x² - 7x+10=0

Answers

Answer 1

Answer:

x²-7x+10=0
x²-5x-2x+10=0
x(x-5)-2(x-5)=0
(x-2)(x-5)=0 ANS!

Step-by-step explanation:

First we will multiply x² into 10, the answer will be 10x². Now, take L.C.M of 10, the L.C.M will be 5x2 or 2x5. Now we will make sure that:
2x x 5x=10x² while 5x+2x=7x. Now, we know that 7x is in negative so, we will change the signs and it will become x²-5x-2x+10=0. Now take common:
x(x-5)-2(x-5)=0. Now, write the common taken numbers first and then the other brackets in last i.e: (x-2)(x-5)=0

Answer:

32 C

Step-by-step explanation:

According to celsius conversion formula:

C = 5/9*(F-32)

= 5/9*(89-32)

= 5/9*57

Hence, C = 31.666

Rounding it off to the nearest whole number, the answer is 32 C.

The hypotenuse of a right triangle measures 6cm and one of its legs measures 3cm.Find the measure of the other leg. If necessary, round to the nearest tenth.

Answers

Answer:

5.2

Step-by-step explanation:

a^2+b^2=c^2

Where c is the length of hypotenuse

and a, b are lengths of the legs.

Put in 6 for c,

Put in 3 for a and you get 9+b^2=36

Subtract 9 from both sides and get b^2= 27

Then find the square root of both sides to get b, so the answer is the square root of 27.

The cloest square root is 5, then apporixmate the tenths value and see if they work.

Answer: 5.2

Answer:

square root of 27, 5.2

Step-by-step explanation:

(I know I'm late but-)

We know that 2+2 is 4.

Therefore, the legnth, a, is half of thirty.

30/2 = 15

a = 15

Answer:

[tex]\bf a= 15\;\; millimetetrs[/tex]

Step-by-step explanation:

perimeter: 34 millimetetrs

perimeter= [tex]\tt a+2+a+2=34[/tex]

[tex]\tt 2a+4=34[/tex]

[tex]\tt 2a+4-4=34-4[/tex] (Subtract 4 from both sides)

[tex]\tt 2a=30[/tex] (Simplify)

[tex]\tt \cfrac{2a}{2}=\cfrac{30}{2}[/tex] (Divide both sides by 2)

[tex]\tt a=15[/tex]

Therefore, a= 15 millimetetrs.

Mathew finds the deepest part of the pond to be 185 meters
Which measurement describes the depth of the pond?

Answers

[tex]\sqrt{196} = 14[/tex], and since [tex]\sqrt{185[/tex] is less than [tex]\sqrt{196}[/tex], the deepest part of the pond is less than 14.

-> The depth of the pond is between 13 and 14 meters.

Or, you can just calculate [tex]\sqrt{185}[/tex] = 13.6014... (between 13 and 14)

The measurement describes the depth of the pond is Between 13 and 14 meters.

What is Pythagoras Theorem?

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Since one side measure 14, and the height (depth) could not be higher than 14 meters .

The length of the pond can be calculated using the Pythagorean theorem as;

length^2 = 36^2 + 14^2

length^2 = 1296 + 196

length^2 = 1492

length = 38.6 m

26

Step-by-step explanation:

as the ratio is given you should divide ratio of boys by total ratio and multiply it by the total number of students, kinda like how in percentages you divide partial value/total value x 100, just in this case the total is 45 instead of 100. So [tex]\frac{4}{7} * 45[/tex] = 25.7 which have to be rounded to 26

Which scatterplot shows a linear association?

Answers

Answer:

B

Step-by-step explanation:

A linear association means the function is a relation that can be shown with a line.

The first scatterplot is in the form of a parabola, and parabolas are the quadratic function form, meaning it cannot be linear.

Next, the second scatterplot goes diagonally, in a straight line. If we were to connect the dots using a line, then it would be a linear association, meaning that B is the correct answer.

[tex]\sqrt[3]{3x}[/tex] + 7 = 4 ( subtract 7 from both sides )

You have 2 choices of bread: wheat or white; 3 choices of meat: ham, chicken, or beef; and 3 choices of condiments: mustard, mayo, and ketchup. If you choose each item at random, what is the probability that you will make a sandwhich with wheat bread, ham, and mustard?

Answers

Answer:

1/18

Step-by-step explanation:

Use the counting principle to find the total number of different sandwiches you can make.

2 breads

3 meats

3 condiments

Total number of different sandwiches = 2 × 3 × 3 = 18

There are 18 possible sandwiches.

You are intereseted in 1 specific sandwich out of the 18.

p(wheat bread, ham, mustard) = 1/18

1/18 is the probability that you will make a sandwich with wheat bread, ham, and mustard.

What is a number?

A number is an arithmetic value used to represent quantity.

We can use the counting principle to find the total number of ways to make different sandwiches.

2 breads, 3 meats, and 3 condiments.

Total number of sandwich varieties = 2* 3* 3 = 18

There are 18 possible sandwiches.

You're only interested in one of the 18 sandwich varieties.

i.e.   p(wheat bread, ham, mustard) = 1/18

Hence, the probability that you will make a sandwich with wheat bread, ham, and mustard is 1/18.

Find the value of X
Find the measures of the following angles

Answers

Answer:

angle X = 80; angle Y = 100; angle W = 100; x = 10

Step-by-step explanation:

opposite angles are always equal, which means that angle Z and angle X are equal.

angle X = 80º

now, angle Z plus angle Y makes a straight line, which means 180º (if you put the two angles next to each other)

that means 80 + (11x - 10) = 180

11x = 110

x= 10

by using this, we can find angles Y and W since opposites are equal

11x - 10 would be 100 and angles Y and W would be 100
