Answer:
169
Step-by-step explanation:
Given data
The function is
5x^2+7x=6
rearrange
5x2+7x-6=0
From the above expression, we can see that
a=5
b=7
c=-6
Substitute into the expression b^2-4ac
=7^2-4*5*-6
= 49-(-120)
=49+120
=169
Hence the answer is 169
Divide 468 in the ratio 4:5

Step-by-step explanation:
Ciara is making a new dance outfit. She needs 2 ⅓ yards of fabric for the shawl. She needs 1 ¾ years of fabric for the dress. If she has 3 yards of fabric, how much more does she need ?
Answer: 1 1/12 yards
Step-by-step explanation:
Since Ciara needs 2 ⅓ yards of fabric for the shawl and also needs 1 ¾ yards of fabric for the dress, the total yards needed will be:
= 2⅓ + 1¾
= 2 4/12 + 1 9/12
= 3 13/12
= 4 1/12 yards
Since she has 3 yards of fabric, the number of yards needed more will be:
= 4 1/12 - 3
= 1 1/12
Therefore, she needs 1 1/12 yards more.

For a school project, Sarah plans to build a scale model of an Egyptian pyramid. She will be using a scale of: 1 cm = 5 meters.
If the pyramid is 140 meters tall, how tall will her model pyramid be?
A.
56 centimeters
B.
28 centimeters
C.
32 centimeters
D.
28 meters
Answer:
B
Step-by-step explanation:
you divide 140 by 5 so 28 is the answer
B .28cm
Step-by-step explanation:
if 1cm=5m
then,140=×
1cm=5cm
cross multiply to get;
140÷5=28(cm)
=28cm

Mary simplified the math expression below. The steps that she took are shown. Which is the line where Mary first made her mistake. Line A: – 6 + 9 Line B: [8 + 5 x 3] – 6 + 9 Line C: – 6 + 9 Line D: 23 – 6 + 9 Line E: 23 – 15 Line F: 8
Answer:
Line E
Step-by-step explanation:
Given
The instructions in the question
Required
The first line of mistake
The question has missing details, as the original expression is not given;
Reading through the question, one can observe that, Mary made a mistake at Line E.
The expression on D is:
[tex]23 - 6 + 9[/tex]
The expression on E is:
[tex]23 - 15[/tex]
The actual result of D is:
[tex]23 - 6 + 9 = 23 + 3[/tex]
not
[tex]23 - 15[/tex]
Because:
[tex]-6 + 9 = 3[/tex]
[tex]-6 + 9 \ne 15[/tex]
With the available information, we can conclude that Mary's first mistake is at line E

Please help with 1234, due tonight would mean everything! Will give brainly!!
Answer: For 1, the answer is B since there is no rational number for sqrt17.
For 2, the answer is C since it has to be less than 11 whose square is 121 and larger than 10 whose squre is 100.
For 3 the answer is B. Just plug the x value into the equation. => y=1/2(-1)-2 => y= -1/2-2 => -2 1/2.
For 4 the answer is A because the graph first goes up then stys their staticly for a while then plumets down. It fits the description of the first one.

A bag contains 12 green cubes 5 blue cubes and 3 yellow cubes find each probability if you choose one at random
Answer:
2/5
1/6
1/10
Step-by-step explanation:
total number of cubes = 12 + 5 + 3 = 20
Probability of picking green cubes = total number of green cubes / total number of cubes = 12/30 = 2/5
Probability of picking blue cubes = total number of blue cubes / total number of cubes = 5/30 = 1/6
Probability of picking yellow cubes = total number of yellow cubes / total number of cubes = 3/30 = 1/10

Ok my question says "destiny and carla had a total of 3 gallons of paint to share for a project they had 1 gallon each yellow blue and red paint destiny used 3/8 gallon of yellow paint 1/2 of blue paint 1/4 of red paint carla used 1/4 of yellow 3/8 of blue and 1/4 of red then part a ask how much more paint in gallons did destiny use than carly
Answer: 1/4
Step-by-step explanation:
Since Destiny used 3/8 gallon of yellow paint, 1/2 of blue paint and 1/4 of red paint, the total paint used will be:
= ⅜ + ½ + ¼
= 3/8 + 4/8 + 2/8
= 9/8
= 1 1/8
Carla used 1/4 of yellow, 3/8 of blue and 1/4 of red. The total paint used will be:
= 1/4 + 3/8 + 1/4
= 2/8 + 3/8 + 2/8
= 7/8
The numybe of paint that Destiny use more than Carla will be:
= 1 1/8 - 7/8
= 2/8
= 1/4
Destiny used 1/4 paint more than Carla
What is the measure of angle DEA
Answer:
BAC and DAE are two acronyms for BAC and DAE, respectively. Since they are angles at a point, an arc measuring 204 degrees is 360 degrees. BAC is measured at 11 degrees. 5(11)° = 55° is the measure of DAE.

43 - d = -15
help i got 40 other question to finish
Answer:
D=58
Step-by-step explanation:
To Isolate your variable, you have to move 43 to the other side. So you subtract 43 from both sides. This gives you - d = -58. Divide both sides by negative 1 to simplify and you get d = 58

If you horizontally stretch the quadratic parent function, f(x) = X^2 by a factor
of 5, what is the equation of the new function?
9514 1404 393
Answer:
g(x) = x^2/25
Step-by-step explanation:
For a horizontal stretch by a factor of k, x is replaced by x/k.
g(x) = f(x/5) = (x/5)^2 = x^2/25
The new function is ...
g(x) = x^2/25

Answer:
$30.41
Step-by-step explanation:
To find the tax she paid take the total amount times the rate of tax
24.20x.05=1.21
Then add the tax to the amount she paid before tax was added and the tip
$1.21+$24.20+$5=$30.41
So she spent $30.41 at the restaurant
