CAN SOME ONE PLS HELP ME THIS IS REALLY HARD
Answer: 1.25 times as far
Step-by-step explanation:
This problem requires you to find something called the unit rate.
Getting the unit rate for Car A is very simple, and can be found to be 25mi/gal.
To find the unit rate for Car B, simply look at the second row. Because the car can go 60 miles on 3 gallons of gas, divide both these numbers by 3 to get 20mi/gal.
Then, simply multiply both of these numbers by 11 to get 25 * 11 = 275, and 20 * 11 = 220.
Then, by doing 275/220, you get your answer: 1.25.
Hope it helps :) and let me know if you want me to elaborate.
Car A can travel 275 miles and car B can travel 220 miles

Step-by-step explanation:
What is the base of 4×4×4×4×4?
Answer:
Step-by-step explanation:
Your base would be the 4
Answer:
4
Step-by-step explanation:
When you have a something raise up to a number this can be represented as:
[tex]b^a = b_1 \cdot b_2 \cdot \cdot \cdot b_a[/tex]
Where [tex]b[/tex] is the base and [tex]a[/tex] the exponent. In this case you have five times four, then you can re-write the expression as:
[tex]4 \times 4 \times 4 \times 4 \times 4 = 4^5[/tex]
Where the [tex]b[/tex] is equal to 4 and [tex]a[/tex] equal to 5
Work out the area of the parallelogram.
13 cm
790
21 cm
Answer:
Step-by-step explanation:
please try to provide a more accurate information 13cm of what? 790?
Answer:
The area of parallelogram can be found by product of its base and height. The calculations are shown below:
Step-by-step explanation:
We know that,
Area of parallelogram = base × height
assume base to be 21 cm.
Then,
sin 79° = [tex]\frac{height}{13}[/tex]
∴ height = 13 × 0.98 = 12.74
Area of parallelogram = 21 × 12.74
= 267.54 [tex]cm^{2}[/tex]
The area of parallelogram is calculated as 267.54 [tex]cm^{2}[/tex]

Which statement best explains if the graph correctly represents the proportional relationship y = −2x? A coordinate plane is shown. Points are graphed at negative 2 and 4 and negative 1 and 2. The points are joined by a line. It does not, the points shown would not be part of y = −2x. It does not, proportions cannot be represented on a graph. It does, all proportions can be shown on a graph of this line. It does, the points shown on the line would be part of y = −2x.
Answer:
d. It does, the points shown on the line would be part of y = −2x.

3x + 3y = 9
-3x + 2y = 1
Answer:
X=1
Y=2
Step-by-step explanation:
put 1 in for X
3(1)+3(y)=9
-3(1)+2(y)=1
now put 2 for Y
3(2)+3(2)=9
-3(1)+2(2)=1
3•1= 3
3•2=6
3+6=9
-3•1=-3
2•2=4
-3+4=1
Find the slope of the line that passes through:
(5, -10) and (5,-4)
Answer:
Undefined
Step-by-step explanation:
you use the slope formula
m = y2 - y1 / x2 - x1
substitute
m = -4 - (-10) / 5 - (-5)
subtract 5 from 5
- 4 - (-10) / 0
The expression contains a division by 0. The expression is undefined.

^-2/5x > -8
Then multiply both sides of the inequality by ^-5/2 and flip the inequality sign
Which gives you:
x < 20
Answer:
Step-by-step explanation:
one would flip the sign on (-2/5)x > -8 because you would be multiplying by a negative number (- 5/2) to get positive x standing alone. It resolves to
x < 20
You would also flip the sign on
-x + ¾ < 10
-x + ¾ - ¾ < 10 - ¾
-x(-1) > 9¼(-1) multiplying by a negative number flips the sign.
x > - 9¼
Solve 2 cot x = csc^2 x symbolically on the interval (0,2pi).
Answer:
x=pi/4, 5pi/4
Step-by-step explanation:
cot x = cos x / sin x, csc x = 1/sin x, so we have 2 cos x / sin x = 1/ sin^2 x. multiply both sides by sin^2 x to get 2 cos x * sin x = 1, divide both sides by 2 to get cos x sin x = 1/2, this would work for angles pi/4 and 5pi/4 (3pi/4 and 7pi/4 would make cos x sin x = -1/2) since cos x = sin x = sqrt(2)/2
Use technology to find the P-value for the hypothesis test described below.
The claim is that for a smartphone carrier's data speeds at airports, the mean is p = 19.00 Mbps. The sample size is n = 21 and the test statistic is t= 1.401
P-value = (Round to three decimal places as needed)
Using the t-distribution, it is found that the p-value is of 0.177.
At the null hypothesis, it is tested that for a smartphone carrier's data speeds at airports, the mean is 19 Mbps, that is:
[tex]H_0: \mu = 19[/tex]
At the alternative hypothesis, it is tested if the mean is different than 19 Mbps, that is:
[tex]H_1: \mu \neq 19[/tex]
We are testing if the mean is different from a value, hence it is a two-tailed test.The test statistic is t = 1.401.Sample size of n = 21, hence there are 21 - 1 = 20 df.Inputting this information into a calculator, the p-value is of 0.177.

calculate the Geometric mean for the
distribution 8, 6, 3, 5 and 4
Answer:
Step-by-step explanation:
The geometric mean is the average of the 5 numbers
8 + 6 + 3 + 5 + 4 Just add.
Total = 26
There are 5 elements, so the average = 26/5 = 5.2
