Answer : The length of BC in the right triangle is, 75

Step-by-step explanation :

Using Pythagoras theorem in ΔBAC :

[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]

[tex](BC)^2=(AB)^2+(AC)^2[/tex]

Given:

Side AB = 21

Side AC = 72

Now put all the values in the above expression, we get the value of side BC.

[tex](BC)^2=(21)^2+(72)^2[/tex]

[tex]BC=\sqrt{(21)^2+(72)^2}[/tex]

[tex]BC=\sqrt{441+5184}[/tex]

[tex]BC=\sqrt{5625}[/tex]

[tex]BC=75[/tex]

Therefore, the length of BC in the right triangle is, 75

Answer:

B. He was not correct since .64 x 100 = 64

Step-by-step explanation:

100 x .64

400 + 6000 = 6400

64.

The question asks if Tyrone's estimation that 100 boxes of macaroni, each weighing .64 pounds, would total 640 pounds. The estimation is correct as the multiplication .64 x 100 equals 640.

The subject of this question is Mathematics and it is a middle school level problem. The question revolves around the concept of simple multiplication and estimation. If Tyrone estimated that 100 boxes of macaroni would weigh 640 pounds based on the fact that one box weighs .64 pounds, he is correct.

This is affirmed by conducting the simple multiplication calculation: .64 (the weight of a single box) multiplied by 100 (the number of boxes) equals 640.

The mathematical representation of this can be expressed as .64 x 100 = 640. Therefore, Tyrone's estimation is correct.

The change in the number of gallons of water in the tank after 7 days is 35 gallons.

The water tank leaks 5 gallons of water each day. To find the change in the number of gallons of water in the tank after 7 days, we multiply the amount leaked per day (5 gallons) by the number of days (7). The expression for the change in gallons can be written as:

Change in gallons = amount leaked per day × number of days

Change in gallons = 5 × 7

Change in gallons = 35 gallons

https://brainly.com/question/31940138

#SPJ3

Final answer:

The integer representing the change in the number of gallons of water in the tank after 7 days is -35, as the tank loses 5 gallons per day.

Explanation:

If a water tank leaks 5 gallons of water each day, the total amount of water it would lose in seven days is calculated by multiplying the daily water loss by the number of days. The calculation steps are:

Determine the daily water leakage: 5 gallons per day.

Multiply the daily leakage by the number of days: 5 gallons/day × 7 days.

Calculate the total leakage over seven days: 35 gallons.

As water is being lost from the tank, the change in the number of gallons in the tank after 7 days would be represented by a negative integer, since it is a decrease in the volume of water. Therefore, the integer representing the change in the water level is -35.

Answer:

the required equation is y = ( -2/3 )x -7

Step-by-step explanation:

Given :-

the line passes through the point ( 0 , -7 )

)and slope of the line is ( -2/3 )

• To form an equation when one point and it's slope is given ,

• To form an equation when one point and it's slope is given , we use ;

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variables

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variablesand x1 and y1 are the points where the line meet !

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variablesand x1 and y1 are the points where the line meet ! and m is slope of the tangent !!

y1 = -7

x1 = 0

So, putting all the values in the equation we get ,

[tex](y - ( - 7)) = \frac{( -2 )}{3} (x - 0) \\ \\ y + 7 = \frac{ - 2}{3} x \\ \\ 3y + 21 = - 2x \\ \\ 3y = - 2x - 21[/tex]

[tex]3y = - 21 - 2x \\ \\ y = \frac{ - 2}{3} x - \frac{21}{3 } \\ \\ y = \frac{ - 2}{3} x - 7[/tex]

• Slope intercept form of the equation

• Slope intercept form of the equation y = mx + c

• Slope intercept form of the equation y = mx + c Where , m is slope of the line

• Slope intercept form of the equation y = mx + c Where , m is slope of the line and c is y intercept !!

[ also , we can directly put the value of c = -7 and m = ( -2/3 ) from given ]

Hence , here m = (-2/3 ) and c = -7

So, the required equation is y = ( -2/3 )x -7

Answer: 20 meters.

Step-by-step explanation:

The formula for calculate the area of a square is:

[tex]A=s^2[/tex]

Where "s" is the side length of the square:

The formula for calculate the area of a rectangle is:

[tex]A=lw[/tex]

Where "l" is the lenght and "w" is the width.

