Answer:
36
Step-by-step explanation:
If it is two hours then half of it is 9
18+9= 27 that's how many miles she bikes
6 is the number of miles she ran
So add them to get the total: 27+9= 36 hours
Solve for x. Please look at the picture and answer it. Thank you.
Answer:
ans = 9 degree
Step-by-step explanation:
81 + (4x) + (5x+18) = 180 (The sum of all angles of triangle is 180 degree)
81 + 4x + 5x + 18 = 180
99 + 9x = 180
9x = 180 - 99
9x = 81
x = [tex]\frac{81}{9}[/tex]
x = 9 degree

Miranda wants to use a 15% off coupon on her $120 purchase at Macys.com. She is trying to
figure out how much she will save.
Which equation is the correct way to determine the accurate amount?
120 - 15% = x
120 - 15% = x
120 + 15% = x
120 + 15% = x
Question 16
2 pts
Answer:
120 - 15% × 120 = x
Step-by-step explanation:
All given answers are incorrect.
15% means 0.15
She is not subtracting 15% or 0.15 from 120.
She is subtracting 15% of 120 from 120.
The correct answer is
120 - 15% × 120 = x

find the circumference and the area of a circle with diameter of 6 ft
use 3.14
Answer:
Step-by-step explanation:he equation for circumference is:
c=2%28pi%29r
The equation for area is:
a=%28pi%29r%5E2
First, we'll find the circumference.
The 'r' in the equation stands for radius. The radius of a circle is half of its diameter, so the circle's radius is half of 6--3 inches.
So, we can substitute 3 in for 'r' and 3.14 in for pi
c=2%28pi%29r
c=2%2A3.14%2A3
Then, we can simply multiply.
c=2%2A3.14%2A3
c=18.84
Therefore, the circumference of the circle is 18.84
Next, we'll find the circle's area.
Again, we can substitute 3 in for 'r' and 3.14 in for pi
a=%28pi%29r%5E2
a=3.14%2A3%5E2
The, we'll square three and multiply.
a=3.14%2A3%5E2
a=3.14%2A9
a=28.26
Therefore, the circumference is 18.84 and the area is 28.26.
Solve the equation algebraically.
2lnx + 7 = ln(4x) + 10
Round your final answers to two decimal places.
Answer:
x = 80.34 (2 dp)
Step-by-step explanation:
[tex]2\ln(x)+7=\ln(4x)+10[/tex]
[tex]\implies \ln(x^2)+7=\ln(4x)+10[/tex]
[tex]\implies \ln(x^2)-\ln(4x)=10-7[/tex]
[tex]\implies \ln\left(\dfrac{x^2}{4x}\right)=3[/tex]
[tex]\implies \ln\left(\dfrac{x}{4}\right)=3[/tex]
[tex]\implies e^{\ln\left(\dfrac{x}{4}\right)}=e^3[/tex]
[tex]\implies \dfrac{x}{4}=e^3[/tex]
[tex]\implies x=4e^3[/tex]
[tex]\implies x=80.34 \textsf{ (2 dp)}[/tex]

1. Create a grid that is 5 squares wide by 2 squares tall. Shade 8 squares as shown above.
A. Look at the shaded:total in the gizmo table. What decimal and percent are modeled by the shaded squares?
Decimal: 0.8Percent: 80%Decimal part =
10 squares
8 shaded
0.2=2 squares shaded
so
8 squares shaded = 0.8
Percent part =
if 100% = 1 whole
1 whole = 10 blocks in gizmo table
then
8 blocks in gizmo table = 80%
since
1 block = 10%
10%x8=80
80%
B. Look at the unshaded:total row. What decimal and percent by the unshaded squares?
Decimal: 0.2Percent: 20%Decimal part:
If there are 2 unshaded squares
and we know that 1 square = 0.1
then, 2 squares = 0.2
0.2
Percent part:
if we know that 10 blocks = 1 whole
and 1 block = 10%
then 2x10%=20%
20%
1. The Gizmo gives two equivalent (equal) fractions — simplified and unsimplified — for the shaded:total and unshaded:total ratios. Record them below. (to see why these are equivalent, notice how many shaded and unshaded squares are in each row of the grid.)
[tex]\frac{shaded}{total}=\frac{8}{10}=\frac{4}{5}[/tex] [tex]\frac{unshaded}{total} =\frac{2}{10} =\frac{1}{5}[/tex]
Thanks!

