Answer:
The height of the candle after 7 hours is 21.3 centimeters.
Step-by-step explanation:
From the information given you can assign the following values:
x1=10; y1=21
x2=28; y2=19.2
First, you have to find the slope using the following formula:
m=[tex]\frac{y2-y1}{x2-x1}[/tex]
m=[tex]\frac{19.2-21}{28-10}[/tex]
m=-0.1
Then, you can find the equation using the point/slope formula:
y-y1=m(x-x1)
y-21=-0.1(x-10)
y-21=-0.1x+1
y=-0.1x+22
Finally, to find the answer you need to replace the value of x that would be 7 in y=-0.1x+22:
y=-0.1(7)+22
y=-0.7+22
y=21.3
According to this, the height of the candle after 7 hours is 21.3 centimeters.

lin and her brother each dreated a scale drawing of their backyard, but at different scles. lin used a scale of 1 inch to 1 foot. her brother used a scale of 1 inch to 1 yard
1. express the scales for the drawings without units
2.whose drawing is larger? how mnay times as large is it? explain or show your reasoning
Answer:
Kindly check explanation
Step-by-step explanation:
Given:
Lin's drawing = 1 inch to 1 foot
Brother's drawing = 1 inch to 1 yard
1.) express the scales for the drawings without units
Convert both foot and yard to inch
1 foot = 12 inches
1 yard = 36 inches
Hence,
Lin's drawing : 1 : 12
Brother's drawing : 1 : 36
2.) whose drawing is larger? how mnay times as large is it? explain or show your reasoning
Lin's drawing is larger, this is because in Lin's drawing every 12 inch in the actual drawing represents 1 inch in the scale drawing( model)
While the brother's drawing is smaller with 36 inches in the actual drawing represented as 1 inch in the scale drawing.
(1/12) ÷ (1/36)
1/12 * 36/ 1
= 36 / 12
= 3. ; 3 times larger
whats the definition of nuts cells
Answer:
A nut is a fruit composed of an inedible hard shell and a seed, which is generally edible. In general usage and in a culinary sense, a wide variety of dried seeds are called nuts, but in a botanical context "nut" implies that the shell does not open to release the seed (indehiscent). The translation of "nut" in certain languages frequently requires paraphrases, as the word is ambiguous.

3.) 4x + 6 = 14
Answer:
x=2
Step-by-step explanation:
4x + 6 = 14
4x = 14 - 6
4x = 8 (divide both sides by 4 to get x)
4x/4 = 8/4
x = 2
Answer:
Subtract 6 from both sides of the equation
4+6−6=14−6
Simplify
Subtract the numbers
4x+6−6=14−6
4=14−6
Subtract the numbers again
4x=14−6
4=8
Divide both sides of the equation by the same term
4=8
4 4
Cancel terms that are in both the numerator and denominator
x= 8

Find the equation of the linear function represented by the table below in slope-intercept form.
x y
1 0
2 -3
3 -6
4 -9
Answer:
The equation is y = - 3x + 3
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptThe rule of the slope is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]→ The table has 4 point: (1, 0), (2, -3), (3, -6), (4, -9)
→ We will choose two of them to find the slope
∵ The points (1, 0) and (2, -3) lie on the line
∴ [tex]x_{1}[/tex] = 1 and [tex]x_{2}[/tex] = 2
∴ [tex]y_{1}[/tex] = 0 and [tex]y_{2}[/tex] = -3
→ Substitute these values in the rule of the slope above
∴ [tex]m=\frac{-3-0}{2-1}=\frac{-3}{1}=-3[/tex]
∴ m = -3
→ Substitute the value of the slope in the form of the equation
∴ y = - 3x + b
→ To find b substitute x and y by the coordinates of a point on the line
∵ x = 1 and y = 0
∴ 0 = - 3(1) + b
∴ 0 = - 3 + b
→ Add 3 to both sides
∴ 0 + 3 = -3 + 3 + b
∴ 3 = b
∴ b = 3
→ Substitute the value of b in the form of the equation above
∴ y = -3x + 3
The equation is y = - 3x + 3
Answer:
y=-3x+1
because the slope is going up not down.

What is the equation of a line through point (-4,5) that is perpendicular
to the line with equation y= -6x+4?*
Answer:
set two equation of line y=ax+b and y=cx+d
when these two lines are perpendicular to each other, then a*c=(-1)
set answer is y=ax+b
we can know that a=1/6
bring in a=1/6 and(-4,5)
5=(1/6)*(-4)+b
=>5=(-2/3)=b
=>b=5 2/3
answer is y=(1/6)x+5 2/3

0.5(5 - 7b) = 8 - (4b + 6)
Answer:
b=-1
Step-by-step explanation:
Let's solve your equation step-by-step.
0.5(5−7b)=8−(4b+6)
Step 1: Simplify both sides of the equation.
0.5(5−7b)=8−(4b+6)
0.5(5−7b)=8+−1(4b+6)(Distribute the Negative Sign)
0.5(5−7b)=8+−1(4b)+(−1)(6)
0.5(5−7b)=8+−4b+−6
(0.5)(5)+(0.5)(−7b)=8+−4b+−6(Distribute)
2.5+−3.5b=8+−4b+−6
−3.5b+2.5=(−4b)+(8+−6)(Combine Like Terms)
−3.5b+2.5=−4b+2
−3.5b+2.5=−4b+2
Step 2: Add 4b to both sides.
−3.5b+2.5+4b=−4b+2+4b
0.5b+2.5=2
Step 3: Subtract 2.5 from both sides.
0.5b+2.5−2.5=2−2.5
0.5b=−0.5
Step 4: Divide both sides by 0.5.
0.5b/0.5=−0.5/0.5
b=−1

An investor invested a total of $14,000. She divided the money into three different accounts. At the end of the year, she had made $670 in interest. The annual yield on each of the three accounts was 4%, 5%, and 6%. If the amount of money invested in the 5% account was the same as the combined amount invested in the 4% and the 6% accounts, determine how much was invested in the account that paid 6% interest.
Answer:
$2000
Step-by-step explanation:
Given the following :
Total amount invested = 14000
Total interest earned = 670
Amount invested in 4% (0.04) account = a
Amount invested in 6% (0.06) account = b
Amount invested in 5% (0.04) account = a + b
a + b + (a + b) = 14000
2a + 2b = 14000
a + b = 7000 - - - (1)
Simple interest = principal * rate * time
(a * 0.04) + (b * 0.06) + [(a+b) * 0.05] = 670
0.04a + 0.06b + 0.05a + 0.05b = 670
0.09a + 0.11b = 670 - - - - (2)
from (1)
a = 7000 - b
0.09(7000 - b) + 0.11b = 670
630 - 0.09b + 0.11b = 670
= 630 + 0.02b = 670
0.02b = 670 - 630
0.02b = 40
b = 40/ 0.02
b = $2000
Amout invested in 6% account = $2000

71 ×10 ^ 3 Scientific Notation
Answer:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 1010. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
7.1×1047.1×104
