Answer:
the answer is 9 hours
Step-by-step explanation:
I got it right on the test
The time taken by Jan and Jo with constant rate of 70 mph and 60 mph respectively, will meet in 9 hours while driving towards each other along a 1,170-mile road.
To find out how long it will take Jan and Jo to meet, you can use the formula:
Time = Distance / Speed
Since they are driving toward each other, their combined speed is the sum of their individual speeds:
Combined Speed = Jan's Speed + Jo's Speed
Combined Speed = 70 mph + 60 mph
Combined Speed = 130 mph
Now, you can use this combined speed to calculate the time it will take for them to meet:
Time = Distance / Combined Speed
Time = 1,170 miles / 130 mph
Time = 9 hours
Therefore, time taken by Jan and Jo is 9 hours to meet while driving toward each other on the same road.

What is the sum of each pair of binary integers?
a. 10101111 + 11011011
b. 10010111 + 11111111
c. 01110101 + 10101100?
Final answer:
The sums for the given pairs of binary integers are: a. 10101111 + 11011011 equals 110001010, b. 10010111 + 11111111 equals 110010110, c. 01110101 + 10101100 equals 100100001.
Explanation:
The sum of each pair of binary integers is calculated using binary addition rules, which are similar to decimal addition, but instead, you only have two digits, 0 and 1, and carry over whenever you add two 1's. Let's perform the calculations for each given pair:
a. 10101111 + 11011011 = 110001010
b. 10010111 + 11111111 = 110010110
c. 01110101 + 10101100 = 100100001
Remember to start adding from the rightmost digit (least significant bit) and move left, carrying over as necessary when the sum of two bits is 2 (binary 10).

Jessica is making a repeating pattern following the rule “triangle square circle what will be the 50th shape in the pattern?
The 50th shape in the repeating sequence of shapes (triangle, square, circle) is a square. This conclusion is reached by dividing 50 by the 3 shapes in the sequence and noting that the remainder indicates the position in the sequence.
Explanation:The problem presented is one of patterns and sequences, a common topic explored in middle school mathematics. The repeating pattern here consists of three shapes: a triangle, a square, and a circle. This sequence of three shapes continues indefinitely.
To find the 50th shape in the sequence, divide 50 by 3. You'll get 16 remainder 2. This indicates that after 16 complete cycles of the pattern (each consisting of a triangle, square, or circle), the 50th shape is the 2nd shape in the next cycle - the square. Hence the 50th shape according to Jessica's rule is a square.

The 50th shape in the repeating pattern of Triangle, Square, Circle is a Square.
To find the 50th shape, we need to understand the cyclical nature of this pattern, which repeats every 3 shapes.
Step-by-Step Solution:
The pattern repeats every 3 shapes: Triangle (1), Square (2), Circle (3).To find the position of the 50th shape within this cycle, we calculate the remainder of 50 divided by 3:Therefore, the 50th shape is a Square.

A business woman invests $38,000 into two accounts: one that returns 3.5% annual interest and one that returns 6.5% annual interest. After 1 year, she earns $1960. How much did she invest in each account?
$23,000 in the 3.5% interest account, $15,000 in the 6.5% interest account.
$26,000 in the 3.5% interest account, $12,000 in the 6.5% interest account.
$12,000 in the 3.5% interest account, $26,000 in the 6.5% interest account.
$17,000 in the 3.5% interest account, $21,000 in the 6.5% interest account.
Final answer:
The business woman invested $17,000 in the 3.5% interest account and $21,000 in the 6.5% interest account.
Explanation:
To find how much she invested in each account:
Let x be the amount invested at 3.5% interest and y be the amount at 6.5%.
We can set up a system of equations like this: x + y = $38,000 and 0.035x + 0.065y = $1,960.
Solving this system, we get x = $17,000 and y = $21,000.
Therefore, investment is $17,000 in the 3.5% interest account, $21,000 in the 6.5% interest account

The value obtained as the power of 2 after solving the expression, (4×2⁵) ÷ (2³ × 1/16 ) will be 2⁸.
What is an integer exponent?In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
The given expression is,
(4×2⁵) ÷ (2³ × 1/16 )
Keep the base constant and add the exponents when multiplying similar bases. Maintaining the same base while multiplying the exponents will raise a base with power to another power. When dividing two bases with similar exponents, keep the exponents of the numerator and denominator constant.
= (2² × 2⁵) ÷ (2³ × 2⁻⁴ )
= (2⁷) ÷ (2⁻¹)
= 2⁸
Thus, the values obtained as the power of 2 after solving the expression, (4×2⁵) ÷ (2³ × 1/16 ) will be 2⁸.

which least to greatest 125% 6/5 1.22
Final answer:
To compare the numbers 125%, 6/5, and 1.22, they were all converted to decimal form which revealed the least to greatest order as 1.22, 6/5, and 125%.
Explanation:
To arrange the numbers 125%, 6/5, and 1.22 from least to greatest, we first need to express all of them in the same format for an accurate comparison. Let's convert each number to a decimal:
125% as a decimal is 1.25 (since 100% is equal to 1, hence 125% is 1.25).6/5 as a decimal is 1.2 (6 divided by 5 equals 1.2).1.22 is already in decimal form.Now, we can easily compare:
1.226/5 (1.2)125% (1.25)The arrangement from least to greatest is 1.22, 6/5, 125%.
Last year Milwaukee had the total of snow amounting to 92 inches . The normal fall is 52 1/4 inches . How much above normal was the snowfall last year .
The snowfall in Milwaukee last year was 39.75 inches above the normal amount, calculated by subtracting the normal annual snowfall from last year's total.
Explanation:The student's question is related to subtraction of two amounts to find the difference between the actual snowfall and the normal snowfall in Milwaukee.
To determine how much above normal last year's snowfall was, we subtract the normal snowfall amount from last year's total snowfall.
Last year's snowfall in Milwaukee = 92 inches
Normal annual snowfall = 52 1/4 inches
To find how much above normal the snowfall was, we calculate:
92 inches - 52 1/4 inches = 92 inches - 52.25 inches
This equals 39.75 inches above normal snowfall.
