Translate the phrase into algebraic expression seven more than twice Jose’s height using the variable J to represent Jose height what would be the algebraic expression
Answer:
2j+7
Step-by-step explanation:
Phrase Into Algebraic Expression
If a problem is correctly phrased, it should be easily translated into algebraic language by following simple and concrete rules.
We have the phrase:
7 more than twice Jose's height.
Usually, we first deal with products and divisions before sums and subtractions because of the natural order of mathematic operations.
In the given phrase, the '7 more' part is left to the end and we start with the 'twice' part because it's a product.
Since we are using the variable j for Jose's height, then twice Jose's height is 2j.
Now we finish the expression by adding 7: 2j+7
Thus, the translation to algebraic expression is: 2j+7
My number has ones, tenths and hundredths. Rounding to the nearest whole number, you get 4. Rounding it to the nearest tenth, you get 3.5. The number of the hundredths is greater than 3. What number am I?
Answer:
3.54
Step-by-step explanation:
Well, we know it has to be 3.5 as our ones, and tenths place, (Thats what I did), and we know it can't be less than 3 for our hundredths place
If we do 0.05, or more as our hundredths place, than we won't be rounding right for the tenths place, so it has to be 3.54
The number in question that shows the decimal digits is; 3.54
We are told that the number has;
- Ones
- tenths
- hundredths
Thus means that the number is in 2 decimal places.
If we approximate to the nearest tenth and get 3.5, it means that the last number on the right of the decimal which is the hundredths is less than 5. It also means that the first number to the right of the decimal will remain as 5.
We are now told that this hundredths number is greater than 3. Thus, the hundredths number is 4.
If the approximation to the nearest whole number gives 4, it means that the number before the decimal will be 3.
Thus,in conclusion, the number is 3.54.

5.Monty made a scale drawing of his room on grid paper, as shown below.
If each square on the grid paper represents a side length of 2 feet, what is the length, in feet,
of the longest wall in the room
Answer: 16 feet
Step-by-step explanation:
Looking at the drawing, the longest wall in the room is the horizontal length of the scale drawing.
Looking at the longest wall, the number of squares with a side length on the line of the wall are 8 in number.
If each square represents a side length of 2 feet, the length of the wall will be;
= 2 * 8
= 16 feet

Answer:
x= 3√3y= 3Step-by-step explanation:
1) Add 30+90 to get 120 and subtract 180-120= 60 as your third angle.
2) Take sin60= x/6 to get x= 3√3
3) Take sin30= y/6 to get y= 3
Here's a tip to verify this answer.
Use Pythagorean Theorem to do:
Square root of (3√3)^2 + 3^2 which equals 6 as your hypotenuse!
Solve the equation:
y^2=-11y
Answer:
-5.5
Step-by-step explanation:
divide both sides by y which deleted y on the right side. then the left side turns into y instead of y squared. then you have y equals -5.5
the ratio of horses to chickens on a farm is 9:4. If there are a total of 169 animals, how many chickens are on the farm?
Answer:
52 chickensStep-by-step explanation:
Step one:'
given
we are told that the total number of animals is 169
the ratio of horses to chickens= 9:4
total ratio= 13
Required:
number of chickens
Applying part to all principle, let the number of chickens be x
4/13=x/169
cross multiply
4*169=13*x
divide both sides by 13
x=4*169/13
x=676/13
x=52
There are 52 chickens
Solve for x helppp(10 points)
Answer:
x = n - m
Step-by-step explanation:
To solve for x we have to isolate it.
[tex]x^{2} \\[/tex] + [tex]m^{2}[/tex] = [tex]n^{2}[/tex]
First, let's subtract [tex]m^{2}[/tex] from both sides of the equation:
[tex]x^{2} \\[/tex] + [tex]m^{2}[/tex] - [tex]m^{2}[/tex] = [tex]n^{2}[/tex] - [tex]m^{2}[/tex]
Now the equation looks like this: [tex]x^{2} \\[/tex] = [tex]n^{2}[/tex] - [tex]m^{2}[/tex]
Now we have apply a square root to both sides to remove the exponent from the x: [tex]\sqrt{x^2}[/tex] = [tex]\sqrt{n^2 - m^2}[/tex]
The square root and the exponents cancel out on both sides and you're left with: x = n - m
To solve for x the equation is: x = n - m

A kite is flying 99 ft off the ground, and it's string is pulled taut. The angle of elevation of the kite is 41°. Find the length of the string. Round your answer to the nearest tenth
Answer:
150.90 feet
Step-by-step explanation:
It is given that,
A kite is flying 99 ft off the ground
The angle of elevation is 41°.
We need to find the length of the string. Let it is H.
Here, 99 ft is the perpendicular of a right angled triangle. We need to find hypotenuse of the triangle. Using trigonometry we can find it as follows :
[tex]\sin\theta=\dfrac{P}{H}\\\\H=\dfrac{P}{\sin\theta}\\\\H=\dfrac{99}{\sin(41)}\\\\H=150.90\ \text{feet}[/tex]
So, the length of the string is 150.90 feet.

Step-by-step explanation:
A photo 5 inches wide and 8 inches long is enlarged.
How long is the new photo if it is (1)10 inches; (2)15 inches; (3)8 inches wide?
The new photo is_long if it is 10 in wide.
The new photo is_long if it is 15 in wide.
The new photo is_long if it is 8 in wide.
Answer:
1.16 in
2.24 in
3.12.8 in
Step-by-step explanation:
We are given that
Width of photo=5 in
Length of photo=8 in
We have to find the length of new photo in each case.
1. Let x represent the width and y represents the length of photo.
When width increase then length of photo is also increases then it is direct proportion.
Substitute the values then we get
Hence, the length of photo=16 in
2.Width=x=15 in
Again using the formula
Hence, the length of new photo=24 in
3. Width =x=8 in
Substitute the values in the given formula
Hence, the length of new photo=12.8 in
Answer:
1.16 in
2.24 in

3) How many counting numbers less than 50 are multiples of both 3 and 5?
Answer: 3 numbers
Step-by-step explanation:
For this questions to be solved, we need to write the multiples of both 3 abd 5 that are less than 50. This will be:
Multiples of 3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48
Multiples of 5 = 5, 10, 15, 20, 25, 30, 35, 40, 45.
Common multiples = 15, 30 and 45
Therefore, the numbers that is less than 50 that are multiples of both 3 and 5 are 3 numbers

The Point (0,0) is a solution to which of these inequalities?
Answer:
(0, 0) s the solution of y-4 < 3x-1 as it satisfies the inequality.
Hence, option C is true.
Step-by-step explanation:
Given the point (0, 0)
a)
Putting the point (0, 0) the inequality
y+4 < 3x-1
0+4 < 3(0)-1
4 < -1
This is false as -1 can not be greater than 4
b)
y-1 < 3x-4
Putting the point (0, 0) the inequality
0-1 < 3(0)-4
-1 < -4
This is false as -1 can not be lesser than -4
c)
y-4 < 3x-1
Putting the point (0, 0) the inequality
0-4 < 3(0)-1
-4 < -1
This is true as -4 is lesser than -1
d)
y+4 < 3x+1
Putting the point (0, 0) the inequality
0+4 < 3(0)+1
4 < 1
This is false as 4 can not be lesser than 1
Therefore, (0, 0) s the solution of y-4 < 3x-1 as it satisfies the inequality.
Hence, option C is true.
