Step-by-step explanation:
Solution,
Here
Mean=10
N=6
Efx=7+14+6+p+8+14
=49+p
Now
Mean=Efx/N
or,10=49+p/6 ( Therefore,10 is multiplied to 6)
or,60=49+p
or,p=60-49
p=11
If ΔGFE ~ ΔGHJ, find the value of x.
Answer:
x = 4 and -10.5.
Step-by-step explanation:
Set up the equation:
x+6/12=7.5/2x+1
Then cross multiply, and get your x value.
write the equation of the line with a slope of 1/2 that passes through the point (-6,10)
Answer:
An equation is
[tex]y = \frac{1}{2} x + 13[/tex]
.
Step-by-step explanation:
☆Since since we're given the slope, all we need to do is find the y-intercept.
☆The slope-intercept formula is: y = mx + b.
☆We are going to plug in according to the formula.
[tex]y = mx + b \\ \\ 10 = \frac{1}{2} ( - 6) + b \\ 10 = - 3 + b \\ \frac{ + 3 = + 3 \: \: \: \: \: \: \: \: \: }{13 = b \: \: \: \: \: \: \: \: \: \: \: } [/tex]

The angle of depression from a helicopter to its landing space is 56°. If the helicopter is flying at 1000 ft, find the distance from the helicopter to the landing space
Answer:
[tex]1206.22\ \text{ft}[/tex]
Step-by-step explanation:
The height at which the helicopter is 1000 ft
Angle of depression is [tex]56^{\circ}[/tex]
[tex]\theta=90-56=34^{\circ}[/tex]
We have the relation
[tex]\cos\theta=\dfrac{\text{Adjacent side}}{\text{Hypotenuse}}\\\Rightarrow \cos34^{\circ}=\dfrac{1000}{x}\\\Rightarrow x=\dfrac{1000}{\cos 34^{\circ}}\\\Rightarrow x=1206.22\ \text{ft}[/tex]
The distance of the helicopter to the landing space is [tex]1206.22\ \text{ft}[/tex].

Think about whether these ordered pairs represent a function. Then use the drop-
down menus to complete the statement about the ordered pairs.
(-2,4), (5,6), (0,1), (8, – 7), (9,1)
Answer: All x-coordinates are different, so this relation is a function.
Having the same y value more than once is not a problem for a function.
"This (does not/does) represents a function because different (x values/y values) can have the same (x values/y values)."

Malcolm is feeling bags with rice he starts with a 5 1/4 pound container of rice and shells each bag with 5/8 pound of rice how many bags of rice can Malcolm fill
Answer:
8 2/5 bags of rice
Step-by-step explanation:
The above question is solved as;
5/8 pounds of rice = 1 bag of rice
5 1/4 pounds of rice = x bags of rice
Cross Multiply
5/8 pounds × x bags of rice = 5 1/4 pounds of rice × 1 bag of rice
x bags of rice = 5 1/4 pounds of rice × 1 bag of rice/ 5/8 pounds
x bags of rice = 5 1/4 ÷ 5/8
x bags of rice = 21/4 ÷ 5/8
x bags of rice = 21/4 × 8/5
x bags of rice = 42/5
x bags of rice = 8 2/5 bags of rice
Therefore, malcolm can fill 8 2/5 bags of rice.
Riya wants curtains in her room. These are the lengths of curtains in metres. 1.0 m, 1.25 m, 1.5 m The lengths follow a pattern. Riya wants the next length up from 1.5 m. What length of curtains will Riya buy?
Answer:
1.75
Step-by-step explanation:
Since the curtains are going up in .25. We need to add .25 to 1.5.
1.5 + .25 = 1.75
The length of curtains will Riya buy is 1.75 m.
What is sequence?A sequence is an arrangement of numbers in a specific order. A series, on the other hand, is defined as the sum of the elements in a sequence.
For example, In the sequence 1, 3, 5, 7, 9, …, 1 is the first term, 3 is the second term, 5 is the third term, and so on.
We have length of curtains as
1m, 1.25 m, 1.5 m,...
Now, from above the first term is 1.
Common difference, d= 1.25 - 1 = 0.25
So, the next length of curtain will be
= 1 + (4-1)0.25
= 1 + 0.75
= 1.75 m

Answer:
C
Step-by-step explanation:
a) [tex]\frac{-3}{4}* ( -8) +4 = 6 \\[/tex]
(a) has an answer of 6 which is greater than 1
that means (a) is not the answer

Which property is shown by 9+8=8=9?
1: Distributive Property
2: Commutative Property of Addition
3: Associative Property of Addition
Answer:
A. Commutative Property of Addition
Step-by-step explanation:
Given equation,
9 + 8 = 8 + 9
If a and b are any real numbers,
By the commutative Property of Addition
a + b = b + a
By the identity Property of Addition
a + 0 = a
By the distributive Property,
a(b+c) = ab + ac
By the associative property of addition,
a + (b + c ) = (a + b) + c
Hence, OPTION A is correct.
Answer:
Commutative Property of Addition
Step-by-step explanation:
I assume you mean 9+8=8+9
In that case it is the Commutative Property of Addition.
That means you can switch the numbers around and it will stay the same value.

Answer:
62°
Step-by-step explanation:
The measure of the external angle where the secants meet is half the difference of the arcs they subtend.
∠A = (DE - BC)/2
2×∠A = DE -BC
DE = BC + 2×∠A
DE = 38° +2(12°)