Answer:
Decimal : 0.8
percent: 80%
decimal: 0.2
percent: 20%
shaded/total = 8/10 = 4/5
unshaded/total = 2/10 = 1/5

an 8in by 12in picture has a frame of uniform width around it the area of the frame is equal to the area of the picture. what is the width of the frame
Answer:
2 inches
Step-by-step explanation:
The area of the frame will be the difference between the area of the picture with frame, and the area of the picture without. We want that difference to be equal to the area of the picture without the frame.
Let x represent the width of the frame. The overall length and width of the picture will be increased by 2x when the frame is added. Then we have ...
a = LW = (8+2x)(12+2x) . . . . area of picture and frame
b = LW = (8)(12) . . . . . . . . . . area of picture
a -b = b . . . . . . desired relationship between areas
Substituting and expanding the expressions for 'a' and 'b', we find ...
a -2b = 0 . . . . subtract b
(8 +2x)(12 +2x) -2(8)(12) = 0
4x² +40x -96 = 0 . . . simplify
x² +10x -24 = 0 . . . . . divide by 4
(x -2)(x +12) = 0 . . . . factor
The positive value of x that makes this true is x = 2.
The width of the frame is 2 inches.

(2x+6)(x-4)
Answer:
4 and -3
Step-by-step explanation:
2x+6=0
2x=-6
-3
x-4=0
x=4
So its 4 and -3
Answer:
-3,4
Step-by-step explanation:
(2x+6)(x-4) = 0
Using the Zero Factor Principle: If ab =0 then a=0 or b=0
2x+6=0 or X-4=0
solve 2x+6=0:
2x+6=0
Subtract 6 from both sides
2x+6-6 0-6
Simplify
2x = -6
Divide both sides by 2
2x/2 = -6/2
Simplify
X=-3
then x-4 =0
add 4 from to both sides
x=4
zeros : -3,4

Answer:
x = 1
explanation:
[tex]\sf \rightarrow \dfrac{3}{x} -1 = 2[/tex]
[tex]\sf \rightarrow \dfrac{3}{x} = 2+1[/tex]
[tex]\sf \rightarrow \dfrac{3}{x} = 3[/tex]
[tex]\sf \rightarrow {3} = 3(x)[/tex]
[tex]\sf \rightarrow \dfrac{3}{3} = (x)[/tex]
[tex]\sf \rightarrow x = 1[/tex]
checking if x = 1,
[tex]\sf \rightarrow \dfrac{3}{1} -1 = 2[/tex]
[tex]\sf \rightarrow3 -1 = 2[/tex]
[tex]\sf \rightarrow 2 = 2[/tex]
→ Hence proved x : 1 as L.H.S = R.H.S
Step-by-step explanation:
[tex] \frac{3}{x} - 1 = 2 \\ [/tex]
Adding 1 on both sides, we get[tex] \frac{3}{x} - 1 + 1 = 2 + 1 \\ \frac{3}{x} = 3[/tex]
By performing cross multiplication, we get[tex]3 \times x = 3 \times 1 \\ 3x = 3[/tex]
Dividing both sides by 3, we get
[tex] \frac{3x}{3} = \frac{3}{3} \\ x = 1[/tex]
Hence, the value of x is 1.WILL GET MARKED BRAINLIEST IF RIGHT! ( please look at picture )
Jewel spins the pointer of a spinner. The spinner has 7 equal-sized sections labeled 1 to 7. What is the probability that Jewel will spin a 7?
Answer:
14
Step-by-step explanation:
It's a probability, divide favorable outcomes to total outcomes
Answer:
14%
Step-by-step explanation:
There are 7 sections of equal size.
The total number of possible outcomes is 7.
There is one single outcome that is desired, landing on 7.
probability of an event = (number of desired outcomes)/(total number of possible outcomes)
p(7) = 1/7 = 0.142857... = 14%

Answer:
1. 0.8165 ; 2. 27.52 ; 3 = 3.8352 ; 4. 812.128 ; 5. 11.8513
Step-by-step explanation:
1. 3 - 2.1835 = 0.8165
2. 38.35 - (3.9 + 6.93) = 27.52
3. 8 - 4.1648 = 3.8352
4. 604 + 406.064 = 1010.064
604 - 406.064 = 197.936
1010.064 - 197.936 = 812.128
5. 18.35 - 6.4987 = 11.8513
