Tom walks 3. 15 km to the park. He then walks a further 350 m to the shop. How many km has Tom walked in total?

Answers

Answer:

Step-by-step explanation:

We have to convert m to km and we have to add to find the total distance walked.

1000m = 1 km

350 m = 350 ÷ 1000 = 0.35 km

Total distance = 3.15 + 0.35

                        = 3.50 km

factorise: y² + 4y - 21​

Answers

Answer:

[tex](y+7)(y-3)[/tex]

Step-by-step explanation:

To factorize [tex]y^2+4y-21[/tex]

[tex]\textsf{for} \ ax^2+bx+c \ \textsf{find} \ v, w \ \textsf{such that} \ v \cdot w=a \cdot c \ \textsf{and} \ v+w=b\\ \textsf{ and group into} \ (ax^2+vx)+(wx+c)[/tex]

[tex]a \cdot c=1 \cdot -21=-21[/tex]

[tex]b=4[/tex]

Therefore, the 2 numbers that multiply together to give -21 and add together to give 4 are:  7 and -3

[tex]\implies y^2+7y-3y-21[/tex]

[tex]\implies (y^2+7y)+(-3y-21)[/tex]

Factor the parentheses:

[tex]\implies y(y+7)-3(y+7)[/tex]

Factor out the common term [tex](y+7)[/tex]:

[tex]\implies (y+7)(y-3)[/tex]

A segment has one endpoint at the origin O and the other endpoint at A(12,36). If point B is located on OA such that OA/BA=3 then which of the following are the coordinates of B?
(1) (4,12) (2) (9,27) (3) (8,24) (4) (36,108)

Answers

The distance between (8, 24) and (12, 36) is one-third of the distance between (0, 0) and (12, 36).

How to find the coordinates of point B?

We know that:

O = (0, 0)A = (12, 36).

And point B is between these two, such that:

OA/BA = 3

Meaning, OA is 3 times BA.

Now, if we apply a factor of 1/3 to point A, we get:

(12/3, 36/3) = (4, 12)

So, the distance between A and B is equal to the distance between the origin and (4, 12) (a change of 4 units in the x-component and 12 units in the y-component).

The point that meets that condition is (8, 24), which is given by multiplying by 2 the previous coordinates.

The distance between (8, 24) and (12, 36) is one-third of the distance between (0, 0) and (12, 36).

Solve the inequality b - 12 > -3
What are the solutions?

Answers

Answer:

b>9

Step-by-step explanation:

Answer:

b > 9

Step-by-step explanation:

Inequalities represent the value of a variable in relation to other numbers.

Solving the Inequality

The properties of equality state that if you add or subtract a number from both sides, the statement remains true. This means that we can isolate the variable by using the properties of equality.

To isolate the variable, add 12 to both sidesThis gives the inequality b > 9

Understanding the Answer

The answer to the inequality is b > 9. This means that the variable must be greater than 9. So, values such as 10 or 100 could all be solutions. However, remember that 9 itself is not a solution. The inequality only accounts for values greater than 9, not equal to.

what's better 27 out of 32 or 19 out of 21 and why

Answers

27 out of 32

Because the higher the score the less the points is gonna worth. So if you get one wrong, it wouldn’t hurt your score that much

Answer:

19/21 is better.

Step-by-step explanation:

To find which is better, you need to divide the numerator by the denominator.

27 divided by 32 is equal to 0.84375

19 divided by 21 is equal to 0.9

0.9 is greater than 0.84375, so 19/21 is better.

Answers

Answer:

Step-by-step explanation:

To get  how far up the tree that Mr. Jones tied the rope, we will use the Pythagoras theorem since a right angle is created with the rope and the base of the tree.

The length of the rope will be the hypotenuse

The distance up the tree and away from the base will be the opposite and adjacent.

Given

length of the rope = 8feet

Distance away from the base of the tree = 6ft

According to Pythagoras;

hyp² = opp²+adj²

8² = opp²+6²

opp² = 8²-6²

opp² = 64-36

opp² = 28

opp = 5.3 feet

Hence the Mr Jones tied the rope 5.3feet above the tree. Option C is correct

Slopes step by step

Answers

Answer:

1 is y=-1/3x. 3 is y=-3/2x. 5 is y=5/3x

Step-by-step explanation:

Simply count the vertical lengths. Meaning count up or down how ever many. That is your top number. Then count your horizontal lengths, meaning left or right, this your bottom number of the slope. So if point A is at (-1,-1) in example 1, then count down 1, and right 3 spaces. Because you go down, the slope is negative, and you went down 1, so the top number is 1, you went right 3 units, so the bottom number is 3.
