Answer:

Step-by-step explanation: 7 miles: 3/4 hour, 9/8 miles: 5/6 hour, and 4 miles: 3 and 1/3 hour.

hope this helps !! <3

The ratios that have a unit rate is 9/8 miles:5/6hours and 7miles: 3/4 hours

Unit rate is the ratio of the distance travelled o the time taken.

For us to know which of the ratios has a unit rate greater than 1, we need to divide the distance by the time as shown;

If distance = 9/8 miles and time = 5/6 hours

[tex]Unit \ rate =\frac{(9/8)}{(5/6)}\\Unit \ rate =\frac{9}{8} \times \frac{6}{5}\\Unit \ rate = \frac{54}{40} \\Unit \ rate =1.35 miles/hour[/tex]

Hence the ratio that has a unit rate is 9/8 miles:5/6hours

If distance = 7 miles and time = 3/4 hours

[tex]Unit \ rate =\frac{7}{(3/4)}\\Unit \ rate =\7 \times \frac{4}{3}\\Unit \ rate = \frac{28}{3} \\Unit \ rate = 9.33miles/hour[/tex]

Hence the ratio that has a unit rate is 7 miles:3/4hours

Answer:

x ÷ 4 + 17

Step-by-step explanation:

17 more than the quotient of a number and 4. You're adding 17 to the quotient of x and 4, or x divided by 4.

The expression "17 more than the quotient of a number and 4" can be written as:

(x / 4) + 17

In this expression, x represents the unknown number. We divide x by 4 to find the quotient of the number and 4, and then add 17 to it.

For example, if we substitute x = 12 into the expression, we would have:

(12 / 4) + 17 = 3 + 17 = 20

Therefore, the value of the expression "17 more than the quotient of a number and 4" depends on the specific value of x that is substituted into the expression.

Answer:

D) Emerson must earn at least a 94 on his final test to earn an “A” in his class

Step-by-step explanation:

We calculate this using mean in this format:

Test Scores / # of Test ≥ 90 (which is an A)

Substitute:

(92 + 86 + 88)+ x / 4 ≥ 90

Add:

266 + x / 4 ≥ 90

Get Rid of the Denominator:

(4) 266 + x / 4 ≥ 90 (4)

Multiply:

266 + x ≥ 360

Isolate x (Subtract 266 From Both Sides):

x ≥ 94

This means that x (His final test score) has to be greater than (above) or equal to 94. A term for greater than or equal to is “at least.” Hope this helps :)

Answer:

a = 195 m , b = 180 m , c = 75 m  

Step-by-step explanation:

Let "a,b and c" be the sides of the triangle in the ration - 13:12:5

therefore , a:b:c = 13:12:5 => a = 13x , b = 12x , and c = 5x

therefore , Perimeter = 13x + 12x + 5x = 450

=> 30x = 450

=> x = 15

therefore , a = 13 x 15

b = 12 x 15 and

c = 5 x 15

hence , a = 195 m , b = 160 m and c = 75 m

5/8

Step-by-step explanation:

If 3/8 IS raining, then the remaining 8ths is NOT raining. 8 - 3 = 5. So, 5/8 is NOT raining.

I hope this helps!

Answer:

5/8

Step-by-step explanation:

To find the probability of it not raining, subtract 3/8 from 1.

1 - 3/8

= 5/8

Since the probability of it raining is 3/8, this must mean that during the rest of the time, it will not rain.

So, the probability of it not raining is 5/8

The value of (3.9 × 10⁻³) + 0.0026 in scientific notation is 6.5 × 10⁻³.

Decimal numbers are numbers which has basically a whole number part and a fractional or decimal part after a point called decimal point.

Decimal number system describes the base 10 number system.

Given are numbers 3.9 × 10⁻³ and 0.0026 added together.

We have to do it in scientific notation.

0.0026 can be written as 2.6 × 10⁻³.

