Susie tries to read 50 pages of her book every day.
One week (7 days) she only managed to read 280 pages.

Answers

Answer 1

Answer: 25%

Step-by-step explanation:

Approximate value = 350

Exact value = 280

The percentage error will be calculated by using the formula:

= (Approximate value - Exact value). Exact value × 100

= (350 - 280) / 280 × 100

= 70/280 × 100.

= 1/4 × 100

= 25%

Poppy has one bag of beads. She is going to make three difference necklaces.

For the first necklace, she needs 3/8 of a bag of beads. For the second, she

needs 1/8 of a bag of beads. For the third, she needs 5/8 of a bag. What

fraction of a bag of beads does she need? Does she have enough? Explain.

Answers

Answer:

9/8 of a bag

she doesn't have enough beads.

Step-by-step explanation:

Bag of bead poppy has = 1

Bag of bead needed for necklace 1 = 3/8 of a bag

Bag of bead needed for necklace 2 = 1/8 of a bag

Bag of bead needed for necklace 3 = 5/8 of a bag

Total bag of beads needed = 3/8 + 1/8 + 5/8

= (3+1+5)/8

= 9/8

She needs 9/8 of a bag of bead

9/8 = 1 1/8

Therefore, she doesn't have enough beads.

Answers

Answer:

(-4,9)

Step-by-step explanation:

To solve the system of equations, you want to be able to cancel out one of the variables. In this case, it'd be easiest to cancel out the x variables. To do this, you'll want to multiply everything in the first equation by 2 (2(x-5y=-49)=2x-10y=-98). Then, you can add the two equations together. 2x and -2x will cancel out, so you'll be left with -11y=-99. Next, solve for x by dividing both sides of the equation by -11, which will give you y=9. This is your y-coordinate! At this point, you're halfway to the answer as you just need your x-coordinate. It's not too difficult to find the x-coordinate, since you just substitute 9 into one of the equations. It doesn't matter which one you choose as you should get the same answer with both. I usually substitute the y-value into both equations, though, just to make sure I'm correct. Once you put the y-value into the equations, you should get x=-4 after solving it. :)

Answer:

Slope is equal to the change in y over the change in x , or rise over run.

m=change in y/ change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change  in y is equal to the difference in y-coordinates (also called rise).

m=y2−y1/x2−x1

Substitute in the values of x and y into the equation to find the slope.

m=0−(2)/9−(5)

Simplify.

A line passes through (2,4) and (-2,2)
a)Find the value of y if (6,y) lies on the
plane
b)Does this line pass through the point of
origin?
c)Does this tine intersect with the line
V=-X+32
d)lf your answer was yes in b, in which
quadrant did they intersect?​

Answers

Answer:

a) The value of [tex]y[/tex] is 6.

b) This line does not pass through the point of origin.

c) [tex]y = \frac{1}{2}\cdot x + 3[/tex] intersects with [tex]y = -x+32[/tex].

d) Both [tex]y = \frac{1}{2}\cdot x + 3[/tex] and [tex]y = -x+32[/tex] intersect in the first quadrant.

Step-by-step explanation:

a) By Analytical Geometry, we know that an equation of the line can be found by knowing the coordinates of two distinct points on the plane. The equation of the line is defined by this formula:

[tex]y = m\cdot x + b[/tex] (1)

Where:

[tex]x[/tex] - Independient variable.

[tex]y[/tex] - Dependent variable.

[tex]m[/tex] - Slope.

[tex]b[/tex] - x-Intercept.

To determine the slope and x-intercept of the equation of the line, we have to solve the following system of linear equations:

[tex]m\cdot x_{1}+b = y_{1}[/tex] (2)

[tex]m\cdot x_{2}+b = y_{2}[/tex] (3)

If we know that [tex](x_{1}, y_{1} ) = (2,4)[/tex] and [tex](x_{2}, y_{2}) = (-2, 2)[/tex], then the solution of the system is:

[tex]m = \frac{1}{2}[/tex], [tex]b = 3[/tex]

Then, the equation of the line is [tex]y = \frac{1}{2}\cdot x + 3[/tex]. If we know that [tex]x = 6[/tex], then the value of [tex]y[/tex] is:

[tex]y = 6[/tex]

The value of [tex]y[/tex] is 6.

