Answer:
BC = 10.9 mm
Step-by-step explanation:
The computation of the BC is given below:
Here we applied the pythagorus theorem
AB = 10.8 mm
AC = 1.6mm
BC = ?
Now as we know that
AB^2 + AC^2 = BC^2
10.8mm^2 + 1.6mm^2 = BC^2
116.64mm^2 + 2.56mm^2 = BC^2
BC = 10.9 mm

Answer:
[tex]a = 2[/tex] and [tex]b = 4[/tex]
Step-by-step explanation:
Given
The expression is:
[tex]\frac{x^2 + ax - 4}{x + 2} + \frac{x + b}{x + 2} = x + 1[/tex] --- missing from the question
Required
Find a and b
Take LCM
[tex]\frac{x^2 + ax - 4+x + b}{x + 2} = x + 1[/tex]
Cross Multiply
[tex]x^2 + ax - 4+x + b = (x+2)*(x + 1)[/tex]
Open brackets
[tex]x^2 + ax - 4+x + b = x^2+2x + x + 2[/tex]
[tex]x^2 + ax - 4+x + b = x^2+3x + 2[/tex]
Collect Like Terms
[tex]x^2 + ax +x + b- 4 = x^2+3x + 2[/tex]
[tex]x^2 + (a +1)x + b- 4 = x^2+3x + 2[/tex]
By comparing the coefficients:
[tex]a + 1 = 3[/tex]
[tex]a = 3 - 1[/tex]
[tex]a = 2[/tex]
[tex]b - 4 = 2[/tex]
[tex]b = 4[/tex]
Hence,
[tex]a = 2[/tex] and [tex]b = 4[/tex]

Label ABC with the following information.
AB = 35
AC = 62
Find m/c.
Answer:
m<C = 34.4 °
Step-by-step explanation:
From the question given above, the following data were obtained:
Opposite = AB = 35
Hypothenus = AC = 62
Angle C =?
The value of m<C can be obtained by using sine ratio as illustrated below:
Sine C = Opposite /Hypothenus
Sine C = 35 / 62
Sine C = 0.5645
Take the inverse of sine
C = Sine¯¹ 0.5645
C = 34.4 °
Thus,
m<C = 34.4 °

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 11 feet cubed.
A sphere with height h and radius r. A cylinder with height h and radius r.
Which equation gives the volume of the sphere?
V = four-thirds (11) pi
V = two-thirds (11) pi
V = four-thirds (11)
V = two-thirds (11)
9514 1404 393
Answer:
V = (2/3)(11)
Step-by-step explanation:
The given cylinder has a height of 2r, so its volume is ...
V = πr²(2r) = 2πr³
The volume of a sphere is given by ...
V = 4/3πr³
Then the ratio of the volume of the sphere to the volume of the cylinder is ...
(4/3πr³)/(2πr³) = (4/3)/2 = 2/3
So, the volume of the sphere is 2/3 times the volume of the cylinder:
V = (2/3)(11)

GEOMETRY STUFF PLEASE ANDWER DUE IN 20 MINUTES
Answer:
Statement 2: m∠ ELD = (2x)°
Reason 4: Sum of angles on a straight line is equal to 180°
Statement 6: 2x = 56
Step-by-step explanation:
Since the first step talks about we being given m∠ ELG = 124°, the next thing we are given in the question is that; m∠ ELD = (2x)°
In statement 4,it is written that;
m∠ ELD + m∠ ELG = 180°
The reason behind this is that;
Sum of angles on a straight line is equal to 180°.
For reason 6, we are told it is a subtraction property.
Now the preceding statement gave us;
2x + 124 = 180
Which means that for subtraction property here, we will have;
2x = 180 - 124
2x = 56
A 50 centimeter piece of wire is bent into a circle. What is the area of this circle?
Answer:
198.95 cm²
Step-by-step explanation:
Circumference = 50cm
C = πD
D = C/π
r = D/2
r = 50/π/2
r= 7.957747…..cm
Area = π r²
A = π x 7.957747….²
A = 198.95 cm² (2dp)

In ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°. Find the length of f, to the nearest 10th of an inch.
In ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°. Find the length of f, to the nearest 10th of an inch.
=10.7
The length of f from the given triangle FGH is 10.7 inches.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² − 2bc·cosA.
Given that, in ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°.
Here, f² = 7.6² + 3.2² − 2×7.6×3.2×cos160°
f² = 57.76+10.24-48.64×(- 0.9396)
f² = 68+45.70
f² = 113.7
f = √113.7
f = 10.7 inches
Therefore, the length of f is 10.7 inches.

Step-by-step explanation:
The distance from Charles's house to his school is 3 miles. His father gave him a ride for 1,760 yards, and he walked the rest of the way. The distance that Charles walked is miles or yards. (Hint: 1 mile = 1,760 yards.)
Answer:
2 miles or 3520 yards
Step-by-step explanation:
The distance from Charles's house to his school is 3 miles. His father gave him a ride for 1,760 yards, and he walked the rest of the way. The distance that Charles walked is miles or yards. (Hint: 1 mile = 1,760 yards.)
From the Question, we know that
1 mile = 1,760 yards..
His father gave him a ride for 1,760 yards,
Hence, the number of miles Charle's father drove him was 1 mile
The distance that Charles walked in miles is calculated as:
3 miles - 1 mile
= 2 miles
Converting to yards
1 mile = 1,760 yards..
2 miles = x
Cross Multiply
x = 2 × 1760 yards
= 3520 yards

The equation for the price of a baseball card that was bought for 5 dollars and has appreciated 5% yearly. Find the yearly calue of the card 25 years later
Answer:
The yearly value of the card 25 years later is $16.93.
Step-by-step explanation:
You can use the following formula to find the future value:
FV=PV(1+r)^n
FV= future value
PV= present value= 5
r=rate= 0.05
n=number of periods of time= 25
Now, you can replace the values in the formula:
FV=5(1+0.05)^25
FV=5(1.05)^25
FV=16.93
According to this, the answer is that the yearly value of the card 25 years later is $16.93.

when the arrow is pointing toward the left side that means less than side. When the arrow is pointing towards the right side that means greater than.
Answer:
B, because that symbol means at least so you would go to the negative side which is on the left it has to start from 4 which is correct and this means negative: - The 0 is the origin so from the origin to the left side is negative from the origin to the right side is positive you want to look for negative because it's negative 4.
