Johnny had a math test and he started at 2:18 p.M. It took 75 minutes to complete the test. He had a dentist's appointment at 4:30 p.M. How much time, in minutes, did he have between the end of the test and his appointment time
Answer:
57 minutes
Step-by-step explanation:
First, add 75 minutes to the time he started the test. Then, subtract the time you get from the time for his dentist appointment.
75 minutes is the same as 1 hour 15 minutes (1 hour = 60 minutes)
H M
2 : 18
+ 1 : 15
3 : 33
He ended the test by 3:33 PM.
H M
4 : 30
- 3 : 33
0 : 57
Therefore, he had 57 minutes between the end of the test and his appointment.
Find the volume of a right circular cone that has a height of 10.7 in and a base with a diameter of 8.1 in. Round your answer to the nearest tenth of a cubic inch.
Answer:
[tex] V = \pi r^2 h[/tex]
And for this case the value for the height is [tex] h = 10.7 in[/tex] the diameter is provided [tex] D = 2r = 8.1 in[/tex] so then the radius is given by:
[tex] r = \frac{D}{2}=\frac{8.1 in}{2}= 4.05 in[/tex]
Then we can find the volume with the first formula and replacing we got:
[tex] V = \pi (4.05in)^2 (10.7 in)= 551.4 in ^3[/tex]
The final answer for this case would be 551.4 cubic inches
Step-by-step explanation:
The volume for a right circular cone is given by this formula:
[tex] V = \pi r^2 h[/tex]

Natalie has $250 in savings. At the end of 6 months, she has $450 in savings. What is the percent increase in the amount of her savings?
80 percent. 80 percent of 250 is 200 and 250 increased by a total of 200 therefore 80%
Answer: 80%
Step-by-step explanation:
Rule of 3.
Let's put the money on the left side and the percents on the right side.
[tex]\frac{250}{450}=\frac{100}{x}[/tex]
Solve for x:
[tex]x=\frac{450*100}{250}[/tex]
[tex]x=180[/tex]
Subtract 100 from 180
180-100=80
3. You want to standardize a new recipe for Chicken Alfredo. The old recipe that you have been using yields 40 servings and you would like the new yield to be 150 servings. What is the conversion factor? Use the conversion factor to determine how much chicken is needed, if the old recipe called for 8 pounds. Show your work
If the original receipe requires 8 pounds and yields 40 serving, and we need to up it to 150:
40/150=8/x
Cross multiply:
40x=150x8
40x= 1200
X= 30 pounds of chicken
Which is the same as diving a number by 10?
Answer:
Step-by-step explanation:
well i guess if the decimal is on the left you would move it to the right twice
because if you only moved it once it'd become 1.0
and if you moved it to the left once it would also become 1.0
and if you moved it twice to the left you would be left with .10

Cross multiplication method, find the value z and y for 3x + 5y = 70 and 7x-3y =60
Answer:
Y=7.05
X= 11.6
Step-by-step explanation:
Equate both equations to zero
3x+5y=70--------equation 1
7x-3y=60---------equation 2
From the equation above
a1=3, b1=5, c1=-70
a2=7, b2= -3, c2=-60
By applying the cross multiplication method
x/b1c2-b2c1= y/a2c1-a1c2= 1/a1b2-a2b1
x/(5)(-60)-(-3)(-70)=y/(7)(-70)-(3)(-60)=1/(3)(-3)-(7)(5)
x/-300-(-210)=y/-490-(-180)=1/-9(-35)
x/-510=y/-310=1/-44
x/-510=1/-44 , y/-310=1/-44
-44x=-510 , -44y= -310
x=11.6 , y=7.05
Thus, the value of x is 11.6 and the value of y is 7.05

Find the area of a triangle with a =4, b =6, and c =8.
a. 10.2 units 2
b. 8.4 units 2
C.12.4 units
d. 11.6 units 2
Answer:
d
Step-by-step explanation:
Given 3 sides of the triangle the area (A) can be calculated using Hero's formula.
A = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
where s is the semi perimeter of the triangle
s = [tex]\frac{a+b+c}{2}[/tex] = [tex]\frac{4+6+8}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9 , thus
A = [tex]\sqrt{9(9-4)(9-6)(9-8)}[/tex]
= [tex]\sqrt{9(5)(3)(1)}[/tex]
= [tex]\sqrt{135}[/tex]

3. WEDNESDAY (5/20): The minimum of the graph of a quadratic function is located at (-1,2). The point (2, 2015
also on the parabola. Which function represents this?
a) f(x) = x² + 2x + 3
b) f(x)= x² - 2x+3
c) f(x) = 2x²+4x+4
d) f(x)= 2x²- 4x+4
Answer:
C.) f(x) = 2x^2 + 4x + 4
Step-by-step explanation:
The equation of the parabola with vertex (h,k) is y=a(−h+x)^2+k.
Thus, the equation of the parabola is y=a(x+1)^2+2.
To find a, use the fact that the parabola passes through the point (2,20): 20=9a+2.
Solving this equation, we get that a=2.
Thus, the equation of the parabola is y=2(x+1)^2+2.
TO STANDARD FORM
= 2*(x^2+2x+1)+2
=(2x^2+4x+2)+2
= 2x^2+4x+2+2
= 2x^2+4x+4

Answer:
1/24
Step-by-step explanation:
i just took it
The probability that the sequence is guessed on the first try is 1/24.
ProbabilityTotal colors available for making code=4
Colors required for making code=3
Hence:
Total ways of making code=4p3=4!/(4-3)!
=4×3×2×1/1

Probability that the sequence is guessed on the first try=1/Total ways of making code
Probability that the sequence is guessed on the first try=1/24
Therefore the correct option is A.

6-129. Nick represented the equation 3(2x+4)=-6 on the Equation Mat below. Choose a strategy to solve for x. You may continue to use algebra tiles, or you may use symbols on paper.
Answer:
x = -3
Step-by-step explanation:
You have the following equation:
[tex]3(2x+4)=-6\\[/tex]
you first you distribution property in order to eliminate the parenthesis:
[tex]3*2x+3*4=-6\\\\6x+12=-6[/tex]
next, you subtract 12 in both sides of the equation:
[tex]6x+12-12=-6-12\\\\6x=-18[/tex]
Finally, you divide the equation by 6 and simplify:
[tex]\frac{6x}{6}=-\frac{18}{6}\\\\x=-3[/tex]
hence, the solution to the equation is x = -3
An angle measures 39.2° less than the measure of its complementary angle. What is the measure of each angle?
Answer: The measures of the angles are 64.6 degrees and 25.4 degrees.
Step-by-step explanation:
Complementary angles add up to 90 degrees.
x can be one angle, and (x-39.2) can be the other
x + (x-39.2) = 90
2x - 39.2 = 90
add 39.2 to both sides
2x = 129.2
divide each side by 2
x = 64.6
find the measure of the other angle
64.6-39.2 = 25.4
The measures of the angles are 64.6 degrees and 25.4 degrees.
Answer:
25.4 and 64.6Step-by-step explanation:
Suppose two complementary angles of measures x And y then
x + y = 90 and y = x - 39.2
if we plug in x - 39.2 instead of y in the equation x + y = 90 we get :
x + (x - 39.2) = 90
then
2x = 90 + 39.2
then
2x = 129.2
then
x = 129.2/2 = 64.6
therefore
y = 64.6 - 39.2
= 25.4
