PLS HELP ALGEBRA 1 LINEAR FUNCTIONS QUESTION
(ONLY number 4 pls, it wouldn’t let me crop it)

Answer:

x=20

Step-by-step explanation:

Step-by-step explanation:

<A + < B = 90° { being complementary angles)

2x + 10° + 3x + 15° = 90°

5x = 90° - 15° - 10°

5x = 65°

x = 13°

Now

<B = 3x + 15° = 3 *13° + 15° = 54°

Hope it will help :)

Answer:

Tris-HCl (0.5M Tris Base, pH7.6):

Trizma Base ---------------------------------- 61 g

Distilled water ------------------------------- 1000 ml

Adjust pH 7.6 using concentrated HCl

Store this solution at room temperature. Dilute 1:10 with distilled water before use

and adjust pH if necessary.

20X Tris-HCl (1M Tris Base, pH7.6):

Trizma Base ---------------------------------- 122 g

Distilled water ------------------------------- 1000 ml

Adjust pH 7.6 using concentrated HCl

Store this solution at room temperature. Dilute 1:20 with distilled water before use

and adjust pH if necessary.

10X Tris-HCl-Tween 20 (0.5M Tris Base, 0.5% Tween 20, pH7.6):

Trizma Base ---------------------------------- 61 g

Distilled water ------------------------------- 1000 ml

Adjust pH 7.6 using concentrated HCl and then add 5 ml of Tween 20.

Store this solution at room temperature. Dilute 1:10 with distilled water before use

and adjust pH if necessary.

Note: Tris-HCl Buffer is used for specific cases of immunohistochemical staining.

*** OR you can use Tris Base to make Tr

I don't know if you need help, but the answer to the question in the picture is indeed A. :)

Answer:

88

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

For these problems you should use the pythagorean theorem: a^2+b^2=c^2

In this case, 13=c and 5=a

so:

5^2+x^2=13^2

25+x^2=169

subtract 25 from both sides

x^2=144

√144=12

missing side=12

Answer:

Assuming the question is about the area of the "house" it's 70.

Step-by-step explanation:

The triangle's height is 18 - 10 = 8

The area of the rectangle is 5 * 10 = 50

The area of the triangle is 5 * 8 / 2 = 20

The total area is 50 + 20 = 70

Answer:

Identifying at least one confounding variable that undermines the conclusion drawn in the fictional study is:

All students took the same comprehensive test.

Step-by-step explanation:

In a study, an independent variable causes an effect on the dependent variable. But a confounding variable is the variable that influences the independent variable as well as the dependent variable.  If this third variable is not controlled, it might lead the researcher to make a wrong estimate of the relationship that exists between the independent variable and the dependent variable.

Answer:

y = 1/10x

Step-by-step explanation:

We see that it intersects points (60,6), (120,12), and (0,0)

y = mx + b

m = 6/60 = 1/10

b = 0

y = 1/10x

The "M" in M-value stands for "Maximum." For a given ambient pressure, an M-value is defined as the maximum value of inert gas pressure (absolute) that a hypothetical "tissue" compartment can "tolerate" without presenting overt symptoms of decompression sickness (DCS).

Answer:

Infinite number of solutions

Step-by-step explanation:

Write these equations in a column:

-6x+y=-21  

2x-1/3y=7

Use elimination by addition and subtraction. Start by multiplying the 2nd equation by 3, obtaining:

-6x+y=-21  

6x - y= 21

----------------

  0  - 0 = 0

There are an infinite number of solutions.  The two equations shown immediately above are multiples of one another.

Answer:

17 is your answer

Step-by-step explanation:

Given a peicewise function, with two parts:

{f(x) = 4x+3 {if x<2}

f(x) = 5x+2 {if x>2}

f(3) = f(x) when x is 3, 3 > 2, 3 is not less than 2 so f(x) for x>2 is 5x + 2.

Therefore f(3) = 5(3) + 2 = 15 + 2 = 17

Answer: 17.7

Step-by-step explanation:

5( y + 2/5) = -13

Distribute the 5 by multiplying the 5 by each term inside the set of parentheses:

5y + 2 = -13

Subtract 2 from both sides:

5y = -15

Divide both sides by 5:

Y = 3

The answer is y = 3

Answer:

178.64 square cm

Step-by-step explanation:

5.8 x 8.8 x 2 = 102.08

8.8 x 8.7 = 76.56

76.56 + 102.08 =

178.64

Hope that helps!

Step-by-step explanation:

Given

x - 2.6 = 1.8

x = 1.8 + 2.6

x = 4.4

Hope it will help :)

Answer:

1.8+2.6=x

x=4.4 is the answer

Answer:

the answer is 4w-14=14 w=7

Answer:

12 ×$0.75 =$8.00

3.75 ÷ 5 = $1.33 a pound,

$1.33 × 12 = $15.96 so store A is offering the best rate.

It is found that Store B is offering the best unit rate for the bananas.

There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.

Given that Grocery Store A is selling bananas 1/2 pound for $0.75 .

Grocery Store B is selling 5 pounds of bananas for $3.75.

According to the question,

Store A is selling bananas 1/2 pound for $0.75 .

Therefore,

For one pound will be;

= 0.75/0.5

= 1.5

And store B is selling 5 pounds of bananas for; $3.75

Therefore,

One pound will cost;

3.75/ 5 = 0.75

Hence, Store B is offering the best unit rate for the bananas.

Answer: 0.3 meters.

Step-by-step explanation:

First we need to turn one of those into a fraction or decimal to make things easier for us. Lets turn [tex]1 \frac{1}{5}[/tex] into a decimal.

1 1/5 as a decimal is 1.2.

Now we compare the two

[tex]1.5 > 1.2[/tex]

Now we need to subtract 1.5 by 1.2 to see how much more he jumps by.

[tex]1.5 - 1.2 = 0.3[/tex]

Steve jumps more by 0.3 meters.

Answer:

3/10 or .3 meters

Step-by-step explanation:

1 1/5 = 1.2

1.5 - 1.2 = 0.3
