Answer:
1400 miStep-by-step explanation:
The triangle CHE is right, angle CHE is marked as right angle.
We have:
CD= CH = 3960 miDE = 240 miEH = ?Use Pythagorean theorem to find the value of EH:
CE² = CH² + EH²CE = CD + DE = 3960 + 240 = 4200Substitute known values and solve for EH
4200² = 3960² + EH²EH² = 4200² - 3960²EH² = 1958400EH = √1958400EH = 1399.42 ≈ 1400 mi (rounded)Which expression is equivalent to 4/144a12p3 ? Assume a>0 and >0

find the value of x in the isosceles triangle shown below.
V80
V80
Answer:
Option A. x = 8
Step-by-step explanation:
Please see attached photo.
From the attached photo,
we shall determine the value of y. This can be obtained by using pythagoras theory as illustrated below:
(√80)² = 8² + y²
80 = 64 + y²
Collect like terms
80 – 64 = y²
16 = y²
Take the square root of both side
y = √16
y = 4
Finally, we shall determine the value of x. This can be obtained as follow:
From the attached photo,
x = 2y
but:
y = 4
Therefore,
x = 2y
x = 2 × 4
x = 8

Answer:
answer = 130 degree.
Step-by-step explanation:
I hope is correct.
Answer:
choice 2) angle DOC = 145 degrees
Step-by-step explanation:
angle ABD = 1/2(30 degree arc) = 15 degrees because of the inscribed angle theorem.
angle AOB = 180 - 20 - 15 = 145 degrees
angle DOC = angle AOB because it is a vertical angle to 145 degrees.

can someone solve 3y − 3 = 2y + 6
step by step
Answer:
[tex]y = 9[/tex]
Step-by-step explanation:
1) Add 3 to both sides.
[tex]3y = 2y + 6 + 3[/tex]
2) Simplify 2y + 6 + 3 to 2y + 9.
[tex]3y = 2y + 9[/tex]
3) Subtract 2y from both sides.
[tex]3y - 2y = 9[/tex]
4) Simplify 3y - 2y to y.
[tex]y = 9[/tex]
Therefor, the answer is y = 9.
Answer:
3y-3=2y+6
3y-2y=3+6 (You will group like terms)
therefore,y=9

Step-by-step explanation:
Complementary angles mean that the angles add up to, or equal 90
4x + 6 + 4x - 4 = 90
8x + 2 = 90
8x = 88
x = 11

Kim borrows $3000 for two years. Interest is charged at a rate of 10%. How much interest is paid
5x+ 1/4= 61/4
I’m trying to figure out what x is
I READ IT WRONG AHH
Answer:
3
Step-by-step explanation:
5x + 1/4 = 61/4
-1/4 -1/4
5x = 15
/5 /5
x = 3
Answer:
x=3
Step-by-step explanation:
5x+1/4=61/4
5x=61/4-1/4(61/4-1/4, they have the same denominator so can subtract them with each other)
5x=60/4 (60/4=15)
5x=15
x=15/5
x=3
Tip :to check your answer simply plug in the value and then solve the equation. If both the sides are equal to each other, the answer is most likely correct.
Which expression is equivalent to ¼ m + ¾ m - ⅜ (m+1)?
⅝ m + ⅜
⅝ m - ⅜
⅜ m + ⅝
⅜ m - ⅝
Answer:
5/8m+3/8
Step-by-step explanation:
1/4m+3/4m-3/8(m+1)
1/4m+3/4m-3/8m+3/8
5/8m+3/8
Answer:
5/8m + 3/8
Step-by-step explanation:
1/4m + 3/4m - 3/8 (m + 1)
1/4m + 3/4m - 3/8m + 3/8
5/8m + 3/8

Answer:
10w ≥ 30
Step-by-step explanation:
First, the variable w represents the "sum of a number and 15", so we don't know the missing value. Therefore the first part is 10w. The inequality is ≥ because it represents "at least 30". Your inequality should be 10w ≥ 30

Find the missing term in the geometric sequence. 180,___,5
Answer:
30.
Step-by-step explanation:
first term = a
3r term = ar^2
So here ar^2/ a = r^2
r^2 = 5/180 = 1/36
r = 1/6
So missing term = 180 * 1/6 = 30.

Kenniya wrote 0.2( 4 + 1.4m - 2.1). Below was what she did.
1.) 0.2( 4 + 1.4m - 2.1).
2) 4.2 + 1.6m- 1.9
3) 4.2 - 1.9 + 1.6m
4) 2.3 + 1.6m
Which explains the first mistake Kenniya did?
O Her first mistake was in (2). She added 0.2 to each term instead of multiplying by 0.2
Her first mistake was in (2). She should have only added 0.2 to 4 instead of adding 0.2 to all 3 terms.
O Her first mistake was in (3), the 1.6m should be negative and 1.9 should be positive.
O Her first mistake was in (3), 1.9 should be the coefficient of m instead of 1.6.

In isosceles triangle JKL, JK KL. If the measure of
angle J is 47°, find the measure of angle K.
*Note: Do NOT include the degree in your answer.
Answer:
86
Step-by-step explanation:
Since ∆JKL is an isosceles triangle, it's base angles (<L and <J) would be equal to each other.
<L is opposite to side JK, <J is opposite to side KL.
m<J is given as 47°. Therefore,
m<L = m<J = 47°
m<L = 47°
m<J + m<L + m<K = 180° (sum of triangle)
47° + 47° + m<K = 180° (substitution)
94° + m<K = 180°
m<K = 180° - 94°
m<K = 86°
