Cuál es la fuerza total que ejerce 3 personas empujando una carreta? F1 = 30 N, F2 = 45 N, F3 = 38 N?
Answers
Respuesta:
113 N
Explicación paso a paso:
Las fuerzas ejercidas se dan como:
F1 = 30 N
F2 = 45 N
F3 = 38 N
A partir de los valores de las fuerzas ejercidas, podemos observar que todas las fuerzas están en la misma dirección; Dado que la fuerza total ejercida es un sol de las 3 fuerzas:
F1 + F2 + F3
(30N + 45N + 38N) = 113 N

Work out the size of an exterior and an interior angle of a regular 16-sided
polygon.
Answers
Answer:
exterior angle: 22.5°, interior angle: 157.5°
Step-by-step explanation:
the formula for the measure of each Interior Angle in a regular polygon: [tex]\frac{180(n-2)}{n}[/tex], n = # of sides
=> [tex]\frac{180(16 - 2)}{16}[/tex] = 157.5°
the formula for the measure of each Exterior Angle in a regular polygon: [tex]\frac{360}{n}[/tex]
=> [tex]\frac{360}{16}[/tex] = 22.5°

Select an equation that is equivalent to a^2-144b^2 a) (a-12b)^2 B) (a+12b)^2 C) (a-12b)(a+12b) C) a^2-24ab+144b^2
Answers
Answer:
C) (a-12b)(a+12b)
Step-by-step explanation:
a^2-144b^2 = (a-12b)(a+12b)
This is the formula that when two terms squared are written with a minus sign between them their factors are the product of the original numbers once with a plus sign and once with the minus sign.
This can be explained by multiplying them.
(a-12b)
*(a+12b)
a²- 12ab
+12ab - 144b²
a² +0 - 144b²
We see we get the same answer as applying the formula above.

Find the shaded angle
Answers
Answer:
332°
Step-by-step explanation:
Given is an isosceles triangle,
Measures of base angles of an isosceles triangle are equal.
Therefore,
Measure of central angle
= 180° - ( 76° + 76°)
= 180° - 152°
= 28°
Measure of shaded angle
= 360° - 28°
= 332°

What is the value of BD
Answers
Well, by the segment addition postulate, 3x + 5 + 5x - 7 = BD, so BD = 8x - 2.
Because you didn't include the instructions in the picture, I can't be sure if this is a rhombus or a rectangle, but if it is either, then 3x + 5 = 5x - 7, and x = 6
If this is true, then BD = 48 - 2 = 46, but only if the shape is either a rhombus or rectangle (or both would make it a square).
The scatter plot shows the relationship between summer and winter temperatures. What is the range of the cluster shown in the

B)
58°F to 61°F average January high temperature
C)
91°F to 98°F average July high temperature
D)
94°F to 95°F average July high temperature
Answers
Answer:
D
Step-by-step explanation:
Since it's talking abtou clusters, the only "cluster" like part there is there is where 94 and 95 are, so it has to be D.
Using the scatter plot and the range concept, it is found that the correct option is:
C) 91°F to 98°F average July high temperature
The range of a data-set is the set that contains all possible output values.
In this problem, the average July temperature is the output, plotted as function of the average January temperature, which is the input.
It varies from 91ºF to 98ºF, hence, the correct option is:C) 91°F to 98°F average July high temperature

A population of 2500 frogs increases exponentially at an annual rate of 25%. Which equation below best represents the population (P) in t years?
P=2500(0.25)^t
P=2500+0.25t
P=2500(0.75)^t
P=2500(1+0.25)^t
Answers
Answer:
P=2500(1+0.25)
Step-by-step explanation:
Given data
Initial population= 2500
Rate= 25%
The exponential increase is described using the expression
P=A(1+r)^t
Hence the correct representation is
P=2500(1+0.25)
