At Safeway, a pound of apples cost $1.32. Mrs. Terry purchased 7.5 pounds of apples. How much money did
Mrs. Terry spend on apples?
Answer:
the answer is $1.32×7.5=$9.9
Answer:
£9.90
Step-by-step explanation:
There are 2 ways you can do this. Both are similar.
For the first method it's much quicker but you might need a calculator.
You would simply do 7.5 × 1.32 = £9.90 that should give you the answer.
If you were to do it with out a calculator then what you need to do is 7 × 1.32 = 9.24
Because there is still 0.5 (or 1/2) left from the 7 that you multiplied, you do 1.32 ÷ 2 = 0.66.
Add the 2 numbers together
0.66 + 9.24 = £9.90
a right triangle whose acute angles have measures 5x and 4x.
Answer:
x=10
50 and 40
Step-by-step explanation:
The sum of the angles of triangle is 180
90 +5x+4x = 180
Combine like terms
90 +9x =180
Subtract 90 from each side
9x = 180-90
9x = 90
x = 90/9
x = 10
The angles are 5x = 5*10 =50 and 4x = 4(10)= 40
What is the volume of the following rectangular prism?
Answer:
14 2/3 units^3
hope this helps
have a good day :)
Step-by-step explanation:
7 1/3 x 2=14 2/3
The volume of the rectangular prism is 14.66 square units.
It is required to find the volume of the rectangular prism.
What is prism?Prism is a three-dimensional solid object in which the two ends are identical. It is the combination of the flat faces, identical bases and equal cross-sections. The faces of the prism are parallelograms or rectangles without the bases.
Given:
The volume is calculated as:
V= w h l
V= 7 1/3 x 2
V= 22/3 x 2
V= 44/3
V=14.66 square units.
Hence, the volume of the rectangular prism is 14.66 square units.

John finds that there is a scholarship available to all personals scoring in the top 5% on the ACT test. If the mean score on the ACT is 21 with a standard deviation of 4.7, what score does he need in order to qualify for the scholarship
Answer:
He needs a score of 28.7315 to qualify for the scholarship
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The mean score on the ACT is 21 with a standard deviation of 4.7
This means that [tex]\mu = 21, \sigma = 4.7[/tex]
What score does he need in order to qualify for the scholarship?
The top 5%, so the 100 - 5 = 95th percentile, which is X when Z has a p-value of 0.95, so X when Z = 1.645.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.645 = \frac{X - 21}{4.7}[/tex]
[tex]X - 21 = 4.7*1.645[/tex]
[tex]X = 28.7315[/tex]
He needs a score of 28.7315 to qualify for the scholarship

round to the nearest tenth for 69.08, 43.96, 39.564 please show how to do it
Answer:
69.08 ⇒ nearest tenth
To round 69.08 to the nearest tenth, 0 is in the tenths place and 8 is in the hundredths place. Since the digit in the hundredths place (8) is greater than 5, add 1 to the digit in the tenths place (0).
1 + 0 = 1, so the digit in the tenths place becomes 1 & the digit in the hundredths place is dropped.
∴ 69.08 ≈ 69.1 (corrected to the nearest tenth)
43.96 ⇒ nearest tenth
To round 43.96 to the nearest tenth, 9 is in the tenths place and 6 is in the hundredths place. Since the digit in the hundredths place (6) is more than 5, add 1 to the digit in the tenths place (9), add 1 to the digit in the tenths place (9). This will also add 1 to the whole number part and make the fractional part 0.
1 + 9 = 10
∴ 43.96 ≈ 44 (corrected to the nearest tenth)
39.564 ⇒ nearest tenth
To round 39.564 to the nearest tenth, 5 is in the tenths place and 6 is in the hundredths place. Since the digit in the hundredths place (6) is more than 5, add 1 to the digit in the tenths place (5), add 1 to the digit in the tenths place (5).
1 + 5 = 6, so the digit in the tenths place becomes 6 & the digit in the hundredths and thousandths place is dropped.
∴ 39.564 ≈ 39.6 (corrected to the nearest tenth)
Rounding to the nearest tenth are:
69.08 rounded to the nearest tenth is 69.1.43.96 rounded to the nearest tenth is 44.0.39.564 rounded to the nearest tenth is 39.6.Rounding to the nearest tenth means finding the nearest multiple of 0.1 or one decimal place.
To do this, examine the digit in the hundredth place and decide whether to round up or down based on that digit.
For 69.08, the digit in the hundredth place is 0.
Since 0 is less than 5 then round down, which means the digit in the tenths place remains the same.
Thus, 69.08 rounded to the nearest tenth is 69.1.
For 43.96, the digit in the hundredth place is 9.
Since 9 is greater than or equal to 5, increasing the digit in the tenths place by 1.
Therefore, 43.96 rounded to the nearest tenth is 44.0.
For 39.564, the digit in the hundredth place is 5.
Since 5 is exactly halfway between 0 and 10, round to the nearest even number.
Thus, 39.564 rounded to the nearest tenth is 39.6.

