Mrs. Barlow's math class took a test yesterday. Out of 100 students, 70% of them passed. How many of Mrs. Barlow's students passed the test?
Answer:
70
Step-by-step explanation:
70 percent of 100 is [tex]\frac{70}{100}[/tex]
so [tex]\frac{70}{100}[/tex] × 100 students
= 70 students
What is the quotient of 5 7 ÷ 5 14 ?
Answer:
= 57 / 514 (Decimal: 0.110895)Step-by-step explanation:
57 / 514
= 57 / 514
(Decimal: 0.110895)
And if that is not what you are looking for here:
Rewrite the equation as
x /14 = 5/ 7 . x/ 14 = 5/ 7
Multiply both sides of the equation by
14.14 ⋅ x /14 = 14 ⋅ 5 /7
Simplify both sides of the equation.
Tap for fewer steps...
Cancel the common factor of 14 .
Cancel the common factor.
14 ⋅ x /14 = 14 ⋅ 5 /7
Rewrite the expression.
x = 14 ⋅ 5 /7
Simplify 14 ⋅ 5/ 7 .
Cancel the common factor of 7 .
Factor 7 out of 14 .
x = 7 ( 2 ) ⋅ 5/ 7
Cancel the common factor.
x = 7 ⋅ 2 ⋅ 5/ 7
Rewrite the expression.
x = 2 ⋅ 5
Multiply 2 by 5 .
x = 10

It cost Jayden $4.80 to send 96 text messages. How much would it cost to send 155 text messages?
Answer:
$7.75
Step-by-step explanation:
1. Take the cost - $4.80 for the 96 messages, and divide $4.80 by 96 to get the cost per message.
2. 4.80 ÷ 96 = $0.05 per message
3. Take that figure and multiply by 155 messages.
4. 155 × $0.05 per message = $7.75
Hope this helps!

Simplify: 4 3/2
Answer:
4 3/2 is simplified into 5 1/2
Step-by-step explanation:
There are three halves in the improper fraction 3/2. Two of those halves make another whole number, and you are left with one half and 1. 4 + 1 1/2 is equal to 5 1/2.

I have a problem, it says, identify the set of numbers that best describes each situation. The situation is, the amount of money in a bank account. we are working with, real, rational, irrational, integers, and whole numbers. Is it irrational or rational?
Answer:
Rational
Step-by-step explanation:
We first have to define what these numbers mean:
Real numbers are all the numbers on the number line, they are not imaginary numbers that cannot be quantified on the number line.
Rational numbers are numbers that have either terminating decimals or recurring decimal, for example 5.3 (terminating decimal) or 1.333...(recurring decimal). I did not use the traditional definition of "a/b where a and b are integers and b ≠ 0" because it poses some problems. For instance 22/7 fulfills this condition but it is not a rational number! So it is best defined the way I just defined it.
An irrational number is a number that does not have terminating and recurring decimal, like 3.565215805.....
Integers are real numbers that are whole numbers.
Looking at the situation, which is the money in a bank account. The value will be a number that is rational because it is always an exact amount and this implies that it will always be a terminating decimal. Note that 45.00 is also a terminating decimal.
A vertical parabola goes through (1,-2), (-3, 10), and (4, 31). Use matrices to
solve for D, E, and F, given the general form x² + y2 + Dc + Ey + F = 0 (since it
is a vertical parabola there is not a z term).

