Answer:

It is 8 3 pointers and 13 2 pointers

Step-by-step explanation:

8 x 3 = 24

13 x 2 = 26

24 + 26 = 50

The bulldogs made 13 2-pt shots and 8 3-pt shots.

Let's assume that the bulldogs made x 2-pt shots and y 3-pt shots. Since each 2-pt shot is worth 2 points and each 3-pt shot is worth 3 points, we can set up the following equations: 2x + 3y = 50 (equation 1) and x + y = 21 (equation 2). To solve this system of equations, we can multiply equation 2 by 2 to get 2x + 2y = 42, and then subtract equation 1 from it. This gives us y = 8. Substituting y = 8 into equation 2, we get x + 8 = 21, which means x = 13. Therefore, the bulldogs made 13 2-pt shots and 8 3-pt shots.

Answer:

1968

Step-by-step explanation:

I use the following method when it comes about products of big numbers

I grab the longer and put on the first line, below I put the smallest number.

492

x 4

Now, it is time to distribute the product, term by term, remember that when performing a product, if the result is greater or equal than 10, you need to carry a number for the following product.

      492

        x 4

--------------------

   19    6    8

(end) (c3) (nc)

nc means: not carrying anything since 4x2=8 and 8 <10

c3 means: carrying 3 since 4x9= 32 and 32 >10

end means: put the whole number and sum it what you were carrying. 4*4+3=19

The product 492*4=1968

The product of 4 multiplied by 492 equals 1968. To find this, we used a step-by-step approach using basic multiplication and the distributive property.

To determine the product of 4 multiplied by 492, you can execute the following steps:

Therefore, 4 × 492 = 1968.

The question is asking to identify how many days will pass before Heather will have both a jelly sandwich and milk again, given that she eats a jelly sandwich every 5th day and drinks milk every 4th day. To find out when Heather will have both on the same day again, we need to find the Least Common Multiple (LCM) of the two numbers, 5 and 4.

The multiples of 5 are 5, 10, 15, 20, 25, and so on. The multiples of 4 are 4, 8, 12, 16, 20, and so on. The first common multiple of both 5 and 4 is 20. Therefore, Heather will have both a jelly sandwich and milk together on every 20th day after today.

So, after today, Heather will wait 19 more days before having both a jelly sandwich and milk on the same day again.

Hello...

Tony and his three friends live in Albuquerque, New Mexico, but they all attend college in Boston, Massachusetts. Because they want to have a car at school this year, they are planning to drive Tony's car from Albuquerque to Boston at the beginning of the school year. Although they'll each pay for their own food during the road trip, the friends plan to split the costs for gas and hotels evenly between the four of them.

Estimate the total cost that each friend will have to pay for gas and hotels. Explain how you got your answer. Here are some figures that may help you out:

•Tony's car can travel 28 miles for each gallon of gas.

•The average fuel cost at the time of their trip is $3 per gallon.

•They plan to drive about 650 miles each day.

•They estimate the average cost of a hotel each night is $85.

•They will drive approximately 2,240 miles to get from Albuquerque to Boston.

Solution:

Cost of Gas:

2240 / 28 x 3 = $240

Cost of Lodging:

85 x floor2240 / 650 = $255

Cost of both: $240 +255 = $495.

The cost for a 1/4 share is $495/4 = $123.75.

CE is equal to 58 units.

To find the length of CE, we'll use the fact that D is the midpoint of CE. The midpoint of a line segment divides it into two equal parts.

If CD is one part and DE is the other, then we can set up an equation:

CD=DE

9X−7=3X+17

Now, solve for X:

6X=24

X=4

Now that we have the value of X, substitute it back into either CD or DE to find the length of each part:

CD=9X−7=9(4) −7=36−7=29

DE=3X+17=3(4) +17=12+17=29

Now, since D is the midpoint, CD and DE are equal.

