Emily estimated it would take her 40 minutes to run 3 miles. It actually took her 30 minutes. What was Emily's percent of error for the time she estimated to run 3 miles? A. 26.7% B. 25.0% C. 33.3% D. 10.0%
Answer:
C. 33.3%
Step-by-step explanation:
Estimated time = 40 minutes
Actual time = 30 minutes
Percent of error = (estimated time - actual time) / actual time × 100
= (40 minutes - 30 minutes) / 30 minutes × 100
= 10 minutes / 30 minutes × 100
= 0.3333 × 100
= 33.3%
Percent of error = 33.3%
C. 33.3%

90 students are participating in a contest. There are twice as many girls as boys in this group. Max ranks fourteenth from the top, and there are 10 girls who rank higher than him. How many boys rank lower than Max?
Answer: 57 boys
Step-by-step explanation: Lets break it down right
14th from the top with 10 girls in front which means 3 boys are in front and since there are twice as many girls as boys there are 60 girls and 30 boys so 3 boys are ahead which leaves 57 boys below him
If you cut away a triangle of area 59cm^2,the remaining area will be 85cm^2.Find the length of the side of the square before it was cut.?
Please help me. Thank you
Answer:
AE - 3, EB - 2, EC - 5
Step-by-step explanation:
Use the Pythagorean theorem and you'll find that these are the answers.
I'll answer problem 19
=======================================================
Part (a)
The tickmarks on segments DE and DC indicate they are the same length. We're also told that |DC| = |DE| = 5.
So DE is also 5 cm long. Triangle DAE is a right triangle with the 90 degree angle at angle A. Let x be the length of segment AE.
We'll use the pythagorean theorem to find x
a^2 + b^2 = c^2
(AE)^2 + (AD)^2 = (DE)^2
x^2 + 4^2 = 5^2
x^2 + 16 = 25
x^2 = 25-16
x^2 = 9
x = sqrt(9)
x = 3
Segment AE is 3 cm long
=======================================================
Part (b)
For any rectangle, the opposite sides are parallel and the same length. This means AB = DC = 5 cm.
We found earlier that AE = 3 cm, so,
AE+EB = AB
3+EB = 5
EB = 5-3
EB = 2
Segment EB is 2 cm long
=======================================================
Part (c)
We know that AD = BC = 4 cm, because the opposite sides are the same length.
Earlier in part (b), we found that segment EB was 2 cm long.
Triangle EBC is a right triangle with legs EB = 2 and BC = 4. Let's apply the pythagorean theorem to find EC. Let y = EC.
a^2 + b^2 = c^2
(EB)^2 + (BC)^2 = (EC)^2
2^2 + 4^2 = y^2
4 + 16 = y^2
20 = y^2
y^2 = 20
y = sqrt(20)
y = sqrt(4*5)
y = sqrt(4)*sqrt(5)
y = 2*sqrt(5)
y = 4.4721359
As an exact value, EC is sqrt(20) or 2*sqrt(5) cm long.
As an approximate value, EC is roughly 4.4721359 cm long.
I would ask your teacher if you should use the exact or approximate value.
What is the value of x in the triangle? A. 21 B. 10 C. 7 D. 7√3
Find the area of the figure.
Answer:
33 sq units
Step-by-step explanation:
if you section it off into a rectangle and two triangles, the large rectangle that makes up most of the shape is 6x4 units or 24 sq units. each triangle is 3x3 units, so together they would make one 3x3 square. the 3x3 square would have an area of 9, and the answer is 24+9, or 33 sq units

How to find the slope and y intercept from two coordinate pairs
Answer:
Slope: y2-y1/x2-x1
Step-by-step explanation:
You find slope from two coordinate pairs by using the slope formula(y2-y1/x2-x1) or rise over run from a graph.
To find y-intercept, x needs to be 0 on a graph.

Step-by-step explanation:
A tank contains 3000 L of pure water. Brine that contains 15 g of salt per liter of water is pumped into the tank at a rate of 25 L/min. The concentration of salt after t minutes (in grams per liter) is C(t) = 15t 120 + t . As t → [infinity], what does the concentration approach? g/L
Answer:
15 g/L
Step-by-step explanation:
Since Brine is added to the tank containing 15g/L at a rate of 25 L/min, the rate at which the quantity of salt in the tank increases is 15 g/L × 25 L/min = 375 g/min. So, in t minutes, the mass of salt in the tank, m is 375 g/min × t min = 375t
Also, the volume of the tank increases by 25 L/min, in t minutes, its volume increases by 25 L/min × t min = 25t. So, the new volume, V is 3000 + 25t.
Since we know, concentration C(t) = m/V = 375t/(3000 + 25t)
dividing through by 25, we have
C(t) = 375t/25/(3000/25 + 25t/25)
C(t) = 15t/(120 + t)
To find the limit as t ⇒ ∞, we divide C(t) by t
C(t) = 15t/t/(120/t + 1)
C(t) = 15/(120/t + 1)
putting t = ∞, we have
C(∞) = 15/(120/∞ + 1)
C(∞) = 15/(0 + 1)
C(∞) = 15/1
C(∞) = 15 g/L
So, as t t → [infinity], the concentration approaches 15 g/L

A Starbucks manager has x pounds of coffee in stock. He sells 15 pounds and then
receives a shipment weighing 2y pounds. Which expression represents the weight of the
has?
Highlight
X-15-2y
O X+ 15 + 2y
O
x + 15 - 26
O
X - 15 + 2y
Answer: x - 15 + 2y
Step-by-step explanation:
A Starbucks manager has x pounds of coffee in stock and then sells 15 pounds. The amount of pounds of coffee left will be:
= x - 15
He then receives a shipment weighing 2y pounds. This means that the weight of the coffee he has will then be:
= x - 15 + 2y
The area of this trapezoid is what?
Answer:
The area of this trapezoid is 8cm
Answer:
130
Step-by-step explanation:
first decompose the trapezoid into a square in the middle and 2 triangles on the left/right side, both triangles are congruent so you only find the area of one triangle, which is 9 because do 2x9 = 18/2 = 9, now let's move on to the middle square 14 x 18 = 112, then you add them all up remember there are 2 triangles,
112 + 9 + 9 = 130

Write the rule of the transformation
Answer:
(x + 5, y + 1)
Step-by-step explanation:
As we can see, what we have is a translation
let us pick a point
G( -5,-2)
To;
G’(0,-1)
so the shift on the x-axis is;
(0-(-5)) = 5
shift on the y-axis is;
(-1-(-2) = 1
we have a rightward shift of 5 units on the x-axis and 1 unit on the y-axis
So we have the rule as;
(x + 5, y + 1)

identify the area of the figure rounded to the nearest tenth
Answer:
71.4 in ^2
Step-by-step explanation:
area of the circles = πr^2
3.14(4x4) = 50.24 but you only have half so divide by 2
= 25.12
second circle
3.14(2x2)= 13.56 again you only have half so divide by 2
= 6.28
square
5x8 = 40
add them all up
25.12+6.28+40 = 71.4