Answer:
D = 1/2 , E = -1/2 , F = -5/2
Step-by-step explanation:
vertical parabola : ( 1,-2), ( -3, 10 ), (4, 31 )
General form ; [tex]x^2 + y^2 + Dx + Ey + F = 0[/tex]
( 1 ,-2 ) = x1, y1
( -3, 10 ) = x2, y2
( 4, 31 ) = x3, y3
hence :
[tex]y1 = ax_{1} ^2 + bx_{1} + c[/tex]
[tex]y2 = ax_{2} ^2 + bx_{2} + c[/tex]
[tex]y3 = ax_{3} ^2 + bx_{3} + c[/tex]
attached below is the detailed solution required
D = 1/2 , E = -1/2 , F = -5/2

A baker sells bread for $4 a loaf and rolls for $1 each. The baker needs to sell $36 worth of baked goods by
the end of the day.
Enter a linear equation that describes the problem.
An equation for the value of the baked goods is
bread sold, and r is the number of rolls sold.
= $36, where b is the number of loaves of
Explanation:
Cost of 1 loaf of bread = $4
Cost of 1 roll = $1
The baker needs to sell both items and it should be worth $36.
To find the linear equation, Suppose, the baker sells "b" loaves of bread and "r" rolls.
Then the total cost of the sales has to be $36.
So, the linear equation will be:
4b + 1r = 36

ABC is an isosceles triangle.
• AB = AC = 11 cm
E
. E and F are the midpoints of AB
and AC respectively,
• EF is parallel to BC.
55
B
Find the area of the trapezium BEFC.
Answer: 90,75. cos 55°. sin55° ≈ 42,64
through E, draw EK perpendicular to BC (F ∈ BC)
because E is the midpoint of AB => BE = 11/2 = 5.5
ΔBEF is a right triangle at K
=> sin 55° = EK/BE
=> EK = 5,5.sin 55°
ΔABC has E and F is the midpoints of AB and AC
=> EF is the median line of the triangle
=> EF = 1/2.BC
through A, draw AD perpendicular to BC
=> ΔABD is a right triangle at D
=> BC = 11.cos 55°.2 = 22.cos 55°
=> EF = 11.cos 55°
=>the area of the trapezium BEFC is:
[tex]\frac{5,5.sin55(11.cos55+22.cos55)}{2}=90,75.cos55.sin55[/tex]

9514 1404 393
Answer:
rigidnon-rigidnon-rigidrigidStep-by-step explanation:
The transformations of 1 and 4 are translations (1 and 4) and reflection (4), so are rigid transformations.
The transformation of 3 is a dilation by a factor of 3, so is non-rigid.
The transformation of 2 is a horizontal stretch by a factor of 2 and a vertical stretch by a factor of 3. It, too, is a non-rigid transformation, but is not strictly dilation.

Answer:
Ok so we see that at the end there is a +2 so the first thing we want to do is start our first point at (0,2). After that we can see that our slope is -1/2, since slope equals x/y we know that it is asking us to go 1 to the right, however since it is negative we will be going 2 down. the Y intercept is the point where the line intercepts the Y-axis which is (0,2)
Step-by-step explanation:
Answer:
slope= -1/2
y-intercept = (0,2)
Step-by-step explanation:
The y-intercept is what y equals when x equals zero. On the graph, it is where the graph crosses through the y axis.
To find the y-intercept, plug in 0 for x, so x = 0
y = -1/2 (0) + 2
y=2
and we know x =0
So the point is (0,2)

Lila rode her bike from 9:30 am to 11:10 am this morning. She rode 1.5 miles every 10 minutes. What is the total number of miles Lila rode this morning?
Answer:
15mi
Step-by-step explanation:
9:30am to 11:10am equals 100 minutes
100 minutes divided by 10 minutes per segment equals 10 segments
1.5 miles per segment multiplied by 10 segments equals 15 total miles
Grandma’s Garden has an area of 95 square feet. The. Length of one side of her garden would be between what two whole numbers? What is the length of this side to the nearest tenth of a foot? Represent this number on a number line as a square root and a decimal.
Answer:
Between 9 and 10
Step-by-step explanation:
Area = 95 square feet
The garden is a square
[tex]a^2 = 95[/tex]
a = [tex]\sqrt{95}[/tex] = 9.75
The two whole numbers for side length is between 9 and 10.
The length of this side to the nearest tenth of a foot is 9.8ft.