CD=DE=29

Finally, CE, the total length, is the sum of CD and DE:

CE=CD+DE=29+29=58

So, CE is indeed 58

a total of $9500 is invested, part at 10% simple interest and part at 9%

if the total annual return from the two investments is $914.00

Amount invested = 9500

Total amount return means total yield = $914

Let x amount  is invested at 10% simple interest

Interest for first part =  10 % times x = 0.10x

Remaining part invested is 9500 -x

Interest for remaining amount = 9% (9500 -x) = 0.09(9500-x)

Total interest yield is 914. Now we frame an equation

0.10x + 0.09(9500-x) = 914

0.10x +855 - 0.09x = 914 (combine like terms)

0.01 x + 855 = 914 (subtract 855)

0.01x = 59 ( divide both sides by 0.01)

So x = 5900

$5900 is invested in 10% simple interest

9500 - 5900 = $3600 is invested in 9% simple interest

Final answer:

To solve the problem, we set up a system of equations based on the provided information. After simplifying and solving the system, we find that $5900 is invested at 10% and $3600 is invested at 9%.

Explanation:

Investment Allocation Problem

Let's denote the amount of money invested at 10% as $x and the amount of money invested at 9% as $y. Since the total amount invested is $9500, we can write the first equation as:

x + y = 9500

The total annual return from the investments is $914. We know that the interest from the first investment is 0.10x and from the second investment is 0.09y. Thus, our second equation, based on the total interest earned is:

0.10x + 0.09y = 914

Now we can solve the system of equations:

x + y = 9500 (Equation 1)

0.10x + 0.09y = 914 (Equation 2)

Multiplying Equation 1 by 0.10 gives us a new equation:

0.10x + 0.10y = 950 (Equation 3)

Now, we subtract Equation 2 from Equation 3:

(0.10x + 0.10y) - (0.10x + 0.09y) = 950 - 914

0.10y - 0.09y = 36

0.01y = 36

y = 3600

Substitute y = 3600 into Equation 1 to find x:

x + 3600 = 9500

x = 5900

Therefore, $5900 is invested at 10% and $3600 is invested at 9%.

8^14 is the answer.

2) angles are vertical so they are congruent- 7x-27= 4x+12 --> subtract 4x from both sides so 3x-27=12 --> add 12 to both sides so 3x=39 (divide both sides by 3) so then x= 13

3) again, vertical angles so 8x-120= 4x+16 --> subtract 4x so that 4x-120=16 --> add 120 to both sides and then 4x=136, divide both by 4 and x= 34

Final answer:

To find the actual distance from Rose Lake to the hiking trail, a proportion is used based on the given information of the map scale, resulting in an actual distance of 7 miles.

Explanation:

The question involves solving for an actual distance on a map scale, which is a proportional relationship problem in mathematics. To find the actual distance between Rose Lake and the hiking trail, we can set up a proportion using the given distances: if 2 inches on the map equal 3.5 miles in reality, then 4 inches would represent the distance from Rose Lake to the hiking trail (since the relationship between inches on the map and actual miles should be consistent).

Set up the proportion as follows:

2 inches (map) / 3.5 miles (real) = 4 inches (map) / X miles (real)

Now, solve for X, which represents the unknown actual distance in miles. By cross-multiplying and solving for X, we get:

X = (4 inches * 3.5 miles) / 2 inches

Therefore, the actual distance between Rose Lake and the hiking trail is 7 miles.

First the two angles are equal to one another so take note of that.

Now setup the equation which will be

x+90=4x

Now get rid of alike terms

So subtract x from both sides

90=3x

Now divide 90 by 3

x=30

Answer:  The correct option is

(C) x = 30.

Step-by-step explanation:  We are given to find the value of x from the figure shown.

From the figure, we note that the angles with measures (x+90)° and 4x° are vertically opposite angles.

Since the measures of two vertically opposite angles are equal, so we must have

[tex](x+90)^\circ=4x^\circ\\\\\Rightarrow x+90=4x\\\\\Rightarrow 4x-x=90\\\\\Rightarrow 3x=90\\\\\Rightarrow x=\dfrac{90}{3}\\\\\Rightarrow x=30.[/tex]

Thus, the required value of x is 30.

Option (C) is CORRECT.

The formula of a midpoint:

[tex]M_{AB}\left(\dfrac{x_A+x_B}{2},\ \dfrac{y_A+y_B}{2}\right)[/tex]

We have:

[tex]A(7,\ 12)\to x_A=7,\ y_A=12\\B(-1,\ 6)\to x_B=-1,\ y_B=6[/tex]

Substitute:

[tex]\dfrac{7+(-1)}{2}=\dfrac{7-1}{2}=\dfrac{6}{2}=3\\\\\dfrac{12+6}{2}=\dfrac{18}{2}=9[/tex]
