QUESTION 23
Tamara has $50 to spend on craft supplies. She spends $30
plus a 5% tax at the store. How much change should she
receive?

Answer:

$50

Step-by-step explanation:

5= 26+4=30

6=30+4=34

7=34+4=38

8=38+4=42

9=42+4=46

10=46+4=50

Rose would be saving 50 dollars after 10 months. At first Rose only had $10 in 0 months and $14 in the next month and again.This means that every month it adds up to another $4. If you want to find the total or 10 months keep on add 5 4 times which is 20. Then add 30 from the 0-5 months and which gives you $50. So Rose would be saving up 50 bucks in 10 months.

Answer:

y = -2x + 7

Step-by-step explanation:

to write the equation to this problem, we need to find the the y intercept, or the point where the line intersects the Y axis

a slope of -2 means that for every x unit in the positive x direction (right) two y units are moved in the negative Y direction (downward)

so if we subtract (go to the left) 1x that means we would also have to add (go up) 2y, which would leave us at the point (0,7)

now, an equation for a line is written as Y = MX + B

M = slope

B = y intercept

our slope, as we said before, is -2, and we found the Y intercept, 7, so now we can construct our equation

y = -2x + 7

Answer:

y= -2x + 7

57 for the third side

Step-by-step explanation:

a = √(c² - b²)

answer:

1/6, 0.25,  1/3,  5/12

step-by-step explanation:

whenever i have to order fractions least to greatest, i put them in decimal form. so 1/3 into a decimal would be 0.3333333; 5/12 into a decimal would be 0.4166666; 1/6 would be 0.1666666; and 0.25 is already a decimal. so it'd be 1/6, 0.25, 1/3, 5/12

ya you are right width is +5 and length is +2

Step-by-step explanation:

a)

first step: find the gradient slope of line AB

A(-1,-2) B(7,2)

gradient=change in y/change in x

M=[2-(-2)]/[7-(-1)

M=4/8

M=1/2

the gradient of the straight line is given by

M1*M2=-1

1/2*M2=-1

multiply both sides by the reciprocal of 1/2

2*1/2*M2=-1*2

M2= -2.

b)

first find the mind point of line AB

A(-1,-2) B(7,2)

M.P=(x1+x2)/2 ,(y+y2)/2

M.P=(-1+7)/2 ,(-2+2)/2

M.P=6/2 ,0/2

M.P=3,0

ALSO THE GRADIENT PERPENDICULAR TO LINE AB IS;

M= -2

equation of a line perpendicular to AB and passes through the midpoint of AB

Y-Y1=M(X-X1). (3,0). M=-2

y-0=-2(x-3)

y= -2x+6

Answer:

y = [tex]-\frac{4}{3}[/tex]x + 6

Step-by-step explanation:

y = mx + b

m: slope

b: y-intercept

y-intercept point on the graph is (0, 6) because it's the point that's on the y-axis.

Therefore, y-intercept is 6.

Slope: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Point A: (0, 6)

Point B: (4, -2)

Slope (m) = [tex]\frac{-2 - 6}{4 - -2}[/tex]

[tex]m = \frac{-2 - 6}{4 +2}[/tex]

[tex]m = \frac{-8}{6}[/tex]

[tex]m = -\frac{4}{3}[/tex]

y = [tex]-\frac{4}{3}[/tex]x + 6

Answer:

Step-by-step explanation:

Given the expression

3/5k - 5 = 7/10k

We are to find the value of k

Cross multiply

3(10k) = 7(5k-5)

30k = 25k - 35

30k - 25k = -35

5k = -35

k = -35/5

k = -7

Hence the value of k is -7

Answer:

y = 8x

Step-by-step explanation:

Given that :

Ornanment are packed in boxes

Number of ornament per box = 8

x = number of boxes packed

y = Number of ornaments

Number of Ornanments packed = (Number ornaments per box * number of boxes packed

y = 8 * x

y = 8x

All 3 sides of the triangle are identical so each interior angle is 60 degrees.

7x + 4 = 60

Subtract 4 from both sides:

7x = 56

Divide both sides by 7:

x = 8

Answer:

A negative integer

Step-by-step explanation:

3x - 2(5x+12) - 32 = 0

3x - 10x - 24 - 32 = 0

-7x -56 = 0

-7x = 56, x = -8

y = 5(-8) + 12, y = -28

Answer:

The leg-to-hypotenuse ratio is 1/√2

The ladder represents the longest length in the triangle.

Step-by-step explanation:

The set up in the question will b a right angled triangle

Length of the ladder will be the hypotenuse

The distance from the base of the wall to the base of the ladder  is the adjacent

Height of the wall will be the opposite

Note that the longest side is always the hypotenuse (length of the ladder)

Given

length of the ladder = 12foot

The distance from the base of the wall to the base of the ladder = 6√2

The ratio of leg to hypotenuse = 6√2/12 = √2/2

√2/2 = √2/2 * √2/√2

√2/2 = √4/2√2

√2/2 = 2/2√2

√2/2 = 1/√2

Hence the leg-to-hypotenuse ratio is 1/√2

From the calculation the following are correct:

the leg-to-hypotenuse ratio is 1/√2

The ladder represents the longest length in the triangle.

Answer:

The leg-to-hypotenuse ratio is 1/√2

The ladder represents the longest length in the triangle.

Answer:

A) -2.5

Step-by-step explanation:

You have to plug the x-value into the function.

f(x) = (1/2)x - 1

f(x) = 1/2(-3) - 1

f(x) = (-3/2) - 1

f(x) = -1.5-1

f(x) = -2.5

Answer:

The slope of the line = m = 2

Step-by-step explanation:

Taking two points from the line graph

Determining the slope between (0, 0) and (1, 2)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [2 - 0] / [1 - 0]

               = 2 / 1  

               = 2

Thus, the slope of the line = m = 2