b) If this line passes through the point of origin, then the value of [tex]y[/tex] must be zero for [tex]x = 0[/tex]. If we know that  [tex]y = \frac{1}{2}\cdot x + 3[/tex] and [tex]x = 0[/tex], then the value of [tex]y[/tex] is:

[tex]y = 3[/tex]

The line does not pass through the point of origin since x-intercept is not zero.

c) A system of two linear equations always has an unique solution if and only if slopes and x-intercepts are different to each other. This condition is satisfied by [tex]y = -x+32[/tex], so we conclude that both lines intersect each other.

d) (Note: Question was incorrectly written. Correct form is: If your answer was yes in c, in which quadrant did they intersect?)

First, we solve the following system of linear equations:

[tex]\frac{1}{2}\cdot x -y = -3[/tex] (4)

[tex]-x-y = -32[/tex] (5)

The solution of this system is [tex](x,y) = (19.333, 12,667)[/tex], which means that both lines intersects each other in the first quadrant.

Answer:

x = 9

m∠1 = m∠2 = 54°

Step-by-step explanation:

Two lines r and s are the parallel lines and a transversal line is intersecting these lines at two distinct points.

a). ∠1 ≅ ∠2 [Corresponding angles]

    Therefore, m∠1 = m∠2

    (63 - x)° = (72 - 2x)°

    2x - x = 72 - 63

    x = 9

b). m∠1 = (63 - x)°

            = 63 - 9

            = 54°

    m∠2 = (72 - 2x)°

             = 72 - 18

             = 54°

Answer:

La²+8La+16 = La²+70

Step-by-step explanation:

8La+16 = 70

8La=70-16

La=54/8

La= 6.75

Area b = (6.75+4)*(6.75+4)

Area b = 10.75*10.75

Area b =115.563

The area of a square is the square of its side lengths

The area of square B is 116 centimeter square

Let the side length of square A be (a), and the side length of square B be (b)

So, we have:

[tex]\mathbf{A_a = a^2}[/tex]

[tex]\mathbf{A_b = b^2}[/tex]

From the question, we have:

[tex]\mathbf{A_b = 70 + a^2}[/tex]

[tex]\mathbf{b = 4 + a}[/tex]

Take square of both sides

[tex]\mathbf{b^2 = (4 + a)^2}[/tex]

[tex]\mathbf{b^2 = 16 + 8a+ a^2}[/tex]

Substitute [tex]\mathbf{b^2 = 16 + 8a+ a^2}[/tex] in [tex]\mathbf{A_b = b^2}[/tex]

[tex]\mathbf{A_b = 16 + 8a+ a^2}[/tex]

So, we have:

[tex]\mathbf{16 + 8a+ a^2 = 70 + a^2}[/tex]

Subtract a^2 from both sides

[tex]\mathbf{16 + 8a = 70}\\[/tex]

Subtract 16 from both sides

[tex]\mathbf{8a = 54}[/tex]

Divide both sides by 8

[tex]\mathbf{a = 6.75}[/tex]

Recall that:

[tex]\mathbf{A_b = 70 + a^2}[/tex]

So, we have:

[tex]\mathbf{A_b = 70 + 6.75^2}[/tex]

[tex]\mathbf{A_b = 115.5625}[/tex]

Approximate

[tex]\mathbf{A_b = 116}[/tex]

Hence, the area of square B is 116 centimeter square

Answer:

∠S = 151°

Step-by-step explanation:

Hello there!

This is an irregular pentagon

If you didn't know the sum of the interior angles add up to equal 540

We must solve for x to be able to find the measure of angle S

we can use this equation to solve for x

540 = 5x + 2 + 10x - 3 + 7x - 11 + 13x - 31  + 8x - 19

step 1 combine like terms

2 - 3 - 11 - 31 - 19 =-62

5x + 10x +7x + 13x + 8x = 43x

so now we have

540 = 43x - 62

step 2 add 62 to each side

-62 + 62 cancels out

540 + 62 = 602

now we have

602 = 43x

step 3 divide each side by 43

43x/43 = x

602/43=14

we're left with x = 14

Now we want to plug in x for angle S

13(14) - 31

13*14=182

182-31=151

So we can conclude that the measure of angle S is 151 degrees