Adding these two numbers together, and taking the common term,

(3.9 × 10⁻³) + (2.6 × 10⁻³) = (10⁻³) (3.9 + 2.6)

                                        = (10⁻³) (6.5)

                                        = 6.5 × 10⁻³

Hence the answer of the sum of (3.9 × 10⁻³) + 0.0026 is 6.5 × 10⁻³ in scientific notation.

Answer:

a = undefined/no real solution

Step-by-step explanation:

Expand

24a - 22 = -4 + 24a

24a - 24a = -4 + 22

0a = 18

a = undefined/no real solution (when something is divided by 0 it becomes undefined)

The equation 24a - 22 = -4(1 - 6a) have no solution for the variable "a".

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Given:

equation 24a - 22 = -4(1 - 6a)

1. Distribute the -4 to the terms inside the parentheses:

  24a - 22 = -4 + 24a

2. Simplify the equation by combining like terms:

  24a - 22 = 24a - 4

3. Rearrange the equation by moving all the terms involving "a" to one side and the constant terms to the other side:

  24a - 24a = -4 + 22

4. Simplify  24a - 24a = -4 + 22:

  0 = 18

The equation 0 = 18 is not true, which means there is no solution.

Answer:

f(29) = - [tex]\frac{9}{290}[/tex]

Step-by-step explanation:

Step 1: substitute f(29) into the equation.

f(29) = 2(29 - 20)²⁻³

29 replaces x.

Step 2: simplify the exponent

f(29) = 2(29 - 20)⁻¹

2-3 is -1, so the exponent is -1

Step 3: distribute the exponent to the parentheses

f(29) = 2([tex]\frac{1}{29}[/tex] - [tex]\frac{1}{20}[/tex])

Since the exponent is a negative one, basically make it a fraction with the base as the denominator and the exponent as a numerator. I don't know too much about negative exponents, but this is how to factor in a -1.

Step 4: Distribute.

f(29) = [tex]\frac{2}{29} -\frac{2}{20}[/tex]

Step 5: Simplify before finding a common denominator (2/20 cancels out)

f(29) = 2/29 - 1/10

Step 6: Find a common denominator (290)

f(29) = [tex]\frac{20}{290}[/tex] - [tex]\frac{29}{290}[/tex]

Step 7: Simplify

f(29) = - [tex]\frac{9}{290}[/tex]

Answer:

20 n

Step-by-step explanation:

as both are exerting force on the same side i.e. to the west side with 10 N each the total net force is 10+10=20N and the table will move to the west side....

Thank you

The net force acting on the object will be 20 units and the direction will be the same as the direction of force applied.

All mass-bearing objects are attracted by gravitational force. Because it consistently attempts to bring masses together rather than push them apart, the gravitational force is referred to as attractive.

As we know, the gravitational force is given by:

[tex]\rm F = \dfrac{Gm_1m_2}{r^2}[/tex]

Where G is the gravitational constant.

m1 and m2 are masses.

r is the distance between the masses.

It is given that:

Boy 'a' and boy 'b' are pushing a heavy table in the west direction at the same time with 10 units of force each

The table will shift to the west side since both are applying 10 N of force to the same side, i.e., the west side, for a total net force of 10+10=20 N.

Total net force = 10 + 10 = 20 units

Thus, the net force acting on the object will be 20 units and the direction will be the same as the direction of force applied.

3(2x−14)+x=15−(−9x−5)

Step 1: Simplify both sides of the equation.

3(2x−14)+x=15−(−9x−5)

3(2x−14)+x=15+−1(−9x−5)(Distribute the Negative Sign)

3(2x−14)+x=15+−1(−9x)+(−1)(−5)

3(2x−14)+x=15+9x+5

(3)(2x)+(3)(−14)+x=15+9x+5(Distribute)

6x+−42+x=15+9x+5

(6x+x)+(−42)=(9x)+(15+5)(Combine Like Terms)

7x+−42=9x+20

7x−42=9x+20

Step 2: Subtract 9x from both sides.

7x−42−9x=9x+20−9x

−2x−42=20

Step 3: Add 42 to both sides.

−2x−42+42=20+42

−2x=62
