Answer:
$y=(7/2)x+20$
Step-by-step explanation:
SInce the gradient of the first line is $-2/7$ then the gradien of the perpendicular line is $7/2$.
Therefore by the point slope formula the line that we are looking for is
$y-6=(7/2)(x+4)$
$y=(7/2)x + 20$
The Martino family bought 5 movie
tickets and 3 tubs of popcorn for $39.50.

Aruba has the lowest population
It would be 'Aruba has the least population'
Bolivia has an exponet of 7, 7 zeros while Aruba has 5
The Philippines has a population that is a multiple of Aruba, as long as it's not 1 or less it's going to be greater then Aruba
Therefore since both would have more, your true statement would be the first one

B. 2³(3 x 5² + 2²)
C. 2³ (3 x 5² + 2⁵)
D. 2⁴(3 x 5⁵ + 2¹⁶)
Plz help meee!
Answer:
B. 2³(3 x 5² + 2²)
Step-by-step explanation:
2³(3 x 5² + 2²)
Step 1. Simplify the exponents
8(3 x 25 + 4)
Step 2. Multiply 3 and 25
8(75 + 4)
Step 3. Add 75 and 4
8(79)
Step 4. Multiply
632
Answer:
Option B. 2³(3 x 5² + 2²) is correct
Step-by-step explanation:
2³(3 x 5² + 2²)
First of all multiply the exponents
8×(3×25+4)
Then do the multiplication of 3 and 25
8×(75+4)
Now add the following numbers in the bracket
8×(79)
And the last multiply the following numbers
8×79
632
[Hence, the expression 2³(3 x 5² + 2²) is equal to 632. ]
How many ounces of a 15% alcohol solution must be mixed with 4 ounces of a 20% alcohol solution to make a 17% alcohol solution?
Answer:
6 ounces
Step-by-step explanation:
Let x = the number of ounces of the 15% alcohol solution needed to be mixed with the 4 ounces of 20% alcohol solution to obtain the 17% alcohol solution.
After converting the percentages to their decimal equivalents, set up the necessary equation as follows:
0.15x+0.20(4) = (x+4)(0.17) Simplify and solve for x.
0.15x+0.8 = 0.17x+0.68 Subtract 0.15x from both sides.
0.8 = 0.02x+0.68 Now subtract 0.68 from both sides.
0.12 = 0.02x Finally, divide both sides by 0.02
x = 6
You need to mix 6 ounces of 15% alcohol solution with 4 ounces of 20% alcohol solution to obtain 10 (x+4)ounces of 17% alcohol solution.
Answer:
Therefore 2 ounces of 11% alcohol solution must be mixed with 4 ounces of 20%alcohol to make a 17%alcohol solution
Step-by-step explanation:
Let x ounces of 11% alcohol must be mixed with the 2 ounces of 20% alcohol.
The amount of alcohol in 4 ounces solution is= ounces
= 0.8 ounces
The amount of alcohol in x ounces solution is= ounces
= 0.11 x ounces
Total amount of alcohol is = (4+x) ounces
According to the problem,
Therefore 2 ounces of 11% alcohol solution must be mixed with 4 ounces of 20%alcohol to make a 17%alcohol solution

what are the coordinates of point G ,which divides DE un the ratio 2:3?
Answer:
(5, 7.8)
Step-by-step explanation:
There are several ways to solve this problem, but all of them involve similar triangles and ratios.
See the attached image.
The horizontal distance between points D and E is 11 - 1 = 10. If a segment 10 units long is divided in the ratio 2:3 (as shown by the two smaller segments of length a and b), then
[tex]\frac{a}{b}=\frac{2}{3}\\\frac{a}{a+b}=\frac{2}{2+3}\\\frac{a}{10}=\frac{2}{5}[/tex]
"Cross-multiply" to get
5a = 20
a = 4
To get the x-coordinate of point G, add 4 to 1, the x-coordinate of D.
The x-coordinate of G is 1 + 4 = 5.
The same idea can be used on the second coordinate of G.
The vertical distance from D to E is 15 - 3 = 12.
[tex]\frac{a}{b}=\frac{2}{3}\\\frac{a}{a+b}=\frac{2}{2+3}\\\frac{a}{12}=\frac{2}{5}[/tex]
5a = 24
a = 24/5 = 4.8
The y=coordinate of G is 3 + 4.8 = 7.8
Given AB has a midpoint M where At -2, 8) and M(3,-1), find the coordinates of B
Answer:
B is (8,-10) because A to M goes down 9 units and to the right 5 units

Hope This Helps YouRound the number 2.2 nearest whole number will be 2. Then the correct option is C.
What is the rounding of a number?The action of forming anything into a circle. Mathematics. the act of substituting a number with one that is roughly equivalent in value but has fewer digits: To the closest dollar, rounding $27.68 results in $28. a comparable procedure that identifies one of several rules.
The decimal number is given below.
⇒ 6.4 − 4.2
⇒ 2.2
Round the number 2.2 to the nearest whole number.
If the decimal number is more than 0.5, then the ones place after the decimal will be increased by one.
In the decimal number is 2, then the ones place number 2 remains the same as 2.
Round the number 2.2 nearest whole number will be 2. Then the correct option is C.

The number line is attached in the solution.
What is number line?In math, a number line is a horizontal straight line with numbers placed at equal distances from each other along that line.
A number line is a pictorial representation of numbers on a straight line. It's a reference for comparing and ordering numbers.
Given is an expression, -4-(-1), we need to plot its solution on the number line,
So,
-4-(-1)
Opening the brackets,
= -4+1 [∵ (-) × (-) = +]
= -3
Plotting -3 in the number line, it will be put 3 units left from zero in the number line,
We put negatives number on the left side and the positive numbers on the right side of zero, in the number line,
For example, we are asked to put 7 in the number line, we will count 7 units to the right of zero in the number line, and suppose if we are asked to plot -6, then we will count 6 units to the left of zero in the number line.
The number line is extended from -∞ to +∞
