Question 1&2 with explanation. Pls fast , no useless and nonsense answers pls
Answer: #1 - A. 210m, #2 - B. 21,39
First, find the width by using the equation 2450 = 2x * x. Multiply the like terms, which results in 2450 = 2x^2. Now, divide both sides by 2, which is 1225 = x^2. The square root of 1225 is 35. Now, to find the perimeter, the equation should be P = 2(70+35). 40 + 35 = 105, and 105*2 = 210. Therefore, the perimeter is A. 210 mNumber 2 is asking what number added by x would result in a perfect square. The first numbers in each of the options for the question so see which one creates a perfect square after it is added to 1500.√ 1500 + 56 = 2 √ 389√ 1500 + 21 = 39√ 1500 + 38 = √ 1538√ 1500 + 39 = 9 √ 19 B. 21, 39 would be the correct answer because it is the only perfect square.Find the value of x and measure of each labeled angle.

7x + 3 = 10x - 5.4
Answer:
2.8
Step-by-step explanation:
Step 1:
7x + 3 = 10x - 5.4 Equation
Step 2:
3 = 3x - 5.4 Subtract 7x from both sides
Step 3:
8.4 = 3x Add 5.4 to both sides
Step 4:
8.4 ÷ 3 Divide
Answer:
x = 2.8
Hope This Helps :)
Answer:
x=2.8
Step-by-step explanation:
7x + 3 = 10x - 5.4
(first, put x's on your left side, and normal numbers on right side, watch out for changing sign in front of the numbers)
7x - 10x = -3 -5.4
(subtract/add up the numbers)
-3x = - 8.4
(divide whole equation with -3 (which is in front of x)
x = 2.8

x = - 2
y = 5
Step-by-step explanation:Hi there !
2x + 9 = y
y = - 4x - 3
equality
2x + 9 = - 4x - 3
2x + 4x = - 9 - 3
6x = - 12
x = - 12 : 6
x = - 2
replace x = - 2
2(-2) + 9 = y
- 4 + 9 = y
y = 5

I think one is 8.7 + 0 = 8.7
Answer: 8.7+0=8.7.
Step-by-step explanation:
Anything that you add with zero is the identity property."An identity is a number that when added, subtracted, multiplied or divided with any number (let's call this number n), allows n to remain the same. The identity will be either 0 or 1, depending on the operation that we are using. In addition and subtraction, the identity is 0." Learn more at "study.com".

It is 7 kilometers from kerrys house to the mall. About what is that distance in miles?
Answer:
[tex]\huge\boxed{\approx 4.4 \ \text{miles}}[/tex]
Step-by-step explanation:
In order to convert kilometers to miles, we can use a formula, assuming [tex]m[/tex] is miles and [tex]k[/tex] is kilometers.
[tex]m = \frac{k}{1.609}[/tex].
Since we know the kilometer reading (7), we can divide this by 1.609 to get our total miles.
[tex]7 \div 1.609 \approx 4.4[/tex]

What is the value of r in the equation 2(2r + 8) = 3r + 16?
Answer:
r=0
Step-by-step explanation:
2(2r+8) = 3r + 16
2×2r + 2×8 = 3r + 16
4r + 16 = 3r + 16
4r + 16 - 3r = 3r + 16 - 3r
r + 16 = 16
r + 16 - 16 = 16 - 16
r = 0

you bought a cell-phone from through a distributor((distributor kept a profit margin of 30%), and a retailer for $150 (retailer kept a profit margin of 20%), and the cell-phone manufacturer wanted to make 10% profit, then the target cost for that cell-phone is:
$64.60
$75.60
$101.60
$105.60
Answer: ___
Answer:
The target cost is [tex] \$ 75.60 [/tex]
Step-by-step explanation:
From the question we are told that
The distributors profit margin is 30%
The retailers price of the phone is $150
The retailers profit margin is 20%
The profit to be made by manufacture is 10%
Generally profit margin is mathematically represented as
[tex]PM = \frac{NI}{NS}[/tex]
Here NI is Net income
NS is Net sales
Generally the profit of the retailer from the price of the phone is
[tex]PR = \frac{20}{100} * 150[/tex]
=> [tex]PR = \$ 30[/tex]
Generally the cost price for the retailer which is also the selling price of the distributor is
[tex]CR = 150 - PR[/tex]
=> [tex]CR = 150 - 30[/tex]
=> [tex]CR = $120[/tex]
Generally the profit for the distributor is
[tex]PD = \frac{30}{100} * 120[/tex]
[tex]PD = \$ 36[/tex]
Generally the cost price for the distributor which is also the selling price the manufacturer is
[tex]CD = CR - PD[/tex]
=> [tex]CD = 120 - 36[/tex]
=> [tex]CD = $ 84[/tex]
Generally the profit for the manufacturer is
[tex]PM = \frac{10}{100} * CD[/tex]
=> [tex]PM = \frac{10}{100} * 84[/tex]
=> [tex]PM = \$ 8.4[/tex]
Generally the target cost is mathematically represented as
[tex]T = CD - PM[/tex]
=> [tex]T = 84 - 8.4[/tex]
=> [tex] \$ 75.60 [/tex]

Answer:
m<2 = 134°
m<3 = 46°
m<4 = 134°
Step-by-step explanation:
Because of vertical angles theorem, m<1 is congruent to m<3.
to find the m<2 and m<4 you need to subtract 46 from 180.
because m<2 and m<1 are adjacent and on a transversal line, they are equal to 180°