Based on the information provided, you know the sum of the areas of the square land and the adjacent land is 600 m². This is:

[tex]A_1+A_2=600\\\\s^2+lw=600[/tex]

Knowing that the width of the adjacent land is 10 meters:

[tex]s^2+10l=600[/tex]

Since  the lenght of the adjacent land and the side lenght of his actual land are equal:

[tex]l=s[/tex]

You can substitute this into [tex]s^2+10l=600[/tex]:

[tex]s^2+10s=600\\\\s^2+10s-600=0[/tex]

Applying the Quadratic formula, you get:

[tex]s=\frac{-b\±\sqrt{b^2-4ac} }{2a}\\\\s=\frac{-10\±\sqrt{(10)^2-4(1)(-600)} }{2(1)}\\\\s_1=20\\\\s_2=-30[/tex]

Since the side lenght cannot be negative, you can determine that this is:

[tex]s=20\ m[/tex]

To determine which mixing bowl to use for combining[tex]\frac{11}{2}[/tex]cups of flour, [tex]\frac{3}{4}[/tex] cup of white sugar, and [tex]\frac{1}{8}[/tex] cup of brown sugar, their volumes need to be added, resulting in a total of 2.375 cups. The suitable bowl size is the 3-cup bowl, as it is larger than the combined ingredient volume.

The student's question relates to determining which size of mixing bowl is required to accommodate the ingredients for a recipe, based on their total volume. To solve this problem, we should add the volumes of flour, white sugar, and brown sugar together:

[tex]\frac{3}{4}[/tex] cup white sugar

[tex]\frac{1}{8}[/tex]cup brown sugar

By converting these measurements to a consistent unit (cups) and adding them, we get:

1.5 cups (flour) + 0.75 cups (white sugar) + 0.125 cups (brown sugar) = 2.375 cups

Since the total volume of the ingredients is 2.375 cups, the smallest bowl that can be used is the one that holds more than 2.375 cups. Therefore, the 3-cup bowl will be sufficient for mixing the ingredients.

Answer:

Step-by-step explanation:

a.  So since it doesn't say anything else after Monday for that week we assume he only got the apples Monday. Now, if you're having trouble figuring out how much he got from selling all 30 try thinking about selling one at a time.  one is 3.45, two is 6.90 and so on.  So you multiply the amount by how many there are.  so 30*3.45.

b.  Second week is similar, 26*3.45

c.   it wants to know how much in total, so just add the two results.  30*3.45 + 26*3.45.

d.  So, each bag has 15.  You can use similar thinking.  one bag is 15, two is 30 and so on.  Writing an expression  means putting a variable in.  let's say x is the number of bags.  To find the number of apples you multiply it by 15.  so 15x.  Now, to find how many apples were gotten int he two weeks we want x to equal the total number of bags, which is 30+26.

If there was something you didn't understand let me know and I will explain it.  

Answer:

a. [tex]\$103.5[/tex]

b. [tex]\$89.7[/tex]

c. [tex]\$193.2[/tex]

d. Expression: [tex]15(30+26)[/tex]

    He picked 840 apples in two weeks.    

Step-by-step explanation:

We know that he sold each bag for $3.45.

a. Let be "x" the amount of money Juwad earned in the first week. To find its value we need to multiply the price of one bag by the number of bags he sold the first week.

Since he sold 30 bags that week,we get:

[tex]x=(\$3.45)(30)=\$103.5[/tex]

b. In the second week Juwad sold 26 bags.

Let be "y" the amount of money Juwad earned in the second week.

We must multiply the price of one bag by 26 bags in order to find the value of "y". This is:

[tex]y=(26)(\$3.45)=\$89.7[/tex]

c. The  amount of money he earned selling bags of apples those two weeks is:

[tex]total\ earned=x+y\\\\total\ earned=\$103.5+\$89.7\\\\total\ earned=\$193.2[/tex]

d. We already know that he picked 30 bags of apple in the first week and 26 in the second week.

Since each bag holds 15 apples, we can wrie the following expression to represent the number of apples he picked in two weeks:

[tex]15(30+26)[/tex]

Evaluating the expression, we get:

[tex]15(56)=840[/tex]

He picked 840 apples in two weeks.

Answer:

The delivery person can bring up max 16 boxes at one time.

Step-by-step explanation:

The elevator can only hold max 850 lbs, and the delivery man weighs 180 lbs.

850-180=670

That means the delivery man can have up to 670 lbs of boxes on the elevator.

670/40=16.75

Which means that the delivery man can hold up to 16 boxes max at one time.

With the delivery person's weight and the maximum capacity of the elevator considered, the maximum number of 40 lb boxes of books the delivery person can bring up at once is 16.

This question is about problem-solving and arithmetics. In this context, the maximum weight the elevator can carry is 850 lb. The delivery person's weight of 180 lb must be included in this maximum. To figure out how many boxes of books at 40 lb each the delivery person can carry, one would have to subtract the delivery person's weight from the total maximum weight and then divide this total by the weight of each box.

By doing the subtraction, 850 lb (maximum capacity) - 180 lb (weight of delivery person) = 670 lb. This is the total weight of boxes that can be carried. Then, divide this remaining weight by the weight of each box: 670 lb / 40 lb = 16.75 boxes. Since one cannot have 0.75 of a box, the maximum number of boxes that can be carried at one time is 16.
