Answer:
[tex]49v^{2} +42v+9[/tex]
Step-by-step explanation:
First, let me say, I'm not sure what exactly the equation is because it's worded weirdly, but I'm assuming it's [tex](7v+3)^{2}[/tex].
(7v+3)(7v+3) [[tex]7v+3^{2}[/tex] is the same as (7v+3)(7v+3).]
[tex]49v^{2} +42v+9[/tex] [When you multiply them, this is the product.]
This is as far as you can simplify without knowing the value of v as far as I know.
What is the distance between (8, -3)and (4,−7)?
Answer:
+4sqrt(2)
Step-by-step explanation:
Note that the horizontal distance is 8 - 4, or 4 (which is the "run") and that the vertical distance is -3 - (-7), or 4 (which is the "rise"). Applying the Pythagorean Theorem, we get:
distance = length of hypotenuse = +sqrt(4^2 + 4^2) = +4sqrt(2)
Determine the measure of ∠Y. images attached
Answer:
The answer is option CStep-by-step explanation:
Since it's a right angled triangle we can use trigonometric ratios to find the value of ∠Y
To find the value of ∠Y we use tan
We have
[tex] \tan(∠Y) = \frac{25}{20} \\ \tan(∠Y) = \frac{5}{4} \\ ∠Y = { \tan^{ - 1} } \frac{5}{4} \\ ∠Y = 51.34019...[/tex]
We have the final answer as
51.34°Hope this helps you
Answer:
C
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanY = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{XZ}{XY}[/tex] = [tex]\frac{25}{20}[/tex] , thus
∠ Y = [tex]tan^{-1}[/tex] ( [tex]\frac{25}{20}[/tex] ) ≈ 51.34° → C

Gigi makes a scale drawing of a patio. The drawing below shows the two scales she used to plan two patios of different sizes. Scale 1: 1 centimeter = 5 feet. Scale 2: 1 centimeter = 8 feet. A rectangle with length 7 centimeters and width 5 centimeters. Which shows the correct dimensions of the rectangle in both scales? Scale 1: 40 ft by 56 ft; Scale 2: 35 ft by 40 ft Scale 1: 56 ft by 25 ft; Scale 2: 35 ft by 40 ft Scale 1: 35 ft by 25 ft; Scale 2: 56 ft by 40 ft Scale 1: 56 ft by 40 ft; Scale 2: 35 ft by 25 ft
Answer:
Scale 1: 35ft by 25ft
Scale 2: 56ft by 40ft
Step-by-step explanation:
Given
Rectangle: 7cm by 5cm
Scale 1: 1cm = 5ft
Scale 2: 1cm = 8ft
Required
Determine the scale measurement
For Scale 1:
Actual Measurement
[tex]Length = 7cm[/tex]
[tex]Width = 5cm[/tex]
Scale 1: 1cm = 5ft
To calculate the scale measurement, we have to multiply the actual measurements by 5:
This gives:
[tex]Length = 7 * 5ft[/tex]
[tex]Length = 35ft[/tex]
[tex]Width = 5 * 5ft[/tex]
[tex]Width = 25ft[/tex]
So, the new measurement is 35ft by 25ft
For Scale 2:
Actual Measurement
[tex]Length = 7cm\\Width = 5cm[/tex]
Scale 2: 1cm = 8ft
To calculate the scale measurement, we have to multiply the actual measurements by 8:
Scale Measurement:
[tex]Length = 7 * 8ft[/tex]
[tex]Length = 56ft[/tex]
[tex]Width = 5 * 8ft[/tex]
[tex]Width = 40ft[/tex]
So, the new measurement is 56ft by 40ft
Answer:
c). Scale 1: 35 ft by 25 ft; Scale 2: 56 ft by 40 ft

Step-by-step explanation:
114° thats what i got when i calculated
what is the value of x in the equation 3(x-2)+4x=10(x+1)
Answer:
-16/3 =x
Step-by-step explanation:
3(x-2)+4x=10(x+1)
Distribute
3x -6 +4x = 10x +10
Combine like terms
7x -6 = 10x+10
Subtract 7x from each side
7x-6-7x = 10x-7x +10
-6 = 3x+10
Subtract 10 from each side
-6-10 = 3x+10-10
-16 = 3x
Divide by 3
-16/3 = 3x/3
-16/3 =x
Find the measure of x that would make m∥n.
Answer:
to get the value of xtake 4x + 2x + 36 degrees is equals to 180 degrees this is because 4X and 2x + 36 degrees are angles on a straight line because 4X corresponds to the angle on top of 2x + 36 degrees so back to the equation we collect the like terms it will be 4 x + 2 x is equals to 180 degrees minus 36 degrees 6 x is equals to 144 x is equals to 24 degrees

What is -9 over 22 divided by -3 over 4 in fractions?
Answer: 6/11
Step-by-step explanation:
Answer:
3/4
Step-by-step explanation:
You'll need to make compatible numbers first. Turn 22 to 44 and 4 to 11. Then change -9 to -18 and -3 to -6. -9 times -3 equals 3. and 44 divided by 11 is 4. So your answer is 3/4

A car travels at 20 m/s for 15 seconds before it comes to rest by decelerating at 2.5 m/s2
Find the total distance travelled.
Answer:
80 m
Step-by-step explanation:
From the question;
Initial velocity, u, = 20m/s
Time = 15 s
deceleration= -2.5 m/s² ------negative acceleration
The formula to apply is;
v²=u²+2as
where v is the final velocity = 0m/s and s is the total distance travelled.
Applying the formula as;
v²=u²+2as
0²=20²+ 2*-2.5*s
0=400+ -5s
0=400-5s
5s= 400
s= 400/5 = 80
s= 80 m
The total distance travelled is 80 m.

The mean test score of 28 students is 72.
A student joins the class and the mean becomes 71.
Find the test score of the student who joined the class.
Test score =
Answer:
test score of new student = 43
Step-by-step explanation:
28 x 72 = 2016 (total points class scored)
29 x 71 = 2059 (total points class scored after student joined)
2059 - 2016 = 43
The test score of the student who joined the class is 43.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The mean test score of 28 students is 72.
A student joins the class and the mean becomes 71.
We have to find the test score of the student who joined the class.
28 x 72 = 2016
29 x 71 = 2059 (total points class scored after student joined)
The difference between 2016 and 2059 is the test score of new student.
2059 - 2016 = 43
Hence, the test score of the student who joined the class is 43.

To win a contest, the number of beans in a jar has to be guessed within 20 of the actual number. If the number of beans in the jar is 645, which equation can be used to find the minimum and maximum number of beans that will win the contest, and what is the maximum guess that could win?
|x – 645| = 20; maximum guess: 635 beans
|x – 645| = 20; maximum guess: 665 beans
|x – 20| = 645; maximum guess: 635 beans
|x – 20| = 645; maximum guess: 665 beans
Answer:
B
Step-by-step explanation:
Just took the test on edge 2020
The maximum guess that could win is,
⇒ |x - 645| = 20; the maximum guess is 665.
Therefore, Option b is correct.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Since, We have given the information that the jar has to be guessed within 20
So, the total has to be equal to 20.
Hence, the equation which is the required equation to calculate the minimum and maximum number of beans that will win the contest is,
|x - 645| = 20
When we will remove the modulus we will get two values + and -
So, x = 20 + 645 = 665
And x = 20 - 645 = -625
Hence, the maximum guess is 665.
Therefore, Option b is correct.
