All you gotta do is make it so the diagram displays x being 13

Answer:

11. 35 ft²

12. 24 cm²

13. 18 ft²

14. 28 in²

15. 9 in²

Step-by-step explanation:

11. A= (b×h)÷2

= (10×7)÷2

= 70 ÷ 2

= 35 ft²

12. A= (b×h)÷2

= (8×6)÷2

= 48 ÷ 2

= 24 cm²

13. A=(b×h)÷2

=(9×4)÷2

= 36 ÷ 2

= 18 ft²

14. A=(b×h)÷2

=(7×8)÷2

= 56 ÷ 2

= 28 in²

15. A=(b×h)÷2

=(3×6)÷2

= 18 ÷ 2

= 9 in²

Good luck ^_^

Answer:

18

Step-by-step explanation:

90/5=18

Answer:

± 15 cm  

Step-by-step explanation:

In the first case, since the measurement is 1 cm too long or too short, the error is ± 1 cm.

In the second case, the uncertainty or error is also ± 1 cm.

Now, since there are 15 cars, and there is an error of ± 1 cm in each measurement, by the error formula the total error in the sum of both cases is 15 × ±1 cm = ± 15 cm  

So, the total error in both cases is ± 15 cm.

Step-by-step explanation:

The mean for 2018 scores is:

[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]

[tex]M ean ( \overline X) = \dfrac{74 + 78+79+77+75+73+75+77}{8}[/tex]

[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]

[tex]\mathbf{M ean ( \overline X) = 76}[/tex]

The standard deviation for 2018 scores is:

[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]

[tex]s = \sqrt{\dfrac{ ( 74 -76)^2+( 78 -76)^2+( 79 -76)^2+...+( 73 -76)^2+( 75 -76)^2+( 77 -76)^2}{8- 1} }[/tex]

[tex]s = \sqrt{\dfrac{30}{7} }[/tex]

s = 2.07

The mean and standard deviation for the year 2018 scores is:

                                     2018

Mean                                 76

Standard deviation       2.07

The mean for 2019 scores is:

[tex]M ean ( \overline X) = \dfrac{\sum x_i}{n}[/tex]

[tex]M ean ( \overline X) = \dfrac{71 + 70+75+77+85+80+71+79}{8}[/tex]

[tex]M ean ( \overline X) = \dfrac{608} {8}[/tex]

[tex]\mathbf{M ean ( \overline X) = 76}[/tex]

The standard deviation for 2019 scores is:

[tex]s = \sqrt{\dfrac{\sum ( x_i - \bar x)^2}{n- 1} }[/tex]

[tex]s = \sqrt{\dfrac{ ( 71 -76)^2+( 70 -76)^2+( 75-76)^2+...+( 80 -76)^2+( 71 -76)^2+( 79 -76)^2}{8- 1} }[/tex]

[tex]s = \sqrt{\dfrac{194}{7} }[/tex]

s = 5.26

The mean and standard deviation for the year 2019 scores is:

                                     2019

Mean                                 76

Standard deviation       5.26

Difference: Both the two years have the same mean but the 2019 scores have higher variation as compared to 2018 scores.

Thus, the variation in scores was higher in 2019.

Answer:

Step-by-step explanation:

We are given:

There were 7 chocolate bars, evenly shared between 4 friends

Number of Bars one person will get:

Number of bars one person will get = Number of Bars / Number of Friends

Number of Bars = 7 / 4

but since this number does NOT match any of the given options, we will convert it to a mixed fraction

The number of bars one person will get will be [tex]1\frac{3}{4}[/tex], written as a mixed fraction.

Therefore, the correct answer is option D

Answer:

4 friends =7 chocolate

1 friend =7/4 chocolate =1 3/4 part of chocolate.

Answer:

$1.88

Step-by-step explanation:

11.28 / 6 = 1.88

Answer: $1.88

Step-by-step explanation:

We have 6 pounds of candy that cost 11.28, and we need to find the unit rate.

If we want to find the unit rate, or the cost per pound, we can use the equation 11.28 ÷ 6.

We can then divide each side by 6, or solve the equation.

11.28 ÷ 6 = 1.88.

Therefore, the each pound of candy costs $1.88.

b) n + n + 1 + n + 2 + n + 3

c) s = n + n + 1 + n + 2 + n + 3

Answer:

Number of cups of lemonade = 59 cups

Step-by-step explanation:

Given the linear function :

C = 2t - 89

At temperature of 74° ;

The cups of lemonade as calculated using the linear model:

C = 2t - 89 ; where c = cost of lemonade ; t = temperature.

C = 2(74) - 89

C = 148 - 89

C = 59

A function assigns the values. The prediction that she will sell 40 cups of lemonade that day is wrong.

A function assigns the value of each element of one set to the other specific element of another set.

As it is given that function, c=2t-89, where the number of cups of lemonade is represented by c, and t represents the temperature of the day.

Now, as it is given that the temperature at the day is 74, therefore, the number of cups that will be sold that day can be predicted as,

[tex]c = 2t-89\\\\c = 2(74)-89\\\\c = 148-89\\\\c = 59[/tex]

Hence, the prediction that she will sell 40 cups of lemonade that day is wrong.

Answer and explanation:

One route goes up and down the hill while the other goes around the edge of the hill, in other words one route goes through a hill to get to the destination while the alternative route has a tunnel that makes it possible to avoid the hill.

Relationship between distance and time is given by the formula:

Distance = Speed × time

For example to find the distance travelled with a speed of 10km/hr and 4 hours travelled, we simply multiply speed 10km/hr by time travelled 4 hrs = 40km

Answer:

2833.3 miles

Step-by-step explanation:

Answer:

a. 2 inches = 1 mile

Step-by-step explanation:

Answer:

Here we have the equation:

y = 4*x^2 - 4*x - 1

And we should have the graph (you can see it below this answer)

Now we want to find the solutions of:

4*x^2 - 4*x - 1 = 0

These solutions will be the two values of x at which the graph of our function intersects the line y = 0, that is the x-axis.

Then we need to find the two values of x at which our graph intersects the x-axis.

In the graph, we can estimate the solutions as:

x = -0.2

x = 1.2

To find the exact solutions we can use the Bhaskara's equation, and we will find that the solutions are given by:

[tex]x = \frac{-(-4) +- \sqrt{(-4)^2 - 4*4*(-1)} }{2*4} = \frac{4+ -\sqrt{32} }{8} = \frac{4 +-5.66}{8}[/tex]

Then the two solutions are:

x = (4 + 5.66)/8 = 11.2075

x = (4 - 5.66)/8 = -0.2075

Step 1: Locate and underline the tenth place (4) and look to the right (8)

1.48

Step 2: In this case, the digit to the right 8 is 5 or above. So, we add 1 to the tenth place 4. The digit at the right 8 becomes 0, thus we get 1.5 as the answer.

In short: 1.48 rounded to the nearest tenth is 1.5.
