-1/4a - 4 = 4
Answer:
a = -12
Step-by-step explanation:
-1/4a - 4 = 4
(-1/4a / -1/4) - 4 = (4 / -1/4)
a - 4 = -16
(a - 4 + 4) = -16 + 4
a = -12

The top line tells you this two figure is similar.
What does this mean? Similar figures have the exact same corresponding angles and proportionate sides.
You can find their side ratio with 38 and 15.2.
38 ÷ 15.2 = 2.5
To find x, use 55 ÷ 2.5 and you get 22 as your answer.

2x² + 5x - 42 = 0 * PLEASE SHOW YOUR WORK *
Answer:
x = - 6, x² = [tex]\frac{7}{2}[/tex]
Step-by-step explanation:
[tex]2x^{2}[/tex] + 12x - 7x - 42 = 0
2x^{2} (x + 6) - 7 (x + 6) = 0
(x + 6) x (2x - 7) = 0
x + 6 = 0
2x - 7 = 0
x = - 6
x = [tex]\frac{7}{2}[/tex]
x = - 6, x² = [tex]\frac{7}{2}[/tex]
A number m is no less than –1 or less than or equal to −5.
Answer:
-1 < m ≤ - 5
Step-by-step explanation:
Your expression includes: m, -1, -5, >, ≤
m is the value being compared so it will be in the middle.
# sign m sign #
m is no less than -1: no less than means it is greater than -1, but does not include -1. Therefore, our sign is >
m > -1
m is less than or equal to -5. This means we use ≤ because it can equal -5.
m ≤ -5
Now combine the two expressions
m > -1 – This can also be written as -1 < m.
m ≤ -5
-1 < m ≤ - 5
4) The path of a satellite orbiting the earth causes it to pass directly over two
tracking stations A and B, which are 60 km apart. When the satellite is on one side of
the two stations, the angles of elevation at A and B are measured to be 86.4 ° and
85 °, respectively.
Find how far the satellite is from station A and how high the satellite is above the
ground. Round your answers to 2 decimal places.
Answers:
Satellite is approximately 2446.43 km from station A.Satellite is approximately 2441.61 km above the ground.=========================================================
Explanation:
I'm assuming tracking stations A and B are at the same elevation and are on flat ground. In reality, this is likely not the case; however, for the sake of simplicity, we'll assume this is the case.
The diagram is shown below. Points A and B describe the two stations, while point C is the satellite's location. Point D is on the ground directly below the satellite. We have these lengths
AB = 60 kmAD = xCD = hFocusing on triangle ACD, we can apply the tangent rule to isolate h.
tan(angle) = opposite/adjacent
tan(A) = CD/AD
tan(86.4) = h/x
x*tan(86.4) = h
h = x*tan(86.4)
We'll use this later in the substitution below.
--------------------
Now move onto triangle BCD. For the reference angle B = 85, we can use the tangent rule to say
tan(angle) = opposite/adjacent
tan(B) = CD/DB
tan(B) = CD/(DA+AB)
tan(85) = h/(x+60)
tan(85)*(x+60) = h
tan(85)*(x+60) = x*tan(86.4) ............. apply substitution; isolate x
x*tan(85)+60*tan(85) = x*tan(86.4)
60*tan(85) = x*tan(86.4)-x*tan(85)
60*tan(85) = x*(tan(86.4)-tan(85))
x*(tan(86.4)-tan(85)) = 60*tan(85)
x = 60*tan(85)/(tan(86.4)-tan(85))
x = 153.612786190499
--------------------
We'll use this approximate x value to find h
h = x*tan(86.4)
h = 153.612786190499*tan(86.4)
h = 2441.60531869599
h = 2441.61 km is how high the satellite is above the ground.
Return to triangle ACD. We'll use the cosine rule to determine the length of the hypotenuse AC
cos(angle) = adjacent/hypotenuse
cos(A) = AD/AC
cos(86.4) = x/AC
cos(86.4) = 153.612786190499/AC
AC*cos(86.4) = 153.612786190499
AC = 153.612786190499/cos(86.4)
AC = 2446.43279498247
AC = 2446.43 km is the distance from the satellite to station A.
The hypotenuse of a right triangle is 78 feet. One of the legs of the triangle is 30

The perimeter of a rectangular backyard is 146 feet. It is 40 feet long. How wide is it?
9514 1404 393
Answer:
33 ft
Step-by-step explanation:
The perimeter formula for a rectangle is ...
P = 2(L +W)
Filling in the given numbers, we have ...
146 = 2(40 +W)
73 = 40 +W . . . . . . . divide by 2
33 = W . . . . . . . . . . . subtract 40

CAUSE THIS WORK IS HARD AND IM IN THE 3RD GRADE
Answer:
400
Step-by-step explanation:
so the question is 20 times 20. This problem means you are doing 20, 20 times. Since you are in 3rd grade I will use the counting meathod. So to do this you need to count starting at 20 by 20 20 times.
20 40 60 80 100 120 140 160 180 200 220 240 260 280 300 320 340 360 380 400.
As you can see the answer is 400. I started at 20 and I consistently counted by 20. Also I did it 20 times. I did this because the problem says to do 20, twenty times.

» Seven more than a number, 2, is at most 20.
1) Which inequality represents this statement?
7 – < 20
7 + x < 20
7 - 2 > 20
7 + x > 20
Answer:
i believe its 7 + x < 20
Step-by-step explanation:
The inequality function that represent the given statement should be 7 + x < 20. The second option is correct.
What is the inequality function?It is the relationship type that shows the relationship with the graph.
Since the statement like
Seven more than a number, 2, is at most 20.

A
22 ft²
B
39 ft²
C
44 ft²
D
154 ft²
The family needs to cover 39ft² area of grass.
What is Area of Circle?The area of a circle is the amount of space enclosed within the boundary of a circle. The region within the boundary of the circle is the area occupied by the circle.
Here, Diameter = 7 ft.
Radius = 7/2 ft. = 3.5 ft.
The Area of Circle = πr²
A = 3.14 X (3.5)²
A = 3.14 X 3.5 X 3.5
A = 38.465 ft² ≈ 39 ft²
Thus, the family needs to cover 39ft² area of grass.
