Answer:
41/35
Step-by-step explanation:
Simplify the following:
4/7 + 3/5
Put 4/7 + 3/5 over the common denominator 35. 4/7 + 3/5 = (5×4)/35 + (7×3)/35:
(5×4)/35 + (7×3)/35
5×4 = 20:
20/35 + (7×3)/35
7×3 = 21:
20/35 + 21/35
20/35 + 21/35 = (20 + 21)/35:
(20 + 21)/35

5. Dos edificios distan entre si 150 metros. Desde un punto que está entre los dos edificios, vemos
que las visuales a los puntos más altos de estos forman con la horizontal ángulos de 35° y 20
¿Cuál es la altura de los edificios, si sabemos que los dos miden lo mismo?
Answer:
35.92 m
Step-by-step explanation:
To have a better comprehension of the problem, we can draw it as in the image attached.
If we use the tangent relation in both triangles, we have:
tangent(35) = h/x
tangent(20) = h/(150-x)
From the first equation, we have:
x = h/tangent(35) = h/0.7
From the second equation, we have:
0.364 = h / (150 - h/0.7)
54.6 - 0.52h = h
1.52h = 54.6
h = 35.92 m

Find the slope
Use this form for example:y=Mx+b
Answer:
Line: y = Mx + b, passes (0, 1) => M*0 + b = 1 => b = 1
Line: y = Mx + 1, pass (2, 4) => 2M + 1 = 4 => M =3/2
=> Line: y = (3/2)x + 1

Which one belong doesn't? Which angle does not belong with the other three? Explain your reasoning. Please help, thank you.
a) -90 degrees b) 450 degrees
c) 90 degrees d) -270 degrees
Answer:
450 degrees
Step-by-step explanation:
There is no angle that can possibly be 450 degrees. Angles go as far a 360 degrees and then stop.
What is m wtv in degrees
We have been given image of a circle. We are asked to find the measure of angle WTV.
We know that measure of an inscribed angle is half the measure of intercepted arc.
We can see that angle WTV is inscribed angle to arc WV. So measure of angle WTV will be half the measure of arc WV.
[tex]\angle WTV=\frac{1}{2}\widehat{WV}[/tex]
[tex]\angle WTV=\frac{1}{2}\cdot 90^{\circ}[/tex]
[tex]\angle WTV=45^{\circ}[/tex]
Therefore, the measure of angle WTV is 45 degrees and 2nd option is the correct choice.

Answer:
1.3
Step-by-step explanation:
BC is the distance between B and C.
BC = x − (-0.4)
BC = x + 0.4
AB is the distance between A and B.
AB = -0.4 − (-1.25)
AB = -0.4 + 1.25
AB = 0.85
Substitute into the equation.
BC = 2AB
x + 0.4 = 2(0.85)
x + 0.4 = 1.7
x = 1.3
Answer:
x=1.3
Step-by-step explanation:
AB=(-0.4-(-1.25))=1.25-0.40=0.85
BC=2AB=2×0.85=1.70
x=-0.4+1.7=1.3

What is the perimeter of this shape?
Answer:
87 feet
Step-by-step explanation:
Two of the sides here are unknown. The one on the leftmost side is equal to 9, since on the other side it also has a length of 9 feet. The section on the top right has a length of 30-9-9=12 units. Adding all of these values together now, you get a total perimeter of:
30+9+12+9+9+9+9=87 feet
Hope this helps!
Answer:
The perimeter of this shape is 87 ft.
Step-by-step explanation:
Given that all side lengths are added together in order to find perimeter. So the perimeter is :
[tex]perimeter = 9 + 9 + 9 + 12 + 9 + 30 + 9[/tex]
[tex]perimeter = 45 + 30 + 12[/tex]
[tex]perimeter = 87 \: feet[/tex]
Annalise earns $4 an hour walking pets in her neighborhood. She evaluates the expression 4h, where h represents the number of hours, to find the amount she earns. Can any number be substituted for h?Expain.
Answer:
Yes any number can be substituted for h
Step-by-step explanation:
The term 'h' is an independent variable any number can be substituted for h, so long as the number represents the hours worked
So if she walks pets for 8 hours
Her pay is 4*8= $32

The blank words are:
Enlargement and 6.4.
What is a scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
Given:
A company plans to scale its logo and place it on a billboard so that drivers and pedestrians can see it easily from the ground.
The original logo is a square with sides of 1.25 inches.
After scaling,
the local must have a perimeter of 32 feet.
This action is called enlargement,
and the scale factor is,
= (32/4) / 1.25
= 8 / 1.25
= 6.4.
Therefore, the scale factor is 6.4.

Find composite function
Answer:
1 / (99 - 40x).
Step-by-step explanation:
The whole of g(x) is input to f(x), so:
we replace the x in f(x) by g(x).
f(g(x)) = 1 / [8(12 - 5x) + 3]
= 1 /( 96 - 40x + 3)
= 1 / (99 - 40x).
The first three terms of a Fibonacci sequence are n 3n 4n find the sixth term I FB the sequence
Answer:
18nStep-by-step explanation:
In the Fibonacci sequence In mathematics, the Fibonacci numbers, commonly denoted [tex]Fn[/tex], form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1.
Given data
First term= n
second term = 3n
third term = 4n
According to Fibonacci sequence the fourth term is
[tex]F4= F2 + F3\\F4=3n+ 4n= 7n[/tex]
the Fifth term is
[tex]F5= f3 + f4\\f5= 4n+7n= 11n[/tex]
hence the sixth term is
[tex]F6= F4+F5\\ F6= 7n+11n= 18n[/tex]
Two boats A and B Left a Port at the same time on different routes . B travelled on a bearing of 150º and A travelled on the North side of B . When A had travelled 8km and B had travelled 10km, the distance between the two boats was found to be 12km . Calculate the bearing of A's route from C.
Answer: 67.2°
Step-by-step explanation:
To find angle C, we have to use cosine rule. Therefore,
12² = 8² + 10² - 2 × 8 × 10 × cosC
C = 82.8°
The bearing of A from C will be
= 150° - 82.8°
= 67.2°.
