Answer:
square root of 50 estimated to the nearest integer is, 7.1
Step-by-step explanation:
step 1. the square root of 50 is 7.07106781186548
step 2. reduce is 7.07
step 3. round 7.07 so you only have one digit after the decimal point to get the answer., 7.1
Answer:
7
Step-by-step explanation:
Consider perfect squares either side of 50, that is
49 < 50 < 64, thus
[tex]\sqrt{49}[/tex] < [tex]\sqrt{50}[/tex] < [tex]\sqrt{64}[/tex] , that is
7 < [tex]\sqrt{50}[/tex] < 8
Since 50 is nearer to 49 than it is to 64, then
[tex]\sqrt{50}[/tex] ≈ 7 ( to the nearest integer )

Ashley rolls a die, flips a corner, and then roll the die again. What is the probability that he will roll to our numbers And that the coin will land on heads?
Answer:
1/72
Step-by-step explanation:
Given that Ashley rolls a die, flips a corner, and then roll the die again.
Since he rolls a die two times, the number of total possible outcomes for each roll will be equal to 6
Also, the number of possible outcomes for a coin will be equal to 2
What is the probability that he will roll to our numbers And that the coin will land on heads
The probability will be
1/6 ×1/6 × 1/2 = 1/72

What is the value of x in the equation LaTeX: \frac{3}{2}\left(4x-2\right)-3x=5-\left(x+2\right) 3 2 ( 4 x − 2 ) − 3 x = 5 − ( x + 2 ) ?
Answer:
x = 3/2
Step-by-step explanation:
x = 3/2
Step-by-step explanation:
Given the equation 3/2(4x-2)-3x = 5-(x+2)
Open the parenthesis
3/2(4x) - 3/2(2) -3x = 5-x-2
6x-3-3x = 3-x
3x-3 = 3-x
Collect like terms
3x+x = 3+3
4x = 6
Divide both sides by
4x/4 = 6/4
x = 3/2
Hence the value of x is 3/2
The next model of a sports car will cost 12.9% more than the current model. The current model costs $35,000. How much will the price increase in dollars
Answer:
The price increase in dollars= $4,515
Step-by-step explanation:
Cost of the next model = cost of the current model + 12.9% cost of the current model
Cost of the current model = $35,000
12.9% cost of the current model
= 12.9/100 × $35,000
= 0.129 × $35,000
= $4,515
Cost of the next model = cost of the current model + 12.9% cost of the current model
= $35,000 + $4,515
= $39,515
Cost of the next model = $39,515
The price increase in dollars= next model price - current model price
=$39,515 - $35,000
= $4,515
The price increase in dollars = $4,515

Joe wants to buy a toaster that costs $15 dollars. The sales tax on the toaster is 5%. What is the total cost Joe will pay for the toaster? (Please explain how you solved the problem)
Answer:
$15.75
Step-by-step explanation:
You can do this a couple of ways.
(1) Compute the tax, and add it to the price to find the total.
5% × $15 = 0.05 × $15 = $0.75 . . . . amount of tax
Then the total cost is $15 + $0.75 = $15.75.
__
(2) Add the percentage to 100% and use that to multiply the cost.
total cost = $15 + 5% × $15 = $15×(100% +5%) = $15×1.05
total cost = $15.75
What is LaTeX: m\angle PQRm ∠ P Q R? Line PS with midpoint at Q and ray QR. Angle pqr is 3x-6 and angle rqs is x+2
Answer:
132°Step-by-step explanation:
If line PS has midpoint a Q and ray QR, then line PQS will be a straight line and <PQR + <RQS = 180 (sum of angle on a straight line).
Given
<PQR = 3x-6
<RQS = x+ 2
To get x, we will use the relationship above;
3x-6+x+2 = 180
4x-4 = 180
add 4 to both sides
4x-4+4 = 180+4
4x = 184
x = 184/4
x = 46
Since <PQR = 3x-6, we will substitute the value of x into the formula;
<PQR = 3x-6
<PQR = 3(46)-6
<PQR = 138-6
<PQR = 132°
Hence the size of angle PQR is 132°

