Given the slope of the line containing the points (7 , b) and (-2 , 5) is 4/9, find the value of b
Answer: b=9
Step-by-step explanation: To find the slope we use: y2-y1/x2-x1
Which would then be: 5-b/-2-7= 5-b/-9
Then we have to find a number for b that would give us -4 as the numerator. That number would be 9
This would give us 4/9 which is the slope we already had.

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,340 ft Determine the flag's width and length if the length is 390 ft greater than the width.
Answer:
Step-by-step explanation:
L=W+390, W=L-390
P=2(W+L), P=2340
2(L-390+L)=2340
2L-390=1170
2L=1560
L=780ft

Solve the equation for x:
5x – 4 – 9x
4(x - 5)
Answer:
x = 2
Step-by-step explanation:
5x – 4 – 9x = 4(x - 5)
-4x -4 = 4x -20
-4x -4x = -20+4
-8x = -16
x = -16/-8
x = 2

Dave said that these triangles are similar. Is it false or true?
Answer:
false
Step-by-step explanation:
the sum of the angles is 180, for the first triangle B is 180-(60+79)= 41°. and for the second F = 180-(60+42) = 72°. therefore they're not equal / similar.

A coach is ordering jerseys for the school.
• The coach pays a one-time fee of $10.
• The coach also pays $12 for each shirt ordered.
Which function can be used to find t, the total amount the coach pays in dollars when c shirts
are ordered?
A t = 12c + 10
Bt = 100 - 12
Ct = 120 - 10
D t = 10c + 12
Answer:
10c + 12

A highway sign shows a speed limit of 60 miles per hour. Which of the following car speed measurements represent the same level of accuracy compared to the speed limit sign? Check all that apply. A. 64 mph B. 56 mph O C. 48 mph O D. 68 mph
Answer:
B and C
Step-by-step explanation:
IT is found that B. 56 mph and C. 48 mph car speed measurements represent the same level of accuracy compared to the speed limit sign.
What is speed?Speed can be calculated as the ratio of distance traveled to the time taken
We can see that As the speed limit on the highway is 60 miles per hour and the speeds mentioned above are below the speed limit.
The legal top speed at which a vehicle may travel on a specific section of road is determined by speed limits for road traffic, since they are utilized in the most of countries.
On a traffic sign, it is known that the maximum allowed speed is typically displayed and expressed in kilometers per hour (km/h) or miles per hour (mph).

Sophia cut a piece of wood that measured 10.2inches but she was supposed to cut 16 inches what is the percent error
Answer: 35.80 %
Step-by-step explanation:
Given
Sophia mistakenly cut 10.2 inches
The actual cut should be 16 inches
[tex]\Rightarrow \% \text{error}=\dfrac{\text{Actual dimension-Faulty dimension}}{\text{Actual dimension}}\times 100\\\\\Rightarrow \% \text{error}=\dfrac{16-10.2}{16.2}\times 100=35.80\%[/tex]

Elena bowls two games on Saturday. Her score in the second game is 30 more than ¾ of her score the first game. Elena's total score for the two games is 478. Write and solve an equation to demonstrate the points scored in her second game.
Answer:
222 = score in 2nd game
Step-by-step explanation:
Let x = score in 1st game
3/4(x) + 30 = score in 2nd game
x + 3/4(x) + 30 = 478 Multiply thru by 4 to eliminate the fraction
4x + 3x + 120 = 1912
7x + 120 = 1912
7x = 1792
x = 256
3/4(x) + 30 = 3/4(256) + 30
= 192 + 30
222 = score in 2nd game
Check: 222 + 256 = 478

Solve this inequality:
16x - 33x < -12x + 30
A. x < -6
B. x > 6
C. x > -6
Answer:
x > -6.
Step-by-step explanation:
16x - 33x < -12x + 30
Add 12x to both sides:
16x - 33x + 12x < 30
-17x + 12x < 30
-5x < 30
x > 30/-5
x > -6
(Note the inequality signs flips because we are dividing by negative 5).

question number four pls help I will mark brainiest
Pls help find the surface area
Answer:
114
Step-by-step explanation:
17 + 8 = 25
25 ÷ 2 is for one triangle.
25 ÷ 2 = 12.5
12.5 x 4 = 50
(4, because there are 4 triangles)
Then, 8 x 8 is for the middle square, which is 64
64 + 50 = 114
So, The surface area is 114