An isosceles triangle always has three interior angles that measure 60° each.
Is it true or false?
Please give real answers with explanation. 100 points + I will give brainliest. No Docs/No Files/No Links only answer with explanation.
Answer:
False
Step-by-step explanation:
The definition given is that of an equilateral triangle, NOT that of an isosceles triangle. An isosceles triangle has at least two angles that are equal by definiton. They need not be 60 degrees. For example, a triangle with angle measures of 140, 20, and 20 is an isosceles triangle because two of the angles are equal. Hope this helped!
Find the value of p when 3P = 1/9
Answer:
p=1/27
Step-by-step explanation:
3p=1/9
when 9 goes to the left land side divide changes into multiplication so 3p and 9 gets multiplied
3p*9=1
27p=1
when 27 goes the right hand side multiplication changes to division .So
p=1/27
The value of P is 1/27 for equation 3P = 1/9
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Equation is 3P = 1/9
Three times of P equal to one by nine
We need to find the value of P
3P = 1/9
Divide both sides by nine
3P/3=1/9×1/3

The art club held a car wash on Saturday and Sunday. They washed a total of 50 cars. If they washed 30% of the cars on Sunday, how many cars did they wash on Sunday?
Answer:
If I did my math correctly, They washed 15 cars on Sunday.
Step-by-step explanation:
50 cars = 100%
Therefore 1 car would be 2% because 50 is half of 100.
So because 30% would be 2 times the amount of cars, we divide 30 by 2, giving us 30% = 15 cars on Sunday
With this information, we can take away 15 from 50 giving us 35 cars which is equal to 70% on Saturday
Here is some extra data:
10% = 5 cars
20% = 10 cars
30% = 15 cars
40% = 20 cars
50% = 25 cars
60% = 30 cars
70% = 35 cars
80% = 40 cars
90% = 45 cars
100% = 50%
Basically, every 10% is +5 cars
Mrs Roberts makes 'regular' and 'low-sugar' jam.
She sells both kinds of jam in 340-gram jars.
55% of the weight of her 'regular' jam is sugar.
What weight of sugar is there in a 340-gram jar?
Answer:
187 gram
Step-by-step explanation:
Regular jam = low sugar jam = 340-gram jars
55% of the weight of her 'regular' jam is sugar.
What weight of sugar is there in a 340-gram jar?
Weight of sugar in a 340-gram jar of regular jam = 55% of 340
= 55/100 × 340
= 0.55 × 340
= 187
Weight of sugar in a 340-gram jar of regular jam = 187 gram

A metal washer has an outer diameter of 14mm and an inner diameter of 6mm.Use the value of 3.14 for the to find the area of the metal washer
Answer:
502.4 mm^2
Step-by-step explanation:
First find the area of the larger circle, and then that of the smaller one.
Then subtract the latter (2nd) area from the first.
larger circle area smaller circle area
------------------------- ---------------------------
3.14(14 mm)^2 3.14(6 mm)^ 2
This comes out to 3.14[14^2 - 6^2] mm^ 2 = 3.14[196 - 36] mm^2, or
3.14(160 mm^2) = 502.4 mm^2
The area of the metal washer is 502.4 mm^2.
