
After 26 years there will be how many foxes. (Type a whole number.)
Answer: After 30 years there will be 4480 foxes.
Step-by-step explanation:
first period: (4) x (70) = 280
second period: (4) x (280) = 1120
