Answer:
Coordinates of M = \(\left ( -2,4 \right )\)
Step-by-step explanation:
Given: AM:MB = 1:4, A has coordinates (-4, 3) and B has coordinates (6, 8)
To find: coordinates of M
Solution:
According to section formula, if M(x, y) divides line joining points \(A(x_1,y_1)\,,\,B(x_2,y_2)\) in ratio \(m:n\) then coordinates of point M are \(\left ( \frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n} \right )\)
Put \(A(x_1,y_1)=(-4,3)\,,\,B(x_2,y_2)=(6,8)\,,\,m:n=1:4\)
Therefore,
\((x,y)=\left ( \frac{6-16}{1+4},\frac{8+12}{1+4} \right )=\left ( -2,4 \right )\)

What is 15 + (-3) please help me
Answer:
12
Step-by-step explanation:
15 + (-3) = 12
you could also write it as 15 - 3 = 12
Answer: 12
Explanation:
15 is in +
-3 is in -
So, - and + = -
Write the Equation
15 - (-3)
(Do normal subtraction)
= 12 (which sign do we use?)
15 > -3
greater number sigh is + so,
+12 or 12 is the answer
A pole that is 3.2m tall casts a shadow that is 1.14m long. At the same time, a nearby tower casts a shadow that is 39.75m long. How tall is the tower? Round your answer to the nearest meter.
Answer:
112 meters--------------------------------
The heights and shadows are proportional since they form similar triangles.
Set equal proportions and solve for the missing length:
H/h = S/s, where H and h represent heights, S and s - shadows.H/3.2 = 39.75/1.14H = 3.2*39.75/1.14H = 112 (rounded)Answer:
112 meters
Step-by-step explanation:
3.2/1.14 = x/39.75
3.2/1.14 = 2.81
2.81 * 39.75 = 111.57 = 112

Avery noticed that 9/10 (fraction) of the apples in a basket are red. There are 45 red apples in the basket.
(a) Represent the situation with an equation. Use a for the variable.
(b) Solve the equation in Part (a). Show your work.
(c) What does the solution of the equation represent in the situation?
Answer:
a.) (9/10)a = 45
b.) a = 50
We can solve this if we multiply both sides by (10/9), it gives;
(10/9)*(9/10)*a = (10/9)*45
a = (10/9)*45 = 50
c.) a = Total number of apples

Josiah’s work:
StartFraction 10 over 20 EndFraction = StartFraction x over 1,500 EndFraction. StartFraction 10 times 30 over 20 times 30 EndFraction = StartFraction x over 1,500 EndFraction. 300 = x.
He should have found the average of the number of rock songs by averaging 4 and 6 to get 5.
He did not multiply the numerator and denominator by the correct number to equal 1,500.
His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion.
He can only solve the proportion by multiplying the numerator and denominator by a common multiple.
He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500.

(jk−1)÷j when j=−4 and k=−0.7
Answer: -0.45
Step-by-step explanation:
Plug in the variables
(-4 × -0.7 - 1) ÷ -4
Simplify
(2.8 - 1) ÷ -4
1.8 ÷ -4
-0.45
When j = 4 and k = 0.9, the answer in decimal notation to the above equation (jk1)j is 0.65.
What is meant by decimal?An accepted approach for notating both integers and non-integers is the decimal number system. It is a non-integer number extension of the Hindu-Arabic number system. The term "decimal system" is frequently used to refer to the system of representing numbers.
Start by dividing decimals by ten before multiplying them.. Next, determine how many decimal places there are for each factor. Put the same amount of digits after the product's decimal points.
There are three varieties of decimal numbers:
non-repeating
recurring
decimal fractions
Given:
j = 4 and k = 0.9
(jk − 1) ÷ j
equating the values in the given formula
(4 × 0.9-1) ÷ 4
= (3.6 - 1) ÷ 4
= 2.6 ÷ 4
= 0.65
Therefore When j = 4 and k = 0.9, the answer in decimal notation to the above equation (jk1)j is 0.65.

Answer:

Step-by-step explanation:
You divide 3 3/4 by 1 1/2
First turn the mixed numbers into improper fractions.
Multiply the whole number by the denominator then add the numerator. Keep the denominator the same.
3 3/4:
3 x 4 = 12
12+3
= 15/4
1 1/2 :
1 x 2= 2
2+1
= 3/2
now you're dividing 15/4 by 3/2
My teacher always taught me KFC:
Keep, change flip
Keep:
Keep the first fraction don't change it. 15/4 stays the same.
Change:
Change the division sign to multiplication.
Flip:
Flip the last fraction to its reciprocal.
In this case instead of it being 3/2, it will be 2/3
Next
Multiply straight across
15/4 x 2/3
15 x 2 = 30
4 x 3 = 12

Simplified would be 5/2 as an improper fraction

Point A, located at (5, -4) is reflected in the y-axis, resulting in the location of point A'. Which of the following statements is true?
Point A' is located at (-5,-4)
Point A' is located at (-5,4)
Point A is located at (4,5)
Point A' is located at (-4,5)
The correct answer is Point A' is located at (-5, -4).
When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).