A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The members of the choir decided to order from a printing company that charges $3 per shirt, plus a $50 fee for each color to be printed on the shirts.
Answer:
3(75) + 50C
Step-by-step explanation:
Suppose a school needs to make T-shirts for its 75 members and the ordered printing company charges $3er shirt. This implies that the total amount that will be paid for the shirt without being a colored printing will be :
3(75) ----- Let that be equation (1)
If a school choir needs to make T Shirts for its 75 members and the printing company charges $3 per shirt, the total amount paid for shirts without coloured printing will be $3 * 75 = 3(75) ... 1
However, if the ordered printing company charges a $50 fee for each color to be printed on the shirts, therefore, the total number of colors on the shirt will cost $50C --- Let that be equation (2)
here, C represents the total amount of colors in the number of T-shirts
Therefore, the equation showing the relationship between the number of T-shirts ordered and the number of colors can be expressed as the summation of the above two equations:
= 3(75) + 50C
Ronald wants to paint his drawing room wall which measures 8 feet by 9 feet. The cost of the paint is $14 per square foot. How much will it cost Ronald to paint the wall
Answer:
$1036
Step-by-step explanation:
His room is 8 x 9 = 72 feet. The cost of each square foot is $14.
So 72ft x $14 = $1036. So its going to cost him $1036.

7. The island is rich with hot chili peppers. You can collect 1.6 pecks a day. How many liters could you collect in 1 week?
The required liters of hot chili papers collected in a week is 98.56 liters.
What is a unit of measurement?Unit of measurement is defined as every entity having its measures in dimensions, weight, and time. Such as for length we have a meter, for liquid we have liters, and so on.
1 peck = 8.8 liters
1.6 peck = 8.8 × 1.6 liters
1.6 pecks = 14.08 liters
So, in 1-week liter that could be collected is given as,
⇒ 14.08 × 7 [1 week = 7 days]
⇒ 98.56 liters
Thus, the required liters of hot chili papers collected in a week is 98.56 liters.

help me with this, please
Answer:
Correct Answer: Option A
Step-by-step explanation:
cos(x + 25o) = sin 45o
using cos θ = sin(90 - θ)
cos(x + 25o) = cos(90 - 45)
cos(x + 25o) = cos 45
x + 25 = 45
x = 45 - 25
x = 20o

A scientist has two kinds of solutions. The first solution is Solution A, which is an $80\%$ acid solution. The second solution is Solution B, which is a $30\%$ acid solution. (a) Find the amount of Solution A (in mL) that must be added to $500$ mL of Solution B in order to produce a $70\%$ acid solution. (b) Find the amount of Solution A and Solution B (in mL) that can be combined in order to form a $100$ mL solution that is $50\%$ acid. (c) Does there exist a combination of Solution A and Solution B that is $90\%$ acid?
Answer:
Step-by-step explanation:
a ) Let the volume required be v .
v x .8 + 500 x .3 / ( v + 500 ) = .7
.8 v + 150 = .7 v + 350
.1 v = 200
v = 2000 mL
b )
Let the volume of solution A required be v . The volume of solution of B required will be 100 - v
v x .8 + ( 100 - v ) x .3 / 100 = .5
.8 v + 30 - .3 v = 50
.5 v = 20
v = 40 mL
volume of solution B = 60 mL .
c )
It is not possible because 90 % is more than 80 % the concentration of solution A . Any mixture will have concentration less than 80 % .
volume of solution B = 60 mL

Consider the composite function g (f (x)) = x StartRoot 6 EndRoot. If f(x) = 3x2, what is g(x)?
g (x) = StartRoot 2 x EndRoot
g (x) = StartRoot x + 3 EndRoot
g (x) = StartRoot 6 x EndRoot
g (x) = StartRoot 9 minus x EndRoot
Answer:
The answer is A on edge
Step-by-step explanation:
The required function g(x) = √2x
Given that,
The composite function g (f (x))= x √6
f(x) = 3x²
g(x) = To be determine.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
g (f (x))= x √6
g (3x²)= x √6
g (3x²)= √6x²
g (3x²)= √2*3x²
Let
x ⇆ 3x²
g (x)= √2x
Thus, the required function g(x) = √2x.

A plumber charges $55 for a service call plus $40 for each hour he works. If the total bill for a job costs $215, write an equation to represent the situation. 40 + 55 = x + 215 215 = x + 40 + 55 215 = 40 + 55x 215 = 40x + 55
Answer:
The answer is 215=55x+40 or 215=40+55x
Step-by-step explanation:
The reason it is that is because the plumber charges $55 for a service and he adds 40 for each hour he works so that is why this is the answer Remember the total bill cost 215 so that comes as the equation is equal to.
