y=4×35 =140 (guests)
Anita found a 16-ounce jar of pickles that costs $4.80. She wants to buy the 24-ounce jar, but the price is not listed. If the unit price is the same for both sizes, how much does the 24-ounce jar of pickles cost?
Answer:
$7.20
Step-by-step explanation:
16/4.80 = 24/?
Answer:
7.20
Step-by-step explanation:
First find what one oz. costs. To do this, divide 4.80 from 16. This is 3 rounded. Multiply 3 by 24. This is 72. Move the decimal to the left once, to get 7.20.

what is the midpoint of BD
Answer:
I don't know what your numbers are, but if it is on a number line, just add the absolute values (always positive) of the endpoints together, and divide by 2 (find the average).
On a graph, find the average of the x coordinates, (that is midpoint x value) and the average of the y coordinates (that is midpoint y value)
Step-by-step explanation:
If you have a negative number, the absolute value is the same number, just positive. E.X. -4 the absolute value is 4.

Roger has $5000 more invested at 7 1/4% then he has at 6%. If his total profit at the end of the year $659.30, how much has he invested at each rate?
Answer:
You have the number of nickels and the number of quarters both expressed in terms of the number of dimes. So let your variable be the number of dimes. Call this D. Then the number of nickels is 4D, and the number of quarters is D+6. The total value is
0.10(D) + 0.05(4D) + 0.25(D+6) = 4.25
Solve this for D, and use D to find 4D and D+6.

Meg walks to school and work each day and wants to track how far she walks each day. In the morning, Meg walks 7 blocks due east to school. After school, she walks 2 blocks north and then 4 blocks west to reach work. She walks straight home from work. How far does she walk in all? Enter the correct number in the box. Round to the nearest tenth.
Answer:
I am pretty sure it is 19 blocks because it is 14 blocks before going back home. She needs to walk 3 blocks west and 2 blocks south. 14+3+2=19

Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stops to see how much farther he has to go. If Yan made 8 stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan climbed?
4 + 4 + 4 + 4
8 + 8 + 8 + 8
(Negative 1) (4 + 4 + 4 + 4)
(Negative 8) + (negative 8) + (negative 8) + (negative 8)
Answer:
8+8+8+8
Step-by-step explanation:
it can't be any negatives because the questions asking how many ladder rungs he climed not how far he went down. It can't be the first one cause Yan did not climb 16 rungs.

find the value of x in log^x base 9=3÷2
Answer:
x = 27.
Step-by-step explanation:
log9 x = 3/2
By the definition of a log:
9^3/2 = x
x = (√(9)^3)
x = 3^3
x = 27.
A Table showing Freezing Temperatures in degrees with 2 columns and 6 rows. The First row, F, has the entries, negative 13, negative 4, 5, 14, 23. The second column, C, has the entries, negative 25, negative 20, negative 15, negative 10, negative 5. The table shows temperatures below freezing measured in different units. Complete the equation in standard form to represent the relationship between F, a temperature measured in degrees Fahrenheit, and C, a temperature measured in degrees Celsius. 5F + C = 39°F = °C rounded to the nearest tenth of a degree
Answer:
5F + -9 C= 160 39°F = 3.9
Step-by-step explanation:
A Table showing Freezing Temperatures in degrees with 2 columns and 6 rows. The First row, F, has the entries, negative 13, negative 4, 5, 14, 23. The second column, C, has the entries, negative 25, negative 20, negative 15, negative 10, negative 5.
The table shows temperatures below freezing measured in different units. Complete the equation in standard form to represent the relationship between F, a temperature measured in degrees Fahrenheit, and C, a temperature measured in degrees Celsius.
5F + -9 C = 160
39°F = 3.9°C rounded to the nearest tenth of a degree
The co-relationship between temperatures measured in Fahrenheit F, and in Celsius C is shown using an equation.
The equation is: 5F = 9C + 160The temperature in degrees Celsius when temperature in degrees Fahrenheit is 39, is 3.9What is an equation?
The equation is an expression that highlights the co-relationship between two or more variables.
Let F represent temperature measured in degrees Fahrenheit, and C, a temperature measured in degrees Celsius.
At 0°C, the temperature is 32°F. Also at 100°C, the temperature is 212°F, hence:
C = (5/9)(F - 32)
First, calculating the slope (m) :
From the table we have:
m = (C₂-C₁)/(F₂-F₁)
m = (-20-(-25))/(-4-(-13))
m = 5/9
The equation is now calculated :
C = m(F-F₁) + C₁
C = 5/9 (F + 13) - 25
5F = 9C + 160
For value of C for F= 39 , we have,
C = 5/9 (F + 13) - 25
C = 5/9 (39+13) - 25
C = 3.9
Therefore, the value of C is 3.9.

1. Samuel made a 76% on his Algebra test. He got 22 questions correct. How many total questions
were on his Algebra test?
HELP PLEASE✨
Answer:
29 questions on his test
Step-by-step explanation:
set it up as fractions equal to each other so that you can solve for x
[tex]76\%= \frac{76}{100}[/tex]
x is the total number of questions on the test
we know that samuel got 22 of those questions correct, and a grade is calculated by dividing the number of correct answers by the total number of questions, so we can write
[tex]\frac{76}{100}=\frac{22}{x}[/tex]
then you can solve by cross multiplying
[tex]76x = 22 (100)[/tex]
[tex]76x=2200[/tex]
get the x by itself by dividing both sides by 76, and then you have x
[tex]\frac{76x}{76}=\frac{2200}{76}[/tex]
[tex]x=\frac{2200}{76}=28.947[/tex]
since you're not going to have .947 of a question, round it up to 29
and then you have it
[tex]x=29[/tex]
8. You are a bakery chef. You have ordered
14 pounds of green apples and 9 pounds of
red apples. You have also ordered twice as many
yellow apples as red. You used 26 pounds of
apples for pies. How many pounds of apples
do you have left?
+
Answer: 15 pounds of apples left!
Step-by-step explanation:
Yellow: 9 times 2 = 18 apples
Red: 9
Green: 14
Add them all together- 18 plus 9 plus 14 =41.
Subtract 26 from 41 = 15
15 pounds of apples left!
Which transformation produces another triangle that has the same area as the one shown?
Answer:
A
Step-by-step explanation:
A reflection in the line y = -2 and then translation of 2 units right will create the same area so option (C) will be correct.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
If we shift the triangle anywhere then there will be no change in the area but if we apply the scale factor then since the dimension changes so its area will also change.
In all options, there is a scale factor so it will change area but in option C
A reflection in the line y = -2 reflection gives a mirror image about y = -2 but no changes in area then translation of 2 units right will shift triangle 2 units right but no effect in the area.
Hence "A reflection in the line y = -2 and then translation of 2 units right will create the same area".
