Answer:
The card was worth $160.
Step-by-step explanation:
It is given that:
Percent of gift card used = 42%
Cost of groceries = $67.20
Let,
x be the total amount on gift card.
42% of x = 67.20
[tex]\frac{42}{100}x=67.20[/tex]
0.42x = 67.20
[tex]\frac{0.42x}{0.42}=\frac{67.20}{0.42}\\x=160[/tex]
Therefore,
The card was worth $160.

If 1.) Gabby made a scale drawing of the Sam Houston statue in Huntsville, TX. The statue is actually 67 feet tall. Gabby's model used a scale of 1 inch = 20 feet. What was the length of her drawing?
Answer:
3.35 inches
Step-by-step explanation:
Actual height of statue = 67 feets
Scale used : 1 inch = 20 feets
Let Length of drawing = x
1 inch = 20 feets
x inch = 67 feets
Cross multiply to obtain the length of the drawing in inches
20 * x = 67 * 1
20x = 67
x = 67 / 20
x = 3.35 inches
Hence, length of her drawing is 3. 35 inches

Augie has hit the baseball 75% of the time this year. How many times will he hit the ball if
he bats a total of 32 times?
I’m need some help please! :(
Answer:
24 times
Step-by-step explanation:
75% = 0.75, so then you just do 0.75 * 32 = 24
Answer:
For this question, multiply 75% or 0.75 with 32. The result would be 24. So, Augie has hit the baseball 24 times.

What is the probability of picking a 5 and then picking an even number?
Answer:
1/10 or 10%Step-by-step explanation:
Probability = favorable outcome / total number of outcomes
p(5) = 1/65 numbers left and 3 of them are even.
p(even) = 3/5So combined probability is:
p(5 and even) = 1/6*3/5 = 1/10I need yo solve y on this problem. 16x+9y-2x
Answer:
14x+9y
Step-by-step explanation:
Combine Like terms. 16x-2x=14x
dont forget the 9y
so 14x+9y
Mark wants to find the area of a circle with a diameter of 6 cm. Which expressions can he use to find the area of the circle in square centimeters? Choose all the correct answers.
a.3^2*pi
b.6*pi
c.2*3*pi
d.3*3*pi
e.6*pi
Answer:
B and C
(I'm not sure if b and e are supposed to be the same though) if they are then, b, c, and e
Answer:
The correct options are Option A and Option D
Step-by-step explanation:
Mark wants to find the area of a circle with a diameter of 6 cm.
We need to find the expressions can he use to find the area of the circle in square centimetres?
The formula used to find area of circle is: [tex]Area=\pi \:r^2[/tex]
We are given Diameter = 6 cm
Radius = Diameter/2 = 6/2 = 3 cm
We get radius = 3cm
Now, putting values and finding area
[tex]Area=\pi \:r^2\\Area=\pi \:(3)^2\\Area=3^2\:\pi[/tex]
We can also write it as:
[tex]Area=3*3*\:\pi[/tex]
So, correct options are Option A and Option D
How do I find the volume of a prism?
Answer:
470 cm³
Step-by-step explanation:
Decompose the prism into two rectangular prism.
Prism 1 will have the following dimensions and volume:
Length = 10 cm
Height = 8 cm
Width = 9 - 5 = 4 cm
Volume = L × W × H
Volume = 10 × 8 × 4 = 320 cm³
Prism 2:
Length = 10 cm
Height = 3 cm
Width = 5 cm
Volume = 10 × 3 × 5 = 150 cm³
✔️Volume of the entire prism = 320 + 150 = 470 cm³
Ifp * (x) = 3x ^ 2 - 4 and r(x) = 2x ^ 2 - 5x + 1 . find value r(x + 2)
Answer:
r(x+2) = 2x² + 3x - 1Step-by-step explanation:
[tex]r(x) = 2x ^ 2 - 5x +1\\\\ r(x+2) = 2(x+2)^ 2 - 5(x+2) +1\\\\ r(x+2) = 2(x^2+4x+4) - 5x-10+1\\\\ r(x+2) = 2x^2+8x+8 - 5x-9\\\\ r(x+2) = 2x^2+3x-1[/tex]

A new car is purchased for 19000 dollars. The value of the car depreciates at 11.25% per year. What will the value of the car be, to the nearest cent, after 14 years.
Answer:
$3573. 64
Step-by-step explanation:
Convert 11.25% to the decimal fraction 0.1125. Then subtract this result from 1.0000: 0.8875.
After 14 years, the formerly $19000 car will have the value
$19000(0.8875)^14 = $3573. 64
Mercury is the closest planet to the sun at a distance of 36 million miles. The closest star to the sun is Proxima Centauri, which is 4.24 light years away. A light year is 5.9 x 10 to the 12th power. How many miles from the sun is Proxima Centauri?
Answer:
2.36 * 10^13 miles
Step-by-step explanation:
Given that :
Proxima centauri is at a distance of 4.24 light years away from the sun.
Distance in miles of Proxima centauri from the sun ;
1 light year = 5.9 * 10^12 miles
Number of light years from the sun * 5.9 * 10^12
= 4 * (5.9 * 10^12)
= 23.6 * 10^12 miles
= 2.36 * 10^13 miles

Step-by-step explanation:
Maria wants to know if the number of words on a page in her earth science book is generally more than the number of words on a page in her math book. She takes a random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.
Mean Median Mean Absolute Deviation
Earth science 48.9 41 9.2
Math 34.5 44 1.9
She claims that because the mean number of words on each page in the earth science book is greater than the mean number of words on each page in the math book, the earth science book has more words per page. Based on the data, is this a valid inference?
Answer:
No, because there is a lot of variability in the earth science book data.
Step-by-step explanation:
I just took the test and the explanation is that the earth book has more pages and more variability so that is why her answer is wrong.
Answer:
No, because there is a lot of variability in the earth science book data.

4/5p - 3/5p - 4 = 0
And I need to write out my work
9514 1404 393
Answer:
p = 20
Step-by-step explanation:
Collecting terms gives ...
(4/5 -3/5)p - 4 = 0
1/5p - 4 = 0
Multiplying by 5, we get ...
p - 20 = 0
Then, adding 20 gives the solution:
p = 20
